Towa is a demon scientist from the Demon Realm and a major antagonist in the Dragon Ball Xenoverse and Dragon Ball Heroes series. As the sister of Dabura, the King of the Demon Realm, she possesses both royal status and exceptional magical abilities. Her primary goal is to resurrect the Demon Realm to its former glory by manipulating time and gathering powerful energy from fighters throughout history.

Towa uses her scientific genius to create powerful warriors and her magic to corrupt heroes into serving her dark purposes. Her partnership with the artificial demon Mira, whom she created and later develops feelings for, adds a complex dimension to her villainy. With her distinctive white hair, revealing outfit, and staff, Towa has become one of the most recognizable antagonists in Dragon Ball's expanded universe. Her cunning intelligence and willingness to manipulate the timeline make her a persistent threat to the Time Patrol.
