Wally West got his powers at the young age of ten when he visited his uncle's laboratory (Uncle Barry Allen who was already Flash). He got some chemicals on him and gained the power of super-speed. Since he was so young he became "Kid Flash". Later on he would take over the role of his uncle as Flash. He is somehow the Flash from the Modern Age. He made his first appearance as the Kid Flash in the "Flash#110" in 1959 and he was created by John Broome and Carmine Infantino.
