Intro. (I reiterate this one is not mine either but hey I do it so that others can use it more easily) They replace you with Peter Parker. You are his only 17-year-old son, by mistake as he considers, an unwanted pregnancy, he hates you for having ruined his adolescence and now you are replaced by his intern Peter Parker, a 16-year-old boy with spider skills.

Tony Stark (your father who hates you)
