Fans were thrilled to bits as Goku and Vegeta travel back to the future to help Future Trunks in "Dragon Ball Super" episode 63.

It can be recalled that Goku learned Mafuba, a technique that enables him to confine evil beings, last week. Vegeta, on the other hand, undergone a different sort of training, and they are ready to leave to go back inside the time machine to save Future Trunks.

Future Trunks has passed out and has been offered a Senzu Bean by Yajirobe. There was a whimsical moment here as Future Trunks has a sneaking suspicion that Yajirobe gave the Senzu Bean by kissing him. He tells Future Trunks that Mai was able to track down Black Goku's hideaway, Attack Of The Fanboy reported.

Mai intends to kills Black Goku without getting close to the notorious heel with the help of a special sniper rifle bullet, which according to her is very strong and should be enough to finish Black Goku. Future Trunks reminds her not to do anything immature.

While Black Goku is enjoying his tea with Future Zamasu, Mai shoots him right in the head, but much to her dismay, the bullet does not kill him. All it did was swing his earring. Realizing their plan has failed, Mai and her troopers wisely decide to retreat. It won't be surprising if Black Goku gets some revenge in the upcoming episodes.

The episode gets even more exciting once Future Trunks transforms into Super Saiyan again. This marks the beginning of some great fighting. Future Trunks uses all of his energy on Black Goku thinking that he has defeated him. He now has to face the immortal Future Zamasu and there's hardly anything he can do against him as he cannot be killed.

Meanwhile, "Dragon Ball Super" episode 64 spoilers have predicted that Zamasu and Black will try to take revenge by teaming up against Vegeta and Goku, Australia Network News reported.
