Phineas Sharp is a criminal genius whom few can bring to justice. In fact, for the longest time only Derek Blunt was thought to be up to the task. Sharp and Blunt have had many encounters over the years, some seeing Sharp as the victor, some Blunt, but both always managed to survive. Eventually, Sharp was humiliatingly defeated due to his allergy for gurbstickulous sap and was locked away for a good while. When finally he escaped, revenge was strongly on his mind.
Having the master list of SHUSH agents, Phineas planned 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.
He is voiced by Jonathan Harris.
