Shortly after the tournament of power Goku and Vegeta returned with Beerus to his planet to train.
Vegeta: After falling behind you in the tournament I have to really push myself to surpass you Kakarot so I'm training with Whis and you can train with Beerus.
Goku:Ok Vegeta I won't be falling behind I want to be able to beat Jiren alone next time.
Whis: I suppose that settles that so let's begin training Vegeta.
Beerus: Goku don't think just because you mastered ultra instinct that you can beat me. I won't be going easy on you this time.
So they began their training meanwhile in space on a planet near Earth a dark evil alien begins to approach.
Meanwhile back on Earth at Kami's lookout Piccolo and Dende are watching over the Earth as they notice the power of the evil alien coming toward Earth.
Piccolo: Dende I need you to stay here I'm going down to get Gohan and the others ready to protect Earth and see if we can reach Goku and Vegeta.
