I am the fifth of the Ultra Brothers to arrive on Earth. I was the first, and so far, only Ultra to possess two human hosts at the same time. I arrived on Earth to guard it from the evil interdimensional entity Yapool and their many Terrible-Monsters, aka Chōjū. When I arrived on Earth, he merged with a man, Seiji Hokuto, and a woman, Yuko Minami, however Minami had to depart to her home, the moon. I am known for my many beam techniques, earning me the title of the Master of Beam Techniques.
