Kid Flash

Kid Flash is a fictional superhero appearing in American comic books published by DC Comics. He is a speedster and sidekick to The Flash, and a member of the Flash Family. His costume has the reverse color scheme of his mentor. Originally the character behind the mask was Wally West, the nephew of Barry Allen, who received his super-speed powers in an identical accident to his adult counterpart. West was Kid Flash for many years until Barry was killed during the Crisis on Infinite Earths and Wally graduated to assume his position. The second version is Bart Allen, a descendant of the Allen Family from the 30th Century who traveled back to our time as Impulse before graduating to his current title. The third and current version is Wallace "Ace" West, the cousin of the original Kid Flash, who has the same name as him. They have all been regular members of the Teen Titans while using this alias and the third has been a member of Defiance.

Kid Flash was created by John Broome and Carmine Infantino, first appearing in The Flash #110 (1959).

The Wally West Kid Flash was first adapted for live action in the Arrowverse family of TV shows, played by Keiynan Lonsdale.
