"Dragon Ball Super" episode 46 follows the story of the magical power source of the mysterious Planet Potaufeu known as the "Superhuman Water" and will feature the faceoff between Son Goku and Copy Vegeta, which was cooked up by the Superhuman Water.

In the preview trailer for the upcoming episode, Son Goku follows Goten and Trunks in Planet Potaufeu after they were inadvertently conveyed by the spaceship of Monaka. Both seem to have no idea that the planet is actually home to the uncanny Superhuman Water, which has the ability to absorb a person and create a duplicate of him that possesses not just his exact physical features but his strength and power as well.

In the previous episode, Vegeta was the first one to go after the children in Planet Potaufeu, where he stumbled upon the atrocious Potaufeu resident. This encounter led to the creation of Copy Vegeta, posing direr straits for Goten and Trunks.

The fight between Goku and Copy Vegeta will be witnessed by Trunks and Vegeta. Spoilers for the episode suggest that the real Vegeta will arrive to witness the bout, but he will not join forces with Goku in fighting his evil duplicate.

In other news, talks have been going around that "Dragon Ball Super" will head to another story arc following the tournament between Universe 6 and 7. Rumors have it that episode 47 will see the return of Future Trunks and that Black Goku will be the next super villain to watch out for.

"Dragon Ball Super" episode 46 will air on June 5 on Fuji TV.
