the brute

The Jiralhanae (Latin, Servus ferox, translated to "Wild Slave"^[1]), also known as Brutes, are a large ape-like species in the Halo series and a member of the Covenant. After the Kig-yar, the Jiralhanae and Unggoy were the second two Covenant species encountered by humans. The Brutes have a profound hatred of the Sangheili, unmatched by any other feud within the Covenant.

The Jiralhanae have been part of the Covenant since before the destruction of the UNSC agricultural colony on Harvest^[2], and were always feared by the Sangheili for their megalomaniacal behavior. The Jiralhanaes' plans to seize power over the Sangheili began with their alliance with the Prophet of Truth during the Battle of Harvest and continued to gain headway until the eventual splitting of the Covenant. They eventually took the role of the Prophet's Honor Guards from the Sangheili after the Sangheili failed to prevent the assassination of the High Prophet of Regret by the Master Chief.

Brutes are of simian origin and have been said to resemble large gorillas, but, in some ways, they also resemble ursine, or rhinoceri as well. They have thick, gray skin, and are covered with matted, black, tan, or brown fur-like hair and some have short, black, or brown colored beards. Their large, stocky appearance is most likely due to the gravity on their planet, which is about twice the gravity of that on Earth. As they age, the hair will change to a grayish-silver color, which is a great sign of respect for all the Brutes.

They have very sharp teeth and sometimes use them as a weapon. Standing roughly nine feet tall, they are immensely powerful even when pierced by multiple bullet wounds (to the point of overpowering a SPARTAN in MJOLNIR armor in hand to hand combat) and fight hand-to-hand if they ever lose their weapon. John-117 barely survived a hand-to-hand battle with one, proving how physically powerful they can be. However it should be noted that John-117 and the other Spartans were suffering from the non-stop combat they had endured since the battle of Reach, with John-117 sustaining, in Doctor Halsey's words, "Burns, brain damage, fractures, and internal bleeding". The other Spartans involved in the fight had sustained various injuries from falling over two kilometers at terminal velocity onto Reach's surface. The Spartans were also in Mark V armor. It appears that their physical strength cannot be accurately quantified.I got this information from halopedia.com
