Worship Me! Give Praise Unto Me! The Explosive Birth of a Merged Zamasu!

Vegeta continues to overpower Goku Black until the villain channels his own rage into a new weapon: a scythe-shaped energy blade forged by plunging his Aura Slide into his own hand. A single swing of this scythe tears open a massive rift in reality, a void that even Goku Black cannot identify. From this rift pour shadow clones that overwhelm both Goku and Vegeta, endlessly regenerating no matter how many are destroyed.

While the Saiyans are trapped, Future Zamasu breaks off to hunt the others. Bulma devises a counterstrategy: she has Piccolo's demonstration of the Evil Containment Wave recorded on her phone and coaches Future Trunks through learning the technique on the spot. After several failed attempts mimicking silly poses, Future Trunks watches the recording and masters the wave. When Future Zamasu corners them, Bulma buys time by trying to flirt with the corrupt god, then stalling him physically. Future Trunks unleashes the Evil Containment Wave, spiraling Future Zamasu into the urn with Future Mai's help.

Victory seems at hand until they realize the sealing talisman was left behind in the present. Master Roshi is shown calling Capsule Corporation about the forgotten talisman, and Piccolo calls Goku an idiot upon hearing the news. Without the talisman, the seal fails, and Future Zamasu bursts free. Sensing his partner's distress, Goku Black abandons his clones via Instant Transmission, collapsing the rift. With their options exhausted, Future Zamasu and Goku Black take the desperate measure of using their Potara earrings to fuse, merging into a single, terrifyingly powerful entity: Fused Zamasu.

The Evil Containment Wave sequence is simultaneously thrilling and agonizing. Future Trunks learns a technique in minutes that took others years to master, only for the entire plan to collapse over a forgotten piece of paper. This is classic Dragon Ball tension, where a single overlooked detail unravels a perfect strategy. Bulma's contributions throughout this episode deserve recognition: she recorded the technique, coached Trunks, stalled Zamasu, and maintained her composure under the most terrifying circumstances. Her bravery rivals that of the Saiyans, even without their power.

The Potara fusion between Goku Black and Future Zamasu represents their acknowledgment that the mortals are more dangerous than anticipated. Future Zamasu himself admits they cannot afford to be careless. By combining an immortal body with Goku Black's ever-growing Saiyan power, they create a being that theoretically has no weakness. Gowasu and Shin recognize the Potara instantly, understanding the catastrophic implications. The episode positions the fusion as the saga's point of no return, escalating the conflict beyond what any individual fighter can handle.
