History EvilIsNotAToy / LiveActionTV

** In the last season, Kai Winn joins with Gul Dukat to free the pa wraiths (Bajoran devils) sealed deep inside the planet. While Dukat was insane and knew ''[[OmnicidalManiac exactly]]'' what he was getting into (hell, they went so far as to empower him), Winn figured she could control both the Pah Wraiths ''and'' Dukat. It ended about as well as you would expect.

* In ''Film/CastADeadlySpell'' where the villain attempts to release the Great Old Ones into the world. Guess [[spoiler: he should have made sure he used a real virgin]].
* A demon in ''Series/{{Charmed|1998}}'' freed the Titans in order to take control of the Underworld. He doesn't even finish his MotiveRant before they kill him out of annoyance.

** Inverted when an already free demon possesses a boy, expecting to use him as a host. The boy turns out to be EvilerThanThou, and the demon finds himself trapped inside.
** Played straight when Gunn attempts to get help from the conduit to the Senior Partners in "A Hole in the World", only to get a NoHoldsBarredBeatdown:
--->'''Conduit''': This is the part where I need to be clear. I am not your friend. I am not your flunky. I am your conduit to the Senior Partners, and they are tired of your insolence. Oh, yeah. They are not here for your convenience.

** [[Recap/DoctorWhoS27E6Dalek "Dalek"]]: American billionaire Henry van Statten has a secret museum full of alien artifacts, with the prize of the collection being the one living specimen — a Dalek (initially damaged). After the Doctor arrives and discovers what van Statten's precious "Metaltron" is, van Statten continues to consider it the prize of his collection even after it breaks out and goes on a rampage through the facility.

** Something of a heroic example with Janeway's attempt to [[EnemyMine ally with the Borg against Species 8472]]. Thankfully, the crew was smart enough to prepare for the Borg's inevitable betrayal.
** While on a temporary stay on the ship, Q Junior decides to test the crew's abilities by magicking up three Borg cubes for them to fight. It only lasts a few brief minutes before daddy Q shows up, rescues them, and proceeds to tear into his son for being so foolish as to casually antagonize the Borg. [[{{Hypocrite}} This being the same Q that casually antagonized the Borg way back on TNG.]]

** The major example is apparently [[spoiler: Lucifer, who according to Crowley would have destroyed the demons who believed they had finally freed their "god" as soon as he no longer needed them]].
** In "Malleus Maleficarum" a group of housewives turn to witchcraft to better their lives. They are horrified to learn that in doing they so they made a pact with a demon and damned their souls to hell. The demon possesses one [[spoiler: and murders all the others when they either make too big of a scene, annoy her, or turn on her]].

** VERY MUCH the case for [[spoiler: Castiel at the beginning of Season 7. He sucked in every soul from Purgatory to make himself powerful enough to kill Raphael, declared himself [[AGodAmI the new God]], and lasted a VERY short amount of time (hard to tell exactly in-universe, a few days probably, weeks at most, less than a full episode), and proceeded to get taken over and [[YourHeadAsplode blown up from inside]] by the ancient race of evil that had been sealed in Purgatory]].
** In "A Little Slice of Kevin", Linda Tran makes the ''horrible'' mistake of trusting a witch to help them fight demons, who immediately betrays them to Crowley. Said witch also makes the mistake of irritating Crowley, the new King of Hell, who responds by vanishing her away somewhere with a flick of his wrist. The episode never clarifies what happened to her, but knowing Crowley, she probably didn't end up somewhere pleasant.
** In season 11, Crowley [[spoiler:takes in the child incarnation of Amara the Darkness — ''the'' primordial evil of the setting which frightens even the likes of Lucifer and Michael — and feeds her souls in a bid to get on her good side and manipulate her]]. By the end of the episode "Bad Seed", [[spoiler:she's become an adolescent and she wants even more souls]] and it starts to dawn on Crowley that he can't keep up with her demands. A few episodes later [[spoiler:and Amara has completely broken free of Crowley's control, only sparing him because he's NotWorthKilling]].
** Crowley does it again in Season 12. [[spoiler: Instead of having Lucifer returned to his cage (where he'd be no threat), Crowley has him chained up in his throne room and boasts about how he will break Lucifer's will and reduce him to an attack dog. Unsurprisingly, this backfires horribly]].
* Horton Rivers from the ''Series/TalesFromTheCrypt'' episode "Television Terror" takes his television crew to an abandoned but allegedly HauntedHouse for thrills and ratings. The ghosts are all the more happy (or angry) to oblige them. [[GoneHorriblyRight The segment does bring big ratings, but Horton ends up being disemboweled and hung for his trouble, with his cameraman being killed shortly before Horton dies.]]
* In ''Series/TheShannaraChronicles'' [[AntiHero Bandon]] resurrects the mysterious Warlock Lord. He's hoping the Warlock Lord will resurrect his girlfriend, and fight against the [[WellIntentionedExtremist Crimson]] who are oppressing magic-users. Bandon does promise to serve the Warlock Lord, of course. The Warlock Lord [[OneManArmy is a lone wolf, however]]. [[spoiler: Bandon sees his revived girlfriend get {{Mind Rape}}d, mercy-kills her, and then gets his ass kicked]].

