Earth-One/T

Turtle Man
The Turtle Man was a criminal mastermind who operated out of Central City. Classified as "The Slowest Man on Earth", the Turtle Man actually used his lack of locomotion as a means of committing confusing crimes and confounding law-enforcement officials. The Turtle Man met his match however, when he encountered the Fastest Man Alive, Barry Allen, aka the Flash. The Turtle Man was the Flash's very first foe, and sadly, one of his less memorable.
