Priest Maxi wears a black robe with a white collar strap, black pants, black shoes, and black reading glasses.
In South Park: The Stick of Truth, Priest Maxi will be seen outside South Park City Hall, sitting on a bench while reading a book.
In South Park: The Fractured But Whole, he will be found inside South Park Church, sitting on the front most pew, next to the church's podium. When South Park Church is entered for the first time in-game, Priest Maxi will preach to The New Kid that South Park is in terminal decline, and that The New Kid seems divided between good and evil; he then proceeds to ask The New Kid to enter a 'meditation room', which ends up with The New Kid confronting against two pedophile priests.
After defeating the pedophile priests, Priest Maxi will proceed to present The New Kid the Macaroni Picture Summons item; a selfie can also be taken with him.
On Day 4 in-game, after The New Kid leaves home, Priest Maxi will make a video call to The New Kid, advising The New Kid to head to Stark's Pond to seek what The New Kid is spiritually.
