Castor: Let's be honest, Arudin, you're more evil than most of the villains we face. Khagoth: Meaner too. Arudin: I am not evil! I am just... colorfully pragmatic! Khagoth: Whatever. Castor: We're going to bed, Captain Evil.

Just because the main characters are fighting to oust the Big Baddoesn't mean they're heroes... at least, not all of them.
In a team composed of good or morally pH neutral members, there will often be one Token Evil Teammate. Narratively, this character can serve as an entertaining and pragmatic foil to his more strait-laced colleagues, giving Wisdom from the Gutter and might even act to solve difficult moral dilemmas. If the Heroes start putting Honor Before Reason, the Token Evil will often remind them that sometimes unpleasant methods are needed to save the world.
These characters are often Played for Laughs as the Heroic Comedic Sociopath. A lot of the humor they provide is of the Crosses the Line Twice variety, doing obscenely wrong things because it's shocking and unexpected, as well as a form of escapism.
Despite the name, the Token Evil Teammate has a lot of leeway as to his Character Alignment. There are lots of kinds of Anti-Heroes, Anti-Villains and yes, outright Villains who can fill this role. Regardless of character type, the mainstays of this role are usually: snarkiness, jerkiness, ambition, and a tendency to become the Butt Monkey for their behavior. It should also be mentioned that "treachery" was not on that list. The thing with the Token Evil Teammate is that evil does not mean incapable of friendship. While they are usually out for themselves first, they will often have reasons to stay loyal to their team as a whole, or at least individual members.
Sometimes they'll (very) begrudgingly admit that they like their teammates, or at least find them less intolerable than they say, and frequently they find their association either lucrative, entertaining, or even enjoyable. If it's pointed out by somebody that they're not as bad as they make themselves out to be though, they'll generally tell them to shut up, or to take it back. For extra points, this can be done in a very loud, very rude way.
If they do betray their teammates, expect The Captain to tighten the Morality Chain or Restraining Bolt and use various threats like Death Glares to bring them back in line. Why don't they kill him or at least kick him out? Because sometimes you just need the firepower, and they can "do more good than harm" (or at least less harm) on the good guys' side than dead or cut loose. Kind of like controlling a brush fire to good ends.
Some variations include:
They're Only in It for the Money. Or the opportunity to loot, pillage, and plunder. Bribes and financially based threats keep them in line.
B.E.F. (Best Evil Friend): Maybe there's a hero who's a friend or family, and they stick around to help loved ones out of duty. But don't expect them to be too helpful for anybody else.
They have an ulterior motive for joining the heroes, and the heroes' plans will further their own agenda.
Sometimes they're just in it For the Evulz. The hero is on an exciting, heroic quest that will save the world, but it also involves a lot of killing people, and they've got nothing better to do right now. They want to cause chaos and rain down carnage, and this is the best way to do it.
Mayuri Kurotsuchi from Bleach. He isn't part of the Five-Man Band, but he is on their side, for what it's worth... Despite being clearly more evil than many of the villains, Mayuri has to date shown absolutely no interest in switching sides. And not that Soul Society is completely good...
Strangely enough, it also seems that Mayuri only joined Soul Society when Kisuke tempted him with the idea of the possibility of Klingon Promotion, yet he was apparently never The Starscream.
Also, Kenpachi. Despite his adorable lieutenant, he's an Ax CrazyBlood Knight who has no problem physically assaulting his own underlings. He explicitly stated that he didn't care if Ichigo was a friend or enemy; he was powerful, and that was reason enough to try to kill him.
Ikki from Saint Seiya is of the Aloof Big Brother and Loners Are Evil variety. While he was purged of much of his evil in the first tournament arc, his involvement in the service of Athena is usually restricted to making sure his younger brother is safe...and killing off his attackers in brutal ways.
Xellos from Slayers, Calling him a teammate is a bit of a stretch but he does hang around the heroes and they often work together. Considering how powerful he is (one step or two steps below Big Bad depending on the season) it would be hard and dangerous to make him leave. Most of the time he's Affably Evil and dicking around with them for lolz so they tolerate him.
Case in point, Slayers Try when Xelloss actually did betray Lina in order to recruit Valgav. When Lina found out, she merely hit him on the head a few times.
Lina: Xelloss is a monster, so we expect that of him.
Lelouch and Diethard are this for The Black Knights. The former is a rare example of a Token Evil Teammate who is also the Team Leader.
Diethard once again is this along the leader himself when he joins Schneizel. He's the one who justified sacrificing their official leader claiming that baits are not allowed to talk.
In Ouran High School Host Club Kyoya is a subversion of this trope. It is commonly accepted amongst the group that everything he does is for the sake of personal gain and profit, but Haruhi manages to prove otherwise on occasion.
Darker than Black: November 11 plays the Best Evil Friend Variety when working with police officer Kirihara who is one of the few people he'd risk his life for and go out of his way to help. In general, Contractors are supposed to be the Token Evil Teammates of the intelligence agencies which use them for their powers and ability to kill without remorse. The main character of the series, Hei, is a subversion. Contractor-hating human Huang is Hei's Handler and frequently berates him for having qualms about missions and not acting as evil as a Contractor is supposed to be.
In The Prince of Tennis, Hiyoshi Wakashi is sort of the Hyoutei team's token evil teammate (his not so secret aim is to "overthrow" the captain, and he tends to be rather cynical). Also a Sixth Ranger.
Barry the Chopper in Fullmetal Alchemist. While most of the cast are trying to do what's best for the country, Barry just wants to get rid of the Homunculi so he can be free to start killing again.
Also later, Greed.
Faye Valentine of Cowboy Bebop occasionally fits this trope. There are times when she seems to genuinely care about the crew, while other times she's an outright bitch to everybody and seems to only care about herself. She has also stolen bounties that rightfully belonged to another crew-member at least a couple of times as well.
Then again, she's barely a team member in the strict sense. Half the time she's on the Bebop, she's restrained while they check her belongings.
Higurashi no Naku Koro ni may qualify. After many worlds having been traveled through, the characters eventually learn that they must work together as a team in order to break out of the time-cycle of June, 1983. This, however, is after just about all the main characters have had their moments of insanity and complete delusion.
The Keroro Platoon in Keroro Gunsou has Sergeant Major Kururu, a Jerk AssMad Scientist with a fondness for tormenting his teammates, and pretty much everyone he comes in contact with. One of the earliest excuses for the frogs not making progress is that Kururu won't invent anything useful unless it strikes him as interesting at the time.
And the frogs themselves are, at least in theory, a Token Evil Team to the Hinata household, seeing as they're supposed to be taking over the world. They don't really ever make much progress, though.
Katekyo Hitman Reborn!: Mukuro Rokudo has explicitly stated that the only reason he is working with Tsuna and his group is so that he can eventually steal Tsuna's body. In a similar vein, Mukuro's counterpart from the first generation of Guardians, Daemon Spade, was stated to be a backstabber.
Despite what some fangirls will tell you and despite the fact he's almost always accompanied by an adorable bird pet, Kyoya Hibari isn't a much better person than Mukuro and Daemon. However, the first Cloud Guardian, Alaude, was said to be similar to him in his younger days but he got better (despite remaining cold and aloof), so it's possible Hibari might grow up as a decent person. As it stands, however, Kyoya isnotone.
