The finale of *Dragon Ball Daima* showcases an intense showdown between Gomah and Goku, who unveils a new form that fans eagerly anticipated might connect to the Super Saiyan 4 transformation. In the climactic episode, the Z Fighters revert to their adult forms thanks to Glorio's wish. Vegeta attempts to confront Gomah solo but can't overpower him even with his Super Saiyan 3 form. It's then up to Goku, who harnesses the power bestowed by Neva in the previous episode, which he dubs "Super Saiyan 4."
Goku utilizes this form to battle Gomah, managing to hold his ground. With a powerful Kamehameha, he pierces through Gomah and the Demon Realm, setting the stage for Piccolo to intervene and strike at Gomah's eye. Although Piccolo doesn't finish the job, Majin Kuu delivers the final blow, ending Gomah's reign over the Demon Realm.
Despite the expectation that *Dragon Ball Daima* would clarify the absence of Super Saiyan 4 in *Dragon Ball Super*, the series takes a different route. Goku casually mentions to Vegeta that he achieved this new form through regular training post-Buu saga, without any special conditions or mind-wipes, leaving fans puzzled about its canon status relative to *Dragon Ball Super*.
Is Dragon Ball Daima Canon to Super?
The introduction of Super Saiyan 4 in *Daima* poses significant questions about its canonical relationship with *Dragon Ball Super*. If Goku had access to such a formidable form, why didn't he use it against Beerus in *Super*, especially when the planet's fate hung in the balance? The absence of any memory manipulation or clear explanation creates a potential plot hole that could fuel debates among fans.
A glimmer of hope appears in the post-credits scene of the *Dragon Ball Daima* finale, which hints at the possibility of a future season. It reveals that two more Evil Third Eyes remain in the Demon Realm. If these artifacts fall into the wrong hands in a subsequent season, it could provide a narrative pathway for Super Saiyan 4's reintroduction and possible loss, though this remains speculative at this stage.
Thus, *Dragon Ball Daima*'s finale does not directly address why Goku never uses Super Saiyan 4 in *Dragon Ball Super*, instead leaving the door open for future developments. For those interested in exploring more of the series, *Dragon Ball Daima* is currently streaming on Crunchyroll.
