Well here's the basic cast and their backstory for my storyline. It would be 2-3 movies long.
The aftermath of X-3 left Storm as headmistress of Xaviers School and leader of the X-Men, Logan became the gym professor, while Beast handled mutant affairs in the UN, and the institute gained a new student, Angel. While Iceman, Colossus, and Shadowcat became fulltime members of the X-Men, Rogue stayed as a student even though she took the cure. There still is some of the love triangle between Bobby, Kitty, and Rogue. Though Nightcrawler left because he couldnt live the life as an X-Man, he came back and became a teacher at the school. Also newly hired teachers are the depowered Magneto, depowered Mystique, Sean Cassidy (former X-Man Banshee) and Dr. Cecilia Reyes.
Though there already is an X-Men team, there are also X-Men in training for the future. The trainees are Angel, Rictor, Siryn, Jubilee, Dust, Sunspot, the Stepford Cuckoos, Pete Wisdom, and Julian Keller. The rest of the student body just go to the school so they dont have to put up with intolerance in normal school. Angel hangs out mostly with Rogue, Bobby, Kitty, Piotr and Storms nephew Spyke. Rictor, Siryn, Sunspot, and Pete Wisdom mostly hang with Cypher, Cannonball, Moonstar, Karma, and Chamber. Jubilee and Julian are good friends, and their clique include Mercury, Elixir, and Wallflower. The Stepford Cuckoos and Dust usually keep to their selves. The rest of the students are Quill, Artie, Leech, Jones, Quentin Quire, Franklin Richards, and Angel Salvatore.
Havok also comes to the school to meet with his brother, Cyclops. Storm apologizes for not contacting him sooner and explains about Cyclops being dead, but no body was ever found. She then invites him to stay at the mansion. Havok not only gets pissed with Storm but he berates her, afterwards leaving in search of his brother. On his way, some of the students help him and two go with him.
After Magneto abandoned who were left on Alcatraz, Pyro survived and started his own Brotherhood, consisting of fellow survivors Juggernaut and Psylocke. His new Brotherhood consist of Gambit, Stacy X, Quicksilver, Scarlet Witch, Polaris, Avalanche, and Toad makes a return. They still believe in Magnetos view of homo-superior.
After the Liberty Island incident, the Alkali Lake incident, and the Alcatraz incident, the U.S. Governments Bolivar Trask was given approval by the President to continue with Project Wideawake as an alternate answer for extreme cases that may come in the future. Trask is aided by Special Assistant Valerie Cooper with Project Wideawake. They have been getting sponsoring from the high class Hellfire Club.
The Hellfire Club has been part of the high class of New York for quite some time now. After hearing about the outing of the X-Men, they were concerned that they would get in the way of the Hellfire Clubs growing dominance. Any high class yuppie or yuppette can be a member but there is a secret Inner Circle where the Hellfire Clubs true ambition is plotted. The current leaders of the Hellfire Club (including Inner Circle) are Sebastian Shaw and Emma Frost. Other Inner Circle members are Emmanuel DaCosta, Harry Leland, Donald Pierce, Jason Wyngarde, Friedrich Von Roehm, and Shinobi Shaw. They also have Tessa as a servant.
Some people that the Hellfire Club has their eye on is the world known singer Alison Blaire and the famous Australian surfer Davis Cameron. Theyre only in the Hellfire Clubs interest for their star power and their mutant powers and they are hoping to recruit them into their Hellions. At the moment their Hellions consist of Beef, Bevatron, Empath, Jetstream, Roulette, Tarot, and Firestar.
