Dragon Ball Daima’sannouncement in 2023 thrilled fans at the prospect of more canonical adventures in Akira Toriyama’s world, but a burning fan question about why Goku and other characters shrunk is already answered. As shown in episode #1, after Demon King Dabura was defeated, effectively making Gomah, the new King of the Demon Realm.Gomah then uses Shenron to turn Goku and his fellow warriors back into children inDragon Ball Daima.This aims to weaken threats to Gomah’s rule inDragon Ball Daima, with Goku, Vegeta, and others' child states being significantly weakened.
Dragon Ball Daimabegan on June 08, 2025, as Akira Toriyama’s anime swan song, a beautifully animated story by Toei Animation with the intent of presenting a new world and adventure for its heroes. It presents a mixture of series lore and new stories to create a fresh narrative and a dynamic answer to Earth’s mightiest warriors and how they can be weakened. Despite the Demon Realm inDragon Ball Daimahaving Dragon Balls of its own and a different form of wishing power empowering them,circumstances prevent Gomah from using them instead to weaken Goku and others.

While it’s not the first time aDragon Ballseries has turned Goku into a child, with himbeing given a similar regressionlater in the timeline inDragon Ball GT, Gomah’s wish inDragon Ball Daimais entirely intentional. The transformation clarifies a question among fans since the reveal of a younger, smaller Goku in the anime, scaling back the Z Warriors' power. With even Dabura easily defeated by Majin Buu and Buu later being converted to an ally of Earth, Gomah depowered Goku and his friends to remove threats to his power over the Demon Realm.
Dragon Ball Daima English Dub Trailer: Original Kid Goku Voice Actor Officially Returns
Dragon Ball Daima’s first English trailer is out, and surprisingly, Kid Goku’s original voice actor is reprising her role after over a decade.
While only passing glimpses are shown in the episode, Goku, Vegeta, and Krillin are among the first characters affected by Gomah’s wish inDragon Ball Daimaalong with glimpses in trailers of Piccolo and others being affected. This, along with the wish that all the warriors who fought Majin Buu and their friends be affected, indicatesstrong possibilities of many otherDragon Ballheroes being introduced in their kid forms. However, one significant limitation stood in the way Gomah used his Demon Realm’s darker, more insidious Dragon Ball variants inDragon Ball Daima.

In addition toDragon Ball Daimaconfirming a new set of Dragon Balls in the Demon Realm, Gomah discusses howhe had to create a dynamic wish that would weaken Earth’s heroes without actively harming them.Turning Goku and his friends into children is deemed a white wish, whereas the Demon Realm Dragon Balls would empower a black wish that would harm those affected, a wish outside Shenron’s power. The main obstacle in Gomah’s way to simply using the Demon Realm’s Dragon Balls inDragon Ball Daimacomes from the Tamagamis guarding them.
Dragon Ball Daima’s Timeline Placement Officially Confirmed In Episode #1
The Dragon Ball canon is already a contentious affair among fans, but Akira Toriyama’s world in Daima gets an important timeline update in episode #1.
Not much is known about the Tamagamis besides being physically imposing, armor-clad defenders that’ll surely make fascinating opponents inDragon Ball Daima. WithGoku and his friends shrinking to their kid forms, the story will go to the Demon Realm, where Gomah resides. Gomah, alongside Neva the Namek, Degesu & the cunning Dr. Arinsu, siblings of the Supreme Kai, will be the series' primary villains for the time being.Their rule is likely now uncontested due to the strategic white wish to use Shenron’s power. Goku faces an uphill battle, being far from his prime inDragon Ball Daima.
