**Season 3 adds 11 Johto evolution forms to Kanto partner lines.** Complete a form's challenge to unlock it, then choose the form during evolution. The original announcement describes each form as having its own bonus and Ultimate. The challenges below are not a complete objective list: check the current in-game card for the exact condition.

## The 11 Johto forms

| Kanto line | Johto form | Decision point |
| --- | --- | --- |
| Golbat | Crobat | Choose evolution or continue with Maturity from level 44. |
| Gloom | Bellossom | Choose the classic or Johto branch. |
| Poliwhirl | Politoed | Choose the classic or Johto branch. |
| Slowpoke | Slowking | Choose the classic or Johto branch. |
| Onix | Steelix | Choose evolution or continue with Maturity from level 44. |
| Scyther | Scizor | Choose evolution or continue with Maturity from level 44. |
| Seadra | Kingdra | Choose evolution or continue with Maturity from level 44. |
| Porygon | Porygon2 | Choose evolution or continue with Maturity from level 44. |
| Eevee | Espeon or Umbreon | Two more options join the existing branches. |
| Chansey | Blissey | Choose evolution or continue with Maturity from level 44. |

## Unlock the form first

The developer says each new form has a challenge performed with its corresponding partner. Completing the challenge permanently unlocks the choice; the exact objectives can differ. A visible form in the Pokédex does not by itself demonstrate that your account has unlocked it. Read the current challenge, complete it and then check the evolution choice in a later run.

## Choose a branch in a run

When an unlocked branch is available, compare its bonus, Ultimate and how it fits your current attacks. Gloom, Poliwhirl and Slowpoke can choose between their established branch and a Johto form; Eevee adds two new alternatives. Do not read all choices as a fixed evolution sequence. Other eligible lines can choose to keep growing with Maturity or evolve from level 44, as described in the Season 3 announcement.

## Everstone, Maturity and Johto babies

The Everstone costs 400 Stardust in the Shop and is also a Task reward, according to the announcement. With it in the Bag, evolution offers a stay-as-current-form choice and the Pokémon benefits from Maturity. The seven new baby partners can choose not to evolve without an Everstone and receive a stated 12% damage and HP bonus. They retain the baby's kit, passive and Ultimate if they do evolve.

## How this affects builds

A new form's bonus and Ultimate can change the way an established route plays. Recheck the current card before following a Season 2 build or [older tier list](https://pokebonk.co/tier-list), and distinguish an unlocked form from a separately recruited partner. For the new Johto starter choices, see the [Johto starter guide](https://pokebonk.co/guides/johto-starters). The practical value of a branch depends on your run, not only its species name.
