Galick Cannon was first named in Dragon Ball Heroes. In Dragon Ball Xenoverse 2, Galick Cannon appears as a Super Skill used by Cabba which can be obtained by the Future Warrior by purchasing it from the TP Medal Shop for 30 TP Medals. Despite its description stating it is identical to the Galick Gun, in Xenoverse 2 it functions differently than the Galick Gun Super Skill as Galick Cannon requires the use to tap the assigned button to build up more power (the Galick Gun can be charged by simply holding the button).
