Bart Allen was the grandson of Barry Allen and his wife Iris. Bart suffered from accelerated aging and, as a result, was raised in a virtual reality machine until Iris took him back in time in order to get help from the then current Flash, Wally West. With Wally's help, Bart's aging slowed and he took the name Impulse. After his kneecap was shot while working with the Teen Titans, Bart changed both his attitude and his costume, taking the mantle of Kid Flash. During the events of Infinite Crisis, the Speed Force vanished, taking with it all the speedsters save Jay Garrick. Bart returned, four years older, and for a year claimed that he was depowered from the event. However, the Speed Force had not disappeared completely, and was absorbed into Bart's body, making it such that Bart contains all of the Speed Force. Bart's costume is Barry Allen's Flash suit. Bart Allen is the Flash who guests on the television series, Smallville in 2004, and again in 2007.
