"We will not allow her to fall from grace. Instead,
we will be the sinners."
A character defined both by their obsessive loyalty towards a target character and by their vastly divergent (and comparatively "cynical"
) moral code.
The Poisonous Friend is usually attached to a pacifist protagonist
or an idealistic villain
. They tend to consider their "master" a person to be worshipped or protected at all costs — even ones that the master would not knowingly permit
For example, if the master is a Fettered
pacifist completely against killing his enemies
, the Poisonous Friend
might pay lip-service to this trait while the master is nearby... and then turn around and butcher the enemy behind the master's back. If caught, they'll claim they just "did what had to be done"
. Few masters catch on.
Sometimes the master's influence gets through to the Poisonous Friend
, with results such as Badass Decay
. In other cases, the Poisonous Friend
continues to pose a danger both to the master's other friends (through jealousy)
and to the enemy. The Love Interest
is in particular danger
of the Poisonous Friend if they suspect them of making the master "vulnerable".
Though sometimes introduced as anti-heroes or turncoats from the other side, they cease to be those things because they place their fundamental loyalty upon the shoulders of their "master". Basically they become a good guy's secretly-evil minion, or a bad guy's much-badder sidekick
This character is often used when writers don't want to stain the "innocent" master's hands but still need a way to deal with those pesky defeated enemies. Even friends who have been explicitly told to behave or otherwise decided to hold back can still function in this regard if they have done something bad or really bad
enough to intimidate the villains. If a particularly noble
hero cannot wrong anyone
, but has a particularly cruel
poisonous friend, the villain may hesitate to take advantage of that hero's idealism and kill him out of fear of what his buddy's response could be
The name of this trope comes from a song by the band Seabound
If their behaviour actually starts to rub off on the hero, it's Toxic Friend Influence
. If the hero retains their own morals but still knowingly tolerates what this character gets up to, see Psycho Sidekick
Contrast: Psycho Supporter
, The Only One Allowed to Defeat You
, Loony Fan
, Shoot the Dog
. Compare Big Bad Friend
. Not to be confused with Poisonous Person
, in which someone is literally
poisonous, though they can be combined. Also not to be confused with False Friend
, in which one deceives another as being their friend, only to have an ulterior motive to do so. A Mysterious Backer
might turn out to be one of these.

Anime and Manga
- Subverted in The Twelve Kingdoms: In the last arc, Kouya initially appears to be a Poisonous Friend to his leader, Atsuyu; he murders dissidents regularly and claims to have "exiled" them when Atsuyu, who is presented in a positively saintly light, asks. However, Atsuyu is revealed to be a Manipulative Bastard who abuses Kouya's extreme loyalty to get away with atrocities while keeping his own hands clean.
- Death Note: Misa is unwaveringly faithful and supportive of Light Yagami — and also much cruder and more indiscriminate in her use of the Death Note, which Light considers an insult to his goal of punishing only criminals.
- Mikami's even worse, killing exactly a page a day, but killing reformed criminals and those that Light thought were redeemable or innocent.
- Code Geass has a pseudo-sibling version of the trope in Rolo, who has an obsessive devotion to his "brother" Lelouch... so much that he wants to prevent Lelouch from reuniting with his real sibling, and murders Lelouch's possible love interest when Rolo decides she might get in the way of this goal.
- Lelouch himself is this to his much loved sister nunnally, willing to kill countless people for her to live in a better world.
- Diethard is another extremist among Lelouch's company. When Suzaku is made Euphemia's Knight, Diethard calls for him to be assassinated. Lelouch suspects that he talked Kallen into trying to kill Suzaku at a party for him at the Ashford Academy, and warns him not to interfere with the military.
- V. V. is a Poisonous Brother to Charles. He is so devoted to their goal of "a world without lies", he murders Charles' most beloved consort, Marianne (which has the side effect of setting the events of the series in motion), among other things done behind his brother's back. None of this is lost on Charles, who, now fed up with V. V.'s lies, takes his code and leaves him to die.
- Fiore from the Sailor Moon R movie is a textbook example; obsessed with his friendship with Mamoru to the point that he'll destroy Earth for his sake, even though that's not at all what Mamoru wants.
- Yubel from Yu-Gi-Oh! GX, one of Judai's Duel Monsters, who he apparently sent into outer space when she started killing anyone who defeated or upset him. She now holds a homicidal grudge against Johan because of his friendship with Judai. she gets better after she and Juudai fuse their souls
- The Chessmaster Kyoya Ohtori (and, to a degree, all other male members of the Ouran High School Host Club) is utterly devoted to the idealistic and naive club founder Tamaki Suou, and is not above using dirty tricks and threats to cover up for his blunders from the shadows, which Tamaki generally fails to notice. This is most evident in episode 14 ("Covering the Famous Host Club").
- An especially absurd example would be Legato from Trigun, who decides to torture and kill Vash while Knives, the Big Bad, is recovering from his last encounter with Vash, knowing that Knives will kill him when he wakes up.
- In the manga, he does. In the anime, Vash does it first because Legato knows that killing someone will cause Vash greater anguish than anything he could do. His goal and Knives was "eternal suffering to Vash the Stampede." Legato accomplished this by forcing Vash into a Sadistic Choice, where he either had to kill Legato himself, or be indirectly responsible for Legato killing Vash's friends.
- Also Wolfwood in the anime, most notably when he shoots Zazie the Beast, who looked like he might have been calming down. Vash's idealism has infected him so badly by this point that he ends up feeling horribly guilty over everyone elses' reactions and does a Heel Face Mole, which gets him killed.
- Manga Wolfwood too, kinda. Their philosophical division gets even more development here, and Vash is a darker character though he doesn't kill anyone, but despite Wolfwood's huge conflicts over what's "right" (which ranges from putting a bullet in the back of Vash's head for the good of humanity to actually considering Vash's position) he's mostly of the opinion that you have to make sacrifices if you're going to save anyone. Hanging around with him is a catastrophe waiting to happen for Vash, although the catastrophe turns out to be his absurdly drawn-out death. Vash doesn't help. And he survives and makes spaghetti for the guy who did it. This series is whacked.
