Deadpan Snarker/Western Animation

"Twilight: Now tell me, what exactly have you actually seen Zecora do? Rainbow Dash: Well, once a month she comes into Ponyville. Twilight: Ooh. Rarity: Then, she lurks by the stores. Twilight: Oh, my. Fluttershy: And then... she digs at the ground... Twilight: Good gracious."
 * My Little Pony Friendship Is Magic has Twilight Sparkle, Rainbow Dash, and Spike each known for snarky moments, but Twilight Sparkle applies especially well.

"Derpy: (jumping up and down on a storm cloud) I just don't know what went wrong! (electrocutes herself) Rainbow: Yeah, it's a mystery."
 * As mentioned above, Rainbow has her fair share. After Derpy somehow destroys the roof of the Town Hall:

"Twilight: Princess, I'm sorry it hasn't worked out how we wanted, but you have to believe me when I tell you that Nightmare Night is one of the most popular celebrations we have! Luna: Yes. I can tell by all the adoring shrieks of the children as they run away."
 * And more recently, Princess Luna of all ponies.

"Brian: What's it called? Stewie: Susie. Brian: Wow, a song named after a girl. There aren't a million of those already."
 * Daria from Daria is a deadpan snarker and patron of all Snark Knights.
 * See also Jane Lane.
 * See also, on occasion, Trent Lane, Tom Sloane, Jodie Landon, and Michael Jordan MacKenzie (a.k.a. Mack).
 * Brian and Stewie from Family Guy, but especially Brian.

"Brian: I didn't even know I even had a son until today, and besides, it's not like Tracey ever asked for my help. Stewie: Yeah, it seemed like they were all set without you, she's done a fine job creating a child-friendly environmen-ta-re-mi-ooh, buh de buh boo, buh buh buh THPTHPTHPTHPT... Brian slaps Stewie. Stewie: Great parenting."
 * Sometimes Stewie manages to outsnark Brian, though.

"(from "To the Center of the Earth", after Tyrone loses his penny a second time because of Uniqua's invention) Tyrone: See? I could have just walked over to get it. Now it's lost! Professors Uniqua & Pablo: Poppycock! Inventions are always the way! Tyrone: The way to drop my penny."
 * Jen from Downtown is this almost all of the time. She also gets the aforementioned deconstruction, admitting that her constant sarcasm comes from her own insecurities, and that the reason she picks on Alex the most is because he's her best friend.
 * Hovis in Catscratch. THE Trope Exemplifier par excellence.
 * Tyrone from The Backyardigans plays this role both audibly and more often visually. Somehow, despite him not wearing pants, he manages to give the impression he's slouching with his hands stuck in his pockets.

"Cyclonus: (in reference to hearing something moving) Must be the wind. Scourge: There is no wind in space."
 * Spider-Man, especially in the most recent series.
 * Scourge occasionally plays this to Cyclonus in Transformers.

"Katara: If it looks like trouble, we'll leave. Sokka: Yeah, because we always leave before we get into trouble...."
 * Huey Freeman on The Boondocks.
 * Frylock on Aqua Teen Hunger Force. But Master Shake, the resident douche, often doubles as one.
 * Sparks on Sealab 2021.
 * Similarly, Peanut on Harvey Birdman, Attorney at Law.
 * Sokka on Avatar: The Last Airbender initially fit this role like a glove, but as time went on, he developed into actually being the one to make the plans.

"Toph: "It looks just like him to me." Sokka: "Thank you, I worked really... Why did you feel the need to do that?""
 * Toph came in and was able to successfully fulfill, if not surpass him in, this role: "I don't know if you've noticed, but things don't always go so smoothly for our little gang." The creators actually comment on the DVD Commentary that she took the place Sokka had before he shifted to a livelier character from his voice-actor's performance.
 * Especially funny when the two try to out-snark each other. When looking for Appa, Toph comments on Sokka's great drawing skill.

"Guard: What are you doing?! Mai: Saving the jerk who dumped me."
 * Mai:

"Sokka: Ah! Hot! Hot! Katara: Flaming Fire Flakes. Hot. Imagine that."
 * "We lost."
 * Katara occasionally gets the chance to be a wise-ass, usually when Sokka does something stupid.