Agon from Eyeshield 21 becomes this in the World Cup arc. He only joined Team Japan because he wanted to win the three million dollars and isn't above threatening his own teammates to do so.
There have been several Token Evil Teammates throughout the various Gantz rosters, but the two that stick out the most are Nishi and Izumi. Nishi is mostly a nihilistic jerkass whose actions are usually at least understandable, whereas Izumi is far more damaging.
In Flame of Recca, Recca has control over 7 dragons, all of them are more or less amiable (One of them is his Bumbling Dad), except one certain dragon named Setsuna. He hates Recca, wants nothing more than to kill him and be free, and resume his old life... as a sociopath mass-murderer. Recca still beats him down to submission.
Arlong in One Piece was this in the Sun Pirates. While there were other unsavory characters in that group, Arlong would be the first one to suggest violent terrorism towards humans. He even wanted to kill a slave just for being human.
At Sabaody, The Supernovas Eustass Kidd and Trafalgar Law briefly teamed up with Luffy Kidd seemed to be this at the time, with his evil apparently nothing more than an Informed Ability. it wasn't. More recently Law made a return as an ally and seems to have shades of this, being a much darker character than any of the Straw hats, and acting as a foil for their playfulness.
Nguyen from the Area 88 manga and OVA. Even by mercenary standards, he's an unhinged sadist.
History's Strongest Disciple Kenichi: The Shinpaku Alliance arguably has one as the leader, Nijima. Various other characters in their orbit could also be considered as such depending on how strictly you ascribe the term "teammate" to them. These can include three members of YOMI; Tanimoto Natsu, Rachael Stanley and Kushinada Chikage. All of them have friendly dealings with Kenichi and the rest of the Shinpaku Alliance even if they have yet to renounce their ties to YOMI.
Weevil/Haga and Rex/Ryuzaki served as this in the first third of the anime's Doma arc, up until joining Doma.
Wolfwood, while not a truly "evil" character, actually serves as this in Trigun Maximum. Although in the anime the revelation that he was working with the Gung-Ho Guns was saved until late in its run to make it a surprise twist, the manga on the other hand revealed this almost immediately after his first appearance. Although he is helping Vash against the other GHG members, he is actually following orders to keep him alive no matter what the cost (even if it involves killing the rest of the GHG). It's only much later (after most of the other 'Guns have been killed) does he completely abandon the antagonists' side and fully start working with Vash.
Deconstructed later on in the story arc, in which Urza takes a team of the multiverse's most powerful planeswalkers to Phyrexia to perform a raid on the plane in his efforts to destroy Yawgmoth...including the Evil Sorceror Tevesh Szat, who had posed issues to Dominaria in the past. As it turns out, he ends up turning on his comrades and slaughtering a few of them. And Urza was fully expecting this to happen - he hired Szat just because he had hoped he would betray the team so that he'd have an excuse to siphon out the souls of Tevesh Szat and his victims and use them as bombs. Really, by this point the only thing keeping Urza anywhere close to the side of good was the fact that he was doing this in order to kill someone a hundred times worse than he was.
The X-Men like this. Sabertooth has been on the team at least twice (though one of those times it was a situation where they didn't want to kill him, but didn't trust anyone else to deal with him - he was an involuntary teammate).
Juggernaut, Magneto, Mystique... at least Juggernaut and Magneto went to genuine Heel Face Turns.
Wolverine is usually the Token Anti-Heroic teammate for whatever team he's on, though the lines can blur when he becomes a Darker and Edgier anti-hero. Particularly striking examples are when he's the only member of the Avengers who's willing to kill, much like he was in the early days of his X-Men tenure.
Iron Man actually lampshades the need for such a teammate for his Mighty Avengers line up when deciding to recruit Ares (the actual greek god of war/construction worker in the marvel universe). Tony specifically mentions Wolverine as an example of the kind of teammate they need for this role.
The Young Avengers has their 'Team Sociopath,' Tommy Shepard AKA Speed.
Also X-related, Magik from the New Mutants spent her whole time on the team battling her demonic side, but that didn't stop her from being the first to suggest killing some bad guys. When the other kids would tell her they don't kill, she would compromise by sending the villain to Hell. Not quite sure how that was considered better.
An adult version of Magik from an alternate universe filled this role for a while in Exiles.
The Comedian of Watchmen, who even went as far as to try to rape one of the other members of the team. Whether or not the other members are any better than the criminals they go after is debatable (excepting both Nite Owls, whose biggest flaw in both cases is being largely ineffective), but The Comedian is definitely the worst of them and seems to thrive on torturing and killing people. He even kills a pregnant woman (carrying his own child!) back in Vietnam.
And in X-Statix, you had a bizarre inversion-subversion mix with Arnie Lundberg, the Mysterious Fan Boy, as a token good teammate in a team made up of people who don't care about morality at all. Arnie is an idealistic kid who believes being a hero is its own reward, and as such is easily the most moral member of the team ever. He's also easily the one who has inspired the most fear, having terrorized his hometown with his Reality Warper powers with a total lack of remorse. Eventually friend of the team Lacuna takes it upon herself to kill him before he can cause any more harm.
Though Hsu and Chan aren't exactly the most moral duo, Gila Mobster fits this role perfectly in their misadventures, using methods which the titular brothers insist that he keep to himself and carrying out several odd jobs for local mafias and corporations which actually leads to him trying to murder Hsu in Brand Loyalty.
Loki "Trust me! I'm the God of Lies!" Laufeysson in the Danish comic Valhalla, based on Norse Mythology. Mostly saved from being hateful by being comically inept.
When the six Infinity Gems were split after The Infinity Gauntlet, they were split among five known members of Adam Warlock's Infinity Watch, with the Reality Gem given to an unknown sixth member, eventually revealed to be an extremely potent version of this trope: Thanos - not only an enemy of Adam Warlock, but the one who Adam had taken the Gauntlet from. It's unknown if Thanos ever actually tried using it, though.
He once used it to temporarily revive Captain Marvel from the dead, who he then informs that he contemplated using the Gem to make Death love him. Captain Marvel then speculates that the reason he was revived at all was so that he could talk Thanos out of such a plan, Thanos knowing it was a bad idea to begin with and subconsciously providing the means to stop himself.
There tends to be at least one during in Teen Titans during any time. Rose Wilson (Revenger) and Damian Wayne (Robin) were the most recent
Karla Soften AKA Moonstone was this after the Thunderbolts turned good, having turned on Zemo out of her own self-interest and never quite making the jump to being a good person.
Doctor Doom becoming a member of the Future Foundation is the very epitome of this trope.
Green Lantern now features the New Guardians, a team comprised of one member from each of the Corps, and Arkillo of the Sinestro Corps is this trope for the team.
Blackblood of ABC Warriors was a robot literally designed to be evil, and as such has turned on his teammates on several occasions. He's quite openly said that he'd like to kill Hammerstein, the leader.
Ladytron in various incarnations of Wild CATS. An extremely powerful and volatile cyborg, she was mostly recruited onto the team because the alternative is not having her on your side. It took weeks of holographic simulations to break her down into a somewhat manageable, not-so-murderous state, but she's still only "good" in name and because her teammates force her to be.
Darkhell from Les Légendaires briefly filled this role when he agreed to become The Champion for the Guardian with his Good Twin Elysio during their crusade against Anathos; the only reason he agreed to do this was because he was given more power, brought back to life with a new body and had to kill his Arch-Enemies the Legendaries as the main mission due to them being candidates to become the hosts for Anathos' reincarnation. Ironically, he and Elysio both end up doing an Heroic Sacrifice to save the Legendaries.