- Manga Wolfwood shoots Rai-Dei the Blade in a situation analogous to the Zazie one mentioned above. (Anime Wolfwood shoots Rai-Dei offhandedly in the ruins of August with no witnesses, probably on Legato's orders, and shooting manga Zazie is kind of...irrelevant, since the collective can always find a new host.) He and Vash have a major blow-out about it, but after Wolfwood manages to top the drama-meter by holding Vash's gun to his own forehead and demanding that he pull the trigger and walk forward, able to kill his own enemies and survive, because dying would be worth that, they keep traveling together.
- It's not like Vash didn't have some idea what Wolfwood was before, but the protect-shooting can't be ignored like stuff he hasn't actually seen, so it's a crisis point in both media. Manga Wolfwood is much stronger in his defense of his position because the anime adaption was Lighter and Fluffier even once it got serious, and Vash's philosophy got considerably more positive reinforcement, despite keeping him as Iron Woobie.
- Wolfwood's also defining his place as Poisonous Friend in the gun moment, because Vash is condemning him for killing Rai-Dei, so it's saying both 'get rid of me, then, if you don't want what I'm willing to do for you' and 'without me, you'll have to do your own killing, do you really think you can handle that?'
- The fact that Wolfwood is also, simultaneously, The Mole, The Lancer, and the best friend Vash has ever had seriously complicates the issue.
- Yuno from Mirai Nikki is Yukiteru's creepy stalker-for-a-girlfriend. She'll gladly risk her own life to protect Yuki, and she won't think twice about slaughtering anyone who dares to harm him. She's also extremely jealous, and Yuki finds himself struggling to convince her not to kill his friends.
- Which she eventually succeeds in doing once she decides they don't deserve to be close to Yuki. Great.
- Johan of Monster served as Anna Liebert's Poisonous Brother, murdering anyone their pursuers might have possibly used to pinpoint their location, before she finally caught on and shot him in the head. He got better.
- He also helps Tenma's promotional woes. By killing off all his superiors that were keeping him down. And depending on your interpretation, the entire plot was a gigantic Gambit Roulette by Johan, intended to give Tenma some Character Development and allow him to see clearly how the world really works.
- Even if that wasn't his central goal, he certainly wanted to do that.
- Alucard of the Hellsing Organization clearly qualifies as Sir Integra's anti-conscience by the way he is able to stir Sir Integra into giving him the most ruthless orders so he can indulge his bloodlust as well as succeed in whatever mission he is sent to.
- It's semi-subverted as he implies that she enjoys it, though. Which she does not deny, only saying that it's 'none of your business'.
- It's debatable as to weather or not she enjoys it, as her telling him to shut up about it may be because she wants to cleanse that from her mind.
- Also, if you insult, harm, or threaten his master, you'd better have someone to save you, otherwise you ''will'' regret it.
- Shizuru of Mai Hime could be seen as being one of these to Natsuki; the latter seems pretty horrified when she sees that Shizuru has destroyed First District Headquarters, and her defeating Yukino and Nao and by proxy killing their loved ones- Haruka, and Nao's mother in the name of 'protecting her'.
- Maki from Seto no Hanayome.
- Paul von Oberstein plays this to Reinhard in Legend of Galactic Heroes, purposefully delaying the information that a faction opposing Reinhard was carpet bombing a planet with nukes and later intentionally or unintentionally causing the death of Reinhard's moral compass Kircheis.
- Walter von Schenkopp occasionally plays this role for Yang Wenli, often suggesting that Yang should consider seizing power for himself, forming his own nation, or killing Reinhard after being ordered to surrender just has he has the latter dead in his sights. This is mostly because Schenkopp honestly feels Yang would do better than the pack of Ungrateful Bastards they've been working for who have alternately ignored intelligence or advice from people smarter than them, and (consequently found themselves staring down the barrels of Imperial particle-beam cannons) or screwed Yang over and/or the Alliance over even after Yang just got through saving their asses. One of the prime differences between Reinhard and Yang is that Reinhard listens to Oberstein, while Yang usually rejects Schenkopp's suggestions due to his moral code and general lack of ambition.
- Black Cat: Creed Diskenth takes this to creepy extremes. He has such a constant hard-on for Train that at one point he ruthlessly butchers three intelligence officers for referring to Train as 'that guy'. The kicker is that he does this just after Train, once a heartless assassin, reforms and abandons the life of a killer, deciding to never take another life. Train pays little attention to the fact that Creed goes on a killing spree anytime Train's honour is insulted. (Train's refusal to kill is exclusively in the anime, not the manga, nor does Creed perform acts of killing based on percieved slights to Train in the manga)
- Gilbert from Pandora Hearts is utterly dedicated to his master Oz and will do anything to protect him. Although he hasn't yet killed anyone (onscreen, anyway) for Oz's safety and well-being, he's tried, without any hesitation - despite being the gentlest, sweetest, most pathetic character of the series. However, his backstory flashbacks show that he cold-bloodedly allowed himself to be adopted by an 'enemy house' to become nobility and to steal their secret family weapon (the Chain called Raven), and then became an assassin, all in order to gain the power to save Oz. It gets very, very worrying when poor Gilbert starts experiencing a nearly overwhelming compulsion to kill Alice, despite the fact that Oz adores her.
- Oz himself has had a scary unnatural breakdown in which he wanted to do this for Alice, to stop her from suffering by killing her.
- Hunter ◊ Hunter: Pouf has recently become this to the Big Bad Chimera Ant King Meryem. After Netero's suicide attack nearly killed Meryem and left him an amnesiac, Meryem forgot his Morality Pet Komugi along with his near Heel-Face Turn. A Heel-Face Turn that Pouf disliked. Pouf is determined to kill Komugi to keep said Heel-Face Turn from happening again.
- His Heel-Face Turn in no way involved making nice with the heroes. It probably didn't even involve not conquering the world. It just involved attempting to discuss terms with Netero like civilized beings. Which, all things considered, was a pretty huge breakthrough.
- Especially since the last time it looked like he was having a moral crisis (because of Komugi) he turned out to be leading up to triumphant laughter over how much more marvelously powerful it meant he was, that he could kill and eat any human despite our newly recognized tremendous variety of potential.
