On the Crown Tundra, four different Pokemon have brand New Galarian Forms. Three of these four Pokemon are the Legendary Bird Trio of Articuno, Zapdos and Moltres. In their Galarian Forms, the Legendary Bird Trio see both stat difference and typing changes. Galarian Articuno is a dual Psychic/Flying Type instead of an Ice/Flying Type, and it's a little bit fast with a much higher Special Attack Stat. Galarian Zapdos is a dual FIghting/Flying Type instead of an Electric/Flying Type, and it flips from a Special Attacker to a Physical Attacker. And Galarian Moltres is a dual Dark/Flying Type instead of a Fire/Flying Type, being much more defensive than its Kantonian Form. Each also receive an Exclusive Move at Level 45, which they will already know when encountered.
The final New Pokemon receiving a Galarian Form is Slowking. Evolving from Galarian Slowpoke via the use of the Galarian Wreath, Galarian Slowking sees a typing change from its usual form. Instead of being a dual Psychic/Water Type, Galarian Slowking is a dual Psychic/Poison Type (just like its counterpart, Galarian Slowbro). On top of this, Galarian Slowking receives a small bump to its Special Attack Stat. Galarian Slowking also has the new move of Eerie Spell, which causes damage to opposing Pokemon and removes 3 PP from the last move they used.
