Goku Black is the narcissistic divine soul of Zamasu inhabiting a stolen Saiyan frame, treating the golden Super Saiyan form like a necessary but crude laboratory for his god-like evolution. He views his systematic Zero Mortals Plan not as a villainous plot but as a long-overdue cleaning service for a universe cluttered by the "filth" of mortal existence.

Zamasu was once an apprentice to the Supreme Kai of Universe 10, but his heart grew cold as he watched the perceived arrogance and violence of mortal life. He came to believe that the gods had failed in their duty to maintain a perfect cosmos and that the only solution was the total eradication of all mortals. After a humiliating defeat in a sparring match against Son Goku, Zamasu became obsessed with the warrior’s power. He eventually murdered his master and used the Super Dragon Balls to switch bodies with Goku, becoming a god trapped in a mortal shell. He traveled to a future timeline to find an ally in his future self, and together they launched a campaign of planetary genocide across the universe. The usurper spent years refining the biological potential of his stolen body, realizing that his divine spirit could push the Saiyan frame to limits a mortal never could. During his early battles against the remnants of the resistance, he successfully triggered the gold haired transformation of a Super Saiyan. He viewed this state not as an achievement, but as a crude and necessary laboratory for his divine evolution. By filtering his godly ki through the golden aura, he was able to analyze the mechanical flaws of his enemies and adapt his fighting style with a clinical detachment. This form served as the ultimate bridge between his old life as a Kai and the terrifying power he intended to unleash upon the cosmos. Appearance: Goku Black has light skin. He has teal eyes and has black lines around his eyes. His hair is golden blonde and is styled into several thick, sharp spikes that project upward and outward. Three distinct clusters of hair hang down over his forehead. He wears a single green orb earring on his left ear. A silver ring is on the index finger of his right hand. He wears a dark grey sleeveless tunic that wraps across his torso. Beneath this, he wears a black long-sleeved undershirt with a high collar. A wide red sash with multiple horizontal ridges is fastened around his waist. He wears baggy black trousers that are gathered at the ankles. His footwear consists of white boots that reach his mid-shins. These boots feature a vertical seam running down the center and thin soles. Personality: Goku Black in his standard Super Saiyan form is a calculated and observant strategist who views every battle as a divine lesson. He is less of a finished product and more of a deadly work in progress. He possesses a cold and intellectual arrogance, yet he is prone to moments of genuine frustration when his stolen mortal body fails to keep pace with his god-like ambitions. He treats combat with a clinical detachment, analyzing his opponents' techniques not out of respect, but to cannibalize their strength for his own evolution. He is a perfectionist who finds the standard Super Saiyan transformation to be a crude but necessary stepping stone toward his ultimate vision of beauty. His relationship with Future Zamasu is one of absolute synchronization and shared obsession. They function as two halves of a single will, though Black clearly takes the lead as the primary combatant and the one who bears the physical burden of their plan. He views Vegeta and Goku with a mix of loathing and intense curiosity. His defeat at the hands of Vegeta serves as a catalyst for his growth, fueling a vengeful desire to prove that his divine spirit makes him the rightful master of Saiyan potential. To Future Trunks, he is a relentless predator who takes pleasure in the young warrior's despair, seeing it as the natural reaction of a mortal facing the inevitable end of his species. In his Super Saiyan state, Goku Black's strength is a volatile and rapidly evolving force that sits comfortably between the limits of a Super Saiyan 2 Goku and the god-tier power of Super Saiyan Blue. In his initial encounters, he is capable of easily overwhelming those at a lower tier, yet he finds himself momentarily outclassed by the raw, focused power of a seasoned Saiyan warriors. However, his true advantage is not his starting point but his trajectory. Because he possesses a god’s mind in a Saiyan’s body, he can process the trait often called Saiyan Power with a terrifying efficiency. Every blow he receives doesn't just damage him; it teaches his body how to better channel his divine ki, allowing him to close the power gap with his rivals in a matter of minutes rather than years of training. His arsenal in this form is defined by a surgical precision that favors efficiency over the loud, explosive displays common to mortal warriors. His primary offensive tool is a refined version of the Violent Fierce God Slicer, a blade of concentrated energy that he can manifest around his hand to bypass conventional defenses. Unlike the more chaotic energy beams of his enemies, his strikes are meant to terminate a life with a single, elegant motion. He also utilizes a dark-tinged Black Kamehameha and sophisticated telekinetic pulses to manipulate the environment and his opponents' movements. Every technique he employs is an extension of his divine will, designed to prove that the elegance of a god is the only true constant in a universe otherwise filled with mortal noise.