* In ''Series/TheXFiles'' episode "Die Hand die Verletzt" a small town Satanic cult has been going a bit light on their worship lately, offering maybe token prayers. Then one of their kids actually summons the Devil. People die.

** In ''Series/KamenRiderGhost'', [[EvilPrince Adel]] abuses the power of the Ganmaizers after inheriting the ability to control them, unaware that the reason his father avoided using them was because their ResurrectiveImmortality caused them to grow both stronger and ''smarter'' after every use. They gradually go from mindless homunculi, whose prime directive is to prevent anyone from accessing the Great Eye, to a fully intelligent HiveMind who conclude [[KillEmAll the best way to do that is to make sure there's nobody around left to try]].

* In ''Series/PowerRangersDinoFury'', the Sporix Reghoul decides the best thing to do is to [[spoiler: ''resurrect Lord Zedd'']] with the only thing keeping him in check is a [[Series/PowerRangersBeastMorphers Compliance Collar]]. The moment Ollie is able to destroy the Compliance Collar, the first thing [[spoiler:Zedd]] decides to do is try to murder Reghoul before focusing on two Sporix that were still around once Reghoul escapes.

** ''Series/KamenRiderRyuki'':
*** Bratty upperclass twit Jun Shibaura thought he can put Takeshi Asakur, an honest to whatever AxeCrazy BloodKnight, against the other riders for funzies. Unfortunately, Asakura's idea of [[ForTheEvulz fun]] not only differed, but he didn't have any reason to follow Shibaura's plan. To say that things had not gone well afterwards would be a massive understatement.
*** ''Ryuki'' also provides example of a rare case of realizing the trope in time to act accordingly. [[TheStoic Ren]] [[HiddenHeartOfGold Akiyama]] had partnered with Asakura because he wanted to at least pretend to be like him, so the Rider War wouldn't pain him as much. He realized that the guy is just too evil for anyone to deal with and ditches him before he ends like Shibaura.
** ''Series/KamenRiderOOO'' has a BlackComedy example with a monster on receiving side and a human being the ''evil''. [[TheChessmaster Kazari]], while otherwise smart and capable, very understimated and misjudged just how evil could [[MadScientist Doctor Maki]] be. He never thought that Maki could come up with any way to backstab him. [[spoiler: When that happened, noone mourned Kazari in the slightest because even other [[MonsterOfTheWeek Greeed]] hated him with passion.]]

