5. He's Faster Than Superman
Despite the fact that Barry Allen is named The Fastest Man Alive, comic book fans have spent years bickering over who's faster; The Flash or Superman. DC Comics ignited the debate over a number of years by setting up races for the two heroes only for them to be called off at the last minute because a super villain attacked or something similar. However, the question was answered once and for all when Barry completely and easily managed to outpace the Man of Steel. The Speed Force just gives The Flash a clear advantage, and while Supes can nearly keep up with his Justice League ally, he definitely can't beat him.
