Morlocks

Overview
The Morlocks are a group of Mutants who believe they are outcasts from society due to the mistreatment of Mutants. They live under the Bayville Sewer Systems in hiding only to come out and save fellow Mutants who are being mistreated. According to the X-Men they act like "Mutant Vigilantes" when they choose to take matters into their own hands.

Outcast
Callisto was mistreated from the moment who Mutant abilities showed themselves to her peers. She was beaten and battered causing blindness in her right eye and leaving her disfigured. She moved into the sewers to live peacefully and away from the evils of the world. She came out of the sewers here and there to scavenge for food and clothing. On a quiet night whilst scavenging she discovered another Mutant who's Mutation caused disfiguration. The Mutant was taunted by being called Ape due to his monkey-like physical deformity. She saw he was being treated the same way she once was and intervened. She beat up the group using her Mutant abilities in an attempt to rescue Ape. Callisto was successful and aided Ape by allowing him to live in the Sewers with her.

Every night Callisto and Ape went scavenging and looking for Mutants that were in trouble and being harmed by others. They continued rescuing more and more Mutants and before they knew it they created their own little community down in the sewer systems as well as a family.
