>>50534148>If Pokerus is a Pokemon, why can't I catch it in a pokeball?You can. It gets contained in the Poke Ball alongside with the Pokemon it's attached to. But it's too microscopic to be identified and caught as its own Pokemon separate from the host.
>If humans are a Pokemon, why can't I catch them in a pokeball?Because Poke Balls don't recognize them as Pokemon due to the different readings they give, much like an Ultra Beast bathed in the energies of Ultra Space or the incompatible readings of Zygarde's Cells and Core.
But if you took the time to develop a Poke Ball that specifically focused on the readings a human gave off, I guarantee you that it would work, and that line of thought is basically the very premise of one of Pokestar Studios' movies, a future where Pokemon have learned how to capture humans.
