'Dragon Ball Super' episode 64 spoilers: Goku and Vegeta to fuse too?

It appears that fans will have to expect the unexpected in "Dragon Ball Super" episode 64 titled "Bow down! Worship Him! The explosive fusion Zamasu!" as the fight between the heroes and the evil tandem of Goku Black and Zamasu continues.

Weekly Shonen Jump has provided details about this episode and with the DB-Z.com, it is learned that the stakes just got higher with Future Trunks badly injured. The synopsis is as follows:

"The clash continues between Goku and Vegeta and Zamasu and Goku Black! Vegeta leads a fierce battle to protect Trunks whose injuries have given him strength and anger. But the fight takes an unexpected turn..."

That "unexpected turn" might be in the form of a fusion between Zamasu and Goku Black as see in the "Dragon Ball Super" episode 64 promo.

Goku also displays his newfound confidence in the clip saying, "Black! Zamasu! You may be strong and immortal, but it looks like you're running out of steam."

"From here on out, it's time for our payback. Zamasu, I'm going to seal you away. Don't underestimate the strength of mortals!" the Saiyan declared, showing a renewed spirit going into "Dragon Ball Super" episode 64.

However, the battle is just about to get more intense as Zamasu and Goku Black fuse together to form an even stronger adversary for the heroes.

With the powerful villains rolled into one, Goku and Vegeta are in serious trouble. However, rumor has it that Goku and Vegeta will also fuse together in "Dragon Ball Super" episode 64 to become Super Saiyan Blue Vegito.

Gowasu and the Supreme Kai are expected to help them make that possible in "Dragon Ball Super" episode 64. Beating Zamasu and Goku Black is no longer an option.

But if the heroes want to seal the enemies in the Mafuba jar using the Evil Containment Wave technique, they will have to be extra strong to pull that off.

This is only mere speculation, but with Zamasu and Goku Black now even more unstoppable, Goku and company will likely resort to desperate measures.

Dragon Ball Super" episode 64 "Bow down! Worship Him! The explosive fusion Zamasu!" will air Sunday, Oct. 30 on Fuji TV.
