One of Third Earth's most formidable warriors, and one of the ThunderCats' most powerful allies, Hachiman lives his life by the code of Bushido, a strict code of honour that shapes his every action. As such, Hachiman is both quick to anger at a display of injustice and slightly arrogant and superior in his bearing, two personality traits that, taken together, have allowed Hachiman to be duped into taking action against his friends, the ThunderCats. Despite this, the tenets of Hachiman's code of honour also make him an extremely loyal ally to those who serve the Code of Thundera, namely the ThunderCats and their friends.
