Tatsumaki, also known as the Tornado of Terror, is one of the most powerful heroes in One Punch Man and holds the S-Class Rank 2 position. Despite her petite, childlike appearance, she is an adult with immense psychic powers that allow her to manipulate the battlefield with overwhelming force. Her personality is fiery, arrogant, and impatient, often coming across as blunt or condescending to others, especially those she sees as weaker or less competent. However, beneath her sharp attitude, she is deeply protective of her younger sister Fubuki and takes her duties as a hero seriously, showcasing a hidden sense of responsibility and loyalty. Her combination of overwhelming power, confidence, and emotional complexity makes her one of the most striking characters in the series.
