As the current
In the comics, Superman flies and surpasses the speed of light and eventually even reaches the "limits of existence." However, since flight isn't something to be considered, it's most important to note he rivals Flash's speed.
In a competition of speed between the Blue Blur and the Scarlet Speedster, it will take more than math and science to really comprehend their overall speed. However, taking all things we know into account, Flash would win a typical race against Sonic the Hedgehog and come out as the faster of the two.
While Quicksilver is definitely one of the fastest speedsters in the Marvel universe, fans have already seen how his speed stacks up to The Flash.
Technically, it would be the Flash. As I mentioned in my last post working out how fast Barry has run, he can run up to 99.99999999999999982775% the speed of light, 670,616,629 mph or 482,469,193 km/h or Mach 874,030.
Wally West is the Fastest Flash and is arguably the fastest being that has ever existed, as said by Max Mercury—and it has been remarked that Wally and Barry are the only two speedsters that were fast enough to even outrun death itself.
Like other speedsters, Godspeed can run up to 10 times the speed of light by entering the Speed Force.
In a direct physical speed matchup, The Flash will definitely trounce Thor.
Flash by a long shot. Flash can run fast enough to run on water, dodge bullets, and pass through objects. Thor usually doesn't run in battle. He flies with the help of his hammer.
By being able to travel in a dimension where time has been eliminated, Dragon Ball's Goku proves that he is technically faster than even the Flash.
@IGN The Flash can travel faster than the speed of light. Sonic is just a slow poke.
As the current Flash in DC Comics, Wally West is one of the fastest men alive, easily able to outpace people like Superman and manage to keep up with people like Barry Allen, but a long time ago Wally admitted that the Reverse Flash is much faster than him.
Storm & the Brotherhood of Mutants #1 re-introduces the young mutant Loolo, first seen in X-Men Red #6, as the incredibly fast hero called Quick.
While Quicksilver is often thought of as the fastest of the Avengers, one hero fans know from the movies can actually outrace him when they need to. Many heroes possess enhanced speed, but Pietro Maximoff is generally considered Earth's fastest man (at least in Marvel Continuity).
Quicksilver is, quite literally, unbelievably fast. Others around him assume he's doing nothing even when he suggests slowing down camera footage, so they can see what he's been doing. It provides some fantastic humor to an incredibly serious superhero story.
Hurting the Hulk would be hard for the Flash, especially since every missed attack would make the Hulk angrier. However, the Flash can always deploy the infinite mass punch, his most devastating attack. It would be a last resort but it would give the Flash the win.
The Flash would absolutely destroy Iron Man in a fight, and like Machinehead, the Flash would do so in the funniest way.
While it is fairly obvious that the Flash could run circles around Thanos under normal circumstances as his powers make him virtually untouchable, there wouldn't be much the Scarlet Speedster could do if he was around for Thanos' Infinity Snap as there is no way to outrun the god-like power of cosmic chance.
The lone Godspeed proclaimed their defeat due to Impulse's recklessness, before attacking the Flash. But the Flash was able to phase through his attack and the Godspeed, defeating them.
Technically, Spidey tends to have a longer window of time to react than the Flash, so his ability could be seen as more useful. Of course, Spider-Man isn't nearly as fast as the Flash, so handing him an extra second or two doesn't give him any distinct advantages over the speedster.
2) Saitama (One-Punch Man)
Saitama will always be faster than The Flash, since his core characterization is as a fourth-wall-breaking, supreme-reigning anime hero. There's little the DC Universe's speedster can do to overcome this obstacle.
Superhuman Speed: The Black Flash can move at vast superhuman speeds, easily keeping up with Barry Allen, and surpassing the speed of light.
He is stated to be capable of exceeding light-speed (299,792,458 m/s), which could explain why he can go through the breaches between Earth-2 and Earth-1, and can move at speeds of Mach6-8, easily outmatching Barry's speed in their first fight.
Godspeed is the sixth villainous speedster to appear in the show. The first being Eobard Thawne, the second being Zoom, the third being Trajectory, the fourth being The Rival, and the fifth being Savitar. Additionally, he is the fourth one to be a main villain.
