Geberuk is an old servant in the Pharaoh's palace who receives an order form Seto to prepare an army of monsters. He is maybe the first who discovers that every KA becomes stronger when wins in a fight against other KA. Geberuk opens in the palace a hall in which he forces the captured criminals to confront their KAs against each other.
In the future, Geberuk can be recognized as Hobson - a servant in Gozaburo Kaiba's old house.
