Jiralhanae

The Jiralhanae, commonly known as Brutes by humans, are a robust bipedal sapient species native to the planet Doisac and the last species to be incorporated to the Covenant collective. They are known for their incredible strength and durability, and are regarded by many as a savage species due to their territoriality, aggressive tendencies and tribal social structures. The Jiralhanae have an ancient mutual animosity with the Sangheili, originating from nearly a millennium of irregular conflict between the two species in the spinward side of the Orion Arm before the Jiralhanae's assimilation to the Covenant.

Ethnic groups
In addition to the various ethnic groups already present across Doisac, various diaspora populations of Jiralhanae on other worlds have diverged from the species baseline. Notably, most Jiralhanae born on lighter-gravity worlds are taller and less physically robust than their Doisac-born counterparts, which — coupled with the homeworld's harsh conditions — is often used by Doisac Jiralhanae to justify their sense of superiority.
