Establishing Character Moment/Live-Action TV

"Drunk: The Independents were a bunch of inbred cowardly pisspots should have been killed offa every world spinning.
 * At the end of the first aired episode of Firefly, Mal.
 * A deeper one from the same episode is when he
 * Also, in the same episode:

Mal: Say that to my face.

Drunk: I said, you're a coward and a pisspot. So what are you going to do about it?

Mal: Nothing. I just wanted you to face me so she could get behind you.

[And * WHACK!* Zoe lays the drunk out with the butt of her mare's leg.]"

"Mal: You don't know me, son, so let me explain this to you once: If I ever kill you, you'll be awake. You'll be facing me, and you'll be armed."
 * Niska's introduction in the same episode is one long lampshade of the trope.
 * In the intended pilot, the first glimpse the audience gets of Wash is a scene of him playing with plastic dinosaurs while he's supposed to be piloting the ship. That's pretty much all we needed to know.
 * From the same pilot:

"Sheldon: Um Penny...that's where I sit.
 * Firefly also pulls a fake example with Simon in the (intended) pilot:
 * His real ECM comes later,
 * In the film, Serenity, the Operative's first scene is him killing the doctor who let Simon and River escape, citing the Roman practice of having generals fall on their sword. Using a Pressure Point technique, he gives the doctor a little help, and comforts him as he dies. And when the doc's assistant starts to run for help, he stops her with a word and asks for help getting some more records. We know he's dangerous, practical, and has an odd sense of honor. The Oner which follows introduces the uninitiated to Serenity's crew in a similar fashion.
 * In iCarly, "iPilot" introduces Mrs Briggs as a Sadist Teacher, Principal Franklin as a Reasonable Authority Figure, Sam as a mean bully, Carly as sassy and the only one who can control Sam, and Freddie as the Dogged Nice Guy tech nerd Butt Monkey with a crush on Carly (to be honest, for Freddie, it's more like a constant Establishing Character Episode as nothing goes right for him), and finally, Spencer as a wacky artist.
 * In the first episode of Buffy the Vampire Slayer, Giles attempts to remind Buffy of her duties, she sneers, "Blah, blah, I've heard it okay?" Cements her character pretty solidly, but she has many much cooler moments.
 * Spike's very first scene is smashing into a "Welcome to Sunnydale" sign in his car and strutting out wearing a leather coat and Sid Vicious mannerisms. Establishes his character well...but at the end of the episode he kills the previous season's Chosen One villain and his prophecy devoted mooks saying that from now on there would be less ritual and more fun which sets him up as the new Big Bad and his role of subverting the traditional ancient villain behavior.
 * Darla's very first scene is the first scene of the first episode. Well, you know the plot, so it isn't a spoiler that the cute blonde in the Catholic schoolgirl outfit being led astray by the tough guy in the biker jacket is not an innocent. It's Darla, luring him into a place where she can rip his throat out. Not only an ECM for Darla but a defining moment for the show and a scene with a gigantic HSQ for the unprepared.
 * The pilot episode has Xander babbling incoherently when confronted with a pretty girl (Buffy), Cordelia seeming nice until she's confronted with shy, nerdy Willow, and Willow herself eating lunch alone and offering to move when someone comes to sit in her spot.
 * More specifically, Willow talks about losing her Barbie doll as a child and when Buffy asks if she got it back, Willow replies happily "Most of it" as if this was a positive. Saying the line that way got Alyson Hannigan the role and it establishes the character for the first three seasons.
 * Riley's friend Forrest seemed nice enough until he suggested that they use Buffy as bait to lure Spike.
 * Richard Wilkins asking the deputy mayor to show his hands.
 * Mr. Trick greets a drive-in guy then eats him.
 * Faith casually beating up a vamp while greeting Buffy.
 * Adam asking a boy what he is then killing him.
 * When we first see Giles, Buffy asks him about books (she means school books) and he gleefully slams a thick tome with the title "Vampyr" in front of her. It's clear from there on that Giles will be a constant source of supernatural booksmarts for the slayer.
 * Spike roughs up the Anointed One's minions but then an Ominous Music Box Tune rises and everyone turns to see this spooky woman in white. Drusilla has arrived.
 * In Mash, during Charles Emerson Winchester's first episode, he spends a lot of time showing his spoiled upper class roots. But at the end of that episode, he actually turns one of Hawkeye's jokes back on him. Hawkeye isn't pleased, but all Winchester does is say "Please. Mozart." This made it clear he was going to be a much more complex character than Burns.
 * In The Big Bang Theory's pilot, we learnt everything we needed to know about Sheldon when Penny accidentally stole "his spot".

Penny: [flirtingly] Sit next to me.

Sheldon: [clueless] ...no, I sit there.

Penny: What's the difference?

Sheldon: "What's the difference?"

Leonard: Here we go.

Sheldon: In the winter that seat is close enough to the radiator to remain warm, and yet not so close as to cause perspiration. In the summer, it's directly in the path of a cross-breeze created by opening windows there and there. It faces the television at an angle that is neither direct, thus discouraging conversation, nor so far wide as to create a parallax distortion. I could go on, but I think I've made my point."

