Question: how to get ssj in xenoverse 2?
Answer: Vegeta is also located in the Capsule Corp. time rift. Head over there and he'll want to fight you every now and then. After fighting and beating him a second time, you'll get the chance to get the Super Saiyan ability from second mission, "Saiyan Awakening", once you've spoken to his family (Bulma and Trunks).
