Ultraman Zearth

Ultraman Zearth is a parody of Ultraman. He hails from the Land of Pikari in Nebula Z95. He has a big red face and dislikes dirt, and will go to great lengths to wash it off his hands. His goal is to clean the polluted Earth. Zearth appears in two movies: Ultraman Zearth (March 9, 1996) and Ultraman Zearth 2: Superman Big Battle - Light and Shadow (ウルトラマンゼアス2 超人大戦 光と影 Urutoraman Zeasu Tsū Chōjin Taisen Hikari to Kage) (April 12, 1997). The second movie is the one that involves mind control.

Ultraman Zearth 2: Superman Big Battle-Light and Shadow
Lady Benzene arrives to take revenge on Ultraman Zearth for sending her husband, Lord Benzene, into space. Benzene sends her underling Ultraman Shadow to attack the hero; Zearth gets ambushed, defeated and a bloodshot eye in Antarctica by Shadow. The battle left Zearth emotionally crushed and unable to fight due to a complete terror of Shadow. But, after receiving a message from his father, as well as a capsule monster named Miraclon, Zearth decides to train and become powerful enough to face the evil android. But there's not enough time to gain enough training as Shadow reappears in the city. Zearth hadn't yet overcome his fear of Shadow enough to combat him. Instead, Zearth sends his capsule monster to fight for him. Miraclon defeats Shadow's capsule monster Darklar but is defeated by Shadow, forcing him to be recalled, allowing Shadow to enslave the city for his mistress, including Katsuto's love interest. After a great deal of training, Katsuto regains confidence and transforms into Ultraman Zearth to battle his doppelganger. The two collide in an epic battle in Shadow City, Lady-Benzene's base, with Zearth's training allowing him to overwhelm his nemesis, sending him plummeting from the sky with his newly developed Ultra Heel Drop, damaging his head, revealing the circuitry inside and seemingly defeating Shadow. Lady-Benzene commands Shadow to rise again, recharging him. The two fire their finishing beams against each other, this time they were evenly matched but with a boost from Lady-Benzene, Shadow begins to overpower Zearth. With the voices of millions chanting behind him, Zearth gains enough strength and uses the mighty Cross Speshusshura Ray. The attack slammed through Shadow's ray, finally slamming into his body and blowing the robot apart. After the battle, Lady-Benzene appears, congratulating Zearth for defeating Shadow but telling him it is far from over and she'll be back to conquer the Earth before she left in a shower of golden particles. Zearth restores the minds of all the enslaved humans and takes them home before leaving himself, with newfound inner strength. He will be the Earth's protector should the people of Benzene try to attack the planet again.
