The Terastal Phenomenon will shake up Gym Battles in Pokemon Scarlet and Violet

Each generation of Pokemon has its own gimmick to shake up the traditional formula of turn-based battles from the original series. Pokemon Scarlet and Violet include the Terastal Phenomenon. In a new trailer, this phenomenon was showcased in a gym battle, showing that players will have to think much harder about which type of Pokemon they bring into these battles.

How Brassius, the new Grass-type gym leader, uses the Terastal Phenomenon

At the beginning of the trailer, Brassius sends out a traditional grass-type pokemon, Smolive. No problem, right? After watching the player character defeat Smolive, Brassius sends his next: Sudowoodo. Fans should know Sudowoodo from Pokemon Gold and Silver. It's a rock-type Pokemon who pretends to be a tree. But what is a grass-type leader doing with a rock-type pokemon? Using the Terastal Phenomenon to change Sudowoodo into "Truleewoodo," as Brassisus calls him, changing his type from rock to grass.
