List of minor Yeerks

This is a list of minor fictional Yeerks from the "Animorphs" series. In the "Animorphs" universe, Yeerk numbers are pronounced one at a time; Aftran 942 would be said "Aftran nine-four-two."

Aftran 942

Aftran 942 is a Yeerk, but unlike the majority of her species, she does not want to dominate other species. Her host was a young girl named Karen, When Cassie ran away from the Animorphs in "The Departure" (#19), she met a lost Aftran but didn't kill her because she didn't want to kill Karen.

Aftran tried to explain the Yeerks' plight to Cassie, who wound up making a deal with the alien. If Cassie would become a "nothlit", stuck permanently in the body of a caterpillar, Aftran would free Karen and would no longer infest any other human. Cassie agreed. Near the end of the two-hour morphing limit (the point of no return as far as morph went), Aftran told Cassie she could return to human form, but the caterpillar had no sense of hearing. (She later was able to morph back, as caterpillars "naturally morphed" into butterflies, which reset the morphing clock).

It is later revealed in "The Sickness" (#29) that Aftran is the leader of a movement called the Yeerk Peace Movement, all of whom do not wish to dominate their hosts. When Visser Three found out about this movement, Aftran was captured. Mr. Tidwell, the vice-principal of the school (one of Aftran's allies), tells the Animorphs. Because the other four Animorphs and Ax were disabled by an Andalite flu, Cassie went in there with Mr. Tidwell and managed to rescue her. Aftran later helps Cassie operate on Ax to remove an organ that would have killed him. Knowing that she was going to starve to death, Aftran asked Cassie to kill her; however, Cassie and the others agreed to give her the morphing power to become a "nothlit". She chose to become a humpback whale.

Akdor 1154

The yeerk who led the uprising against the andalites. Died on the Campaign for the Hork-Bajir.

Arklan

A gedd-controller. Severely wounded by shredder backfire during the Hork-Bajir Campaign.

Carger 7901

One of Visser Three's peers during the battle for the Hork-Bajir world who appeared in "The Hork-Bajir Chronicles". Started referring to himself as "sub-visser" and gave the order to have Seerow and his family incinerated, over Esplin's protests to wait for the fourth Andalite, Aldrea to appear. Esplin's advice was not heeded, but later proven the wiser, when Aldrea later became a leader of the Hork-Bajir resistance to the Yeerk invasion. Esplin considered him too aggressive and crude. Carger is killed when a Jubba-Jubba bites off his host's head.

Council of Thirteen

The Council of Thirteen is the top governing position of the Yeerk Empire, above all the Vissers in rank. The Council is rarely seen, but mentioned fairly often; Visser Three often discusses his dream of becoming a Councilor, as do Visser One and likely all the most prominent Yeerks. Their only appearance in the series is in the novel "Visser," chronicling Visser One's trial before the Council. Though she escaped their wrath on that occasion, it was short-lived, as they ordered her executed when she failed them on the Anati world.

The Council apparently existed before the Yeerk Empire; Visser Three mentions it had already been in place during the time of "The Hork-Bajir Chronicles." One of the Thirteen is Emperor, though only the Council knows who; the Emperor's identity is kept secret, so that no assassin, Yeerk or otherwise, could succeed in killing him without killing the entire Council. Also unknown is the Council's location (their "Visser" appearance was via hologram) or their ultimate fate, after more than half of their forces were defeated in the final battle for Earth.

Only one Councilor, Garoff 168 (see below), is identified by name. He, along with most of the Councilors, have Hork-Bajir hosts, while two have Taxxons. Two Councilors remain forever concealed in the shadows, making their forms unknown.

Eslin 359

Ax meets Eslin 359 in "The Alien" (#8), three weeks after the Animorphs destroyed the Kandrona machine in the previous book. The Yeerks had to keep going up to the mothership to receive a minimal amount of Kandrona to survive. However, there were too many Yeerks and not enough capacity, so many Yeerks died. Eslin lost his lover and was angry, sabotaging a feeding schedule as revenge. When he meets Ax, he gives him the location of Visser Three's next feeding ground in the hopes that Ax would exact vengeance. However, although Ax poisoned Visser Three, the Yeerk itself slipped out and Ax could not bring himself to kill a fellow Andalite warrior. Eslin sneered at this failed attempt but did not report Ax to his superiors. Ax met him one last time to relay a message to the Andalite home world. His human name is Gary Kozlar.

