Terastal phenomenon

Artwork of the Terastal phenomenon

The Terastal phenomenon or Terastallization (Japanese: テラスタル Terastal) is a temporary transformation affecting Pokémon that was introduced in Generation IX. It gives Pokémon a gem-like appearance and changes its type.

Etymology

The name "Terastal" likely derives from the Japanese word 照らす terasu (to illuminate; to shine) and the English word crystal.

Terminology

Some terms related to this game mechanic include:

• Terastal phenomenon or Terastallization (Japanese: テラスタル Terastal) is the transformation.
• Terastallize (Japanese: テラスタルする Terastallize) is the related verb for this transformation.
• Tera Pokémon (Japanese: テラスタルポケモン Terastal Pokémon), also known as Terastallized Pokémon (Japanese: テラスタルしたポケモン Terastallized Pokémon), are Pokémon affected by this transformation.
• Terastallized state (Japanese: テラスタルした姿 Terastal Appearance) refers to the crystallized appearance of a Pokémon after Terastallizing. Two Pokémon (Ogerpon and Terapagos) have unique Terastal states that further change the Pokémon's appearance.
• Terastal energy (Japanese: テラスタルエネルギー Terastal energy) is the energy involved in this transformation.
• The Tera Type (Japanese: テラスタイプ Teras Type) is the type of the Terastallized Pokémon.

• There are two moves related to this phenomenon:
  • Tera Blast (Japanese: テラバースト Tera Burst) is a move that deals damage based on the user's Tera Type if the user has Terastallized.
  • Tera Starstorm (Japanese: テラクラスター Tera Cluster) is Terapagos's signature move. It deals super effective damage on Terastallized targets.
• There are three Abilities related to this phenomenon, all exclusive to a form of Terapagos:
  • Tera Shift (Japanese: テラスチェンジ Tera Change) is exclusive to its Normal Form. It causes Terapagos to change into its Terastal Form when it enters battle.
  • Tera Shell (Japanese: テラスシェル Tera Shell) is exclusive to its Terastal Form. It causes all damage-dealing moves to become not very effective on Terapagos while its HP is full.
  • Teraform Zero (Japanese: ゼロフォーミング Zero-Forming) is exclusive to its Stellar Form. It negates all effects of weather and terrain.
• Terastal Form (Japanese: テラスタルフォーム Terastal Form) is a form taken in battle by Terapagos through its Tera Shift Ability.

Some examples of in-game dialogue from Pokémon Scarlet and Violet:

• "When it is charged with energy, it can be used to cause Pokémon to Terastallize." (excerpt from the description of Tera Orb)
• "If the user has Terastallized, it unleashes energy of its Tera Type." (excerpt from the description of Tera Blast)

History

Spoiler warning: this article may contain major plot or ending details.

There is a lot of mystery surrounding the Terastal phenomenon and why it only happens in Paldea. Professor Sada^S/Professor Turo^V was known to be researching this mysterious transformation. It is later revealed that the Terastal phenomenon also occurs in Kitakami and has even been replicated by technological means in the grounds of Blueberry Academy in Unova, through the use of materials from Paldea and Kitakami.

The Terastal phenomenon was first discovered 140 years ago in Area Zero along with Terastallized Pokémon at the bottom of the Great Crater of Paldea. However, attempts to remove Terastallized Pokémon from the crater caused the light to disappear. Further details of the Terastal phenomenon thus remained unclear for a while.

Ten years before the events of Pokémon Scarlet and Violet, the game's professor began investigating the phenomenon, and discovered that the energy emitted from shining crystals in Area Zero is what triggers it. The Tera Orbs were then created by the professor from the Terastal energy located in Area Zero, with support from Director Clavell. This allowed people to Terastallize their Pokémon outside of Area Zero. The Tera Orb was then shared to the Paldea League and Naranja Academy^S/Uva Academy^V.

