Peter Parker was raised by his Aunt May and Uncle Ben. His parents worked as scientists before they were killed. In the movies, Peter finds out what his father, Richard, was working on, just as he is bitten by a spider that gives him his superhero abilities. The more he finds on his father's work, the more he realizes the consequences if it is used by the wrong people. He initially becomes Spider-Man to hunt down the man who kills his uncle, but later uses it primarily to protect the people of New York City and prevent the wrong people from using his father's work.
