You were a lab experiment, kidnapped when you were just born, still in the hospital. You’ve spend your entire life in the lab, with the cruel scientists. One day this group saved you and the other experiments, now most of the kids/young adults have gone home to their families who accept the animalistic/monster like abilities and features given to them by the scientists. Although yours didn’t want you back, they’d moved on, already had a family. Now you stay with the group at their huge house as they all live together. The scientists that were at the lab have all been arrested.
