Porygon, the Virtual Pokemon, is a Normal-type Pokemon in Pokemon GO, and one of the hardest Pokemon to evolve. To evolve Porygon, Trainers will need two special evolution items and lots of Candy.
Currently, the Ultra Unlock 2021: Time event is underway, and Porygon is spawning more frequently in the wild. Therefore, it's no surprise that Trainers are looking to evolve their Porygon that they've saved up some Candy for. Here's a guide explaining how to evolve Porygon.
How to Evolve Porygon in Pokemon GO
Porygon has two evolutions: Porygon2 and Porygon-Z. Porygon needs an Upgrade and 25 Porygon Candy to evolve into Porygon2, then a Sinnoh Stone and another 100 Porygon Candy to evolve into Porygon-Z. This makes Porygon one of the harder Pokemon to evolve in Pokemon GO.
Luckily, evolving Porygon into Porygon2 is quite easy right now because of the Ultra Unlock event. On Step 4 of the Ultra Unlock 2021: Time Timed Research, you'll come across the task "Catch 7 Porygon," which will reward you with an Upgrade. You can then use the Upgrade and the candy you earned to evolve Porygon. This Timed Research will only last until Aug. 3, at 8:00 pm local time, so make sure you complete that task while you still can.
If you missed that task, you can also obtain Upgrades by spinning PokeStops. There's a 1% chance that an evolution item will drop from a PokeStop, and you'll be guaranteed an evolution item on your seventh-day "First PokeStop of the Day" streak.
Evolving Porygon2 into Porygon-Z is a bit trickier. Not only do you need a lot more candy, you'll need a Sinnoh Stone. There are a few ways of getting a Sinnoh Stone:
- Chance of dropping when you collect your seven-day Research Breakthrough reward
- Receive one by defeating a Team GO Rocket Leader
- Chance of dropping from a PvP Trainer Battle
- Possible "Mystery Item" reward in the GO Battle League
Any of these methods might get you a Sinnoh Stone, so be patient and catch lots of Porygon to save up candy. You'll be able to evolve your Porygon fully in no time.
