'''Basic Trope''': Being insane has various metanormal benefits.
* '''Straight''': Jack has a looser grasp on reality than most. This lets him carry out plans that shouldn't succeed and spot weaknesses that don't occur to others.
* '''Exaggerated''': Purely by virtue of being insane, Jack is a RealityWarper.
* '''Downplayed''': Jack doesn't seem to live in the same reality as the others, but it is a coherent reality, he tends to be the first to figure out a new idea.
** There's an unstable energy source that insane people are more able to tap and control.
** Alternatively, the power works by [[RealityWarper making the user's personal version of reality override the consensus version]]--only the insane and the [[AchievementsInIgnorance ignorant]] can actually ''use'' it, because you have to outright believe your own version is possible in order for it to work, and normal people know it isn't.
** Jack is a superhero, and loses his powers when he goes insane.
** Jack is hyper sane which allows for amazing feats such as being unfazed by even an EldritchAbomination and having impeccably clear judgment.
** WithGreatPowerComesGreatInsanity, a madness born of power.
* '''Subverted''': Jack isn't clinically insane, he's just smart enough to look that way to most people.
* '''Double Subverted''': There's a thin line between genius and madness, and Jack crosses it a few installments into the story.
* '''Parodied''': Adventurers looking to fill party niches always begin by searching insane asylums.
* '''Zig Zagged''': DependingOnTheAuthor, Jack is insane and skilled, insane and useless, brilliant and eccentric, or just unusually snarky.
* '''Averted''': No insane people have special abilities, and no one with abilities beyond the norm are noticeably insane. CrazyAwesome, maybe, but not insane.
* '''Enforced''': The story is an AuthorTract about equal opportunity badassitude for people diagnosed with mental disorders.
* '''Lampshaded''': "Yeah. Figures the nutjob saves our bacon."
* '''Invoked''': Bob tries to drive Jack crazier in order to increase his power level.
* '''Exploited''': The BigBad of the setting simply executes any obviously insane heroes he captures- because while a sane man will accept that he's been captured and can't escape, a madman will somehow find a way to escape a literally inescapable prison.
** Someone who starts getting a power-inducing mental illness seeks out treatment.
** Preserving the powers while minimizing/eliminating the undesirable parts of the insanity is the goal of the treatment.
* '''Discussed''': "Seriously? The pyromaniac developed pyrokinesis? Why do only the crazy people get the superpowers?"
* '''Conversed''': "You know, the world would be so much more dangerous if insanity came with supernatural powers..."
* '''Deconstructed''': Jack's insanity is getting worse, and as it does, his power increases. Cue FaceHeelTurn, AGodAmI, or any number of things that can go wrong with immense power with an unstable mind behind it. His teammates are forced to terminate him before he threatens the rest of reality.
* '''Reconstructed''': Jack's power, and with it his insanity, can be switched on and off. He may be dangerous while 'in the zone', but can at least be aimed in the right direction.
