Fox' Quicksilver vs MCU Makkari

[Twickster]

He's faster than she is by a fair margin. In that scene, everything is in such slow time that a sci-fi powerplant explosion capable of destroying a gigantic mansion nearly instantly is almost not moving, and the people are absolute statues. He's wandering around casually, then will grab someone and take them 500m away, then run back, all in a fraction of a second in that crazy ass slow time.

For the sake of argument, let's say that the explosion wave is expanding at 500m/s, which is a lot, but it's not at all ridiculous given the nature of the source and the effect it has (totally annihilating the gigantic mansion and destroying everything for a decent radius around the mansion as well). Quicksilver grabs people, runs them 500m away through corridors and everything else, and makes it all the way back in the time that fragments of the explosion move less than a half-meter. He does this casually, never really looking like he's straining. So, he's covering 1000m or so in at most 1/1000th of a second.

He's therefore moving at least 1,000,000 meters per second just on those back and forth trips. And he does this all while screwing around. Extrapolating further, he searches every inch (it shows him looking in cabinets and closets and stuff) of the massive mansion (the complex has to be a, I dunno, 50 thousand square meters - given accomodations, classroms, labs, training stuff above and underground, etc.) when he's clearly never been there before. He makes, I dunno, 40 or 50 back and forth 1km runs with people, saves all of the others with throws into drapes or lakes, all in substantially less than a second. That alone puts him comfortably above Makkari. It's a silly feat, but it's absolutely consistent with the guy' presentation, and it's not like he's ever not been fast enough.

But wait! There's more! This explosion is an energy blast, and releases a significant amount of heat. Heat propagates as infrared primarily, and, hang on, how fast does that go again? Because at the beginning of the rescue, he runs into the mansion, searches enough to find the center of the blast, and is standing there, screwing around, moving pieces of it away (which are stuck in place relative to him, again, still just playing here) all while those terrible energies are there, moving at the speed of light, and he doesn't so much as singe a hair. The only way that happens is if he's a very high fraction of lightspeed.

He's fast enough that she won't see him coming, and won't be capable of doing anything to reduce the edge his speed gives him against her.

That's my take, anyway.

So, I still don't see an exact claim from you on Quicksilver's speed (i.e. how much, exactly, do you think his speed is, in numbers terms?).

Because from the very comprehensive calculations in this video (which, among others, includes the detonation velocity/speed of the expanding explosion, the size of the building the X-Mansion is based on (which, as it is shot in a real castle, is completely knowable); the exact number of times he is shown onscreen going in-and-out of the mansion (counted, 26 times); the distance he deposits the people from inside to outside, doubled the distance of travel to get back in again (200 meters in and out), etc.) his speed is in the range of mach 3,500.

If you recall, a simple back of the envelope calculation of Makarri's speed feat is mach 5,000.

Yeah, no. On this physics does not operate the way you think it does, because of the insulative properties of an atmosphere. Heat does not radiate outwards from an explosion at the speed of light, as you seem to think. Not that the heat would be the major danger involved in such an explosion anyway instead of the actual explosive force of the explosion (which the video also mentions, average detonation velocity of substances is 23,000 ft/s). In short, avoiding that explosion takes nowhere near the speed of light.