"Iroh: Ugh! This tea is nothing but hot leaf juice! Zuko: Uncle. That's what all tea is."
 * She also gets like this when Zuko.
 * Even Zuko has his moments, especially in the second season.

"Shego: Okay, let's get Plan Too-Complicated-To-Actually-Work over with. ... Drakken: Would it hurt you to show a little enthusiasm? Shego: Woohoo, extra hoo. Happy? ... Shego: Y'know, for someone who's supposedly a mad genius, I'm not seeing much of the "genius". Dr. Drakken: Keep it up Shego, and you'll see plenty of the "mad". Shego: Ooh, scary man."
 * Almost every character on Total Drama Island (except Lindsay) becomes a Deadpan Snarker over time due to the suffering they go through on a daily basis but Noah, Duncan, Gwen and Leshawna are the most prominent examples.
 * "Woo-hoo, way to throw those murder balls. Go team, go."
 * Shego from Kim Possible. In fact, she considers Drakken to be little more than mocking gold.

"Craig: This is fun. Let's walk for miles through a spooky jungle. It just keeps getting better and better. ... Stan: Dude, what is this place? Random guy: It's like... an unknown valley that time forgot, where everything grows huge. Craig: That's a shock. I decided to follow you, guys, and now I'm in land of a giant's lost world. ... Stan: Let's see what's in there. Craig: Let's see what's in there. That's why you guys get into these situations. Because when you come across a spooky, ancient ruin, you say: "Let's see what's in there.""
 * Fun-fact: Shego wasn't originally planned to be like this, but after the directors realized how much talent her voice actress had in doing the Deadpan Snarker, they changed her whole script.
 * Kim herself also has her moments.
 * In the latter episodes, Stan from South Park has a habit of pinching the bridge of his nose and sigh, when other character does something stupid. He often exclaims "Dude, this is pretty fucked up right here" and, in "Child Abduction is Not Funny", he remarks to Kyle, "Dude, sometimes I think our parents are really stupid," and as they rejoin their families at the conclusion of the episode, "Jesus Christ, dude, they've done some stupid crap before, but, Jesus Christ...".
 * And there's Craig :

"Rattrap: Eh, command's a pain in the tail... especially with this pack of hyenas. You can keep it."
 * By the end of the episode, the four becomes very annoyed with his remarks and tell him things happen you just run with it.
 * Rattrap from Transformers: Beast Wars fits this role perfectly. He is snide, cynical, and sarcastic. He's notable for his frequent use of the phrase "We're all gonna die.", and constantly bickers with Dinobot, and, later, Depth Charge. He is, however, a capable soldier and, if need be, leader, though Jerk with a Heart of Gold may be stretching it.

"Beast Boy: See? [Blackfire] thinks I'm funny. Raven: Statistically, I suppose someone has to. Beast Boy: >:O"
 * Blackarachnia, as the show's resident Dark Action Girl, also qualifies. Especially when dealing with Silverbolt.
 * Slapper, Gas Skunk, and Dark Scream do this a lot to their boss, Sky-Byte, in Transformers: Robots in Disguise.
 * SpongeBob SquarePants
 * Squidward.
 * Sandy and Karen can also come off as this at times.
 * Patrick was one in the earlier episodes.
 * Mandy, from The Grim Adventures of Billy and Mandy. Grim has his moments, too.
 * Raven in Teen Titans, sometimes even to the point of Crowning Moment of Funny:

"(unicorn statuette causes a secret door to open) Raven: Well, that's not suspicious..."
 * And:

"Robin: (about Starfire) I have to find out if she's a threat. Cyborg: (behind his back) More like find out if she'll give him another kiss..."
 * Could be Tall, Dark and Snarky except for the, "tall," part.
 * Cyborg has his moments, too.

