  Spiderman was created in comics in 1962. It is a story about a shy and silent high school student, Peter Parker. After being bitten by a strange spider, Peter finds himself with super powers. With great power also comes great responsibility. Peter keeps fighting against evil men who want to harm people.
Spiderman is more like a friendly neighborhood student rather than a super hero. He experiences difficulties with friends and family.
In short, Spiderman remains everyman, “the super hero who could be you.” It is Spiderman’s simple humanity(人性) that helps him win millions of fans across the world.
