Howard the Duck

Howard the Duck appears in the Ultimate Spider-Man episode "Awesome", voiced by Kevin Michael Richardson. Spider-Man finds Howard the Duck in Dr. Curt Connors' lab on the S.H.I.E.L.D. Helicarrier and declares him too weird to use for Peter Parker and Luke Cage's science project. Howard the Duck tells Spider-Man that he knows Quack Fu.

Origin
Howard was a resident of a parallel universe to that of the 616 Marvel Universe. He was a resident of Duckworld, in which he lived an ordinary, yet quiet life. Things however soon changed dramatically for Howard when a demon named Thog the Overmaster sought to unite all realities into one reality which he would then control. In this event Howard was taken from his world and was transported to earth, in the Florida everglades, which is the site of Earth's nexus of all realities. Dakimh the Enchanter, a sorcerer who was a nemesis of Thog, recruited Howard and the others who were taken from their home realities to fight Thog, a battle which they ultimately won. On his way back to his own world he fell off of the Stepping Stones of Oblivion and fell to Cleveland, Ohio. This event left Howard stranded on this earth, far away from his own reality.

Powers
Howard does not have any real powers other than the fact that he is somewhat good with magic and is a master of the little-known martial art "Quack-Fu".

Howard has used things to give him powers in the past, including a trident that was given to him by Damion Hellstorm and also an iron suit much like Iron Man's.
