Moon's Decidueye (Japanese:ムーンのジュナイパーMoon's Junaiper) is aPokémon thatMoon owns in thePokémon Adventuresmanga and her fifth overall. Moon received him fromProfessor Kukui. He is at least level 16.
Decidueye first appeared as a Rowlet inThe Delivery of Rotom and the Girl.Professor Kukui was seen testing Rowlet andPopplio's moves in his lab, causing a ruckus that sent all three flying through the roof and onto the beach, where they met Moon andSun. While Sun introduced Moon to Kukui, Popplio sneezed, trapping Rowlet and Kukui in its water balloons. Though Moon immediately freed Kukui with one of her arrows, Popplio had to remind her to also rescue Rowlet. Due to spending so much time in the bubble, Rowlet developed a cold and had to be healed with Moon's medicine. Afterward, Rowlet took a liking to the girl, the two forming a bond because of their mutual preference of nighttime.
InThe Decision and the Tournament of Six, Rowlet traveled with Moon toIki Town, where a festival was being held. Later, he helped rescueNebby from being attacked by a group of wildSpearow atMahalo Trail. Due to the battle being three-on-one, Rowlet was unable to win, but managed to distract the Spearow long enough for Moon to get to Nebby.
InGoing Ashore and Neighboring Akala Island, Rowlet was attacked by a pair ofTeam Skull Grunts as he was seeing Moon, Sun, and Kukui head off toAkala Island. By feeding him aSalac Berry she fired with her bow, Moon raised Rowlet's Speed enough to escape the Grunts and fly into Moon's arms. Afterward, Kukui noticed Rowlet liked Moon and suggested she keep him, which she accepted.
InDefeat and the Commander of the School of Fish, Rowlet was used to battle aXurkitree that attackedTapu Lele atLush Jungle. Rowlet kept Xurkitree distracted long enough for Moon to shoot aPoké Ball-tipped arrow at it. Though Xurkitree escaped being captured, Tapu Lele was freed from its grasp, after which it angrily flew off.Afterward, Rowlet, the rest of Moon's team, andMallow'sSteenee helped find aMirage Berry for Sun to give to Tapu Lele. By asking the local Pokémon of the area, Moon was able to quickly gather a large group of Berries and successfully find the one she was looking for.
InTruth and the Mastermind Behind Team Skull, Rowlet transported Moon toPo Town, where they clashed against theUltra BeastsGuzma summoned toAlola. Rowlet was later used to try and stop aNihilego from kidnapping Guzma. Their attempt was stopped by Xurkitree, which grabbed Moon, allowing Nihilego to drag Guzma into anUltra Wormhole with it. Moon and Rowlet were rescued by Sun.
After Moon exited Ultra Space, Dartrix and the rest of Moon's team were stolen byFaba and stored atAether Paradise in Secret Lab B. InRegeneration!! The Power of the Sun and the Moon!, after Moon escaped Faba, she headed to Secret Lab B and found Dartrix and the others safe. While trying to prepare medicine forGladion, Moon was ambushed by Aether Foundation Employees and had her team hold them off while she finished her work. While battling against aHuntail, Dartrix evolved into Decidueye.
Decidueye is normally laid-back and easygoing, but takes on a more serious personality when battling. He is quite strong, and when first introduced, was shown destroying a part ofProfessor Kukui's house alongsidePopplio. Despite this, he is weaker during the day due to being nocturnal, needing to store up his energy to become active at night. Decidueye has a close bond with Moon, formed on the day they met when she helped him recover from Popplio's Bubble Balloon. The two grew so close in such a short time that Rowlet refused to leave Moon and chased after her when she left forAkala Island.
