In the upcoming episode of "Dragon Ball Super," fans will see a whole new arc wherein Vegeta's hybrid son from the future, Trunks, will drop by Goku's present time.

Episode 46 will see Goten and Trunks getting trapped inside Monaka's luggage and Vegeta will have to save the two kids. The worried father will then have to enter Planet Potaufeu to get both Goten and Trunks back to Earth.

In episode 47, a grown-up Trunks will be the center of the story as spoilers reveal that he will find Goku and his team for an unrevealed reason. A user named Gojiitaf revealed the events that will occur in the chapter through Facebook.

The translated plot summary that Gojiitaf obtained from DB-Z reads: "From June 12 (Sunday) starts a new chapter original designed by Akira Toriyama: Arc Trunks Future. After the tournament against the Universe 6, Trunks returns from the future to find Goku and the others. After defeating Cell, peace would have been restored, but the reason for his coming is ...!?"

It seems Gojiitaf wasn't able to get additional information as the summary appears to be cut. On the other hand, Attack of the Fanboy further reveals that a new and evil alien race will be attacking Planet Potaufeu.

Meanwhile, a new villain by the name Black Goku will rise. According to The Bitbag, he is believed to be a merciless killer and loves to see people killed just for fun. Black Goku appears to be Goku's impostor and his entry is said to be a threat to not only Goku but his friends as well.

The grown-up Trunks has reportedly encountered Black Goku on his way to Goku's present time and Vegeta's son almost dies at the villain's hands. It is unclear if Trunks himself will get into battle with the mysterious foe but some speculate that either Vegeta or Goku will intervene to keep Trunks from getting into bigger trouble.
