In South Park: The Stick of Truth, Big Gay Al has no role in the story and only appears on a cellphone lodged inside of Mr. Slave's anus when The New Kid is forced to go inside it to disarm a snuke. The New Kid has a few seconds to answer it and befriend Big Gay Al on Facebook.
In South Park: The Fractured But Whole, Big Gay Al will be physically present inside his own house (Big Gay Al's House), sitting in the living room next to his partner Mr. Slave. He will give The New Kid a quest to retrieve back all of his lost cats on the second day in-game. A selfie can be taken with him after successfully returning all of his lost cats to him.
