Carbuncle

Carbuncle is a summon that appears in several Final Fantasy games. It makes its debut in Final Fantasy V. Carbuncle is usually depicted as being either light blue or green, but is always shown to be wearing a trademark red gemstone on its forehead. Carbuncle has attributes similar to a fox, particularly its long, bushy tail, and it also has a tuft of hair and very long, pointed ears. In earlier games, Carbuncle has three-toed feet and appeared to be bipedal.

Carbuncle's name is shared with the archaic word carbuncle, which means a deep-red or fiery colored garnet or other dark red precious stone, like the gemstone on Carbuncle's forehead.
