While there are a lot of creatures in Lumiose, we have no doubt that the Pokémon ZA Kanto starters are among the ones you're more desperate to get your hands on. There's a bit more to these guys than a chance encounter, and we're here to tell you all about it.
Charmander, Bulbasaur, and Squirtle are the very first Pokémon you can get in the original games, maintaining a place in the hearts of trainers worldwide. So let's go over how exactly you can obtain them.
How do I get the Pokémon ZA Kanto starters?
If you want to get Charmander, Squirtle, or Bulbasaur, you need to head to Mable's lab for a side mission; she'll message you shortly after the first time you beat a Rogue Mega Pokémon.

Once there, she lets you choose whether you want the fire-, water-, or grass-type Pokémon. Depending on which Pokémon ZA starter you choose, you may want to opt for a different type. So, if you start with Totodile, you might want to pick Bulbasaur or Charmander to broaden your team.
Don't worry too much about who you choose, though, as you can still complete your Pokédex later on. After you complete the game, you get access to the final Wild Zone, and that's where you can find the three Kanto starters.
