The Planet Gamma (プラネット眼魔, Puranetto Ganma, lit. "Planet Eye Devil") is a Gamma which achieved evolution through an Astronaut helmet.


  • Object infusion: Astronaut helmet
  • Eyecon Target: None
  • Destroyed by: Kamen Rider Ghost Ryoma Damashii's Mega Omega Flash



Gamma Eyecon

Planet Gamma's Eyecon, along with an Astronaut helmet

The Gamma are created from the Gamma Eyecons (ガンマアイコン, Ganma Aikon), and one was merged with an Astronaut helmet to create the Planet Gamma.

Gamma Assault

The Gamma Assault (眼魔アサルト, Ganma Asaruto, lit. "Eye Devil Assaut") are Ganma born from the Gamma Eyecon. They first appear in Primal Body (素体, Moto-tai). Gamma Assaults do not possess unique abilities of their own, but can gain powers of their own through being infused with an object around them.

Powers and Abilities
A Gamma's primary ability is to turn themselves invisible and intangible to the public. Those whom wielded an Eyecon are capable of witnessing them.
Gamma can infuse themselves with ordinary objects, converting said object into a Parka Ghost, to achieve a unique evolved form. Should the Gamma be defeated, the object will be restored to its original form as the Gamma is destroyed.

Planet Gamma

Through bonding with a yet to be known object, the originally generic Gamma evolved into the Empowered Gamma (強化眼魔, Kyōka Ganma, lit."Empowered Eye Devil") known as Planet.

Powers and Abilities
A Gamma's primary ability is to turn themselves invisible and intangible to the public. Those whom wielded an Eyecon are capable of witnessing them.
Eyecon/Parka Infusion
Gamma Assaults can infuse themselves with Ghost Eyecons or at the very least, their Parka Ghosts to become Giant Ganma.
Energy Attack
Planet Gamma is able to attack his enemy by his planet-like energy.
Life Force Extraction
By hijacking communication devices such as satellites or giant parabolic antennae, Planet Gamma can rob life forces from any nearby victims.
Rocket Propulsion
Planet Gamma is able to leave the Earth atmosphere by unleashing booster-like features underneath his legs.


Planet Eyecon

Sounds for a hypothetical Planet Gamma Eyecon are programmed into the Proto Mega Ulorder.

Behind the Scenes


Planet Gamma's suit actor is Eitoku (永徳), who is also the suit actor for Kamen Rider Necrom, and is best known as the suit actor for most secondary Riders up to Baron.

Concept Art

Planet Gamma was designed by Kazuhiko Shimamoto (島本 和彦, Shimamoto Kazuhiko).


  • To further relate his connection to Yuri Gagarin, Planet Gamma's head color is blue, harkening Gagarin's famous word after venturing in outer space, "The Earth is blue...".