- Too bad Netero was determined to stick with the blowing up plan. On the other hand, Meryem is the scariest thing ever, so I can understand the desire to try to wipe him out with no caveats.
- The Wolkenritter in Magical Girl Lyrical Nanoha A's could count. They go out to complete the Book of Darkness despite Hayate ordering them not to, which would seem to make them an example, but they do it regretfully and only because they believe it's the only way of saving her (which is not far from the truth). They go so far as to avoid killing people so that Hayate won't be responsible for murder.
- Perhaps Reinforce could also count as she, after seeing that the Wolkenritter have been absorbed into the book, targets those she thinks are responsible: Nanoha and Fate. Hayate makes it very clear that this is not what she wants.
- Kino's Journey: Kino meets a woman traveling with the intent of spreading peace, but the man she is traveling with is a highly skilled gunman. He kills people trying to attack the woman and she is none the wiser.
- Conrad Weller in Kyou Kara Maou quite frankly states that he is this to Yuuri in relation to both Greta and Hube, who respectively tried to kill Yuuri to please her racist guardians and to get Conrad to kill him, and who Yuuri wants to save and protect when they're disabled afterward. Conrad's first priority will always be Yuuri's safety, no matter how cruel he has to act.
- This is carried to its logical conclusion in the Daishimaron arc, when Conrad breaks Yuuri's heart into little pieces by coming back from apparent death as an enemy. Actually The Mole, and not an especially subtle one in some ways, but he's pretty convincing about having betrayed them, even if no one can figure why. It turns out God told him this was the best way to protect Yuuri. Really. It was part of God's plan to kill himself.
- The God in the spoiler above is Shinou, the Original King of Shin Makoku. He was slightly possessed by
the Devil Soushuu when he was still alive, and had a soul excision done to slow the infection. After four thousand years, Soushu was coming out on top and God Is Evil, but neither of them was able to have complete control, meaning they went around building one another's plans into their own so they wouldn't be haring off in opposite directions and convincing the shrine keepers that God Was Crazy. Also because they weren't really separate consciousnesses.
- In Naruto Danzo is revealed to be one to his Rival, The Third Hokage, Hiruzen Sarutobi. In an effort to keep the village safe, and prevent the idealistic Hiruzen from having to tarnish his image Danzo created Root, a Black Ops organisation that has been involved in all sorts of unpleasant business over the years, all, at least in his mind, for the good of the village.
- In Durarara!!: Izaya is revealed to be this to Shinra. How bad is Izaya willing to protect Shinra? Well it all started in middle school when a student named Nakura tried to stab Izaya after trying to bet on him and losing the money because Izaya purposely didn't succeed. Izaya didn't expect anyone to protect him because he was technically getting what he deserved which is why he panicked when Shinra jumps in the way of the knife. Izaya swears that Nakura will regret this for the rest of his life. After that, he stalks Nakura after that incident and continues to keep in touch with him in order to destroy his life when the time is right. He frames him for two major incidents at the end of the novel and outright tells him that those bosses will get him.
- Also while Jinnai ordered Ruri's stalker to attack Shinra, Izaya outright tells Celty that he doesn't care about Shinra getting stabbed again because Shinra didn't care about his recent stabbing. However, he instantly gives Celty information about Jinnai without any second thoughts because it's obvious that he wants revenge on Jinnai now.
- A lot of other Durarara characters follow this pattern too. Mikado, Kida, and Anri are all willing to be this for the naive, nice people they believe the others to be. Walker and Erika are this for Kadota, though he has some idea about what they're doing while he averts his eyes.
- Homura in Puella Magi Madoka Magica, to Madoka. She threatens to kill Mami, attempts to kill Sayaka, so that Madoka won't have to bear the pain of seeing her die or become a witch, and in fact does kill Kyubey, not that it sticks. Though, in her case she tried everything else first.
- In The Legend of the Legendary Heroes, Miran Froaude is this to King Sion Astal.
- In the Ace Attorney Investigations manga, Marco Swindell, who is extorting money out of the head doctor of the Jiffy Clinic, is found dead of poisoning. The culprit turns out to be a patient, Clive Fortuna, who decided to kill him to free Dr. Jiffy of him. Dr. Jiffy tells the culprit that he finds his devotion touching, but that his crime must be punished.
- Sensui of YuYu Hakusho is an odd subversion: due to his Black and White Insanity, he developed a new split personality each time he needed to do something he considered evil, leaving his central persona pure.
- Johnny the Homicidal Maniac: NNY meets a fan who idolizes and copycats his work because he thinks it's just that cool. NNY is outraged because he doesn't kill for the fun of it — he does it because he needs the outlet to survive his role as a "Flusher" for the world's negativity. (NNY then proceeds to do to the copycat what he does to everyone.)
- Also, oddly enough, this becomes an example of Even Evil Has Standards as well. It is implied by NNY's killing rant that the impostor raped a woman, and that NNY would "never do...that". (Though, this may be more because NNY loathes physical contact than anything else.)
- Depending on who is writing, Batman is this to the Justice League, and the superhero community at large. Hard not to be when your team mates stumble across detailed plans on how to kill each and every one of them in case they go rogue and have to be put down.
- DC Comics' controversial Identity Crisis storyline turned a small group of lesser Justice League members into this for the League at large. While the Big Three heroes like Superman, Batman, and Wonder Woman went about living and acting on their ideals, lesser members would do necessary "clean-up" jobs to preserve the League's secrets, primarily by having Zatanna wipe minds and reprogram someone's personality. Used as a Retcon to explain away events where the villains learned (or should have learned) the identities of various heroes, but never acted on them.
- DC Hero team, The Outsiders. The Outsiders have had three different incarnations over the years. They were founded by Batman, whose ties to the League had become strained. He has stated his intent to use the team as a black ops version of the Justice League, able to take the proverbial "fall" in public opinion where the League cannot.
- One of the interpretations of Captain America's sidekick Bucky was as the guy who did the backstabbing Cap was too moral to do.
