Wally West Aka Kid Flash is the kid of Impulse
Shortly after meeting Flash's friend Elongated Man, Kid Flash received his own unique costume. The Flash, who had been toying with a new design for Wally, was inspecting an alien mind over-matter machine when, in a burst of light, the new costume sprang from his mind and onto the body of his protégé. Since the new outfit exposed Wally's bright red hair, Flash provided his costume-storage ring with a special instant-dye spray with which he could easily change his hair color, as Wally, to brown.
