Allister is the fourth Gym Leader Galar Trainers face in their Gym Challenge in Pokémon Shield. This mysterious Trainer became the Gym Leader of Stow-on-Side Gym at a very young age. He is known to have a very shy and fearful around people which is why he wears a mask. The mask serves as a way of confronting his fears and insecurities. He never removes his mask in public. He also keeps about 100 masks with the same design needed in the event his mask falls off. He is rarely seen around in public, preferring to spent most this time alone in ruins and cemeteries. According to Allister, he claims to have the ability to see deceased Ghost-type Pokémon after a supposed accident at the age of four.

League Cards

This is a transcript of the back of Allister's League Cards in Pokémon Shield.

Normal League Card

"He is a young, mysterious Trainer who has taken on the mantle of Gym Leader at a very young age. He has never been known to remove his mask in public. In fact, he has at least one hundred masks of the same design, just to keep spares handy should his mask fall off for some reason. He claims to have developed the ability to see deceased Ghost-type Pokémon after an accident he had when he was four years old, but the truth is still a mystery."

Rare League Card

"This is a photo that happened to capture Allister in his locker room. He can be seen clutching the mask that normally hides his face, no doubt confronting the fears and insecurities he feels within. Even though he has taken the role of Gym Leader at a very young age, it is clear that off the pitch he is still very much a normal boy. However, one mystery remains—nobody knows who took this photo. Some even claim it was the work of Ghost-type Pokémon."

Pokémon

Allister keeps his Pokémon in Dusk Balls.

In Pokémon: Twilight Wings

Allister made a cameo appearance in Letter. He reappeared in Assistant.

In Moonlight, Allister was contemplating in a cemetery and enjoying the full moon when he sensed someone coming, which turned out to be Tommy. Tommy requested Allister's assistance in cheering up his sick friend John by getting him an invitation to one of Leon's matches. Though Allister was too shy to do this, he assisted Tommy in sneaking into John's hospital room so he could apologize for an argument they had.

In Sky, Allister gave his thoughts about Leon in an interview. He also spectated the match between Leon and Raihan together with Tommy and his Pokémon.

In The Gathering of Stars, Alliser was seen with his mask off at the cemetery with his Cursola while enjoying the moonlight while his other Pokémon were seen playing with his invitation letter for the Galarian Star Tournament. He was later seen at Wyndon Stadium, walking out onto the field for the tournament's opening ceremony.
