But if you think about it, the first 4 gens are all in Japan, right? So why are Sinnohmons more similar to Unovamons than they are to Kantomons?
And more importantly, Kantomons appear in every region anyway. We think of shit like Pikachu as a Kantomon, but it actually appears everywhere and Kanto is simply the first place we had the dubious honor of seeing it.
