The climactic battle in *Dragon Ball Daima*'s finale pits Gomah against Goku, who unveils a shocking new transformation. Many anticipated this episode would finally explain Super Saiyan 4's absence from *Super*. So, how does *Dragon Ball Daima* address this?
In episode 19, after Glorio's wish restores the Z Fighters to their adult forms, Vegeta's attempt to defeat Gomah—even as a Super Saiyan 3—fails. Goku steps in, harnessing the power Neva bestowed upon him, a power he later calls "Super Saiyan 4."
Utilizing this form, Goku confronts Gomah, holding his own in a fierce battle. His Kamehameha blasts a hole through Gomah and the Demon Realm itself, allowing Piccolo to strike a crucial blow. While Piccolo doesn't deliver the final hit, Majin Kuu does, vanquishing Gomah and freeing the Demon Realm.
At this juncture, viewers might expect an explanation for Super Saiyan 4's apparent Demon Realm exclusivity or its connection to Neva. However, *Daima* subverts expectations. Goku reveals he achieved the transformation simply through post-Buu training. The absence of a mind-wipe leaves *Dragon Ball Daima*'s canon status ambiguous.

Is *Dragon Ball Daima* Canon to *Super*?
Super Saiyan 4's introduction raises significant questions about *Daima*'s place within the *Dragon Ball* canon. It's inconceivable Goku wouldn't have utilized such a powerful form during his battle with Beerus in *Super*, especially with Earth's fate hanging in the balance. While forgetting it is possible, Vegeta's reaction to being surpassed again seems unlikely.
However, a potential loophole exists. The *Daima* finale's post-credits scene reveals the Demon Realm harbors two more Evil Third Eyes. A future season, should one materialize, could see these objects falling into the wrong hands, providing an avenue for Super Saiyan 4's return and subsequent loss by Goku. This remains pure speculation, but its absence leaves a potential plot hole.
Ultimately, this is how *Dragon Ball Daima*'s finale explains Goku's lack of Super Saiyan 4 usage in *Super*. For more details, check out the anime's intro song.