"Doctor: Hello. I'm the Doctor. Basically... run."
 * During the Supernatural pilot, Dean was this snarky, flirty, junk-food-loving Badass and the fans loved him for it but when it came to "I can't do this alone." "Yes you can." "Yeah, well, I don't want to," his fate as a complicated woobie was sealed.
 * While remaining still quite whiny and closed off, Sam's first defining moment as the snarky little brother came with this line in the pilot: "You smell like a toilet."
 * Castiel's first scene. He walks serenely into the barn where Dean and Bobby are waiting while they shoot him, the barn shakes, and the lights explode overhead (the last two are direct results of his presence). Despite the chaos, he never flinches or even blinks, and he never takes his eyes off Dean.
 * Death, often considered by the fans to be the best entrance in the history of television.
 * As each incarnation of the Doctor in Doctor Who is often vastly different, each of them have at least one Establishing Character Moment in their respective first appearances. For example, the First Doctor persistently acting like a senile old man to the two teachers in "An Unearthly Child", or the Fourth Doctor's bizarre choices for new outfits in "Robot". The Ninth Doctor's first line is "Run!", which pretty much sums up the entire show in a single word. Endured a heavy Lampshade Hanging in "The Christmas Invasion", as the Tenth Doctor wonders who he is, eventually receiving his own Moment as he kills the Sycorax leader, remarking "No second chances. I'm that sort of man". (Of course, before that in his very first appearance, his first reaction was to be intrigued and confused by his new teeth, which established another factor of his personality quite well -- there's a Ditz somewhere in there.)
 * Note that, as well as showing what makes their Doctor different, each regeneration also needs a moment where they establish themselves as still essentially being the Doctor. This will normally be the moment where they step up to save the day with a brilliant, improvised plan and declare themselves as humanity's (and the universe's) protector. For example, the Eleventh Doctor's now legendary speech to the Atraxi in which he literally takes his place among the other regenerations:

"John: Is that it?
 * Similarly, each incarnation of the Master receives their own Establishing Character Moment, though due more to the length of time between appearances than the disparity of the portrayals. Examples include Roger Delgado's immortal line "I am usually referred to as the Master. Universally.", while John Simm had the less immortal but no less impressive "Why don't we stop and have a nice little chat while I tell you all my plans and you can work out a way to stop me, I don't think!". Anthony Ainley's ECM doesn't even involve lines - it's his signature sinister cackle during "Logopolis".
 * Jack Harkness's first line in the new series is "Excellent bottom." ... While staring at Rose Tyler's ass through binoculars, who is dangling thousands of feet in the air from a rope tied to a barrage balloon. His fellow soldier thinks the line is aimed at him, to which Jack responds by patting the guy's bottom before setting out to go rescue Rose.
 * Sherlock has a show-stopping one of these when he first meets John in A Study in Pink. It is, naturally, a startlingly accurate analysis of John and his background after having known the man for literally all of two minutes. Watch the epicness here.

Sherlock: Is that what?

John: We've only just met, and we're gonna go look at a flat?

Sherlock: Problem?

John: We don't know a thing about each other. I don't know where we're meeting, I don't even know your name.

Sherlock: I know you're an army doctor and you've been invalided home from Afghanistan; I know you've got a brother who's worried about you but you won't go to him for help because you don't approve of him; possibly because he's an alcoholic - more likely because he recently walked out on his wife, and I know that your therapist thinks your limp's psychosomatic; quite correctly, I'm afraid. That's enough to be going on with, don't you think?"

"Rebecca (patient of the week): Did you think you were dying [when you had the infection]?
 * It also follows up with defining John's social intelligence against Sherlock's analytical one:
 * Every single person on Twenty Four gets one of these, to the extent that Television Without Pity has started timing how many seconds it takes a new castmember to establish their character. (The record is Morris O'Brien, at 4.)
 * This takes special note as throwing almost all Power Rangers cliches out the window. The opening of Power Rangers in Space had the Red Ranger Andros infiltrating the Council of Evil wearing a concealing cloak. He was working to get information on this "Grand Plan" being set up by the council. After being discovered, he fought his way out and escaped. No prior ranger was this devious or bold as to attempt something like that. Said cloak later becomes his Memetic Outfit in both teamup episodes he appears in.
 * House manages to have a few of these in the pilot, showing off his assholishness ("Brain tumor, she's gonna die, boring"), his pride ("Patients don't want a sick doctor") and his need to butt into other people's lives. But what really stands out for most people is this little bit of conversation:

House: I hoped I was dying.

Rebecca: So you hide in your office, refuse to see patients because you don't like the way people look at you. You feel cheated by life so now you're gonna get even with the world. You want me to fight this. Why? What makes you think I'm so much better then you?

House: When you're scared, you'll turn into me.

Rebecca: I just want to die with a little dignity.

House: There's no such thing! Our bodies break down, sometimes when we're 90, sometimes before we're even born, but it always happens and there's never any dignity in it. I don't care if you can walk, see, wipe your own ass. It's always ugly, always. [Pause] You can live with dignity, we can't die with it."

