Karlof is the Elemental Master of Metal and a descendant of the original Elemental Master. He worked as an aeronautical engineer in Metalonia, but he found he was happier just hammering opponents with his metal fists. When he smashes his fists together, his entire body becomes metal. He also has greater than average durability. Although he comes across as brutal and rough, he shows great loyalty to his friends and was a huge help to the ninja in their battle on Chen’s island.
