The Marble Zone boss, from Sonic the Hedgehog #226.

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, the Marble Zone boss consists of a modified Egg Mobile. It appeared as part of GENESIS arc, where it is piloted once by Dr. Eggman. When the doctor learned that Sonic had been foiling Snively's doings, he arrived in the Marble Zone to face Sonic himself in the modified Egg Mobile.

When Dr. Eggman started chasing Sonic, who kept balancing on pillars in the lava lake, he eventually came to a dead end. There, the doctor almost got him when a Buzzbomber, which had been reprogrammed by Rotor to help them, tried to attack him from behind. Though Eggman destroyed the Buzzbomber, it gave his enemy the chance to attack the Egg Mobile, causing it to get damaged by a pillar. The doctor then chose to escape, but blustered that once his master plan was being completed, all of them would suffer his wrath.

Sonic X (comic series)

In the Sonic X comics published by Archie Comics, the Marble Zone boss, piloted by a fake Dr. Eggman, was encountered by Sonic and Amy in the Marble Zone section of the virtual reality they were trapped in. As the fake doctor approached and attacked the duo, Sonic advised Amy to pick up some Rings for protection against attacks. After doing so, she took out the fake Eggman without restraint but fell into a pool of lava in the process. Thanks to the Rings, however, she was not burned and escaped from the pool with Sonic's help while Eggman fled from the scene.[1]
