Here's the full story of Universe Mission 5: It starts off with SSG Goku and Golden Cooler battling SSJ Cumber. The duo are in a pinch until Xeno Goku & Xeno Vegeta show up. They just came back from destroying Fu's lab. The SS4's fight SS Cumber evenly. Cumber then ramps it up to SS3, in which they fuse to become SS4 Xeno Vegetto. Vegetto pushes Cumber back, their battle melts the chains that hold the prison planet in the process. Fu's pissed that his lab has been destroyed and does battle. Afterwards reveals his plan to use the collected energy from the prison planet to create a big bang and thus another universe. Trunks wonders what would happen to their universe if that happened, Fu doesn't really know either. Cumber comes back, Fu commences "Plan B" and escapes the planet with Cooler chasing after him. Goku wakes up and becomes Ultra Instinct. They do battle and UI Goku seems to win. Xeno Goku teleports everyone except UI Goku outta the planet... somehow. Goku senses Mecha Zamasu is around. "SON GOKU!" Suddenly Zamasu attacks Goku. And of course while all of this was happening Majin Ozotto was able to steal the dragonballs and wish himself outta the planet too.