- Another is that Cap wasn't too moral for that kind of work, but that his public image could not be so sullied. There are several instances where Cap is portrayed as accepting, even approving, of Bucky's "extracurricular activities," although there are quite a few where he is not.
- Averted in the Ultimate universe, where Cap fights the way a real soldier would.
- The reformed Terminator Arnold Davis in The Chronicles of Utopia becomes the protagonist's right hand man when the two begin their business venture and when the main character becomes embroiled in the politics of Oerth. While the main character Asher has a fairly idealistic and positive view of people in general, Davis is far more cynical and mistrusting of mankind and plays the devil's advocate to Asher on many occasions, asking the tough questions. When Asher forms his own empire in The Chronicles of Utopia Volume II he becomes the kingdom's spymaster and head of security.
- Takashi in the Deva Series is one to Hayate, using underhanded means to protect her interests, including killing the leaders of the Circles after finding out about their plan to nuke her school.
- Connie Poirier is this to Elly Patterson in The New Retcons, enabling her to blame everyone but herself for her misfortunes, lie about having a baby out of wedlock and putting it up for adoption, and not telling Michael John's not his biological father. She is furious when Elly starts to snap out of it and realize that Connie's a Poisonous Friend, and that, combined with Woman Scorned, caused her to kill Elly.
- The BLU ponies in Waking Nightmares are trained killers with all sorts of mental hangups (Medic proudly admits to being a dedicated sadist, Sniper and Spy bring up their skills at assassintion with pride, and Pyro... well.) but they are wholly dedicated to protecting their new Ponyville friends, and their dangerous skills are needed against the growing threats. It still makes the others a bit uncomfortable when they're reminded.
- Dolores Umbridge in Harry Potter And The Order Of The Phoenix knows that Cornelius Fudge would never permit her to use the torturous Cruciatus Curse to get information out of Harry and his friends, but as she says, "What Cornelius doesn't know won't hurt him." Even the book synopsis on the dust cover describes Umbridge as having "a personality like poisoned honey."
- Or maybe it just becomes "what Cornelius doesn't know can't be linked to him by the press and force him to resign".
- The secret of Dumbledore's childhood: his poisonous (boy)friend Gellert Grindlewald.
- In a more complex way, and probably not intentionally, it's Snape for Dumbledore, being the Bad Teacher for Harry (Dumbledore obviously being the good one). His constant nitpicking, bickering and sneers served to harden Harry's spirit and supposedly not to get a swelled head. Not that it was pleasant, or remotely useful, given that Harry hated the fame from the beginning and already had to go through the traumatic experience of being a murder target almost every year.
- Not that it was successful, either, since not only did Harry already arrive at the school detesting excessive fame and attention thanks to the Dursleys' treatment, Snape's treatment also caused Harry to constantly suspect Snape of evil through all of the books, which almost allowed Voldemort to win several times (a notable example being the first book, where Harry attempting to prove the wrong person guilty gave the real Voldemort ally too big of a lead).
- The Biblical figure of Joab in Second Samuel. As King David's general he frequently performs David's dirty work including orchestrating the death of Uriah the Hittite (on David's orders) so David may marry Uriah's widow, Bathsheba, and executing David's son Absalom for rebellion, against David's orders. While Absalom's death enables David to remain king, David publicly mourns for Absalom, and eventually orders Joab to be killed.
- Even then, David didn't technically give the order. Solomon gave the order on his behalf, after yet another betrayal and David confiding in him about Joab's past actions.
- For another poisonous friend in the Bible, try Jezebel. She led Ahab to worship false gods, and had the prophets of the God of Israel killed, as well as those who worshiped the true God. After several years of perversions, lies and murder, things eventually came to a head. Her husband (and the King of Israel), Ahab, wanted the vineyard of Naboth. Naboth refused to sell, despite good offers of money and better land elsewhere. Jezebel had Naboth killed on trumped-up charges of blasphemy against God and the King, thanks to two false witnesses she paid off.
- God sent Elijah to talk to Ahab, as he went to take Naboth's field. Elijah cursed Ahab and Jezebel as enemies of God: both were eventually killed, Ahab in battle, and Jezebel by being tossed out of the window.
- In Patrick OíBrianís Aubrey-Maturin novels, the dual protagonists are frequently each otherís poisonous friend: each man has been known to aid his dearest friendís missions by conducting hostilities in ways that are appalling to the latterís sensibilities or morality—the swashbuckling captain Jack Aubrey with large-scale naval carnage, the surgeon/intelligence agent Stephen Maturin with cold-blooded assassination and deception.
- The novel Shady Corners by Mathew Williams has a Poisonous Friend as the protagonist. It's every bit as creepy a read as you'd expect.
- In The Baby-Sitters Club, Ashley, who encouraged Claudia to leave the club and spend more time on her artwork. Also the "bad girls" group that Stacey falls in with later in the series.
- In The General, Suzette, Lady Whitehall. Wife of the straightforward and honest Raj Whitehall, who survives the Byzantine machinations of the Governor's court despite his total lack of aptitude for such things... because Suzette is entirely happy to seduce and manipulate his rivals, poison his enemies, and arrange for obstructionist officials to be quietly dropped into the river with a sixty-kilo roundshot chained to their ankles. All without telling him. Disturbing because he is WELL AWARE of what she is doing and yet is on occasion preachy about the morality of doing it.
- The whole purpose of Contact's Special Circumstances division.
- Rare protagonist example: Harry Dresden to Michael Carpenter, his good friend, who is a (literal) Knight in Shining Armor and has an uncompromisable code. So, in Death Masks, he asks Michael to leave the room while he breaks the legs of Quintus Cassius.
- And then Ebenezar is something of a Papa Wolf Poisonous Friend to Harry. Russian Satellite, anyone?
- Harry didn't appear to have any problem with the Satellite, it was the revelation that Ebenezar was actually a Black Ops Assassin that pushed him (temporarily) into Poisonous Friend status.
- Lasciel acts like a poisonous friend to her hosts in order to corrupt them.
- Perrin's loving girlfriend and wife Faile in The Wheel of Time. Besides being a very jealous type and giving him a hard time over any woman she suspects might want him, she also indulges in all the dirty aspects of politics he considers to be wrong, including sabotage, espionage, manipulation and assassination. Some of those things he tells her not to do, but she doesn't listen. The rest, he just doesn't know about...
