Alien (Plan 9 from Outer Space)

This unnamed humanoid species are from an unknown planet capable of receiving light from Earth's sun, most likely by seeing the sun as a star. They came to Earth in hopes of preventing the creation of a doomsday weapon that could destroy the universe. They had no intention of conquering or invading Earth, only stopping mankind from creating more powerful explosives no matter what they must do to stop them. The aliens, while having the full capacity to destroy the planet, were exercising alternatives to doing so, with Plan 9 being the final effort.

Biology
The aliens are externally identical to Humans. Most differences in internal physiology are unknown, but they appear to possess at least a similarly-structured pituitary gland.

Culture and society
The aliens appear to be ruled by a single leader, known as only the Ruler. Little is known of his power, but his authority appears absolute. The Ruler is known to reside aboard Space Station 7, and wears a yellow-green uniform with a black sleeveless tunic, bearing the insignia of a shield with a right-facing halberd head on his chest. Military salutes consist of crossing both arms over their chests, their hands touching their opposite shoulders, while military uniforms consist of shimmering purple tunics, gold buttons, a gold belt, and a sideways lightning bolt-like symbol on their left breast. While both male and female soldiers wear the same type of uniform, molded to their body shapes, male soldiers wear a large belt with several saucer-like symbols on it, while female soldiers have a much thinner belt. While the aliens let females serve in their military, females are regarded as second to males, seen more as a means for reproduction than as capable soldiers. This prejudice extends to their military service, with male soldiers known to roughly handle female soldiers deemed to be stepping out of line. Their military is known to have at least nine plans of action for coercing a planet into meeting with or otherwise following the messages of the aliens without a direct invasion, the ninth of which involves creating a massive crisis by resurrecting legions of the planet's dead and directing them to march on important cities. Despite their great destructive power, the aliens speak of having a belief in peace, and a nationalistic pride, primarily seeking the protection of the greater universe and exhausting up to nine plans of least destructive action before turning to warfare. The aliens justify their actions as natural, comparing it to one nation striking against another if the latter threatens to destroy the former. Surprisingly, the aliens have a belief in God, the same God from Earth's Abrahamic religions. The alien language is known to be different from English, but able to be translated, presumably holding some similarities in structure. They were known to see Humans as stupid, citing the fact that Humans resisted the aliens' attempts of contact, arrogantly refused to accept life on worlds beyond their own, and continued making more destructive weapons of war throughout their existence.

Technology
The aliens possess highly advanced technologies in various fields. Their spacecraft, shaped like flying saucers and referred to as celestial ships, can fly across vast distances of space. Their ships make rather loud sounds while flying, and if they fly close enough to the ground, can blow down Humans and other objects not secured to the ground. In addition, they appear to be either protected by force fields or have incredible durability, enough to withstand barrages of anti-air missiles. The material that makes up the ships appears different than Earth metals, making an odd sound if struck. Internal technology is known to be quite volatile, able to make the entire ship catch fire if severely damaged, although even a flaming ship is capable of taking flight. Alien space stations are known to be spherical in shape, with artificial rings around them, used to house and refuel spacecraft. Notably, the aliens are capable of resurrecting recently-deceased organisms through electrodes shot from a their ships into the pituitary gland of the dead organisms, able to make them rise as non-sapient, aggressive, undead beings with enhanced strength and near-invincibility. The aliens are capable of controlling the zombies with electrode guns, both in pistol-like handheld models and devices that appear built into their ships, which can be used to guide the zombies as they move and suppress their aggressiveness, utilizing some sort of electrokinetic beam. The guns must be used on the zombies at all times when they are near the aliens, as the zombies will attack the aliens if allowed to move freely, and it appears that only one gun can be used on a zombie at a time. Contact with metal will break the connection of the electrode guns, and a connection break will cause the zombies to freeze in place. If the guns jam, they will continue to function, allowing zombies to move freely. To destroy zombies, and presumably other organic targets, alien ships are equipped with decomposure rays, which can reduce zombies to skeletons. The aliens have the capacity to destroy entire planets through unknown means, and have either developed or merely learned the principles of a Solaronite Bomb, a weapon that can make beams of light combust, forming a chain reaction across whatever that light touches, which can theoretically engulf the entire universe as the bomb's effects "ricochet" off of stars.

History
The aliens arose in the ancient past, achieving many technological advancements eons before Humans did, becoming an advanced spacefaring civilization. While they developed highly destructive weapons, they set aside their capability of destruction in favor of bringing peace to the universe, only turning their weapons on hostile powers or other civilizations who would otherwise threaten the stability of the universe. As an alternative to immediate invasion of such powers, the aliens developed a group of plans less destructive than warfare, meant to coerce threatening worlds into compliance with disarmament policies. The aliens also knew the concept of light-detonating weapons known as Solaronite Bombs, calculating the massive threat they posed. By the mid-20th century, the aliens observed Earth, and were alarmed by Earth's rapid and reckless advancement in weapons of mass destruction, culminating in the hydrogen bomb. They were even more distressed by seeing that Earth had the capacity to soon discover Solaronite technology, prompting the aliens to contact Earth in an attempt to disarm the planet.

Under command of the Ruler, groups of alien ships came to Earth, with the commanding officers being a male named Eros and a female named Tanna. The aliens sent various messages to Earth seeking to explain their purpose, with some of their saucers being sighted by Humans. The United States even managed to translate their language and make contact with the aliens, but refused to deliver their message to the public, covering up the existence of the aliens. Eventually, there was an incident where an alien representative was shot down, and another where the aliens retaliated by destroying a small town, believing that such would force the Humans to acknowledge the existence of the aliens, although the event was covered up as well. The aliens began implementing various plans to try and coerce Earth into establishing proper contact, but all the plans failed, leaving only Plan 9, involving resurrecting the recently dead to create a planetary crisis that would force world leaders to listen to them. To begin implementing Plan 9, Tanna and Eros, now only in command of three ships, flew to a cemetery, passing by an airline and being sighted by pilot Jeff Trent, the copilot, and a flight hostess. At the cemetery, the aliens resurrect a recently-deceased woman, who promptly kills two gravediggers. They later return when the woman's husband dies, resurrecting him as well, with their passing ship being sighted by and blowing down several Humans. The two zombies soon kill Clay, an aged police inspector.

The last message sent is as follows;

''This is Eros, a space soldier from a planet of your galaxy. I fully realize our language differences, however I also know you finally have perfected the dictorobitary, or as you on Earth put it, the language computer. So you can now understand that which I speak. Since the beginning of your time, we have been far beyond your planet. It has taken you centuries to even grasp what we developed eons of your years ago. Do you still believe it impossible we exist? You didn't actually think you were the only inhabited planet in the universe? How can any race be so stupid? Permit me to set your mind at ease. We do not want to conquer your planet. Only save it. We could have destroyed it long ago, if that had been our aim. Our principal purpose is friendly. I admit, we have had to take certain means which you might refer to as criminal, but that is because of your big guns which have destroyed some of our representatives. If you persist in denying us our landings, then we must only accept that you do not want us on friendly terms. We then have no alternative but to destroy you before you destroy us. With your ancient, juvenile minds, you have developed explosives too fast for your minds to conceive what you were doing. You are on the verge of destroying the entire universe. We are part of that universe. This is our last -''
