my favorite fics are the ones that really grapple with the extent of his power

Yes, yes, a thousand times yes! With a side of BAMF in his own inimitable way, and being underestimated (as close to bullet proof as I get). Visually, I'm in love with Charles's response to Jean's attack in the final movie, but I feel deeply that it should have led to something, and it does not (did I miss it?) It isn't even clear what Magneto takes away from it. Bad director! Bad!
