Judging from the science fiction of the past forty years, there is no doubt that the Star Zerg has the shadow of the film Alien directed by ridley scott in 1979 and the sequel directed by James Cameron in 1986. They embody highly biological organizations, the concept of drones and the characteristics of the same leader-just like ants in real life. The protoss, on the other hand, is the movie Iron Warrior from 65438 to 0987, which shows the characteristics of advocating honor and belligerence. They first became rivals in the cartoon Aliens vs. Predators in the 1980s, which was also made into a movie of the same name in 2004. 1990 movie "Iron Soldier 2" is a remarkable evidence of their correlation. Finally, the protagonist came to the ship of the predator, with a perverted head hanging on the wall-because the predator has the custom of headhunting primitive people. However, it should be noted that in this set of historical pulses, human beings are helpless, they have little strength to fight back, and they are often just the heads of the other two parties. Philosophically speaking, the racial setting of StarCraft is considered to embody three moral attributes, namely "humanity", "animality" and "divinity".

1. 1. 1 Terran

Terran (or Terran, Tran): The original English word is Terran, which means people from the earth and their colonies on other planets in space. In the original story of StarCraft, all terrans in the original game were criminals exiled by the earth. They came to the other side of the universe in four huge immigrant ships, which means they are not authentic "earthlings". In the whole game series, the only humans from the earth are Gerard Dugard and his earth UED fleet. In the background setting of StarCraft (that is, single-player game), the influence of Terran is not as good as that of Zerg or Protoss, mainly because the scale of human narrative in the story is much smaller than that of the other two races.

1. 1.2 Zerg Zerg

Zerg/Selg (or Zerg): The original English text is Zerg. They have a common creator "Sel· Nagas" with the protoss. Zerg was created as a purely physical creature, so it was also translated into orc. The wisdom, will and strength of the Zerg are concentrated on a few brain worms with high IQ. Other zerg members have no thoughts and will of their own, and they are completely obedient to the hidden energy signals sent by brain worms. In addition, all zerg have a common leader-Overmind, which is the origin of all zerg thoughts, including the chiefs of various tribes, that is, brain worms. The core driving force of the Zerg is the constant invasion and assimilation of other races. They absorb the advantages of other biological DNA and remove its disadvantages, so the life of zerg often has biological perfection. Zerg occupy the largest number of planets among the three families, because they breed rapidly and need few resources. Therefore, the Zerg is the most secret in the story.

1. 1.3 protoss

Protoss/Polotos: Protoss in English. They and the Zerg have a common creator "Xel'Naga", and their home planet is in Ayr. Protoss is a creature created with pure spirit and pure energy, so it is translated into protoss and its civilization is highly developed. Compared with highly adaptable humans and primitive zerg, protoss is more conservative and highly developed in science and technology. Protoss has always considered itself the most powerful race in the known universe. The protoss' reproductive rate is not high, and they can't provide a large number of soldiers for the battlefield like the Zerg, but they know how to use robot technology and combine their super powers to create high-quality soldiers. At first, the protoss was divided into several warring factions, and was later unified by a sociologist and philosopher named Khas (or "the man who brought order" as they called it). According to their ancient traditions and the teachings of their ancestors, they found a crystal called "Khaydarin" to strengthen the natural spiritual connection of the protoss. Khas also formulated a strict religious, philosophical and social structure and named it Khala, which means "the road to ascension". The protoss people abandoned their traditional bloody factional struggle and were very devout to this religion, fearing the infighting caused by violating it. The protoss divided the society into three classes: Khalai (inventor and worker), templar (explorer and warrior) and judge (ruler and leader). Protoss has extremely advanced technology, such as space transmission and plasma shield.

1. 1.4 Xel'Naga

Sarnaga can't be manipulated by players in StarCraft, only mentioned in the game story. Sanaga played a very important role in the evolution of zerg and protoss, and manipulated the evolution of these two races. According to the StarCraft Manual, Sanaga tried to create the perfect race, crossing several galaxies to sow and cultivate countless races. In pursuit of "purity", they created a protoss with perfect form and mental ability on Al. However, after they revealed the plan to the protoss, the protoss attacked it instead, and Sanaga left disappointed. Then, Sanaga turned to create creatures with pure nature. They chose the planet Zerus, created Zerg, and finally attacked Sanaga, killing most Sanaga people.