""Hello, sick people and their loved ones! In the interest of saving time and avoiding a lot of boring chitchat later, I'm Doctor Gregory House; you can call me Greg. I'm one of three doctors staffing this clinic this morning. This ray of sunshine is Doctor Lisa Cuddy. Dr. Cuddy runs this whole hospital, so unfortunately she's far too busy to deal with you. I am a bored ...certified diagnostician with a double specialty of infectious disease and nephrology. I am also the only doctor currently employed at this clinic who is forced to be here against his will. But not to worry, because for most of you, this job could be done by a monkey with a bottle of Motrin. Speaking of which, if you're particularly annoying, you may see me reach for this. This is Vicodin. It's mine. You can't have any. And no, I do not have a pain-management problem; I have a pain problem. But who knows? Maybe I'm wrong. Maybe I'm too stoned to tell...Now, who wants me?""
 * Wilson too in the pilot, when he lies to House about the patient being his cousin so that House can get out of his funk of the moment and start seeing regular patients again. This set up his "Trying to do good by being a Manipulative Bastard" side.
 * House established himself pretty well to a clinic full of patients early in the first season with this little number:

""I am superior [to humans], sir, in many ways. But I would gladly give it up to be human.""
 * Jeeves and Wooster managed to use this trope on top of its own inversion. When Jeeves first shows up, he very calmly tidies up Bertie's room in what seems to be a matter of seconds and whips him up a hangover antidote, completely unfazed by the fact that his new employer is so preposterously hung over that he can't even form any semblance of coherent speech. Heck, Bertie doesn't act like himself for the full first five minutes of the show. He doesn't even talk.
 * Star Trek: The Next Generation, anyone? Pretty much of all the characters get an establishing moment at some point in "Encounter at Farpoint":
 * Captain Picard appears in silhouette through the window of the Enterprise-D, making a captain's log entry. The first appearance of a remarkably different captain to Kirk.
 * And then there's his speech to Q. There's a reason he's the Trope Namer there, folks. Plus the moment when he commands them to take an untested starship on its maiden voyage to well-beyond-regulation-safety-limits.
 * Commander Riker boards the Enterprise and immediately has a talk with Captain Picard about his previous service. Picard brings up a time when Riker refused to let a previous CO beam down to a planet (which becomes a running theme between the two of them in the later series). Picard gruffly asks if Riker has any respect for a Captain's rank. Riker, without being either defensive or smug, says that a Captain's life means more. Picard suddenly smiles and says "Welcome aboard the Enterprise." This scene is more or less sums up how their relationship is going to go for the rest of their time serving together.
 * Data gets confused by a human figure of speech--and upon discovering its meaning, immediately reels off various synonyms like the walking encyclopedia he is.
 * And then there's a little later in the episode when Riker finds him trying to whistle in the holodeck (he finds how easily humans can do it amazing) and makes the statement:

"Geordi: A remarkable piece of bioelectronic engineering by which I quote "see" much of the EM spectrum ranging from simple heat and infrared through radio waves etcetera etcetera and forgive me if I've said and listened to this a hundred times before."
 * Geordi's establishing shot was probably during his check up in sick bay, where we get a pan across the VISOR - the means by which he sees - and Geordi offers the Doctor an explanation for its purpose:

