Joe MacDuff is a Sim introduced in The Sims 3: Supernatural. He lives in Moonlight Falls with his parents, Flint and Joanie MacDuff and his siblings Jules, Faith and Felicity MacDuff. Out of all his siblings, he was the only one not to inherit witch powers, which Jules makes fun of him for. He starts off with no skills and a copy of "Stragedy and Other Messterpieces" in his inventory.
Joe is best friends with his father, Flint MacDuff, friends with his sister, Faith, Mike Nix and his mother, Joanie MacDuff. He is disliked by his sister, Felicity and enemies with his twin brother, Jules, despite the fact that Jules's bio describes the twins' rivalry as being "all in good fun", while Felicity's notes that it was Jules, not Joe, who pulled the prank that traumatized her and caused her hydrophobia.