Dungeon Keeper Ami has Jadeite as both a straight example, and as something of an inversion. As part of his Shades of Grey theme, he learns empathy and gains a more uplifting world outlook due to Mercury's influence. Regardless, he is by far the most straightforward, pragmatic, and blunt of Ami's advisors in regards to her goals and resorts to dubious methods at times if the situation warrents it.
Ike of the Pokemon fanfic Pedestal first met the protagonists by attacking the narrator and ferociously declaring that he would rip them to shreds. After joining the party, he still plans to murder Namnar after a certain period of time, and after years of working with Des and Carlita, still comes very close to attacking them. Eventually, Ike morphs into a Sour Supporter.
Makuhita of the fanfic The Retelling Of Pokemon Colosseum is DEFINITLEY an example.
The Team mage in "Dragon Age: Wardens" not only could care less about his fellow wardens and often sits back and lets them struggle...he actively murders other soldiers on a whim or turns them into bombs regardless of if they were dying or not.
Mana Ryougi is this to The Emiya Clan. She, like her mother, had a very skewed morality, but unlike her mother, she mostly works as a contract assassin, trading blood for money with few restrictions. The others have mixed feelings about her. Kiri and Aleksi have issues with her lack of loyalty to any particular cause and her willingness to interfere with them if she is paid to. On the other hand, Touma idolizes and respects her for her efficiency, iron will, and dedication to standards that she hammered into him when she trained him as an assassin. Everyone else is somewhere in between.
In That Epic Plan Beyond Birthday is this for the Kira Taskforce-at least in theory. In practice he's Light's Dragon.
Mittens from Bolt is an example only in the titular dog's mind, but she sure plays the role to its hilt.
Films — Live Action
Ed Harris' character in National Treasure 2
The Indiana Jones series features a lot of Evil Teammates. Even after it comes to light that Allison Doody's with the bad guys, there's still some teamwork between her and both Indy and his father. It's pretty well established that Ray Winstone's character in the fourth Indiana Jones movie, but Indy takes him along for the ride anyways.
Sorceress: I am not evil! I'm Chaotic Neutral! Everyone:(deadpan) You are evil Paladin:...and a whore.
As it happens, Paladins (in Dungeons & Dragons) have the special ability to Detect Evil and are forbidden from associating with evil people, so the paladin may have been violating his oaths by adventuring with the Sorceress.
Archer Maggott from The Dirty Dozen is a bigoted, psychotic, woman-hating, murdering rapist, and Major Reisman knows it. But given that Maggott is also a trained G.I., and the operation needs all the help it can get, Reisman retains his services. Maggott doesn't mind volunteering for the mission once he realizes it could save him from the hangman. Ultimately he goes completely insane, attempts to kill his teammates, and almost sabotages the entire operation, but for a while at least he was a warm body with a machine gun.
Victor Franko, being a member of the Mafia (and a convicted murderer), having no respect for authority, and making several attempts to escape and/or undermine Reisman's authority, might also count. He got better, though.
The Sweedish Chef in the 2011 version of The Muppets. He finds a pile of mouldy talking vegetables in a fridge who've been waiting for him to come back and let them out for years. He promptly burns them to death, giving him a higher body count than most Disney villains.
In Blade 2, it's more a matter of "token good teammate". The film is an Enemy Mine scenario in which we already know that every one of Blade's collaborators except Whistler and Scud is evil and it's question of when rather than if they'll betray him. As it turns out, Scud was also planning to betray him from the start.
Although he's not evil, Mundungus Fletcher from Harry Potter is a criminal and a con artist. He was disliked by the other members of the Order of the Phoenix because he was considered untrustworthy. He did eventually end up stealing from a member of the Order, and unwittingly giving a horcrux over to Dolores Umbridge.
He also abandoned Mad-Eye Moody during battle, possibly causing the latter's death.
Dr. Hix's presence at all is explained as by having an official department for dark wizards, they have an excuse to deal with unofficial dark wizards. With Fireballs.
Hix was technically introduced in Making Money, but then he was a minor functionary, and since he wasn't on the University Council, he A - was not allowed to do anything evil, and B - still spelled his name "Hicks".
Arguably, in the Dresden Files books, the gangster Johnny Marcone is this. Although he runs a criminal empire, and has no qualms about killing most people in cold blood, he is practical, Dangerously Genre Savvy and often works with Harry, in one case saving his life. Given that he Wouldn't Hurt a Child, and keeps his word, Harry has a hard time seeing him as a Complete Monster. And, we see in "Changes" he goes much further funding an organization devoted to defending Chicago
By about halfway through the series, Rachel from Animorphs was getting there. It's heavily implied that she started out with nothing but a tendency towards pragmatism and ruthlessness that was slightly more pronounced than the other team members. But the group kept needing someone to do the smart thing, instead of the right thing, and Rachel kept volunteering, and it became a part of her character. As she put it in a later book, "They needed me to be the bad guy. And I needed them to be the good guys. Because if they were good guys, and I was on their side, then that meant that I was a good guy too. Even if I was different."
Mogget the white cat/albino dwarf from Garth Nix's Old Kingdom Trilogy, actually a powerful Free Magic elemental that attempts to kill the nearest Abhorsen whenever he is freed from his binding. He frequently travels with and helps the protagonists in his bound form (though sometimes, especially during the last book, his motives and loyalties seem questionable). Still, he does come through for the good guys in the end when he lends much-needed assistance to bind Orannis, because he just loves the living world too much.
In the Druid of Shannara, Pe Ell plays this to Quickening's group, specifically inducted into the group because he was evil enough to bring about Quickening's necessary death.
By Freedom, Loki/Gragg realises that he has become this, since the Darknet community has largely evolved beyond its early disaffected-and-misfits days to encompass many normal people and has little need of sociopathic hatchetmen like himself.
Lokor in Star Trek: Klingon Empire. Of all the Klingons who consistently follow Klag's authority and have yet to pull a Face Heel Turn, Lokor is basically the one guy who has the fewest scruples in screwing people over to get them to toe the line and not buck the system, and most of his methods are disturbing in their effectiveness. On the other hand, he's also unbelievably useful and indispensable to the point that Klag trusts him implicitly.
In the tenth Haruhi Suzumiya novel, Kimidori revives Ax Crazy Ryoko Asakura because "Your potential usefulness was marginally greater than the threat you present."
In A Song of Ice and Fire, Robb Stark has one in the form of the cruel and ruthless Roose Bolton, who's more than willing to use monsters like the Brave Companions and allows his soldiers to Rape, Pillage, and Burn freely. He even goes as far as to turn against Robb purely out of opportunism at the Red Wedding, with his forces joining the massacre of his former allies and him personally killing his former king.
In the first N.E.R.D.S. book, Jackson Jones sort of counts, considering he was against the nerds before getting his braces, and being the only on a team of nerds to have been popular at one point.
More of a "token pragmatist", Tyr in Andromeda was both invaluable and tried to sell out the ship/crew at least once per episode. It helps that Nietzschian pragmatism can be used to justify any action. Even Beka Valentine, a Han Solo-esque rogue, had far more loyalty and backbone.
