I know we're used to characters being treated as walking powersets with one or two characteristics slapped on top but consider this: its not realistic that every mutant is standing ready in case of an attack 24/7. Maybe Apocalypse is in otherworld. Maybe Exodus is at the salon getting his locks done. Maybe Magneto is getting a mani pedi. And the Marauders are sleeping off after drinking all the way from Russia to Krakoa. The whole point of Krakoa was that they wouldnt have to be constantly on defcon 1. Not to talk abt the size of the island.