** In ''Series/KamenRiderGaim'', Mitsuzane considers himself TheChessmaster and regularly brokers deals with the villains for his own ends, but has blinded himself to the fact that they're not the pawns he thinks they are. The villains, for their part, are amused by this and play along. Things finally come crashing down on Mitsuzane at the end of the series, where [[spoiler:he makes a deal with Ryoma to save Mai's life -- and Ryoma doesn't bother to hold up his end. Ryoma gives a TheReasonYouSuckSpeech where he lampshades just how ''stupid'' it was to trust him, given how Mitsuzane knew what he wanted and what he was capable of.]]
** ''Series/KamenRiderDrive'': This show has zig-zagged the trope a bit. While [[KillerRobot Roidmudes]] are perfectly capable of wreaking chaos on their own, there are rare occassions where they make a deal with humans into fufilling whatever desires they have (i.e, using their powers to cause buildings to collapse or cause explosions by firing near-invisible projectiles at object). Of course, the Roidmude will eventually turn on the human they made the deal with and [[YouHaveOutlivedYourUsefulness dispose of them]], making said human [[MyGodWhatHaveIDone regret ever going along with their plans from the get-go.]]
** ''Series/KamenRiderGhost'': Improper knowledge of the true scope of their power and thinking led [[EvilPrince Adel]] to think he can bend the [[SealedEvilInACan Ganmaizers]] to his will. He only realized that they answered to him largely to advance their own existence when it was too late and he saw that his world has crumbled.
** ''Series/KamenRiderExAid'':
*** [[ConsummateLiar Kiriya Kujo]] failed to see that he can blackmail [[MadScientist Kuroto]] [[EvilerThanThou Dan]] only because the latter still needs him. When he crosses the line one last time, Kuroto hands him a DeadlyUpgrade which kills him.
*** A bit of {{Irony}} comes in after Kuroto falls for the same thing. He never thought that [[BadBoss mistreating]] his partner-in-crime could derail his plans in any way. Unfortunately, said accomplice happened to be Parado, the de facto leader of [[MonsterOfTheWeek Bugsters]], [[spoiler:who proves him wrong by [[BadGuysDoTheDirtyWork killing him.]] ]]
*** Kuroto delivers this again in the second ''Another Ending'' movie. [[MadScientistsBeautifulDaughter Saiko]] [[DaddysLittleVillain Yaotome]] clearly didn't know anything about his [[HeadsIWinTailsYouLose schemes]] or insanity and [[IdiotBall really]] [[HorribleJudgeOfCharacter thought]] that he wants to go through with her plan. He used her as stepping stone in his own plan and rubbed it in her face because going to cause yet another apocalypse.
** ''Series/KamenRiderBuild'': Juzaburo Nanba is too blinded by greed to see the problems with working with Blood Stalk/[[spoiler:Evolt]]. While all the other villains have the excuse of being driven power-mad by the Pandora Box, Nanba does not have such an excuse. And yet, despite being aware of Stalk's ChronicBackstabbingDisorder and [[spoiler:that he's actually an alien who destroyed at least one civilization]], he still thinks that he can keep him under control. [[spoiler:Unsurprisingly, as soon as Evolt achieves his ultimate form, he decides he has no more need for Nanba, especially since he now has shapeshifting powers for impersonations, and kills him.]]
** ''Series/KamenRiderZiO'':
*** Yuko Kitajima/Another Kiva got on a power trip after getting her powers and learned the consequences of going against the Time Jackers the hard way. [[spoiler:Ora killed her largely out of spite for being a pain in the bum and [[BeautyIsNeverTarnished ruining her image]].]]
*** Swartz/[[spoiler:Another Decade]] falls headlong into this when his full plan is revealed. [[spoiler: His entire plan was to create a perfect king of time, and then steal the king's powers for himself as Another Decade. First, he can't even steal the REAL Decade's powers properly and that backfires. Second, Oma Zi-O was far too powerful for him to handle, and furious that Swartz had murdered his only friends in front of him. It does not end well for Swartz.]]

** Yapool in the ''Series/UltramanMebius'' film, ''Mebius & the Ultra Brothers''. Once Alien Nackle [[spoiler:(Who was part of a group of aliens with the same goal until the rest were killed by Mebius)]] succeeded in releasing him... [[spoiler: Yapool kills him shortly after, having no need for him anymore]].
** Seen again the ''Series/UltraGalaxyMegaMonsterBattle'' film, when Alien Zarab releases the genuinely EVIL Ultra, Ultraman Belial from a space prison and presents him with a weapon that can control 100 monsters. [[spoiler:Belial immediately kills Zarab shortly after, not wanting to form an alliance with anyone.]]