- That's doubtful, as he knew the type of woman he married, especially after meeting her parents. It's more of a contrived ignorance, as he is very aware of just how ruthless she can be. It's more that he knows better than to ask as he would probably not like the answer.
- The Gentleman with the Thistledown Hair in Jonathan Strange & Mr Norrell gets it into his head that working as a butler constitutes abuse for Stephen Black, and decides that because he's handsome and courteous, he needs to be king of something. He even tries to get him to kill the king of England for this reason, and Stephen has to explain that it doesn't work like that.
- There's a dark sort of Overly-Long Gag late in the book where The Gentleman tells Stephen a rambling story of the lengths he went through to find Stephen's "true" name and the many people he ended up murdering directly or indirectly in the process.
- Vimes and Vetinari in Discworld. Unusual in that the Poisonous Friend is actually the protagonist's boss.
- Vimes's butler Willikins is this to Vimes. He has been for a long time, but as of Snuff! he identifies as such.
- Lord Montfallcon does this for a living in Gloriana by Michael Moorcock, working behind the scenes to maintain order because he fears his queen's idealistic policies aren't enough to secure the realm's new golden age.
- Valentinian in Belisarius Series has some aspects of this; not only is he Belisarius' bodyguard, he is his personal executioner and hatchet man. When Belisarius wants some shocking bit of violence done he simply says "Valentinian..." which is shorthand for Off with His Head!.
- Monk Mayfair is just short of this to Doc Savage. Philip Jose Farmer theorizes that in addition to Savage needing someone who can kill (and lie, steal and seduce), Mayfair's obvious enjoyment of these gives Savage vicarious pleasure.
- The Knight and Rogue Series has a mild example in Fisk. While Michael is so righteous that he won't even tell a white lie, and encourages Fisk to follow this example, Fisk is willing to lie or con his way out of a situation when need be-usually when Michael isn't looking. He becomes less of one by the third book, though.
- The Corrupt Corporate Executive Cassandra Cautery is all kinds of this to Dr. Charles Neumann in Max Barry's Machine Man. She claims to have his best interests at heart, but is clearly only looking out for Better Future.
- Stephen King's thriller Thinner gives us an anti-heroic example: Protagonist Billy Halleck is cursed to die by a pack of traveling Gypsies after accidentally killing the leader's daughter. Billy's best friend, mafioso Richie Ginelli, responds by poisoning their guard dogs, shooting up their camp (without killing anyone), and assaulting the clan leader's granddaughter. The old leader takes the curse off, but Ginelli is killed by said granddaughter in the end.
- From the novel Surrender, Finnegan is this to Gabriel.
Live Action TV
- Bebe on Frasier was a classic example of this: the completely unscrupulous agent. Frasier was frequently warned that agreeing to anything she suggested, however favourable and seemingly innocent, was tantamount to dealing with Satan.
Frasier: What kind of a woman are you? You seduced me, you lied to me, you nearly got me killed. You've shamelessly manipulated not only me but the station, the news media, and the entire city of Seattle. What do you have to say for yourself?
Bebe: Aren't you glad I'm on your side?
- Saul Tigh on the 2000s Battlestar Galactica. He's best friend to Commander/Admiral Bill Adama (Galactica's resident beloved leader). He's usually the guy rooting for a good fight rather than diplomacy, and occasionally, is right in doing so. But he's a liability. Time after time after frackin' time, Adama goes out on a limb for Tigh - hiding the truth of his alcoholism, appointing him XO even though he's "not cut out for command", and whitewashing, then forgiving, most of Tigh's screwups (including shooting civilians aboard the Gideon, a military dictatorship, the use of suicide bombers on New Caprica, and showing up drunk to testify at Baltar's trial). Though he occasionally has to Shoot the Dog to keep the blood off Adama's hands (see the entire New Caprica arc and the S3 episode "Hero"), one shudders to think how far a Saul Tigh who's realized he is, in fact, the very thing he's been fighting for so long will go in the service of Bill Adama. He's doing a surprisingly good job, but the season's only half over.
- In an odd case, Tigh himself has his wife Ellen, who encourages his alcoholism and tries to get him to be more assertive and ambitious. And betrays resistance plans to the Cylons to keep him alive. However all of this is now in the past tense as he poisoned her for this last. Supposedly someone else in the resistance would have done something worse to her otherwise.
- He is this way up until he learns that he is a cylon. It is very likely his destructive behavior and drinking were his way of internally dealing with his "sleeper" status, and keep himself from doing something fatal to Galactica and Adama, but YMMV...
- In Star Trek, "Section 31" performs questionable actions in (preemptive) defense of the Federation. Played with a bit, as when they first surfaced in Deep Space Nine the Federation was actively trying to shut them down; Enterprise sort-of retconned them into originally being the black-ops wing of Starfleet Intelligence, and apparently losing their budget and official status at some point seems not to have slowed them down much.
- Tuvok cites this trope as his reason for secretly betraying Captain Janeway in an early episode of Star Trek: Voyager, saying that his role requires making the morally dubious choices she can't make in order to get the crew home. She doesn't take it well.
- Section 31's official status is also listed in the non-canon Section 31 novels, where Kirk carefully reads the Starfleet Charter and locates Article 14, Section 31, which is a short clause allowing for the creation of an unspecified agency with unspecified powers to safeguard humanity.
- Doctor Who:
- Leela has no qualms about violently disposing of anything or anyone that threatens the Doctor, despite his many attempts to rein her in.
- Captain Jack Harkness is willing to go quite far to protect the Doctor, using methods that the Doctor would never approve of.
- River Song takes this trope Up to Eleven, willing to let time itself be destroyed just to keep the Doctor alive. It frustrates him terribly. On the the other hand, he does admit that her methods are useful at times:
The Doctor: Oh, and this is my friend River. Nice hair, clever, has her own gun. Oh, and unlike me, she really doesn't mind shooting people. I shouldn't like that. Kinda do, a bit.
Thank you, Sweetie.
