Super Dragon Ball Heroes EP16 - Zamasu vs. Universe 7! Ambition's End!

Vegeta and the others try to attack Hearts while he is absorbing the Universe Seed, but Zamasu stands in their way as he reveals that he is only aiding Hearts so he can resume his scheme to exterminate all mortal life without the Zenos' interference. Zamasu overpowers Goku after quickly incapacitating the others, before Jiren and Hit arrive to join the fight, having been sent by their universes' Supreme Kais to deal with Hearts and his allies. Goku, Jiren, and Hit are about to attack Zamasu again when Hearts suddenly emerges from his enormous gravity cube, having assimilated the Universe Seed and its power into his body, and gaining a new form in the process. Hearts uses his new power to easily immobilize Zamasu, then traps him in another gravity cube and obliterates him completely after revealing that his goal is to destroy all the gods. The Grand Minister is disturbed after sensing Zamasu's death and Hearts' immense power, as Hearts proclaims himself to be "the Ultimate Godslayer.