At some point, the Terastal energy was used by the professor to create a time machine, bringing in Paradox Pokémon from the ancient past^S/distant future^V, including a pair of Koraidon^S/Miraidon^V.

The crystalline petals of Glimmora seem to resemble the Tera Jewels that appear during the Terastal phenomenon. It is unknown if there is a connection between Glimmora and the Terastal phenomenon, though many of them (along with its pre-evolution, Glimmet) can be found in Area Zero, the place where the phenomenon originated. Additionally, eight Glimmet Crystals are needed to make TM171 (Tera Blast), a move that changes type upon Terastallizing.

The Scarlet Book^S/Violet Book^V makes cryptic hints that it may be linked to an unknown Pokémon resembling a disk made of layers of overlapping hexagons, but the truth of this has yet to be confirmed. A journal in Research Station No. 1 further implies its existence and relationship to the phenomenon. The journal reads:

"We've determined that this energy crystallization is linked to the being we call ▊▊▊▊▊▊. The interlocking hexagonal plates that comprise ▊▊▊▊▊▊'s shell must somehow cause this phenomenon—which I've dubbed 'Terastallizing.'"

This Pokémon is ultimately confirmed to be Terapagos. A nineteenth Tera Type, the Stellar type, was later discovered and named by Professor Sada^S/Professor Turo^V.

Effects

Concept art of Fire-type and Water-type Tera Jewels from Pokémon Scarlet and Violet

Trainers who obtain a Tera Orb are able to use it to Terastallize their Pokémon, which makes a Tera Jewel appear above the Pokémon's head and causes the Pokémon's body to glisten like polished, faceted gemstones. This changes the Pokémon's defensive type(s) to its Tera Type, removing all other types, but gives a weakness to Stellar-type attacks, which can only be used by Stellar-type Tera Pokémon. Terastallized Pokémon are identified by having "Tera" in front of their name.

While Terastallized, Pokémon receive STAB on moves matching their Tera Type, in addition to moves matching their original types. The original types are the types they had immediately before Terastallizing (taking type changes into account) or their base types if they were sent on the field while Terastallized. If the Pokémon's Tera Type is the same as one of its original types, moves of that type receive a ×2 power boost instead of the usual ×1.5.

Terastallization takes priority over all moves.

During this time, Adaptability works only for the Tera Type (with ×1.5 becoming ×2, and ×2 becoming ×2.25). Additionally, moves of the Tera Type that have a base power below 60 are increased to 60 base power; this is checked for after Technician's boost . The boost does not apply to multistrike moves or moves with increased priority. Moves that increase in power (such as Rollout) are boosted if its base power would be below 60 when used, but moves with variable power based on other factors (such as Water Spout) are not boosted, regardless of what its base power would be when used. Pokémon can only have one Tera Type. The move Tera Blast changes type to the Pokémon's innate Tera Type upon Terastallizing.

Terastallized Pokémon cannot have their type changed from moves and Abilities such as Soak, Double Shock, Imposter, Protean, or Transform. A Pokémon using Transform before Terastallizing will not copy its opponent's Tera Type and will instead keep its own.

Similar to Mega Evolution, the Terastal phenomenon lasts until the battle ends or the Terastallized Pokémon faints. After being used once, the Tera Orb loses all its Terastal energy and has to be recharged by either touching crystals containing Terastal energy or by visiting a Pokémon Center. An exception to this can be found in Area Zero, where the Tera Orb will automatically recharge at the end of each battle after it is used. Upon capturing Terapagos at the end of The Indigo Disk, the Tera Orb will be infused with Terapagos' energy and will no longer require charging.

After beating the Medali Gym, the player can change their Pokémon's Tera Type at the Treasure Eatery by exchanging 50 Tera Shards of a given type with the chef. However, the Tera Type of Ogerpon and Terapagos cannot be changed.

