Bart, the child from the future known as the hero '''Impulse'''. After [[Max Mercury]] disappeared in the timestream, Bart took up residence in [[Keystone City]] with [[Jay Garrick]], the original Flash, and Jay's wife Joan.

When a mysterious android from the future known as [[Brainiac 8|Indigo]] attacked the Titans and Young Justice, it resulted in the apparent deaths of [[Donna Troy]] and [[Lilith Clay|Omen]]. At Donna's funeral, [[Dick Grayson|Nightwing]] disbanded the Titans. The members of Young Justice, especially [[Cassie Sandsmark|Wonder Girl]], felt responsible for the tragic deaths.<ref>''Titans/Young Justice: Graduation Day'' #1-3 (2003)</ref> This led Wonder Girl, Robin, Impulse and Superboy to form a new group of Teen Titans under the guidance of the more experienced [[Cyborg (DC Comics)|Cyborg]], [[Starfire (Teen Titans)|Starfire]], and [[Beast Boy]].<ref>''Teen Titans'' (vol. 3) #1 (July 2003)</ref> Despite Wally West's misgivings, Bart accepted an invitation to join the new Teen Titans.<ref>''Teen Titans'' (vol. 3) #6 (December 2003)</ref>

Bart was later injured when [[Deathstroke]] put a shotgun to his leg. Thankfully, his accelerated healing enabled a handful of surgeons to replace his kneecap with an artificial one, and Bart was back on his feet in a matter of hours, but the effects of this encounter were much more than physical. Feeling unsure and tired of being underestimated, Bart went to the local public library and read every single book in the building. He retained that knowledge and balanced it with lack of experience. With a renewed sense of confidence, Bart left his impulsive rep behind and returned to the team as Kid Flash.<ref>''Teen Titans'' (vol. 3) #4 (October 2003)</ref>

When [[Superboy-Prime]] ran amok during ''[[Infinite Crisis]]'', Kid Flash and the super-speedsters raced to stop his rampage. While running to subdue the deranged Teen of Steel, Wally West disappeared in a burst of lightning (later to return). Meanwhile, the speedsters' combined might defeated Superboy-Prime, but severed their connection to the Speed Force in the process. Bart returned to warn the heroes of Superboy-Prime's escape. But while mere moments had passed in the present, Bart returned from his time-bending journey four years older. Bart handed his grandfather's costume to Jay Garrick, claiming he used up all his speed powers during the final battle.<ref>''Infinite Crisis'' #7 (May 2006)</ref>

Bart still had his powers, but faced with the guilt over Superboy-Prime's escape, he initially decided to retire his costume. He took a job as a factory worker in Keystone City, but soon realized he must use his abilities to protect innocents. Although Bart found new challenges in harnessing the speed force, he accepted his destiny as the latest Flash in the Allen family tradition. In his efforts to tame the speed force inside him, Bart turned to S.T.A.R. Labs intern, Valerie Perez, and their relationship quickly blossomed into a full-blown romance.<ref>''The Flash: The Fastest Man Alive'' #1 (June 2006)</ref>

Once accepting the mantle of the Flash, Bart moved to [[Los Angeles, California]] and enrolled in the Police Academy. Robin asked him to join the Titans but Bart declined, saying he'd rather work towards membership in the [[Justice League|Justice League of America]]. Shortly after resuming the mantle, Iris Allen warned Bart that if he fought the newly formed league of Rogues, he would not survive. [[Inertia (DC Comics)|Inertia]], in a plan to steal the speed force energy for himself, manipulated the [[Rogues (comics)|Rogues]] into battle with Bart. As a depowered Bart fought valiantly against the combined might of the Rogues, he saw the spectre of the [[Black Flash]], and died as Iris Allen and Valerie Perez were left to mourn him.<ref>''The Flash: The Fastest Man Alive'' #13 (July 2007)</ref>

Later on New Earth, during the ''[[Final Crisis]]'' storyline, [[Superman]] was called to the thirty-first century to assist the [[Legion of Super-Heroes]] in fending off Superboy-Prime, who was thrown to the future in the aftermath of the destruction of Earth-51 and the ''[[Sinestro Corps War]]''. Prime, raging about his minor place in history as a Superman rival, released the [[Legion of Super-Villains]] from the prison planet Takron-Galtos and waged war on Earth and the Legion. In response to this, Brainiac 5 summoned the Legions of Three Worlds (alternate earths) to combat Prime's forces. Revealing that the Legion had captured "living lightning" in the Legion's last trip to present Earth in ''[[The Lightning Saga]]'', Brainiac 5 had Legionnaire [[XS (character)|XS]] run on the cosmic treadmill while the three [[Lightning Lad]]s activated the "lightning rod" to release the living lightning. Although he tried to stop them, Superboy-Prime was unable to stop the lightning from being unleashed. A fully formed alive-and-well Bart Allen, in his Kid Flash uniform, appeared before him.<ref>''[[Final Crisis: Legion of Three Worlds]]'' #3 (February 2009)</ref>

When the New 52 universe began, the Kid Flash working with the Titans was known as Bart Allen. He ended up with a different backstory, and eventually was written out of the storyline. He was later replaced as Kid Flash by Wally's cousin, Wallace West.
