It’s been revealed in V-Jump that Goku from Dragon Ball GT will join Dragon Ball FighterZ as its next character joining the mix via DLC. [Thanks, Ryokutya2089.]
Son Goku (GT) has a “Super Kamehameha” special attack that makes him go Super Saiyan 3 form if there are two or fewer members remaining in your party.
His Meteor Attack is “Super Ultra Spirit Bomb” which is slow to shoot, but Goku becomes invulnerable to attacks during the motion. This can be used in a way to protect yourself when you know you’re about to get hit from the enemy.
Goku also has his Power Pole, and a Reverse Kamehameha used as a dash attack. He also has a secret Meteor Attack.
Dragon Ball FighterZ is available on PlayStation 4, Xbox One, Nintendo Switch, and PC.
