Trivia

• Allister shares his Japanese voice actor, Ryō Hirohashi, with his counterpart from the Pokémon: Twilight Wings miniseries.
• In his sync pair story, Allister says that he had a near-death experience when he was four years old, and he believes he came back to the land of the living through a Gigantamax Gengar's mouth.
• All versions of Allister use special voice-over lines upon entering a team that contains certain Trainers (regardless of their partner Pokémon). Those Trainers include Agatha, Morty, and Phoebe.
  • Allister also uses special voice-over lines upon winning a battle with Morty in the same team.
• Allister & Gengar are the only sync pair whose expedition skill has been changed through an update; prior to version 2.27.0, their expedition skill was "Fiery ↑ 3 Soothing ↓ 1".
  • Prior to version 2.27.0, they were the only sync pair whose expedition skill lowered the discovery level of their role's crystal; in their case, it lowered the discovery level of Soothing Crystals despite being a Tech sync pair.

Origin

Allister's design is based on his appearance in Pokémon Shield. Gengar is Allister's signature Pokémon in the core series games, where it is also capable of Gigantamaxing. Gengar's Dex entry comes from Pokémon Ultra Sun.

Allister is not seen owning a Gourgeist outside this game. Gourgeist's Dex entry comes from Pokémon X.
