Mgalekgolo

The Mgalekgolo[2] (Ophis congregatio, meaning "The congregation of Ophis (Ophis being Οφις in Greek: meaning Serpent)"), more commonly known as Hunters, are a unique gestalt of smaller creatures known as Lekgolo, which are tiny, orange, worm-like creatures that group together to exponentially increase their intelligence, strength, and maneuverability. During and after the Great Schism there was a division within the species, some aligning with the Covenant Separatists and others remaining with the Covenant Loyalists. They almost always come in pairs or "bond brothers." The death of one will enrage the other if it witnesses the other's death, except in Halo: Reach.
