Stellar (type)
The Stellar type (Japanese: ステラタイプ Stellar type) is a type that exists only in Generation IX. Unlike other types, no Pokémon or moves bear it naturally, and it is exclusive to Terastallized Pokémon. Stellar-type moves are super effective against other Tera Pokémon.
In Pokémon Scarlet and Violet, it was revealed that the Stellar type and the Terastal phenomenon were created by Terapagos. Pokémon gain the Stellar Tera Type due to the influence of the crystals found in the Area Zero Underdepths.

Uniquely, the Stellar type has no defensive properties, as a Stellar-type Tera Pokémon will always retain its original typing's defensive properties. Outside of Terastallizing, any attempts to change a Pokémon's type into the Stellar type (such as the moves Conversion 2 or Reflect Type) will fail. Transforming into a Stellar type is a form of Terrastalization and as such, Stellar-type Pokémon are in practice always weak to Stellar-type moves, in addition to any weaknesses of their original typing.
If a Pokémon is hacked to have the Stellar type without Terastallizing, it is treated as a Poison type defensively.[1]
Additional effects
When a Pokémon Terastallizes into the Stellar type, it gains an attack boost for every move type, but only once per type; 2× for the Pokémon's original types and 1.2× (4915/4096) for every other type, including Stellar. After a move is used, no other moves of that same type will receive this boost from being Terastallized. In Tera Raid Battles, all moves will be boosted in this manner without limit. In its Stellar Form, Terapagos similarly retains this boost at all times.
Stellar-type Tera Blast gains increased base power at the cost of lowering the user's Attack and Special Attack stats by one stage, and Stellar-type Tera Starstorm changes to hit multiple opponents. Other moves cannot be changed into the Stellar type.
A Pokémon that Terastallizes into the Stellar type will be unable to use Transform. Imposter will also fail.
Pokémon
No Pokémon is naturally Stellar-type, but all Pokémon in Pokémon Scarlet and Violet (except Ogerpon) can become Stellar through Terastallization, while still being treated as its original type defensively.
Appearance
All Terastallized Stellar-type Pokémon (except Terapagos) are crystallized and coated in a rainbow aura. A Tera Jewel forms atop their head, taking the form of a white crown with its base covered in diamonds colored like all of the eighteen types. The crown is orbited by eighteen hexagonal gems each with the icon and color of its respective type. Atop the crown is a gem shaped like the Normal Form of Terapagos, but with an angry look. Floating above it is the symbol of the Terastal phenomenon, a hexagon with triangular extensions on each corner.
Unique Terastallized states
Terapagos cannot have any other Tera Type than Stellar.

Moves
No move is naturally Stellar-type, but two moves that are naturally Normal become Stellar and gain additional effects if the user has Terastallized into the Stellar type.
If a move is hacked to have the Stellar type without Terastallizing, it will have no effect and deal 0× damage.[2]

In the TCG
First introduced in the Stellar Crown expansion (the Japanese Stellar Miracle expansion), cards of Terastallized Pokémon ex with the Stellar type are known as Stellar Tera Pokémon ex. Stellar Tera Pokémon ex cards have types that follow the Pokémon's usual non-Terastallized typings, but have special powerful attacks that are named after gemstones and require three different types of Energy to use, including types that the Pokémon do not originally have in the core series. In addition to the usual Tera Pokémon ex design, Stellar Tera Pokémon ex cards have a white textbox with rainbow borders and multicolored crystal shards around the artwork.
The following is a list of all Stellar Tera Pokémon ex cards.
Trivia
- The Stellar type's icon is similar to Terastal Form Terapagos's shell seen from above. This is likely due to the shell displaying all of the other types's icons on it, similar to how the Stellar type can be considered a "mix" of all other types.
- The Stellar type is the only type:
- To be exclusive to a transformation mechanic.
- Without a type-boosting held item, damage-reducing Berry, gem, memory, or Plate.
- To be introduced mid-generation instead of at the beginning of a generation.
- Written in katakana, ステラタイプ (Sutera type) is an anagram of テラスタイプ (Terasu Type), the Japanese word for Tera Type.
- Stellar-type moves can only be resisted by the Tera Shell and Wonder Guard Abilities, the latter of which is unavailable in Pokémon Scarlet and Violet.
- Stellar-type moves have some similarity to Shadow moves.
- They are both exclusive to a single pair of games.
- They are both exclusive to a variation of a Pokémon created for those games (Terastal phenomenon and Shadow Pokémon).
- They both have special type interactions with that variation.
- Neither has any special interactions with other types.
- Pokémon who can use these moves have the same type interactions as their original forms, except for against the moves themselves.
