I was wondering why is there a limit?

Why does everyone follow it in the anime?

Even Team Rocket follows it, even though they are a criminal organization that steals trainers' Pokemon. Just because there is a custom in place, doesn't mean people have to follow it.

Is it discussed or shown in the anime?

    The limit only goes for competitions. Read chapter 9 again. You can see how Red is carrying many Pokemon, as he has no place to store them, until he meets Bill and introduces him to his transporter. Commented Jan 24, 2016 at 16:09

    Could be a feature that carried over as a result of constraints (or possibly just a design decision) from the video games. I don't have any evidence for this, but it's possible Nintendo (GameFreak / etc.) decided on six slots for (perhaps) the sake of balance or "learnability" in the games, and that just carried over into the show.

The Pokémon anime is actually a little inconsistent in this. In episode 11: Charmander – The Stray Pokémon, Damian bragged about his collection of Pokémon and there was a large number of Pokéballs (more than six) in front of him. In episode 13: Mystery at the Lighthouse where Ash caught his Krabby, Misty told Ash that he could only have six Pokémon, and any more he caught after that would be sent back to whomever gave him his Pokédex.

Speculation: So, maybe if you have a Pokedex it forces you to only keep six Pokemon and people without one don't have to follow the rules?

Why Does Pokémon have a Six Pokémon limit?

In early episodes, Ash talks about the rules of Pokémon battles that the Pokémon League set. For example, he tells Team Rocket it is against the rules to use two Pokémon at once. Presumably the six Pokémon limit is one of these rules. Most trainers will probably follow the six Pokémon limit because of the Pokémon League's rules, but it isn't clear why the bad guys would follow the rules. And in the anime, as evidenced by Damian, it isn't clear whether they do follow that rule.

Edit: In Pokémon: Black and White, catching a seventh Pokémon works differently than it did when Ash caught his Krabby. Rather than being transported back to a professor, the Poké Ball shrinks and won't open and Ash has to get to a Pokémon Center to transfer his Pokémon. This inconsistency is first seen when Ash catches a Sewaddle in Sewaddle and Burgh in Pinwheel Forest! and is seen again when Ash catches a Palpitoad in a later episode.


Not from the anime, but the manga does suggest an answer in Volume 10 of the Pokemon Adventures series (in the Gold&Silver arc).

Professor Oak explains to Professor Elm why there is a six-Pokemon limit.

Professor Oak: Of course it's possible to carry seven or eight Pokemon - even twenty or thirty, if for some reason you must. But how could one trainer give that many Pokemon enough individual love and attention? Only we researchers can justify big collections. Among trainers, anyone who uses over six is disparaged.

Professor Elm: Of course ...

Professor Oak: Which is why the Pokemon league decreed 6-to-1 as the ideal Pokemon-to-trainer ratio. It's the perfect balance for a serious trainer. And Crystal is clearly serious!


Maybe it's a part of humanity towards the Pokemons. Like when a trainer has too may Pokemons with him, he has to feed all of them, train all of them, and care for all of them. This may prove to be a hindrance. Also the Pokemons would keep fighting for their Trainer's attention. So the authorities must have added this rule so that it is easy for both the Trainer and his Pokemons.

About Team Rocket, maybe they were never able to catch more Pokemons.
