News is that Dragon Ball FighterZ will be introducing one more version of Goku to its roster. This time around, it will be Kid Goku from Dragon Ball GT, who was turned into said form because of Shenron shenanigans. The choice is curious for a couple of reasons.

Two, if the people behind Dragon Ball FighterZ wanted a Kid Goku, the logical choice seems like it would be the Kid Goku from the earliest stories in the Dragon Ball franchise. Regardless, the Kid Goku from Dragon Ball GT is on his way, set to make a splash by bringing iconic attacks such as his Power Pole, the Super Spirit Bomb, and the Super Kamehameha.
