A Giant of Light who appears after the protagonist, Yuma, unleashes his imagination and unites with Rution, the being of light from a faraway galaxy. His appearance is exactly the same as Yuma’s childhood sketch of the “Strongest Hero.” Yuma transforms into Ultraman Arc by inserting the Arc Cube, infused with power, into the Arc Ariser, which resembles his other sketch of the “Transformation Item,” and unleashing the light.
