Yeerks

The Yeerks were a race of parasitic creatures. Visually they resemble worms. They are capable of entering a body through an orifice, usually the ear canal to reach the brain, upon which they take control of the body, which is dubbed as a "Controller".

## **History**

### **Pre-Earth Invasion History**

The origins of the Yeerk are unknown but they originated from a planet dubbed Kandrona, as they require Kandrona rays specifically to gestate. They largely could only live in small ponds later called Yeerk Pools. It is believed that the Celestials visited their planet long ago and like with most races they encountered, caused an evolutionary split. This resulted in the Goa'Ulds, who departed to seek out conquests in the universe, forgetting their origins as time passed. Before that point the Yeerks are believed to have been known as the Yoorts. The Goa'Ulds attempted to bring the Yoorts with them but found the Yoorts had developed a condition where they could not survive outside the rays of a Kandrona sun and so were dumped on a planet in the Kandrona system as the Goa' Ulds continued forth.

The Yeerks were not alone on the planet, which contained a blue ape like species called the Gedd. The Gedd evolved bizarrely, lacking much intelligence, and possessed difficult to control motor functions. Because of this, they became the first race the Yeerks infected, entering into a symbiotic relationship.

They lived this way limited by their reliance on the Kandrona rays and the aspects like the weak vision of the Gedd until the arrival on the planet by Prince Seerow, who led an Andalite expedition to the planet. Seerow pitied the Yeerk and provided them with Andalite technology, including teaching them writing and astronomy. This wound up backfiring horribly when the Yeerks, fueled largely by the realization of just how large the universe was and what they lacked biologically, launched an attack on the Andalites in the Earth Year of 1966, sparking the Yeerk-Andalite War. The Yeerks would destroy the Andalite where they found them. For his actions, Prince Seerow was exiled to the planet of Hork-Bajor, A new law was passed by Alloran-Semitur Corrass called "Seerow's Kindness" which forbade the Andalites from sharing their technology with other species. The Yeerks went on to form the Yeerk Empire in 1968. They then went on to conquer another species called the Nahara.

The Yeerks created artificial Yeerk Pools to feed and reproduce while on their conquests. One of the first planets they aimed to conquer was Hork-Bajor due to the information that Prince Seerow was exiled there from infected Andalites. The planet's native species was a reptilean race. They were pacifists by nature, the Celestials had visited the planet and caused a split into another species which simply called themselves "The Race" and departed the planet to become conquerors. The original race had been created by the birdlike Arn which planted trees on the planet and created the original Hork-Bajor to protect the trees. The Yeerks arrived on the planet and to make them their first conquest. They believed they were fierce warriors and enslaved them for that purpose. The Yeerk Esplin 9466 was the first Yeerk inserted into a Hork-Bajor body. His first words were to declare the species their foot soldiers, resulting in the attack. Prince Seerow was among the casualties of the attack, despite his death the Yeerks retained a positive view of him as "The One Good Andalite". War-Prince Alloran-Semitur-Corrass unleashed the Quantum Virus on the planet in an effort to kill the Yeerk infected Hork-Bajor while sparing the uninfected. Despite this, the planet and the species was largely enslaved.

Several other factions, including the Galactic Federation, led largely by the insect- like Gromflomites, The Vulcans, The Nova Corps, and the Green Lantern Corps joined the battle against the Yeerks, which were aided by the Goa'Ulds and the Furons. Yeerk attempts to infiltrate Hala, Remulak, Ork and Mesklin. The Planet Ceti Alpha 5 in particular was devastated by the Andalites to prevent Yeerk assimilation, resulting in a great loss of life, which angered the Vulcans into departing the alliance. Despite the assault Yeerks on the planet would survive and evolve into a more violent feral species.

The Yeerks then encountered the Taxxons, who were a caterpillar like race with an uncontrollable hunger. Because of this the Yeerks hated controlling them and instead made a deal with them to allow them to be controlled in exchange for a steady source of food. They then began their path for conquest.

The Yeerks infested the Ongachic, a race of nomadic Klingons who preferred life as artists and musicians. They had left the rest of their species long ago and had no memory of it that the Yeerks could use to find the rest, sparing the Klingons from an invasion. The Yeerks also conquered the Garatron race and then the simply titled "The Race" warlike descendants of the Hork-Bajor.

### **Earth Infiltration(1991-1999)**

The Yeerk Edris 562, picked up a signal from two humans, the first time they encountered the species. Hedrick Chapman and a girl named Loren had been abducted by a race called the Skrit Na for experimentation before the Andalites rescued them. Yeerk Edris 562 was stationed at Hork-Bajor and broke orders to investigate the detected presence with the Yeerk Essam 293, leading to the discovery of Earth in 1991. They crashed during the gulf war and saw the United States soldiers emerging victorious. After receiving picking up transmissions, including reruns of Galaxy Quest, they chose to travel to Vinewood due to the number of times it was mentioned in the transmissions they received with the other potential candidates being Washington D.C., Metropolis and Los Santos. The first two Yeerks to arrive on Earth, Edris 562, and Essam 293, infested an actress named Jenny-Lynne Cadwalader, and the Producer Lowenstein. Both would switch bodies to Allison Kim and Hildy Gervais respectively. The two had human children named Maturin and Madra and came to believe they would never be accepted back into Yeerk society but suffering from Kandrona withdrawal as the artificial pool faltered, Essam 293 allowed themselves to die while Edris 562 made contact with the Yeerk Empire and began the covert infiltration of Earth.

