Mgalekgolo

The Mgalekgolo are assemblages of colonies of Lekgolo, a species of small colonial worm like creatures, into a larger, more powerful organism. They are commonly referred to by Humans as Hunters.

The most common type of Mgalekgolo is known as a "Hunter", in which the individual Lekgolo form into a vaguely human-shaped creature approximately twelve feet tall, which can then be armed with a Fuel Rod Cannon, armored, and turned into an extremely powerful ground unit. This Mgalekgolo form is commonly employed by the Covenant. When a single colony of Mgalekgolo becomes too big, the colony will divide in half to create two independant Mgalekgolo colonies. These colonies will share an extremely close and mysterious bond, referred to only as being "bond brothers". Mgalekgolo that have split into "bond brothers" are recognized by spiked appendages that rise from their shoulders, which signify the fact that they are bonded to another Mgalekgolo.

It is unclear what other types of Mgalekgolo exist, as Lekgolo colonies have yet to be directly observed outside of combat. However, a strange, orange structure which closely resembles a group of Lekgolo worms has been observed in the core of Scarab walkers in Halo 3, making it a possibility that a Mgalekgolo colony is at the heart of every Halo 3 Scarab walker, though this type of colony has yet to recieve a name

Background
Hunters take a hulking bipedal form in the Covenant military which is, in truth, the least common assemblage of the creatures. In this form, they are the strongest species in the Covenant. These forms stand anywhere from nine and a half to twelve feet tall, but when in their combat state they crouch to approximately eight feet, making their weak spots smaller. Hunters fight with Fuel Rod Guns (Halo: Combat Evolved) or modified Fuel Rod Cannons (Halo 2 and Halo 3) integrated directly into their armor, and they carry an enormous and nearly-impervious metal shield made of an unknown alloy, which they sometimes use as a melee weapon. The modified Fuel Rod Cannon used in Halo 2 is more beam-like, similar to that of the Gravity Cannon. The fire is more sustained, and more devastating. With these weapons and charactaristics it seems that the Hunters are more like equipment then soldiers.

The Hunters' religious, political and philosophical affiliation with the Covenant was based on their need for viable space travel and see little need for religion. When their homeworld of Te was visited by an advanced alien culture who were intent on mining the world, they faced heavy resistance from the Hunters whose physiology gave them a tremendous advantage in combat. Hunters were later forced into the Covenant by the superior starship technology of the Elites - on the ground they were mostly, if not always, victorious. Faced with extinction by orbital bombardment, they joined the Covenant. It is assumed that this is when an Arbiter was killed, and that this was the time of the Taming of the Hunters. Terms for their induction into the Covenant were eventually met despite communication difficulties which hampered the process. As part of joining their conquerors, the Covenant would use local labor and expertise to mine resources from rare metals to minerals. In exchange for this, the Hunters were given free access to the Covenant's spaceways.

Hunters almost never associate, or even communicate, with other Covenant client races, save for the Elites. They are dismissive, scornful, and arrogant to the "lesser" Covenant races, and are utterly contemptuous of their foes.

Hunters have three names: personal name, bond name, and line name. The personal name is given at birth. The line name represents the genetic heritage, being the name of the most successful Hunter of his ancestors. If one reaches a certain level of status, his offspring will have his personal name as their line name. The bond name is taken between bonded pairs, a relationship about which little is known, but it appears to be something like a lifelong brother. Examples of names include Igido Nosa Hurru, and Ogada Nosa Fasu.

In Halo: Contact Harvest, it is stated that Mgalekgolo "Brothers" are two pieces of the same colony of Lekgolo that have formed two Mgalekgolo. One that has lost its partner can and will become extremely aggressive. Bonded Mgalekgolo consider themselves brothers and are fiercely protective of each other.

During the Covenant Civil War, most Hunter pairs sided with the Sangheili and the Covenant Separatists. No reason for this is known yet, but it is likely due to their deep respect for the Elites, or possibly because the Jiralhanae struck them first, betraying them. Sadly, the Mgalekgolo are not seen following the Sangheili into battle against the Brutes during their support of the UNSC on Earth and at Installation 00. It has been noted that the Hunters' political motivation is unknown, although it is thought that if all of the Lekgolo seceded from the Covenant, their homeworld would be glassed.

During the Battle of Onyx, some Hunters had command of lower ranking Sangheili, possibly signifying some sort of leadership or rank level.

They are called mysteries by an Elite Fleet Commander. It is stated that the Hunters were mysteries, and that the commander had known them to tear opponents apart with their "hands" whilst in a blood frenzy, and then pause to recite war poetry.

