Despite being a game that's supposed to be all about Goku -- his Saiyan name's even in the title -- Dragon Ball Z: Kakarot will feature multiple playable characters. According to the latest issue of V-Jump, as translated by Gematsu, you'll also be able to take control of Gohan, Piccolo, and Vegeta.
It's unclear how this will all work, but we're assuming that the other characters will only be playable at certain points in the story. It's also been confirmed that Krillin, Yamcha, Tien, and Chiaotzu will be support characters only.
With gamescom coming up soon, we're probably getting new Dragon Ball Z: Kakarot gameplay in the near future, so we'll be keeping an eye out for any updates. In the meantime, dibs on Vegeta in the comments section below.
