Wally West
Most of the elements in the television show were taken directly from the main story line in the first Wally West Flash comic books: The S.T.A.R. Labs researcher Tina McGee, she and her husband's research into speed, her husband's allegedly fatal accident with their speed research, the Flash's ravenous appetite, heat problems (which were mitigated by the TV show's Flash suit), and speed limit on the order of the speed of sound were all elements from the main Wally West comic book storyline.
