Similar in several aspects to their normal sized kin, Giant Apes exhibit few changes in comparison. The most obvious being the drastic change in height and weight. The Giant Ape stands over 20 feet tall on average when on all fours. Some have developed bonds with bands and families of normal Apes and take on roles as protectors or guardians of them. Several have formed bonds with Cathar and Leonin Royal Families and act as protectors of cities and palaces.
