Ash's Rowlet was obtained in the forest near the Pokémon School on Melemele Island. It is an easygoing glutton that still exhibits incredible amounts of power when fighting for its friends. It enjoys roosting in Ash Ketchum's backpack and is often seen there while traveling.

It hatched from an egg with a group of Pikipek and despite the Pokémon type difference, it became a well liked family member of the nest which also included a Trumbeak and a Toucannon. It would often go on food scavenges with the flock at a certain time of the year. It had mistaken a wind chime for a berry and it had to go out again to find food but the second time it went out it mistook Mallow's Bounsweet for food as well. Ash Ketchum though took pity on it and gave it some food including a watermelon which Rowlet took back to the nest and was congratulated for bringing. Ash Ketchum though wanted to catch the Rowlet, so he followed it back to the nest. When Ash Ketchum decided that it should stay with its family in the nest instead of trying to catch it, Toucannon nudged Rowlet out, telling it to go with Ash Ketchum. Moments later, it let itself be caught by the Poké Ball.

Grand Trial battle vs Hala's Crabrawler

During the Grand Trial battle against Ash's Rowlet, Crabrawler was at a disadvantage due to the types. Rowlet was able to use the smokescreen from Leafage to surprise Crabrawler and Peck it from behind to have a successful counterattack to all the previous attacks. That was the turning point in the match as Ash's Rowlet won the match but fell asleep while flying as it got too tired from battling.

Alola League

The Second match of the Alola Pokémon League quarterfinals featured Hau's Decidueye verses Ash's Rowlet. Just before the battle, Toucannon and friends brought Rowlet a cape and helped it learn the move Feather Dance. Both of them used their Z-Moves early on in the battle but the ferocious, heated battle continued on. After Brave Bird and Sky Attack clashed, it looked like Ash's Rowlet had lost the match and Nanu had actually called the match but the chief referee Hala realized that Rowlet hadn't been knocked out yet and was just sleeping, so they continued the match and Rowlet mastered using Feather Dance to avoid a Sky Attack and countered with another Brave Bird to come from behind to win the match.

In the Alola League Exhibition Match, Ash's Rowlet was the next opponent to face Braviary after it had defeated Lycanroc and the match turned into an aerial battle with Braviary’s chasing Rowlet and using Steel Wing at the same time. While up in the air, Rowlet continuously used Seed Bomb and it had Braviary completely at its command for quite awhile until a Steel Wing has finally connected. Rowlet used Brave Bird and defeated Braviary.
