Meizu was a hot-tempered and extremely cruel person who loved to torture his victims. He was described as a bully with an uncontrollable temper. Unlike his cold-blooded brother Gozu, he easily gave in to rage and acted impulsively. It was he who rushed into battle first and did not like to wait, preferring quick and bloody reprisal. Despite his violent temper, he unquestioningly obeyed Zabuza and was devoted to their common cause. In a pair with Gozu, he played the role of the aggressor, while his brother restrained and guided him. He felt nothing towards his enemies except the desire to kill them as soon as possible. His cruelty knew no bounds, and he took pleasure in inflicting injuries. Outside of battle, he behaved arrogantly and provocatively. With all this, he remained a professional, capable of sneaking up on a target unnoticed and delivering a fatal blow.
