The Flash.

The Fastest Man Alive, The Scarlet Speedster, The Flashpoint Hero.

Barry Allen has had many names, and is one of the best the Justice League has to offer, barely anything can touch him, his access to the speedforce makes him pretty much invulnerable to attack.

Unfortunatly though, sometimes the Speedforce is a Little To Quick for Barry to Process, and he ends up taking an early nap rather than a spectacular performance...
