THE FOLLOWING IS A FANFICTION STORY. DRAGONBALL FIGHTERZ IS MADE BY ARC SYSTEM WORKS AND BANDAI NAMCO.

Battle 04-Android 21 vs Frieza Goku (Super Saiyan) and Vegeta (Super Saiyan)

After the defeat of the Evil Android 21 and the sacrifice of the Good Android 21, The Universe was once again at peace. However 21 days later, Goku and the other Z Fighters, the villains too suddenly find themselves teleported to a "duplicate" Earth, and that's not all.

Specifically all who are playable in DragonBall FighterZ have been pulled from their worlds/timelines and into this duplicate one, including 3 different Goku's (One from the Saiyan Saga, One who can only go Super Saiyan 1-3, and One that can go only Super Saiyan Blue) 2 Gohan's (One from the Cell Saga and the Adult Gohan) Kid Buu, Frieza, The Ginyu Force, Nappa, Bardock, Cell, Broly, Cooler have all been revived, 3 different Vegeta's (In the same situation as the 3 Goku's, Hit from Universe 6, Goku Black and The Fusion Form of Zamasu, The Fusions Vegito and Gotenks, Future Trunks, even Beerus too, all the playables of DragonBall FighterZ have been brought here to this identical duplicate world.

As everyone was wondering what was going on and who's responsible, mostly getting into a huge battle with each other, The Evil Android 21 revealed herself alive once again and the one responsible for kidnapping the fighters. She tells them that she created "duplicate worlds" (based on the stages on the game) where she is the absolute ruler and in control. She brought them all here so she could continue her hunting game but on a bigger scale and for her to be in control and win this time. Evil 21 also reveals that her revival, the fighters brought to the duplicate worlds for her to control, was also done by her new and permanent link partner...Me.
