He has dark skin and wears a green skull t-shirt. He seems proud of his deformity (webbed toes), which he describes as "like some kind of horrible fish-boy", but everybody gets creeped out when he offers to show it to them. He is sometimes known as "Pooka" in the storyboards. He was named after Roman Dirge, a writer for the show who is also good friends with Jhonen and created the comic Lenore. He was voiced by Danny Cooksey.