Edris 562 looked into Earth's history and learned of the many failed invasions and alien encounters, such as the Molluscs, The Triffids, The Kanamits, the Pod People, The Zygons, the Skrulls, and the Visitors. Realizing that an invasion would need to be more subtle to succeed, Edris 562 was promoted to Visser One, but clashed with Visser Three, A Yeerk who had taken the body of Alloran-Semitur-Corrass and who wanted direct invasion. They formed an alliance with the Furons. Edris 562 created a group called the Sharing to welcome in willing hosts. The Sharing was based on groups friendly towards alien like the Keith Winton’s Church of Practiology and Valentine Michael Smith’s Church of All Worlds. Lancaster Dodd and his own group the caused attacked the Sharing, leading to the religious elements to be faded out. The Yeerks worked to studying and developing counters to elements such as Superheroes and the supernatural. They began to work towards infiltrating the Magical world.They found their opening when Ellen Cracknell joined the sharing. Cracknell has two children with a wizard named Orford Umbridge. In a divorce they had each taken one child with Cracknell leaving England for America. Cracknell was infested with a Yeerk and tracked down Orford Umbridge, who had been cut off from his daughter Dolores Umbridge, who had deemed her father as detrimental to her own career and fashiond a fabricated backstory for herself. Orford Umbridge was infested with a Yeerk and got close enough to Dolores to infest her as well.

The now Yeerk infested Umbridge(Who's name was never discovered) began to work towards categorizing the magical species or containing them, in order to determine their viability as hosts for other Yeerks. Several members of the Ministry of Magic were infested and more would have had it not been, ironically, for the revival of Lord Voldemort, who captured Umbridge and in the process learned of the Yeerks and was impressed, pulling out the creature from her brain.Voldemort threatened to kill the Yeerks but saw their potential use, instead choosing to limit their spread so long as they worked closely with him in exchange for providing hosts, likely intended to be Muggles. Umbridge, under Voldemort's service, sent Dementors after Harry Potter in 1995, but he repealed them and was placed on trial before being forgiven. Umbridge did briefly take over as Hogwarts Headmaster to spread more Yeerks, clashing with Voldemort during this time in a secret civil war, which ended when Umbridge was abducted by Centaurs, which reminded her of the Andalites. The Andalites as it happened , had made contact with Earth and had some knowledge of Yeerk infiltrations but understimated the extent, making contact with the Centaurs in secret. the Yeerk was removed from Umbridge and she was released, working with the Ministry to remove the infected Yeerk presence to save her reputation. This was kept hidden by the Ministry to avoid a scandal. When Voldemort took over in 1997, Umbridge saved herself by pledging loyalty to Voldemort and claiming to have helped remove the Yeerk threat from his rule.

The Yeerks began looking to infest other planets in the Solar System. They discovered Mondas on the way but found the inhabitants had been roboticized, making them unfit candidates. An attempt to take the planet Mongo was repelled. Encounters with the Mi-Go and the Ganymedans led them to be declared unsuitable for hosts due to the odd makeup of their bodies(Fungus and wormlike respectively). They also encountered the Vermicious Knids, which attacked them on site, sparking a war which occupied Visser 2, who made only a brief attack on Earth attempting to start a nuclear war between the US and China. They also attempted to conquer the Moon and Mars. The Mars efforts were thwarted by the large headed species present on the planet. They saw more success against the Lunites on the Moon and infiltrated several of the species there including the Selenites. While they found the remains of the Silver Millennium they were pushed back by both the Attilans and a Nazi Moonbase, leading to their defeat.

The Yeerks conquered the Mak, the Ssstram, sometime shortly before the invasion of Earth. At the time they were invading Earth, they were also making plans to invade the amphibian froglike race of the Leerans on their home planet of Leera. Due to Leeran telepathy they were working on studying marine creatures on earth in order to gain a better understanding. This attempt was thwarted when the Yeerk invasion fleet was devastated.

The Yeerks had infiltrated close to 60 million people by 1995. It was 1996 when Earth became aware of their presence. The Andalite Dome Ship Galaxy Tree was sent to Earth but was ambushed from behind the moon by Visser's Three's ship, The ship crashed on Earth with Four survivors. The Andalite Elfangor granted five humans in Bahia Bay, California, the ability to morph and the group started a guerilla campaign against the Yeerks. U.N.I.T. learned of the Yeerks when they attempted to infect Diana Palmer. At the time there were multiple devastating alien invasions including the recent threats from the Eugenics Wars and the Brotherhood of Nod as well as invasions from the Harvesters, Martians and Fithps. This diverted much of their attention. The Yeerks worked alliances with the invaders but met with no success though they gained the aid of the Furon faction known as the Exalt, who were infiltrating Earth through the Syndicate of the Men in Black. It was through the Syndicate the Exalt became aware of the Yeerks in 1997. Seeing potential use, the Exalt worked to conceal the SCP Foundation and Torchwood from learning of the Yeerks to expand their own power. Stargate Command learned of the Yeerks but falsely believed they were members of the Goa-Ulds, though they shared ancestors and were allies.