"Flash: Fastest man alive. Hawkgirl: Which probably explains why you can't get a date."
 * Hawkgirl from Justice League, who especially had a talent for dishing verbal ownage out on Flash:

"Shade: Lex Luthor? The plot thins."
 * In his few brief appearances, villain Shade has his moments:

"Ben: So... you're my father's receptionist. You know, I mean, in a way, we're sort of related, you and I, like siblings or something, because we both work for my Dad. I mean, you're his receptionist, and I'm his son. So, you know, fantastic, super. Laura: Could you go now?"
 * As does General Wade Eiling, especially after becoming the General. He spends most of his battle against the League's Badass Normals mocking them.
 * Batman and Green Lantern at times, especially in later seasons.
 * Jamie from Megas XLR is, while being a strong coward and womanizer, a decent example of the trope. He is often well aware of and comments on the lunacy and danger of Coop's actions and, sometimes, dialogue. That being said however, he seems to enjoy the destruction Coop's actions brings, so may or may not comment if it doesn't directly affect him.
 * Coop's button of doom would occasionally get in a good one. For example, it was once labeled "Do Something Stupid, Coop".
 * Dougal in The Magic Roundabout, at least in the English language version. Adapter and voice artist Eric Thompson based his portrayal of Dougal on Tony Hancock's radio and TV persona.
 * Lula the talking sword in Dave the Barbarian.
 * Tecna in Winx Club sometimes acts like this.
 * Lawrence Limburger in Biker Mice From Mars.
 * Throttle fits this trope, too.
 * Courage's computer in Courage the Cowardly Dog. Being forced to do research on zombie film directors and methods of exorcising a mattress will do that to anyone, though.
 * Laura in Dr. Katz, Professional Therapist.

"Teen #1: Oh, here comes that cannonball guy. He's cool. Teen #2: Are you being sarcastic, dude? Teen #1: I don't even know anymore..."
 * Norm the Genie from The Fairly Odd Parents.Every sentence is a Deadpan Snark. In the episode "Back to the Norm", Norm teams up with Crocker and constantly Deadpan Snarks him. An example is when Crocker is spazzing, Norm makes him hold a mousse shake thing. When Crocker finishes, Norm says, "That's how I like my shakes. Spazzed, not stirred." From the same episode, Norm asks Crocker, "That thing on your neck...is that your ear?"
 * The Simpsons.
 * Comic Book Guy to the point where he causes a sarcasm detector to self-destruct.
 * Lisa often fills this role occasionally, especially when interacting with the severely less intelligent Bart and Homer. While Lisa fought for things that she believed in the earlier seasons and actual took concern in Homer or Bart's dilemmas, she has been reduced to a pure example of this in the current seasons. "Beware of My Cheating Bart" is a text book example of this.
 * Bart can also act in this role when dealing with Homer.
 * Deconstructed briefly in "Homerpalooza" when Homer gets up on stage to perform his newfound skill of taking cannonballs to the gut:

"Sarcastro: Oh, sure, I'm gonna fight you. (runs away)"
 * Spanky Ham on Drawn Together.
 * The last episode of The Tick (animation) featured superhero-in-training Sarcastro, a man dressed as Fidel Castro who was sarcastic. In fact, being really sarcastic was his only stated superpower, and the only time he got to use it in a heroic fashion (he spent most of the episode snarking at the Tick and the other superhero cadets) was when he faced down the Monster of the Week, a hitman using a suit of Powered Armor:

"D.W.: (while at the Washington Monument) First we were down there looking up here, and now we're up here looking down there. What's the point?"
 * Digeri Dingo from Taz-Mania is by far the most sarcastic character on the show.
 * D. W. from Arthur often switches between being the Deadpan Snarker and a Large Ham.

"Gosalyn: There's something strange about that Bug Master. Darkwing: Yeah, she's in a bug costume threatening a cockroach. I'd call that strange."
 * Darkwing Duck:

"Zoidberg: [runs in] Friends, friends! I have barnacles on my butt! [shows] Hermes: The long search is over."
 * His adopted daughter Gosalyn, as well. Her response on almost being dropped to her death is, "And to think I used to buy tickets for rides like that."
 * Kif Kroker from "Futurama" he despise his captain and his idiotic decisions. He would respond very sarcastically to his captain and sighs a lot.
 * Hermes Conrad, Bureaucrat becomes this in the 2010 season of Futurama For instance, after Fry says he needs a disgusting body to switch with to prove a point to Leela (paraphrased):

"Zap Brannigan: Kif, arrest them! And for once, spare me the weary sigh."
 * Zap, in one rare instance, calls Kif out on his attitude

"Leela: The tracks lead here. Fry: Thanks, eagle eye."
 * Fry has his moments.

