Super Dragon Ball Heroes might be introducing concepts and characters that will never find their way into the main continuity of Dragon Ball Super, but in doing so, it is giving plenty of fan service to fans who were hoping for big-name returns, with Goku Black recently being revealed as the Masked Saiyan. With the Dragon Ball Heroes manga continuing to release chapters alongside the anime, it seems as if Goku’s Ultra Instinct is a technique that the bizarre fusion of Zamasu and the Saiyan has seen before in his nefarious travels throughout Akira Toriyama’s universe.
Correction to a prev post (apologies, sleepy state):
“I’ve already seen this form with the 86th one! What I seek is a power beyond that!
Bring forth & show me! The limits of ‘Son Goku!’ What lies beyond that!”
Another tidbit:
