As part of the leaks circulating, there’s an image of a player walking with around the map with a Charmander at their side. This image, unfortunately, was confirmed to be a fake — but it seems that the information suggested by the fabricated image may be real.

Again, while this hasn’t yet been confirmed, it’s been suggested that you might be able to get a Charmander as a gift Pokémon, so long as you have save files from one of the other Pokémon games available for the Switch.
