Mega Muck is a substance that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is a toxic liquid that flows through the Chemical Plant Zone.
The Mega Muck is a purple and toxic liquid with texture seemingly identical to that of water.
The Mega Muck resurfaced in the Skull Egg Zone after the launch of the second Genesis Wave. While searching for the Roboticized Masters, Sonic, Tails and Mega Man would cross a lake of Mega Muck.

Upon the formation of the Unified World, Mega Mack flooded a federal prison from Mega Man's World in the year 20XX when the Chemical Plant Zone fused with the prison. This was later undone when Xander Payne rewrote history so that the merging of the worlds never occurred.
