Geiger Rock

Geiger Rock (ガイガーロック) is one of the Rock People from Cronos, in the service of the Gyandlar and second-in-command to Devil Rock.

He is 2 metres tall, weighs 1.15 tons and has a hardness of 10, being made up of radioactive space rock. Geiger Rock is a tactical genius, but his ultimate plan is to overthrow Devil Rock and become leader of the Gyandlar Rocks. He is an expert inventor, devious spy and can drill himself down into the ground, while he can also emit lethal pulses of radiation from his body itself or via his Atomic Death Fork.

One Geiger Rock was Gelvar.

• Geiger Rock (1986)
  • ID number: MRGR-2
  • Accessories: Atomic Death Fork

Geiger Rock was one of the Rock Robo in the Machine Robo: Revenge of Cronos toyline, and coverts from robot to space rock in 4 steps. Geiger Rock has movement at the shoulders, elbows, hips and knees but sadly his arms can only move out parallel to his body, which means he can't raise his weapon.

• The same figure was issued as Tombstone in Rock Lords by Tonka, with a modified colour scheme - the Japanese version has red robot mode parts. It is unclear which version of the figure was released first.

Notes

• Geiger Rock's name appears to be a double pun, referring to both his radiation-based abilities and his head's resemblance to H.R. Giger's designs for the Alien franchise.
• The character makes weirdly few appearances in the cartoon compared to Devil Rock and Double Rock - if there are two Gyandlar Rocks required for a scene rather than 3, Geiger Rock is always the one that's missing.
