Game Description
“After an electrical accident at his lab, scientist Barry Allen was left with the ability to move, think and react at super speeds. A member of the Justice League, The Flash uses his super speed to fight crime.”
Powers and Abilities
Barry Allen is capable of running faster than the speed of light creating vortexes charged with electricity and, at times during the Silver Age, described as faster than the speed of thought. In Flash #150, "straining every muscle," he ran at ten times the speed of light. However, when he pushed himself further (during the Crisis on Infinite Earths) he appeared to waste away as he was converted into pure energy, traveled back in time, and was revealed in Secret Origins Annual #2 to be the very bolt of lightning that gave him his powers.
Barry Allen possesses abilities that Jay Garrick has not always been able to duplicate, most notably the ability to "vibrate" in such a way as to pass through solid matter. Allen has regularly engaged in time travel using the Cosmic Treadmill device (he no longer needs this to conduct this feat), and is able to "vibrate" between dimensions. Barry is unique among Flashes and most characters in the DC Universe in that he has complete control over every molecule in his body. He has recently been revealed to not only be connected to the Speed Force, but is the very source of it, generating it with every step he takes. As such, he presumably has some of the Speed Force-related abilities other speedsters have demonstrated (such as lending and stealing speed), though he has yet to demonstrate such abilities. This alone is enough to make him one of the most powerful beings on Earth, and perhaps in existence. He is also immune to telepathic attacks and control, as he can shift his thoughts at a speed faster than normal thought.
It was initially believed that Barry Allen was unable to alter the timeline, due to that power being tied to the Reverse-Speedforce held by Professor Zoom. It has since been revealed that Barry Allen does possess that power but, due to him researching only the most utilitarian effects of the Speed Force, he never mastered it. Still, as showcased in Flashpoint, Barry Allen lacks the subtlety and knowledge of time-travel mechanics needed to enact specific changes. This was shown during his first attempt at using the aforementioned power, to turn his own timeline into a dystopia instead of simply reverting a small change enacted by Zoom.
