After evolving into Scions, the fluency of their speech increased significantly, at least in one case.

Their written language is also very different.

Locust Speaking Tyran: Although their grasp of the language is usually somewhere in the Hulk Speak to You No Take Candle range.They seem to treat their actions as a case of Do Unto Others Before They Do Unto Us. Not believing that humanity could be trusted to be allies with them, they felt that an Inevitable Mutual Betrayal would happen and decide to commit genocide against their potential enemies. This mentality seemed to arise when they invaded Sera to escape from the Lambent. No matter how much territory or resources they acquire, every breath they take is dedicated solely to destroying the human race.

Kill All Humans: This seems to be the only reason for their species' existence.

Invading Refugees: Downplayed - while they were losing ground to the lambent in the Hollow, revelations in Gears 5 indicates Myrrah would've eventually invaded the surface anyway to get revenge on mankind.

Gears 5 seems to indicate that the Locust reproduce fairly normally, so this isn't due to them not having children.

Hide Your Children: Lampshaded by Baird, who remarks in one of the collectible intel items that it's strange despite fighting straight into the heart of the Locust civilization, there are no Locust children running around to shoot.

Elaborate Underground Base: Their capital city of Nexus.

Dark Is Evil: Locust forces have a penchant for dark colors on their armor.

And this is for those that don't meet up with the Locusts' standards! Those that do? They get turned into new Locust Drones.

Cold-Blooded Torture: 'Processing', which involve beating a person with a bladed whip, as well as many other forms of torture, and ends with lobotomy.

It caused them to undergo a 25-year-long evolution process that turned them into the more powerful Scions.

Came Back Strong: Turns out Adam's weapon didn't kill the Locust after all, or at least not all of them.

Gears Tactics reveals that these masks were designed by Ukkon, and are how the Locust control their creatures.

Cool Helmet: While some Locust wear interesting looking helmets, it's far more prevalent among their Beasts Of Battle, almost all of which wear specialized masks.

We've tagged them Locusts since this degree of death has only been seen in times of plague. Scientist: Frankly, other than the fact that they want to kill every man, woman and child out there, we know nothing about them. Summed up nicely with the following quote from an anonymous scientist who first named them. In fact, the only reason they were called Locust was because humanity knows nothing about them and the amount of death and destruction they cause can only be associated with some type of plague.

Call a Smeerp a 'Rabbit': Despite their name and hive societal structure, they're very clearly not insects.

Initially carved out by the Riftworms and corpsers, the Locust gradually expand it to contain their entire civilization.

Beneath the Earth: The Locust Horde lives in a massive tunnel network beneath the surface of Sera known as the Hollow.

They're descendants of humans who were afflicted with Rust Lung (an early form of lambency), who were genetically spliced together with the DNA of Hollow creatures by rogue COG scientists to create a breed of Super Soldier to win the Pendulum Wars.

Belated Backstory: We only really learn their true origins in Gears 5 and Gears Tactics, long after the majority of the Locust Horde either went extinct or became the Swarm ( Tactics may occur during the war, but it is a Prequel).

Bee People: Locust society is structured with a Queen at the top, and lots and lots of disposable drones.

Always Chaotic Evil: They're vicious monsters who regard humans as mere cattle.

Their motives for this were revealed in Gears of War 3: the Lambent were overwhelming the Locust in the Hollow, and after Adam Fenix failed to find a solution, Queen Myrrah invaded the surface to make a new home for the Locust as they continued their war, not believing that humanity could be trusted.

The Locust invaded the surface of Sera six weeks after the end of the Pendulum Wars, beginning a war that would result in the death of 99% of the human population. They use a variety of bio-engineered beasts for transport, construction, and war.
