I showed you a scan of her using her power in bishop's brain telepathically and she was able to use her powers in the astral plane, as well as the other xmen:
Astral plane shooting bolts of lightning:
generating bolts of lightning in limbo:
trion dimension
she was divorced from the natural world in all these showings. unless you are arguing weather was in these dimensions/realms then I think you have conceded your point. none of those dimensions are natural as you keeping pointing out that she needs to be immersed in to use her powers. nevertheless, my arguments have nothing to do with what I like or dislike but everything to do with what has occurred in canon. external sources being required to use her power is something you have made up.
sn: I think limbo would be the closest thing to hell (not astral plane)and her powers were able to work there just fine.
he didn't have to explicitlystate this because it was shown her powers dont operate how you keep claiming. see above. her powers have worked in the trion dimension, in limbo, on the astral plane and all of those dimensions are not natural. and there is a thing called wis/pis. I'm sure you are aware of this.
