The introduction of the Stellar type in the Generation IX Indigo Disk DLC marked the first time since the Fairy type that a 19th elemental category entered the Pokemon franchise. However, unlike the 18 traditional types, the Stellar type functions under a completely different set of rules. It is a specialized mechanic tied exclusively to Terastallization, functioning less as a defensive pivot and more as a universal offensive catalyst. Understanding the nuances of Stellar type Pokemon is essential for anyone navigating the current competitive landscape of Pokemon Scarlet and Violet.

The Mechanics of the 19th Type

Stellar type Pokemon do not exist in the wild as a base typing. No Pokemon naturally carries the Stellar type, and no existing moves are naturally Stellar-type. The only exception to this rule is Terapagos, the legendary Pokemon of Area Zero, specifically in its Stellar Form. For every other Pokemon, the Stellar type is attained solely through the Terastal phenomenon.

When a Pokemon terastallizes into the Stellar type, its appearance changes significantly. It gains a rainbow-colored crystalline aura, and its Tera Jewel becomes a white crown adorned with eighteen different gems, representing the full spectrum of Pokemon types. This visual cue is a direct reflection of its mechanical purpose: the unification of all types into a single offensive force.

The Multiplier Logic

One of the most complex aspects of Stellar type Pokemon is how they handle damage multipliers. Standard Terastallization typically changes a Pokemon's type to a single element, granting a 1.5x Same Type Attack Bonus (STAB) to moves of that type, or increasing the STAB to 2.0x if the Pokemon was already that type. The Stellar type deviates from this pattern significantly:

  1. Original STAB Moves: If a Pokemon uses a move that matches one of its original, non-Terastallized types, the damage is boosted by 2.0x.
  2. Other Type Moves: For moves of any other type (including the Stellar type itself), the damage receives a 1.2x boost (precisely 4915/4096 in game code).
  3. The "Once-per-Type" Restriction: In standard competitive battles (VGC or Singles), these boosts only apply the first time a move of a specific type is used. For example, if a Stellar-type Meowscarada uses Flower Trick, that move gets the 2.0x boost. If it uses Flower Trick again on the next turn, it receives no Tera-related boost. However, it could then use Knock Off to get a one-time 2.0x boost for its Dark typing, or U-turn for a 1.2x boost for its Bug typing.

This restriction creates a unique "all-out attacker" dynamic. In Tera Raid Battles, however, this restriction is lifted, allowing Stellar type Pokemon to benefit from the boost on every single turn, which is why the Stellar type is frequently seen in high-level raiding strategies.

Offensive Dominance vs. Defensive Vulnerability

Perhaps the most critical distinction between the Stellar type and traditional Tera types is the defensive property. Usually, Terastallizing is used to shed a Pokemon's weaknesses. A Garchomp might turn into a Steel-type to resist Ice-type moves. A Stellar-type Pokemon, however, retains the defensive weaknesses and resistances of its original typing.

If a Dragon/Flying-type Dragonite terastallizes into the Stellar type, it remains weak to Ice, Rock, and Fairy moves. It does not gain any resistances inherent to the Stellar type because the Stellar type has no defensive properties. This makes the Stellar type a high-risk, high-reward choice. You are essentially trading the defensive utility of Terastallization for a broader, albeit limited, offensive coverage.

The Stellar Tera Blast

The move Tera Blast undergoes a unique transformation when used by a Stellar type Pokemon. Normally, Tera Blast changes its type to match the user's Tera type. When the user is Stellar-type, Tera Blast becomes a Stellar-type move with a base power of 100 (up from the usual 80).

Its properties are as follows:

  • Super Effective against Tera Pokemon: Stellar-type Tera Blast deals super-effective damage to any opponent that has terastallized, regardless of what their Tera type is. This makes it an incredible tool for punishing an opponent who has already committed their Terastal charge.
  • Neutral Damage Elsewhere: Against non-terastallized targets, it deals neutral damage across the board.
  • The Stat Penalty: Using Stellar-type Tera Blast lowers the user's Attack and Special Attack stats by one stage. This reinforces the "one-time use" philosophy of the type, as successive uses become increasingly weaker unless the Pokemon has specific abilities to mitigate the drop.

