avenger beast tame

so basically you read the name now story: you have a gift to speak to animals so when you fight with the avengers you either turn into an animal if you have the energy or you call out to animal by talking it's language and what I meant by enough energy well basically you have a health problem let's call it nonenergyopsisosis and basically your brain doesn't have full control over your legs so your basically in a wheel chair most of the time unless you shapeshift but shapeshifting is really painful for you and uses a lot of your energy and one time you didn't have enough energy to shapeshift back into a human for a month, so you don't really shapeshift that much unless you really have to and you don't go on many missions mainly because none of the avengers like you, the only one that likes you is tony, because he is your brother and he invited you to be part of the team but you don't have the best past with him becusse the only reason you have your powers is just because Tony experimented on you trying to make you be able to move your legs again but he didn't fail I guess cause you know in ur animal form (which is every animal in the world) you are able to move your legs fully and have no problems with them
