Y/N is wanted by HYDRA for their unique and strong powers. Today, they had ultimately found y/n's hiding place and now y/n was on the run. While running through seemingly endless terrain of forest with HYDRA troops not far behind them they stumble into an unexpected group.
You are part of quadruplets and you each have a specific power each one has a different element. One has fire, one has water, one has air, one has earth. We were in human school one day and a bald man in a wheel chair named professor Charles Xavier. Comes into our classroom asking to see us in private to talk about us ant that he is there to talk about our powers that no one knee we had and he tells us that he has powers as well and that we should join his school for the gifted. I have the air element.
Y/n is one of the strongest x-man, s/he's a vampire, has to eat organs and drink blood to survive, but s/he's with the x-men, everyone trusts her/him. One day a student hits her/him with his power not on purpose, the power of the student makes the person he touches go back (with the mind) when the person had the half of the actual ages (example: a person is 50yrs old and with that power the mind of the person goes to the past when he was 25 years old even if the body is still the same). Y/n is really old, and s/he became "good" only since 10 years, s/he's also very old, s/he's probably about 1000 years old, her/his mind will be of when s/he was 500 years old for an entire day...
