Superior Ultra 8 Brothers

On July 17, 1966, Daigo Madoka, Shin Asuka, and Gamu Takayama watch the first broadcast of Ultraman, inspiring them to pursue great dreams. They discuss their ambitions: Asuka wants to be a pro baseball player, Daigo dreams of becoming an astronaut, and Gamu aspires to be a scientist to build a ship for Daigo. A strange girl appears but doesn't share her wish, bidding farewell before disappearing.

Decades later, the friends have forgotten their childhood dreams and live normal civilian lives. Daigo rushes late to work, then witnesses a strange mirage over Yokohama revealing a destroyed city and Ultramen fighting Kaiju. The vision appears to be from a parallel universe where Ultraman exists and battles alien threats.

Daigo experiences another vision of a battle between Ultraman Mebius and Neo-U-Killersaurus. A mysterious supporter claims to know Daigo and suggests he's glimpsing a parallel universe where Ultraman is real. Daigo also notices the strange girl from his childhood and a dark-robed man causing chaos.

A rogue man in dark robes causes a truck to careen towards children. Ultraman Hayata, Dan Moroboshi, Hideki Go, and Seiji Hokuto quickly intervene, stopping the truck effortlessly. The villain laughs and vanishes, indicating an ongoing threat from another universe.

While guiding tourists, Daigo sees King Guesra rising from the sea to attack, reminiscent of the original Ultraman episode. Ultraman Mebius appears to fight Guesra but is quickly overpowered. Daigo's advice helps Mebius defeat Guesra, illustrating his deep connection to Ultraman's history.

Daigo encounters Mirai Hibino, who appears as Ultraman Mebius but is confused about how he arrived from his universe. Mirai warns Daigo of the threat posed by monsters summoned from his world, setting the stage for a multi-dimensional crisis.

King Pandon rampages through Yokohama, causing destruction. Mirai transforms into Mebius and fights Pandon, aided by Daigo and others. After intense combat, Mebius and the Ultramen defeat Pandon, but Mebius is frozen by Alien Hipporit, signaling escalating danger.

Gloom settles over the city as injured civilians and feelings of hopelessness grow. Rena and others inspire the people to believe in their dreams and hope. Daigo’s childhood memories resurface, leading him to realize he is the rightful Ultraman hero, transforming into Ultraman Tiga.

With renewed hope, Daigo as Ultraman Tiga and other Ultra heroes like Gamu and Asuka transform into Dyna and Gaia. They battle resurrected monsters and Giga Chimaira, eventually overpowering the enemies with combined Ultraman powers, restoring peace to Yokohama.

The Ultramen defeat the cloaked beings attempting to destroy all Ultraman across universes. As the enemies are vanquished, Mirai Hibino returns to his universe, promising to see Daigo and his friends again. Their efforts affirm that belief and dreams are crucial for Ultraman's existence.

Years later, Asuka becomes a professional baseball player, Gamu a successful scientist, and Daigo fulfills his dream of being an astronaut, marrying Rena. Their daughter Hikari meets the girl with red shoes, symbolizing the continuation of hope and dreams across generations.

The story concludes with Daigo and his friends boarding a spaceship, heading toward M78, the Ultraman homeworld. The ship’s launch symbolizes the ongoing adventures and the enduring spirit of heroism, reinforced by the universal appeal of Ultraman.
