The Mega Muck is a purple and toxic liquid with texture seemingly identical to that of water.
- Note: From the readers point of view, this picks up from where the Mega Muck's original timeline ended.
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.
