The amazing researchers on TheSilphRoad have reported that Pikachu starts of as a regular Buddy Pokemon that stands next to you, but after you walk 10 KM with it, it turns into a Shoulder Buddy! 🙂

A sweet addition to the Buddy System indeed, but only Cosmetic. Pikachu doesn’t get stronger, it doesn’t evolve into Raichu and it certainly doesn’t battle a flock of Sparrows. Maybe in the next patch!
