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.

Seabozu in Ultra Fight

This Monster reappeared in Ultra Fight.

  • Seabozu made his first appearance on the show in episode 114, where he confronted Alien Icarus and took him on in a wrestling match and after a long, evenly matched fight, the monster came out on top.
  • In episode 122, Seabozu appeared to help Alien Icarus fight Ultraseven. Despite the two of them outnumbering the ultra, Seven pulled through and defeated Seabozu by judo throwing and chopping and punching his face before defeating Alien Icarus afterwards.
  • Seabozu reappeared in episode 124, where he went up against Keronia and defeated him with a punch to the face after easily overpowering him via grappling techniques. He then went up against Woo and managed to hold his against the monster, until Woo overpowered and ended up defeating Seabozu instead, turning things around.
  • Seabozu reappeared in episode 128, where he fought Eleking near the shore in a long, evenly-matched fight and Seabozu ended up losing.
  • In episode 134, Seabozu confronted Ultraseven alone and they duked it out with each other. The two of them even got into a pose-off with each other. In the end, despite Seabozu being a formidable opponent, the Ultra pulled through and knocked out the kaiju with a karate chop to the face.
  • Seabozu reappeared in episode 137 where he played soccer with a small boulder alongside Alien Icarus, which started out fun, but ended up getting violent with each other after Icarus kicked the boulder and it hit Seabozu on the head. While Seabozu held his own against Icarus, the former ended up losing to the latter when he knocked him down and then beat him to death.
  • In episode 139, Seabozu came across Woo for quite a while on even terms as they grappled with each other and both of them gained the upper hand at one point or another and Woo eventually became the winner after Seabozu collapsed from exhaustion.
  • Seabozu reappeared in episode 140, where he came across Eleking again and the two monsters were evenly matched once again. After the fight went on for quite a while, Seabozu tried to end the fight by holding onto Eleking to try one more attack, only for Eleking to knock Seabozu out with a karate chop to the head.
  • 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.
  • Seabozu reappeared in episode 146 where he snuck up on Ultraseven from behind as he was contemplating on life at the coast. Afterwards, the two of them fought each other on equal terms. The fight later attracted Eleking's attention and the skeletal monster was defeated by the new monster and he just laid there unconscious as the other monster turned his attention towards the Ultra.
  • In episode 149, Seabozu fought Ultraseven again alongside Alien Icarus and Eleking. and even though they outnumbered him yet again, Seven still held his own and held the upper hand against them. Soon afterwards, Eleking picked a fight with Seabozu and then with Icarus when Seven through him at them. Seven then decided to finish the fight and knocked them out one at a time with Seabozu being the first one knocked out by a punch to the head.


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