Scene from Episode 38 of Super Dragon Ball Heroes where all the non-canon scenarios take place. Characters from different series, arcs, and timelines converge together and fight each other.
In this particular scene, Goku Black has grown in power and was able to surpass his level and turn into Super Saiyan 3 Rose. Thinking that this form would be enough, Gogeta continues to show just how OP he is. As soon as both Goku and Vegeta fuse, Gogeta is already powered up in the blue form.
Because Gogeta utilizes both Goku and Vegeta’s power and skillset, during the fight he uses the Mastered Ultra Instinct Ability and tops it off with Emotion Control. Goku Black doesn’t stand a chance against this awesome power. But who can?
