Ultimate ninja

The Ultimate Ninja is the son of the Ultimate Daimyo, the master of the Battle Nexus which is a tournament from the greatest warrior every three years to see who is the champion of the multiverse. The Ultimate Ninja makes his first appearance in "Ultimate Ninja." He came to Earth to challenge the Shredder but learned that the Shredder met his apparent demise by Leonardo. So he challenged Leo to a duel and they fought to the death. However, the Ultimate Ninja fought with no honor and tried to kill Leo after the duel was finished.

However, despite this, he has a caring side for his father to the point of banishing him to an unknown island instead of killing him. By the time he and Drago are separate beings once again, he begs his father to forgive him before being turned into stone. Luckily, he is revived as a child with no memories of his actions.
