I Work Alone

"I don't do partners. You know that, Cap."

- Herschel Biggs, L.A. Noire

Captain Lonerguy has just been offered by an equal to team up. Perhaps it is an out-of-town Cape looking for help on a case that wandered into the Captain's turf. Or his enemy needs help fighting off a power worse than the both of them. If Captain Lonerguy is lucky, it is an equally matched love interest, regardless what side she's on.

In any of these situations, the answer will always be the same. "I work alone."

Cue in audience eyerolling as they must now sit through several scenes of Captain Lonerguy getting his ass handed to him, only to be rescued by said offerer, just so that he can learn An Aesop about the Power of Friendship... or at least strength in numbers. (Even, mind you, if it turns out that he's an Informed Loner—he actually doesn't seem to be alone a lot.)

Occasionally, (and especially if they've had a partner or sidekick die on them) they will strenuously refuse partnering with a Reckless Sidekick, and/or harass new helpers who are competent.

Even after they have learned their lesson, they may have to hear Remember That You Trust Me to keep it going.

-OR-

The Hero really doesn't need other's help and is more Badass for saying so. Cowboy Cops and heroes that actually enjoy their solitude count in this type. A form of Good Is Not Nice. Think Nothing of It and Don't You Dare Pity Me! are common. Of course, saying this line can sometimes be Tempting Fate, and in this particular instance, the usually competent hero might for once find himself in way over his head, and will, often reluctantly, accept the offer of help.

Contrast with I Just Want to Have Friends, True Companions, or You Are Not Alone.

-OR-

The hero knows that they are The Only One who can deal with a problem, and wants to protect everyone else. If they do team up, they're likely to make a Sneaky Departure and go fight the Big Bad alone before it gets ugly.

But you'll be surprised how much more it is just the set up for An Aesop: Loners Are Freaks.

Fridge Logic for those members of the audience that don't get why no one ever trusts Loves My Alter Ego, The Sidekick or The Rival.

Anime and Manga

 * In Ghost in the Shell: Stand Alone Complex, Aoi recites this when he is offered a position in Section 9.
 * Kouji Minamoto in Digimon Frontier for the first five episodes. And then he gets his ass handed to him by Grumblemon in episode 6 but he doesn't accept being part of a team until episode 7 after many fights with The Hero.
 * Phoenix Ikki from Saint Seiya is a textbook case of this. Years after the manga debuted he's still off doing his own thing away.
 * Until his True Companions and specially his little brother Shun are in a pinch, that is. Then you'll have Ikki literally screaming Mind Rape on you.
 * This is Chang Wufei's attitude throughout Gundam Wing, until an encounter with the ZERO System convinces him that teaming up with the other pilots is the best course of action. He goes right back to being a loner in the post-series manga, culminating in Endless Waltz
 * A common theme in sports manga/anime is having a very talented player say this repeteadly and refuse to team-work, often to see him/herself forced to when things go hard. Examples are: Kaede Rukawa from Slam Dunk; Koujiro Hyuuga, Louis Napoleon and  from Captain Tsubasa; Ryoma Echizen and Kaoru Kaidoh (at the beginning) from The Prince of Tennis.
 * Played for Laughs in the case of Takeshi Momoshiro and Ryoma, who try to play doubles and simply cannot do so in the Fudomine arc. Momoshiro gets over that later and becomes a decent doubles player, but Ryoma stays a singles player.
 * In Pandora Hearts Sharon calls Break "Mr. One-Man-Show" because of his tendency to refuse help and go off on his own. He even says himself that he doesn't know how to fight as a team. He's actually pretty good at taking care of business by himself, but due to his, his willingness to rely on others, however slightly, is part of his character development.
 * George Schuyter of Muhyo and Roji's Bureau of Supernatural Investigation, as a result of losing his assistants one after the other, falls into this to the point at which he actively forbids Muhyo and Roji from participating in the fight against Vector and threatens Roji with his sword when he arrives.
 * This was actually the Fatal Flaw of Heartcatch Precure's Yuri Tsukikage. She was so confident in her abilities as Cure Moonlight, that she ignored her partner, Cologne, in finding allies. End result? A massive Curb Stomp Battle leading to Cologne's death and her temporary depowerment.
 * Barnaby holds this stance for the first third or so of Tiger and Bunny, insisting that Kotetsu's only good for getting in the way and being annoying. He changes his tune completely post-defrosting, to the point that he doesn't see any reason to be a Hero unless Kotetsu's there with him.

