I don’t think so, but it’s the only Pokémon introduced through Pokémon GO. This directly explains its inclusion in the Pokémon GO set (and the theme deck from said set), but it also makes it the only Pokémon that Pokémon GO fans can cherish as their own in the same way that, say, one of the first players to experience Sinnoh can cherish Garchomp as their own.
I just realized a couple of days ago that Let’s Go Eevee (You’ll want to hear this,
@PMJ, I saw you saying Let’s Go was S-tier) is a reference to four different Pokémon stories: Pokémon Red and Green/Blue, Pokémon The Series (through recurring Pokémon Yellow Version content), Pokémon Adventures (through the three postgame trainers), and Pokémon GO! And yet it goes on to reference even MORE Pokémon games with Mina (and all the Alolan forms) from Sun and Moon making appearance and Mega Evolution returning. Combine this with all new characters like the protagonist, rival, Mr. Dazzling (the move deleter’s alter ego) and The Rocket Sisters (who inexplicably replace The Rocket Brothers), the brand new GO Park (which admittedly falls under the Pokémon GO reference category), and references to Pokémon Quest in the Celadon Game Corner, and you have quite a lineup of source material, easter eggs, and original cameos!
