Dragon Ball Super Season 2: The Moro Arc

The Moro arc takes place after Goku defeats Broly and returns from Planet Vampa. Goku uses Instant Transmission to reach Earth, where Vegeta is waiting for him. The king asks Goku where he went, but Goku gives him a vague answer. The two then head to the gravity room to train. Vegeta asks how Goku's Ultra Instinct is coming along. Goku says he hasn't been able to use it since the Lychee Tournament. Just then, Bulma interrupts them and tells them they received an urgent call from Mr. Satan. Goku asks what happened, and Bulma says a group of mysterious people showed up at Mr. Satan's house and took Buu. Vegeta looks confused. “Isn't that guy really strong?” So Goku and Vegeta decide to go check it out first. Meanwhile, at Mr. Satan's house, the group is trying to get Buu onto their spaceship. Mr. Satan pulls out a gun and starts shooting, but they stop him instantly. Just as he is about to explain himself, Goku and Vegeta appear. When the mysterious man hears Mr. Satan call them by name, he seems to recognize the famous Saiyan duo as well. Mr. Satan asks them to rescue Buu, so Goku quickly attacks the people trying to take him away. But another member of the group suddenly appears behind Goku and knocks him out with ease. Vegeta and Mr. Satan are stunned. Before the prince can react, he too is subdued and knocked to the ground. The mysterious man casually says he will need the two of them to help with what comes next, then leaves Earth.
