: I believe that the Locusts were engineered by the COG scientists as a way to fight in the Pendulum Wars.
While I don’t believe the Locusts were created specifically, I believe that the drug was intended to allow soldiers to achieve a far greater physical potential. Increased aggression, strength, stronger bodies (allow for more damage) to achieve a superior army.
However, the results that occurred were not the ones desired. When several of these human subjects started to change, they are kept for observation. Hence, the observation rooms with security turrets.
The female subject that had a different result, I believe is the Locust Queen. The Queen seems more to be a human/locust crossbreed. This lends credibility to a genetic mutation theory, instead of an actual crossbreeding taking place.
When the mutations seemed to be irreversible, the subjects who had completely lost all sanity or humanity were locked into stasis (sires). The few who possibly overcame some of the more drastic mutations, I believe were led to the mountains by the male voice we hear over the loud speakers. Possibly because of the influence of the Queen, possibly because of guilt.
Whatever the reason, we do know that the scientist led a party to the mountains. The Locust Queen and the several subjects left alive built a society deep underground, knowing they would never be accepted by their fellow humans. Here, they discovered ancient ruins. These had been built many years ago, by a species of creatures, known now as Kantus.
High Priests of the, now, Locust Horde, these creatures accepted the transformed humans into their midst. The Kantus are transformed humans from centuries, if not millennia, before their new members. Transformed from living underground, too close to the Immulsion, they were likely early nomads, who sought sanctuary deep underground, possibly to escape a harsh winter. The glowing plants found in the hollow could possibly contain a retro-virus, causing the nomads DNA to rewrite itself, producing more physical changes, and could also be a link to the drug injected into patients at the New Hope Facility.
Trapped, they began to explore. After many generations, the alterations to their physical form became more pronounced. As time went on, the genetic transformations altered their brain chemistry. They became savage as well as confused. They turned to a religion based on what was around them. Worms became idols of worship. The Rift Worm became a symbol of power and commanded their devotion.
When the new humans arrived, the Kantus welcomed them, either realizing that they were transformed humans as well, or because they appeared like them, or perhaps the Kantus were once a kind and helpful race we do not know. We do know that they were accepted.
While the Kantus were mainly a religious sect, the new Locusts were aggressive, due to the experimental drugs they were injected with at the New Hope Facility. These Locust sought power. Elevating their Queen to oversee the entire Horde, they became a Hive mentality.
were mindless soldiers, sent out to inflict the most damage possible.
were larger versions of these drones, and were sent as reinforcements for larger conflicts.
were bred to be a smarter, more adaptable soldier. Able to think on their feet and employ useful strategies, they became the commanders of the Horde Army.
were the only Locusts that were born female. Blind, but enormous, with strength surpassing the Boomers, faster than Bloodmounts, and tougher than Brumaks, Berserkers were used as battering rams. Able to get through any opposition, they were only taken down by the Hammer of Dawn Satellite Weapon.
were part of the original drug trials. I believe they were canine test subjects that the retro-virus altered.
were the first primate subjects. The original form being that of a monkey. Possibly a Capuchin or Spider Monkey. I also believe that the results of the primate trials were slow to surface, due to a seemingly rushed version tested on humans. Hence why Wretches and Sires seem to have similar features.
Thanks to Gearsopedia for this tidbit- “DNA analysis of Brumaks
indicates that the Locust bred them from smaller native apes.” The Locust themselves mutated the Brumaks to what they are today. Possibly gorillas that had been captured by the locust.
act more like vehicles than another form of Locust. They fly by, as yet, unknown means. They consist of large tentacles that act both as legs and weapons. When they die they leave behind an inky cloud. The Hydra (used by Skorge and unknown Palace Guard at the end of Gears 1) is another class of Reaver. Larger and able to support attachment of weapons, they appear to be a favorite for command troops.
are likely larval stages of the Reaver. Like the Reaver, they fly by unknown means and are capable of hovering for prolonged periods of time. They are released from the tail end of a Seeder and accelerate towards enemy targets. How they track their targets is unknown due to the fact they seem to have no eyes. On impact, they cause massive damage. When moving or destroyed, they leave an inky cloud in their wake.
