Private First-Class Arlene Sanders is from the Doom novels, and is the best-friend of Fly. Also a member of Fox Company, Arlene is the Fox Company's best scout, and one of the few people that Fly truly trusts. Like Fly, Arlene gets caught up in the invasion of Phobos and Deimos. Unlike Fly, she uses her scout training to sneak around, and leaves waypoints of sorts, in the form of Arrows marked A.S. She was in love with a fellow soldier named Willhelm Dodd. When they become attacked by the invading forces, she asks Fly to make a pact: If Dodd has become a zombie, that Fly be the one to take him out.
