The climactic battle in *Dragon Ball Daima*'s finale pits Gomah against Goku, showcasing Goku's newly acquired form. Many anticipated this episode would finally explain Super Saiyan 4's absence from *Super*. So, how does the finale address this?
Episode 19 sees the Z Fighters revert to their adult forms after Glorio's wish. Vegeta's attempt to defeat Gomah, even as a Super Saiyan 3, fails. Goku steps in, harnessing the power Neva granted him, a power he later calls "Super Saiyan 4."
In this form, Goku battles Gomah, holding his own. His Kamehameha blasts a hole through Gomah and the Demon Realm, allowing Piccolo to strike. While Piccolo doesn't deliver the final blow, Majin Kuu does, defeating Gomah and freeing the Demon Realm.
The series seemingly sets up an explanation for Super Saiyan 4 being Demon Realm-exclusive or Neva-specific, but it doesn't. Goku reveals he achieved this form simply through post-Buu training. No memory loss is involved, leaving *Dragon Ball Daima*'s canonicity ambiguous.

Is *Dragon Ball Daima* Canon to *Super*?
Super Saiyan 4's introduction raises questions about *Daima*'s place in the *Dragon Ball* canon. Goku's failure to use this incredibly powerful form against Beerus in *Super*, especially with Earth's fate at stake, is perplexing. While forgetting is possible, Vegeta's reaction to being surpassed again seems unlikely.
However, a potential loophole exists. The post-credits scene reveals two more Evil Third Eyes in the Demon Realm. A future season, involving these objects falling into the wrong hands, could offer a way to reintroduce and subsequently explain away Super Saiyan 4. This remains speculation, but its absence creates a significant plot hole.
This is how *Dragon Ball Daima*'s finale handles Goku's lack of Super Saiyan 4 in *Super*. For those interested, here's a link to the anime's intro song.
