Archfiends

The Elemental Lords in Final Fantasy IV are a group of powerful elemental beings that serve Golbez. They consist of Scarmiglione of Earth, Cagnazzo of Water, Barbariccia of Wind and Rubicante of Fire.

Story
The Elemental Lords are minions of Zemus dispatched under the command of Golbez. As the strongest monsters under his control and the generals of his army, the Elemental Lords were only dispatched against Cecil Harvey after he began searching for a way to become a Paladin. Golbez dispatched Scarmiglione to Mt. Ordeals to kill Cecil, as his undead were immune to Cecil's dark sword. With the assistance of Palom, Porom and Tellah, Cecil defeated Scarmiglione's zombies and dispatched him, forcing him to reveal his true form as an undead himself. However, Cecil prevailed again and Scarmiglione plummeted to his death.

After returning to Baron, the King revealed his true form as Cagnazzo, who had dispatched the true king some time ago as part of Golbez's plan to take over Baron. Once Cagnazzo was defeated, he caused the walls of the throne room's antechamber to collapse as he died, forcing Palom and Porom to petrify themselves to save Cecil.

After agreeing to exchange the final Crystal Golbez needs for the life of Rosa Farrell, Cecil and his companions climb the Tower of Zot and defeat the Magus Sisters, minions of Barbariccia. After defeating them and confronting Golbez, Tellah forced him to retreat when he unleashed Meteor, and both Rosa and Kain Highwind joined Cecil. However, Barbariccia herself emerged to battle them, using strong winds to avoid many attacks. Through Kain's Jump attacks, Barbariccia's storms were overcome and she died, collapsing the tower around her.

With Golbez incapacitated after Meteor and the subsequent battle at the Dwarves' Castle, Cecil and his companions turned their attention to the Tower of Babel and retrieving the Crystals. In the underground portion of the tower, the party confronted Dr. Lugae, who told them Rubicante had always moved the Crystals to the upper portion of the tower. After dispatching Lugae and returning to the surface, they entered the tower with the assistance of Edge and defeated Rubicante.

The Lords were later revived by Zemus in the Giant of Babel, in a final chance to redeem themselves and defeat Cecil. They failed and were once again destroyed.

Etymology
The four Elemental Lords are named after four of the twelve named Malebranches in the 8th Circle of Hell, the Malebolge, from Dante's Divine Comedy.
