Ultraman Zearth (ウルトラマンゼアス, Urutoraman Zeasu) is a Japanese superhero film celebrates that serves as the 30th anniversary of the Ultraman Series.


An Ultraman from the Land of Pikari in Nebula Z95, Zearth came to the planet Earth to defend it from the forces of evil, creating the human identity Katsuto Asahi, a member of MYDO, an Earth defense team that used a gas station as their secret base. Due to his fear of dirt he was placed in the lowest position in the team, the janitor. His occupation as a janitor appealed to the dirt fearing Zearth’s own love of cleanliness. The fact no one took him seriously didn’t bother him, since he was not allowed to go out on missions, it gave him the chance to transform out of sight.

When the dreaded Cotton-Poppe attacked Japan, Zearth transformed to practice in the Japanese country side while MYDO searched for the monster, accidentally falling into mud and desperately washing it off, unknowingly letting the evil Alien Benzene know of his phobia. Soon the vile alien used this to discover the truth of Zearth’s human form and continued to torment him with tar. Benzene soon captured a group of children and Zearth's love interest, luring Zearth to fight his monster with the plan that the explosion from his beam would destroy the Earth, leaving Zearth VS BenCotton Zearth fighting Benzene and his monstrous servant

MYDO caugt up with Zearth and warned him of the scheme. With the barrier blocking him, the only way to get to the hostages was to cross a huge pool of tar to rescue them. Zearth tried but his crippling fear caused him to sink, his color timer blinking rapidly, disappearing below the surface. It seemed the Ultra hero was doomed but MYDO and the children cheered for the hero, giving him strength. His love interest remembered Katsuto's words of how he felt stronger by hear her flute played with all her heart. Restored, the mighty giant erupted forth back at full power, doing battle with the vile kaiju, proving his strength. He eventually knocked out Cotton-Poppe with the Zearth Knee Strike, then used the Super Zearth Kick to send Benzene flying into outer space before lifting Cotton-Poppe and taking him into space, safely using the Speshusshura Beam to obliterate the beast, while its master drifted through space.
