Ogre, also known as Oni (鬼; Literally meaning "demon"), is a power user and a member of the Robert's Ten. His real name is unknown. Oni wears an all black outfit with horns and a forehead protector which is actually a form of chain mail. He doesn't say much, but he is able to defeat most opponents quickly. His power is to change bamboo swords into hedge clippers. He is shown defeating an unnamed opponent (Kagura in the anime) with the power to change leaves into blades, but because he defeated him so quickly, it is unknown if he used his sword or his hedge clippers. Usually seen with Becky. Ueki defeats him with Ranma.
