Amazing Fantasy 15 Issue 1 is the debut of Spiderman. In the previously named issue we read about a teenager called Peter Parker, whom is something of a scientist in the making. With the nickname of a bookworm. In the space of a day, Peter Parkers life changes dramatically, after having being bit by a radioactive Spider. Which ultimately gives him his super spider powers. At the beginning, Spiderman uses his new abilities to try and make a living on Television. But when his Uncle Ben was murdered by a man whom Spiderman could have stopped from robbing a building a day before, he devoted his life to helping people. Realising that with Great Power Comes Great Responsibility. Spiderman was born.
