  • 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:

    • 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)
  • "If an opponent’s Pokémon Terastallizes during battle... observe a Pokémon's Tera Jewel closely to see which type it has become!" (Hassel)
  • "Terastallizing gives a real boost, see!" (Nemona)

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 SadaS/Professor TuroV was known to be researching this mysterious transformation.[1] 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 AcademyS/Uva AcademyV.

At some point, the Terastal energy was used by the professor to create a time machine, bringing in Paradox Pokémon from the ancient pastS/distant futureV, including a pair of KoraidonS/MiraidonV.

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 BookS/Violet BookV 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 SadaS/Professor TuroV.[2]

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.[1]

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 [3]. The boost does not apply to multi-strike 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.[4]

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.[1] 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, apparently due to the Terastal energy seeping from the ground of the region[1], Kitakami, due to the energy found in the Crystal Pool, and Blueberry Academy's Terarium in Unova, due to the Terarium Core hanging from the roof of the facility.

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.

When battled against, they will immediately Terastallize. Wild Tera Pokémon cannot be caught while Terastallized until after they lose their Tera Jewel, which will happen after sustaining a certain amount of damage from direct attacks. When they lose their Tera Jewel, they are unable to move for the remainder of the turn. Once this threshold is reached, the damage the Pokémon has taken will be capped until they lose their Tera Jewel, even from multi-strike moves. They will always have a perfect 31 in at least three of their IVs and their scale value is in a higher range than normal. When caught of 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 specie is chosen at random in a pool specific for each one.

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 forms atop a Terastallized Pokémon's head. Each Tera Type possesses a different Tera Jewel to represent it.

Unique Terastallized states

Some Pokémon species have unique Terastallized states, which change their appearance significantly upon Terastallizing, beyond the standard crystallized appearance of Terastallization. Additionaly, 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.

The Terastal phenomenon debuted in Nemona and Brassius and…, where Brassius Terastallized his Sudowoodo into a Grass type during his battle with Roy. After the battle, Nemona explained how the phenomenon works to Liko and Roy.

In Fly! Wattrel!!, Friede Terastallized his Charizard into a Dark type during his fight against Spinel's Magneton and Beheeyem. In Rivals in the Dark of Night!, he Terastallized his Charizard into a Dark type again in his battle against Amethio's Ceruledge at Diana's ancient castle. This showed that Terastallization is possible in regions not related to Paldea, as they were in the Galar region at the time.

In HZ034, Hamber Terastallized his Dusknoir into a Ghost type during his training battle with Amethio, coming out victorious. In the same episode, Nidothing published a video about the Terastal phenomenon, having her Quaxly dress up as if it Terastallized into a Water and a Normal type.

In HZ045, Amethio used his newly obtained Tera Orb to Terastallize his Ceruledge into a Ghost type to battle the Black Rayquaza. Right after him, Friede Terastallized his Charizard into a Dark type as well and joined forces with Amethio in the battle against Rayquaza. However, both were still defeated by Rayquaza's overwhelming power.

In HZ046, images of a Terastallized Jigglypuff, Fletchling, and Eevee appeared in a video shown by Geeta about the Terastal training.

In HZ047, Liko Terastallized her Floragato into a Grass type for the first time during her battle against Katy, who countered this by Terastallizing her Teddiursa into a Bug type, which ended with Liko's defeat.

In HZ048, Roy Terastallized his Fuecoco into a Fire type for the first time during his rematch with Brassius, which ended with Roy's victory.

In HZ050, Dot Terastallized her Quaxly into a Water type for the first time during her battle against Iono, who countered this by Terastallizing her Bellibolt into an Electric type, which ended with Dot's defeat.


Pokémon: Paldean Winds

In Breathe In, during a rematch between Aliquis and Nemona, both Trainers Terastallized their Pokémon, his Meowscarada into a Grass type and her Combat Breed Paldean Tauros into a Fighting type, respectively, the battle ended with another one of Nemona's victory.

In Breathe Together, a Trainer's Terastallized Electric type Pawmot was seen battling against Aliquis's Terastallized Grass type Meowscarada.



In the animated video for the song Biri-Biri, a Terastallized Rock type Glimmora briefly appeared. Afterwards, Anna Terastallized her Skeledirge into a Fire type while Nemona Terastallized her Meowscarada into a Grass type during their battle.


In the manga

Pokémon Adventures

Scarlet & Violet arc

Terastallization debuted in PASV01, when Nemona Terastallized her Pawmi into an Electric type to battle an unnamed student, who in response, Terastallized their Pikachu into a Flying type, however, the exhibtions battle was interrupted before someone came out victorious.

In PASV05, Violet used his newly obtained Tera Orb to Terastallize his Nymble into a Bug type so it succeedes in defeating Giacomo's Segin Starmobile.

In PASV06, Katy Terastallized her Teddiursa into a Bug type during her Gym battle with Scarlet. It defeated her Sprigatito, but lost to her Pikachu who was Terastallized into a Flying type again.


In the TCG

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 Japanese Stellar Miracle expansion introduces 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.

  • 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 unevolved 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.
