Has anyone ever really tried to be vigilante dressed like a superhero?

Question

I mean has there ever been anyone crazy enough to pretend they're batman (or any comic character for that matter) and actually go out in public and find bad guys to beat up or arrest?

Answer 1

May I know where are U from?  Why so interested in Superhero/es?

Children like superheroes to play with and adult like them to talk about.

A true tale:

A group of handicap children plus bright ones, dress-up like Superman, Wonder Woman, Batman & Robin, Ultra Man, etc and feature in an inflight magazine to pass a simple message for people to consider...........no,no,no..... not to steal or rob or kill

Think hard.....What can it be....?
