Universal Conflict Saga

Following the events of the Prison Planet Saga, the Core Area Warriors waste no time pressing their advantage. Hearts, their enigmatic leader, commands the Tuffle twins Oren and Kamin, the ancient Saiyan berserker Cumber, the glass-manipulating Lagss, and the immortal Fused Zamasu. Their goal is audacious beyond measure: to fill the Universe Seed with enough energy to challenge and destroy Zeno himself, the ruler of all existence.

The Assault on Universe 6

The invasion begins in Universe 6, where Oren and Kamin overwhelm Hit, Cabba, Caulifla, and Kale through a terrifying ability. The twins can enter the bodies of wounded fighters and take control, turning allies into enemies through Tuffleization. Vegeta and Future Trunks arrive to reinforce the Universe 6 warriors, but the twins simply possess Caulifla and Kale, forcing their comrades to fight without landing killing blows. Hearts uses his gravitational powers to pin everyone to the ground, declaring that the Universe Seed is nearly complete.

Jiren and the Battle in Universe 11

Hearts reads Hit's mind to identify the strongest mortal in existence: Jiren of Universe 11. The Core Area Warriors shift their campaign to Jiren's territory, where Cumber has already defeated Top. Vegeta and Future Trunks pursue them, only for Oren to possess Vegeta's body and turn the Saiyan prince's power against his own son. Goku arrives from Zeno's Palace in his Ultra Instinct Sign form, effortlessly separating Oren from Vegeta and overwhelming both twins before reverting to base form from exhaustion.

The Final Stand in Universe 7

With the Universe Seed nearing completion, Hearts brings the conflict to Universe 7. Vegeta reaches Super Saiyan God SS Evolved and shatters Kamioren's fusion with a devastating Final Flash. Goku and Hearts clash directly, with Hearts exploiting his mind-reading ability to anticipate every attack. Only when Goku achieves the perfected Ultra Instinct form does the tide turn, allowing the combined might of the Z Fighters to destroy Hearts and the Universe Seed before Zeno can be threatened.

Hearts is a unique villain in the Dragon Ball Heroes franchise because his motivation is not conquest or destruction for its own sake. He genuinely believes that Zeno's power to erase entire universes on a whim is an injustice, and he seeks to liberate all mortals from divine tyranny. His ability to read minds and manipulate gravity makes him a tactical nightmare, and his confrontation with Jiren produces one of the saga's most intense sequences.

The Tuffle twins Oren and Kamin introduce body-horror elements unusual for Dragon Ball. Watching Caulifla and Kale turned against their friends through Tuffleization creates genuine tension, and Oren's possession of Vegeta forces Goku into the uncomfortable position of fighting his rival's hijacked body. Vegeta's ability to force Oren out through sheer willpower alone is a defining character moment that reinforces the Saiyan prince's indomitable spirit.

Cumber's battles with Jiren and the various Saiyan warriors showcase raw berserker power pushed to its limits. His Super Saiyan 3 Full Power form represents an ancient, primal approach to Saiyan combat that contrasts sharply with the refined god-ki transformations Goku and Vegeta have achieved.

The Universal Conflict Saga represents Super Dragon Ball Heroes at its most ambitious, spanning three universes and juggling a massive cast of fighters from across the franchise. It demonstrates the promotional anime's willingness to deliver fan-service matchups that the main series cannot, such as Jiren fighting alongside Goku and Vegeta rather than against them, or Fused Zamasu appearing as a subordinate rather than a primary threat.

The saga's legacy within the Heroes continuity is the completion of the Universe Seed arc and the setup for the Universe Creation Saga that follows. Hearts' defeat does not resolve the underlying tension between mortals and gods that his rebellion exposed, and Fu's continued machinations in the background ensure that the multiverse remains unstable. For fans of the expanded Dragon Ball universe, this saga delivers spectacle, cross-universe team-ups, and transformations at a pace the main series would never attempt.
