In fiction, mole people are stock characters who spend their lives underground, often posing a real or potential threat to those who live on the surface.[1]
In Marvel Comics, the Moloids or Mole People are inhabitants of Subterranea, a fictional cavernous realm far beneath the Earth's surface where various species of subterranean humanoids exist. Moloids usually serve as soldiers for the Mole Man, a human from the surface world who discovered Subterranea and subsequently became ruler of the Moloids. Mole Man is frequently an antagonist of the Fantastic Four.
