After Zamasu managed to escape Future Trunks' attempt to seal him in a jar using the failed Mafuba technique in the previous episode, Fusion Zamasu can start issuing a "Wall of Light" in episode 65 of "Dragon Ball Super."

Spoilers for the upcoming episode titled "Final Judgement?! The Supreme God's Ultimate Power!" revealed that the result of Future Zamasu and Black Goku's fusion will face Goku, Vegeta, and Future Trunks in an intense battle.

In the previous episode, Future Trunks tried to imprison Zamasu permanently inside a jar using the Mafuba technique that he learned by simply watching how Piccolo did it in a step-by-step video. However, Gowasu's former apprentice managed to escape Future Trunks' efforts after the latter forgot to bring the magic paper needed to lock the jar completely. This means that Zamasu and Black Goku will continue with their evil plans to wipe out all the mortal beings in the entire universe by merging themselves.

For the upcoming episode of "Dragon Ball Super," the powers of the villains will intensify with the help of the potara earrings. The fusion between the two evil villains will allow the new supervillain to possess the power called "Wall of Light."

Attack of the Fanboy revealed the synopsis for the upcoming episode, which reads: "Goku Black and Zamasu merged with Potaras!! An immortal body combined with a high-powered combat capability make it a formidable enemy!! But above all, Merged Zamasu can issue a 'Wall of Light' which removes everything he touches. To protect the inhabitants of the West Capital Zamasu, Trunks is firmly determined to face Zamasu! Having received by 2 Senzu Beans from Mai, it sinks towards Zamasu."

This means that Future Trunks will have no choice but to use whatever power he has left in order to defeat the superpowers of the new villain.

Episode 65 of "Dragon Ball Super" is scheduled to be released on Sunday, Nov. 6, on Fuji TV.
