Pestar (ペスター Pesutā) is a Kaiju that fed upon oil and attacked several oil rigs to quench itself. After it was lured onto land, he was knocked out by the SSSP. Later, he was destroyed by Ultraman, who proceeded to undo the damage Pestar had done.

Pestar appears

Pestar was an aquatic monster that had been preying on oil tankers that wandered too close to his territory for a while. He was first spotted by a drunk man, who tried to alert the authorities, but was dismissed for being intoxicated. Once the Science Patrol heard about the monster and noticed the connection to the disappearance of oil tankers, they were called into action to deal with the monster. They first attempted to lure the monster out of hiding with oil barrels from a nearby oil refinery, but it took a long time to lure the monster out of hiding as it was suspicious of the Science Patrol's actions, and fed once the VTOL vehicles were running out of fuel.

Suddenly, a missile was fired by mistake at the monster while it was feeding. Provoked and angry, Pestar headed for the oil refinery and set it ablaze with his flames. Reacting quickly, the monster, due to smoke inhalation, was knocked  unconscious. With the flames now out of control at the refinery, the Science Patrol was forced to leave Pestar to deal with the inferno. Luckily, Hayata transformed into Ultraman and managed to put out the fire with ease. Pestar however, was not finished and feebly fired behind Ultraman's back with his flames. However, this proved futile and Ultraman retaliated with the Specium Ray, killing Pestar easily, and leaving Ultraman to finish extinguishing the fire.


  • Pestar's name is a combination of Petroleum and Starfish.
  • Pestar's costume is the second in the Ultraman series to be piloted by two suit actors, the first costume was Dodongo.
  • Pestar's cry is a modified Mothra cry.
  • Although the credits of Oil S.O.S. credited the provider of the special effects in Takano Koichi's name, it was actually the show's director, Hajime Tsuburaya who was in charge of the episode's effects. Concurrently, Tsuburaya had the quick-witted and unique idea for the costume to have two people in it.
    • Originally, Pestar was to have two heads, but was eventually given one to give him a more bat-like appearance.
  • Pestar's two-man appearance would later inspire monsters such as Menjura from Ultraman Tiga, and Antimatter from Ultraman Gaia.
  • Although not physically seen, Pestar is one of the monsters that makes up Belyudra's body in Mega Monster Battle: Ultra Galaxy Legends The Movie.
  • Pestar's Spark Doll can be seen in the second Ultraman Ginga: Theater Special.

Ultraman: The Ultimate Hero


Pestar, as seen in Ultraman: The Ultimate Hero

Pestar reappeared in episode 10 of the series, Ultraman: The Ultimate Hero as Powered Pestar (パワードペスター Pawādo Pesutā). Episode 10 is named "Deadly Starfish", which references Pestar's starfish-like appearance.

Much like the original kaiju, Pestar was an aquatic monster that had been feeding on oil tankers that passed by his territory. WINR at first tried to pursue and stop Pestar using a submarine known as the "Barracuda" but Pestar's size caught them off guard. After a brief tussle, Pestar escaped. The next night, Pestar reappeared and attacked an oil refinery to feed on its oil, but Ultraman Powered appears in time and destroys Pestar by tossing him into the air and firing his Mega Specium Ray at the kaiju.


  • In this series, Pestar's head no longer resembles a bat's head, it looks more Crustacean-like, but almost like a bat if one looks closely. The edges of his body are also surrounded with tube feet.

Pestar was among the dormant Spark Dolls that were buried under the Earth and ocean. But after a strange solar flare bathed the Earth, it awakened every Spark Dolls as they terrorize the Earth. Pestar was among the rampaging monsters and was first seen attacking at an oil refinery in the Middle East.

Pestar reappeared as a Cyber Card in the final episode of Ultraman X. After Ultraman X spoke out to Gomora and striked Greeza right in the center of his chest, Pestar, along with all of the other Cyber Cards, traveled to X and united with him. Cyber Pestar's power was used to help form the Hybrid Armor and power up the Ultimate Xanadium to defeat Greeza once and for all. Pestar, along with the numerous other Cyber Cards and Spark Dolls, then appeared and thanked Daichi as he thanked them.The Rainbow Land


  • It is possible that Pestar's attack in the Middle East was due to the region being one of the top producers of petroleum, fitting with Pestar's diet.
  • Pestar's suit is actually the new stage show suit of the monster.
