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.
