okay super simplified version thats a mashed up thing based on comic i mentioned and what I'm thinking
-Born to some rich jerks who are horrified at the wings
-Rich jerks reject him and have him raised and live isolated from them
-Rich jerks give up custody to Xavier's institute when he turned 10 (not specified of his age in the thing I'm reading about it)
-Angel (Warren) is then raised there 
-flash forward to 19 and he is requested for avengers academy 

I would add more to it but yea super simplified version
