Biography
Prior to its time with Ash, Poipole used to live in a peaceful homeworld where it lived with its fellow Poipole and was lead by an elderly Naganadel. The legendary Pokémon, Necrozma, who also resided in that world and was in its Ultra form at the time, gave Poipole's land so much light that it helped flourish all plant life everywhere. Since Necrozma provides light for all the plants, Necrozma became Poipole and Naganadel's sole protector. But then, one fateful day, a meteorite threatened to destroy Poipole's world as it plunges downward from space. Necrozma protected Poipole's world from the meteorite, but it caused it to lose its light and turn into its black form. Necrozma fell into a deep crevice and encased itself into a spiky and crystalized cocoon. Due to Necrozma's black form and lack of light, all of the plants began to wither and Poipole's world plunged into darkness. Poipole and Naganadel huddled into a cave where there are still remains of light left. But one of the Poipole decided to leave its home, hoping to find a better place to live.

Poipole was first seen where it was traveling through the Ultra Wormhole. Sooner or later, Poipole emerged from the wormhole in an unknown area and started to explore Alola. When Ash and the group serve as Ultra Guardians to capture Buzzwole, Poipole witnessed the battle and was astounded by Pikachu's attacks. It was then seen playing around with Pikachu before leaving.

Later, Poipole was enjoying itself flying above the ocean during the night. While it was encountering a wild Chinchou, it recalled witnessing Ash's Pikachu using Thunderbolt attack on Buzzwole and decided to go looking for him, hoping to see Pikachu's electric moves again. Poipole went to the Pokémon School and while everyone was listening to Sophocles' lecture, it got Pikachu's attention and lured him out without anyone looking. Poipole shared an apple with Pikachu and began to show its affection for him. Ash's Rowlet, who was sent to look for Pikachu, mistook Poipole's affections as if it was trying to hurt him. Rowlet dove down to attack the panicked Poipole, but ended up getting poisoned by Poipole's Toxic. After it was scolded for what it did, Poipole apologized as it did not know that Rowlet happened to be one of Pikachu’s friends at first until now, and helps Pikachu carry Rowlet back to Ash.

While traveling through Hau'oli City, Pikachu, Poipole, and Rowlet were attacked by Team Rocket as they wanted to capture them. Luckily, Torracat and Lycanroc arrived just in time to save them before the net caught them just as Ash showed up. After Bewear carries Team Rocket away from Pikachu's Thunderbolt, Poipole was taken to the Ultra Guardians base, where Lusamine analyzed the photos Rotom took, since it was unable to recognize it. Lusamine contacted the group and told them that she, Wicke, and Professor Burnet concluded that Poipole is, in fact, an Ultra Beast, which Team Rocket had already confirmed earlier. They also told them that they chose Poipole as a name it should be identified as. After Rotom updates Poipole's data, Lusamine suggested to have Ash take care of it until they could figure out the location of the wormhole it came out from. Ash made many attempts to catch Poipole with a box full of Beast Balls, but Poipole evaded all of them, thinking he was playing with it. Lillie suggested to have Ash demonstrate how going in and coming out of the Poké Ball works, which he did as he repeatedly sends out and recalls his Rowlet. After that, Poipole understood Ash's intentions and went into the last Beast Ball by itself, much to everyone's surprise. At night, Poipole is shown playing with Ash and his Pokémon at Professor Kukui's house and painted a picture of Pikachu on the wall with its liquid.

Since it joined Ash's team, Poipole helped Ash and his classmates complete several Ultra Guardian missions and helped Ultra Beasts return home.

Sometime later, Poipole traveled with Ash and Pikachu to the Hokulani Observatory on a class trip to learn about the lifecycle of Minior from Sophocles' cousin, Molayne. During the trip, they went outside to take a peak at the Minior shower near Starshower Hill. Poipole become fascinated by it due to the shimmering lights. However, Poipole discovered that one of the Minior didn't break out of its shell. So, Ash and Kiawe carried it back to the observatory. Poipole kept examining the Minior, until the next morning, the shell broke open to reveal an Orange Core Minior. Poipole tried to be friends with Minior, but it accidentally made it upset when it sprayed some of its liquid on it. Poipole realized its mistake and made it up by painting a picture of Minior on the wall with its liquid. Over the course of the day, Poipole and Minior had a wonderful time playing together and becoming friends. During the next night, another Minior shower came and Minior reunites with its kind. But as they start to float back up, they start to fade away into dust, since they can't live longer without its shell. The same fate happened to the Orange Core Minior, which made Poipole very sad. But it was comforted by Ash and Pikachu as they watch the Minior fade away. A few moments later, Poipole caught a glimpse of the legendary Pokémon, Rayquaza flying in the night sky.

Later, Ash and Poipole encountered a trainer named Mina, who is painting pictures with her Ribombee. Mina reveals that Ribombee appears to have the ability to understand someone's emotions including Ultra Beasts. With Ribombee's help, Mina explained to Ash that the paintings Poipole makes is a way of Poipole expressing its emotions to others. She states that Poipole loves Ash and considers him, his classmates, their Pokémon, Professor Kukui, and Professor Burnett as its family. One night, Poipole had a nightmare that revolves in a place surrounded by darkness and filled with multiple sad Poipole as well as a dying Naganadel. The next day, Ash and his Pokémon began to notice Poipole feeling depressed and wondered what its problem is. So, Ash decides to find Mina and ask for her help. After defending Mina from Tupp, Rapp, and Zipp, she reveals to Ash and his classmates that Poipole is on a mysterious mission of some sort. Later that day, Poipole painted a picture that looks like Ultra Necrozma, which is a Pokémon Acerola mentioned back on Ula'ula Island and dubbed it as "The Blinding One."

After working together to restore Necrozma's Ultra form, Poipole's homeworld has finally been restored. But sadly, Naganadel informs Ash that Poipole wants to stay behind where it can protect its kind. Although Ash and Pikachu felt sad at first, but Poipole drew one last picture of them before saying good-bye.
