Along with its previous effect, Flower Gift now changes Cherrim from Overcast Form to Sunshine Form if the weather becomes harsh sunlight while Cherrim is in battle, or if Cherrim is sent into battle while the weather is harsh sunlight. If Cherrim loses Flower Gift or Flower Gift is suppressed (such as by Gastro Acid), it will revert to its Overcast Form, unless it was Dynamaxed at the time; if a Dynamaxed Sunshine Form Cherrim loses Flower Gift, it will remain in Sunshine Form even after it ceases to be Dynamaxed.
Although Abilities do not occur in gameplay in Pokémon Legends: Arceus, Cherrim's Sunshine Form has boosted base stats in this game only, to simulate Flower Gift.
