In episode 66 of "Dragon Ball Super" (aired November 13, 2016), entitled "The Climatic Battle! The Miraculous Power of a Relentless Warrior," super Saiyans Goku and Vegeta continue their fight against the merged Zamasu. Goku and Vegeta used Potara fusion to become Vegito and fired a final kamehameha against Zamasu.

Although the merged Zamasu sustained critical damage from Vegito's kamehameha, the Supreme Kai apprentice survived the attack. Moments later, Goku and Vegeta emerged from their fused state involuntarily. Without Vegito's Super Saiyan Blue level's power, fighting the merged Zamasu, even at a weakened state, would be difficult for the Saiyans.

Realizing that he has an opportunity to finish the Saiyans off, merged Zamasu attacks Goku and Vegeta only to be warded off by Trunks. With Trunks "borrowing" and then channeling everyone's ki to his sword, he attacks and successfully cut Zamasu in half.

In a report from iTech Post, Episode 67 of "Dragon Ball Super" will have the title "Fill Your Heart with New Hope!! Farewell, Trunks" and will air on November 20, 2016. Trunks go for an all-out attack, using every ounce of his power, to destroy merged Zamasu.

Trunks successfully defeat merged Zamasu only to find out that radiant god is not completely destroyed. Lacking a body, merged Zamasu has become more powerful. Zamasu threatens everyone's existence as he spreads out and covers the sky seemingly preparing to annihilate everyone.

With everyone's survival hanging in the balance, Goku fishes something out of his pocket. No one knows what Goku has under his pocket but several "Dragon Ball Super" followers are of the opinion that it is likely to be the button that the Omni King Zeno has given him.

Goku can summon Zeno at any moment by just pushing the button. And with the Omni King being that most power being in the universe, Zeno seems like the only one who can stop Zamasu.
