Backstory: For many years Peter Maximoff was just a kleptomaniac until one day Charles and the X-Men came to him for his help to save the future of both humans and mutants. So he joined the X-Men and started saving the world from danger thanks to his incredible speed.

Background:

-Name: Peter Maximoff

-Age: 19

-Used to be a Kleptomaniac

-Magneto's son

-His actor was in WandaVision

-Everyone wants to know how fast he is

Powers:

-Superhuman Physique

-Limited Molecular Control: Quicksilver can vibrate his molecules to disrupt the intermolecular bonds around him, resulting in various effects, including phasing and molecular combustion. Quicksilver can finely control whether or not his speed will cause collateral damage, as he can run past a group of armed men and knock them over without harming Charles, Erik, or Logan. He also appears unconcerned about the effects of air resistance-caused high-speed friction, which should injure anyone he carries. During the extraction from the Pentagon, Erik only suffered minor dizziness after travelling with Peter in hyperspeed. This suggests that he can protect his "passengers" in some way

-Accelerated Momentum: Peter can see the world in a near-frozen state while he makes his move because of his rapid reaction and perception of the world. Due to the slowing down of his own time, gravity barely affects him, enabling him to run up walls. When it comes to kinetic energy and inertia, friction, and pressure, his speed is so high that they do not affect him. As a result, he has no sense of the mass or heft of anything as he travels at a hyper speed. Likewise, his visit to the mansion demonstrates that even an explosion appears almost frozen from his perspective

-Extreme Force Generation: Quicksilver's speed allows him to generate a lot of force, making the weight and hardness of other objects and people irrelevant. He also resists kinetic energy, inertia, friction, pressure, and vectors when moving at super-speed and sees the world in slow motion. A superfast cheek tap sent a grown man flying. Speedy removal of window curtains caused the windows and surrounding wall to explode. He could send Apocalypse flying by hitting him repeatedly at hyper-speed, mostly quicker than the villain could react

Equipment:

-Goggles

-Duct tape

-Sony Sports Walkmen

-Clip-on Headphones

Feats(Strength and Durability):

-Momentarily knock around Apocalypse

-Took out guys just by touching them

-Tanked water droplets while moving fast

-Flicked a piece of shrapnel

-Broke tiles on the wall just by running on it

Feats(Speed):

-Perceive a bee's wings, Storm's Lightning, bullets, Cyclops' optic blast, LCD devices turning off slower than him

-Got everyone out of the X-Mansion from an explosion

-Eat a biscuit and get a drink while a piece of bacon was falling

-Solved a rubiks cube while in Quicksilver time

-Ran from the X-Mansion to Egypt and back in a small amount of time

Stats(Strength and Durability):

-Tanking water droplets while running and flick a piece of metal

>According to Gubz, the force he withstand hits from water droplets, which means he tanked the force of multiple bullets. A bulletproof vest can withstand the force of 525000 PSI or 0.02 tons which is Small Building level in the kitchen scene in Days of Future past. In X-Men Apocalypse, Quicksilver was able to flick a piece of metal moving faster than a bullet, which is 9000x stronger than his durability feat in Days of Future Past, which is 180 tons of force(Multi-City Block Level)

>According to Gubz, Quicksilver's feet can produce 593000 tons of force or 654 Kilotons which is Large Town level

-Apocalypse scaling

>While moving fast he was able to briefly knock around Apocalypse who can take hits from Magneto after being upgraded to Horseman. And since Horsemen Magneto can destroy all of the man made structures in days which is Continent Level which is in the range of 760 Teraton to 4.435 Petatons and since Apocalypse is the one who gave the Four Horsemen their powers he should be more powerful than them around 4x stronger than them, that seems fair. That would make his maximum power around 18 Petatons which is Multi-Continent Level. I know that Quicksilver got his bones broken by Apocalypse like they were twigs but he would be able to perform the continent level feats when he's running

Final Verdict: Large Town Level to Continent Level with his speed

Stats(Speed):

Note: For every casual speed feat that Quicksilver does will be a 2x multiplier for his maximum speed

-List of things slower than Quicksilver

https://youtu.be/fmGBbtc1tgw

>Lightning = 62137.119 MPH or Mach 82 x 2 = 124274.238 MPH or Mach 163.3

>Bee's Wing Flap: 230 beats per second x 12 seconds / 2 = .00004529

>Bullet: 1800 MPH or Mach 2.4 x 2 = 3600 MPH or Mach 5

>LCD turning off: 20x the speed of light x 3 x 2 = 120x the speed of light

>Cyclops' Optic Blast: Lightspeed x 2 = 2x the speed of light

-Getting a picture in Egypt

>X-Mansion is in Westchester, New York and he ran to the Great Pyriamids of Giza  and back in 1 second. The distance between the places is 5,577 miles and doubling that will be 11154 Miles. So that means he's fast enough to run at speeds of 40,154,400 MPH or Mach 52751(Sub relativistic+) with the multiplier that would be 80308800 MPH or Mach 105501(Relativistic)

-Solving a rubies cube

>The World Record of solving a rubik's cube is 4 seconds and he did in 1 second

-X-Mansion explosion rescue

https://youtu.be/L5S5u60eeNg

>According to Gubz, Quicksilver fastest speed at the time was 38595840 m/s or 86336435.218 MPH or Mach 113420(Relativistic)

Final Verdict: 120x the speed of light in combat, running, and reaction speed

Weaknesses:

-Reckless

-Human weaknesses when not in Quicksilver time

-Likes to goof around when in Quicksilver time

-Even with his speed he can't do anything against stronger mutants like Magneto, Jean Grey, and Apocalypse
