How do I catch a Ditto?
Ditto has now been released in the latest patch, and I would like to catch one.
What are the conditions to capture a Ditto? Does it show up on the nearby tracker? Or will it transform into something?
First of all, you won't just see a Ditto on your list of close Pokémon that you can catch. Ditto will first appear in your game as just a regular Pokémon. After catching the Pokémon, it might transform back into a Ditto, and it will then be added to your Pokédex. So you won't know it's a Ditto before that point. You can see an example in the video here.
As for now, the current list of Pokemon which can hide a Ditto is pictured below. So just keep catching those, and you might end up with a Ditto.
Also note that if you get a Ditto after catching a specific Pokémon near you, anyone catching this exact same Pokémon will also get the Ditto.
