Terastal phenomenon

The Terastal phenomenon (Japanese: テラスタル Terastal) is a temporary transformation affecting Pokémon that was introduced in Generation IX. This transformation gives the Pokémon a gem-like appearance and changes its type. Each individual Pokémon has a designated type it turns into when it Terastallizes, which is called its Tera Type (Japanese: テラスタイプ Teras-Type).


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]

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 started to solve the mystery. The professor discovered the energy emitted from shining crystals in Area Zero is what triggered the Terastal phenomenon. The Tera Orbs were then created by the professor from the Terastal energy located in Area Zero. Clavell helped support the research on it. 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 with Terastalizing.

The Scarlet Book/Violet Book 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 likely to be Terapagos, based on its description.


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, causes the Pokémon's body to glisten like gems. This changes the Pokémon's defensive type(s) to its Tera Type, removing all other types. 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 the type(s) they had immediately before Terastallizing. If the Pokémon's Tera Type is the same as one of its original types, moves of that type receive an ×2 power boost instead of the usual ×1.5.[1]

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 base power below 60 but are not a multi-strike move or an increased priority move are stealthily boosted to 60BP; this is checked for after Technician's boost.[2] Pokémon can only have one Tera Type. The move Tera Blast changes type to the Pokémon's innate Tera Type upon Terastallization.[3]

Terastallized Pokémon cannot have their type changed from moves and Abilities such as Soak, Double Shock, Protean, or Transform. A Pokémon using Transform before Terastallizing will not copy its opponent's Tera Type and will instead keep its own. Additionally, if a Pokémon Terastallizes and then uses Transform, they will appear to lose their Tera Jewel but retain the crystalline body texture.

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 visiting a Pokémon Center.[1] An exception to this can be found in Area Zero, where the Tera Orb will automatically recharge each time it is used.

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.

The Terastal phenomenon is only found in Paldea, apparently due to the Terastal energy seeping from the ground of the region.[1]

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

There are precisely 68 wild Tera Pokémon scattered around Paldea, 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, and when battled against will immediately Terastallize. Wild Tera Pokémon cannot be caught while Terastallized until after they lose their Terastallization, which will happen after sustaining a certain amount of damage from direct attacks. Once this threshold is reached, the damage the Pokémon has taken will be capped until they lose their Terastallization, even from multi-strike moves.

Wild Tera Pokémon will eventually respawn after being caught or defeated and will always have a perfect 31 in at least three of their IVs.

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.
