Wally West
The Flash in the "Justice League" animated series is voiced by Michael Rosenbaum (Lex Luthor on the television series "Smallville"). This Flash is eventually identified as Wally West; however, he is an amalgamation of Barry Allen and Wally West (in "Justice League Unlimited", Wally is a forensic scientist, which was Barry's profession. Wally in the comics is an auto mechanic).
