The climactic battle in Dragon Ball Daima pits Gomah against Goku, showcasing Goku's newly acquired form. While many anticipated an explanation for Super Saiyan 4's absence in Super, the finale offers a surprising resolution.
Following Glorio's wish restoring the Z Fighters to their adult forms, Vegeta's Super Saiyan 3 transformation proves insufficient against Gomah. Goku, leveraging the power bestowed by Neva in the previous episode, unleashes "Super Saiyan 4."
This form allows Goku to effectively combat Gomah, culminating in a Kamehameha blast that breaches the Demon Realm. Piccolo then delivers the finishing blow, freeing the realm.
Instead of establishing Super Saiyan 4 as Demon Realm-exclusive or Neva-specific, the narrative reveals Goku attained the form through post-Buu training. The lack of a mind-wipe leaves Daima's canonicity ambiguous.
The Canon Question:
Super Saiyan 4's introduction raises significant questions about Daima's place within the Dragon Ball canon. Its omission during Goku's fight with Beerus in Super, particularly given the stakes, seems inexplicable. While forgetting is possible, Vegeta's reaction to being surpassed again would likely have been more pronounced.
A potential loophole exists in the post-credits scene, revealing two more Evil Third Eyes within the Demon Realm. A potential second season, involving these artifacts falling into the wrong hands, could provide a mechanism for Super Saiyan 4's return and subsequent loss by Goku. However, without such a development, a significant plot hole remains.
In essence, Dragon Ball Daima's finale explains Super Saiyan 4's absence in Super by attributing its acquisition to post-Buu training, leaving its canon status uncertain and potentially creating a long-lasting debate.
Dragon Ball Daima is currently streaming on Crunchyroll.
