Kinpachi is the strongest member of the Roofworlders, an organisation that resorts to living in peace on rooftops. Although physically strong and able to even contend with Earth of the The Four Elements, Kinpachi has also been trained by Kotomi-Sensei to remain quiet and sneak on his opponents, something he managed to do to Joe Musashi. At first, Kinpachi appears to be capable of not much more than basic speech, grunting at Musashi rather than talking to him directly. However, he is later seen to taunt Earth, explaining exactly how he is going to defeat him.
