Everyone shocks at the newborn warrior, especially Gowasu since he told his students about the power of Potara fusion. Shin explains to Future Trunks and Mai about the effects of the earrings as Zamazu proceeds to release his divine power. He then attacks Vegeta with an incredible speed that reverts the Prince from Blue to normal. The corrupt Kaioshin glares at Goku, who is still standing after successfully avoiding the punch. Zamasu maliciously smirks.

"Show me your true power, Saiyan!"

Goku smiles as he turns into Super Saiyan Blue, which surprises Trunks and others. As for Kaioshins, they sense something is off at the Saiyan's godly power. Goku and Zamasu are almost even until the corrupt Kaioshin forms a halo behind him. He then produces numerous attacks towards Goku and at Kaioshins to kill them. The King of Everything deflects all of them using Kamehameha, while Trunks also protects the gods. Trunks rush himself to fight Zamasu, but he breaks his sword and gives a blast that almost kills him. After kicking Trunks on the ground, the semi-Kaioshin creates sun-like energy to destroy everything. The son of the Prince barely standing and gathers all of his strength and fires Galick Ho. A few moments later, Vegeta joins his son to create a father-son Galick Ho.

"Pathetic mortals will never learn when to give up."

Zamasu increases his power to push back; however, he doesn't realize that Goku stands behind him with a Kamehameha.

"A foolish god will never learn when to give up."

Two powerful attacks strike Zamasu, and it creates a few cracks upon the sky. The Kaioshin of Universe 10 fears that the universe will be destroyed if another strong attack like this happens again.

Merged Zamasu survives, but Gowasu points out that the fusion will only last for an hour due to they have yet officially becoming Kaioshin. On the other hand, fusion can be defeated because Black is not immortal. Goku and Zamasu are face-to-face. Zamasu is first to attack, which Goku calmly dodges and delivers a heavy punch against his stomach. Zamasu is being pushed back by the Energy of Destruction in which it explodes.

"DAMN YOU SAIYAN!"

Zamasu is furious, and so he fires countless blasts. Meanwhile, Vegeta comments that Kakarotto is fighting at 100% of Super Saiyan Blue by sealing its power into his body. But doing so would create a tremendous toll, even Vegeta had some struggling to maintain in that form. Based on the fight, he can tell that Kakarotto is perfectly controlled Blue. Goku closes his eyes, raises his arm, and an invisible force is sent to Zamasu. The Kaioshin coughs some blood before returning the favor. He appears behind the Saiyan and kicks him in the sky. At the same time, he creates large energy and launches it towards Goku. Obviously, a small amount of Energy of Destruction nullifies the attack.

"There is something I need to tell you. That fusion only lasts for 1 hour."

"What did you just say?"

Zamasu is shocked to hear the news and blame Gowasu for hiding this from him.

"One more thing...I can go beyond Super Saiyan Blue."

This stuns everyone, including Vegeta. Kakarotto, what are you planning to do.
