Ultraman Dyna


After losing connection with a bacteria breeding/landing pod on Venus, Super GUTS travels to Venus in hopes of recovering the lost specimens and data of the breeding program. However, unbeknownst to them, the bacteria was mutated by Sphire into Graikis and sent to prowl the Venus atmosphere. As the Kolakerf NF-3000 descended, it became under fire by Graikis and unable to strike back due to all missiles being destroyed by the atmosphere before even reaching their target. Graikis moved through the Venus atmosphere like a fish in water, forcing S-GUTS to abandon all of their missiles to create a smokescreen and escape. Asuka boldly rushes off in the Guts Eagle Alpha Superior, followed by Ryo and Kariya. On Venus, they discover the destroyed landing pod and Sphire, who has transformed into a spaceship the protects it from harm. Graikis shows up and downs Asuka's jet, causing Ultraman Dyna to appear. Dyna and Graikis began to fight, but Dyna was easily overpowered by the combined force of Sphire's lazer beams and Graikis's fireballs and natural strength. Dyna then transformed into Miracle-Type, using clever teleportation abilities to confuse Graikis. However, Dyna tried to fire his Revolume Ray, but failed and was being slowly forced by Graikis into a pool of Lava. With a sudden burst of courage, Ryo and Kariya was able to destroy the Sphire spaceship and gave Dyna an opening. Dyna then transformed back into Flash-Type, and executed a chop directly to Graikis's forehead, destroying the Sphire within and causing Graikis to return to his bacteria form, flowing from the sky like snow.


  • Suit actor: Koji Mimura
  • Many fans questioned Dyna's decision to change into Miracle-Type instead of Strong-Type in order to compensate for Graikis's superior strength. However, the truth is that Dyna transformed into Miracle-Type in order to match Graikis's speed, which was higher than his due to the atmosphere and higher gravity slowing Dyna down. Also, the teleportation abilities also gave Dyna the edge, making the choice reasonable.
  • This episode was featured in episode 146 of New Ultraman Retsuden, "Type Change Hero! Tiga and the Warriors of Light".

Powers and Abilities

  • Flight: Graikis can fly at high speeds.
  • Fireball: Graikis can launch fireballs from it's mouth.
  • Super Strength: Grakis is a very strong monster, able to move swiftly in Venus' now dense atmosphere and also easily over power Flash and Miracle type Dyna
  • Sphere: As a being modified/created by the Sphere, Grakis had one in his head.
    • Face Armor: Graikis's face is somehow able to break attacks like the Ultra-Slash. This is most likely due to having a Sphere integrated into his head as when targeted at other parts of his body by other energy attacks, the monster would dodge..
    • Recharging: When defeated, Grakis would be recharged by a beam from another Sphere nearby.


If the Sphire piece on it's forehead is damaged Graikis will return to normal.
