Seabozu (シーボーズ Shībōzu?) is a kaiju that appeared on the Ultraman series. Seabozu appears in Episode 35.

Subtitle: Ghost Monster (亡霊怪獣 Bōrei Kaijū?)



A disturbance from outer space, the Science Patrol investigated the matter to find themselves in the Monster Graveyard, where all aliens and monsters go when they are destroyed by the Ultramen. Nearly all of them except a skeleton-like monster could be identified.

As they returned to Earth, the skeleton monster dubbed "Seabozu," fell from the sky and landed in a nearby city. As The Science Patrol was about to fire, they noticed that the monster wasn't intentionally attacking the city nor trying to harm anyone, but instead it climbed the tallest building in the city as if it were trying to get back into the sky, however after jumping off the building trying to jump into the sky, it fell to the ground below and wandered away whimpering. Finally, the Science Patrol cornered Seabozu in the middle of an open field away from society and opened fire upon the monster. After minutes of senseless violence and Seabozu being unrulingly attacked, it became obvious to the Science Patrol that Seabozu just wanted to go home to The Monster Graveyard.

The first attempt to send Seabozu home was to tie his hands around a massive rocket that would be sent to the Monster Graveyard. However the plan failed as Seabozu's weight and clumsiness caused the rocket to crash and burn on site. Ultraman showed up shortly afterwards and shockingly attacked the monster (possibly in hopes of knocking it out so he fly it home easier,) but Ultraman's color timer was running out and so he had to abandon Seabozu in mid-flight. Finally, a special rocket was designed for him. Ultraman met Seabozu again and ordered the monster to hold onto the rocket to take him home, but the monster's fear and stubbornness kept him from listening, provoking Ultraman at times to attack him into following his order. Finally after he grabbed onto the rocket. He was fired back to the Monster Graveyard where he could live the rest of his days in happiness.


  • In the special, Ukulele Ultraman, Seabozu is one of the monsters that celebrates, along with Alien Baltan.

  • Seabozu's name comes from the Japanese Yokai Umibozu (translated as "Sea Monk"), with the word "Umi" translated into English, "Sea".
  • In several stage shows, Seabozu is a peaceful monster and goes out of his way to help the Ultramen.
  • In one particular stage show, Seabozu makes friends with Ultraman Boy who is training with Ultraman Tiga and Ultraman. Seabozu shows his brave side by charging into battle with Alien Mefilas and his alien alliance.

Ultra FightEdit


Seabozu in Ultra Fight

This Monster reappeared in Ultra Fight.

In episode 143, Seabozu met up with Alien Icarus on the mountains and planned on being friendly with each other, but when Seabozu suddenly socked him on the head, Icarus got back up and grabbed the monster by his legs, and started to beat him up until the monster got back up and barely held his own against the alien. When Ultraseven shows up and tricked the two monsters into crashing into each other, they decided to work together to fight the Ultra and they were doing a pretty good job at the task at hand. They even saved each other when one of them was getting pummeled by Seven. However, just when they had Seven right where they wanted him, Seabozu suddenly threw Icarus to the ground again, which resulted in the two of them fighting each other once more. Ultraseven then decided that the fight was pointless, so he left and let the two of them duke it out, with Icarus once again winning.


  • In this series, Seabozu used Magular's roar.

Takeshi's CastleEdit

Seabozu appears in the Japanese variety show, Takeshi's Castle in the special "Monster" episode. He participates in the game "Boulder Dash" in which he fails in. In the U.S. variation of the show known as "MXC," he is called "The Closet Monster." Unusually, his costume in this appearance has a longer tail than his original appearance.

M78 Love and PeaceEdit

In the OVA special, M78 Love and Peace, Seabozu crash lands on ChibiM78 and was considered a threat by Ultraman, Yulian, Seven and Zearth, until he burst into tears. To cheer him up, Ultras, Seijins, Robots, and Kaiju alike joined forces to cheer up the sad monster. Eventually, a rocket comes to rescue Seabozu, but he decides to stay on ChibiM78 instead, and is shrunk down to the same height as all the others.
