Spider-Man (Peter Benjamin Parker) is a fictional superhero in the Marvel Comics universes. A bite from an irradiated spider causes a variety of changes in Peter Parker's body, giving him superpowers. In the original Lee-Ditko stories, Spider-Man has the ability to cling to walls, superhuman strength, a sixth sense ("spider-sense") that alerts him to danger, perfect balance and equilibrium, as well as superhuman speed and agility. In story-lines published in 2005 and 2006 (such as The Other), he develops additional spider-like abilities including biological web-shooters, toxic stingers that extend from his forearms, the ability to stick individuals to his back, better control over Spider-sense for detection, and night vision. Spider-Man's strength and speed have also increased beyond his original limits.