Oddly enough, the show House features its main character Dr. Gregory House as one of these. Whatever his actual moral alignment may be, he's a brilliant diagnostician, but his demeanor is that of a snarky jerkass with an addiction to painkillers, and he's made it quite clear that solving complicated medical mysteries is pretty much just a fun game for him. Failing to save a patient's life is usually more of a blow to his ego than a source of sorrow.
This is really a case of Villain Decay. Early episodes showed him to be much more malevolent and the show itself was much more serious. It quickly devolved into slapstick. Also, in the earlier episodes Smith's unquestionably necessary skills as a doctor prevented the Robinsons from simply flushing him out the airlock, whereas in the later episodes he contributes nothing to the team and all he ever does is get in the way with his self-serving schemes.
Major Charles Winchester of M* A* S* H. He's not above trying to get something out of his forced residence at the 4077th (especially if it's at the expense of his tent mates), but he does do his best to take care of the patients. Turns into a Jerk with a Heart of Gold later in the series.
In Farscape, everyone is quite morally ambiguous—especially by the final season. However, in that season, Scorpius definitely qualifies. Earlier on, there's Rygel, who constantly tries to sell out and undermine the rest of the team and unashamedly jumps on any opportunity for profit. Chiana plays this part in early appearances, first (implicitly) mirdering her custodian and then torching the captain of the Gammak base to a crisp.
Tom Zarek of the re-imagined Battlestar Galactica likes to portray himself as a staunch defender of the little guy, who had to resort to extreme measures to try to empower his disenfranchised people, and yet ordered things like bombing convention centers, tried to have the president assassinated when there were less than 50'000 known survivors of humanity, ran an illegal black market which had previously included the exploitation of children, and had sold his position numerous times. While he does seem genuine in at least some of his outspokenness, the fact that he could be blackmailed with this information says something about his character.
And then, well... let's say season 4 gets a lot more definite on the subject of his character.
Sawyer pretty much filled this role in the first season, or at least he was the token Jerk Ass.
Spike on Buffy the Vampire Slayer has been nearly every level of this. He started on the road with the one time team up variety. When he got a chip put in his head to prevent him from hurting humans, he joined the Scoobies as the Token Evil Teammate, since killing demons was the only way he could get his kicks. This didn't stop him from working with Adam or being a general asshole - they only kept him around because he was occasionally useful and they didn't want to kill someone physically incapable of fighting back.
Faith believes that her Slayer powers give her the right to steal and generally run amok (eventually leading to the accidental death of a person). She soon goes from Token Evil Teammate to straight villain and The Dragon for Mayor Wilkins.
Anya's pining for her lost vengeance demon powers and lack of sympathy for humans qualified her as an Evil Teammate to begin with. Soon enough, though, she was just as goody-goody as the rest of the group, just odd.
He's an exiled Cardassian who was an agent of the Obsidian Order, that race's secret police. He is quite the magnificent bastard, possessing skills like interrogation, spying, hacking, blackmailing and of course, assassination.
He's not a bad tailor, either.
In Star Trek: Deep Space Nine, Gul Dukat works with the crew of Deep Space Nine and forms a mutual trust with Sisko to eliminate a greater evil far more often than Sisko should trust him. At some point in the series, the two become mortal enemies.
How I Met Your Mother has Barney Stinson, the embodiment of this trope. A Ladykiller In LoveThe Casanova to the extreme who works for Mega Corp, which is implied to have all sorts of really evil things going on with North Korea and even somehow contaminating the drinking water in Lisbon for some reason? Yeah, pretty evil.
The other characters occasionally wonder why they even hang out with Barney when he's being exceptionally assholish. The reason, of course, is that he's like family to them, and no matter how horrible he acts, they can't bear to abandon him, as Ted realized in season 3, and Marshall in season 6.
Chuck Bass is the Token Evil Teammate of Gossip Girl's Non-Judging Breakfast Club. True he's mellowed, but a guy who's attempted to rape another team member definitely counts as evil.
The Sarah Connor Chronicles: Reprogrammed Terminators like Cameron, Weaver and those employed by the Resistance fit this category to a T. Cold, logical, unstoppable and brutally pragmatic (Cameron would kill anyone she even suspects of being a threat, and Weaver slaughtered an entire warehouse of people for working for Skynet when John Henry intercepts an unsecure communication) — be glad they're on our side. Of course, "Sometimes they go bad. No-one knows why."
Possibly Tom Price in the 2008 remake of the BBC drama Survivors, only his position as the Big Guy of The Family has kept the other survivors from killing or permanently banishing him, and even then, only barely.
On Stargate Atlantis, Todd the Wraith occasionally allies with Atlantis versus Replicators, Genii, other Wraith clans etc.
Stargate Universe's Dr. Rush is the only person smart enough to help out his crew mates most of the time. Which he stranded them on in the first place. He also is arrogant, doesn't care about what happens to anyone else on the ship and by now completely insane.
As referenced in the Andromeda example above, Avon from Blake's 7 might just be the prototypical sci-fi evil teammate: snarky, argumentative, cynical, and in favor of self-preservation over doing the right thing. He repeatedly claims that he’d sell out the rest of the crew in a heartbeat if it was to his benefit. It’s not clear how much of his attitude is a bluff, but he certainly is more… morally pragmatic than Blake is. Avon is a bit of an odd example because after season two, he’s the protagonist.
Arguably, the only thing that stops him from leaving the Liberator is the Liberator In the final episode of season 2, he tells Blake he's done with Blake's revolution and will only help if he is given Liberator. Blake agrees and Avon is content enough to follow Blake on what could easily be a suicide mission.
Being an Expy of Dr Smith, Brad Spitfire from French-Canadian science-fiction comedy Dans une galaxie près de chez vous fits this trope completely: cowardly, greedy, power-hungry, Nazi-loving and all-in-all hated by every other members, the only reason hasn't been Thrown Out The Air Lock by now is because he is the only one scientist on board, and his skill are greatly needed.
H.G. Wells on Warehouse13 goes from pure villain to a member of the team. Artie is certain she'll betray them at any moment.
And as it stands he was right. She eventually betrays the group to wield one of the most powerful and destructive artifacts there is that nearly causes a mass earthquake capable of wiping out all life on earth after (in her eyes) seeing the future world decay so horribly over the years from her time.
Also, in Serenity, after River gets triggered and Mal still keeps her on the ship, Jayne tries to kill her in order to get the Alliance off their backs.
However, Jayne definitely shows that he has good in him. Whether it be his shame of betraying Simon and River after Mal was about to throw him out of the airlock (it wasn't just fear but legitimate shame), or him eventually advocating in favor of doing the right thing near the end of Serenity.
Guerrero of Human Target. He is intensely loyal to Chance, but that seems to be about it as far as morals go. Threats, torture, murder? Check, check and check.
He doesn't look like much, but his name is enough to cause an experienced thief to wet her panties.
Faye from the The Secret Circle is a subversion: she has all the surface traits, but doesn't want to hurt anyone and is scared of losing control of her powers. Jake, on the other hand...
Arguably Damon from The Vampire Diaries. He's not even LIKED by most of the team, and the main reasons they keep him around is that he's Stefan's brother, it means they know where he is and what he's and will lend a hand if it serves his purposes. In Season One, they let him stick around because he was too strong to fight. In Season Two he's more of a team player, but maybe that's because Bonnie has proven that she could (and almost DID) kill him if angry enough with him.
Elijah joins them in Season 2 despite being rather antagonistic earlier in the season.
