You need to be playing as Future Trunks to begin this substory, plus you need to have finished Lone Guardian. You can find this inside of Capsule Corporation, but make sure Goku, Vegeta, Krillin and Yamcha are not in your party. Bulma was supposed to visit Kame House to catch up with everyone and share stories, but something else came up and she wants you to go in her stead. You will automatically go to Kame House, where everyone shares some stories about the past and Trunks learns about his father and his past. Once they part ways, head back to Capsule Corporation.

Vegeta has a few melee Super Attacks in this fight (left), Later on, try not to be too close in fear of a retaliatory Galick Gun (right)

Speak to Bulma and tell her about what happened, then Vegeta will stop by and say that you’re going to train with him. Overall, Vegeta is a pretty simple fight, as you should know all of his moves by now. He’ll mainly use melee moves (Body Smash, Mach Slash and Meteor Hammer) and Consecutive Energy Blast in the beginning portions of the session. Once you get his health lower, though, he will switch over to Galick Gun, which can be used sporadically, so don’t go too aggressive on him. He will likely use Galick Gun after Mach Slash later, as well as a stun maneuver. Win and the substory will be over.
