What is Wallcrawling?
Wallcrawling is the ability to stick to and crawl on walls. Spider-Man would be the one to make wallcrawling famous. The comic version could enhance inter-atomic forces in his body, but the film version used tiny hairs all over his body to stick to walls. Beast also has a limited form of wallcrawling, though instead of using tiny hairs, he uses his natural claws to penetrate walls. Other wallcrawlers include the Spider-Woman family, Spider-Girl, the Lizard, and Nightcrawler.
