The Chemical Plant, typically referred to as Chemical Plant Zone, is a location that originates from the Sonic the Hedgehog franchise, making its debut in Sonic the Hedgehog 2 as the game's second stage, succeeding Emerald Hill Zone. Alongside Green Hill Zone and Seaside Hill, the Chemical Plant is one of the most reoccurring and well-known locations within the entire Sonic franchise.
An industrial cityscape filled with futuristic skyscrapers, warehouses and twisting chemical pipes, the Chemical Plant is located on West Side Island, the birth home of Miles "Tails" Prower. Its most defining feature is the various chemical-producing facilities populating the area, which produce several different types of hazardous chemicals, most notoriously the toxic Mega Mack - pink liquid that highly resembles water. The Chemical Plant is owned by none-other than Dr. Eggman himself, with the facilities used to supply many of the doctor's nefarious schemes. The zone's reappearance in Sonic Mania features cyan and green variants of Mega Mack, that function as bouncy platforms, and a Puyo Puyo-themed boss fight against Dr. Eggman.
In M.U.G.E.N, Chemical Plant Zone has been made twice: once by MabsKMK and once by GroxDJ. Both versions utilize graphics ripped from Sonic the Hedgehog 2, although neither bear any resemblance to the two act's layouts. MabsKMK's version received an edit by Yoshian12 to make it compatible with M.U.G.E.N 1.1's new stage features, although MabsKMK eventually made his own 1.1 version.
MabsKMK's Chemical Plant Zone uses sprites taken from Sonic the Hedgehog 2, though the ChemicalPlant2 and ChemicalPlant4 definition files recolour the background buildings to match their appearance in the Sonic - The Lost Land 2 ROM hack, while also adding a fog effect that partially obscures the lower parts of certain background objects. Sonic and Tails make respective background appearances running eastwards atop the raised platform and being transported westwards via a high-speed warp tube, while Dr. Eggman mostly follows the camera's horizontal movements in his Water Eggman, but briefly disappears below the stage floor when the Water Eggman's tank of Mega Mack empties its contents onto his head, only to re-emerge some time later with a refilled tank and Dr. Eggman's head having been cleaned off. The stage is notable for its incredible width, which makes getting from one side of the stage to the other quite a long and arduous trek for all but the fastest combatants or those without an otherwise high-speed method of travel; on the other hand, the stage's camera doesn't have quite as much work to do when scrolling vertically as is does when scrolling horizontally, though there's still plenty of head room for characters with Super Jumps to use them without needing to worry about going offscreen.

GroxDJ's version of Chemical Plant Zone uses sprites that are mainly ripped from the first three Sonic games, with the majority of the assets having been taken from Sonic the Hedgehog 2, though the background has elements from the original Sonic the Hedgehog (Scrap Brain Zone and Star Light Zone) and the capsule in the stage's centre originates from Sonic the Hedgehog 3, leaving the stage's floor as the only element which wasn't taken from any of the aforementioned games, instead being a modification of the floor from Original Zero's stage in The King of Fighters 2002: Unlimited Match; all of the sprites ripped from one of the aforementioned games have subsequently been sharpened during the stage's creation process, ironically resulting in them having noticeable blurring, particularly those closer to the foreground. Made using the Automatic Stage Creation Tool, the stage lacks any animating elements and doesn't allow the camera to cover much vertical distance, though it just about scrolls up enough to keep the greater portion of character using a Super Jump on screen.
