How to get Pikachu as your starter Pokémon

  1. Sign up for a Pokémon Go account.
  2. Make your avatar.
  3. When the Professor prompts you to "Catch a Pokémon," walk away from Bulbasaur, Squirtle, and Charmander.
  4. If you walk far enough away, the trio will respawn and your phone will vibrate. (We recommend walking along a sidewalk in your neighborhood to trigger this.)
  5. Repeat step 4 3-5 more times, and a fourth Pokémon will appear: Pikachu!
NOTE: Polygon managed to make Pikachu appear after just 4 respawns, but it took me 5 to make this happen. Your mileage may vary.
Even if you already have an active Pokémon Go account and missed out on this hack, you're not out of luck on catching Pikachu — all of the starter Pokémon, even the hidden ones, are available for capture around the world.
