Lekgolo

The Lekgolo are a species of sentient colonial organisms in the Covenant. They are called Hunters by the United Nations Space Command. Hunters 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) and a modified Fuel Rod Cannon (Halo 2) 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.

According to Halo 2 the Hunters needed to be "tamed." An Arbiter played a significant role in this event.

During the Civil War of the Covenant, most of the Hunters took the side of the Elites.

Culture
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 were 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, that this was the time of the Taming of the Hunters. 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 a Hunter 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, and a Hunter that has lost its partner can and will become extremely aggressive. Bonded Hunters consider themselves brothers and are fiercely protective of each other. Examples of Hunter names include Igido Nosa Hurru, and Ogada Nosa Fasu.

Hunters seem to be a warring species, though some are known to recite poetry and meditate in their spare time.

Hunters are never seen alone, and are very dangerous as they work and live in pairs.

During the Covenant Civil War, most Hunter pairs sided with the Elite Separatists. No reason for this is yet confirmed, but it is likely due to their deep respect for the Elites, or possibly because the Brutes struck the Hunters first, betraying them. It is unknown if they will follow the Elites into an alliance with the UNSC, since only the Elites are mentioned as being allied with humanity in Halo 3. But given their reverence for the Sangheili, it is likely that some will remain at their side to stand against the rest of the Covenant, possibly alongside the humans. However, the Halo 3 trailer at E3 2007 featured a clip of two hunters firing their fuel rod cannons and in turn being shot by something that resembled a human rocket or possibly a Brute Shot from offscreen, which confirmed the possibility of at least some Hunters remaining as enemies. In the September 2007 issue of EGM, it was stated that there is one part of the level The Storm, where Hunters fight alongside a Brute Chieftain. Given these facts, it is possible that the Hunters have divided loyalties to the Prophets and their religion and to the Elites. It has been noted in the Halo 3 Manual that the Hunters' political motivation is unknown. In Halo: Uprising a number of Hunter pairs are shown both fighting the Master Chief in space and patrolling the city, reinforcing the fact that some Hunters are still with the Covenant. During the Battle on Onyx the Hunters have command of lower ranking Elites.

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.

Hunter Anatomy and Physiology
The Hunter is not a singular organism, but rather a hive creature composed of multiple small, orange, worm-like beings that form a singular collective consciousness and act as one, like a Portuguese Man O' War. 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 worms that compose their body. Hunters have been known to impale careless Marines upon these spines when surrounded. 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 Hunter's physiology, being separated into many singular components, makes it immune to Flood infection, as no central nervous system or calcium stores exist for them to utilize, and single worms are too small to be used as the Flood's tool. Though Hunters are immune from assimilation into the Flood collective, the parasitic race will attack them on sight because their bodies are still viable as food. Many believe that the Flood Juggernaut is an infected Hunter, but this is false due to several reasons.

The Forerunners may have used the Lekgolo to fight the Flood, due to their immunity from infection and apparent presence on a Forerunner planet.

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.

Hunters have three fingers, each bearing a sharp claw. It is said they can grab the players in halo3 with their claws. 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 not move fast enough to run down even a back-pedaling Spartan. 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 the most commonly used anti-Hunter weapon: the rocket launcher. Still, these levels were full of shotgun ammo, and the shotgun is reasonably useful against Hunters at close range.

If you stood 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.
