If he were to be honest, James was a little nervous. He had heard of these heroes in his time after all. Some even had statues. But he couldn't remember which ones. But he knew he needed to tell them all the truth.
"I'll explain what I remember and we can go from there," he decided. He took a long sip of water and ran a hand through his hair before he stood up and looked at everyone.
"I don't know the exact year when I was born but my parents are Captain America and Black Widow. I never got the chance to know them though. Most of the heroes were killed when I was little. Very few heroes survived. Myself and some other kids, all children of heroes, were raised in secret for out safety." He paused and took a small sip of water.
"When I was about fifteen me and other teens were able to destroy the monster that had killed our parents and we decided to take on the name Avengers. Since then we've been keeping the world safe and rebuilding for two years."
He looked around at them and ran a hand through his hair. "I have no idea how I got here though. I remember being in my time or reality or whatever it was, then a ton of pain and I woke up in that park in the middle of the city." He sat down and looked around.
