'Dragon Ball Super' Episode 46 spoilers rumors update: Goku fights Copy Vegeta; New major story arc coming up?
Akira Toriyama's "Dragon Ball Super" is currently centered on the events at Planet Potaufeu where Trunks, Goten and baby Pan found themselves trapped in. The upcoming Episode 46 of the highly popular anime series will follow the story of the mysterious planet's magical power source called the "Superhuman Water," and it will also feature the impending battle between Son Goku and Copy Vegeta, which was spawned by the Superhuman Water's mysterious effects.

The latest preview trailer for "Dragon Ball Super" Episode 46 shows Son Goku following Goten and Trunks in Planet Potaufeu after the two were accidentally transported by Monaka's spaceship. Unbeknownst to them, the planet is a refuge to a mysterious Superhuman Water, which has the ability to shapeshift into another person and copy its strength and power after it absorbs him. To recap, Vegeta was the first one to follow the children in Planet Potaufeu, but he was encountered by the villainous Potaufeu resident. As a consequence, the evil and powerful Copy Vegeta was spawned, causing more trouble for Trunks and Goten.
To recap Episode 45, Goten and Trunks decided to fight Vegeta's slimy impostor, although it was not an easy thing to do as the Superhuman Water villain possesses the same skill and power level as Vegeta. In an effort to defeat Copy Vegeta, Goten and Trunks used the famous Fusion technique to become the Super Saiyan 3 Gotenks. However, it appeared that Super Saiyan 3 Gotenks is still no match to Vegeta's impostor. The ending sequence of Episode 45 was a cliffhanger, and the next episode is expected to pick up right after Gotenks and Copy Vegeta's fight. Goku will also try to take down Copy Vegeta, and the viewers will see if Goku's current power is enough to take down an entity as strong as the original Saiyan Prince.
On the other hand, it has been reported that "Dragon Ball Super" may be heading to another major story arc after Universe 6 versus Universe 7 tournament. Episode 47 is rumored to feature the return of Future Trunks, who will bring the bad news from the future. It is reported that Black Goku will be the next big villain of the series, and his power can match that of the universe's gods of destruction and even the Supreme King himself.