Anatomy and Physiology
Hunters are not singular organisms, but rather hive creatures composed of multiple small, orange, eel-like beings that form a singular collective consciousness and act as one. The extremely strong armor that covers them serves the dual purpose of protecting the eels and keeping them together. Hunters also have very sharp, long spines made of the same eels that compose their body. Hunters have been known to impale careless Marines upon these spines. However, in-game the spines serve no purpose besides decoration. The white streak on the Hunter's "head" is actually a visor or sensor screen.

The collection of eels that make up a Hunter's body are unintelligent at the most basic level, but can form complex thoughts and emerge as a conscious individual when they combine into larger masses that communicate through chemical and electrical means. Their society is predominated by this combination of being to create exponentially more intelligent creatures, and the actual "Hunter" organism is one of the rarer and smaller forms to be found, used primarily in interaction with the Covenant hierarchy. The eels that make up a "Hunter" only have one eye per worm. The worms that make up the arms and legs have the eyes located within the central thorax armor. The neural net that Hunters develop enables them to be incredibly strong and sensitive to all things within a 1000 foot line pointing out from non-combat form, and a half sphere that extends 500 feet in combat form. Hunters generally growl during battle but will sometimes talk and make remarks like the other Covenant species. Instead of using vocal chords, they vibrate their bodies to make a low rumble that is described as "more felt than heard" to produce speech.

It is theorized that Hunters reproduce asexually; however, there is, as yet, no way to be certain. New information suggests that the Hunters can generate an eel, and then an eel from a large number of other Hunters is needed to make a Hunter.

The Hunters' gauntlets have three fingers, each bearing a sharp claw. It appears that they wear their distinctive arm shield by inserting their hand into a built-in gauntlet. Similarly, their Fuel Rod Cannon has a large hand slot, enabling the weapon to be attached securely to the arm.

Combat
A Hunter's armor is extremely resilient, and is immune to most small arms fire. However, they do have an exploitable weak spot: the exposed orange flesh located in their midsections and necks. While they keep the exposed areas on the fronts of their bodies well-covered with their shields, rarely giving the player an opening unless the Hunter tries to melee them, the creature's backs have a large exposed area that is extremely vulnerable. However, though firearms are incapable of penetrating a Hunter's armor, it cannot stand up to heavy weapons such as rockets and artillery.

In Halo: Combat Evolved, Hunters were rarely difficult to defeat; their AI was simplistic, their shots and melees were slow and awkward, and they could barely move fast enough to run down a back-pedaling Spartan. Interestingly in Halo PC if you don't move from your position while the Hunter is firing at you, it will never hit you with its Fuel Rod Gun. Furthermore, they could be killed by a single shot from the M6D Pistol, as long as it hit the exposed orange area in the middle of the body or the similarly unarmored "neck." Other weapons, especially the shotgun and sniper rifle for very short and very long distances, respectively, were equally deadly. The rocket launcher was always effective, but never particularly necessary. Grenades were only moderately effective, as the Hunter could withstand a half-dozen grenade blasts. Plasma weapons were often ineffective, as was the Needler, and the MA5B Assault Rifle took so long to make a kill that other weapons were far more useful. Still, no player with even a modicum of skill feared confronting a Hunter on open ground. On Legendary, some players regarded Hunters as the least challenging enemies in the game. However, inexperienced or careless players can fall victim to the Hunters' attacks, which, while easy to anticipate, are rather powerful. However, Hunters really gained the upper hand in the cramped hallways of the Truth and Reconciliation and the Pillar of Autumn, where there was little space to dodge the fuel rods or crushing melee blows, and no room to utilize either a sniper or rocket launcher to defeat them. Still, these levels were full of shotgun or pistol ammo, and these weapons are reasonably useful against Hunters at close range.

If one were to stand far away from the Hunter, it would use its fuel rod cannon. However, the shot was slow, and very easy to dodge if you could see it coming. It was also easy to anticipate, as the barrel of the weapon glowed bright green before firing. If you were in melee range of the Hunter, it would also use its arm shield in an attempt to crush you, resulting in serious injury, if not death. However, these attacks were simple to anticipate and dodge. On certain levels, it is possible to defeat Hunters by standing in front of a hole and then sidestepping them as they attempt a melee attack; if timed right, the Hunter will fall down the hole and die. The Hunters have undergone a number of changes for Halo 2. While they appear in fewer numbers, they are tougher and more dangerous. The most notable change is their new weapon: although similar to the old Fuel Rod Gun, the new Fuel Rod Cannon fires a continuous beam of green plasma rather than an arcing projectile. This new weapon is more damaging if not dodged carefully. In addition, the Hunters are over 25% larger and faster, making combat against them much more hectic. Fortunately, all these go towards your advantage when playing the Arbiter; the Hunters are then powerful and durable allies. They have gained a new move, too: the ability to attack an enemy behind them. This effectively makes the old strategy of "dodge-and-fire" far less effective.