The Yeerks prioritized taking California, having falsely believed it was Earth's capital at first and it housing the Animorphs, which were the only beings on Earth which could expose them. It was also the location of the Sharing, meant to spread the Yeerks to its members. The Yeerks attempted to infiltrate Sunnydale but the Mayor of the town Richard Wilkins, though a member of the Sharing, was also a sorcerer who had made deals with Demons. The Yeerk was forced out by the Demons, who told him that they had "called dibs". Wilkins threatened to expose the Yeerks unless they got out of Sunnydale, which they did. The Yeerks infiltrated White Supremacy groups to create chaos including Earl Turner's The Order. The Yeerks also attempted to infect the leaders of a G8 Summit in San Diego including the US's Josiah Bartlett, UK's Adam Lang, Russia's Sergei Karpov, Japan's Hayato Igurashi, Canada's Clark McDonald, Germany's Mratin Schormann, France's Grace Bellanger, and Italy's Marco Abiatti. This was foiled by the Animorphs. The Yeerks next attempted to infect California Governor Eleanor Watson. Watson's first husband Brandon Grant attempted to kill her in 1995, but she was saved by her Gene Watson( a member of the famous Watson family), who would become her second husband. Gene Watson fell under the control of a Yeerk but was freed by the Animorphs. Now being aware of the threat the Yeerks posed, Eleanor Watson didn't know who in the government could be trusted and so decided to go public. She would be seen as a hero for this. Several government agencies would have preferred the invasion to be kept secret as it meant their efforts to combat it would be kept secret and reduce panic but accepted the reality once the Yeerks were publicly revealed. Josiah Bartlett was contacted by Eleanor Watson and afterwards, both agreed to go public.

"I won't beat around the bush. I have declared a state of emergency. I repeat: a state of emergency. This is not martial law. Our police, and even our National Guard forces, cannot be trusted. The news media cannot be trusted. You may not even be able to trust your friends or your own family. I know this sounds fantastic. Like something out of Vinewood. But by now you've seen the alien invasions. You've seen the news footage. You know what I'm telling you is true. Our state, our nation, our entire world is under attack. But we are already fighting back. I have requested help from Washington, and the president has agreed to send U.S. troops."

### **Earth-Yeerk War(1999)**

One of the first acts of the Yeerks once war was declared was to destroy Bahia Bay, California, though anticipating this, most of the city was evacuated. The G8 members, learning their lives were nearly taken over, immediately joined together. U.N.I.T. and Stargate Command shared what information they had. Reports from Minister of Magic Kingsley Shacklebolt revealed that Dolores Umbridge, then in custody, attempted to negotiate her freedom in exchange for sharing information on the Yeerks but her request was denied and in fact never shared outside of the Ministry. Naturally the immediate concern was the invention of technology capable of determining a Yeerk Controller, which was soon developed with X Ray technology. A Major problem cam in the shift in leadership among the Yeerks. While Visser Three had preferred slow infiltration to bypass Earth defenses. The failure of this plan led to Visser One taking over, who believed that a direct invasion, which had so far worked on every other world, would work on Earth as well and so all subterfuge attempts ended. Visser One did not take into account that several alien invasions had recently transpired on Earth.

A Human Space Fleet led by the flagship, the Archangel Michael, which had defeated the Fithp invasion, battled the Yeerk fleet. The Fithp had sworn loyalty to Humanity after their defeat and now fought alongside them. A group of Superheroes wearing specialized suits such as Tony Stark and Captain Future fought in the fleet as well. this attack bought enough time for reinforcements to arrive, coupled with reinforcements from other planets. Jake Berenson, leader of the Animorphs, blew a hole in the Yeerk flagship blowing an estimated 150,000 Yeerks into space. The Yeerks were forced to surrender with Yeerk leader Visser One, also known as Esplin 9466 was captured and tried for war crimes. All Yeerks were forced to leave their home.

Races freed from the Yeerks settled on Earth such as The Hork-Bajir, which relocated to Jellystone national Park, and the Taxxons, which morphed into anacondas and were relocated to the Amazons. Both refugee races were targets for anti-human movements along with the Tectonese and the Prawns and were the targets for Senators such as Bob Roberts and Kevin Keeley. The Andalite protected these races and so no action was taken against them. In 2012, SCP-1000, Located in Jellystone was used to save the Hork-Bajir race when the volcanoes in the part erupted. Escafi Cube technology was shared by the Andalites as a form of hormone replacement therapy. There is only one survivor of the original Animorphs team which has chosen to remain anonymous.

The Yeerks found themselves once more reduced back to their own home planet. Isolated into the Yeerk Pools, deprived of their great technology and imprisoned. They made another effort at conquest centuries later but were thwarted by the crew of the Starship Enterprise D and were further conquered by the Borg, ending their hope of becoming a great power once again.
