From the size of a worm to the size of a bulldozer, a Pokeball captures all Pokemon in a beam of light and stows them in what looks like an iPrison for easy transport.
As far as we know, Pokemon, much like everything else, are made of matter. If a Pokeball can condense and stow a living being without harm, that changes the whole world. Even if we’re limiting ourselves to purely organic matter for some reason – putting aside the Pokemon made of rock, or metal, or pure unmitigated terror – the implications of Pokeball technology are huge. Never mind the easy stuff, like food and livestock storage – long distance travel would be a breeze: just pack a whole plane full of people in a rucksack. Unless Pokeballs are fun-size existential boredom hells, living things in the ball aren’t aware of the time passing. Imagine a world without smelling airplane farts. Truly, that is the definition of utopia.
