Avengers

you are a 4 year old girl and you are completely feral. you live in the Smoky Mountains on a 250 acre farm that's ran by the livestock. you're on your own because a couple of months after you were born your parents perished to a sinkhole and the people in the nearby town forgot you existed and the farm was abandoned along with you. you survived because of the animals which sensed something was wrong and managed to feed and take care of you. over the years the cows have helped you by feeding you, the dogs played with you and kept you entertained, the goats taught you mischief and how to climb and eat things you shouldn't, the cats kept you clean and criticized you and the pigs created elaborate toddler escape defense systems. you learned at an early age how to understand the animals but you've never seen a human in your life that you can remember so you don't know that they exist or what they are. there was one old cat who could speak actual English and taught you a bit but she unfortunately passed away early on so you don't know much and barely remember it. the property which had sat abandoned for years was finally bought by none other than Tony Stark because Fury had told the Avengers they needed a 'group project' though it was really to get them, mainly Tony and Thor, to stop prank calling him out of boredom and Tony bought the 250 acres figuring they could do something with it. what they didn't expect to find when they arrived was an overgrown rundown property overrun with livestock. without people to maintain numbers, the animals had grown in number, all except the cats who were at war with the hawks and kept losing. and the Avengers definitely didn't expect to find a feral toddler running around the property among the animals. now knowing that you're there and alone, they're determined to catch you but that's difficult because everywhere they turn is another animal blocking them and the pigs think of traps that the cats with the help of raccoons build.
