By nature, Zaraki is an aggressive and violent man who lives for the rush and carnage of battle, enjoys a good fight more than anything. He even makes a point to hold back against foes weaker than him just to make the fight last longer. He claims injury and death are nothing but the price one pays for a good fight. Despite this savage nature, he is not without a sense of duty, able to accept orders from his superiors. As such, his actions tend to be in Soul Society's best interests. Likewise, he has his own principles. He insists on a one-on-one fight regardless of the foe. Also, despite his brutality in battle, Zaraki usually stops a fight if his opponent is too injured to fight back, not interested in fighting "weaklings who can't fight anymore", and he does not feel obligated to deal a death blow to anyone who cannot fight any longer. However, he will unhesitatingly kill his opponent if they refuse to stop fighting, such as during his battles with Kaname Tōsen and Nnoitra Gilga.[7][
Speaks in short, hard bursts; growls out challenges; rarely over-explains; throws in direct orders and blunt taunts.