- Neatly summarized when River faces a Dalek:
Dalek: Records indicate you will show mercy. You are an associate of the Doctor.
River: I'm River Song. Check your records again.
- Buffy the Vampire Slayer: Giles on several occasions, in particular beating the crap out of Ethan in "Halloween", killing Ben in "The Gift", and plotting with Robin to kill Spike in "Lies My Parents Told Me". And sending Faith to kill Gigi in the Season Eight comics.
- He even gives a nice speech about it in "The Gift".
- Really, all of the cast for both shows are this for all the others (besides for Dawn, Tara and Lorne). We've seen them all without the others (Wishverse Buffy, Dark Willow, Ripper, Angel after firing everyone and a few others) and they're all much, much worse without the others. So it's like Conservation of Ninjutsu, only with evil.
- In a subversion, when Fred plans to murder (Or at least trap inter-dimensionally, which probably a death sentence) her old college professor, who did the same to her and at least four other people, her boyfriend Gunn kills him for her, in an attempt to pull this off. Fred does not take this well at all.
- This was on Angel. Another example would be Wesley shooting Knox in cold blood right after Angel gives a speech to him about being merciful to their enemies.
Angel: "Were you even listening?"
- On Charmed, Cole kills a corrupt landlord who is trying to blackmail Phoebe. This is a turning point in one of his several backslidings into evil.
- Burn Notice plays with this trope. Michael is hardly a boy scout himself, but it's implied in several episodes that hanging out with a Handsome Lech FBI informant and Ax-Crazy arms dealer and former IRA terrorist are not exactly helping his standing with the intelligence community.
- Conversely, Sam and Fi are portrayed as good influences compared to some of the people Michael has had to get into bed with in the course of investigating the people who burned him. A particularly strong example is Larry, Michael's former mentor-turned-Psycho for Hire Professional Killer, who's always showing up trying to convince Michael to join him. In a sort of inversion, Larry thinks that Michael's true potential is being stifled by his association with his present comrades.
- The Good Wife includes Fred Weller guest starring as a jerkass Amoral Attorney. It's implied he acts this way in part because he believes his boss deserves someone watching his back and willing to get their hands dirty. Good thing, too, because it was the only thing giving his character depth. Too bad his boss doesn't deserve it . . .
- On Luther, the eponymous Scotland Yard detective has Alice Morgan, a former Child Prodigy who brutally murdered her parents and got away with it, and has now developed a crush on the copper who investigated the case. Luther really doesn't appreciate her attempts to help him get back together with his estranged wife, which seems to involve a lot of breaking and entering and assault.
- Walter White is this to Jesse Pinkman in Breaking Bad. While Jesse wasn't completely innocent before getting into business with Walt, it's undeniable that his life has taken a definite turn for the worse because of Walt's influence. Walt even manages to manipulate Jesse into killing a man in cold blood. Jesse is equally as poisonous to Walt, but unintentionally, and in a completely different way: while his sincerity might be debatable, we continue to see Walt goes to impressive lows in order to ensure Jesse's safety, despite the fact that he is an emotionally volatile wild card and a liability. Add this to the fact that Jesse is the one who gets Walt into the drug business in the first place, and you have a recipe for one of the most mutually poisonous friendships on television.
- Community Jeff's friend Alan. Even after Jeff helps him become a partner in the firm, Alan still won't admit that he was the one that got Jeff disbarred.
- Revenge has Nolan, who's actually an inversion of sorts: while he assists Emily Thorne in her titular revenge gladly and is significantly more cynical than she is, he also frequently points out she could easily just go off to enjoy her life and leave the people who wronged her behind.
- The Criminal Minds episode "The Performer" has the unsub turn out to be Dante/Davies's manager using an obsessed, schizophrenic fangirl to murder other fans to get publicity for his new album. Davies is quite horrified at this.
- In an interesting Sitcom variant, Lily from How I Met Your Mother is revealed to be this, breaking up Ted's girlfriends if she thinks that it will be better for Ted (and, by extension, herself).
- Damon of The Vampire Diaries can sometimes fall into this role, particularly in regards to protecting Elena. He's outright stated that he will do whatever he has to do in order to keep her safe, even if she hates him for it.
- Scandal: President Fitzgerald Grant, to Olivia.
- Lampshaded, doubly-subverted, deconstructed, and mixed in with a little Psycho Supporter in Brink. The Resistance has some rather extreme followers who are willing to do ''anything'' if they think it will help Brother Chen and the Resistance. At one point, one of them says that they will do the dirty work while Brother Chen, the much more reasonable leader of the Resistance, will be able to keep his hands clean. The subversion comes when Chen mostly tolerates such soldiers, since he sees them as necessary for the war effort and for his political promotion. Its deconstructed through Moekena, who looks at Chen and the radical followers and sees a vile leader who uses others so that he doesn't get his hands dirty instead of seeing a conflicted leader who has to deal with dangerously extreme but necessary followers, since Moekena does not know of Chen's point of view. Its doubly subverted when Chen yells at the radical followers in rage once they attempt to cover (or succeed in covering) the Ark in nuclear fallout for him in a What-If mission, calling the radicals idiots and rebuking them for not realizing that he was bluffing.
- Princess Sapphire has some interesting ideas on how she should help Almaz once she learns of his predicament. Most of them involve killing someone, as almost all of her ideas do.
- Soren in Fire Emblem: Path of Radiance toes the line of this, acting as Ike's second in command and advisor. Cold, hyperrational, and only caring about Ike, he discourages the more sentimental decisions. But he doesn't take this trope to its fullest extent, as he doesn't make any unsavory choices behind Ike's back.
- Axel to Roxas in Kingdom Hearts. He seems like a pretty cool guy, but a single playthrough of Chain of Memories is more than enough to see how wickedly treacherous he can be, and he shows it off more towards the end of 358/2 Days. Obsessed with keeping Roxas and Xion as his friends, he lies to them, does questionable stuff behind their backs, and if they try to leave the Organization of their own free will, he attempts to bring them back by force for selfish reasons. Roxas does wise up near the end and replies in kind by leaving. Axel does redeem himself in the end though, but Redemption Equals Death. In 358/2 days and the prologue of Kingdom Hearts II, he's a prime example of a Knight Templar Big Brother. Only he's not quite dead, and returns in Dream Drop Distance as Lea, his somebody and preforms a full Heel-Face Turn, even getting his own keyblade.
