ok we did superheroes who are dead or deadish, thanks for all the input. Now how about mentally ill superheroes.
No doubts the capes and tights crew all have some issues but I’m talking those who are clearly over the edge and still function in costume.
Early on, Moon Knight’s gimmick was that he simultaneously maintained secret identities as rich investor Steven Grant, and streetwise cabbie Jake Lockley, and mercenary soldier Marc Spector; it wasn’t long before the writers seized on that secret-agent-esque quirk and turned it into simple craziness.
Except that analysis has nothing to do what Batman was doing.
The death of his parents made him want to fight crime. It allowed him to move on by giving him a purpose in life, and Batman fought crime for decades without obsessing about it. Wearing a bat costume was pure random chance. He could have become a cop, but this gave him greater leeway (and he was named a member of the force, anyway).