"Obi-Wan: You seem a bit on edge. Anakin: There's a good chance that we're about to destroy all life on this planet, including ours and the senator's. So, yes, I'm a bit on edge! Why aren't you? Obi-Wan: (shrugs) I'm better at hiding it."
 * Obi-Wan in Star Wars: The Clone Wars. If anything, he's even deadpan snarkier in the show than he was in the movies.

"Cutman: Almost got him! Protoman: "Almost" only counts in horseshoes, Cutman."
 * Ruby-Spears-version Protoman has a tendency to do this.

"American Soldier: Sir, you may not appreciate our brand of military discipline, however... Baron von Steuben: How can I appreciate what you don't have?"
 * Though quite a few characters engaged in snark on Dungeons and Dragons, it was a particular specialty of Eric's: "Now why didn't I think of that? A game of patty-cake will stop an army of raging orcs any day!"
 * In the show Liberty's Kids, both Sarah and James switch off in playing this role. More often than not, it's James snarking about how stuffy the high society that Sarah was born into is. Though Sarah has been known to throw a great deal of snark right back at him about how infantile Americans in general -- and James specifically -- can be.
 * Baron von Steuben, despite only being in one episode, has his moments:

"Danny: (to Tucker) You can get your own date for the dance like I did. Sam: Does he have to take off his pants and act like a dweeb, or will either one do?"
 * C.A.R. on The Replacements, usually at Dick's expense.
 * Garfield in Garfield and Friends, especially when dealing with someone he finds particularly obnoxious, like Nermal or the Buddy Bears.
 * Sam(antha) Manson on Danny Phantom:

"Jazz: (after accidentally trapping Danny in the Fenton Thermos) Think I should work on my banter? Tucker: Start with your aim."
 * Tucker actually has his moments like this, as well:

"Raggedy Andy: Why don't we just take someone else's pumpkin? Raggedy Ann: You can't make someone happy by making someone else sad! Raggedy Andy: Ever try it?"
 * Nikki Wong on Sixteen.
 * Raggedy Andy in the Chuck Jones Raggedy Ann and Andy shorts.
 * From "The Pumpkin Who Couldn't Smile":

"Doc: (while jailed up in a dungeon) Dear Miss Etiquette. I'm a Galaxy Ranger with a serious problem. I'm about to be executed on a distant planet, and I have no idea about the proper attire. Can you advise me? Signed, Embarrassed."
 * Ulrich of Code Lyoko, usually in response to Odd's latest idiocy or Jérémie's Techno Babble. Yumi can get into this too at times.
 * Dukey from Johnny Test is a mix of a Deadpan Snarker, a voice of reason and a Large Ham.
 * Phaeton from Exo Squad is this. Which is odd, given that he's the Big Bad.
 * June from Ka Blam!!, starting in season 2.
 * Iago from Aladdin. The series also added Haroud and Mozenrath.
 * While all of the main characters on the series indulge from time to time, "Doc" Hartford of the Galaxy Rangers could practically license his snark as a deadly weapon. Even the AI "Tweakers" he created are sarcastic.

"Doyle: Yeah, I was planning on a radio jingle, but I can cancel that."
 * Chloe from Littlest Pet Shop.
 * Batman picks this up in Batman the Brave And The Bold, in full SilverAge glory.
 * Jay Sherman's make-up lady Doris Grossman from The Critic.
 * Candace from Phineas and Ferb. Doofenshmirtz also has his moments.
 * Linda when Candace tries to bust her brothers and when Candace is a Deadpan Snarker herself.
 * Ferb, with empasis on "Deadpan"
 * Roger Doofenshmirtz's secretary Melony
 * Evangelyne from Wakfu, mainly towards Idiot Hero Sadlygrove, penny-pinching Ruel, and towards her charge, Rebellious Princess Amalia. Rubilax, a Talking Weapon, is fully into the Snarky Non-Human Sidekick category.
 * Doyle from The Secret Saturdays. After the family finds out that

"(a girl who humiliated Carver is waving at him at the beach) Carver: She's waving at me? Isn't there a law against that? Tino: (deadpan) Yeah, it's enforced by the Federal Bureau of Waving."
 * His sister is the same. But then, what else can you expect from the voice actress of Shego?
 * Tino Tonitini of The Weekenders.

