Goku Black

Goku Black is the result of Zamasu from the present timeline using the Super Dragon Balls to steal Goku's body. Wielding Goku's Saiyan physiology alongside his own divine ki as a Kai, he achieved power levels far beyond what the original Goku had at the time. He aligned with Future Zamasu to execute the Zero Mortal Plan across the alternate future timeline, becoming one of the most personal and chilling villains the Z Fighters have faced — an enemy who literally wears the face of their greatest hero.
