>>32138816Much like the teleporters from Star Trek, a Pokemon that goes into a Poke Ball is disintegrated cell by cell. The make up and position of each cell relative to every other cell in the creature is read and stored as data, then reassembled when the Pokemon is "called out".
Essentially, you're killing any Pokemon you put in a ball, and then recreating an exact copy of it on the spot when you want to use it again.
