Reliable Traitor

""Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.""

- Jack Sparrow

A minion of the Big Bad, down from Les Collaborateurs up to and including The Dragon, who is motivated by pure self-interest. They talk back, dislike their associations, and overall make clear they don't like the antagonist. The Big Bad is nonetheless assured this will be their best minion (until they desert) because they are not concerned with sucking up, just getting results and getting out of whatever debt or obligation makes them work with villains in the first place.

If done well, the Reliable Traitor comes off as not always good, just not evil, making them a good candidate for the Enigmatic Minion, as well. Usually will (un)wittingly help heroes Fighting for Survival.

Compare The Starscream, Lovable Traitor, Self-Proclaimed Liar. Often prone to Chronic Backstabbing Disorder.

Anime and Manga

 * Happened more than once in Sailor Moon. This was lampshaded in the Live Action Adaptation, where Queen Beryl explains to an annoyed minion that she's aware her generals don't always particularly like her, so she allows the in-fighting between them as a distraction that pushes them to be more creative against each other.
 * The Black Beauty Sisters in Mermaid Melody Pichi Pichi Pitch.
 * Subverted in Soukou no Strain: the traitor openly plots against Ralph for ages, but
 * Motoharu in A Certain Magical Index is working for several organizations as a spy... and every one of them knows it. However, since he's pretty good at what he does, they tend to overlook it.
 * Ichimaru Gin of Bleach. He tells you straight to his face that he's a snake.
 * Aquarius from Fairy Tail will attack everyone indiscriminately, friend and foe alike. But when all's said and done, she usually ends up being helpful overall.

Comic Books

 * The X-Men franchise has Sabretooth. Whether it's Weapon X, the Brotherhood, Apocalypse, or even the X-Men themselves, no one who employs him ever really trusts him. With good reason, too, as he's one of the Ax-Craziest of Marvel's creations.
 * Everyone on Dark Avengers who wasn't Ares or The Sentry. Especially Daken. At least until Siege, when both of them ended up betraying him.
 * V for Vendetta has Inspector Finch. He criticizes Susan's dictatorial regime to his face. As Sutler's puts it, the fact that Finch is still alive proves how appreciated his work is.
 * Mycroft Holmes invokes this with regards to Campion Bond in The League of Extraordinary Gentlemen. When Mina asks if Bond will be punished for his deeds, Holmes replies in the negative, saying, "It is often useful to have employees whom you know to be treacherous."
 * In Sonic the Hedgehog, Eggman has stated that he knows full well that Snivley, Lien-Da, and several others are planning to overthrow him, but because of that they will work the hardest for him, because they want to inherit a strong empire. He actually goes through the trouble of saving Lien-Da simply because he was impressed by her attempt at his position.
 * He actually recruits by asking people to try to overthrow him, and calls it "The Game"
 * It was recently revealed that Loki allowed himself to die at the end of "Siege" and be reborn as a child because he realized he had become a Reliable Traitor. As a god of trickery and chaos, he could not bear to be predictable.
 * The One Sith in Star Wars Legacy try very hard to avoid being Reliable Traitors. The self-serving nature of the Dark Side makes it very difficult.

Film
""You can't trust Melanie, but you can trust Melanie to be Melanie.""
 * Any Sith in Star Wars, given that Chronic Backstabbing Disorder is one of the side-effects of The Dark Side. The Star Wars Expanded Universe is filled with examples of characters using this against the Sith or a previously powerful Sith Empire eating itself because all of its members were... less than trustworthy. The Rule of Two - which is how the Sith operate by the time of the films - was intended to control this treachery and actually turn it into a strength, though given how both Palpatine and Vader fully expected the other to use Luke against them it wasn't a perfect arrangement.
 * Jack Sparrow of Pirates of the Caribbean has betrayed every other character in the series at least once, but he's so motivated by self-interest (usually) that he can still find allies.
 * In Superman II,
 * Melanie in Jackie Brown.

