Deacon St. John is the playable character and protagonist of the 2019 open-world action-horror game Days Gone. He is a biker doing his best to survive in the zombie apocalypse roughly 2 years after the initial outbreak.
William Brodie, respectable city councillor by day and burglar by night in 18th century Edinburgh, was the historical figure who inspired R. L. Stevenson to create Jekyll and Hyde. Although 'Deacon' was his title rather than his given name, he is so well remembered only as "Deacon Brodie" that many people nowadays believe it to have been his actual name.
