Mgalekgolo, or Hunters as they are known by Humans, are thought to be giant monsters, but they are actually an assemblage of worm-like entities called "Lekgolo" that create a communal, armor plated form. In this form, they are known as "Mgalekgolo". They always fight and travel in pairs known as "Bond Brothers" which technically means that not all of the colonies of worms were able to fit within one set of armor, and are the strongest of the Covenant fighting units. They wield powerful assault cannons and a massive shield resistant to any small arms fire which may also be used as a melee weapon due to its sharp sides and the Hunters' great strength. They are usually used as weapons platforms, and are only deployed on the battlefield when in need of a heavy force - they are used more like heavy duty equipment than soldiers. Their political and religious motivations are completely unknown.
