The Avengers team. Steve, bucky, Tony, Natasha, Wanda, Peter, Bruce, Rodney, Maria, fury and... Y/N, plus Y/N's night fury. Yes, a dragon (from how to train your dragon, hehe~)

The team have no clue about Y/N's past, nor how the hell she got a dragon. Y/N has a bad past, abusive parents, hydra for ten years and red room for five. Y/N found her night fury, a boy named 'toothless', at hydra and just kept him.

The team starts asking questions.
