Giradorus (ギラドラス Giradorasu), sometimes spelled Gira Dorus[1], was a Kaiju from the TV series, Ultraseven. Giradorus appeared in episodes 20.

Subtitle: Core Monster (核怪獣 Kaku Kaijū)



A Bioweapon created by Alien Shaplay to help him in his search for the substance that made up the core of the Earth, Giradorus searched underground while Shaplay disguised himself as the Seismologist's assistant.

After Shaplay was killed by the UG, Shaplay ordered his monster to kill the other members. Giradorus arose from the surface and began to rampage with his additional weather-controlling powers until Dan transformed into Ultraseven, saving the other members underground and bringing them to the surface. Because of Giradorus's weather manipulating tusks Ultraseven found it difficult to battle him, but the hero continued to fight. After escaping a tackle Ultraseven used the Eye Slugger to decapitate Giradorus, spilling the pieces of the Earth's core from his neck.


  • Giradorus's body structure makes him the only "quadrupedal" monster that is constantly kneeling.
  • Giradorus is one of the monsters/aliens seen in one of the stock footages of Seven's past battles in episode 48.
  • Although not physically seen in the movie, Giradorus is one of the monsters that makes up Belyudra's right horn in Mega Monster Battle: Ultra Galaxy Legends The Movie.
  • Marmit made a figure of Giradorus.
  • His roar is a copied Telesdon's roar during his fight with Ultraseven.
  • Giradorus is one of the only villains in Ultraseven to have the same name as it did in the original show when referred to in the TNT Ultraseven Dub.

A new version of Giradorus known as Albino Giradorus appeared in the novel. Albino Giradorus was under the control of an Alien Shaplay.

Ultraman Mebius appeared to fight it, and after a short fight, decapitated the monster, foiling Shaplay's plans as well.
