"The Fastest Man Alive" is a moniker that every fan of The Flash should be familiar with by now. Barry Allen is the most well known Flash today thanks to CW's The Flash tv series, but he's far from the only speedster in the history of DC Comics. These speedsters almost all share a common connection to the Speed Force, a power so strong and ill-defined that even writer and Flash aficionado Geoff Johns had to call it "Basically Magic."

The Speed Force a cosmic realm of kinetic energy that acts as both a power source for various heroes and villains and a get out of jail free card for writers that lets the Flash do almost everything from time travel to creating matter to even flying through the air. One of the most consistent (and surprisingly useful) powers granted by the Speed Force is how it affects the user's brain power. Every version of the Flash is able to not only move fast but the process and retain information at superhuman rates.

This is more practical than it sounds-like an incident in The Flash #2 where Barry Allen managed to become a master architect and repaired a burned down apartment building all in the span of a few seconds.

But even that's not the most impressive feat of the Flash's super-powered brain. In The Flash #19, Barry Allen proves that he can think faster than the best computers in the world, even one build by his fellow superheroes. During the comic Barry travels to the Justice League Watchtower to do research on why his Speed Force powers haven't been working properly. While there he calls the League computer "a little slow"-despite fellow leaguer Cyborg's claim that the computer can run over 100 trillion calculations per second! This would mean that Barry's brain is able to work faster than the most advanced computer ever built and that he could potentially be one of the smartest comic book characters of all time if he ever chooses to dabble in super science in the future.

The most consistent thing about the power and limitations of the Speed Force in comics is its inconsistency. At its peak it allows speedsters to outrace primordial concepts like time and death, but having a superhero who can do literally anything doesn't make for good drama. Because of this, the Flash only ever gets to move that fast when there's a crisis level event on the horizon. Regardless, The Flash proves just how deceptively useful a simple powerset like super speed can actually be, and his ability to not just move fast but solve problems at lightning speed has made him one of DC's most powerful heroes of all time.
