Necra

Necra is the daughter of Hela the Goddess of Death. When Necra was born she was given up to a Human family fearing that if she was to grow up in Hel it would corrupt her and make her a very deadly target, As she grew she would question her weird features like her green hair and her mysterious presence and also her weird birthmark. It was unknown that she had powers until one day when she was walking home and a group of thugs try to rob her and rape her and she push them away with a small blast of green energy and ran away scared. Days after she tried to access her powers and one day she noticed that a green energy  like mist was swirling around her fingers so she started to focus on that night to access her powers and learn how to use them by carrying little metal pieces and using her powers to control them. Unknowingly she was being watched by multiple sources. She started to wonder how she got her powers so she started to ask her parents and that when she found out that she was adopted and after that she became very upset causing her powers to manifest again and everything that was sharp started to levitate and her adopted parents tried calming her down but Necra voice became deeper and and everything that was sharp flew to her parents knocking them back and killing them. When she calmed down she saw everything and she ran away in fear and she ended being recruited by Professor X and taken to the school of mutants where she was trained about her powers. After seeing her powers and how unique they look Professor X couldn't get a good read on on her to tell if she was real mutant or not ,he could tell that she has very powerful potential and that her powers are only beginning to grow and that she would develop more powers and he notice something dark in her but he couldn't explore it more.
