Since the release of Pokemon GO in 2016, fans have eagerly awaited the slow addition of Pokemon across various Generations in this mobile Pokemon experience, with 2022 finally being the year when players could enjoy the likes of Turtwig, Chimchar, and Piplup alongside the rest of their Gen 4 companions from Pokemon Diamond, Black, and Pearl. Interestingly enough, fans and Gen 4 loyalists who want to complete their slate of Generation 4 Pokemon should also consider getting Shieldon, the iconic Fossil Pokemon with a shield-looking guard around its head.
