Occupation: Sentient Transylvanian hill bent on world domination
History: When a race of intergalactic spores fell to Earth, the planet's gravity pulled them into its molten core. They eventually developed mental powers such as telekineis, which they used to create earthquakes (so that's where earthquakes come from)! One of these earthquakes accidentally sent a spore-being named Spragg to the Earth's surface near Transylvania, where he immediately enslaved an entire village to build a power-enhancing dynamo around him.
Meanwhile, a vacationing geologist named Dr. Bob Robertson realized his metal miner's helmet made him immune to Spragg's mental control...which allowed him to secretly (and by himself!) convert Spragg's dynamo into a giant rocket platform. Believing he was mentally activating his power dynamo, Spragg inadvertently rocketed himself into space, only to return several years later to battle the She-Hulk (and an elderly Bob Robertson).
Powers and Abilities: Spragg could animate and control the rock around him, which could be used to create multiple duplicates of himself (including a humanoid form), rock towers, and vast holes in the ground. Spragg also possesses telepathic powers such as mass-hypnosis and mind control. As demonstrated by Robertson's helmet, a major weakness of Spragg's was steel.