*** [[ConsummateLiar Kiriya Kujo]] failed to see that he can blackmail [[MadScientist Kuroto]] [[EvilerThanThou Dan]] only because the latter still needs him. When he crosses the line one last time, Kuroto gives him a Game Over.
*** A bit of BlackComedy comes in after Kuroto falls for the same thing. He never thought that [[BadBoss mistreating]] his partner-in-crime could derail his plans in any way. Unfortunately, said accomplice happened to be Parado, the de facto leader of [[MonsterOfTheWeek Bugsters]], [[spoiler:who proves him wrong by [[BadGuysDoTheDirtyWork killing him.]] ]]

** Seen again the ''Series/UltraGalaxyMegaMonsterBattle'' film, when Alien Zarab releases the genuinely EVIL Ultra, Ultraman Belial from a space prison and presents him with a weapon that can control 100 monsters. [[spoiler:Belial however kills Zarab shortly after, not wanting to form an alliance with anyone..]]

** ''Ryuki'' also provides example of a rare case of realizing the trope in time to act accordingly. [[TheStoic Ren]] [[JerkassFacade Akiyama]] had partnered with Asakura because he wanted to at least pretend to be like him, so the Rider War wouldn't pain him as much. He realized that the guy is just too evil for anyone to deal with and ditches him before he ends like Shibaura.

* A demon in ''Series/{{Charmed}}'' freed the Titans in order to take control of the Underworld. He doesn't even finish his MotiveRant before they kill him out of annoyance.

* Played with in the [[PostScriptSeason Post-Script Episodes]] of ''Series/KamenRiderWizard''. Wizard gets drawn into a pocket dimension ruled by Amadam, who can control the various sources of evil power in ''Franchise/KamenRider''. Amadam also claims that [[EvilCannotComprehendGood the Kamen Riders themselves are "evil"]] (horrible at ''being'' evil, but "evil" nonetheless) since they're all {{Phlebotinum Rebel}}s that share their powers with their enemies. Unfortunately for him, once he gets the means to summon past Riders, he finds that the summoning did not give him control over them and they promptly turn on him because he's the bad guy threatening innocents. The principle that Evil is Not a Toy still holds even when that Evil fights for Good.
* ''Series/KamenRiderExAid'':
** [[ConsummateLiar Kiriya Kujo]] failed to see that he can blackmail [[MadScientist Kuroto]] [[EvilerThanThou Dan]] only because the latter still needs him. When he crosses the line one last time, Kuroto gives him a [[EverythingFades Game Over]].
** A bit of BlackComedy comes in after [[DidntThinkThisThrough Kuroto]] falls for the same thing. He never thought that [[BadBoss mistreating]] his partner-in-crime could derail his plans in any way. Unfortunately, said accomplice happened to be [[PsychopathicManchild Parado]], the de facto leader of [[MonsterOfTheWeek Bugsters]], [[spoiler: who proves him wrong by [[BadGuysDoTheDirtyWork killing him.]] ]]

[[spoiler: Unsurprisingly, as soon as Evolt achieves his ultimate form, he decides he has no more need for Nanba, especially since he now has shapeshifting powers for impersonations, and kills him.]]

** It's even worse in the ''Franchise/SuperSentai'' series Jungle Fury was based on, ''Series/JukenSentaiGekiranger''. Dai Shi's sorta-counterpart Rio wants to revive [[SealedEvilInACan the last of the three kenma (the counterparts to the Overlords)]], and the two he's already revived tell him that's a bad idea. Think about this, two powerful, super-evil martial arts masters are saying that reviving the last of them is a bad idea.

** In "Malleus Maleficarum" a group of housewives turn to witchcraft to better their lives. They are horrified to learn that in doing they so they made a pact with a demon and damned their souls to hell. The demon possess one [[spoiler: and murders all the others when they either make to big of a scene, annoy her, or turn on her]].