"O'Neill: Teal'c, I saw you stand up to a god. You refused to kill. I saw you make that decision... In that moment I learned everything I needed to know to trust you"
 * After harassing the crew, Q appears on the Enterprise's main viewer. Worf draws a gun and is ready to shoot, prompting Picard to ask him if he want to put a hole in the main screen. The Son Of Mogh may be a little hot-headed, like all Klingons, but damned if he's gonna back down from people screwing with his Captain and his ship.
 * Worf is re-established on Deep Space Nine when he arrives on the station and promptly walks up to a jerkass Klingon who's being all loud and rude in Quark's bar, and proceeds to knock his ass clean out.
 * Wesley might have some unfortunate associations but to be kind, his early appearances (begging to get to see the bridge of the Enterprise, getting overexcited in a holodeck and falling in the water, etc.) established him pretty well as a smart, eager kid and probably would've been okay if they left it like that. Of course it was all downhill from there...
 * Q's first appearance--as a middle ages Sea Captain taking in iambic pentameter, is almost jocular (Soundtrack Dissonance aside)--but a few seconds later he's freezing a crewman solid with a glimpse. Enter...chaos.
 * Tasha's impassioned speech about how much the Federation did for her and how much of a mockery Q's "Court and Jury" setting was pretty much established her attitude, and hinted heavily at her background.
 * The first thing Deanna Troi does on screen is start sensing things and recounting what she's feeling. Then later she talks right into Will's head via a kind of telepathy, establishing their romantic history.
 * The first thing Dr. Pulaski does in the second season is not report for duty. She's in the bar at the time, talking with Deanna. As Worf says, "Not the best way to meet your captain." Most of the more notable moments she has in the rest of her first episode involve insulting Data repeatedly, even though he can't be insulted, which just comes off as pure spitefulness rather than the ribbing McCoy would give Spock.
 * In Parks and Recreation, the episode that introduces Chris and Ben has one for each. First, Chris's talking head segment in which he explains that he does everything necessary to be healthy and that he plans on becoming the first human being to live to 150 years. Then Ben finally opens up to Leslie about his reasons for trying to be so responsible and serious. Of course, the second they are introduced also has a much smaller example. Leslie claims that Chris is so positive that making eye contact with him is like staring at the sun, and Ben's first few words make him Chris's scape goat as he explains that they intend to reduce everything by 50%.
 * Rome is full of all kinds of Character Development, but the opening scene with main character Lucius Vorenus is fairly defining of his character. He suggests, under duress, that the best way to find a thief among the conquered tribes would be to crucify members of each clan one by one until they talk. He shows no pleasure at this, even slightly pained by their screams, but still does it, but when one gives him the information, he orders all of them to be taken down (while lamenting his own situation - pretty rich for a guy at the foot of a currently occupied cross). This sets up the moral overtones of most of the series, and shows how honorbound Vorenus is.
 * Mark Antony's ECM has to be the bit where he's shagging a random shepardess under a tree with his entire personal escort watching.
 * Incorrect. That was a moment, but his actual first scene did more to establish his character: strolling in to Caesar's tent covered in blood, bantering with Brutus, and then, when given a mission to accomplish on a strict budget, unabashedly stealing half the money anyway.
 * Both subverted and played straight in Scrubs. In the pilot episode, Kelso is set up as a nice father figure and Cox as a bad one. By the end of that episode, the roles are more or less reversed.
 * In the pilot of Thirty Rock, Liz "buying all the hot dogs" and the tour de force that is Jack's first scene.
 * Samantha Carter's first scene in Stargate SG-1 is well remembered...for its cringe-inducing hilarity, including the so-not-cheesy line "just because my reproductive organs are on the inside instead of the outside doesn't mean I can't handle whatever you can handle". Thankfully, she improved after her actress, Amanda Tapping, pointed out that she should just contribute to the team without constantly going "Hey, I'm a girl! Girls rock!" The "reproductive organs" line was mocked twice in later seasons.
 * Nonetheless, her early defensiveness is not so strange if you consider her position in two male dominated fields. She's probably gotten plenty of crap before coming to the SGC.
 * See Daniel and Jack's memorable introductions in The Movie in the appropriate section.
 * Teal'c had a good ECM in Stargate SG-1 as the leader of a Jaffa raiding party into what turned out to be a nearly deserted top-secret storage facility. His men mop the floor with the guards, abduct one and leave. Teal'c is clearly a particularly Badass Proud Warrior Race Guy...but as you can tell from his facial expressions throughout this scene, he's really not happy about this. O'Neill considers the moment that Teal'c disobeys orders and helps them escape to be his establishing character moment:

""So, my friend, if you want to start using American military strength as the arm of the Lord, you can do that. We're the only superpower left. You can conquer the world, like Charlemagne! But you better be prepared to kill everyone. And you better start with me, because I will raise up an army against you and I will beat you!""
 * This Is Wonderland: Alice is introduced waiting outside the courthouse for someone who isn't coming. Nancy shows up, says he isn't coming, and then leaves, because her job is done. Zona is trying to keep multiple phone conversations going simultaneously but still has time to help Alice, if only a little. Elliot is some scruffy weirdo who knows his way around the courtroom and checks out Alice's legs. James - the guy who didn't show up - doesn't show up, and when he does, he's wearing no pants under his desk. And Judge Frasier wears running shoes into court, sings to himself, and calls Alice "kiddo".
 * Rachel Menken's two scenes in the pilot episode of Mad Men establish her character wonderfully. But if you have to pick just one moment, it would have to be when she puts out her cigarette in the cocktail shrimp.
 * Don Draper's is when he drives home from the train station at the end of the episode - after we've seen him having sex with his mistress - and arrives at a home, where we realize he has a wife and children.
 * One possible ECM for Joan Holloway's is the moment from the pilot, where she tells Peggy to "go home and put a paper bag over your head", but a case can be made for the stunningly perfect meta-shot in "Babylon" where she bends over a table facing away from what she knows to be two-way glass, letting all the execs get a nice, long look at her ass.
 * And then they salute it.
 * Peggy Olsen's has to be when she lets Pete into her apartment in the pilot; she knows she shouldn't be sleeping with a drunken, soon-to-be-married man, but does it anyway because she thinks she's grown-up enough to handle it.
 * Roger Sterling, in "Red in the Face", having hit on Betty Draper in front of Don: "At some point, we've all parked in the wrong garage."
 * The first scene of Monk has him at a crime scene in a woman's home, when he says "the stove". A policeman points him to it, and he responds "No. The one at home. I think I left it on".
 * In the very first episode of Noah's Arc, Ricky has two. The opening scene has him flirting up and getting a number from a guy on the beach. The thid or so scene that we see him in next hes in his store having sex with his employee.
 * The West Wing has President Bartlet enter a meeting with Religious Right representatives quoting, "I am the Lord your god; thou shalt worship no other god before me!" He then blows right through the demands they were making of his staff (they were wanting compensation for being publicly insulted by Josh), relays a story of an implied death threat being sent to his 12-year-old granddaughter by an extremist Christian group, and then demands that they publicly denounce said group -- "...and until you do, you can all get your fat asses out of my White House. CJ, show these people out." Not only was it an Establishing Character Moment, it basically made the character; before then, the plan was to focus mainly on the White House staff with the president only appearing about four times a season, but Martin Sheen turned in such an impressive performance that they made Bartlet a regular.
 * Toby grumpily complaining to stewardesses while showing detailed knowledge of the aircraft and refusing to shut his cell phone off.
 * Sam sarcastically dismissing a journalist, while catching an attractive woman's eye...
 * Josh in trouble for speaking too candidly to a right-winger. And Donna's reaction to Josh's problem, being supportive yet sassing him for his faux pas.
 * CJ at the gym, talking about her busy life and seeming to have it all together--and then falling off the treadmill.
 * The 7-minute walk-and-talk at the beginning of the pilot is Leo's, showing his competence, prickly nature, and the affection he holds for both the job and the people he works with.
 * There's also an argument to be made for his calling out Bartlet in "A Proportional Response":

