In Episode 13 Ash catches a Pokémon that would exceed the limit of 6 Pokémon for the first time and therefore it gets transfered automatically to professor Oak. How does this work?

  • How does the ball know it's the 7th?
  • How does it know it needs to transferred to Oak?

If I were to guess I would think that every Pokéball is linked directly to the Pokédex which is linked to Professor Oak or something. But this doesn't make sense in a lot of ways. Because:

  • not every trainer has a Pokédex
  • not every trainer is linked to some professor (I think)

Also what would happen if Ash physically went to Oak, grab some of his Pokéballs (with Pokémon) and walked out?

There is an explanation on Bulbapedia:

Poké Balls are able to communicate with a Trainer's Pokédex, as the system updates itself with information on newly-caught Pokémon, and keeps track of how many Pokémon the Trainer has with them. If a Trainer catches a new Pokémon with the full six already with them, the Pokédex will automatically send the newly-caught Pokémon in its Poké Ball to the Pokémon Storage System that the Trainer is using.
