Each family member manages a Pokémon Battle Club in a different town or city, providing venues for trainers to engage in practice battles and learn new techniques. Physical distinctions between Don George individuals are minimal, typically limited to collar color variations.

His responsibilities include overseeing daily Battle Club operations and maintaining training facilities. He assisted Ash Ketchum in specialized training sessions, preparing for a rematch against Nacrene City’s Gym Leader Lenora. Don George also investigated a break-in at one club’s storage area, initially suspecting an Umbreon from security footage before discovering a wild Tepig was responsible.

He frequently hosts competitive tournaments, such as the Don Battles Tournament in Raimon Town and the Donamite Tournament in Toaru Town. For these events, he delivers opening declarations, explains rules, announces prizes like feather sets or nutritional drinks, and provides live commentary alongside co-host Freddy O'Martian. He declared Iris the winner of the Don Battles Tournament and presented her prize.

His personality exhibits enthusiasm for discovering rare Pokémon, shown through initial excitement over a potential Umbreon sighting and subsequent disappointment upon identifying it as Meowth. He displays showmanship through his tournament hosting style and prize presentations.
