Ultraman Mebius & Ultra Brothers 2006

Sealing of Yapool and U-Killersaurus

Twenty years after the lunar battle, the four Ultra brothers are weakened and seal Yapool and U-Killersaurus in Kobe's sea. The victory drains their energy and binds them to human hosts, rendering them unable to transform. They endure mortal lives in Kobe while awaiting Yapool's return.

GUYS arrive in Kobe to investigate

Two decades after the sealing, Mirai Hibino leads the GUYS team into Kobe to investigate troubling events. He meets Aya Jinguji and her younger brother Takato, whose fear of Ultramen has grown after recent attacks. The team begins to uncover a looming threat over the city.

Kelbim attack reveals Takato's trauma

Aya explains that three months earlier Takato and his dog Art were attacked by the monster Kelbim, leaving Takato wary and scarred. The incident strains the family and deepens Takato's reliance on his sister. This backstory heightens the stakes for the present mission.

Bonding and guidance from the Ultra faces

Mirai forms a quiet bond with Takato, and the human-facing Ultra brothers provide patient guidance for the days ahead. Takato's trust grows as he senses the Ultra brothers' concern from beyond their mortal forms. The connection gives the team a glimmer of hope amid rising danger.

Temperor's strike and the line held

The Alien Union makes a first strike with Temperor, who is met with resistance and defeated by Ultraman Mebius. This buys time for the others to regroup. The city braces for further chaos as the invasion continues.

Zarab infiltrates Aya's circle

Zarab infiltrates Aya’s circle, steals her form, and poisons Mirai with a fake drink, turning himself into an impostor Ultraman Mebius. Chaos spreads across Kobe as the deception takes hold. The GUYS team grapples with the betrayal from within.

Zarab's disguise exposed and Zarab defeated

Mirai, recharged, transforms into Mebius, exposes Zarab's disguise, and defeats Zarab in a decisive clash. He is then captured when Guts and Nackle trap the team in crystalline crosses to siphon their energy and revive Yapool.

Crystalline prison and Yapool's revival

With the Ultra Brothers weakened, they are trapped in crystalline crosses that siphon their energy. Yapool is revived as the energy is harvested. The heroes are separated and the threat to Kobe intensifies.

Takato's faith rekindled and Mebius returns

Takato's belief is rekindled, and Mirai transforms again into Mebius to confront Guts and Nackle. He defeats Guts, liberating his fellow heroes from their prisons. Yet Yapool and U-Killersaurus Neo remain a looming danger.

U-Killersaurus Neo escapes; final stand looms

Yapool and U-Killersaurus Neo slip free, triggering a city-wide crisis. The threat escalates toward a final, earth-shaking confrontation in Kobe. The Ultra Brothers brace for a decisive battle to protect the city.

Zoffy and Ultraman Taro join the battle

Commander Zoffy and Ultraman Taro descend to restore energy and join the fight alongside Mirai and the others. Their return strengthens the weakened Ultras and shifts the battle in Kobe's favor. The alliance of legends turns the tide at the climactic moment.

Mebius Infinity saves Aya

Mebius spots Aya trapped within the crystal forehead of U-Killersaurus Neo. The Ultra Brothers fuse with Mirai to become Mebius Infinity, a form powerful enough to save Aya and crush the monster. Yapool vanishes as the creature falls, defeated and powerless.

Aftermath: Kobe saved; farewells and promises

Kobe is saved, and Mirai prepares to return to the Phoenix Nest base. Takato vows to join GUYS when he grows up, while Aya senses something deeper about Mirai's identity and suggests they see each other again. The human-Ultra bond endures as they part ways.
