Jamila

Jamila is an alien monster in the Ultraman franchise, first appearing in episode 23.

Ultraman
Jamila was originally a human astronaut who got lost in a satellite before landing on an alien planet deprived of water and air and mutating into an alien monster.

Seeking revenge against the science community for abandoning him, Jamila headed to Earth to attack a peace conference between the U.S. and Russia. He was ambushed by the Science Patrol but their weapons had no affect on him and Jamila managed to escape into the forest.

The Army later attacked Jamila with flamethrowers, but they had no affect on him. Jamila turned his attention to a nearby village and rampaged through it. Soon after, he attacked the World Peace Conference in Tokyo. Ultraman soon showed up and the two fought. They were initially evenly matched until Ultraman unleashed the Ultra-Shower on him, allowing him to subdue the monster. As Jamila writhed in agony, Ultraman and the Science Patrol realized that he was merely a victim of circumstance and gave him a proper burial, as well as mounted a plaque in his honor.

Ultraman Taro
Jamila is seen in a flashback in episode 25 as a part of the Empera Army led by Alien Empera during the Great Ultra War.
