Right. And the Slowbro and Shellder. Or that Gengar is the shadow of Clefairy. (Actually like that theory)
Haha, my sig is basically just a combination of all the weird theories about Poke'mon. I doo like some of them, though. The point is, though, people need to realize that Poke'mon isn't real, and sometimes there isn't actually an explanation for things. It's a cartoon. An awesome one! But a cartoon, nonetheless.
Zelda lore and theories are much more in depth.
