Certain mutants have been confirmed Omega-level status which include:
(I'm sure I might missed a few, but if you know any other please confirm them. Thanks..)
Some abilities portrayed by mutants described as Omega-level include immortality, extreme manipulation of matter and energy...high level of psionic ability...strong or extremely versatile telekinetic, or the potential to exist beyond the boundaries of the known physical universe.
Magneto's control over magnetism...Prof-X's mental telephatic are two examples of this type of capacity. Nonetheless...neither Prof-X nor Magneto's potentials have been established as Omega-level. On the other hand...when their two powers were combined as Onslaught, they were simply the most powerful human entity on Earth to have ever existed (remember that?). I guess neither Magneto or Prof-X allowed anyone to find out the limits of their powers. Apparently Magneto (according to the wiki) can also create force fields, create teleportation wormholes, rearrange matter on the atomic level, warp light to make himself invisible. With those combined with his advanced TK metal powers I thought that makes him a pretty potent mutant. So...why isn't he considered to be at an Omega-level status? Isn't magnetism one of the four fundamental forces? In the comics, at least, his power is not just controlling metal...it's controlling electromagnetic force. Magneto is the most powerful telekinetic character in Marvel...I believe. Ok...he might be pretty god d..m powerful and he might not be Omega-level, but he can surely beat Omega levels since he knows just how to use his power to benefit him...in my opinion.
I'm I right? Does this make sense? Can this be possible? Can all this be determined by the writers? Ain't he's powerful enough to destroy the Earth? Who can really explain the different between powerful and Omega-level? I'm just confuse...