The Terapagos Factor

Terapagos is the cornerstone of the Stellar type lore and mechanics. While other Pokemon use the Stellar type as an additive boost, Terapagos is built around it. In its Stellar Form, which is triggered upon Terastallizing in battle, Terapagos becomes the ultimate manifestation of this power.

Unlike other Pokemon, Terapagos in its Stellar Form does not suffer from the "once-per-type" boost limitation. It enjoys the damage increases indefinitely throughout the battle. Furthermore, its signature move, Tera Starstorm, becomes a Stellar-type move with 120 base power. In a double battle, Stellar-type Tera Starstorm hits both opponents, making it one of the most oppressive spread moves in the current meta. It bypasses the usual damage reduction for spread moves while maintaining its massive power output.

Competitive Strategy and Viable Candidates

Integrating Stellar type Pokemon into a competitive team requires a departure from traditional Tera-focused thinking. Since it offers no defensive protection, the chosen Pokemon must either be fast enough to secure a KO before being hit or bulky enough to survive despite its original weaknesses.

The Contrary Strategy

One of the most effective users of the Stellar type is Serperior. This is due to the ability Contrary, which reverses stat changes. Normally, Stellar-type Tera Blast lowers the user's offensive stats. For Serperior, it increases Attack and Special Attack by one stage. This allows Serperior to spam a 100-power move that hits Terastallized opponents for super-effective damage while simultaneously setting up its own sweep.

Protean and Libero Users

Pokemon with Protean (like Meowscarada) or Libero (like Cinderace) also find a unique niche with the Stellar type. Since the Stellar type maintains the original typing for defensive calculations but allows for the offensive flexibility of these abilities, players can cycle through their movesets to maximize the one-time boosts provided by the Stellar Tera crown.

Mixed Attackers

Because the Stellar type boosts the damage of every move type once, Pokemon with diverse coverage moves benefit significantly. A Pokemon like Iron Valiant, which can run a wide variety of Fairy, Fighting, Psychic, and Electric moves, can utilize the Stellar type to secure KOs that would otherwise be just out of reach due to the 1.2x multiplier on its coverage options.

Unlocking and Farming Stellar Shards

To change a Pokemon's Tera type to Stellar, a trainer must collect 50 Stellar Tera Shards. These are distinct from the standard elemental shards and are primarily found in the Area Zero Underdepths.

After completing the main story of the Indigo Disk DLC, players can encounter wild Stellar Tera Pokemon within the Terarium of Blueberry Academy. Defeating these specialized wild encounters typically yields 10 Stellar Shards per battle. Additionally, players can fly to the top of the Terarium Core to find a one-time stash of 50 shards, allowing for an immediate transformation of a favorite Pokemon.

Changing the type is done at the Treasure Eatery in Medali. The chef there will cook a special Stellar-type meal in exchange for the shards, provided the player has already defeated the Medali Gym Leader.

Stellar Type in the Pokemon TCG

The influence of the Stellar type extends beyond the video games into the Pokemon Trading Card Game, notably starting with the Stellar Crown expansion. In the TCG, Stellar Tera Pokemon ex cards are easily identifiable by their white text boxes and rainbow borders.

These cards follow a different logic than the video game but maintain the theme of "multi-type energy." Stellar Tera Pokemon ex often have incredibly powerful attacks that require three different types of energy to activate. For instance, a Stellar Tera Terapagos ex might require Water, Grass, and Lightning energy for its primary attack. This forces TCG players to build complex, multi-energy decks, mirroring the "all-types-in-one" philosophy seen in the digital battles.

Conclusion on the Meta Impact

The Stellar type is not a replacement for traditional Terastallization but rather a specialized alternative. While many players prefer the defensive safety of turning a Gholdengo into a Water-type or a Dragonite into a Normal-type, the Stellar type offers a surgical offensive tool. It is the ultimate anti-meta option, designed specifically to punish the very mechanic it belongs to. By providing a super-effective answer to any Terastallized opponent, the Stellar type ensures that no Pokemon is truly safe once they activate their Tera Jewel. As strategies evolve, the 19th type remains a testament to the depth of Generation IX's battle mechanics, offering a rainbow of possibilities for those willing to embrace its unique complexity.
