Alternatively, I have always thought of pokemon as "digital monsters" as they are stored in pokeballs as beams of light (you can see mirrors inside balls in the anime too) and they're stored in a computer network. The computer network idea is contradicted in the anime though, as Ash's pokemon are seen being teleported to the professor's lab but being sent through phone lines (like most internet in the 90s) makes for a good argument in favor of being digial
