Tatsumaki has a rather brash, moody, hotheaded and impatient personality. She is disrespectful towards most people, especially to those she deems incompetent. She is completely intolerant to those who are impertinent, as shown when she pinned Genos to a large rubble for retaliating against her verbal abuse of Saitama. But she has a soft and a little love side for people who make her laugh.