"Morgan: I thought I was calling the Office of Supreme Genius.
 * Some minor characters also get some very notable ones including Lord John Marbury ("Geraaaaaaaaaaaald?"), Ainsley Hayes (a smart and loquacious Blonde Republican Sex Kitten) and Lionel Tribbey.
 * In the pilot episode for The Sarah Connor Chronicles, Cameron has several moments that could count, from running over Cromartie with a truck and uttering the iconic "Come with me if you want to live" line, to her brawl with Cromartie that levels an entire house to her nonchalantly beating up a group of drunks while stark naked. It's up to the viewer to figure out which one works best.
 * Her flirting with John showed she operated differently than Ahnold.
 * Criminal Minds pilot episode "Extreme Aggressor" gives us a few ECM's. Gideon has two, first when he has a bit of Sensory Overload and completes the profile hours before anyone else, and second, when he takes on the Footpath Killer completely unarmed. Morgan's is his flirting with the FBI trainees. Reid's is his rattling off of his eidetic memory, IQ level, and the fact that he can read 20,000 words a minute and concluding with a deadpan "yes, I'm a genius". Hotch's is when he confesses to Gideon that the reason he keeps shooting down Haley's choices for baby names is because they're all first names of well-known serial killers. Elle's is her startling transformation from Innocent Bystander to Action Girl when she gets the UnSub to walk into a house with her, then cuffs him before he can flee. And Garcia's, of course, is her phone banter with Morgan:

Garcia: Well, gorgeous, you've been re-routed to the Office of Too-Frickin'-Bad."

"Kira: Yes?
 * Emily Prentiss joins the team in "The Last Word", but doesn't get hers until "Lessons Learned", when she proves her usefulness to the team by speaking flawless Arabic and allowing them to realize the next suicide attack is set for the next crescent moon.
 * David Rossi's very first scene, in "About Face", establishes that he's the anti-Gideon: he shoots down a bird (something always associated with Gideon).
 * Get Smart. Larabee. Three words: "Follow That Car!!"
 * William Shatner expressing his dislike for marshmallows in T. J. Hooker.
 * In the first episode of The Wire, narcotics cop Shakime "Kima" Greggs is part of an operation to arrest some drugdealers in possession. Which they do. Carver pulls a pistol out of the car, when Kima casually walks to the car and pulls out a shotgun. "Two guns."
 * Also the introduction of Ziggy Sobotka in season 2. "You're not getting your dick out in here again!". Cue Male Frontal Nudity.
 * In Marlo Stanfield's first appearance, we see Bubbles and Johnny have a gun pulled on the both of them. Marlo enters and asks what's going on. When told, he simply says "Either do it or don't, but I've got someplace to be." Characterizing him as someone who, in all honesty, doesn't give a fuck about human life if it doesn't affect him.
 * "These are for you, McNulty. This one is going up your narrow fucking Irish ass. And this one is in your fucking eye." Rawls introductory scene is nothing if not memorable, and it establishes his adversarial relationship with McNulty right from the get go. "You have my attention, Detective."
 * In Star Trek: Deep Space Nine, the first thing we see of Kira Nerys is her shouting match with a member of the provisional government. Although her character softens over the course of the series--and we find out why she is the way she is--she never loses that fire. Or, for that matter, her contempt for most of the provisional government.
 * The scene that immediately follows is arguably the same for Sisko: A firm, but polite and pleasant officer...who is not to be trifled with.

Sisko: (smiles) I'm Benjamin Sisko.

Kira: I suppose you want the office.

Sisko: Well, I thought I'd say hello first...(smile gains the tiniest hint of malevolence) and then take the office. But we can do it in any order you like."

"Q: (astonished) You hit me! Picard never hit me!
 * The seventh episode of the series really establishes what kind of commanding officer Sisko is in comparison to the then standard, Picard. When confronted by Q, the first thing that Sisko does is knock his ass to the floor with one punch.

Sisko: I'm not Picard."