The Terastal phenomenon is currently only known to be found in certain areas of the Pokémon world: Paldea, due to the Terastal energy seeping from the ground of the region, which was supposedly created by the Terapagos slumbering within the Great Crater of Paldea; Kitakami, due to the Terastal energy found in the Crystal Pool, which creation is unknown; and Blueberry Academy in Unova, due to the Core hanging from the roof of the Terarium, which created by Briar using soil from Paldea and the water from Kitakami's Crystal Pool.

Catching Tera Pokémon

Normal wild Pokémon found in Paldea typically have a Tera Type that matches one of their normal types. This Tera Type does not reflect their potential evolutions and cannot be passed down through breeding. For example, a Charcadet will always have a Fire Tera Type. Typically, there are only two ways to obtain a wild Tera Pokémon with unique typing: either catch a wild Tera Pokémon scattered around Paldea, or participate in a Tera Raid Battle. These Pokémon may know TM moves that match this set Tera Type.

Wild Tera Pokémon

Main article: List of wild Tera Pokémon

There are 68 wild Tera Pokémon scattered around Paldea, the majority with unique Tera Types. In Kitakami, there are 22 wild Tera Pokémon scattered around the land. In the Terarium, there are 21 wild Tera Pokémon scattered around the facility, the majority with unique Tera Types. They can be found in fixed locations and typically have Tera Types different from their base types, a notable exception being the eight Eeveelutions, who have Tera Types that match their base types, and would normally have a Normal Tera Type if evolved from Eevee. The wild Tera Pokémon are indicated by a bright glow emitting from their bodies, which is different if the Tera Type is Stellar. Wild Tera Pokémon will always have a perfect 31 in at least three of their IVs and their scale value is always at least 200.

When battled against, they will immediately Terastallize. Wild Tera Pokémon cannot be caught while Terastallized. If an attack deals enough damage to drop them to 20% of maximum HP, all further damage from that attack (including from multistrike moves) will be prevented, their Tera Jewel will break, and if the Tera Pokémon has not already moved that turn, it will skip its turn. However, if indirect damage such as poison or burn reduces the Pokémon's HP below 20%, that damage will not be prevented, and a direct attack at that point has another chance to cause the Tera Jewel to break at 1 HP. Indirect damage can reduce the Pokémon to 0 HP while it still has its Tera Jewel, in which case it will faint without ever becoming catchable. When caught or defeated, the player is rewarded with League Points, and with 10 Stellar Tera Shards if their Tera Type is Stellar (other Tera Types do not reward any Tera Shards).

Wild Tera Pokémon will eventually respawn at the same location after being caught or defeated: each real-time day, they have a chance to respawn. Contrary to other wild Tera Pokémon, Stellar ones do not always respawn as the same species: instead, the species is chosen at random in a pool specific for each one. Whether or not a Tera Pokémon respawns, and which species appears at Tera Stellar spawn spots, can be manipulated by soft resetting as long as the player did not get too close to the spawn spot when saving.

Tera Raid Battle

Tera Raid Battles occur all over Paldea, with the locations changing at random each real-life day at midnight. These locations are indicated on the map, and in the overworld are indicated by a large, colored "shining crystal", with a beam of sparkling lights shooting into the sky.

In addition, more Tera Raid crystals spawn if the player clears out many of them and is running out of Tera Raid Battles to do. Therefore, the player can never be unable to participate in Tera Raid Battles.

Tera Jewels

Tera Jewels are large crystal crowns that form atop a Terastallized Pokémon's head. Each Tera Type possesses a different Tera Jewel to represent it, which contains two basic structures: the crown band that acts as the Tera Jewel's base, and the gem that stands above the band. Except for the Stellar type, each Tera Jewel's base has a hexagonal crystal on the front, with a pair of angry-looking eyes on it.

