Ultraman, featured in the OVA *Ultraman: Chō Tōshi Gekiden - Suisei Senjin Tsuifon Tōjō*, emerges as a cosmic guardian battling Tsuifon, a primordial force of destruction residing within a comet. For millennia, Tsuifon has cycled through the cosmos, obliterating entire worlds. When Earth’s defenses prove futile against the comet’s approach, Ultraman strategically lures the entity to the Moon with allied support. Despite his efforts, Tsuifon ascends into Super Tsuifon, a heightened state that overwhelms Ultraman, shattering his Color Timer and leaving him mortally wounded.

Facing annihilation, Ultraman activates the forbidden Ultra Crown, sacrificing his life force to amplify his strength. Yet even this desperate gambit fails. As he nears defeat, humanity’s collective hope reignites his power, resurrecting him with the Delta Star armor—a celestial enhancement that counters Tsuifon’s devastating drill attacks. Empowered, Ultraman severs the entity’s horns and unleashes the Spacium Super Lightwave, obliterating Tsuifon and halting its eternal rampage.

His design adheres to classic lore: a humanoid warrior whose Color Timer monitors dwindling energy, requiring symbiosis with a human host to maintain his Earthly presence. Combat blends raw physicality with energy-based strikes, including the signature Spacium Beam reimagined as the Spacium Super Lightwave. The narrative underscores his unwavering resolve as a protector, willing to embrace self-destruction for others’ survival, while humanity’s faith catalyzes his ultimate triumph.

No additional details about his origins or alternate media portrayals within this specific iteration are provided.
