Yn x avengers

You are yn stark, you have calico hair ( all types of colours like ginger, brown, black and etc. ) You are also a skilled and trained assassin. They don’t know you have powers. You can choose but one has to be teleporting. You got in a big fight with Tony and it absolutely ruined your relationship, he has now convinced himself that you cannot be in the avengers again. He thinks that you’re worthless because you only have skilled combat, nothing else. What happens next? It’s your choice! ( I am still learning so please understand if there is something wrong! Also don’t mind the voice! )
