Who hasn't pretending to be the fastest man on Earth before? The Flash is a superhero in the DC universe that lives alongside Superman, Batman, Wonder Woman, and the rest of the Justice League. The Flash mantle has been worn by several people including Barry Allen, Wally West, and Jay Garrick. No matter which one you like more, you are always a part of the Flash family.
Tap into the speed force like the scarlet speedster and run laps around everyone at the gym. Wally West is not only so fast he can go back in time, but Wally has also won a race across the universe against a teleportation device.
For those times when you are hoping to not be seen at the gym. Suit up in stealth mode as the Flash for your next supervillain, the weight rack!
Be in the mode with a work out shirt designed like the Kid Flash's costume. Wally West (and then Bart Allen) was a pivotal part of Young Justice in the same way the Flash is an original member of the Justice League.
Be the rival to greatest nemesis as the Reverse Flash. Eobard Thawne is from the distant future but came back to destroy the life of Wally West. While it doesn't always work, he made a last impression by going back in time and framing his father for the death of his mother.
Filling the role as the embodiment of Death for speedsters, the Black Flash will eventually get all speedsters.