Literature
"Ye mind I warned you I might play false. Well, this is it, ould joy, and if I said it grieved me I'd be a liar, which I am, but that's naught to the matter."
 * Achilles to Agammemnon in The Iliad.
 * The heroic version is exemplified by Major Elim Rawne of Gaunt's Ghosts. Early in the series he doesn't disguise the fact that he hates Colonel-Commissar Ibram Gaunt and, when the time is right, fully intends to kill him. He even tells people this. Gaunt not only knows, he gave him the knife (to replace one Rawne lost) which everyone expects Rawne to use in the attempt. He eventually mellows out about the whole "Killing my commanding officer" thing.
 * David Eddings' Elenium and Tamuli series, Krager is regularly kept around by both sides, the villains because he's a competent minion, the heroes because he coughs up information worth a lot more than his life fairly willingly. Ironically, at the end of the Tamuli series, he's dying of self-inflicted illness due to his heavy alcoholism.
 * In A Song of Ice and Fire Littlefinger has this trope wrapped around his, er... little finger. Not only is he purely out for himself, but he manages to convince other characters that this makes him reliable From a Certain Point of View... which never turns out well for them.
 * Lady Invidia Aquitaine from the Codex Alera has betrayed almost every character in the series at least once, to the point of being The Dragon to two Big Bads (both the initial apparent one and the ultimate real deal) while having several Enemy Mine moments with the heroes..
 * On the other end of the spectrum, we have Fidelias, who fits the description above almost perfectly. He turns on Gaius Sextus because he feels his politicking is destroying the country, and becomes the Aquitaines' chief spy despite not liking them much because he thinks Attis would be the best leader.
 * Colonel Thomas Blood in The Pyrates. He even warns the hero of this, when he first signs on. Later, when Blood runs out on the hero, he leaves a note which actually says:

"Caine: Whose side are you on, Diana? Diana: I'm on my side."
 * Diana from Gone (novel) is very open about the fact that she can't be trusted.

Live Action TV
"Sterling: Your entire plan relied on me being an arrogant, self-serving bastard. Nate: Oh, yeah. That's a stretch."
 * All over the place in Hustle. A lot of the time, their marks are so reliably likely to turn on the gang that Plan A relies on it entirely. In some cases, it even goes so far as to mess up a perfectly good plan when the don't try to betray the gang...
 * Subverted in Firefly with Jayne. Everyone fully expects him to turn on them if given enough (monetary) incentive and are prepared for it, however not only is Jayne far more loyal than even he realises but the time he does betray them isn't suspected at all, and Mal is far more furious than he would be if he expected it.
 * Supernatural has one of the Winchesters point out that the Trickster/ is playing a trick on them. His response? "Hello, Trickster?"
 * The demon Crowley starts out like this, before heading sharply into Magnificent Bastard territory.
 * The Leverage team can only beat Sterling when Sterling wins too.

"Angel: Loyalty really isn't high on your list. Harmony: Oh, is that right? I'll have you know I am damn loyal, dumbass. Angel: You betrayed me. You are betraying me now, even as we are talking!"
 * On Angel Harmony can be relied on to apologetically backstab her friends whenever a better option presents itself, though she doesn't like to admit it. Her backstabbing them actually factors into their plan in the finale.


 * A few castaways throughout the seasons of Survivor have fit the bill, but the most straightforward example is Cook Island's Jonathan Penner. After mutinying from the Aitu Tribe when the opportunity presented itself, he later turned on his new alliance to help the tribe he left behind conquer a numbers disadvantage during the Tribal Merge. The reason? Yul Kwon, (Aitu's de facto leader) threatened Jonathan with his hidden immunity idol, knowing that Jonathans' interest in self-preservation was greater than his loyalty to the Raro Tribe.

Tabletop Games

 * The Chaos God Tzeentch in Warhammer Fantasy Battle and Warhammer 40,000 is the Anthropomorphic Personification of this trope. It and its followers are mysterious and unpredictable, but the one guaranteed thing about them is that they will screw anyone and everyone over if it serves (or even if it runs contrary to) some nebulous "master plan".
 * Kharn the Betrayer. Almost everyone knows that he'll kill anything near him just for being near him, enemy or not. It's a testament to Kharn's bloodlust (and his compatriots' insanity/stupidity) that this doesn't usually save them.
 * In Exalted, this is the very core of Ebon Dragon's being: you can count on him betraying you at some point. In fact, he can count in him betraying himself at some point.

