And I don't mean a claimed "reboot" like Black. I mean in the way that would happen if Hell froze over and the head of Nintendo was captured by a UFO while being struck by lightning simultaneously.

If Pokemon was restarted completely from scratch, nothing compatible, all previous Pokemon or regions don't matter anymore (with a completely new roster of maybe not even the same number as a normal region, maybe a couple previous ones return and that's it), what would the first game be like?
