A young Ultra Warrior and the son of Ultra Seven. He detests the stiffness of tradition and longs to live his life freely.
He possesses a speedy fighting style, and fights with light techniques inherited from his father Seven like his special attack Emerium Slash and Wide Zero Shot, as well as the Zero Sluggers. He was also trained in Space Martial Arts by Ultraman Leo and Astra.
As punishment for trying to claim the power of the Plasma Spark Energy Core, the power source of the Land of Light, he is exiled from the Land of Light to spend his days in training with Ultraman Leo and Astra on Planet K76. Later he would fight against Belial, where he would defeat Belial’s monster army and the monster Belyudra that Belial created.
Afterwards he travels to a different Universe and merges with a brave young man, Run. Run transforms into Ultraman Zero by putting on the Ultra Zero Eye, and they go on to fight against Belial’s newly-formed Galactic Empire Army.
