Barbariccia is one of the four Elemental Archfiends from Final Fantasy IV. She was in charge of the Tower of Zot, where she was ordered by Golbez to keep Rosa, Cecil's girlfriend, captive, in order to force Cecil to retrieve the crystals for them. Using one of Cid's airships, Cecil enters the floating tower after Rosa and Golbez, so Barbariccia sends her underlings, the Magus Sisters, after him. After they are defeated, Cecil confronts Golbez and Kain, but then Tellah steps in front of them, decided to confront Golbez alone. He uses the forbidden spell Meteor, which doesn't kill Golbez but makes Kain regain his consciousness. Tellah dies, so Golbez leaves the place, since he didn't needed Rosa anymore. Kain guides Cecil to where Rosa was trapped, but as they try to leave Barbariccia stops them, infuriated at Kain's betrayal. Cecil and Kain fight together and defeat Barbariccia, but then the tower starts to fall, so Rosa teleports everyone out. Later on, Zemus resurrects her along with the other fiends inside the Giant of Babil, where they team up to fight Cecil, but even then they are all defeated.
