Some Pokemon can change form without evolving, using items or abilities. These form changes affect types, stats, and appearance but are not part of the evolution chain.

## Examples

- **Oricorio**: Changes form (Baile/Pom-Pom/Pa'u/Sensu) by using nectar items from different islands. Each form has a different type (Fire, Electric, Psychic, Ghost + Flying).
- **Darmanitan**: Has a Zen Mode ability that changes it to Darmanitan (Zen) in battle (Fire/Psychic). Galarian Darmanitan Zen Mode is Ice/Fire.
- **Rotom**: Changes form by interacting with appliances (Heat/Wash/Frost/Fan/Mow), each with different secondary types.
- **Shaymin**: Changes between Land and Sky forme using the Gracidea flower.
- **Tornadus/Thundurus/Landorus**: Incarnate vs Therian forms via the Reveal Glass.
- **Hoopa**: Confined vs Unbound via the Prison Bottle.

## Scope

This is lower priority than basic form support (bean f44d) and submodule update (bean 6aje). It matters for tracking because a player might catch an Oricorio in one form and change it to another — the tracker should reflect the current form's types.

## Design considerations

- Should the tracker allow manually changing a caught Pokemon's form?
- Or should it just track the form as encountered and leave it static?
- How to represent form-change items/methods in the data model?
- This may not need seed data support — could be a manual UI action on a caught Pokemon
