He arrived on Earth to guard it from the evil interdimensional entity Yapool and their many Terrible-Monsters. When Ace arrived on Earth, he merged with a man, Seiji Hokuto, and a woman, Yuko Minami. Ace is known for his many beam techniques, which earned him his subtitle. He is the adopted son of Father of Ultra. He is the godfather of Ultraman Z.
