Did Marvel create the fastest being in the entire universe as Quicksilver, or was it DC with the Flash that forever changed the definition of fast?
Marvel and DC are two different worlds which means that if you dragged the Flash to Marvel, his powers would not work and vice versa. But since it is a comparison, we will let that part slide for argument’s sake.
So let us dive right into the ultimate speedster battle – Quicksilver VS the Flash.
The fastest of the two is the Flash!
It has been proven from time to time that the Flash is the fastest man alive. He is much faster than Superman, and also he can travel faster than instantaneous transmission.
Going into the technical terms, Quicksilver can move at a maximum speed of Mach 640. The Flash moves at a speed of 23,759,449,000,000,000,000,000,000,000,000,000,000,000,000 times the speed of light (23 tredecillion times the speed of light)!
Flash is the epitome of speed, just as Superman is the epitome of strength. Flash can run in the air. He uses the water particles in the air to excel himself into the air. Flash can also see the speed of light. In a comic issue, the Flash saved the entire city from an explosion, by moving them to a safe hilltop. He traveled at a speed of 13 trillion times the speed of light. He can see stuff in an attosecond (an attosecond is 1,000,000,000,000,000,000th of a second or a quintillionth of a second). It means that he can see a lightning bolt as if it was not moving.
On the other hand, Quicksilver is also pretty fast. He could first run a little bit faster than the speed of sound(4-5 times the speed of sound), but ever since he was exposed to Isotope E, he could run at SuperSonic Speeds – 10 times the speed of sound. Quicksilver can break the time barrier. In an Avengers comic, he traveled 12 days into the future to see what happens in an upcoming battle. Quicksilver can see things at the speed of sound, which means that he can see stuff in a millisecond (a millisecond is the 10th of a second). It is nothing compared to an attosecond.
In X-men: Days of Future Past, when Quicksilver was running the bullet from the gun, it was moving pretty slow. In the new Flash series, Barry was in the car with Joe West, and a lightning bolt went through the car, but before it could hit the bottom of the car, Barry saw it and got Joe out of there with no sweat.
The lightning was 132 times faster than the bullet considering that lightning travels at 224,000 mph while a bullet at 1,700 mph. It directly means that the Flash was moving about 132 times faster than Quicksilver.
One of Flash’s most impressive stunts involved his race against the Black Flash, an embodiment of death. During their race, the Flash (Wally West) ran so fast that he jumped forward in time by millions of years until nothing existed, resulting in death no longer being a concept. As a result, the Black Flash was no more. The Flash outran the concept of death. To top it all, it was nothing more than a casual jog in the list of feats of the Flash.
In the comic The Human Race, a group of cosmic gamblers who existed at the edge of the universe traveled around the cosmos and made bets with each other for fun, as they were so powerful, this was their only form of entertainment. They picked speedsters throughout the cosmos and made them race against each other in their bets. The speedster who lost got his home planet destroyed.
In one such bet, Earth gets the attention of these cosmic gamblers. Wally West, the fastest man on the planet, became the representative of Earth.
During the race with a fellow speedster in the bet, Wally, realizing that the cosmic gamblers will never refuse a friendly bet, makes a bet with the cosmic gamblers that he will reach Earth first even though the cosmic gamblers can teleport to any location in the cosmos instantly. It appears to be a ridiculous gambit, and the cosmic gamblers agree.
Before the race begins, Wally tells everyone on Earth to run. Tapping all the kinetic energy generated by the people of Earth, the kinetic energy from his fellow speedster with whom he was earlier competing, and tapping deeper into the Speed Force than ever before. When the signal is given, he moves in a time interval so infinitesimally small that it cannot be measured, and within that time, he reached Earth even before the gamblers could teleport.
Calculating the distance between the Gamblers’ ship and Earth, and the time taken to travel, he moved at what people call the trans-time velocity, a velocity so large that it is unfathomable. He wins the bet, saves Earth, and his adventures continue.
Although the Flash is super fast, the Quicksilver is not to be underestimated. In the Marvel Cinematic Universe, unfortunately, no concrete information regarding Quicksilver’s maximum speed has been made public as of yet. During the movie, we see Quicksilver outrunning Mjolnir and arrows, as well as altering the trajectory of an arrow in mid-flight. It is not necessarily indicative of the limits of his abilities. Even the junior novelization only describes his speed as “faster than a bullet train” and “faster than a jet”.
As per the comics, following the loss of his mutant nature, Quicksilver exposed himself to the Terrigen Mists, resulting in him now possessing the power to vibrate his atoms so quickly he travels forward in time. The molecular speed that he generates displaces him out of the mainstream time and space so that he can propel himself into the future. He can leap from thirty seconds to up to twelve days, and remain for several minutes to several hours before being recalled to his present time. As he returns from his trip, he returns the exact moment he left to appear that he has been gone for half a nano-second. He can bring inorganic objects from the future back to his correct time, although it has not yet been shown what would happen if he attempted to bring organic objects with him.
In terms of pure speed, in their respective universes, the Flash is way faster, by far, than Quicksilver. But when Marvel and DC have had crossovers between Universes, Quicksilver’s powers remained constant due to his mutant origins (his body is organically adapted for the use of superhuman speed). Whereas the Flash’s speed is an aspect of an external power that he may not have access to in the Marvel Universe.
Since crossover events are exceedingly rare, it is safe to assume that the Flash is consistently faster than Quicksilver.
