Specials:
Neutral Special: Spirit Shackle - Decidueye takes aim and launches an arrow toward the foe. If hit, the opponent will be stunned and unable to move or jump for a small amount of time, enabling Decidueye to follow up with a strong attack.
Side Special: Leafage - Decidueye launches three razor-sharp leaves out of its wing bow that then spread in a fan pattern. At any point, Side B can be pressed again to make them reconverge for more damage.
Up Special: Brave Bird - Decidueye flies up and then diagonally downward at the peak. If a foe is hit in the downward crash, it does heat damage, but also causes recoil damage to Decidueye.
Down Special: U-Turn - Decidueye gets a ghostly aura about it and launches itself at the opponent horizontally. While in this ghostly state, Decidueye is intangible. After striking, Decidueye goes back to where it was when starting the move. This move doesn't do a lot of damage, and instead is mainly used for its super armor and as a poking move.
Final Smash: Sinister Arrow Raid - Decidueye leaps up and performs its signature Z-Move, Sinister Arrow Raid. A huge line of Spirit Shackles descend from the sky and target the foe, and on impact, explode for massive damage and knockback.
