Sewer mutants

Species: Mutated Human  Planet of Origin: Earth  First Appearance: "I Second That Emotion" (2ACV01) 

Description
Below the city of New New York, in the mirky, polluted sewers, live a race of hideous mutants. Appearances aside, they're mostly decent people, if a little odd. It is unknown how long they have dwelled in the sewers, but it has been long enough for them to build a city and a semblance of civilization. They have their own library (consisting of "Nothing but used porno and Ayn Rand,") and their own religion, which involves worshiping an unexploded nuclear bomb, but according to Vyolet "nobody's that observant. It's mainly a Christmas and Easter thing." Mutants seem to be impervious to many toxins and radiation, at least they can't be mutated again once they are mutated. There are probably a few hundred of them, each with his/her very own unique mutation. Extra or missing appendages or organs mostly work. The Mutants have their own civil organzations such as doctors, commerce, and schools.
