Hammerhead Hannigan

Hammerhead Hannigan is the right-hand goat henchman of Taurus Bulba and one of Darkwing Duck's first enemies, appearing in the pilot episodes "Darkly Dawns the Duck". He and his two bumbling subordinates, Hoof and Mouth, carried out Bulba's orders while he was in prison, but were often incompetent in doing so. Hammerhead personally went to kidnap Gosalyn from the Orphanage, claiming to be an old friend, but was stopped by Darkwing Duck.

He used his long horns to charge at opponents but could also use them to pry open doors and latches like the other side of a hammer's head.

Hammerhead later appeared in the episode "In Like Blunt", where he went to a black-market auction run by Phineas Sharp.