Comic Books
""The first truth of Batman. It had to be one I don't like to admit. The gunshots left me alone. For years I was alone in the echoing dark of that wait. But something else defined the exact moment Batman was born. The first truth of Batman. The saving grace. I was never alone. I had help.""
 * Nearly every superhero team up starts with one of the parties saying this. Yes, we get it. You are usually alone on your beat. But aren't you failing at school, missing out on dating the cool girl and generally sucking at your normal life because of all the crime-fighting? Why complain now that you have a Sidekick?!
 * This is Batman's favourite phrase, despite him nearly always having at least one sidekick, several other members of the Bat family, and regularly working with the Justice League.
 * For all the Broken Base over the Hush arc, it did a very good job of pointing out that for a supposed loner Batman has a huge surrogate family (from Alfred to the Robins to the JLA to random people from the Silver Age)
 * And now he's formed Batman Inc., following a moment of self-realisation:


 * In the former page quote, Spider-Man and Daredevil are open to the occasional team-up but do work pretty exclusively alone, and attempts to change that generally don't work out. But Wolverine was created for a team book, and therefore almost always works in groups. He doesn't seem to have noticed. In fact, he is currently a member of four different teams.

Film
"Kruger: "I work alone. If anyone comes to you and claims that I sent them... (hands witness a revolver)...use this.""
 * Pee Wee Herman in Pee-wee's Big Adventure: "I'm a loner, Dottie. A Rebel."
 * Every single buddy cop movie that starts with them not being buddies.
 * Pretty much every action adventure cop movie really
 * Used (word for word) in The Incredibles.
 * Also ends up pushing Buddy/Syndrome to his Face Heel Turn. Hell hath no fury like a sidekick scorned.
 * Eraser. Kruger refuses to work with other agents in the Witness Protection program to prevent the possibility of a leak. (It turns out his caution is more than justified).


 * Det. Banks reaction to being assigned a new partner in Spiral: From the Book of Saw

Literature

 * In ''Prisoner of the Horned Helmet, the main character had his entire tribe destroyed when he was 9 or 10 (he doesn't know which). as a result, he swears to never depend on other people, and will not work with anything that has two legs. He does have a pet wolf, though.

Live Action TV
"Wilf: Have you got anyone? The Doctor: No. Traveling alone. I thought it was better, I thought... but I did some things, they went wrong... I need... voice breaks."
 * The Golden Girls: Sophia says this a few times when someone interjects as she's telling a Sicily story.
 * The Doctor in Doctor Who, for a while.
 * After having lost two companions in tragic ways, the Doctor insisted on traveling alone, claiming that he didn't want to have his hearts broken again.
 * Then subverted with End of Time.


 * Abby of NCIS. Her bosses occasionally forced her to take on lab assistants, but she drove them away. After one of them, management decided to leave well enough alone.
 * Burn Notice: Jesse has this problem. He used to be out in the field but got put behind a desk mainly because he didn't work well with others.
 * Dexter: Dexter tells Miguel this in season three and Lumen in season five, but it didn't really work out either time.
 * On The X-Files, Mulder is originally portrayed this way. He hates the fact that he's been partnered with Scully and spends most of the first season alternating between annoying the hell out of her and being nice to her. By season two, though, he doesn't work alone...he just works with Scully. And if he can't work with Scully, he wants to work alone. He doesn't like be partnered with anyone else even for a short time. Scully does the same thing in season 8 when partnered with John Doggett.
 * Buffy the Vampire Slayer Buffy herself is, of course, an Aversion, having the Scoobies for backup, but as far as Slayers go, she is the odd one out. Kendra had No Social Skills to begin with and was suspicious of Willow for even talking to Buffy. She has even isolated herself from her parents, never attended any public school, and while she does have a Watcher, she has never seen him in person. Historically, most Slayers were loners, mostly out of necessity. In one episode where Buffy meets the spirit of Sineya - the very first Slayer - Sineya clearly disapproves of such a habit; Buffy of course, was just as disapproving of Sineya's method, implying such means were outdated - mocking her appearance in the process. Naturally, this leads to a fight, but the two manage to part on - reasonably - good terms.

Toys
"Kopaka: I Work Alone. Pohatu: What, by choice? Or just 'cause nobody else can stand you?"
 * Kopaka says this, word-for-word to Pohatu in Bionicle

