Quicksilver's speed, while on the lower end of Marvel's speedsters, has allowed him to take down Magneto several times. The times Quicksilver beat Magneto were highly dependent on Magneto not expecting Quicksilver's attacks.
Wolverine has tried to kill or otherwise attack Magneto many times in X-Men canon, sometimes in the comics and other times in the movies/cartoons, and every time ends the same: Magneto easily defeats him.
Wally West is the Speed Force's undisputed king. Having once been trapped in the Speed Force, Wally has built an almost spiritual connection to it. He can travel at speeds far superior to his predecessors, all of which could already beat Quicksilver.
Powers. Quicksilver is an Alpha mutant, allowing him to move at lightning speed. He had super-fast reflexes and his brain actually processed information much faster than most computers.
Superhuman Strength: Quicksilver is able to use his speed to increase his strength in such a way that his blows have incredible power, to the point that he was even able to gain the upper hand on and beat up Apocalypse easily and could knock full grown men out with a simple tap from his finger.
Quicksilver is simply put, much too fast for Hulk. Hulk relies on his brute strength and hand-to-hand combat abilities to face enemies who are some of the strongest in the Universe. However, when facing a foe this fast, the Hulk may have a hard time landing any clean shots on him.
With enough training, Quicksilver would have been more than capable of defeating Thanos when he finally arrived in Infinity War. Unfortunately for the Avengers, Quicksilver heroically sacrificed his life in order to save Hawkeye and a civilian boy during the Battle of Sokovia.
Believing Magneto to be responsible, they attacked him and his family in Genosha. There, Layla Miller restored his memory as well, and the heroes realized that Quicksilver had been the one to manipulate Wanda into warping reality. Angry over what his son had done in his name, Magneto lashed out and killed Pietro.
WHO IS QUICKSILVER? Born to a Serbian-Transian couple, Django and Marya Maximoff, Pietro and his twin sister, Wanda, were born with innate special powers. While Pietro had phenomenal speed, Wanda possessed hex abilities.
The Flash is faster - and it ain't even close. Quicksilver's top speed is Mach 10 - a little slower than 8000 miles per hour. This makes him one of the fastest beings in the Marvel universe, with only the likes of Marvel's heaviest hitters (Sentry, Blue Marvel, etc.)
The fastest Quicksilver or speed we know, so far, is the Ultimate Universe Quicksilver who could go at speeds Mach 20, which is good but only a little bit higher than Earth-616 Quicksilver who could move at speeds of Mach 10.
A-Train's highest clocked speed in the show was 371 m/s and in the comics could even reach mach 3 speeds. Quicksilver on the other hand has ran as fast as light. About Mach 873226. Over 290 thousand times faster than A-Train's fastest recorded speed in the comics.
Quicksilver's speed, while on the lower end of Marvel's speedsters, has allowed him to take down Magneto several times. The times Quicksilver beat Magneto were highly dependent on Magneto not expecting Quicksilver's attacks.
Matthew Waterson noted to Phase Zero that Thanos' Infinity Gauntlet is metal, suggesting that Magneto could have easily stripped Thanos of his most powerful weapons, rendering him all but powerless, and making him easier to take down.
Charismatic and powerful, Magneto has been known to defeat many enemies including Sentinels and Wolverine. In a battle against Superman, his powers would not help him. Although he would put up a good fight, the Man of Steel is anything but magnetic.
The battle comes to a definitive end with the Master of Magnetism officially beaten by Iron Man, left conscious and floating in space, trying to advise the Avenger on his next move. The winner between Iron Man and Magneto is undisputable.
Both Alpha and Omega Level of Quicksilver had existed. In the X-Men universe, what is the difference between an Omega and Alpha mutant? Here's cyclops an alpha , his power opens a portal to another universe that is made of pure kinetic energy.
That gives Quicksilver a speed of 280 +/- 188 kilometers per second (or, if you insist on thinking in miles per second, 174 +/- 117 mps). Yes, that's way faster than the speed of sound, but way slower than the speed of light. That's about the right range of speeds.
Both sides know what they own. They both had the rights to the characters. "Marvel Studios decided to kill of Quicksilver due to Fox having bigger plans for that character, and not confuse the audience with two Quicksilvers in different franchises."
Magneto is not a villain motivated by world domination. He is a man riddled with PTSD, trying to save his family. Imagine you are a child whose loved ones are hated. Your father and mother are then killed because of their race.
History. Magneto was finally pushed too far by Red Skull after the madman turned Genosha into a Concentration Camp and began to exterminate mutants and inhumans - bringing to reality Magneto's greatest fears about the future of humanity and mutants.
While Thanos is an Eternal and has the standard powers of super-strength, agility, regeneration, immortality, and more, Adam Warlock takes the upper hand. He can be killed, but he resurrects to be stronger every time.
It's unknown if Rogue could acquire any of Thanos' strength, given it's innate to him as a Titan, but the secondary effect of her powers could prove Thanos' undoing. Rogue would need aid to get close enough to touch him, but once she is within reach, she could sap Thnaos' lifeforce.