Toys

 * "Darkness" (it's a Code Name) from Bionicle hangs over the Shadowed One's shoulder, waiting for him to show weakness so he can kill him and assume leadership of the Dark Hunters... The Shadowed One is well aware of this and actually encourages it; the idea being that this way the Shadowed One will be ever vigilant and never go soft.

Video Games

 * In the Barbarossa campaign of Age of Empires II, Henry the Lion betrays Barbarossa, but is still forgiven, considered a valuable ally. Then he betrays you again, and is banished.
 * Etna from Disgaea makes it rather clear to Laharl that she'll kill him where he stands if he doesn't prove himself worthy. Laharl just sees this as even more of a reason to promote her to second-in-command.
 * Archer in Fate/stay night. Lancer and Assassin also have shades of this trope, being motivated by being Blood Knights while being stuck with Masters who deny them battles, but neither of their masters appreciate them either.
 * In Dawn of War, Lord Bale expresses concern over joining forces with the Orks against the Blood Ravens due to their unpredictability, to which the Sorcerer Sindri replies "Orks are not unpredictable. On the contrary, you can rely upon them to turn against you." It doesn't matter either way, since the Alpha Legion's scheme was made to work no matter which side won and started fighting them directly.
 * Winter Assault features two very brief alliances, which are brief because each side expects the other to betray them, and each side doesn't disappoint. However the fact that each of them betrayed the other side because they expected the other side to betray them might put this into Self-Fulfilling Prophecy territory.
 * In Dawn of War II: Retribution, Abaddon fully expects Eliphas to betray him at the first opportunity, but isn't concerned as for the moment Eliphas is completely under his power and must follow his commands. This incredibly short-sighted behavior might contribute to Abaddon also being known as Failbaddon.
 * Warcraft has plenty of these. First case was Evil Sorcerer Gul'dan, who Orc Warchief Orgim Doomhammer kept around because he knew Gul'dan would be useful to the Horde, even though he didn't trust the warlock. Statements about Gul-dan say that he preferred having himself surrounded by untrustworthy, ambitious individuals like himself because he knew how they thought, and actually didn't like having individuals motivated by loyalty around him because he had no clue how they thought. Additionally, Ner'zhul, the Lich King, works for Kil'Jaeden despite quite clearly having ulterior motives—since Kil'Jaeden never trusted Ner'zhul, he had his Elite Mooks, the Dreadlords, watch the Lich King.
 * Some early editions of Romance of the Three Kingdoms on the SNES had an oddly literal example in Lu Bu. While undeniably the deadliest general in the game whose WAR rating was unparalleled, he was almost impossible to use in that function because he could be counted on to turn on whoever he served if you provided him with a modest bribe. Even measures to ensure high loyalty wouldn't come to much—a little more gold and your best warrior was off to join the opposition. On the other hand, coming across Lu Bu was not as threatening as it might be in other games, because any half-decent strategist could bribe the clueless brute in return, bringing him over to your side for the turn. You could even mess with history by doing this to Dong Zhuo during the campaign to overcome him. It eventually leads to the bizarre situation where you have the greatest warrior in the land, and you're keeping him holed up in some corner of the kingdom training troops for the rest of your officers. While the early games didn't offer the greatest amount of characterization, this is Lu Bu we're talking about. I think it's been demonstrated that he's not exactly the most loyal of people.
 * In Arc the Lad: Twilight of the Spirits, Darc (a deimos who believes firmly in Asskicking Equals Authority) spurns letting any deimos who is slavishly loyal to him serve him, since he sees it as a sign that they're weak and would turn on him as soon as a stronger overlord turned up. In contrast, he happily welcomes Delma back into his service after she stabs him in the back, leaves him for dead and tries to steal control of his clan from him, seeing it as an acceptable display of strength on her part.
 * Knights of the Old Republic, being part of Star Wars, not only inevitably features this amongst the Sith but even allows the player to implement it in the Sith Academy, playing Reliable Traitors against themselves as a distraction for their own treachery.
 * In Dragon Age: Origins, the Tevinter magister Caladrius is openly contemptuous of his patron,, and immediately offers to betray him to the protagonist if he is allowed to live and still make a profit on his Evil Plan.

