My 2 cents on travel powers:
Take whichever one you want. Explaining it away, is of course, on you...but since the origens are all single-cast, I feel there's some wiggle room.
Cable is a mutant. I'd use Mutant as his origen. However, his principle form of transportation for most of his early career was contacting his Orbital Satelite and saying "Bodyslide by one," and teleporting. Just saying, though his teleporting was becasue of technology, he's still a mutant.
It's also not completely unreasonable, especially on Virtue or RP based communites (where this whole thing is pretty much implied towards anyways) to simply default to "magic shoes. They were a gift." Or "Legion Flight Ring." Or...spring boots...or something.
The point is, as long as you're patient enough to explain yourself again. And again. And Again. It's all gravy.
