Ferals are heroes that embrace a savage, animalistic lifestyle or belief system - sometimes a Feral may actually be an animal but in order to qualify they must be of the anthropomorphic kind (such as Tigress), in an environment or world were their savage behavior is seen as abnormal rather than the norm.

Since ferals have a savage and animalistic lifestyle, many of these types of heroes cannot be considered Pure Good. However, they can qualify if they can control their instincts, have a clear moral agency and have no corrupting qualities whatsoever(e,g. Tarzan).
