S-Gray Mutant



The S-Gray Mutants are any creatures that were mutated by exposure to the genetic muck of Agent Bishop's S-Gray Aliens.

History
After the S-Grays were destroyed, their genetic residue was flushed into the New York City sewers. However, the substance proved to be highly mutagenic and transformed anyone and anything who came in contact with it, triggering a mutant outbreak.