Cara on Legend of the Seeker might qualify as this after her Heel Face Turn. Although she's extremely loyal to Richard and eventually admits, albeit begrudgingly, that she cares a lot about her teammates, she seems to really enjoy killing and torture, and finds the other characters' displays of love and affection nauseating.
Similar to House, the main character (or one of them) in White Collar is more or less this: Neal Caffrey is a Boxed Crook working with the FBI in exchange for not being in prison. Subverted inasmuch as Neal shows signs of reform—to say nothing of the fact that, as a good-natured forger and con artist, Caffrey wasn't terribly evil to start with.
Nathan from Misfits isn't quite evil, but he's a bullying, self-obsessed, borderline-sociopathicTed Baxter of epic proportions, who is regularly suggested to have some kind of undiagnosed mental illness.
"This is why people kill you."
Hobbes from V is a mercenary wanted by the FBI who is forced to join the Fifth Column after the Visitors frame him for a crime he didn't commit... which is not to say that he hasn't also committed other crimes which were just as bad or worse. In the V: the Final Battle mini-series from the 80's, Michael Ironside portrays merc Ham Tyler, whose was initially distrusted by the Resistance as being a warmonger.
Sam in iCarly. If the plot requires anything that isn't lawful, Sam will suggest it and carry it out.
Santana in Glee has increasingly become this in the second season. Quinn can flip in and out of this role.
From time to time Pierce Hawthorne on Community fills this role.
Chang sometimes does too. For example when Pierce endangered Annie's anti-drug play it was Chang who saved it.
Supernatural dances around this a lot. Season 3 gave us Bela, who while pretty evil wasn't exactly a team player, and Ruby, who turned out to actually be The Mole. Finally, however, season 5 gave us Crowley, who, while still perfectly willing to kill innocent people and send souls to hell, proved to be a valuable member of Team Free Will.
Luther has Alice Morgan, at least after the finale of the first series. Even though Luther's a policeman and she's an unrepentant murderer and sociopath, the two have an understanding and friendship of sorts and are perfectly willing to help each other with their various problems.
Ingrid of Young Dracula is this whenever she helps Vlad, which isn't often.
Myths & Religion
In The Bible, Joab son of Zeruiah acts this way for David, ostensibly commander of David's army but doing evil things like disobeying David to kill David's son Absalom (who'd just staged a failed coup) and his intended replacement Amasa. Unlike many examples of the type, he does get killed for it once he outlives his usefulness (and supports a rival of the legitimate heir to the throne).
In some interpretations, Judas followed Jesus more out of personal ambition than true belief, and he sold Jesus out when things weren't quite going like he expected.
Loki seems to fill this role for the Norse Gods sometimes. Not the rest of them are really paragons of virtue.
A Token Evil Teammate is a common occurrence in any group of players, regardless of system or original intent of the campaign. This is frequently a cause of friction inside the group, and certainly the cause of much interesting character development and actual role-playing. Why is the lawful good paladin working with Nazis? Let's find out!
Often goes too far and gives you one Token Good Player instead.
In the original Dungeons & Dragons adventure The Keep on the Borderlands, there are opportunities for NPCs to join the party, and some of them are of evil alignment.
In the same vein, Temple Of Elemental Evil (or at least Troika's computer remake) features many joinables, the majority of them are evil aligned (a few good joinables and several neutrals exist though).
In the original AD&D, the Assassin is the most likely candidate for this role, as the class in question requires an evil alignment.
Black Robe Wizards can fill this role in a Dragonlance game.
Kreia in KotOR 2 if the player character is light-sided, as she believes in balance above all else, and so gives "evil" advice when players do good things.
There are others who start out evil, and can be redeemed, in KOTOR II - G0-T0 comes to mind.
Star Wars: The Old Republic: The Jedi Knight has Lord Scourge as one of his/her companions, he is a Sith Lord who is happens to be the Sith Emperor's personal body guard. He sides with the Jedi because he saw that he/she would be the one who will defeat the emperor. It should be noted that in the past he aided Revan and the Exile in taking down the Emperor, but betrayed them when he had a vision that they would fail, and the Jedi Knight would be the one who will kill the Emperor.
One-of-Many, an undead Hive Mind, could possibly be this in the expansion Mask of the Betrayer, but this would largely be averted (provided the player doesn't choose to make a sudden Heel Face Turn) by the fact that the PC would have to make a consciously evil choice to get him/it/them/? instead of Okku (the corresponding good character).
Leaving aside the fact that Storm of Zehir lets you hand-craft your own party, T.E.T. and all if you so desire, among the cohorts are the deep gnome wizard Chir Darkflame (Chaotic Evil), the aasimar Shadow Thief Belueth the Calm (Neutral Evil), and the half-drow warlock Quarrel (Chaotic Evil).
Nix is more of an Anti-Villain. While she is willing to kill it is more due to her traumatic experience and wanting to get revenge. After the plot twist, she is willing to sacrifice her life to stop the Beast who will destroy everything, compared to her counterpart Lucy, who joins with the Beast to save herself.
Not really noble goals fighting the Beast. When you fight her in the Evil ending she basically says that she's only fighting the Beast because of desire for vengeance and because she doesn't want to be part of a crowd of Conduits.
The Silencer, of the Crusader series. An unusual example, given that he is the player character.
Warlocks and Death Knights seem to serve this role in World of Warcraft. Warlocks fit the role very loosely, since they indeed horribly kill their enemies and steal their souls, but their class quest chain is dedicated to resisting the Burning Legion's influence and not succumbing to evil.
As well as the entire faction of the Forsaken, who are not saints.
And Death Knights feed by the very act of killing, which is perfectly suited to the role of adventurer..and thus not really fitting the trope very well. All of what made the DK class "evil" was because they were compelled to do Arthas' will, which disappears after the Knights of the Ebon Blade rebel.
On the other hand, many of the Knights of the Ebon Blade take questionable approaches to fighting the Scourge, from being willing to fire even while risking hitting web-wrapped "human shields" to destroying the soul of an enemy commander.
In Wrath of the Lich King, Malygos, leader of the Blue Dragonflight, has gone insane and is leading his dragonflight in an attempt to destroy the world due to what he sees as overuse and misuse of magic by mortals. The Wyrmrest Accord is an alliance of the other four dragonflights of Azeroth against the blues. The black dragonflight is part of the alliance. The leader of the black dragonflight also wants to destroy the world, in his case because he was corrupted by Eldritch Abominations, and in fact he would try to in the very next expansion, but he wasn't around during the events of Wrath of the Lich King. So the blacks, while evil in general, weren't making a concerted effort to blow things up when the blues were.
Korgan Bloodaxe in Baldur's Gate 2. His Chaotic Evilness is to the point where some people LEAVE YOUR PARTY if the right dialogue goes down. He is also immensely badass — just look at his name.
To be specific, Korgan will chase Aerie out of the party by verbally abusing her. If you're playing the expansion, however, Aerie instead starts verbally insulting him right back — at which point Korgan reveals it was a Secret Test of Character to see if she was able to stand up for herself or not — and now that she's proven that she does, he no longer has a problem with her.
The Baldur's Gate series is pretty rich in villainous PCs. In Throne of Bhaal, this extends all the way up to bringing the villain of the first game Back from the Dead as a recruitable party member!
