The moment their arms spun freely in our air, they were doomed — for Man has earned his right to hold this planet against all comers, by virtue of occasionally producing someone totally batshit insane.
This is when the clinically insane person turns out to be
The Only One who has the right stuff to stop the Omnicidal Aliens,
Cosmic Horror or
Big Bad. It could be his bent perceptions allow him to see things "normal" people can't. Or maybe the bad thing that happened was so completely
out of the realm of possibility that
only the total nut job prepared for it. Keep in mind, what separates this from
Sociopathic Hero or other crazies is that this character's madness is
essential to the task. If he was not crazy, he could not do it.
This guy put the Crazy in front of
Prepared and
Awesome, but don't confuse him with an
Ignored Expert or
The Worm Guy, who are not actually insane, just misunderstood. Not to be mistaken for his padded-cellmate the
Sociopathic Hero, who is a hero
in spite of his anti-social tendencies, not because of them.
When the whole human race is composed of Heroic Madmen, it's
Humanity Is Insane. Compare
The Cuckoolander Was Right and
Power Born of Madness, although this trope doesn't necessarily involve superpowers. See also
Blessed with Suck.
Examples
Anime
Comics
- Crazyman from Continuity Comics, whose power is being crazy. "Crazyman" is recruited by a secret service as the "Plan B" to dangerous "unwinnable" situations. Danny is to the secret service as Monk is to the San Francisco Police Department, and comes up with solutions no sane man would come up with. If James Bond were insane, he'd be Crazyman.
Film
Literature
- Redwall - In High Rhulain, The hare Major Cuthbert went insane after his daughter was killed by vermin. He ended up killing a sea monster single handedly.
- In Larry Niven's Madness Has Its Place, Jack Strather's megalomania and paranoid schizophrenia make him one of the few men left on Earth with the cojones to actually resist the invading Kzinti.
- Blindsight: The main character's severe autism means he's the only one able to objectively synthesize all of the information and determine just what the deal is with the Starfish Aliens they discover. Of course he's also unable to bond with other people or empathize with them, so...downer.
- In C.S. Friedman's This Alien Shore, the Guerans (a mutant race descended from humanity) are all insane, which makes them the only ones who can pilot ships through hyperspace. In addition, the heroine's multiple personality disorder grants her a secret power that could alter the balance of power throughout known space.
- Jack Vance: One of his short stories (The Men Return to be exact) featured a world where causality had basically gone out the window. One character was barely surviving, trying to find patterns where there were none. The ones who were crazy before The Event on the other hand were basically gods.
Live Action Tv
- Seven Days: the only person able to pilot the Chronosphere is Frank Parker, inmate at a military insane asylum.

- Portal: Schizophrenic Doug Rattman was completely right in suspecting the operating system was out to kill everyone and so was the only survivor of the lab incident.
