This shining fairy Esper uses its red eyes to cast Reflect on the party.Final Fantasy VI PlayStation esper section
Carbuncle is a small, rabbit-like blue creature. It has a red gemstone perched on its forehead.
Carbuncle was one of several espers captured by the Gestahlian Empire during their first raid on the esper world. The captive espers were taken back to the Magitek Research Facility at Vector, and for sixteen years they were experimented on and had their magic drained to develop the Empire's Magitek army.
When the Returners infiltrated the facility and shut down the machinery draining the espers, they were too late to save them. With too much of their energy drained, they transformed into magicite and entrusted themselves to the Returners.
Carbuncle has utility throughout the game if the player needs Reflect on the party, as there is no other skill that offers such a thing. It can be particularly useful in the Cultists' Tower where many enemies have innate Reflect status.
Carbuncle teaches many useful utility spells. With the exception of Reflect all of them are taught by other espers and at higher learn rates, but several of these espers are not available until the World of Ruin. It is also the only esper to teach Reflect.
Carbuncle was a mythical creature reportedly sighted in the Americas by Spanish conquistadors. It is described as a small creature, either a bird or a mammal, that has a gem in its forehead crystallized from the brain of a dead dragon. According to myth, it is good luck to catch a carbuncle. A carbuncle is also an archaic name given to any red cabochon cut gemstone. The name applied particularly to red garnet.
