Ogerpon

Ogerpon is a Grass Type Legendary Pokemon introduced in Generation 9

Ogerpon has eight forms, four standard forms that depend on the mask it is wearing, which also changes its type, and another four that appear when Ogerpon Terastallizes, giving it a 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.

## Biology

Ogerpon is a predominantly green, humanoid Pokémon. Its green torso is spotted with white flowers and yellow dots, and it is capable of extending green and black vines of ivy. Its long legs are black in the front and white in the back, and its two-toed feet each have two green leaves sprouting between the toes. Its torso is mostly covered by a large, green, multicolored cloak-like structure that extends from a stem on top of its head. This cloak frames its face with a large, black, thorny vine, the two uppermost thorns resembling horns. While the cloak's sleeves move as if Ogerpon has arms beneath them, it actually has no arms or even shoulders; the cloak itself is prehensile and serves as its arms, with the "sleeves" able to grasp and manipulate objects. Ogerpon has an orange face, yellow eyes with white, star-shaped pupils and small green leaves at the edges that loosely resemble eyelashes, a three-pointed leaf that serves as hair, small black markings on its eyebrows and cheeks, and two pointed fangs in its upper jaw. Its face is usually hidden behind a mask, and in battle, it wields a large, spiky cudgel wrapped in ivy; these tools are stored under its cloak when not in use. Ogerpon is a female-only species.

It is a mischievous and curious Pokémon that enjoys spending time with humans while wearing a mask to blend in. It fights by confusing its opponents with its nimble movements and kicks, and it draws type-based energy from its masks, imbuing its cudgel with different elements. Ogerpon becomes weaker if its masks are taken away, and its full power can be restored to it by returning its masks. This species is known to have a very long lifespan; one specimen is confirmed to have been alive for hundreds of years.

Ogerpon is the only known Pokémon capable of using the move Ivy Cudgel. It is also the only known Pokémon that can have Embody Aspect as an Ability, albeit it is only acquired through the Terastal phenomenon.

### Forms

Ogerpon has eight different forms, with two corresponding to each of its four masks, and accordingly change the color of its cloak and the aura of its cudgel. Each standard form also has an associated special Terastallized state that causes the mask to transform, gain ogresque crystal horns, float in front of Ogerpon, and grow to such an immense size that it hides all but Ogerpon's legs when viewed from the front. Ogerpon's unique Terastallization comes from the intense emotions it feels. Because Ogerpon's Tera Type is wholly determined by the energy in its mask, it cannot be changed at the Treasure Eatery, unlike other Pokémon.

#### Teal Mask

The Teal Mask is primarily teal and green in color, and sports a mischievous expression that is sometimes described as fearsome. The grinning mouth is tan, with two extensions beneath it that resemble pincers. On each side of the mouth is a group of three green leaves, each one larger than the leaf beneath. The top of the mask features five teal leaves that form a crown of sorts, with the four outer leaves each having a hole cut towards the center. The mask contains nine Tera crystals: two that resemble squinting eyes, six as the "veins" of the green leaves, and one large, four-pointed crystal set in the central teal leaf as the crown jewel.

The Teal Mask draws upon the power of grass; while wearing it, Ogerpon's Tera Type is always Grass. It is said to have the power to restore life to withered plants.

#### Wellspring Mask

The Wellspring Mask is predominantly blue and white in color, and sports a crying expression. The entire mask is framed by blue hair that forms a heart shape, with a streak of lighter blue hair on each side. The face is white with circular, light blue eyebrows, simple black lines for a closed mouth and eyes, and two large tears made of Tera crystals beneath the eyes.

The Wellspring Mask draws upon the power of water; while wearing it, Ogerpon's Tera Type is always Water. With this mask, Ogerpon excels in both offense and defense, its unrelenting kicks and ivy strikes resembling the ceaseless gushes of spring water. It is said to be able to stop the flow of a river.

#### Hearthflame Mask

The Hearthflame Mask is mainly red and orange in color, and sports a fierce expression. Its whole shape and profile is flame-like, with a protruding brow of swirling flames and a bright orange mane bordering most of the mask. Its mouth and nose are bright blue, and it has two sharply pointed fangs jutting from its lower jaw. It has a Tera crystal on its forehead that is vaguely shaped like a four-pointed star, and its eyes are also Tera crystals, with simple black pupils and a small amount of black coloration between the eyes and nose.

The Hearthflame Mask draws upon the power of fire; while wearing it, Ogerpon's Tera Type is always Fire. True to the mask's expression, Ogerpon becomes more aggressive while wearing it, mercilessly spearing its enemies with thorny ivy and bombarding them with the intensity of a hearth's fire. It is said to be capable of rousing a candle's flame into a raging inferno.

#### Cornerstone Mask

The Cornerstone Mask is mostly gray in color, and sports a crazed expression. It has a craggy profile, with uneven extensions towards the top of the mask. Its mouth prominently juts out, and it has three flat Tera crystal teeth between two large, black, blunt-tipped fangs that curve upward. Its eyes are yellow with Tera crystals for pupils, it has a small, flat nose just over its mouth, and it has a bright-blue feature that begins behind its nose and curves upward beneath its eyes, forming a strange sort of moustache.

The Cornerstone Mask draws upon the power of stone; while wearing it, Ogerpon's Tera Type is always Rock. Ogerpon's defense brims with the solidarity of the cornerstones that support houses; its body becomes rock-solid and easily absorbs impacts, protecting it from all manner of attacks. It is said to be able to break even the hardest stone in two.

## Trivia

* Ogerpon is the only Pokémon whose Tera Type cannot be changed under normal circumstances in Pokemon Scarlet and Violet. Even if the game is modified to force Ogerpon to have a different Tera Type, the game will softlock upon trying to Terastallize, forcing the player to restart the console.
