Mask Rock (マスクロック) is one of the Rock People from Cronos.

He is 1.9m tall, weighs 1.03 tons and through his Cristobalite composition has a hardness of 9. Mask Rock thinks he's Batman, and lives on a mountain with his diminutive ward Magna Rock, going on about his mysterious past and martial arts skills to any unfortunate passing stranger. His Impulsar can become more powerful the more Mask Rock concentrates, which means he's shooting at the bad guys with his brain.

Rock Robo[edit | edit source]

  • Mask Rock (Rock Robo, 1986)
    • ID number: MRR-4
    • Accessories: Impulsar
Mask Rock was one of the Rock Robo in the Machine Robo:Revenge of Cronos toyline, and coverts from robot to Cristobalite rock in 4 steps. Mask Rock has good articulation at the shoulders, elbows, hips and knees, while his Impulsar clips to two holes on the robot's right forearm.
  • The same figure was issued as Marbles in Rock Lords by Tonka, with a modified colour scheme - the Japanese version has darker green robot parts as well as a painted mask on the face, presumably to try to break up that awful head cast. It is unclear which version of the figure was released first.

Notes[edit | edit source]

  • Mask Rock's face design and personality in Machine Robo: Revenge of Cronos are possibly a reference to Batman.
