Ash's Poipole/Personality and characteristics

Poipole is quite playful with other Pokémon. In one instance of this in A Mission of Ultra Urgency!, whilst Ash and his classmates were waiting to see if Buzzwole had been captured, Poipole attempted to play with before flying off. It has also been shown to have a fascination with light, as shown how it tends to stop to admire Pikachu's moves, much like how Ash's Goodra admired Pikachu's strength. In addition, Poipole is known to laugh even when attacked. Poipole took an instant liking to Ash after he helped saved it from Team Rocket. This was also seen when Ash showed it how Poké Balls work. Equally, it also became quick friends with its teammates. Despite being a playful trickster, Poipole never seems to intend any serious harm, as it clearly felt sorry when Pikachu scolded it for poisoning Rowlet, and offered to help carry Rowlet.

Poipole has a habit of spinning on its head when feeling happy. It also likes to express its affection for Pikachu by nuzzling him. Despite Poipole's playfulness, it has been shown to be there for its friends, like in Some Kind of Laziness!, when it rescued and brought back after it was almost blown away by the harsh winds blowing through the Haina Desert. Poipole has also been shown to love making paintings with its ooze, especially of those whom it wishes to be good friends with, like Pikachu and. As revealed in The Shape of Love to Come!, Poipole uses its drawings to express its feelings to others. It draws lighting bolt-shaped marks on or next to things that it likes or loves, and has been seen drawing teardrop shapes when feeling sad.

Being an Ultra Beast, Poipole is quite unfamiliar with the world of Ash and, and is driven by a great sense of curiosity, as seen in Real Life...Inquire Within!, when it began to play with an 's tail head, unintentionally causing the Exeggutor to send Ash rolling out of the Pokémon Center he was in. This same curiosity almost got it in trouble with a on 's family's farm. Poipole appears to lack the ability to smell, as it was unaffected by the stench produced by Garbodor in Real Life...Inquire Within! and reacted with indifference to the aroma produced by the flowers grown by in Some Kind of Laziness!.
