The Marble Zone is a location that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It was a Zone consisting mostly of trees, ruins, and magma deposits on Mobius that existed during Operation: Clean Sweep.
During the period when Dr. Eggman's Operation: Clean Sweep altered reality and reshaped Mobius, Sonic visited the Marble Zone with Sally, Antoine, and Boomer after freeing them from a capsule in Green Hill Zone. Sally lead the others to Marble Zone as part of a shortcut to Dr. Eggman's lair. Here they encountered Caterkillers, Bat Brains, and Buzzbombers before Dr. Eggman made an appearance to get revenge for Sonic beating his nephew Snively in Green Hill Zone. With the help of a reprogrammed Buzzbomber, Sonic managed to defeat Dr. Eggman, and Sally continued to lead the gang.
