It fires arrow quills from its wings with such precision, they can pierce a pebble at distances over a hundred yards.
Although basically cool and cautious, when it’s caught by surprise, it’s seized by panic.
It nocks its arrow quills and shoots them at opponents. When it simply can’t afford to miss, it tugs the vine on its head to improve its focus.
Decidueye can nock and fire an arrow at an enemy in a tenth of a second, so its battles are decided in the blink of an eye.
As if wielding a bow, it launches the arrow quills hidden among the feathers of its wings. Decidueye’s shots never miss.
In a tenth of a second, it can nock and fire an arrow quill, piercing an opponent’s weak point before they notice what’s happening.
The air stored inside the rachises of Decidueye's feathers insulates the Pokémon against Hisui's extreme cold. This is firm proof that evolution can be influenced by environment.