"Vila: Blake, Kerr Avon. When it comes to computers, he's the number two man in all Federated Worlds.
 * Ashes to Ashes had three of the same characters from Life On Mars, but manages to give them each an ECM for those members of the audience who weren't familiar with LOM. Gene Hunt's tour-de-force entrance - "Today, my friend, your diary entry will read, 'Took a prozzie hostage and was shot by three armed bastards.'" - Ray bouncing Markham's head off the Quattro, and Chris's insistent "I'm not nervous. I'm just cautious.". For the new characters, Shaz's is her dancing to the Walkman, and Alex's know-it-all use of finger quotes when she talks to Gene, calling him a construct.
 * When Keats joins the cast in Season 3, his ECM is his combination Face Heel Turn / "The Reason You Suck" Speech to Gene, where his darker nature is revealed after an entire episode of seeming as if he's just a harmless by-the-book pencil pusher from D&C.
 * The pilot for Lost is full of these. For example, in the very first scene, Jack wakes up in the jungle, stumbles onto the beach, takes in the carnage before him, and immediately begins running around saving people's lives. And the first time we see Boone, he is trying to do the same thing and failing miserably at it.
 * The first thing we see Davy Crockett do in his Disney mini-series? Kill a bear with a knife. Badass status set.
 * In Season 8 of Degrassi Clare and Alli are given an effective moment, based on the comparison between the two, setting their roles in the series. Clare is with Darcy (Clare's older sister), who is telling Clare to be more normal 'like Sav's sister.' Due to Clare's wearing her old private school uniform to a public school and spouting off random facts as Darcy comments on how different they are. On the other side, we see Sav trying to tell Alli to stop wearing clothes that are so evocative, as their parents won't approve. Due to Alli's desire to be seen and popular. While Clare had appeared in an earlier season, this defined her character a lot more.
 * The IT Crowd is full of this. Roy is introduced by eating while completely ignoring a ringing phone. Moss is introduced giving a long Techno Babble explanation for a common computer problem, only to discover that they hung up halfway through it, which he shrugs off as a mistake on their part. Jen and Denholm Reynholm are introduced together - he by giving her a 'long, hard stare', her by how she takes his weirdness mostly in her stride, and trying to take advantage of it. Richmond is introduced by his horrifying entrance immediately followed by him engaged in pleasant conversation. Douglas Reynholm was introduced by barging into his fathers funeral, yelling FATHEEEEEEEEEEEEEEEEEER! and getting into an extended slap-fight with the priest for no reason.
 * A good introduction episode does this with the main cast. While they get more 'real' moments later, Space Cases actually gets credit for the shortest version ever. Each main cast member gives a single line, in some cases, but it gives an impression of their personality.
 * Guinevere's introduction in the BBC series Merlin was particularly sweet and understated. While Merlin is put in the stocks for assaulting Arthur, she introduces herself and playfully banters with him but assures him that what he did was heroic.
 * Especially lovely is the fact that she dismisses Arthur as "a bully" and later says to Merlin (about Morgana): "Some people are just born to be queen! Not that I'd want to be her. I mean, who'd want to marry Arthur?" Oh delicious irony.
 * Merlin also gets a pretty decent Establishing Character Moment when he first enters Camelot. After witnessing a man get executed for the crime of sorcery and learning that magic is forbidden in Camelot, what's one of the first things he does? Use his magic to save someone's life.
 * Gwaine in season 3 appeared throwing the first punch in a bar fight (it originally had nothing to do with him) and he joined in for the fun of it. He later took a hit for Arthur despite not even knowing him.
 * From his first appearance in the last episode of season 3, we hardly know anything about Percival other than he arrived with Lancelot to help save Camelot. The first episode of Season 4 shows him endangering his own life to save three frightened children by carrying them to safety and abandoning his only means of a weapon.
 * The first we see of Burn Notice's Michael Westen is him being cut off by the titular notice in the middle of making a payment to a warlord. Since he can no longer come up with the money, the warlord promptly orders him killed. Mike lures his captors into the bathroom, uses his signature Combat Pragmatist ways to take them out, then escapes on a nearby motorbike. Then he lures the warlord's men, who are chasing him in a car, into crashing in the middle of a marketplace, which causes everyone there to point guns at them while Michael makes his way to the airport. Cool head in a crisis, a good fighter, a gift for improvisation, and a Batman Gambit that lures his stronger foes into a vulnerable position: Michael Westen, ladies and gents.
 * Fiona's is her sitting at Michael's bedside in a Miami hotel room, kicking him awake and then picking a fight while flirting with him.
 * The first view we get of Sam Axe is him flirting with a hot girl in a bikini and drinking, putting the "Crouching Moron" in Crouching Moron, Hidden Badass.
 * Madeline doesn't even have to be onscreen for hers - Fiona tells Michael his mother knows he's in Miami, and all you see is Michael's terrified reaction, as well as his voiceover admission that Maddie should have been a communications specialist for the NSA. She later shows up to nag Michael into taking her to the hospital for imaginary medical problems and nag him about never spending any time at home.
 * Jesse shooting his way out of an ambush after he was sold out by his handler showed he wasn't just some desk jockey.
 * A number of villains get these, too. Among the recurring ones:
 * Carla, before even appearing in person, directed Michael to the site of a nasty shootout and a terrified, Bound and Gagged man who, as she explained, had tried to escape her organization with his family, who are now hostages: she's the ruthless, Manipulative Bastard handler who will not accept your resignation.
 * Victor, the subject of the page quote, meets Michael in a chess park, makes some graphically violent "jokes", and when Michael tests him, threatens to shoot him in the crotch: He's Michael's Laughing Mad, Ax Crazy Evil Counterpart.
 * Larry shows up smiling, laughing, joking with Michael, and offering to cut him in on a murder-for-hire job: he's a Friendly Enemy with aspirations to The Corrupter.
 * Brennen is introduced having already kidnapped a child to extort cooperation from his mother, circumvents the heroes' intervention without even knowing about them by strapping a hidden bomb to the kid, walking away clean with everything he wanted, and being incredibly smug about it: he's a Complete Monster who is unfortunately also an Insufferable Genius.
 * Blakes Seven, for Avon:

