Kid Omega (real name: Quentin Quire) was a former pupil of Xavier and a youth who had promising potential, at least in the eyes of Xavier, yet he would become a traitor and formed his own "Omega Gang" with the intent of brutally assaulting and even killing any non-mutants they came across - he is also an Omega-Level mutant, meaning that he is capable of surviving even after physical death: which he has apparently done several times.