"Chum Chum: Hey, Kyle! Meet our new friend Yum Yum! We made him out of gum! Kyle: That's the only way you could make a friend."
 * Double D from Ed, Edd 'n' Eddy.
 * Anne and Suzie both have tendencies of this now and then in The Amazing Chan and The Chan Clan, as does Henry when dealing with Stanley's antics.
 * Fanboy and Chum Chum has Lenny and Kyle. The latter even uses the "zing!" on occassion.

"Robin Hood: Hey, that's my tree you're cutting down! King Arthur: Oh? This is your tree? Well, good for you then. Lancelot: Look, I don't want to cause doom and despondency, but I really think we oughtta GET OUT OF HERE!!!!! Lancelot: That's the fountain of youth? I expected it to be more.....impressive."
 * Larry 3000 from Time Squad, which is rather obvious, since he's a Camp Gay Expy of the C-3P0.
 * Philip from Delta State
 * Lancelot and King Arthur in King Arthur's Disasters:

"Pinky: "Egad, Brain, you astonish me!" Brain: "That's a simple task, Pinky.""
 * Hehehehehe. Snark knights.
 * The Brain of Pinky and The Brain, usually in response to Pinky's insanity.

"Dib: "Did you hear that, Gaz? Humans don't have squeedlyspooches!" Gaz: "I've got a squeedlyspooch." Gaz: "Why do you have to have a head?""
 * Tunnel Rat on G.I. Joe: Renegades.
 * Gaz in Invader Zim. Oh so much.

"Rodimus: Don't panic yet. Stay calm until we know what's going on. Then we'll panic."
 * Shep from Horseland.
 * Velma from Scooby Doo Mystery Inc can't seem to help herself
 * Surprisingly, Scooby Doo is one at times.
 * In Transformers Generation 1, Rodimus Prime is prone to this.

"Coconuts: I only wanted to tell you I saw one of those F.O.U's - I mean, C.I.A's, uh, or C.O.D's... Robotnik: Get to the point or your name will be M.U.D."
 * Robotnik, from Adventures of Sonic the Hedgehog.

""He's not only from another planet, he's from a whole different dimension. So naturally, he speaks English.""
 * Raphael is the resident snarker, in the animated Teenage Mutant Ninja Turtles.


 * Mrs. Dink, Porkchop (who can't even talk), and Beebe from Doug
 * T.J., Vince, and Spinelli on Recess
 * King Bob, when he's not being a Large Ham
 * Apparently, Miss Grotke when she needs to be one
 * Sgt. Mike Cosgrove from Freakazoid is probably one of the biggest examples of this, he rarely changes his attitude.
 * Brandy and Margo from Brandy and Mr. Whiskers. Also, Ed has a very dry, sarcastic sense of humor if you pay close attention to his dialogue.
 * Each lead of The Avengers: Earth's Mightiest Heroes has demonstrated snarking capabilities, with Iron Man, The Incredible Hulk, The Wasp, and Hawkeye ranking among those who snark most often.
 * Bloo, Frankie, Jackie Khones, and Fluffer Nutter in Foster's Home for Imaginary Friends
 * Mac becomes one around season three-ish
 * Rocko from Rocko's Modern Life, but only when he's annoyed.
 * Pip in Kerwhizz is a voiceless example, growling in frustration at Ninki's wrong answers.
 * Animaniacs: While all of the Warner siblings could indulge in this a bit, Yakko was the standout.
 * The main characters of WITCH all have their moments, with Irma Lair being the resident queen of snark.
 * Dee Dee from Dexter's Laboratory is a bit of a snarker.
 * Simon in the 80's cartoon version of Alvin and The Chipmunks got deadpan snarkier as the series went on, from occasionally snarky in the first couple of seasons to practically every response being sarcastic.
 * Theodore had his moments as well.
 * Raimundo from Xiaolin Showdown, although not exactly deadpan, is still very snarky.
 * Almost every single character from The Life and Times of Juniper Lee. This show's humor ran on two things: playing with, subverting or deconstructing fantasy tropes and pure grade-A snark. Most prominent in this regard was probably Monroe, the talking, Scotish dog.
