I think they're thinking Omega level mutants and that kind of thing.

Pretty sure she hasn't really reached that point yet though.

Maybe Gamma level?

Lots of powers, with few limitations.

That wouldn't fit the classifications. Aside from slight moments, she can keep her appearance under control. Like, this was more a problem with her comic counterpart which I would qualify for gamma level. However she does have limitations, her appearance is human, and compared to past iterations, Kamala is generally pretty good at controlling her abilities in precise ways.

I think the OP might mean what power level, like in the X-Men movies there was a mutant who could sense other people’s powers and power levels, like how she said Jean is level 5, Magneto is level 4, and the other people in the building are level 3 and under. If that’s the case then I think Ms. Marvel is maybe level 3, but I’m not sure.
