If the world of Pokemon existed, Pokemon would unlikely be called "Pokemon", and the people's main preoccupation would unlikely be about Pokemon fights.

When we look at the world of Pokemon carefully, we would soon realize that the main difference between the Pokemon world and our world is due the amazing contraption called the Pokeball. When a Pokeball is thrown at any object, it would store that object into itself, while the mass and weight of the object completely disappears.

So in the Pokemon world, a Pokemon is basically... just any creature that can be found in the wild, and Pokemon trainers are people who bother to put them into Pokeballs. The word "Pokemon" supposedly stands for "pocket monster", but the thing is, those creatures are capable of being fitted into pockets only because of this invention called "Pokeball", and not due to any special characteristic of their own. It's as lame as calling all animals CageAnimals or all water BottleWater, just because they can be stored in cages or bottles respectively.

In the world of Pokemon, energy is not conserved. If you lift up a Pokeball with an Onix, then release the Onix at the top, store the Onix back into the Pokeball and repeat, you'll get a free energy generator. If anyone can ever invent something like a Pokeball, the world would probably be consuming energy without giving two hoots about oil prices and global warming. A world unbound by energy constraints seems pretty good.

Warfare would be damn different with Pokeballs. If timed bombs explode in Pokeballs, then people would be able to carry unlimited amounts of ordnance, so you could pretty much have a Tsar bomb hidden in a purse. If they don't, then the whole world is pretty much immune to nukes, considering that Pokeballs are damn cheap.

No matter how powerful your armoured weapons are, you have to be wary of MGs that fire Pokeballs 'cos it's instant KO for anything to get hit by it.

If two Pokeballs hit each other, and one of them enters the other, how would you know which Pokeball entered which Pokeball?

A war would only involve Commandoes bringing an entire army of Pokeballs into the enemy capital.

As I think more and more about it, Pokeballs sound like damn frigging imba things to have.