Nova: Who's number one?

Vila: The guy who caught him. [To Avon] You've got nothing to be ashamed of. D'you know, he came close to stealing five million credits out of the Federation Banking System.

Blake: What went wrong?

Avon: I relied on other people."

"There was a time when this whole quadrant belonged to us! What are we now? Twelve worlds and a thousand monuments to past glories. Living off memories and stories, and selling trinkets. My god, man! We've become a tourist attraction. "See the great Centauri Republic - open 9 to 5 - Earth time.""
 * In Babylon 5, Londo gets one for not only himself, but the entire Centauri Republic in the pilot movie.

"Jerri: Hello, I'm Jerri Blank and...and I'm an alcoholic. I'm also addicted to amphetamines, as well as main line narcotics. Some people say I have a sex addiction, but I think all those years of prostitution was just a means to feed my ravenous hunger for heroin. It's kinda like the chicken or the nugget. The point is, I'm addicted to gambling. Thank you. (pauses) Oh, and...my daddy's in a coma. :("
 * Many characters from Star Trek: The Original Series get their moment in the episode "The Naked Time". It establishes the dichotomy that defines Kirk's character (Married to the Job vs. Boldly Coming) as well as the one that defines Spock's character (he's Not So Stoic after all, forever cementing him as the Stoic Woobie). McCoy is shown to be a hardworking and dedicated medic, who is also gruff and deeply stubborn; Scotty is established as Mr. Fixit and a Gadgeteer Genius (especially when working in tandem with Spock), and the episode marks his first use of Scotty Time. Sulu's rampage with the fencing foil establishes him as a Fan of the Past and sets him up to take take several levels in badass over the course of the series and films.
 * The first 10 minutes of the pilot of Skins show Tony working out, coolly covering for his little sister, and calling Sid to promise to get him laid. Sets him up as the bastard he is, and also shows his soft spot for Effy.
 * Strangers with Candy:

