The Hellions was a team of adolescent mutants being trained in the use of their superhuman powers by Emma Frost, the White Queen of the Hellfire Club (see Hellfire Club, White Queen). The members of the Hellions all registered as students at the Massachusetts Academy, a private school located in Snow Valley in the Berkshire Mountains in Massachusetts. Frost was headmistress of the school and it was here that she secretly trained the Hellions in using their powers. It was Frost's intention that the Hellions, when fully trained, would serve the interests of the Hellfire Club's Inner Circle, which seeks to amass political and economic power through both legal and illegal means. However, the individual Hellions varied in their motivations, and not all of them leaned towards criminality. Most of the Hellions were killed on a mission and the Hellions ceased to exist. It has recently come to light that Gateway may have had something to do with their deaths (see Gateway).
