This drawing depicts the Doom Slayer in a vintage-styled diving suit, based on the divers who explored eerie deep-sea ruins in Lovecraft's stories, such as in "The Temple."
The Doomblade is a harpoon, and the shoulder launcher is an eerie relic inspired by the Old One's arm cannon in Doom The Dark Ages.
