Blink and you might miss him flying by. The Boys Young Justice Kid Flash Costume is of Young Justice's fifteen-year-old speedster. The Kid Flash is the sidekick of the classic DC Universe hero, the Flash. While he doesn't have all of the elder speedster's ability, he's got more style and (dare I say) flash as is demonstrably clear on the show and in this costume.
The Boys Young Justice Kid Flash Costume comes with a Kid Flash mask, a jumpsuit, and gloves. No word on whether it allows you to move at nearly the speed of light or not. We'll get back to you on that one.
