Can you catch more than one Ditto?

Yes, you can catch more than one Ditto in Pokémon games. Ditto can transform into various Pokémon, so when you encounter one, it may disguise itself as a different Pokémon species. Each time you catch a Ditto, it will be registered as a new entry in your Pokédex, allowing you to collect multiple Ditto for different purposes, such as breeding or battling.