Type	Image	Description
Normal		The Normal-type Tera Jewel has an off-white band. On its front, there is a yellow hexagonal crystal with a pair of angry-looking eyes on it. Atop it, there is a large, white diamond held by golden prongs. The band is surrounded by three smaller white diamonds also held up by golden prongs, separated from each other radially by 120 degrees.
Fighting		The Fighting-type Tera Jewel has a reddish-orange band similar in appearance to a championship belt. A red hexagonal crystal with angry-looking eyes on it is embedded on the front. Atop the band, there is a large, red fist shaped in an uppercut motion, surrounded by a spiraling teal shockwave.
Flying		The Flying-type Tera Jewel has a bluish-white band shaped like a cluster of clouds. On its front, there is a cyan hexagonal crystal with a pair of angry-looking eyes on it. Atop it, there is a cluster of balloons — two red and two green — held by chains of gems.

Ground		The Ground-type Tera Jewel overall resembles a cut-through model of an Earth-like planet, with different layers representing the crust, mantle, outer core, and inner core. The Tera Jewel's base is the inner core, which is cream in color with an orange hexagonal crystal on the front. The crystal has a pair of angry-looking eyes on it.
Rock		The Rock-type Tera Jewel has a white band similar to a pedestal. Atop it, there is a large, stony temple closely resembling those of Greek and Roman temples. A brown hexagonal crystal with a pair of angry-looking eyes on it sits on the front of the pedestal, just below the temple base, which is surrounded by clusters of rocks on its four corners.
Bug		The Bug-type Tera Jewel has a greenish band with a flower-shaped crown. On its front, there is a dark green, hexagonal crystal with a pair of angry-looking eyes on it. Atop the crown is a small crystal adorned with two pairs of large, white insect wings and a pair of long, curled, green antannae.
Ghost		The Ghost-type Tera Jewel has a gray band composed of several gravestone-like structures, with a gap on the front. A dark gray hexagonal crystal with a pair of angry-looking eyes on it is situated within the gap. Atop it, there's a large, grinning, purple ghost.
Steel		The Steel-type Tera Jewel comprises a large, single-bladed axe situated atop a plain, cylindrical, gray band split in half. On the front gap between each halves of the band, there is a black hexagonal crystal with a pair of angry-looking eyes on it.
Fire		The Fire-type Tera Jewel has an orange band shaped like flames. On its front, there is a red hexagonal crystal with a pair of angry-looking eyes on it. Atop it, there is a large, red candelabra, holding five white, lit candles.

Grass		The Grass-type Tera Jewel has a greenish crown shaped like bushes or grass. On its front, there is a green hexagonal crystal with a pair of angry-looking eyes on it. Atop it, there is a large bouquet composed of blue, red, white, and yellow flowers.
Electric		The Electric-type Tera Jewel overall is shaped like a lightbulb, with a transparent white bulb enclosing a yellow filament shaped like a thunderbolt, and a yellow base. On the front of the base, there is a yellow hexagonal crystal with a pair of angry-looking eyes on it.
Psychic		The Psychic-type Tera Jewel has a pinkish band comprising two circles stacked atop each other. On its front, there is a purple hexagonal crystal with a pair of angry-looking eyes on it. Atop it, there is a large, violet, eye-like structure, with a large spherical gem at the center, serving as its pupil.
Ice		The Ice-type Tera Jewel has a cyan band shaped like a circle of ice cubes. On its front, there is a dark blue hexagonal crystal with a pair of angry-looking eyes on it. Atop it, there is a large, cyan snowflake.
Dragon		The Dragon-type Tera Jewel is has a reddish crown shaped like a castle's tower or a fortress. On its front, there is a cyan hexagonal crystal with a pair of angry-looking eyes on it. Atop it, there is a large, black dragon spreading out its red wings.
Dark		The Dark-type Tera Jewel has a grayish-white circular crown covered in spikes. On its front, there is a black hexagonal crystal with a pair of angry-looking eyes on it. Atop it, there is a mosaic of a spiky face with a mischievous grin, comprising various panels of red, yellow, and purple crystals embedded within a black frame.
Fairy		The Fairy-type Tera Jewel has a pinkish band shaped like a ribbon, with a knot on the front. On the front of this knot, there is a pink hexagonal crystal with a pair of angry-looking eyes on it. Atop it, there is a large, magenta heart spreading out a pair of white wings, each adorned with teardrop-shaped crystals for feathers.
Stellar		The Stellar-type Tera Jewel has a white crown with a base surrounded by diamonds colored after all of the eighteen other types. It is orbited by eighteen hexagonal gems, each having the icon and color of one of the eighteen other types. Atop it, there is a crystal in the shape of Terapagos in its Normal Form, with a pair of angry-looking eyes on its face. Floating above it, there is the symbol of the Terastal phenomenon — a dark blue hexagon with triangular extensions on each corner.

