Phineas Sharp

Phineas Sharp is a one shot character that appeared episode 150 "In Like Blunt." He was voiced by the late Jonathan Harris.

Darkwing Duck
Arch-enemy of Derek Blunt, Phineas Sharp was an evil, twisted vulture (literally) who wanted revenge on both Blunt and S.H.U.S.H. for an earlier humiliating defeat. He stole the master list of S.H.U.S.H. agents, so that he could lure Blunt to his island resort in the Salad Sea, hoping to make the elder agent's erstwhile retirement "permanent."

Having the list of SHUSH agents, Phineas planed on auctioning off the the list to highest bidder and corner the China tea market. To do this Phineas invited villains to his island resort. His scheme was foiled by Darkwing Duck and Blunt, who switched the real list with a grocery list taken off of Horatio. To the end of this scene, Phineas Sharp was last seen being threatened with a pounding by Hammerhead Hannigan, the buyer of the agents list.