We also have Edwin, snarky Gender Bender wizard who talks to himself frequently about fireballing the party as they sleep. He also hated Dynaheir, Minsc's partner in BG 1; in BG 2 she's dead, and he mocks Minsc about it, showing zero sympathy. He seems to be driven by ambition and thinks the PC is a quick route to power - and despite mutinous mutterings, Edwin is one of the most loyal NPCs in the game, and it is perfectly possible to go through the game with a Good party, high Reputation, good deeds left and right, and all Edwin will do is some amusing snarking about it.
Myron from Fallout 2, who's evil extends to potentially drugging and raping a female PC with a very low intelligence score. He is intended, to all appearances, to be a character that nobody will like (being annoying, beyond the Moral Event Horizon, AND bad in combat), and which everyone will only use for his abilities. He's easy to keep in line just with threats, since he's so pathetically weak in every way. Even if you let him live, he gets murdered in some back alley in the epilogue, regardless of your actions. Even the writers couldn't stand him.
Jericho from Fallout 3 was formerly part of the Raiders, who are notorious murderers, rapists, sadists and possibly cannibals. Though he nominally works as a part-time protector for the settlement of Megaton, he usually ends up getting drunk off his ass and reputedly attempted to rape one of the local residents. A player with bad karma (and 1000 caps) can convince him to come out of retirement and become a companion.
Joshua Graham was originally supposed to be one of these in Fallout Van Buren, where he was known as The Hanged Man. However, due to the fact that J.E. Sawyer decided that this did not make for an interesting character, Graham appears in Fallout New Vegas as a deeply conflicted yet incredibly brutal Atoner. Also, Ulysses was originally meant to be a Legion-affiliated companion (and in the game was a former Legion spy/scout) but was cut from the game proper, though he becomes the central figure of the Lonesome Road DLC.
In DLC Dead Money, Dean Domino plays this role, being practically responsible for everything that went wrong with the Sierra Madre due to being jealous of the creator. If the player gets on his bad side, he will try to kill you off near the end.
Arguably Kain in Dissidia 012, who attempts to kill all of his teammates, and does not participate in the final act of the 012 cycle (with Lightning, Tifa, Yuna, Vaan and Laguna, all of whom (except Lightning) are very optimistic and kind-hearted characters).
Ceville from the game Ceville is one. He, in fact, is the disposed former tyrant of the kingdom - your first act while playing as him is sending the Three Little Pigs and the Big Bad Wolf into slave labor and stealing all their possessions. He never really changes his personality or attitude during the entire game. The only real reason he tolerates Lilly is because she's useful in his quest to get revenge and (sorta) take back his kingdom. Despite being a stereotypical evil tyrant though, Ceville shows quite the amount of intelligence and foresight; he's well aware that he can't just kill, say, his favourite cook if he wants food later and dwarven exploitation of the elves and the forests is bad (if only because they're greedier than he). Of course, once he comes to see how greedy and evil the senators can be, he starts to get appreciative of the new 'democracy' in his former kingdom. Paraphrasing his words, they're just as bad and decadent as he was, they just can hide it better.
Reaver in Fable II: he's arguably more evil than the game's main villain, being not just a mass murderer but cold-blooded and sociopathic. The only thing that keeps him from being a far greater threat to the world is his lack of ambition and scope.
Though twenty years later in Sword of Seals, he has mellowed out quite considerably.
Path of Radiance/Radiant Dawn has a few. First is Izuka, the Mad Scientist from Po R who ends up with Daein again in RD, who utilizes deplorable tactics for the cause, though he was serving two other causes at the time, all three of which sought very different ends. Second is Soren, who really seems indifferent to everything other than Ike, and is more suspicious of others' motives than his teammates. Finally Shinon, an unabashed racist who never repents even given the somewhat Anvilicious race-based events in the game.
Morrigan in Dragon Age: Origins is the daughter of the infamous Witch of the Wilds, Flemeth, and while she claims to be an ultra-pragmatic survivalist, most of her actions show her to be rather cruel, disapproving of virtually anything you do that isn't sadistic and cruel. Oh, and you later learn that the only reason she joined you was so she could birth a child with the soul of an Old God. Of course, she arguably does have standards... just not many.
There's also Zevran, an assassin who initially opposes the party, but can eventually be convinced to join you. Even if he does, he never quite drops his "evil assassin" nature. Unless the PC - who can be of either gender - romances him and convinces him to turn against his old assassin's guild in the endgame, in which he becomes a bit Heroic Neutral.
Dragon Age II is set in a Crapsack World with Gray and Grey Morality, but a couple stand out. Isabela, a pirate who stole the qunari's most sacred relic and is willing to let the qunari go to war with Kirkwall to save her own skin (unless you convince her to pull a Changed My Mind, Kid). Anders is a Well-Intentioned Extremist mage possessed by a spirit of Justice whose inability to deal with human emotions is steadily turning it into Vengeance. At the end of the game, he commits a terrorist attack to spark mage revolution - you can kill him, tell him to go or let him rejoin you. Of course, the rest of your teammates have their own flaws (particularly Sebastian, who vows to recruit an army and raze Kirkwall to the ground if you spare Anders after the Chantry attack). This is perhaps the biggest Dysfunction Junction in Bioware history.
Jack and Zaeed, while they don't end up being fully redeemed, can at least be convinced to see things in a Paragon fashion, Jack by helping her deal with her past and convincing her that you're not merely out to just use her and Zaeed by punching him in the face and threatening, at gunpoint, to let him burn in a factory like he would have done to innocent hostages.. Morinth, on the other hand, is a monstrous character who has no intention of ever-changing and enjoys what she does.
Mass Effect 3 has Javik, though he's not so much evil as he is just brutally pragmatic and ruthless in dealing with the Reapers. He also has zero tolerance for synthetic lifeforms and believes that they have no right to exist.
Then there's Aria T'Loak. Sidequests she give you during the main course of the game implying assassination of head of one crime group to promote Aria's marionette or turian general, who stops other group from plundering the weapon deliveries (which can be avoided), or releasing AxCrazy head of the third group from C-Sec (which can be avoided too, by provoking her vice to kill her to take her place). Then she becomes the actual teammate for Omega DLC, where she ruthlessly forces Shepard to kill hundreds of Omega civillians just for her to survive (which she does anyway), and then murders the surrendered Cerberus general, if not stopped.
In a sense the Batarian Hegemony is this to the other Citadel races. They're the only member nation with a garden-variety dictatorship for a government and which still practices slavery. They're considered a rogue state, but not to the extent of the Terminus Systems which are just a loose conglomeration of feuding fiefdoms.
Suikoden V has Nakula, an Ax Crazy killer who makes absolutely no attempt to hide the fact that he wants to murder one of your other teammates.
A little elaboration is needed. He's not "evil by design". Rather, he's just insanely pissed one of your other teammates murdered his father, and though he really wants said teammate to die (who even acknowledges he's right to be so angry), he's willing to be professional enough to put his grudge aside to aid you, even against his own people, mostly because they gave him up for dead.
Green Goblin and Venom eventually join your group in Marvel Ultimate Alliance 2 after you free them from being controlled by the Fold, a hive mind of nanite-possessed people. Judging from their dialogue with other characters, where they're total Jerkasses, they're not too happy about it. The partnership between them and the heroes is a strict Enemy Mine to take down their common foe.
