Decidueye cannot normally be encountered in Paldea, and the Decidueye appearing during this event has Flying as its Tera Type, making it a formidable foe—it even has the Mightiest Mark to prove it! Work together with your friends and keep your eyes open to topple this powerful Tera Pokémon!

This special Decidueye can be caught only once per save data. You can still participate in Tera Raid Battles against this Decidueye to obtain other rewards if you’ve already caught it. This Decidueye may be featured in future events or become obtainable through other methods.