act as a biological mortar. A Drone will insert a Nemacyst into the mouth of a Seeder (the head of which is underground). The Nemacyst travels through the Seeder and comes out the tail end. For unknown reasons, their very presence disrupts communication.
is another Locust of unknown origin. One of the Large Locust breeds; they are unique in that they are intelligent. Able to strategize ambushes, they make several appearances throughout both games. In gears 1, the Corpser tracks our movements while in the Locust Underground. In Gears 2 we see them leap upon a Derrick in the first chapter. Used by Locust to create the massive underground network and to be deadly creatures, these Corpsers have earned their name by the very meaning of it.
have a very vague origin. While they have been seen and used before by the Locust, their exact origin remains a mystery. “Locust use them as Landmines”-Tai Kaliso. The Tickers have a bio-canister that is attached to their back. When triggered, it releases a stream of Immulsion that will explode, causing damage to Human and Locust alike.
are very mysterious. While they are not loyal to the Locust, they appear to respond only to RAAM. In Gears 1, they protected RAAM like a shield during the final battle. RAAM seems to be the only Character able to control the Kryll, as they are likely to devour anything in the dark. Possibly a mutated form of bat, they will only attack in the dark. Even Street Lamps are enough to drive them away. Kryll were eliminated during the Lightmass Bomb in Gears 1.
is a large, deadly fish. It is the only known creature of its kind, although it’s safe to assume there might be others. The Leviathan is killed during Marcus and Dom’s trip to the Hollow. We now know there are several other Leviathans. These have been turned Lambent.
propel the Locust boats on the Cavern lakes. These unnamed fish serve as the engines and resemble an aquatic version of a Reaver with eyes and fins. They are damage resistant like rock worms, able to withstand any and all weapons that are known.
are fairly peaceful creatures. They inhabit the Locust Underground and move through tunnels. A glowing red fruit seems to be their only food source and they are impervious to bullets, their bodies seeming like stone. The only weak spot seems to be their head and tail. Worshiped and eaten by Locusts, they will ignore anything until it gets in front of them.
The Rift Worm
is the Locust Deity. Worshiped by the Kantus, the Rift Worm was apparently woken by Delta Squad detonating the Lightmass bomb. A city sized worm, it is capable of leveling cities, causing them to sink underground. The high Priest Skorge is the only creature able to control the Rift Worm. The Rift Worm would seem to be ancient, as the Locust Religion (The Trinity of Worms) points to a slumber of the Three Great Worms. As these creatures have never been seen by mankind (in recorded history) they possibly have been slumbering for centuries. It is possible that the Rift Worm is a Rock Worm that has grown for many centuries, due to the similarities in appearance.
live inside the Rift Worm. They reside in the layers of the Rift Worm, only emerging to devour any living organisms that enter the Rift Worm. Acting like antibodies, they protect the Rift Worm’s internal systems. Their Origin remains a mystery.
When the Locusts that were living too close to the Immulsion turned Lambent, the Locust organization seemed to turn south. With possible extinction facing the Locust, the Queen could have sent an envoy to the humans asking for assistance. But, since the Locust had been hidden for many years, the COG did not know who they were, and feared they were a new enemy.
Locusts were capturing humans for a very specific purpose. During the Locust Civil War, the Lambent Locust had the upper hand. Losing ground and troops, the Queen sent her Horde to capture humans to convert them. Using the Retro-Virus, they planned to make additions to their army. It’s possible that the retro-virus needs a weak willed host to exist. A Strong willed host could possibly overcome the mind altering effects, like the Queen. The Locust would spend time torturing and breaking humans in order to convert them into soldiers.
Since the Locust were considered an enemy by the humans, and facing the Lambent below was more difficult, the Locust turned to attack the humans for their land instead. Using the worms they worshiped, they tunneled underneath cities, emerging at times to overcome their enemies.
Adam Fenix was captured by the Locusts, knowing he was a scientist. The Queen could have asked him for help to revert to human again, or possibly as a bridge between their two cultures in order to achieve a peace in return for help against the Lambent.
