Caesar

Caesar is a new member of Genesis who was just introduce in chapter 188 to come retrieve Orca who had encountered Agito Wanijima while he was training to prefect his fang. As Caesar questioned Orca for seeking out Agito, he found himself threatened by the annoyed Agito. Caesar, however, managed to quickly cower Agito by unleashing his signature trick, Legionarius Phalanx, a move that uses blindingly fast kicks to send out numerous powerful blasts. Caesar is descended from Roman nobility and is very confident in his abilities. As a result, he appears very foppish and is very arrogant. Moments after 'defeating' Agito, he faces him again, only this time a 'fully awakened' Agito dodges his attacks and uses a double fang to slice open Caesar's scalp and much to his horror, showering him with his own blood. It has been stated by Caesar himself that he is a sadist, he seems to be characterized by a legion of bayonet using soldiers. Caesar's country seems to have advanced technology, as after he is injured by Agito, he uses a mechanical exoskeleton that he says originates from it for a short time before Orca disables him, saying he's "played around for long enough".
