The Galarian legendary birds from Pokemon Sword & Shield's Crown Tundra expansion will roam like Pokemon Gold & Silver's legendary dogs. A Game Informer preview of the new DLC explains that some of the footage shown to press concerned a quest called 'A Legendary Tree of a Legendary Three' in which Galarian Moltres, Zapdos and Articuno fight and then scatter across the Crown Tundra, to be found by players as they explore the region.