- Mithos is a poisonous brother of Martel in Tales of Symphonia, whose misinterpretation of Martel's wish for a discrimination-free world leads to him attempting to execute an Assimilation Plot.
- Sodia from Tales of Vesperia. She tries to murder Yuri, whom she perceives as Flynn's poisonous friend.
- World of Warcraft:
- Makuru is one to Obadei, insisting on taking vengeance against the orcs after learning that they killed Obadei's brother.
- In Mists of Pandaria, Wrathion is shaping up to be this. He believes the Burning Legion will eventually invade Azeroth, so the Alliance/Horde war must end so that Azeroth can put up a unified front against the threat. However, being a black dragon, Wrathion's idea of world peace involves one of the two factions conquering the other. Pretty much everyone else who meets him agrees that Wrathion should not be trusted.
- In Dragon Age: Origins, Morrigan kind of fits this since she approves of the Warden's more ruthless actions and dislikes his/her more compassionate ones. A better example appears on the antagonists' side: Arl Howe to Teryn Loghain. Arl Howe does seem genuinely loyal to Loghain and his political and military support is a great boon to him as well. However, Loghain supporting him and making him Arl of Denerim will help to screw him over in the Landsmeet if you bring up some of Howe's actions like kidnapping and torturing the son of another noble.
- Kreia in Knights Of The Old Republic II The Sith Lords qualifies. She has an obsessive and controlling attitude toward your character, vehemently opposing the addition of most of your party members and any associations with NPCs who seem to threaten her hold on you. One major difference is that, rather than try to keep you pure, the lessons she imparts to you as your mentor are usually geared toward you becoming a Manipulative Bastard: in conversation, a manipulative response that takes long-term goals into consideration is usually the way to make her happy. Bonus points if you choose The Dark Side, as most of your party members who care enough about you to try to intervene attribute it to Kreia's bad influence on you.
- Depending on how moral you want to play it, Steven Heck is this to Mike in Alpha Protocol, murdering and framing innocents to help his buddy.
- In Disgaea 4, Fenrich vowed to make the vampire tyrant Valvatorez the greatest in all the Netherworld. The only problem? Somewhere along the line, Val seems to have developed some sort of pesky conscience, has sworn off human blood (which has massively De Powered him), and has insisted on following a new code of evil which is not very evil at all. Fenrich has no intention of giving up his original vow, so...
- Some of Fenrich's ideas tend to cross a few moral lines (but never THAT one, thankfully). During Chapter 5, he goads Valvatorez into promising him that he will take down Vulcanus should she pose an obstacle to their plans... and then goading her into a fight with them by blowing their bounty out of proportion. Right in front of Valvatorez!
- In the first God of War, Ares honestly seems to think he did Kratos a favor when he tricked him into murdering his own family. During their final battle, Ares throws a fit and claims that Kratos had no right to turn against Ares after everything Ares did to make him stronger. At the end when Kratos has Ares at his mercy, Ares makes one last plea for his life by telling Kratos that he just wanted to make Kratos a great warrior. Unfortunately for Ares, he succeeded.
- Mass Effect:
- Commander Shepard is accused of being one, albeit unintentionally, by Admiral Rael'Zorah in Mass Effect 2 due to Shepard's return for the dead causing his daughter, Tali, to nearly immediately file a transfer request to join them on what is essentially a suicide mission.
- Matriarch Aethyta gets in on this in Mass Effect 3, noting that Shepard's influence has lead to Liara dealing with some severely sketchy people in the last 3 years. Considering Liara spent the past 50 years beforehand as an archaeologist working alone on dig-sites, which Liara herself noted have less explosions, Aethyta definitely has a point.
- Introduced in Dynasty Warriors 8, Jia Chong is this to the easygoing Sima Zhao. It's made quite explicit - while Sima Zhao looks (and acts) like a Californian surfer transposed into ancient china, Jia Chong is pale as death with hair as black as night. Several soldiers refer to the two as being 'like light and shadow'. Jia Chong repeatedly takes action to benefit Sima Zhao, usually without bothering to check with him first, and is particularly swift to kill off enemies that Sima Zhao seems inclined to offer mercy to. Culminating in...
Sima Zhao: (Standing with his sword raised over the Wei Emperor) This is what you wanted, right Jia Chong?
Jia Chong: Yes... but you can leave the dirty work to me. (Cuts down the Emperor himself.)
- Rider is Sakura's poisonous friend in the Heaven's Feel route of Fate/stay night. She's willing to let the world be destroyed or kill Shirou and Tohsaka, her sister, just to prolong her life an extra couple days if she has to, whether Sakura wants her to or not. Eventually, she realizes that Sakura just being alive isn't sufficient, and ends up fighting against her. She's still acting almost exclusively for Sakura's benefit, though.
- Shinji, Sakura's adoptive, abusive brother is this for Shirou.
- In Hakuōki, Hijikata Toshizo intentionally takes on the role of harsh disciplinarian and "Demon Vice-Commander" to keep order within the Shinsengumi and further Commander Kondou Isami's goals against the heavy opposition of the era's very classist society, allowing Kondou to remain as nice and brotherly and idealistic as he wants to be. It's a mild example since Kondou is aware of everything Hijikata is doing, but there are points at which Hijikata is specifically noted as "playing the villain" for Kondou's sake. In the end, it kind of backfires on both of them, as Hijikata's efforts protect Kondou from many of the harsher realities of leadership and leave him unprepared to deal with the situations the Shinsengumi face after the Boshin War begins.
- Hatoful Boyfriend has two notable examples, both revealed in the much darker "Bad Boys' Love" route. Namely, Hitori Uzune's efforts to avenge (and later, keep the remains of) his brother Nageki Fujishiro, and the extremes to which Yuuya Sakazaki went to protect his brother Sakuya Shirogane Le Bel.
