Kid Flash is a character who appears in LEGO Batman 3: Beyond Gotham.
Wally West is a fanboy of The Flash. Unbeknownst to him, his Aunt Iris's boyfriend, Barry Allen, is the scarlet speedster and able to arrange for Wally to meet his hero. The Flash replicates the chemical setup which gave him powers when a lightning bolt crashes and douses Wally with them, giving him the same powers as The Flash. Wally joins Barry as his sidekick, Kid Flash.
Kid Flash is a founding member of the Teen Titans, joining Robin, Wonder Girl, and Aqualad. Wally is later manipulated by Raven into joining the refounded Titans, but leaves the team after they are betrayed by Terra, intending to retire. However, a short time later, Wally's now-uncle Barry dies while defending the universe from the Anti-Monitor. In memory of Barry, Wally becomes The Flash while Barry's time-displaced grandson Bart becomes Kid Flash (after originally being called Impulse). As The Flash, Wally is a member of both a reunited Titans and a mainstay on the Justice League until Barry returns from the dead and they share the mantle.
