Rubicante

Rubicante is a boss in the game Final Fantasy IV. He is one of Golbez's Four Fiends of Elements, and he is the Fiend of Fire. He is considered to be the most powerful of the four, and is the leader. He is also an honorable fighter, and wishes to fight all of his opponents at full strength, despite his being evil. He wears a "Cloak of Flame," which, when donned, protects him from all elemental spells, even those of the ice element. (ice elemental weapons go through though)

Rubicante first appears in the Tower of Bab-il, where he is overseeing the destruction of Eblan, and it is assumed that he lead this attack. He succeeded in destroying Eblan, and he forced its inhabitants to flee to Cave Eblana. He is first seen reporting to Dr. Lugae in the Underworld, and Lugae transports him to the Overworld. There, he is being chased by Edge Geraldine, the prince of Eblan, who is chasing him out of revenge. Cecil Harvey, Kain Highwind, Rydia, and Rosa Farrell catch up to them as they are battling, and they witness Rubicante defeat Edge. Rubicante then escapes.

The party confronts Rubicante again in the upper half of the Tower of Bab-il, where Edge accuses him of not only destroying Eblan, but also for killing his parents and turning them into monsters. Rubicante places all the blame for this on Lugae, however, Edge does not care. Cecil's party then attacks and defeats Rubicante.

Rubicante is revived by Zemus, and, along with Milon, Caignazzo, and Valvalis, fight Cecil's party one last time in the Giant of Bab-il together as four Fiends. However, they are all defeated again.
