While early Jean Gray seems to be a simple telepath, her use of the Phoenix Force would turn her into the most powerful member of the X-Men and the most powerful mutant Marvel has ever introduced. As Phoenix, Jean Gray can fly, make force fields, and control other mutants.
The Legion, who Magik called "The God Mutant," appeared and altered reality to wipe the Elder Gods from existence and reset the world to a time before they had manifested.
Class 5 or Omega mutants is a category reserved for the elite of the mutant community, blessed with unlimited genetic potential. For a long time there was only Jean Grey, the first, however over the last couple of decades many more have sprung up or been reclassified.
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.
Cyclops' brother, Havok, is one of the few Marvel superheroes who can defeat the Hulk in a fair fight. Alex Summers aka Havok may not be as popular as his more famous brother, but he is easily one of the most powerful mutants in the Marvel Universe.
The results shown presented the following as Alpha-Level Mutants: Franklin Richards, Phoenix, Legion, Professor X, Storm, Namor, Sebastian Shaw, Havok, and Sinister (though he was not classified a mutant at the time).
Deadpool's not a mutant. His powers come from experiments carried out by the Canadian military, not from a mutant X-Gene. What makes it a little confusing is that the experiments were attempts to duplicate Wolverine's powers, so while he's not a mutant himself, his healing factor is derived from mutant biology.
In some cases, a mutant might fall under two different classifications if they have multiple powersets. Wolverine's enhanced senses are a Beta Level powerset, while his healing factor makes him an Alpha Level Mutant. In these situations, the mutant is classified based on whichever powerset is the strongest.
Selene is the oldest known human mutant. Functionally immortal, her millennia-long life is attributed to her ability to drain the life essence from other beings to extend her own existence indefinitely. Her name derives from the ancient lunar goddess Selene, daughter of the Titans Hyperion and Theia.
Summary. X-Men's most powerful mutants are described as Omega level, but some go beyond even that. Matthew Malloy, Franklin Richards and Vulcan were all explicitly termed beyond Omega. The mysterious mutant Miranda gave this type of mutant their own term, with Beast defining once-in-a-lifetime power as 'Omicron level.'
Wolverine is certainly not an Omega-level claw-wielder. With just three Adamantium-coated claws, he doesn't have the offensive and defensive capabilities of most Omegas. He doesn't even have Adamantium claws on his feet, the way that X-23 does. What Wolverine does have Omega-level capabilities in is healing.
The Juggernaut appears in X-Men: The Last Stand, portrayed by Vinnie Jones. This version is a mutant with the inability to be halted once he starts running and superhuman strength sufficient to fight Wolverine to a standstill and possesses no explicit connection to Charles Xavier or the Gem of Cyttorak.
Sinister is one of the X-Men's most dangerous enemies. The mad scientist, Nathaniel Essex, is best known by the name Mister Sinister. After cutting a deal with Apocalypse, Essex was transformed and given the ability to become essentially immortal.
At this time, Thor's father is Odin and his mother is Firehair (one of the first mutants and host of the Phoenix force). So, he would technically be half-asgardian and half-mutant.
Jesus healed a blind man, a leper, a paralytic, and others—an ability that Exodus himself has demonstrated. With this many distinct powers in one person, if Jesus was a mutant, he was an Omega-level mutant rivaling Jean Grey and others.
According to present X-Men continuity, there are currently 25 Omega-level mutants: Monarch, Iceman, Elixir, Jean Grey, Legion, Magneto, Proteus, Mister M, Storm, Exodus, Quentin Quire, Vulcan, Hope Summers, and the recently-introduced Krakoan mutants Isca the Unbeaten, Tarn the Uncaring, Idyl, Genesis, Redroot, the ...
The difference between Beta Mutants and Alpha Mutants is that the Beta Mutants have flaws, albeit very small flaws. The Beta mutants are also believed to be about 10% of the mutant population. Some examples of Beta mutants are Beast, Angel, Wolverine, Mystique and Sabretooth.
Wanda ceased to be a mutant in Earth-616 in a controversial Marvel Comics retcon, but in this reality, she was considered an Omega-Level Mutant capable of telekinesis, telepathy, and more.
In the comics, there's a pretty sharp delineation between mutants and other superpowered being known as mutates. Human mutates are people like Spider-Man, the Hulk, or Captain America, whose superhuman abilities are artificially created; whether through the use of super-soldier serums or exposure to radiation.
Mystique's powers are revealed to be just short of an Omega-level mutant, and she has the potential to surpass her last limitation and become a god. Mystique is Nightcrawler's father, not Azazel, and her control over her cellular and genetic structure is instinctive.
While early Jean Gray seems to be a simple telepath, her use of the Phoenix Force would turn her into the most powerful member of the X-Men and the most powerful mutant Marvel has ever introduced. As Phoenix, Jean Gray can fly, make force fields, and control other mutants.
There are different classifications of mutants, based on their power levels, appearances, and ability to physically integrate into societies. An Alpha mutant, for example, is a person who has full control over their mutant abilities, but is often mistaken for a regular human being when their powers aren't in use.
