Prince Kravik

Kemper von Cart, aka Prince Kravik of Kravia, was the central villain of the Nightwing miniseries from 1995. He took the place of the real Prince Kravik, whom his father killed, to avoid an open rebellion by his people - only to become an even worse monster than the boy he had replaced.

Character History
Kempter's father, an aristocrat serving under Kravik's father, watched Kravik succeed to his father's throne after his parents died. He proved to be a budding tyrant, so much so that von Cart planned to quietly assassinate him and replace him with his son Kemper rather than openly rebel against Kravik, which would have resulted in a bloodbath. Therefore, he disguised himself as Bubbles the Clown and lured Kravik into a circus tent after hours, where he slit the prince's throat, killing him instantly - only to see John and Mary Grayson, the trapeze artists of the Haly Circus, watching him. Kemper, whose granduncle had surgically altered him to make him look like Kravik, then took Kravik's place on the throne of Kravia and made his father prime minister. Years later, Kemper planned to have his soldiers kill any racial minorities in Kravia in a single knight, but was opposed by his father, who was then cast into a dungeon by Kemper's guards. The American crimefighter Nightwing, who had come to Kravia after finding a threatening note from Von Cart in his parent's possession, rescued Von Cart senior and brought him back to Gothan City with him, where the old man revealed his son's true identity in a nationwide announcement made by himself. He had guessed Nightwing's other identity as Dick Grayson, but died a week later in the Gotham General Hospital, taking Nightwing's secret with him to the grave.
