How fast is Quicksilver?

When it comes to speed, few Marvel characters can compete against Quicksilver from the X-Men storyline. In both the comics and films, we’ve witnessed the character achieve extraordinary feats, where his abilities are on full display. Whether it’s the iconic slow-mo, time-freezing montage in X-Men: Days of Future Past or the alternate version of Quicksilver tearing through Ultron’s soldiers with sheer speed in Avengers: Age of Ultron.

Inside the Marvel films universe, there hasn’t been anyone yet who can compete with Quicksilver in terms of speed. So just how fast is he really?

How fast can Quicksilver run?

In X-Men: Apocalypse, Quicksilver achieves his most impressive live-action feat of speed in the film universe when rescuing students from the collapsing X-Men mansion, on multiple trips before its collapse. According to internet sleuths and amateur mathematicians, Quicksilver’s speed is around 2,050 miles-per-second, a number that is much faster than the speed of sound. That’s quite a bit shy of the speed of light, however, which clocks in at 186,000 miles-per-second.

While the Quicksilver from the Fox movies hits those impressive speeds, the Marvel Studios version of the character we see in Age of Ultron doesn’t seem as fast. The best evidence of this probably comes in his final scene in the movie, where he’s fast enough to save Hawkeye and an innocent child from a barrage of gunfire. Unfortunately, he doesn’t have enough speed to save himself as well.

How fast is Quicksilver in the comics?

The comic book version of Quicksilver takes the idea of speed to a whole new level, with the character having achieved some unbelievable feats during his run. The most impressive of these began when the character actually outran — wait for it — a radio frequency. That means that the character exceeded 500,000 miles per second…somehow breaking the speed of light.

Whether it’s a comic book or film featuring Quicksilver, other Marvel characters are going to have a difficult time keeping up with this speedster, to say the least.
