Hammerhead Hannigan

Hammerhead Hannigan is the secondary antagonist in the pilot episode ''Darkly Dawns the Duck. ''He is a goat  who is Bulba's lead henchman. He was voiced by Laurie Faso  in "Darkly Dawns the Duck,"  Tad Stones  in "In Like Blunt".

Hammerhead is a surly goat wearing a pinstriped suit who talks and acts like a stereotypical 1930s gangster. His gimmick is that he uses his head as a blunt object to headbutt his enemies.

He appears to be based on the Marvel Comics   villain of the same name, although a  Three Stooges  reference suggests he may also have been inspired by  Shemp Howard 's character named Hammerhead in  The Invisible Woman . His choice of attack, headbutting, may also be based on actual male goat behavior as a show of aggression & dominance. Of Taurus' henchmen, Hammerhead is the only one who went on to appear in a third episode.

He was shown briefly in the episode "In Like Blunt" about to beat up Phineas Sharp when the list that Phineas was going to sell was replaced with a grocery list
