Gorilla

Gorillas are large apes that are native to Africa. They are typically divided into two groups. The mountain gorilla lives in the mountainous regions of central Africa, while the lowland gorilla lives in the flat, dense forests of central and western Africa. Though the two types are very similar, they have a few differences. For example, mountain gorillas tend to have longer hair, whereas lowland gorillas have short, soft hair, according to the Smithsonian.

Description
The Gorilla is the largest of the great apes and one of the closest living relatives of the human species. The Gorilla is a strong attack unit at a relatively modest price. With the massive pummeling arms and a furious bite, it is the most powerful primate available. Unlike the other great apes, Gorillas travel, eat, play and sleep in the stable family groups. Because of this, they receive a defensive herding bonus when 4 or more are in close proximity to one another. When combining, keep in mind that this creature has a high attack rating, but a relatively low defense rating.
