Dragon Ball Daimacontinues to surprise fans by introducing changes to the franchise’s lore that build upon familiar elements. Rather than discarding Akira Toriyama’s original foundation, Daima embraces it, enhancing and expanding upon what was already established. The latest twist, featuringVegeta achieving the Super Saiyan 3 transformationthat the fandom has dreamed of for decades, highlights how Daima is gradually refining and enriching the series' lore.
One of the most significant changes inDragon Ball Daimaso far is the retconning of Buu, which has proven to be immensely impactful. This change introducednew iterations of the iconic villain: Majin Kuu and Majin Duu. While Majin Kuu defied fan expectations, Majin Duu has emerged as a formidable antagonist in the latest arc. However, the subtle hints scattered across the last 12 episodes, coupled with Majin Kuu’s high IQ and Majin Duu’s formidable strength, suggest that an even greater villain is being set up for the Z fighters.

Dragon Ball Daima’s Next Big Villain Could Be the Fusion of Majin Kuu and Maijn Duu
Majin Kuu and Majin Duu’s Fusion Would Be a Perfect Villain
Dragon Ball DaimaEpisode #12, “True Strength”, continues Majin Duu’s fight with the Tamagami Number #1, presumed to be one of the strongest characters of Daima so far. Arinsu’s second attempt at creating a controlled replica of Majin Buu resulted in Majin Duu, who exhibits behavior far closer to the original Majin Buu than Majin Kuu ever did. During the fight, Majin Duu threw a tantrum over eating chocolate but ultimately triumphed against the Tamagami of the First Demon World, who was guarding the Dragon Ball.
This highlights that Majin Duu retains much of the original Majin Buu’s immense strength. Considering it requiredVegeta’s Super Saiyan 3 transformation to defeat the Tamagami, it underscores that Majin Duu’s primary asset lies in his raw power. Meanwhile, Majin Kuu, initially dismissed by fans as a failed result of the experiment to create the next Majin Buu, also proved invaluable in the latest episode. Following Majin Duu’s victory over the Tamagami, the second challenge in the quest for the Dragon Ball emerges, this time testing wit.

The Tamagami’s challenge required solving rapid-fire math problems, leaving Majin Duu completely baffled. However, Majin Kuu quickly provided the correct answer to the seemingly impossible question, securing the Dragon Ball and showcasing his remarkable intelligence. With no formidable villains currently left inDragon Ball Daimaand Goku and Vegeta vying for the opportunity to face the next enemy, a fusion of Majin Duu and Majin Kuu could create a perfect adversary. Such a fusion would pose a genuine threat to the Z Saiyans, delivering an exciting challenge in the latest installment.
Daima Has Already Hinted at Majin Buu and Majin Kuu’s Fusion
The idea of Majin Kuu and Majin Duu fusing might seem unlikely at first, but subtle hints from recent episodes suggest that such a fusion is entirely possible. InEpisode #4 ofDragon Ball Daima, Goku and the others encounter various medicinal bugs with unique effects. While the Revive Bugs function similarly to Senzu Beans, the most intriguing discovery is the Join Bugs. According to the Kind Shopkeeper who sold them to Goku, the Join Bugs enable the fusion of different individuals into a single, more powerful warrior.
Dragon Ball Daima Is Getting Ready to Take Fusions To the Next Level With Help From the Majin
Dragon Ball Daima’s two new villains seem to prelude a return of the Fusion technique but in a completely different form.
With fusion being as simple as consuming the Join Bugs, it’s plausible that if Majin Duu alone fails to challenge Goku or Vegeta—especially now that both Saiyans can transform into Super Saiyan 3—Majin Duu and Majin Kuu could fuse to create a formidable adversary. Combining Duu’s raw strength with Kuu’s intelligence,Dragon Ball Daimacould introduce a villain capable of pushing Goku and Vegeta to their limits, forcing them to grow even stronger. While it’s debatable whether villains could access the Join Bugs, the hidden traits within Majin Duu and Kuu suggest there may be another path to transformation.

The Fusion in Daima Is Inevitable
The fusion of Majin Kuu and Majin Duu hinges on how quickly Arinsu or Kuu realizes they could utilize their native world’s Join Bugs. However, if the Join Bugs fail for some reason,Majin Duu might instead tap into the original Majin Buu’s infamous ability to turn others into chocolate and consume them to gain their strength. With Duu increasingly resembling Buu, it’s only a matter of time before Duu masters Buu’s inherited techniques.
Meanwhile, the Join Bugs could play a pivotal role for Vegeta and Goku, enabling them to fuse to combat the powerful entity born from Duu and Kuu’s fusion. This sets the stage forDragon Ball Daima’s next major villain, a fusion of Duu and Kuu, pushing the heroes to their limits and potentially leading to a legendary new fusion that could become an iconic addition to Toriyama’s legacy.
