Zangetsu's most distinguishing features are his maniacal laughter and psychotic grins. He is brutal, arrogant, disrespectful, and sadistic. Though he taunts Ichigo as being a weak and unsuitable counterpart of himself, he relishes the idea of Ichigo growing stronger as he also grows stronger as a result. Unlike Ichigo, he battles like a berserker, ignoring injuries and overpowering his enemies with brute strength and force. He protects Ichigo's body when he is about to die because if Ichigo dies, he will as well. He seems to respect the manifestation of Ichigo's Quincy powers to a certain extent. Due to his status as a Zanpakutō spirit, Zangetsu doesn't get much opportunity to fight and gets really excited on the rare occasions he does get to fight.
