Rock Lord Marbles.jpg

Marbles is a Rock Lord from the planet Quartex. He is on the side of good and is second in command of Boulder's forces. Marbles is highly intelligent. He is also slightly clairvoyant, something he calls future sight, and can sometimes sense that something is wrong or that something is about to happen, although he does not know exactly what. This tells his fellow Rock Lords when to be on guard for the unexpected. He is also said to be able to create illusions in the minds of his enemies.

Marbles was part of Boulder's good Rock Lord army. He was present when Boulder and his forces planned to trap Magmar and his evil Rock Lords in a canyon, a plan which was interrupted by the arrival of the Renegades. Marbles retreated with Boulder's forces and was present when Nuggit brought Leader-1 and his Guardians to meet Boulder. Teaming up with the Guardians he took part in the later battle between the combined forces of the good Rock Lords and the Guardians, against the evil Rock Lords and the Renegades. Following the defeat of Magmar, and the Renegades' departure from Quartex, he wished the Guardians well and stated his belief that they would meet again.Battle of the Rock Lords

Rock Lords mini-comics[edit]


Boulder tired of the threat Magmar posed to Quartex and led his troops out to attack Stonehead, especially after Marbles had a vision that the Evil Rock Lords's power was growing. However they were ambushed by Magmar, who froze them in their rock forms with his new Cryon Ray. Only Nuggit - scouting ahead and clearly doing a bang-up job of it - escaped, following the Evil Rock Lords back to their base, where the Good Rock Lords were imprisoned in a cage. He was able to free them, allowing Boulder and his men to get free. Magmar again attempted to use the Cryon Ray but Nuggit had disabled it, so Boulder shot the whole group of Evil Rock Lords over with his Power Sword. Powerful Living Rocks Face a Deadly New Peril Boulder, Marbles and Nuggit headed to the Crystal Palace to find that Magmar, Spearhead and Saberstone had stolen Flamestone's new nuclo-crystal. They were unable to prevent the Evil Rock Lords leaving with their prize - or so they thought, Sunstone having switched it with an illusory version. There's Ssomething Flashing over There

GoBots Magazine[edit]

Along with Boulder, Granite, Crackpot and Pulver-Eyes, Marbles was cornered on a cliff over the Lava River by Magmar's Evil Rock Lords. Thankfully Nuggit arrived with the Rockasaurs, giving his friends an opening to fight back. Update from Quartex

Go-Bots comic[edit]


Marbles was one of the Go-Lems on the forgotten planet Earth at the centre of Gobotron, a group led by Boulder who believed themselves to be built by gods and born from the Earth itself. The group mainly meditated to achieve a state of mind they called the Quartex. However, when their meditations were disturbed by the Renegades and Zod the group aided the Guardians by opening up a chasm that swallowed up both Cy-Kill and Zod, giving an opening for the Go-Bots to finally destroy the monster.

Rock Lords[edit]

  • Marbles (Rock Lords, 1986)
    • Good Rock Warrior
    • Rock Type: "Marble: Hard, shiny rock reflecting his seriousness and high intelligence."
    • Accessories: Scanner/Laser
Marbles was released in the second series of Rock Lords by Tonka and converts from robot to marble rock. The figure was released in Japan as Mask Rock, one of the Rock Robo in the Machine Robo:Revenge of Cronos toyline, with a different colour scheme - the Western version had lighter green and simpler face, which sadly means you can see more of it; it is unclear which was the original release. Marbles has good articulation at the shoulders, elbows, hips and knees, while his Scanner/Laser clips to two holes on the robot's right forearm.

First prototype
Second prototype
  • The initial prototype version of Marbles featured a completely different head, much closer to that used on his character model. The first version was initially named "Granite" after Boulder became Boulder and had brown limbs; the name was later given to Granite instead.
  • A second prototype added the green parts to the same casting. Why they eventually went with the fuck-ugly version instead is unknown.
