Ultraman Ace

From another dimension, Yapool orchestrated attacks on Earth using biological weapons called "Terrible-Monsters" (超獣, Chōjū) that surpassed ordinary monsters. The first Terrible-Monster Verokron managed to destroy a city and the Earth Defense Force (地球防衛軍, Chikyū Bōeigun) that was dispatched to fight it. A pair of youths Seiji Hokuto and Yuko Minami lost their lives in protecting nearby civilians as the fifth Ultra from M78, Ultraman Ace fused with them. The pair were given Ultra Rings (ウルトラリング, Urutora Ringu) each per person and transforms into Ace whenever they perform the Ultra Touch (ウルトラタッチ, Urutora Tatchi).[1] Ever since Ultraman Ace fought on Earth, Seiji and Yuko were enlisted into TAC (Terrible-monster Attacking Crew) with the Ultra Brothers and Father of Ultra occasionally appeared to help them. Yapool on the other hand would send more Terrible-Monsters, including external help from various forces and occasionally went face-to-face with TAC and Ace themselves.

In the middle of the series, Yuko was revealed to be one of the last natives from the moon and gave her Ultra Ring to Hokuto, leaving the Earth in episode 28 as Hokuto was on his own in succeeding episodes. In the final episode, Yapool masqueraded as the child of Alien Simon and combined several of his past Terrible-Monsters into Jumbo King. When Yapool allowed himself to be killed as the children lost their faith in Seiji, the latter exposed his identity to them and fought the chimeric monster, eventually triumphing over Jumbo King. With Yapool's first (of what would become many) attempts at taking over the Earth thwarted at last, Ace departed the Earth to return home.
