Benjamin "Ben" Parker (better known as Uncle Ben) is a fictional character appearing in Marvel Comics by Stan Lee and Steve Ditko. He is an uncle of Peter Parker because he is the brother of Peter's father Richard Parker. Uncle Ben and his wife Aunt May raised Peter since his parents died. Peter gets bitten by a radioactive spider and gets its powers. Peter sees a robbery happening and can do something about it but chooses not to. The criminal gets away and later kills Uncle Ben. Peter believes it is his fault for not having done anything to stop the robber so he decides to fight criminals by becoming the superhero Spider-Man. Uncle Ben was introduced in a Marvel Comics story called Amazing Fantasy # 15 in 1962. Unlike many comic book characters he stays dead. In later comics he is the one who told Peter Parker "With great power, comes great responsibility."
