During the Resurrection F arc, Gohan beats Frieza by himself. This inspires Gohan to train with Piccolo to get stronger, as he barely beat him. Then as Gohan trains further, he becomes the strongest warrior in Universe 7 surpassing his father and Vegeta. Gohan Black is the same as Goku Black, even working with Zamasu in the same way. They have the same Zero Mortals Plan, Gohan Black’s 'Rose form' is a pink version of the Ultimate Gohan aura. It's arguably stronger than Goku Black's Rose form. The fight against Gohan Black also plays out differently. Gohan Black explains that he’s actually a Zamasu from the past. In this version, Gohan had fought Zamasu and got the god to realize how strong mortals can be. Using the Super Dragon Balls to take over his body, Gohan Black then killed Videl and Pan. This enrages Gohan, but Goku is around to keep him calm and focus on the fight at hand. Then the fight continues and Gohan Black fuses with Zamasu.
