Zeppelin (A avengers x supernatural crossover )

Just a warning this story doesn't not really have a plot line just something I had an idea for (also ships stony/superfamily comment other ships u would like to see, and nobody is dead in this story)

Zeppelin, that's what the Winchester's and bobby decided to call her after they found her half dead on Bobby's door step only being able to remember Led Zeppelin songs. Her parents Steve Rogers and tony stark lost her after she was taken by hydra at the age of three. There she was trained to be the next winter soldier, even got a metal arm, but at the age of 14 she escaped end ended up on bobby singers door step.
