Post any of your theories about Pokemon - whether they be legendary, common, insane or logical!

One that I have personally is pretty obvious, and I'm sure hundreds of people have already thought about it. But the three Pokemon that perished in the fire in Ecruteak that Ho-Oh brought back to life as the three legendary beasts were, originally, Vaporeon, Flareon and Jolteon.

Also lots of people wonder why in the games Voltorbs are put in the place of item balls when Voltorbs are supposed to be much larger than Pokeballs... well, I read somewhere that they may have been a byproduct of the first attempts at mass-producing Pokeballs, so if that's true wouldn't it make sense for them to be able to shrink just like the Pokeballs are able to do in the anime?

And I think that's all I've got for now >.>
