1 Barry Allen (Earth-Prime) Barry Allen is known as the Fastest Man Alive, and that isn't just a cute nickname. Eobard Thawne said that the speed of Barry is potentially unlimited. He reached Mach 13.2 from tachyons and continued to increase his speed to even faster levels since that time.
Barry Allen This gave him abilities like superhuman speed, senses and reflexes, but most importantly, it established his connection with the speedforce. The fastest that Barry Allen has gone is the speed of light in a vacuum, which is 3*108 meters/sec.
This super-speed is derived from his mainline-connection to the Speed Force: a vaguely-defined extra-dimensional and infinite energy source from which most speedster heroes gain their powers. Wally is widely considered to be the Fastest Flash, and is significantly faster than Barry Allen.
