The Skull Man
Whilst stumbling about on the net I found this creepy looking guy called The Skull Man, who is the main character in a Shōnen manga series created by Shotaro Ishinomori in 1970. It caused a sensation as The Skull Man was the first of the antiheroes to be seen in manga, as the guy would sacrifice innocents in his quest for vengeance.(Wicki).
In 2007 Studio Bones adapted the Skull Man into an anime TV series which can be bought on Amazon for $28.78