Web Comics

 * In the Sluggy Freelance storyline "Oceans Unmoving," Bun-Bun purposely makes the most untrustworthy member of his pirate crew the first mate, because he "feels safer knowing where the next mutiny will come from."
 * In Girl Genius, the entire Sturmvoraus clan seems to breed nothing but these.

Web Original

 * In Whateley Universe, half of the campus security is made of these. EVERYONE is spying on EVERYONE for SOMEBODY, but it all cancels out, so everyone ends up working as reliable cops. Some are more snarky and bickering then others, though.
 * There was that one guy with Humans First, who tried to kill Tennyo...

Western Animation

 * In Transformers: Beast Wars, Megatron thinks of Tarantulas this way, who presents a facade of loyalty and fools Megatron about as often as Megatron sees through it.
 * From what impressions we are generally given of Predacon 'culture', betrayal and treachery are expected, as they ensure that only the strongest and most capable remain in command. "I can tolerate your treachery, lieutenant, but NOT YOUR INCOMPETENCE! Treachery requires no mistakes."
 * The other spider, Blackarachnia, fits into this trope much more neatly, often voicing her dissatisfactions. Notably, her ambitious personality was purposely designed by Tarantulas, whose Mad Scientist expertise first converted her from a Maximal. Turns out she was pretty much like that anyway even without the cerebro shell, which makes you wonder what the point was.
 * Yet another example is Rampage, who openly has no loyalty to Megatron, but is kept in line by routine reminders of the Restraining Bolt and the upside of opportunities to terrorize and demolish.
 * On the subject of Transformers, this was the exact reason why the Trope Namer for The Starscream was not destroyed. He was a capable scientist and the leader of the best fighters in Megatron's army and therefore inexpendable. This has been remedied in Transformers Animated, where he does not have such luck and
 * Ironically, this occurred to the original Starscream as well, who came back as a ghost.
 * In Transformers Prime, Megatron admitted he kept Starscream around because his repeated failures were entertaining.
 * Granted, Prime also demonstrates that Megs is probably well aware his entire crew except for Soundwave would off him if they thought they could get away with it. Starscream's just the only traitor with the guts to be proactive about it, which kept Megatron entertained until Starscream started becoming too predictable to be of any use to him.
 * Wuya from Xiaolin Showdown, after falling victim to the Sorting Algorithm of Evil and becoming a minion of Chase Young. She's so reliably untrustworthy it makes her MORE predictable, and he incorporates her inevitable betrayal into his plans.
 * Iago in Disney's The Return of Jafar abandons Jafar and moves in with Aladdin and Jasmine. Then when Jafar returns, he switches sides again. Guilt, however, prompts him to make a third turn towards the heroes, this time acting against his own best interests.
 * Jafar actually lampshades Iago being a reliable traitor as a compliment since it fits into Jafar's plan of revenge against Aladdin, though Jafar's ownership of the Villain Ball and Contractual Genre Blindness does him in when he forgets/ignores the possibility of Iago taking one last turn on the ol' Heel/Face wheel.
 * And at the end of the third movie, he takes a third option and flies off with Aladdin's father, the King of Thieves. "You're a nice guy, Kazim. But not too nice."
 * Capt. Barca in Exo Squad.
 * The Secret Saturdays had Doyle's girlfriend betray him for Van Rook in her second major appearance. What makes her this trope is that she

Real Life

 * Talleyrand. Quoting his wikipedia page: "Some regard him as one of the most versatile, skilled and influential diplomats in European history, and some believe that he was a traitor, betraying in turn the Ancien Régime, the French Revolution, Napoleon, and the Restoration."
