Hollow Ichigo's most distinguishing features are his maniacal laughter and psychotic grins. He is brutal, arrogant, disrespectful, and sadistic. His only reason for existence is to take over Ichigo's power and body to use it to kill everything and anything he sees. He taunts Ichigo as being a weak and unsuitable counterpart of himself.. He battles like a berserker, unlike Ichigo, ignoring injuries and overpowering his enemies with brute strength and force. He also protects Ichigo's body when he is about to die, because if Ichigo died, he would too.