- Richard from Looking for Group is an extreme example. He started as an evil character who found Cale'anon (one of an unspecified "evil race" committed to truth and justice) entertaining, but found himself gradually swept up in the cause, acting as one of Cale's lieutenants. He cemented himself in this role when he was brought before a demonic court to answer for all the good he's done in aiding Cale'anon.
- Pella would be a better example, as she commits a crime to further the main character's cause.
- The trial was specifically about a particular village that he slaughtered; though he thought he was doing evil at the time, demon scryers found that had he not done so, they would have eventually become an invasion force that would subjugate the entire continent. The net moral worth of his act was therefore deemed "good" and he was, essentially, on trial for neglectful virtue.
- Home Stuck has a couple, given the massive cast of eclectic characters:
- A mild example in the Peregrine Mendicant, who despite beginning her career as a meek postal worker on Prospit becomes a sword-wielding Action Girl. This contrasts with the Wayward Vagabond, who leans more towards pacifism (at least when he's not leading a rebellion of the common chess piece against their monarchs). This comes to a head when PM takes up the power of the White Queen's ring, which WV had ample opportunity to do but clearly couldn't stomach the idea of becoming like Jack Noir.
- The Trolls' group had more than their fair share of less ethical members, which is saying something given that all of them were imperfect to varying degrees. Specific examples include Vriska, Gamzee, and Eridan. Unsurprisingly, they are the three who end up killing at least one of their friends each.
- PeeJee and Aubrey fit this trope for Davan of Something Positive. Hurt Davan in any way and they will respond with tenfold the pain you caused him. Davan is not always bothered by this.
- In Men In Hats, Aram attacks Sam with a steamroller in the name of putting Gamal's plans into action, and Gamal is pretty sure steamrolling people wasn't his idea. (Aram has also been known to poison his friends.)
- In El Goonish Shive, Nioi acts on the assumption that Lord Tedd would be better off without his personal Blood Knight. In turn, General Shade Tail's opinion of Nioi is pretty low.
- Anakin becomes this for Palpatine in Darths & Droids.
- Firefly Cross has a fairly low-key (so far) example; Katyn's friend Micah is actually Dark, and willing to kill in order to protect her. Which he's already done, when a Well-Intentioned Extremist stole her sword.
- In The Order of the Stick, Tarquin does seem to genuinely love Elan, but he expresses it in truly awful ways. He wants Elan to be happy with Haley...so he frames Haley's father for murder as a "test" to see whether she deserves Elan. He wants Elan to grow into the role of The Hero instead of remaining a supporting character...so he orders his army to kill the actual Hero Roy. On the other hand, being Tarquin's enemy is even worse which Nale found out the hard way.
- In Worm, Token Evil Teammate Regent, realizing that Sociopathic Hero Shadow Stalker isn't going to leave the Undersiders alone and will in fact keep coming after them with lethal force until she gets lucky, takes it upon himself to use his People Puppets power to utterly destroy her life and drive her out of town, refraining from killing her only because it would be more troublesome and draw more attention from the authorities.
- Beezy J. Heinous on Jimmy Two-Shoes. In His Friend Versus Lover rivalry with Heloise over Jimmy, he can get just as yandere as she can (see: "Best Bud Battle"). He has also stolen money from Jimmy at one point.
- Dale Gribble on King of the Hill is the trademark Poisonous Friend. Betrays his friends at the drop of a hat, destroys their property without warning, mocks and belittles them behind their backs (especially Bill, usually FACING Bill for each mocking). Even after he ruins Hank's new lawn after spreading fire ants there, even after digging under Hank's house to create a tunnel and then suing Hank so he has to go to Anger Management, there is absolutely no reason why anyone would want to be friends with the little wierdo.
- In American Dad!, Roger started out as this towards Steve, but has since shifted this towards Stan instead.
- Perhaps a real-world example would be an aide to President Theodore Roosevelt, who was said to have shot the famous bear spared by the president.
- The bear had already been chased down, clubbed into submission and tied up. Roosevelt refused to take such an unsporting potshot, and asked an assistant to put the bear out of its misery.
- Some claim that most of Barack Obama's cabinet are of this ilk, getting down and dirty in debates and issues so he doesn't have to come off as a jerk. Particularly true of Rahm Emanuel, notorious for being Obama's hardass attack dog (even following a Congressman into the shower to help secure his vote). If an American version of The Thick of It were to be made, the Transatlantic Equivalent of Malcolm Tucker would probably take heavily after him (it helps that Emanuel even kinda-sorta looks like Peter Capaldi). Emanuel is now Mayor of Chicago, so said adaptation would have to be a bit unrealistic... As it is, when the actual adaptation was made, it appears that the team noticed American politics goes in less for bollocking and more for biting sarcasm—to say nothing of the fact that Washington offices tend to be loaded with young staffers—and the role of "guy who transmits orders from On High" went to a schlubby twentysomething instead.
- Gaius Scribonius Curio, and to an extent Marcus Antonius, were poisonous friends to Gaius Julius Caesar during the political conflicts leading to the civil war and during the civil war. They would often give a far more aggressive image of Caesar and his motives, probably in their part contributing to the eruption of the civil war. On one occasion, Curio told someone who wasn't decided on who to join in the war that Caesar's thus far merciful and gentle attitude toward conquered (Roman) enemies and encountered neutrals was just for the moment, and soon his (Caesar's) cruel nature would emerge from the facade. This was completely contrary to what Caesar liked to present himself being like, writing to Cicero that "Nothing is more alien to my nature than cruelty." (Gauls would disagree.) In the times leading to the civil war, Curio would insinuate that Caesar was ready to start a war if his requirements (a consulship following directly after his proconsulship in Gaul) weren't met. This only added fuel to the flame for his enemies, who saw that as long as it was Caesar who would start the war, they'd gladly join the fight and no doubt win. In fact, a lot of Caesar's political allies had a very similar mindset, and neither Caesar nor Pompey actually wanted to go to war, though they were absolutely prepared for it.
- Many a member of [[insert name of website here]] fits comfortably in this trope. You know the type: they sincerely do care about the site and want to contribute, but are either so bad at it or so stubborn and opinionated that they come off as a Troll. See: That Troper..
