In the Halo video game series, a Hunter (also known as Mgalekgolo) is a formidable and powerful enemy species encountered by the player. Hunters are part of a species composed of a bonded pair of worm-like creatures called Lekgolo. These Lekgolo worms are massive and robust, making them capable of forming a symbiotic relationship known as a "bond brotherhood." When bonded together, they create a powerful and heavily armored bipedal organism called a Hunter.

Hunters are characterized by their immense size, towering over regular infantry units and most other enemies in the game. They possess heavy, reinforced armor that provides significant protection against various types of attacks. Additionally, their combat abilities are formidable, making them challenging opponents for players to defeat.

Each Hunter is equipped with a unique heavy weapon called the Assault Cannon, which functions as both a devastating long-range cannon and a melee weapon at close quarters. Their formidable firepower and resilience make them one of the most dangerous adversaries in the Halo universe.

In-game, Hunters are typically encountered in pairs or groups, often acting as shock troops or guardians for important assets or installations. They are featured prominently throughout the series, providing thrilling and memorable encounters for players as they strive to overcome these intimidating foes.
