The climactic battle in *Dragon Ball Daima*'s finale pits Gomah against Goku, who unveils a shocking new transformation. Many viewers anticipated an explanation for Super Saiyan 4's absence in *Super*, and the finale attempts to address this.
Episode 19 shows the Z Fighters reverting to their adult forms after Glorio's wish. Vegeta's Super Saiyan 3 assault on Gomah fails, leaving Goku to utilize the power Neva granted him—a form he calls "Super Saiyan 4." This form allows Goku to hold his own against Gomah, ultimately blasting a hole through his opponent and the Demon Realm, paving the way for Piccolo and Majin Kuu to deliver the final blows and defeat Gomah.
While the narrative seems poised to explain Super Saiyan 4 as Demon Realm-exclusive or somehow tied to Neva, it takes a different turn. Goku reveals he attained the form simply through post-Buu training, with no mention of mind-wiping, leaving the canonicity of *Dragon Ball Daima* 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. Goku's failure to utilize such a powerful form against Beerus in *Super*, especially with Earth's fate at stake, is a glaring inconsistency. While forgetting it is possible, Vegeta's reaction to being surpassed again would likely be far more pronounced.
However, a post-credits scene hinting at two more Evil Third Eyes in the Demon Realm offers a potential escape clause. A future season exploring these objects could provide a mechanism for Super Saiyan 4's return and subsequent loss by Goku. This remains speculation, but its absence risks creating a significant plot hole.
Thus, *Dragon Ball Daima*'s finale offers a somewhat unconvincing explanation for Goku's lack of Super Saiyan 4 in *Super*. For those interested in further details, the anime's intro song is also available.
Dragon Ball Daima is streaming now on Crunchyroll.
