Yes, Pikachu can be shiny in Pokémon Go. The shiny form of Pikachu was released in August 2017, alongside shiny Pichu and shiny Raichu, as part of the Team Go Park event in Yokohama, Japan. As you can see below - or possibly not, which is the problem - shiny Pikachu looks awful. Maybe they were just trying to keep this iconic Pokémon as close to the original as possible, but it smacks of missed opportunity. Looking exclusively at the Kanto line, since that's the one with Pikachonk in it, everything just looks like it has been out at the beach for too long. Sure, this makes sense for Mr Windych
