Mr. A (Comic Book) – TV Tropes
http://tvtropes.org/pmwiki/pmwiki.php/ComicBook/MrA
Born in 1967 of Steve Ditko’s fascination with Objectivism, Mr. A is a “superhero” without observable powers aside from his steel gloves and mask, similar to the first incarnations of The Question.
Philosophical elements aside, Mr. A marked Ditko’s shift from working on contract for mainstream publishers like Marvel and DC to more creator-owned projects; Mr. A was first published in the Underground Comics series witzend and was later collected in self-published comics Ditko distributed himself.
Alan Moore disliked this character strongly and portrayed this type of character in a rather twisted way as Watchmen’s Rorschach.
