For most of our fastest things, we can confidently point to recorded times, broken records or even extraordinarily educated guesses. But in the case of the fastest superhero, we're left to throw the debate to the passionately opinionated masses. And the answer is tricky.
If you're like me -- not so much a fluent comic obsessive, but conversational in the difference between Marvel and DC -- you might assume that The Flash is the obvious winner. He's able to run at almost light speed, and some iterations say he can run at light speed or faster. Besides running, he can do pretty much everything else at hyperspeed, too [source: DC Comics]. The guy is known as the fastest man in the universe. Easy choice.
But don't forget about Silver Surfer, a character who is so fast that he travels through hyperspace and exceeds light speed [source: Marvel]. Look on any conversation thread debating the relative speed of comic book characters, and you'll find the Silver Surfer has staunch defenders. Even if The Flash were to keep up with Silver Surfer, they point out, he doesn't have the stamina to keep up forever.
