X-MEN: Generation X
The Massachusetts Academy was one of the oldest and most respected college preparatory schools in the United States. Run by a board of trustees, a young mutant named Emma Frost became chairperson of the board and ran the school. Frost served as the academy’s headmistress and spent a great deal of her time there. After Frost staged a coup that gave her and Sebastian Shaw control of the Council of the Chosen, which they renamed the Inner Circle, the Massachusetts Academy also had a long-standing alliance with the Hellfire Club. In addition to a large student body, Frost recruited young superhuman mutants and trained them in the use of their powers at her school, so that they might use those powers on the Inner Circle’s behalf. Most of these mutant students were members of a team called the Hellions.
While attempting a truce with the X-Men at the Hellfire Club, the Hellions, X-Men, and Emma were attacked by Sentinels, sent by Trevor Fitzroy, and Emma was sent into a deep coma. Emma was cared for at the Xavier’s School and had ironically left her school to Professor Charles Xavier, in her will. Upon emerging from her coma, Emma learned that the majority of the Hellions had died in the attack from Fitzroy. After the death of the Hellions, Frost temporarily retired from teaching and withdrew from the Hellfire Club. Reexamining her teaching methods, Frost would align herself with Professor Xavier and the Massachusetts Academy reopened as the new site of Xavier’s School for Gifted Youngsters. Together with co-headmaster Sean Cassidy (Banshee), Frost would train a new class of young mutants, Generation X.
After a period of operating as a school exclusively for the training of mutants, the Massachusetts Academy would resume functioning as a broader educational facility. To the surviving Hellions, however, the truce with the X-Men was seen as both a weakness and the cause for their destruction. Citing betrayal as their battle cry, the Hellions have begun a campaign to destroy Generation X.
