Ogerpon

Ogerpon (Japanese: オーガポン Ogerpon) is a Grass-type Legendary Pokémon introduced during Generation IX, in The Teal Mask. While it is not known to evolve into or from any other Pokémon, Ogerpon has four forms which are determined by the mask it is wearing. Each mask changes its type and comes with its own unique Terastallized state. While Ogerpon is wearing the Teal Mask by default, it is in its Teal Mask form, and is a pure Grass-type (regardless of whether it is in the Terastallized state or not). While Ogerpon is wearing the Wellspring Mask, it is in its Wellspring Mask form, and is dual-type Grass/Water normally, becoming pure Water-type in its Terastallized state. While Ogerpon is wearing the Hearthflame Mask, it is in its Hearthflame Mask form, and is dual-type Grass/Fire normally, becoming pure Fire-type in its Terastallized state. While Ogerpon is wearing the Cornerstone Mask, it is in its Cornerstone Mask form, and is dual-type Grass/Rock normally, becoming pure Rock-type in its Terastallized state. Teal Mask Ogerpon is the game mascot of The Teal Mask, appearing in The Hidden Treasure of Area Zero. It is associated with the Loyal Three and their leader, Pecharunt, and it is the last Pokémon in the Kitakami Pokédex.
