Alien (Teenagers from Outer Space)

This unnamed humanoid species came to Earth with the intent of using the planet as a grazing ground for Gargons, land-dwelling lobster-like creatures native to their homeworld. Gargons grow to great size and are thus a threat to the aliens. The plan is to relocate Gargons, an essential food source, to another planet from which they can be harvested without threat to the alien civilization.

Biology
The aliens appear externally identical Humans, and are able to survive in an Earth-like environment, although their homeworld appears to have had a smaller amount of nitrogen in its atmosphere than Earth.

Culture and society
The society of these aliens is one where individuals are grown in test tubes not knowing their parents, and raised only by select members of society. Despite this, leadership seems to be hereditary, with the next heir unknown to the public until the time of succession arrives. The government appears to possess a body known as the High Court at one of its highest levels, likely functioning as the top of their legislative branch. Their society teaches that their kind are a superior master race who should not concern themselves with lesser beings. The sick and elderly are killed off for the sake of keeping the species strong. Spaceship crews, often made up of teenagers, are known to readily incinerate any foreign lifeforms they come across. However, a faction of their population has learned of a past that was friendlier and compassionate, with families and siblings, via reading a book, seeking to return to that past. With the death of the heir and leader, it's possible that a revolution will take place resulting, in returning to how things use to be.

Name-wise, the species uses names like Derek, Thor, and Saul, and they have developed a language identical to English. Their numerical system is also identical to that used on Earth, as are their letters. However, Derek had trouble determining what the words on a dog tag mean; which is easily explained in that some aspect of it is not relatable to his society. Family names would be one such factor unfamiliar to him, as his society has eliminated family names.

Technology
The Aliens possess 'Focused Disintegrators'- ray guns that can quickly reduce a target to bone, or cause other matter to catch fire. They consider bullets to be primitive. They utilize flying saucers to travel between planets and have 'radiovision'- where in sound and images are broadcasted wirelessly as a form of two way communication. This is comparable to Human video calling, except it's based on radio waves.

History
At some point in the past, the alien society was one close to common Earth societies, and appeared rather friendly. They would commonly farm and harvest creatures known as Gargons for food, despite the potential threat the Gargons posed. However, their society was then overtaken by an authoritarian regime seeking to make their species into a perfect, supreme race. Traditional family structures were abolished, as was traditional methods of reproduction, replaced with artificially growing new offspring, who would then be raised with no knowledge of their parents or their family. Other methods of unethical population control and indoctrination to an ideology of superiority were also put into action. The establishment of the regime appeared to have been quite violent, with units known as "Annihilators" used to eradicate resistance and other forms of dissent, but certain texts of the time before the regime survived, collected into small books kept by dissidents. The alien regime lasted for many centuries, and by the mid-20th century, the aliens sought to relocate the Gargons from their planet to another habitable world, as the Gargons were posing a threat to their civilization.
