Baka Ki El Dogra

The first prince of the planet Dogura. He has an exceptionally high IQ and has little interest other than using it to torment those around him for his own amusement. His real name is Baka Ki El Dogra, but everybody refers to him solely as Prince or Prince Baka (a play with words since baka-ouji can mean both "Prince Baka" and "stupid prince"). He also appears for a few minutes in episode 36 of Hunter x Hunter (2011), commenting on an arena match. His voice actor was unlisted, however.
