We Live to Fight! {Young Justice & Avengers Crossover}

My name is Amber. No last name? Yes, but I'm not going to tell you. I might look normal girl to everyone. But I'm not. I accidentally did something that changed the whole world forever. My mother works for S.H.I.E.L.D. and my dad? I have no idea. He left my mother when I was little. And he never came back so he kinda doesn't care about me so yeah... but to the story. My mother died on a mission. I think. I was little and I wasn't paying attention. Don't judge! Anyway back to the thing I did. I might have-Wait I'm not going to tell! It would just ruin the whole story. All you need to know is that there are more heroes out there then the Avengers. Like the Justice League and their annoying sidekicks.