A lot of the hirable mercs in the Jagged Alliance games are either Axe Crazy, massive Jerkasses, or both. They'll ignore orders if they're busy trying to kill a baddy, annoy other team members so much that they quit, or (in some instances) murder teammates that they dislike between missions.
As of the true ending for BlazBlue: Continuum Shift, the main group of heroes have two of these in the cases of Jin and Kokonoe. Though to be fair, they're not so much evil as "total prick" and "amoral Mad Scientist", respectively. However, this might be subverted that Jin is put under tutelage of Jubei, one of the few unflappably good persons in the universe, meaning it's just a matter of time until he stops being a Token Evil Teammate. Kokonoe on the other hand is standing on the edge of the Moral Event Horizon and seems undeterred by that fact, too, so the only thing "good" about her right now is that she fights Terumi.
Speaking of Terumi, he was the Token Evil Teammate of the Six Heroes. He only allied with them out of nececity when he realized that the Monster of Mass Destruction that he had secretly created wasn't controlable, and since it was now indiscriminately destroying the world, as opposed to destroying it the way Terumi wanted it to be destroyed, it simply HAD to be put down. Also, one of the heroes, a witch named Nine, put him under a geas that he WILL have to obey her so he's steered to destroy his creation. When the monster finally had been killed, Nine managed to catch whiff of the fact that it had been Terumi who set it loose in the first place, so he simply HAD to kill her (that and he didn't take being mind-controlled that well)... Guess who of the two people mentioned in the above paragraph Nine was the mother of? I'll give you a hint: It wasn't Jin.
Now that Blaz Blue Chrono Phantasma is announced, it has been revealed that there's ANOTHER Token Evil Teammate amongst the Sector Seven... Azrael. At least Kokonoe can be touted as a Nominal Hero. Azrael is already said to be a villain of the series, though he may be unrelated to whatever the main villains are planning.
Okage has one (kind of) in the form of Stan. Evil King Stan believes himself, clearly, to be evil, and thus goes along with Ari to destroy the other Evil Kings and regain his power to do...evil things, apparently. Ironically, a majority of the Evil Kings Ari defeats ends up joining their group.
In Fist Of The North Star Kens Rage, Jagi becomes this for the Hokuto side in Dream Mode, choosing to take his chances with his brothers after royally pissing off Thouzer. Jagi was one of the biggest monsters in the series, although for this one mode, his brutality has been toned down with some hilarious moments.
This also extends to Raoh of the Hokuto Side, since by default, he's the ruthless Big Bad, and even when he's a Noble Demon, he's still got the evil within him.
In Namco X Capcom, amongst multitudes of good heroes, one of the members you can get is Tekken's Heihachi Mishima, one of the chief antagonists of the series. Though to be fair, he's on the 'Thou' part on the Eviler than Thou deal against Devil Kazuya...
In the original translation of Final Fantasy Tactics, Gustav Margueriff seems to be this for the Death Corps. Aside from his Marquis-kidnapping shenanigans, which damaged the reputation of the Corps (just as the guy who was paying him off to do it intended), his Brave Story biography had it that he was kicked out of a knightly order for his war crimes (i.e. rape and pillaging) before joining up with The Idealist Wiegraf's forces. The new translation, however, completely inverts his background—the rest of the order was full of war criminals and Gustav left in disgust, though this doesn't stop him from making life difficult in the present.
Iori Yagami plays this for his official teams in KOF 2001 and XI.
In Magical Girl Lyrical Nanoha As Portable: The Gears of Destiny, everyone who had joined forces to fight the Unbreakable Darkness is doing it for good reasons, may it be to stop the Eldritch Abomination from destroying everything, to fix the mistake they did for unsealing her in the first place, or because they're completely loyal to both their master and their newfound friends and would like to have fun times after beating the threat. Well, everyone that is, except for Lord Dearche, the Evil Overlord-like Humanoid Abomination who's only doing it because she plans to take the unlimited power of the Unbreakable Darkness and use it to kill all her non-Material allies so that no one would stand in her way as she begins a reign of darkness! She was slightly annoyed when her fellow Materials protested her plans since that would mean that she'd kill their new friends too. Damn minions straying from their original mission of bringing chaos to everything and becoming all nice behind her back...
Margrid The Sly joins your party in Guild Wars. She's a member of the Corsairs, a ragtag group of bandits you've been fighting since level 1. It just so happens she can provide you with a quick escape from one mission, and she has no qualms with helping you as long as you can pay up. She ends up joining you permanently, though (she claims) it's more for money and treasure than the chance to be a hero.
Also, Magik in the same game, if you get her, in a weird way. When she join you, she could count as a normal heroine. However, as of Avengers Vs X Men, Magik turned out to be Evil All Along, so she could've counted. However, for the game, her 'evilness' have been toned down a bit, subverting this trope.
Arudin from Dungeon Crawl Inc. is this, though he insists he's merely "colorfully pragmatic." His most vile deeds occured years before he joined the comic's Five-Man Band, when he was an agent of the elven terrorist organization Eldreth Veluuthra. He did a Heel Face Turn and nowadays he's mainly a snarkyJerkass.
Honestly, Thief and Red Mage are bad enough that classifying Fighter as the Token Good Teammate would probably be more accurate.
While the Light Warriors as a whole are inept, stupid, violent, destructive and selfish, Black Mage stands out because he wants to destroy the world and everyone in it for no real reason. It's suggested that its his own presence that causes the rest of the Light Warriors to be what they are.
Richard in Looking for Group (pictured above) is this. On page two, we see him use an innocent bystander as a human shield. He then gleefully considers the prospect of killing the man's wife and young son, to "complete the set." The rest of the party is grey or good (Cale).
Oddly enough, despite Richard killing Cale the first time they met (he got better), and Richard's constant Crossing the Line Twice, by now Cale misses him so much when he is not around that he set his own hands on fire reminiscing. When Richard returned, there were hugs.
Also interesting in that it's played completely straight, bordering on deconstruction. The implications of a mostly good party putting up with the sometimes utterly despicable actions of a teammate who shows them little loyalty are thoroughly explored.
And then Reconstructed with Roy giving a lecture not only on how Belkar can be controlled, but why it would be a bigger risk not to try.
Nevertheless, Belkar still is very much "south of Neutral", in Haley's words - which is sometimes not a bug, but a feature.
Bun-Bun from Sluggy Freelance is a sociopath through and through, but the other characters keep him around partly out of sympathy, partly because his raw toughness comes in handy, and partly because he'd kick their asses for trying to get rid of him. Over the years, the cast has gotten quite good at "Bun-Bun-fu", arranging situations so that it's in Bun-Bun's best interest to help them.
Riff: I'm going to sweeten the deal! What do you think of this, Bun-Bun? Bun-Bun:(unimpressed) It's an empty wallet. Riff:(points to bad guy) And I bet his is full of cash and credit cards. And you've got to bodily throw one of us out. Bun-Bun: Fair enough! Time to mug and take out the trash!
Even more blatant a recent arc, where Bun-Bun goes up against Oasis under the guise of doing it only for a huge pile of cash, only when he finally encounters her he has this exchange:
Bun-Bun: I'll get right to the point, Red. You simply have to stop messing with and killing the dweebs in my life. They suck, I know, but they're my dweebs. You're making me mad. But you know what's going to make you madder than me? Bun-Bun: I know where Torg is and I'm not telling. So what are you going to do about it, Crazy-Pants?
Each time he got drunk he would tell the rest of the cast that he actually appreciates them...
