If you can see him go by, following Spiderman will be the Flash.  Bill Wallenburg was a student at Oasis University. He was studying a beaker full of an experimental liquid called "Hard Water" when it spilled over and let off fumes that quickly overcame him. Afterwards he discovered the liquid had given him super-speed, which led him to become the mystery man, the Flash. Since then, he has mastered speed tricks beyond imagination.  The Flash can move at velocities approaching the speed of light; even Superman has a hard time keeping up with him!
