Q&A for How to Evolve Porygon

After receiving the National Pokédex, you can talk to the man living at the mansion with the Trophy Garden. If he mentions Porygon, you may find and catch a Porygon in his garden afterwards.

To evolve Porygon, you first need the Up-Grade, which you can obtain from an NPC in Aether House. This item allows Porygon to evolve into Porygon2. For its final evolution, Porygon-Z, you will also need the Dubious Disc, which you can acquire from Faba after defeating him at Aether Paradise in the post-game.

You should try to find other Pokémon players. Consider reaching out to those who may also need assistance with trades, as they are often more willing to help.

To evolve Porygon, you must trade it while it holds the Up-Grade, then trade Porygon2 (its evolution) while it holds the Dubious Disc.

You can't catch either of them in the wild; you have to evolve a Porygon or trade for them.

Both the Up-Grade and the Dubious Disc can be found in the Battle Maison for 32 Battle Points.

You can obtain Lunala in Pokémon Moon by evolving a Cosmog into Cosmoem, which then evolves into Lunala. Alternatively, progress through the story until you receive the Moon Flute and summon Lunala with Lillie.

You can obtain the Upgrade, like other evolutionary items, randomly from PokéStops, though it is a rare find.

You cannot find Porygon in Pokémon X. You must transfer it from another game.
