you were 5 when HYDRA kidnapped you and started doing experiments on you. You were 12 when you finally succeed on escaping and even if you hate admitting it, it was thanks to those experiments that gave you powers that you escaped. Which powers they gave you? Basically the same as Spiderman. As you ran away you begged an old lady to host you and she accepted even if confused. And now that you're 17 you live with her. As you grow up you understand that your power can be used to do something good for the people so that's what you do. Save the people and city from criminals. NOBODY knows about your identity. But of course someone else noticed you. In fact it didn't take too much for Nick Fury to notice you and tell the Avengers to get you in their Tower. But every time they tried to approach you, you always run away scared that they wanted to imprison you as you were "stealing their job" Until one day. As you returned home from school you noticed a very rich car outside your house and as you enter your old lady, Mary, greet you immediately with a smile "Come, come, there's some people that want to talk with you" she says with a smile as she brings you to the living room. The fact is that you expected everyone but the Avengers there sitting on the couch
