Seagra (シーグラ Shīgura) were four dinosaur-like monsters that appeared in the anime The☆Ultraman.
Subtitle: Freezing Monster (冷凍怪獣 Reitō Kaijū)
Shortly after the Scientific Defense Guard had been assembled, ice burgs from the Antarctic region began to melt with one of them containing ancient monsters known as the Seagras. An ice burg containing a lone Seagra was intercepted by the Scientific Defense Guard only for it to hatch from its icy tomb within minutes. After a laser barrier failed to contain the monster, Seagra made his way toward an unsuspecting harbor before completely freezing it and the city it was in, completely turning it into an icy tundra. The Scientific Defense Guard attempted to fight off using their fighters only for three more members of his species to emerge from the ice to assist it.
Once Choichiro's fighter crashed he used the Beam Flasher for the first time to transform into Ultraman Joneus. As the Scientific Defense Guard was caught by surprised, Joneus took the monsters on one by one and shortly into the fight managed to cause to of them to freeze each other. The other two Seagras teamed up on him with his color timer beginning to turn red, forcing him to use his Planium Ray on both of them, knocking them out and returning the monster to their frozen confinements.
- Red King was originally supposed to appear in Seagra's place, but this was changed during production.
- The reason that there's four Seagra is likely to show-off what could be done with The☆Ultraman in animation.
- According to materials released after their debut, the Scientific Defense Guard speculate the Seagra species to have originally been normal dinosaurs until being mutated through an unknown source.
- In Imura Junji's manga adaptation, Joneus had come to Earth in the long-forgotten past to study humans. He ended up fighting several attacking Seagra, two of which fled and later confronted him in modern-day.
- Seagra's design was reused and reworked for an unnamed trophy monster briefly seen in episode 42.
