Magma the Volcano God is a prehistoric lava entity that lives in a volcano and guards the Chaos Emerald of Life.
He does not allow anyone to have the Chaos Emerald unless they first make a sacrifice to him, which must be thrown into his lava. However, the lava is actually volcanic mud, so the sacrifice is not destroyed, but rather becomes messy, as it is what happened to Scratch and Grounder when Dr. Robotnik sacrificed them.
