Dragon Ball Z Shuts Down Super Saiyan 4 Goku Theory Ahead of 2026 Comeback

In Dragon Ball DAIMA Episode 20, Goku strongly suggests he achieved the Super Saiyan 4 transformation after his battle with Kid Buu at the end of Dragon Ball Z. He explains, “Buu was incredibly powerful, so I trained extensively afterward. I wasn’t certain if it would pay off.” This “it” likely refers to becoming Super Saiyan 4. However, the game Dragon Ball Z: Kakarot has changed this established story with a new scene after the credits. According to the game, Goku didn’t first transform into Super Saiyan 4 until Neva assisted him.
