I first learned his name back when I was a kid and a game that he did the artwork for that was going to be on the cover of “Game Informer magazine” ended up being denied because they did not want his artwork on the cover and it caused a controversy. The game was called “Chrono Trigger.” I can see the similarity of the artwork and character designs to the Dragon Ball characters.
His first game that I’m aware of is Dragonwarrior I.