Girl Genius: Baron Wulfenbach seems to keep Bangladesh Dupree on the payroll because it's better to have her using her destructiveness at his call rather than simply running loose. Of course, that leash isn't very tight.
Luke from Freakangels decided one day human morals really weren't his thing and has been going downhill ever since.
Bezzler the thief in Nodwick essentially stole everything he could get his hands on and nearly bankrupted his party several times before Yeager slipped him a "Magic Helm of C'ntrol-Ault-Delete" (and again until Nodwick dealt with him after this wore off). Although in day-to-day life Yeager seems to play this role despite not being officially evil (often helped by Artax), largely due to his tendency to treat henchmen as Acceptable Targets.
YMMV Bezzler fits right in as far as his lawful good replacement Nodwick is concerned too well he's a henchman abusing thief like Yeegar and Artax. Arguable he is just skilled.
Ken in No Need for Bushido is a Sociopathic Herojerkass who is something like a combination of Mugen and Prince Zuko but without either of their noble qualities. He's shown brutally mugging innocent people several times as a way to keep the group in-funds, and his good teammates are willing to tolerate this.
Bob in Bob and George is evil, but still hangs out with his brother George and the rest of the main cast. He even saves George from trouble a few times. However, none of this stops him from occasionally trying to take over the world or kill everyone.
At first, the Trolls in Homestuck seem to have one in Terezi "gallowsCalibrator" Pyrope. In Act Five, however, we meet the other Trolls; compared to Vriska "arachnidsGrip" Serket, Terezi is a saint. The worst thing Terezi has done was leading the protagonist to get himself killed by taking on enemies stronger than he could manage in an alternate timeline, and she did this knowing he would be back. Vriska, on the other hand, forced one of her teammates to jump off a cliff and paralyze himself, then mind controlled another teammate into murdering his lover, and forced Terezi into staring into the sun until she went blind. Terezi haskilled trolls during her time as Vriska's partner in FLARP, but according to her, she only killed the "bad" ones, while Vriska just killed everyone.
To the surprise of no one, among the less violent pre-Scratch trolls, the Token Evil Teammate was Meenah, whose post-Scratch counterpart is The Condesce.
No longer true as of 9/24/12 with the reveal of Kurloz Makara
And Damara Megido is almost as bad.
Heck, by now both Terezi and Meenah, who seemed the Token Evil Teammate of their respective team, are respectively one of the most moral trolls in all sessions and an Anti-Hero. Meenah is a major jerk sure, but she has good intentions and a capacity for loyalty. Damara and Kurloz, on the other hand....
When he's sober. When he's drunk, he turns into a nice guy.
Galatea in The Inexplicable Adventures Of Bob seems to be very slowly growing a set of morals, thanks to her family's influence. She at least acknowledges that hurting innocent people is bad, but she still believes conquering a planet and setting yourself up as dictator is okay as long as no one gets (immediately) hurt. Bob pointed out that people would inevitably get hurt in the long run, and that gave her pause. So, she's gettin' there...
Trudy of General Protection Fault, who was quite over-the-top evil in the first few years, literally as well as figuratively kicking dogs. As Cerebus Syndrome set in, she became a slightly toned down villain who was manipulating the rest of the cast to take over the world. After being defeated and forced on the run, her ex-boyfriend Trent took over her position, proving to be the most selfish and amoral of the GPF crew during his time there. The fact that both of them were in the same position gets lampshaded.
Nick: Do they make marketing people in a less maniacal flavor?
The trope isn't played completely straight with Trent, however. Dwayne shows more patience with his antics than he really deserves, though it's fair to say his feud with Fred isn't entirely one-sided, but Trent [[ http://www.gpf-comics.com/archive/2005/08/17 does eventually push the Team Dad too far.]]
In Gods Playing Poker, Cthulhu himself is generally on the side of hurting people and eating souls, although the actual group doesn't do much literal heroing, being mostly composed of holy figures of various faiths.
In Darths & Droids, Pete doesn't exactly play his character evil, but as more of an insane and completely ammoral psychopath. Though he doesn't seem to be aware that there is anything unusual about it. And it's R2-D2 of all people.
DM was also going to enter Kurahadol into the team, but instead illustrated some of the problems inherit to this; he was so excessively rude to his would-be party members that by the end of their first meeting, Luke was asking if they could just kill him off so she'd have to roll up a new character.
Many of the characters from Red vs. Blue can occupy this role depending on their current motivation. Sometimes Church; most often, Tex. After season 2, when the teams are frequently allied against a greater threat, Sarge views the Blues as a collective Evil Teammate.
While the whole main cast of Flander's Company is made of Villain Protagonists, it's revealed in season 2 that their Token Good Teammate possesses a Super-Powered Evil Side who is even eviler and more psychopath than any of them. Trueman successfully awakes him and convinces him to help them with the current crisis in exchange for the guarrantie he will be left in control every week from thursday to wednesday. Eventually deconstructed in season 4, where, after the death of his good side, he goes rogue and become the True Final Boss in the finale.
Kirby from Sonic For Hire, who is a whole lot eviler in this series than he normally is. He doesn't mind swallowing or hitting innocent creatures or servants with umbrellas.
Bender: From now on I promise I'll never be too good or too evil again. I'll just be me. Leela: Do you think you could be a little less evil than that? Bender: I dunno. Do you think you could survive a 700 foot fall? Fry: Good old Bender.
Given his near-total lack of regard for human life and number of Doomsday devices, one could also make a case for Farnsworth being this.
It's more like Billy is the Token Good Teammate as the other two in the Power Trio are a morally bankrupt and apathetic being, and the Grim Reaper. Of course, Billy's behavior often bordered on psychopathic and insanely selfish, it's really just that Mandy is more generally malevolent.
And the only reason Billy could be considered good is because Good Is Dumb. Some episodes have Grim as the Token Good Teammate, depending how far Billy has gone this time (with Mandy keeping them in line for her own sanity and evil plans). You know how weird things are when the Grim Reaper is the Only Sane Man.
Joseph Stalin in the "Freedom League" sketch on Histeria!
Dinobot serves this role in Beast Warsfor about the first two seasons. Shortly after his death, Blackarachnia takes over.
Buford from Phineas And Ferb isn't actually evil, but he is rude, intimidating, and a self-professed bully.
Prince Phobos, the former season's Big Bad, takes this role briefly during the second season of W.I.T.C.H., because he's the only person who can take the new Big Bad's Amplifier Artifact away from her without it instantly teleporting back. Phobos spends a handful of episodes grudgingly helping the heroes (while acting like a titanic Jerk Ass to them all the while) and then he finally gets what he wants- said Amplifier Artifact for himself. He promptly betrays everybody and resumes the throne of Big Bad.
Word Of God is that if the planned Gargoyles spinoff Gargoyles 2198 ever gets made, Demona, Big Bad of the existing Gargoyles series, will take this role. It's not that she's gotten over her Fantastic Racism towards humans, but more that she's decided she likes the Scary Dogmatic Aliens who've taken over Earth even less — for now. Whether she'll eventually morph into The Atoner or take back the Big Bad role herself is left deliberately unanswered.
This is Gargoyles. She'll probably do both, simultaneously.
Well, he considers himself a Magnificent Bastard, but really doesn't live up to it. Heaven help Meatwad if Shake ever realizes what his super power is though (everything he throws explodes when it hits the ground, but he never notices).
