Goku Black

Goku Black (Japanese: ゴクウブラック, Gokū Burakku), also known as Zamasu, is the main antagonist of the "Future Trunks Saga" in Dragon Ball Super. Originally Zamasu, an apprentice Supreme Kai from Universe 10, he swapped bodies with Son Goku using the Super Dragon Balls due to his hatred for mortals. He then appeared in Future Trunks' timeline, calling himself "Son Goku" and wreaking havoc, thus being named "Goku Black" by Bulma. Possessing Goku's fighting abilities and Saiyan physiology, Goku Black can transform into Super Saiyan Rosé. He allied with Future Zamasu to eliminate all mortals and create an ideal world ruled by gods. With his twisted sense of justice and immense power, Goku Black posed a significant threat to the protagonists. He murdered Bulma in the future timeline and, alongside Future Zamasu, nearly destroyed the entire universe. Goku Black is a compelling villain in the Dragon Ball series, and his appearance adds to the intrigue of the storyline.
