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 along with changing into the exclusive Tera Type (Japanese: テラスタイプ Teras-Type).

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.

The Terastal phenomenon was first discovered 140 years ago in Area Zero along with Terastallized Pokémon. 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.

10 years before the events of Pokémon Scarlet and Violet, Professor Sada^S/Professor Turo^V 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 Professor Sada^S/Professor Turo^V 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 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.

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 book in research station 1 further implies its existence and relationship to the phenomenon. The book 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"."

Effects

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, and changes the Pokémon's type(s) to its Tera Type, removing all other types. Terastallized Pokémon are identified by having "Tera" in front of their name. The phenomenon is only found in Paldea, apparently due to the Terastal energy seeping from the ground of the region.

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. During this time, Adaptability only works 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. Pokémon can only have one Tera Type. The move Tera Blast changes type to the Pokémon's innate Tera Type upon Terastallization. Terastallized Pokémon cannot have their type changed from moves and Abilities such as Soak, Double Shock, and Protean.

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. Wild Terastallized Pokémon can be found both in the overworld in Paldea and in Tera Raid Battles. These Pokémon may know TM moves that match this set Tera Type. Wild Pokémon cannot be caught while Terastallized, and they will lose their Terastallization after sustaining a certain amount of damage from attacks. 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 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.

A Pokémon using Transform will not copy its opponent's Tera Type and 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.
