How to get it
- Spin PokéStops and Gyms for a chance at a standard evolution item.
- The seventh consecutive daily PokéStop spin awards an evolution item, but does not let you choose this one.
- Research and events can award it explicitly.
How to use it
- Open the Pokémon’s details and choose the evolution button showing this item.
- Check the target and Candy cost, then confirm. The item and Candy are consumed together.
Worth knowing
The next evolution, Porygon2 to Porygon-Z, needs a Sinnoh Stone and 100 Candy. A second Upgrade cannot substitute for that stone.
An evolution item does not improve IVs. Choose the individual Pokémon you want to keep before spending it.
Compatible evolutions
Candy costs are for the relevant Pokémon family and show standard, undiscounted amounts. Regional forms can have different requirements.
| From | To | Candy |
|---|---|---|
| Porygon | Porygon2 | 25 |
