Ogerpon is a Legendary Pokémon first discovered in Kitakami. It was introduced in The Teal Mask DLC for Pokémon Scarlet and Violet. It has four forms: Teal Mask, Wellspring Mask, Hearthflame Mask, and Cornerstone Mask—each form possessing a unique Terastallized state. According to legend in The Teal Mask, it is said to have terrorized the land of Kitakami before being stopped by the Loyal Three: Okidogi, Munkidori and Fezandipiti. However, in reality, it defeated the trio for stealing three of its masks and hurting its human companion, but the villagers watching it assumed it had come to attack the village, seeing it as a terrible ogre. Only the mask maker who made Ogerpon's masks knew the true story, with this story being passed down to his descendants.
