The Flash and Batman
Real Name: Barry Allen*
Occupation: unknown
Base of Operations: Central City
Voiced by: Charlie Schlatter
See Also: Flash (animated: JLU), Flash II: Barry Allen

The Flash is a super-speedster from Central City, and a member of the Justice League. He tends to be impulsive and speaks quickly. In addition to running fast, he can vibrate his molecules to phase himself and others harmlessly through matter. As a drawback, he also has a hyper-metabolism which requires him to eat massive amounts of food.

He first worked with Batman outside the League when the Mirror Master traveled to Gotham City with his henchwoman, Smoke. Duplicates—or rather mirror images—of the two heroes stole high-end optical components for him. When the Flash heard about the robberies, he sought out Batman and Robin. The trio teamed up to track down and defeat the villains. (“A Mirror Darkly,” 2007)