Video Games

 * In Final Fantasy IX, Amarant works alone. Naturally he is a "survival of the fittest" kinda player... and eventually learns The Power of Friendship from Zidane, after an object lesson or two.
 * In Command & Conquer Renegade, Havoc outright states that he left the Dead-6 commando unit because he works better alone, and it turns out that he does.
 * Mass Effect 1:
 * Urdnot Wrex points out that he's never been much of one for working in an organized army, as "things get....messy." He works best alone, or "in very small groups." Fortunately, Shepard's team counts as such.
 * Previous to that, the turian Spectre Nihlus declines to accompany Commander Shepard's ground team on the mission in Eden Prime, claiming that he moves faster on his own.
 * In Dissidia Final Fantasy, Squall works alone. The game manages to look at his attitude from a couple of different angles; although the early parts of Squall's story mode seem to set it up as a problem he needs to get over, and he eventually ends up working with Bartz and Zidane, the latter half of his story mode reveals that his choice to travel alone isn't because he doesn't trust the other heroes, but because he prefers to help them by taking on the villains by himself and eliminating at least some of them before they can cause the others problems.
 * More complicated than that, even. He fights alone because he doesn't want the burden of directly protecting people (it's too stressful, and far too easy to make a mistake and get someone killed), and because he trusts his friends to be able to take care of themselves. He knows they're strong and capable, so he doesn't worry about them unless he has to (such as when he saves Zidane and Bartz). He's not opposed to helping others, and in fact he does it without hesitation (running to rescue Bartz with Zidane, for example), but he just finds it's easier to push his limits when he's on his own.
 * To elaborate, the Warrior of Light confronts Squall half-way through his story and calls him out on his apparent lone wolf attitude, mistaking it as a sign of distrust. After their battle, the Warrior of Light realizes that Squall's intentions aren't as selfish as they appear to be, with the latter providing the above-mentioned explanation for his actions.
 * Funnily enough, the Warrior of Light also has shades of this. Not in his attitude, but in his actions, not entirely unlike Squall (who irritably observes the comparison in his Inner Monologue when the Warrior of Light confronts him about his choice to go it alone). What ultimately subverts this, however, is the Warrior of Light's absolute faith in his fellow comrades and Cosmos, which is probably something the latter counted on.
 * Thief; Garrett says it near the end of the second game; there's an Aesop present, and it probably sticks, though he backslides furiously throughout most of the sequel.
 * In both Valkyria Chronicles games, anyone with the "Lone Wolf" trait loses combat effectiveness when in the presence of other allies. Exemplified by Nils Daerden from the first game, who also has no other character to list as a "friend".
 * Herschel Biggs in L.A. Noire before he eventually accepts Cole Phelps.

Web Original

 * In one of Lazy Muffin's flash animations, "James and the Chief," James says, "I work alone, or with my old partner... Which is dead... So this can't be done."
 * Spoofed in Homestar Runner, where Strong Bad's Cowboy Cop alter ego Dangeresque claims "I work alone! 'Cept when I work with Renaldo, which is all the time!"
 * Variant in The Red Panda Adventures: the Red Panda works with a sidekick, but adamantly refuses to work with other superheroes or allow them into his city.

Western Animation

 * In The Batman, Batman is actually the one to suggest to Superman that he should join the Justice League, but Superman is the one to say "I work alone": An intentional flip of their usual interaction. Cue that annoying gnawing at the back of your head (there's a special shampoo for that). Less than 24 hours ago Batman saved Superman from another kryptonite-laden disaster and Supes is right back to the notion that friends don't help in no time. Guess what the rest of the episode was about.

The Batman, Batman the Animated Series, and Justice League have splurged this line about a million times each. In one memorable Justice League moment, Batman uses the fact that he's not an official Justice League member to conduct his own investigation when the official founding members decide to turn themselves in to defuse a tense situation.

Bats has the most extended crime-fighting family in The DCU, save possibly the Teen Titans. Nightwing, Robin, Oracle, Batgirl, Spoiler, Huntress, Alfred, the Outsiders, etc. And yet he's constantly trying to sell himself as a lone-wolf-type. At least sometimes he says, "I work best alone."
 * Codename: Kids Next Door: Parodied by Tommy Gilligan, after he's rejected.
 * The Powerpuff Girls: Parodied by Buttercup, after she adopts a Spawn-like alter ego (she's also hampered by the "only works at night" thing).
 * In Teen Titans Aqualad and Beast Boy exchange this before Aqualad points out Beast Boy is part of a team and Beast Boy retorts that Aqualad "hangs out with a fish dude".
 * Robin had an "I work alone now" period in the flashback episode "Go!" It lasted approximately four minutes.
 * Transformers Animated: "Me Grimlock go with you... but me Grimlock go with you -- alone!"
 * Iron Man expresses this attitude at the start of The Avengers: Earth's Mightiest Heroes, when he fights crime out of a personal ambition to keep his weapons out of enemy hands. Soon, four other superheroes help him defeat Graviton. Iron Man subsequently proposes the formation of a full-time superhero team, to combat threats one hero can not overcome alone.
 * Black Panther enlists five Avengers' assistance in helping him get over the Wakandan border, but insists that he must fight his father's murderer, Man-Ape, by himself. Captain America (comics) tags along with Panther anyway, defending Panther from Man-Ape's warriors, while still allowing him to fight Man-Ape alone.
 * Hawkeye became betrayed by his crimefighting partner, Black Widow, and arrested by SHIELD early on into the series. After he breaks out of jail and clears his name, he decides to chase down Black Widow alone, until The Hulk makes him join the Avengers. Even then, he expresses an initial preference for the other Avengers not to join his personal pursuit.
 * The title character of Ultimate Spider-Man doesn't initially warm up to the thought of assisting four rookie superheroes as part of his SHIELD training.
 * In Trollhunters, all of Jim's predecessors had this policy, reasoning that it was necessary to keep their friends and loved ones safe. It often had disastrous consequences, as their enemies the Gumm-Gumms work as a team and rarely fight fair. Jim is the first Trollhunter to form a team of his own in an attempt to improve the system. Of course, he's also the first Trollhunter who isn't himself a troll.
