What is the Terastal phenomenon?
This phenomenon is found only in the Paldea region and makes Pokémon shine and glimmer like gems.
When a Pokémon Terastallizes, a Tera Jewel appears above the Pokémon’s head like a crown, and the Pokémon’s body glistens like a cut gemstone.
It’s said that the Terastal energy that seeps from the ground of the Paldea region is involved in the phenomenon.
Many details remain unclear, but Professor Sada and Professor Turo are researching this mystery.
The Tera Jewel and the luster on the Pokémon’s body differ depending on the type.
Terastallizing holds the key to victory or defeat in battles in the Paldea region.
All Pokémon in Paldea can Terastallize to gain special power. First, each Pokémon has a Tera Type. A Pokémon's Tera Type is inactive until the Pokémon Terastallizes, at which time the Pokémon's type will change to its Tera Type. For example, some Eevee will have a Normal Tera Type, but some other Eevee have a Flying Tera Type.
There are 18 types, meaning there are countless combinations of Pokémon and Tera Types.
Terastallizing a Pokémon allows you to enhance your battle strategies by increasing the power of any moves that have the same type as your Pokémon’s Tera Type or by changing your Pokémon’s weaknesses. When to activate this special transformation and the combination of Pokémon and Tera Types you choose to use are all up to you.
Only select Trainers in the Paldea region are allowed to carry this special item.
Once you Terastallize a Pokémon, your Tera Orb will lose all its Terastal energy, and you won’t be able to use it again until it’s been recharged. You can charge your Tera Orb if you touch crystals overflowing with Terastal energy or go to a Pokémon Center. Only select Trainers in the Paldea region are allowed to carry a Tera Orb. You can find shining crystals scattered around many locations throughout the region.
