Jiralhanae

The Jiralhanae, otherwise known as the Brutes, were the most recent addition to the Covenant Empire, around the time of the late 20th century. These ape-like creatures are a carnivorous mammalian species that are beyond aggressive and eat the flesh of their enemies, especially after a hunt. During the Great Schism, the Brutes began an uprising with the help of the Prophets to overthrow and destroy the Elites. This brought the downfall of the Covenant Empire in the Human-Covenant War.
