Start off with Pikachu
As the series started with Pokémon Red and Blue back in the day, you begin your journey having to choose among Bulbasaur, Charmander, and Squirtle as your first Pokémon. Pikachu ain't in there.
But as Polygon details, there's a secret way to start out with the lil electric rodent that doesn't involve waiting for Pokémon Go Yellow: just ignore the other three. If you ignore the trio four times, they'll reappear with Pikachu to make it a quartet. Though to be honest, they make a lot better gym battlers than they do musicians.
Anyway, it apparently takes a while to catch Pikachu compared to the others. But let's be real: you're playing a game on your phone. Your productivity has likely already plummeted.
