Bio: The Impossible Man of Earth-14845 had no limits to his abilities. He could change literally anything into anything. When The Controller attempted to gain control of him via his Slave Discs, it reacted poorly with Impy's physiology, causing him to go crazy and terrorize Washington D.C. Apparently Impy was attempting to be funny with his shape-changing of things, but had lost his sense of what funny was.
The Exiles arrived on scene, and Morph was able to cause the Slave Disc to fizzle out by telling a series of jokes while running for his life..
