- Wade Williams is a senior high school student at Pointview High. During a high school baseball practice Wade got bit by a spider while on the pitchers mound. There was something about the bite that was more than just painful.
- The next day at school, Wade witnessed a student panicking because he was stuck on the top of the entrance to the school after climbing up there to retrieve a thrown football. Wade felt his hands and feet tingling and he had an urge to climb up the building to save him.
- That night, Wade realized that his spider bite gave him a superpower to climb walls and the desire to save people. He put together a costume that would identify him as Webb-Man.
- Webb-Man is able to climb walls using microscopic hair like barbed fibers that project from his hands and feet. These fibers come out when he gets a spidy sense that there is someone in need.These microscopic projections use Van Der Waals forces to climb on walls. The electrons in the fibers are constantly zipping around, sometimes the molecules electrons on the fibers are all grouped to one side of the atom which gives that side a slight negative charge and the opposite side a slight positive charge. If the side of the fiber closer to the wall is, just for a moment, slightly negatively charged, then it will induce a slight positive charge in the wall. By repelling those electrons in the wall closest to the surface, exposing the positively charged ions, and an attractive force between the fiber and the wall will result in being able to stick to walls and climb walls.
- While climbing the wall, Webb-Man has to overcome the force of gravity acting on his body by producing a force of 559 Newtons. To be able to produce this force of 559 Newtons Webb-Man will have to create 2.5x10^-3 coulombs of charge at a distance of 0.001 meters. This means that to be able to climb Webb-Man will need 6.2x10^-8 coulombs in each appendage to be able to climb walls.
- As Webb-Man was testing out his wall sticking power in his room he realized there was a projection protruding from his right ventral wrist area. He pressed on the projection and with great force a spider web shot out across the room and onto the closet door. He tested the strength of the webbing by opening and closing the door. The webbing was strong and Webb-Man realized this would be an important part of his superpower.
