no i refuse, pokemon are not digimon! i prefer the similar concept of energy conversion. Pokemon can leave the pokeballs at will, thus normally, if you don't have a strong ball, you need to weaken it first. early versions of the manga that follows the adventures of Red and Gold, it depicts pokeballsa s slightly see through, and the pokemon is actually minimized into the ball, thus trainers know what pokeball they're throwing, and can even communicate with thee pokemon from the ball.