Finally, the Hunters have much more health. Most small arms do rather moderate damage against them, in contrast to the M6D's ability to kill them in a single shot. For example, on Normal difficulty, it takes 13 shots from the M6C Magnum Sidearm, 6 full bursts from the Battle Rifle, or 10 shots from the Covenant Carbine to kill a Hunter. On Heroic and lower difficulties, sniper weapons will kill a Hunter in a single shot. However, on Legendary, not a single weapon (except, of course, the Scarab Gun, which is never present during a fight with Hunters anyway) can kill them in one hit. Even a SRS99C-S2 AM Sniper Rifle or Beam Rifle will take two shots to kill a Hunter on Legendary. Often, the most effective weapon against them is the one that does the most damage: the Rocket Launcher is greatly effective, as is the Fuel Rod Cannon. While these weapons take two and three shots respectively to kill a Hunter on Legendary, they can damage one regardless of where it hits it.

Grenades still do little damage against Hunters, and it will usually take a large amount of them to take one down. However, grenades, handheld or fired from the Brute Shot, will disorient a Hunter, giving the player an opportunity to shoot at its exposed flesh. Perhaps the most effective method to defeat a Hunter would be to stick a plasma grenade to it and shoot it in its exposed back with a beam rifle or sniper rifle.

Hunters are equipped with an extremely devastating Fuel Rod Cannon melded into its arm. Unlike a normal Fuel Rod Cannon, Hunters with their cumbersome bulk and strength are able to withstand the recoil and produce a more lasting and lethal blast. If an enemy gets too close, the Hunter will attempt a clumsy but dangerous melee attack with its shield, severely injuring if not killing the enemy. Once its partner is killed, the Hunter becomes much more aggressive and will chase the player, attempting to avenge its partner's death by only melee attacks.

The Hunters in Halo 3 are further upgraded from their Halo 2 counterparts, just as large but appearing less bulky. Their orange areas require far more hits to inflict damage, their previously vulnerable "stomach" areas are covered by armor plating, in addition to performing two new melee attacks in combat, making Hunters more formidable foes than ever. However, their armor now falls off in pieces as the Hunter accumulates damage, and their Fuel Rod Cannon's do slightly less damage, while it appears that grenades and explosives seem to do more damage.

Trivia

 * Hunters were first seen by humans in 2537 in Operation: PROMETHEUS.
 * Hunters are responsible for security aboard a Covenant Warship. One of their duties is to protect the vessel's Ship Master, and, failing that, enact revenge on his assassin.
 * In Halo: Combat Evolved, if you look closely at a Hunter the orange fleshy parts glow in an on and off pattern. This can be seen more easily in a dark place.
 * It is a common mistake to think that Flood infected Hunters become Flood Juggernauts, but due to their physiology, that is impossible.
 * Halo 2 and Halo 3 Hunters will flex their spines upon sighting the Master Chief, unlike its Halo: Combat Evolved counterparts.
 * As of Halo 3, despite the Elites possessing Grunt and Hunter allies of their own, neither appear as anything but an enemy in the game.
 * In Halo: The Flood, it mentions that Hunters have skin and a spine. This is incorrect, however, as they were revealed to be a compound of worm like entities.
 * In Halo: Combat Evolved on the Maw (only on Normal or higher), the Hunters that run out of the cafe room will occasionally have gray stomachs and grayed armor on their back and spines, as well as a "burned" appearance. It is to us unknown if this is just a texturing glitch, a model mix up like the "councilor Honor guard" at the end of Gravemind (level), or to show that the Hunters have been in combat for a long time.
 * One of the easiest ways to kill the Halo 3 Hunters, is a direct hit in the exposed orange back area, with a sniper rifle. this physically weakens them, or kills them. This is a good strategy when your avaliable men are pinned down, or you are short of cover
 * At first, Hunters were meant to comprise the whole of Heretic forces on the Gas Mine.
 * Ophis means snake. Congregatio means assembly, society, union. Translated it means "assembly of snakes", no doubt alluding to their physical structure.
 * In a Bungie Weekly Update, Frank O'Connor said: "Hunter society is complex and we have seen but the tiniest fraction of it. There are some fundamental facts about Hunter biology that mean the combat type is just the tip of the iceberg" . This means, or at least implies, that there are other kinds of Hunters that simply have yet to be seen.
 * Spartan William-043 killed a Hunter by ripping out the worms in its body, hinting that Hunters can be killed if too many worms are displaced.
 * Some say that the Scarab from Halo 3 is actually a giant Hunter. Many things support this.  One is that there isn't a control center on the new Scarab, another is the spotting of Hunter eel's around the control core. Another theory that can support this is that one of the Scarab's main guns appears the same as a giant fuel rod beam, or cannon.
