"ZOOM The Reverse Flash Zoom is a villain from the 25th century who travels through time causing trouble for the Flash. He has a deep-seated hatred for all other speedsters and has made it his mission to destroy the Flash's legacy. Thanks to his time-traveling abilities, no one knows where Zoom will pop up next."

"The Reverse-Flash, the Scarlet Speedster's opposite in both costume (the yellows and reds are inverted) and morality, zoomed into the DC Universe in The Flash vol. 1 #139 (1963), written by John Broome and illustrated by Carmine Infantino. A resident of the twenty-fifth century, demented genius Eobard Thawne (aka Professor Zoom) is fixated upon the twentieth-century Flash (secretly police scientist Barry Allen). Discovering one of the hero's original uniforms in a time capsule, Zoom scientifically boosts its original wearer's residual super-speed energies (defined in later texts as the 'Speed Force') and infuses the suit, which he dyes, with the ability to enable him to run at superhuman velocities. Becoming the Fastest Man Alive of the future, he zips through a crime wave until the Flash, on a time-traveling mission in Zoom's era, trips him up."

"Whether he's called the Reverse-Flash or Professor Zoom, Eobard Thawne is a light-speed killer unhindered by the laws of space and time.
"John Broome and Carmine Infantino unveiled the character in The Flash #139 (September 1963). A resident of the 25th century, Eobard Thawne traveled into the past to meet The Flash and to meddle in the life of his alter ego, police scientist Barry Allen. Though he possessed the same abilities as his target -- able to run faster than thought and phase through solids by vibrating is body's molecules -- Thawne's color-swapped costume marked him as a true 'Reverse-Flash.'"

"The colors of Zoom's costume are the exact opposite of the colors on the Flash's costume."
