Drinniol

Drinniol, known to the UESC Marathon's crew as "Hulks", are cyclopean sapients standing over ten feet tall. Having nearly no fat throughout their entire bodies allows them to be immensely powerful but at the same time has the drawback of forcing them to constantly eat or risk perishing. Being as strong as they are, they are capable of easily killing a Human with their bare hands. Slow-moving, they are nevertheless deadly at close range due to their heavy crushing strikes with the claws on their arms. Since humanity only seemed to notice them twice on the Marathon, and both in BOB-heavy locations, it has been assumed that their masters, the Pfhor, likely only utilize them to gather potential prisoners. Even so, two ranks of Drinniol are known to be utilized during Pfhor campaigns, the Minors and the Majors. They have green blood.

Another species known to another group of Humans, found within an entirely separate group of invasionary extraterrestrials known as Covenant]], are known as the Drinol and are very likely actually the same species.
