The Avengers have been through a lot together, thick and thin. Battles, fights, wins and losses. But then a new arrival comes to town. Her name is Jamie Adams. She's known in her town as the Demon. A half dragon girl with the power of dark magic that can take control of anyone from the inside, and turn them evil. She's now a threat to the Avengers, except for one. Peter Parker sees the good in everyone, even Jamie. But it takes more than an introduction to show Jamie that she doesn't have to be this way, and the Avengers that she can change. But what happens when she's not the only threat to New York that arrived when she showed up? She'll have to make her decision. Stay a demon or do what's right.
