Persian is one of the Pokemon owned and used by Nanu during his Grand Trial with Ash Ketchum
. It was the third Pokémon to battle after Nanu's Sableye
was defeated. It it not the standard size of a normal Alolan Persian and is as big as a Totem Pokémon. Despite never thinking he'd have to use a Z-Move against Ash, Nanu
used Black Hole Eclipse but it was cancelled out by Lycanroc's Continental Crush. That was the turning point in the match and Ash's Lycanroc (Dusk Form)
finished off Persian with an Accelerock to pass the Ula'ula Island grand trial.
