History Main / BetrayalInsurance

Compare to KryptoniteRing, where someone personally takes precautions in case he ever goes bad himself. Compare MoralityChain, another way to ensure the barely-good guy doesn't turn bad and betray the others; in rare cases this and that trope can overlap.

* PlayedForLaughs in ''Series/CrisisOnEarthX'', when Series/Supergirl is understandably alarmed to discover that [[Series/{{Arrow}} Oliver]] carries Kryptonite arrows when he fires one at her Nazi counterpart Overgirl.

* Late in ''Manga/ZettaiKarenChildren'', [[spoiler:Minamoto]] is ordered to always carry [[spoiler:the gun with which he kills Kaoru in the precog's visions]], notably he feels pretty conflicted about it.

* An important part of ''TabletopGame/{{Shadowrun}}'' is to obtain this. Most MysteriousEmployers in-game are {{Treacherous Quest Giver}}s, and most of your allies outside the group tend to be fair-weather friends at best. Finding out who you're dealing with and making sure they'll regret double-crossing you is a common precaution.

** In ''ComicBook/JusticeLeagueOfAmericaTowerOfBabel'', it is revealed that Batman has very, very cynical methods set away in case any of the Justice League members go rogue. The plans are stolen and used against them by [[spoiler:Ra's al Ghul]]. The enemy starts by using a sort of third-party Kryptonite Ring against Batman: stealing his parents' bodies from the cemetery. This works to distract the Bat, drives him nearly mad, and leads him to abandon the JLA while searching for the culprit. After it's all said and done, the JLA (who had no idea about the plans) are ''pissed'' with Batman and [[spoiler: ultimately vote 4-3 to expel him from the League - Flash, Green Lantern, and Martian Manhunter vote in his favor because [[JerkassHasAPoint they put aside their anger and recognize that Batman has a point about the danger of a rogue JLA]], while Superman, Wonder Woman, Aquaman, and Plastic Man vote to expel him because they can't trust him anymore. However, when they go to tell him the verdict, they discover [[ScrewThisImOuttaHere Batman has already left.]] His plans are the following:

This works to distract the Bat, drives him nearly mad, and leads him to abandon the JLA while searching for the culprit. After it's all said and done, the JLA (who had no idea about the plans) are pissed with Batman and consider throwing him out of the League. His plans are the following:

*** For Wonder Woman, Batman knows that her determination in battle will never die. A device makes her hallucinate so she thinks she's facing unending waves of enemies, with no chance ever to rest. She can't interact with the rest of the world, and eventually her heart will give out.

*** For the Flash, there is an implant that gives him constant uncontrollable seizures — at light speed. After 20 minutes of seizures he thinks he's been in them for days, in such pain that he prayed just to die.

* Towards the beginning of the Franchise/DragonBall anime, Bulma slips Oolong a little something that causes him severe digestive distress any time someone shouts "piggy piggy." (or "swee swee" in the manga) This was initially to stop him betraying the group or running off, but she also happily uses it to control him in more petty ways.

* In ''Series/{{Castle}}, one episode focuses on an old friend of Castle who is a suspect in a murder, because of how he is suspected of being involved in his father’s murder. Castle believes that he’s innocent in both cases. However, at the end of the episode, while Castle is proven right that his friend was innocent in the case of the episode, he ultimately was involved in his father’s death, because the man who he hired to murder his father had kept the map of his father’s mansion that he gave him to sneak into the place and kill him.

* This specific dynamic, Franchise/{{Batman}} holding Kryptonite, appears again and again, especially in the Franchise/{{DCAU}}.

* PlayedforLaughs at the end of one episode of ''WesternAnimation/KimPossible''. AlphaBitch Bonnie signs a contract with Kim's brothers Jim and Tim so that they can fix her car. It doesn't take long for her to get fed up with their demands and throws them out of the car. The twins anticipated this and used their new gadget to wreck Bonnie's car.

*** It's even fore-shadowed in the preceding episode, Batman and Superman have a falling out over the latter's supposed obsession with killing Darkseid. By the end of the episode, Superman glares somewhat menacingly at Batman, saying "you're not always right". Cue the next episode, where Batman shows up with kryptonite.

** ''WesternAnimation/TheBatman'' has an incredibly cynical version. When Batman got a piece of kryptonite off of Metallo, not only did he keep it, he ''lied about giving it back'' (he gave Supes a fake one and kept the real one). He did it to "get even" with Superman for finding out his identity. However, by the end of the episode, it's the idealistic version, as they have settled their differences, and when Batman offers to give Supes the ''real'' kryptonite, Superman says to keep it. It still goes to show you that Batman really doesn't like anyone being nearly as CrazyPrepared as him.

*** Similarly, upon learning that Batman has a "contingency plan" to stop ''every single one of the League'' Superman tries to chastise Batman by demanding what he'd think if he found out Superman had a contingency plan to stop him. Batman's reply earns Superman's respect and friendship once more:

** Batman makes an oblique reference to having Kryptonite in reserve in ''ComicBook/JusticeLeagueTheNewFrontier'', when he warns J'onn J'onzz that he [Batman] knows ''his'' weakness [fire], too.
