Subtitle: Hypnotism Magical-beast (催眠魔獣, Saimin Majū?)



A bizarre rock-like alien from space, Ragstone came to Earth for the life force of others. Over time Ragstone started to make a cult of sorts dedicated to bringing him food and even had a building made in his image. Once EYES discovered this strange cult and sent Shinobu to investigate only for Ragstone to nearly kill her. After EYES quarantined Ragstone's building from his followers, Shinobu work up under the alien's control and started to head toward him. Shortly after, Ragstone grew to his true form. When Ragstone amplified his powers to make many more worshipers, Musashi turned into Ultraman Cosmos. Once Cosmos went from Luna to Corona Mode, he stopped Ragstone from using his powers. The battle between Cosmos and Ragstone seemed to be even until the alien creature shrugged off the Naybuster Ray without even a scratch. After this, Cosmos went back into Luna Mode to use the Luna Shootless, restoring everyone's life force and forcing Ragstone to flee Earth in his saucer.

Ragstone MechalatorEdit


After failing to capture the baby Arados, the Alien Nowar launched Ragstone Mechalator to battle Team EYES. Ultraman Cosmos appeared and battled the cyborg monster but was quickly overpowered by the monster and flying saucer teamwork. Arados used the last of power to banish Ragstone Mechalator into another space and time and seemed to finally die from exhaustion. Cosmos furiously destroy the Alien Nowar spaceship and flew away.


  • Suit actor: Hiroshi Nagatomo.
  • Ragstone's roar is reused from the Ultraman Tiga monster, Golza.
  • In episode 43 of Ultraman Cosmos, the Alien Nowar mentioned that all monsters from their planet died due to the failure of their monster remodelling. Ragstone however came from the same planet and was remodelled on Earth but survived unlike the Earth monsters. It can be presumed that it fled from Planet Nowar sometime before the alien race remodelled all of their planet's kaiju.
  • Ragstone's overall design is a tribute to MSM-04 Acguy from Mobile Suit Gundam.