Unique Terastallized states

Some Pokémon species have unique Terastallized states, which change their appearance significantly upon Terastallizing, beyond the standard crystallized appearance of Terastallization. Additionally, the Pokémon's Ability changes after the Terastallization. There is no official name for this class of Terastallized state. Unlike other Pokémon, the few ones with a unique Terastallized state are the only ones which cannot have their Tera Types changed in Treasure Eatery.

Ogerpon and Terapagos are the only Pokémon known to have their own distinct Terastallized states. Ogerpon's Tera Type changes depending on the mask that it is currently holding. Even though Ogerpon's Terastallized states are not recognized as separate forms in the Pokédex, Terapagos's Terastallized state not only is, but is also uniquely recognized as its Stellar Form.

Main article: Pokémon ex (TCG) → Tera Pokémon ex

Terastallized Pokémon were first introduced in the English Scarlet & Violet expansion (the Japanese Scarlet ex and Violet ex expansions) as Pokémon ex cards. These Pokémon are known as Tera (Japanese: テラスタル Terastal) Pokémon ex. While on the Bench, Tera Pokémon ex do not receive any damage from attacks done by either player.

Some Tera Pokémon ex can have types that differ from their usual ones. These so-called "type-shifted" Tera Pokémon ex use the same Energy as their usual type for attacks, while their Weakness and Resistance will correspond with the shifted type. For instance, Charizard ex from Obsidian Flames is a Darkness-type Pokémon, but its Burning Darkness attack requires Fire-type Energy.

The English Stellar Crown expansion and the Japanese Stellar Miracle expansion introduce Terastallized Pokémon with the Stellar type. Cards of Terastallized Pokémon with the Stellar type have a unique distinction: each of these cards has a TCG type that follows their usual typing, as well as a uniquely powerful attack that requires three different Energy types to power it up. The Tera effect otherwise applies just the same as other Tera Pokémon ex cards.

Some cards have effects that reference or check for Tera Pokémon.

Trivia

• Similar to Dynamax, NPC Trainers don't freely Terastallize their Pokémon like a real player would, instead certain Trainers are programmed to Terastallize a particular Pokémon immediately.
• NPC partners in Tera Raid Battles don't Terastallize their Pokémon.
• Prior to the introduction of Crispin in The Indigo Disk, if the player chooses Fuecoco, no NPC Trainer in Pokémon Scarlet and Violet Terastallizes their Pokémon into the Fire type.
• Katy is the only NPC Trainer to use a Terastallized Pokémon that is not fully evolved in her final team, as Ursaring is unable to evolve into Ursaluna in Scarlet and Violet.
• The Terastal phenomenon is one of the few transformation gimmicks that can be found in more than one region, along with Mega Evolution.
• The Tera Jewels for all Terastallized states (except Ogerpon's) possess a small hexagonal crystal on the front of the crown, with a pair of angry-looking eyes on it.
  • For the Tera Jewels of the Stellar Tera Type's Terastallized state and Terapagos's Stellar Form, instead of the hexagonal crystal, there is a gem shaped like the Normal Form of Terapagos on top of the crown, with the same pair of angry-looking eyes as in other Tera Jewels.