"Monica: There's nothing to tell! He's just some guy I work with!
 * Castle is at a party where he is signing the breasts of an attractive woman. His teenage daughter and his mother are both present: doing her homework and scouting for singles, respectively. As Castle mentions his boredom of the celebrity life to his daughter, someone taps on his shoulder. He turns around, and immediately likes what he sees. He asks her where she'd like her signature...and Beckett flashes her badge and drags him down to the precinct. Thus begins a beautiful partnership.
 * In the pilot episode of The Young Ones, we learn everything we need to know about Vyvyan when he crashes through the kitchen wall of the guys’ flat holding a severed human leg, then stomps over to the sink and kicks the basin clean off the wall.
 * The Shadow Line has several of these:
 * Jay Wratten's first scene has him delivering a No-Holds-Barred Beatdown in a lift to a man who insulted him.
 * Glickman's first appearance sees him tracking down and murdering a man who recognised him when he was in hiding, to establish that he really doesn't want to be found.
 * Farscape has many such moments.
 * In the first season, John Crichton hadn't quite developed into the Crazy Awesome character he became in series 2, but season 1 episode "Exodus From Genesis" did give the audience a preview: it involved commandeering a unit of clones produced by a gigantic Hive Queen alien to defeat the squad of Peacekeeper commandoes attacking the ship, ultimately fooling them into thinking that humans can clone themselves.
 * Zhaan gets a good one in "Throne For A Loss": after having to keep watch on a drug-addicted prisoner, she decides to help when the man begins showing signs of a very painful withdrawal. The man almost immediately attacks her in a frenzy, only for Zhaan to very calmly fling him aside; then, after quickly mixing a few chemicals, she applies the makeshift potion to her lips, and administers it to the prisoner by kissing him.
 * Aeryn got one in her very first episode; after awakening to find herself in a cell with Crichton, she ignores his attempt to introduce himself by kicking the crap out of him, pinning him to the ground, and demanding to know his rank, regiment and the reason for him being out of uniform.
 * After a long introductory episode, in which she's gone out of her way to kick, kiss and cry her way out of any danger that comes her way, Chiana is asked if she was the one who killed Sallis, her jailer. Chiana just grins. Possibly more telling is that after John leaves, the smile becomes a look of pain and regret.
 * Scorpius gets one in his first episode, too: already introduced as a mysterious, leather-clad figure that even the base commander fears, the true nature of his character are revealed when he passes Crichton in one of the base hallways, glances at him for a moment, and without raising his voice, promptly announces, "That man is an imposter. Seize him."
 * Veronica Mars begins with Veronica's monologue while she's spying on a couple. The kind of character Veronica is becomes especially clear when she says "$40 an hour is cheap compared to the long-term financial security sordid photography can secure you...your offspring...your new lover." Cynical, jaded, witty, and sexy. Veronica in a nutshell.
 * Angel tries to chat up a girl he believes is in danger but fails showing his sexy, brooding isn't gonna work on city girls.
 * Doyle telling Angel the world needs them to show that there's still love and compassion then tells off a homeless woman.
 * The opening scene of Gilmore Girls, which takes place in Luke's Diner, firmly establishes Lorelai and Rory's unique mother-daughter relationship, as well as a glimpse into grumpy Luke. It also contains many trademark Gilmore features, such as the girls' caffeine addiction, the rapid fire dialogue, and pop culture references.
 * The very first Friday night dinner does this for Richard and Emily, too. Richard nonchalantly handing a newspaper to Rory as he reads his became representative of his character and even appears in the opening.
 * The pilot of How I Met Your Mother does this:
 * Future!Ted makes his kids sit down and listen to him talk, telling them they're gonna be sitting there for a long time.
 * Marshall anxiously but earnestly practicing his marriage proposal to Lily on Ted.
 * Barney's first line: "You know how I've always had a thing for half-Asian girls?" Also, he says this on the phone while getting a shave at a ritzy salon.
 * Lily brassily gives a cab driver TMI on her and Marshall's sex life. Also, an establishing moment for the Lily/Marshall relationship: when the cab driver thinks Lily's black eye is from Marshall hitting her, they both burst into hysterics.
 * Robin rhapsodizes at length (in the form of a montage) about loving scotch, dogs, The Ghostbusters, etc.
 * Past!Ted steals the blue french horn Robin was admiring during their date from under the restaurant owner's nose, and presents it to Robin while standing in the street under her window.
 * Rube from Dead Like Me had a memorable one when he took George to her own autopsy and compared her corpse to a ruined peach cobbler, establishing his interest in food.
 * Grandma Phyl inspecting her daughter's roof. She meant it when she said she's not gonna lend Joy money if she doesn't inspect the roof herself.
 * Charlie from Life showed his unorthodox method of solving crime his first day back on the job when he asks the other officers if they talked to the dog (who was shot by the suspect).
 * Xena: Warrior Princess wandering through a burnt out village with memories of her past showed her as The Atoner.
 * A unique ECM was Najara. Xena beats up her men then Najara draws her sword. But instead of a battle, she sticks her sword in the ground, takes off her mask and tearfully asks Xena for forgiveness for attacking her.
 * Draco had an impressive one before he got demoted to joke character. He fights to the death a subordinate who failed him while nonchalantly issuing his orders to his lackey.
 * Black Books opens with Bernard ignoring a customer while on the phone to his accountant. When the customer tries to get his attention, he writes "On phone" on a post-it note and sticks it on his forehead. He then proceeds to make fun of the customers admittedly strange request ("I need to know if they're real leather because they have to go with a sofa.") to the point of outright preventing a sale. "Sorry, I need leather bound pounds or they won't go with my wallet". Next, Manny enters searching for The Little Book Of Calm and Bernard proceeds to agitate him as much as he can. Then, to cap the scene off, he kicks everyone out of the shop to close up in the early afternoon and visit his accountant.
 * This scene also establishes Bernards love of books as he refuses to sell the man Charles Dickens books when he is only interested in their appearance.
 * The first dialogue from Friends showed Monica as a hopeless dater, Chandler as a Deadpan Snarker, Phoebe as a Cloudcuckoolander, and Joey's blunt views on relationships.

Joey: C'mon, you're going out with the guy! There's gotta be something wrong with him!

Chandler: Alright Joey, be nice. [to Monica] So does he have a hump? A hump and a hairpiece?

Phoebe: Wait, does he eat chalk? [The others stare, bemused] Just, 'cause, I don't want her to go through what I went through with Carl- oh!

Monica: Okay, everybody relax. This is not even a date. It's just two people going out to dinner and- not having sex.

Chandler: Sounds like a date to me."

"Ross: Hi.
 * Then Ross shows up.

Joey: This guy says "hi" it makes me want to kill myself."


 * Will and Grace: Jack asked Grace if she thought he was gay and she says he's so gay that even dead people know.
 * Misfits gives all five of the main characters their ECM in the introduction of the first episode, while being given a pep talk by their probation worker: Nathan interrupts the speech with some of his trademarked sarcasm and gets into an argument with another young offender; Alisha gets a phone call and answers it, ignoring the probation worker's demands that she hang up; Curtis requests to be transferred to a different group, declaring that he doesn't belong here; Kelly demands to know why Curtis thinks that he's better than the rest of them, and gets offended when the others can't understand her accent; finally, Simon remains completely silent throughout the introduction, looking completely terrified in the process.
 * Wilfred seemed nice enough until he started digging up Ryan's yard.
