The masturbating gunman makes his appearance in the Masked Avenger Versus Ultra-Villain in the Lair of the Naked Bikini.

A gunman gets on the trail of kidnapped women he gets hired to locate by sniffing the crotches of their soiled underwear. The plot involves the gunman’s search for a nun, his sister.  In one bravura sequence, the trapped gunman, inspired by his sister’s panties, kills his enemies by firing large loads of his own acidic semen at them. Similar structurally to ‘Rapeman’ in that the gunman and his hunchbacked servant operate out of a legitimate office and offer their ‘find-a-girl’ services as if they were offering carpet cleaning.”
