As of now, Pokemon GO features hundreds of catchable monsters, but fans haven't forgotten their older favorites. One of these pocket monsters is the iconic Porygon. This Normal-type Pokemon made its appearance in Gen 1's Kanto region and has become a sight to behold thanks to its more digitial appearance as opposed to the more "organic" looking critters.There are two evolutions for Porygon, both of which require an evolution item to enable its transformation. This includes the Up-Grade and here's how to get it.Guide to evolving Porygon using the Up-Grade item in Pokemon GOT-Squared the PokeHunter@TSquaredKSShiny Pokemon #43 for 2022 is Porygon.

Here are the stats for Porygon and Porygon2 for those wondering if the upgrade is worth it:PorygonType: NormalCP range: 20 - 1720HP range: 15 - 140Attack: 153Defense: 136Stamina: 163Porygon2:Type: NormalCP range: 33 - 2711HP range: 18 - 168Attack: 198Defense: 180Stamina: 198a.@foxalbiazulOne bad-ass Up-Grade!!#PokemonGO10One bad-ass Up-Grade!!#PokemonGO https://t.co/KMFQxwATG2Players will need to feed their monster 25 Porygon candies and one Up-Grade to get Porygon 2. Overall, players should gear up for a bit of grinding. For those low on candies, make sure you go on walks to get more for your Porygon until you have reached the needed amount. Additionally, catching more Porygons works too.Evolving, on the other hand, requires evolution items, which are rarely handed out. There is a very small chance that they can be obtained by spinning the Photo Disc in PokeStops and Gyms. However, there is one guaranteed way to get them. Spinning these discs each day until the end of the week will grant one of the seven evolution items on the seventh day spin streak.

It was produced by Silph Co.While the details mention "certain species," the Up-Grade is only usable on Porygon. These evolution items can also be obtained as rewards from research tasks and gifts. Among these, the Sinnoh Stone will allow evolving Porygon 2 into Porygon Z, the final form in its evolutionary line. This also requires 100 candies on top of the necessary item. As the name suggests, Porygon-Z was introduced in Gen 4 which takes place in the Sinnoh region. It's description states:A special stone originally found in the Sinnoh region that can make certain species of Pokemon evolve. It is very tough and has a beautiful sheen.Raven Wizard 💎 #UnleashTheDragon@BLRavenWizardMy Shiny Porygon Family! 🥰🥰🥰Note: They are transferred from Pokemon GO! :D#PokemonLegendsArceus #ShinyPokemon51My Shiny Porygon Family! 🥰🥰🥰Note: They are transferred from Pokemon GO! :D#PokemonLegendsArceus #ShinyPokemon https://t.co/OokeznRB7sAll three Pokemon can be transferred to traditional Pokemon games like Pokemon Legends: Arceus for the Nintendo Switch.
