The implication that some might have tech-based versions of classic X-powers, is interesting.

Apocalypse, creators of Angel's metal wings, already lives on Krakoa, so that's no big. But a visor that can open a hole to the punch dimension? That'd be a fun toy. And one that can access the brimstone dimension that Kurt uses to teleport? Seems like it could be a bad idea, given that some nasty stuff has been locked away there (including Azazel, for a time). Both sorts of devices might end up weakening barriers between worlds, in some techno-babble way, and end up having to be abandoned, or adjusted somehow, after some shenanigans related to them result, such as random 'holes' to the punch or brimstone dimensions opening up and refusing to close, flooding the area with 'punch' energy, or clouds of black smoke and hordes of prankish whiskey-stealing Bamfs. (Or something far more serious, and less fun, like, "Krakoa just fell into the Brimstone Dimension, and boy, is *it* pissed...")
