Undoubtedly, Magneto could overpower Jean Grey without the Phoenix Force. Jean Grey's telepathic abilities are completely null and void against Magneto, but he would not be unaware of her attempts to reach out.
1 Cyclops Has Always Known How To Beat Jean
Cyclops got the drop on Jean and hit her with a full power optic blast, taking her down.
Magneto is able to move and manipulate metals (through electromagnetism), but Jean Grey can move and manipulate anything.
In Mark Waid's History of the Marvel Universe #3, Marvel has finally officially revealed who the most powerful mutant in the universe is. And no, it's not Wolverine, Jean Grey or Professor X. It's Marvel's Franklin Benjamin Richards.
Jean Grey was the only Class Five mutant ever met by Charles Xavier (which implies Magneto and Pyro are Class Four), and her potential was stated to be limitless. It is unknown if Callisto counted herself and the Omega Gang as Class Three or less, or among the Class Four.
Grey, even without the Phoenix Force, is the most powerful mutant in the Marvel universe. Unlike Professor X, her powers go beyond telepathy and extend to telekinetic and psionic powers. Her telepathic, telekinetic, and psionic powers, have virtually no limit.
The nearly fleshless Wolverine jumps up and stabs his claws into Magneto's chest, mortally wounding him. Magneto rips the Adamantium from Wolverine's bones, killing Wolverine, leaving just a severely charred skeleton and an arm of flesh due to his healing factor not working.
Weaknesses. Initially, Jean's limited power made her vulnerable to a variety of skilled and/or powerful opponents. Dissociative Identity Disorder: As "Phoenix", her main vulnerability was that if she became emotionally unstable, she would lose control of her powers.
After all, Magneto is the master of magnetism, able to control metal with his mutant abilities. Iron Man is a character who is completely dependent on his technology, crafted from his metal-based tech. In theory, Magneto could just clench his fist and implode the suit through Tony's ribs.
She took down the Dark Phoenix
Scarlet Witch has the ability to resist the Phoenix Force and can cause pain to its hosts. When Cyclops killed Professor X, he took on the persona of the Dark Phoenix, forcing Wanda and Hope Summers to join their powers and take him down.
Jean Grey would win this battle easily and without lifting a finger. All she needs is her telepathy. Martian Manhunter may have struggled to control Black Adam, but he's not Jean Grey. Her control over a person's mind is vastly more powerful than his.
Scarlet Witch is indeed powerful and has overpowered magical abilities that make her a threat in both the comics and the MCU. But the thing is that Dark Phoenix is a threat to the entire universe as her powers are cosmic-level. In that regard, it is easy to see why Dark Phoenix is the more powerful character.
Iceman is one of the most powerful mutants on the planet. While he doesn't do much solo work, he has battled Magneto many times with the X-Men, and he's come out on top every time.
Powers and abilities. Jean Grey is an Omega-level mutant, and at her highest and strongest potential was fully merged with the Phoenix Force and with it was able to defeat even Galactus.
This is a very easy question and the answer is: Yes, she can. Magneto is a mutant who has the ability to generate and control magnetic fields. Wanda is a nexus being and chaos magic user. Her abilities exceed Magneto's in all cases.
Jean Grey is a rarely powerful psychic in that she has dual abilities: both telepathy and telekinesis. It is this potent blend that gives her so much power, as she can control and manipulate everything around her, be it invisible brain waves or the physical world.
Jean Grey's greatest fear is that loss of control. She's constantly proven that she won't lose control, but that doesn't change her fear of that moment. She's afraid that it can happen to her, that she can break like they did and become a villain that her friends have to defeat or die trying.
Jean Grey is easily one of the most powerful mutants on the planet. Her vast telepathic and telekinetic abilities make her a force to reckoned with. Wonder Woman is a titan of physical power, but Jean's mental might would be a bit too much for her. Wonder Woman is extremely limited in what she can do against Jean.
Yes. To have the hammer in his hand wouldn't and shouldn't ever happen. He's just not worthy of it under the magical conditions set on the hammer as per Odin The Asgardian All-Father. However, his genetic power and ability to control metal and magnetic fields would give him a leg up in countering its power.
There is a Wakandan isotope and an Antarctic isotope, and both of them are completely unaffected by Magneto's powers. Most notably, Magneto cannot affect Captain America's vibranium shield, and he cannot affect Black Panther's suit.
1 Iron Man Has Paradoxically Been Able To Beat Magneto
This should allow Magneto to make short work of Iron Man but Iron Man has modified his armor so Magneto's powers wouldn't work against him.
Hercules / Zeus
In fact, he is considered by many authorities to be the physically strongest character Marvel has ever created. According to legend, he replaced Atlas in holding the sky on his shoulders.
Fictional character biography. Selene is the oldest known human mutant.
An Omega-level mutant is one with the most powerful genetic potential of their mutant abilities. The term was first seen in the 1986 issue Uncanny X-Men #208 as "Class Omega", but was completely unexplained beyond the obvious implication of it referring to an exceptional level of power.
