the present where The Flash, Wally West, tricked Bart into a race around the world. By forcing Bart into an extreme burst of speed, Wally managed to shock his hyper metabolism back to normal. Because he had spent the majority of his childhood in a simulated world, Bart had no concept of danger and was prone to leaping before he looked. The youth proved to be more trouble than Wally could handle, and he was palmed off onto retired superhero speedster Max Mercury, who moved Bart to Manchester, Alabama.

While recovering, Bart read every single book in the San Francisco Public Library and reinvented himself as the new Kid Flash. Once healed, the artificial knee did not affect his ability to run at speeds approaching that of light, but reminding him that he needs to think first rather than to act impulsively. When Robin reminded him that by becoming Kid Flash, he would
