Pokemon Go - How to Get Pikachu
  1. When you first start the game you will see Bulbasaur, Charmander and Squirtle near your Trainer, instead of tapping on one of these three, walk away from them.
     
  2. Keep walking away from them and you will see that they disappear and then reappear near your Trainer.  Do this 4 times.
     
  3. Continue walking and the 5th time Pikachu will pop up on the screen along with the other three Pokémon.
     
  4. Tap on Pikachu and throw a Pokéball to capture it.
     
  5. Congratulations you now have started the game with a Pikachu!
