None; Goku only turns into "level 4" in the DragonBall GT series.
Gogeta, the fusion of super saiyan 4 Goku and Vegeta.
It's not a movie. In Dragon Ball GT, Goku turns super saiyan 4 at the end of season 1 and the beginning of season 2, when he was versing Baby. He remembered his "human" family, changing from the mighty ozaru to super saiyan 4.
it has to be super saiyan 4 Goku but even better is super saiyan 4 Gogeta (fusion of Goku and Vegeta as super saiyan 4) even though it is a fusion they are still transformed saiyans.
Super Saiyan 4 because that is the highest Super Saiyan level in the Dragon Ball official franchise.it is super saiyan 4 when kid goku turns gold ape then gets conscience and turns super saiyan 4
