"Parasa parasa!"

―Booska's catchphrase

Booska (ブースカ, Būsuka) is the titular main protagonist of Kaiju Booska. He is a mutated iguana whose unusual abilities comes from his crown and later on befriends a mutated squirrel/alien hybrid named Chamegon. At the end of the series, the two departed to space, promising to return 20 years later.

Booska and his series enjoy a huge popularity despite being aired on the same period as Ultraman and he is also a popular icon of Tsuburaya to this day. Booska himself has made several cameos and other shown within the Ultraman Series continuity.

Subtitle: Friendly Beast (快獣, Kai Jū)


Kaiju Booska

Booska began life as a pet iguana to a Japanese kid named Daisaku Tonda who liked to play mad scientist. He made some kind of food called Kuropara and fed it to the Iguana. This resulted in the reptile growing into a man-sized friendly Kaiju named Booska. Booska and Daisaku would go off on adventures and fight off the monster of the week. The show was incredibly popular for the time, but was off the air in 1967, where, at the end of the series, both Booska and Chamergon went into space in a rocket ship. Kaiju Booska

Booska's Back!

30 years later, hearing that he had been forgotten, Booska flew back to Earth. He was shocked by how much Japan had changed as he searched for his old friends. He eventually encountered an now adult Chorokichi, and they searched for the others together, but had no luck. Booska was disheartened, wondering if even his friends had forgotten him, as they sat by a river together. Wanting to play with friends again, he asked a nearby group of kids if he could play with them, but they were not interested and left, leaving him dejected once more. However, a mailman appeared and gave him a letter from Daisaku. Daisaku welcomed him back to Earth, but apologized for being too busy to see him himself. Chorokichi assured him this meant that Daisaku had become a hard-working adult, just as he had promised years ago. Also noticing that the letter smelt like Daisaku, Booska was brought to tears. Booska's Back!

Booska! Booska!!

After almost fourty years, the series was revived and Booska once again, with a similar origin story. However, he didn't face as many other monsters as he did in his series and lost his good friend, Chamegon. Booska! Booska!!

Ultraman Dyna: The Return of Hanejiro

Booska and Kamosuke had made a cameo appearance in the special where they worked as a waiter at a restaurant, serving ramen for the trio of human-disguised Alien Miji before they get away after their human disguises wear off, much to everyone's confusion. He also witnessed Ultraman Dyna's battle with Arwon, later against One-Z. Ultraman Dyna: The Return of Hanejiro

Ultraman R/B


Booska is the "Great Leader" of an alien alliance, arriving on Earth with Dada and Pigmon. He was upset that aliens and Ultramen had been fighting for so long, so he wanted to set up a thank you party so that everyone can get along. However, Dada couldn't help himself after learning that the Minato brothers were Ultraman Rosso and Ultraman Blu, and so he fought them after losing his temper. After Dada was defeated, Pigmon went to get Booska and told him about what happened.

Booska was disappointed in Dada's behavior and shrank him down into a containment chamber, telling him to think about what he has done. Booska then apologized on Dada's behalf, explained his presence on Earth, and then invited everyone to his next party. Everyone Is Friends

  • Boo Power: Booska's primary ability, instrumental to countless other abilities he has. When in a real pinch or angry, Booska chants his signature 'KA.KA...KA!', and the spout on his head erupts a jet of steam.
