Ok so I don't know if anyone has ever seen this movie called Ninja Assassin. But in it this kid is forced to become an Assassin but rebels after his love is killed while trying to escape. Ok anyways the clan has like some kind of body control that can help heal wounds and can phase and travel through shadows. I'm thinking MC is forced into the hand at a young age of 5. Some kind of life or death mission his mutant powers awaken.Becomes expert maybe master Assassin at 14-17 and control but not mastery of powers. He is tasked with killing rebel scientist Sarah Kinney and young daughter laura as a job given to the hand from the Weapon X program. I think seeing Sarah Kinney try to protect laura breaks some of the brainwashing and rebels with them. They travel to Professor X's school to seek protection and boom!
