Gluttony has a unique metabolism that enables it to store a nearly infinite amount of energy. It can consume anything, and is able to digest it with the concoction of super acids in its stomach. A young Gluttony can consume enough energy to last an entire lifetime in its earliest stage, but unfortunately, has no mechanism to alert it when it is satiated. As a result, Gluttony eat purely for fun, and if left unchecked, will destroy entire ecosystems by consuming everything in sight.
