Dark Carbuncle

A mysterious being that descended without warning, cloaked in an ominous aura. It bears a striking resemblance to Carbuncle and even has the same glimmering protection from all kinds of magic. Although it is every bit as powerful as an esper, it is ultimately an imposter, for where a real esper can be mindful, this creature will wreak havoc based on nothing more than an impulse. All the same, it would take no small amount of power to bring down something so ferocious.