Esplin 9466 Lesser

Esplin 9466 Lesser is a Yeerk who appears in "The Warning" (#16). The double six at the end of his name signifies that he was formed from the same grub as another Yeerk, half of a pair of twins. However, his identical brother happens to be the same Yeerk who is Visser Three. In the case of twins, one gets all of the power and rewards, and in this case Visser Three had the power and gave his twin a low-ranking host.

However, Esplin 9466 Lesser turns his misfortune around. His host is Joe Bob Fenestre, and Esplin invented Web Access America (an analogue of America Online that, in the Animorphs universe, is the world's most popular Internet service provider) through his host, which was an easy task for superior Yeerk technology. It made Fenestre a billionaire. Joe Bob's Horatio Alger story, as he progressed from an ordinary telephone repairman to an Internet pioneer, has become famous enough by the time of the Animorphs story that Marco regards him as a hero.

He obtains vast knowledge of information by sifting e-mails and spying chat rooms. He was a great asset for the invasion. Visser Three, fearing his rising popularity and ambition, declared him a traitor, which forced Esplin 9466 Lesser into hiding. Fenestre builds a huge mansion and heavily guards it. Knowing that his twin's host has the ability to morph into animals of all sorts, he equipped his mansion with weapons, ranging from Rottweliers and guards with submachine guns to insecticides and bug zappers to electrical force fields. His guards have instructions to shoot anything that attempts to come close to the house. This poses a great difficulty to the Animorphs; when they attempt to pay him a visit, Rachel and Ax are captured and they are forced to retreat.

He explains to the Animorphs that the only reason why he is still alive today is due to his technique of survival. Cut off from Kandrona rays, he is now a cannibal. He captures fellow Controllers, splits the host's head open, and grinds the Yeerk into a powder that he then ingests. Visser Three keeps him alive only because he wants to learn that technique; but, as he explains, the technique would never catch on very well for the rest of the Yeerks.

After explaining this to the Animorphs, Cassie, horrified by his cold-blooded attitude towards humans and Yeerks, demands that Jake kills Esplin. Jake, however, had already agreed not to harm him, but adds a condition: Esplin may never leave his mansion again, or the Animorphs will find him and kill him. Esplin agrees. However, by the end of the book, his house burns down under mysterious circumstances; it is implied, but never stated, that Jake or Cassie may have done this. Nobody died in the fire, but Esplin's fate afterwards is never disclosed, including whether or not Jake fulfilled his pledge to kill him.

Esplin 9466 Lesser makes a minor appearance in the prequel, "The Hork-Bajir Chronicles", which chronicles the origin of Visser Three, appearing alongside his twin before the Yeerks are attacked by Aldrea's army.

Essak 241275

The Yeerk supposedly in Jake's head in the alternate future he visited in "The Familiar" (#41). He was a planetary engineer working on the project to convert Earth's moon into a Kandrona-radiating miniature sun, based in the Chrysler Building.

Essam 293

Essam 293 is a Yeerk engineer based on the Yeerk home world who appears in "Visser" in the form of flashbacks. He accompanies Edriss 562 (then Sub-Visser 409) on her mission to find Earth, and later falls in love with her. He infested a human named Hildy Gervais. In human hosts, they conceived twin children, Darwin and Madra. However, he later disagreed with Edriss' philiosophy and tried to defy her; Edriss cut off Kandrona rays. Essam died of Kandrona starvation.

Garoff 168

Garoff 168 is a member of the Council of Thirteen and Edriss 562's former mentor, whose sole appearance is in "Visser". He is the speaker at the trial of Edriss 562. During the trial, Edriss strongly suspects that he is the Emperor, and wonders if only his opinion matters. Garoff is sympathetic to Edriss and tries as much as possible to get her free. For instance, when it is clear that Edriss has committed treasonous acitivities, he decides to resume the testimony instead of convicting her. Edriss is stunned at first, but it is her host, Eva, that realizes that Garoff is trying to get her free. During a lunch break, Edriss calls up the Animorphs to make an appearance, which discredits Visser Three (he had earlier staged a battle against several wild animals which he claimed were the "Andalite Bandits" — his apparent defeat of them gained him the council's approval, temporarily).

Illim

Illim is the Yeerk who controls Mr. Tidwell, a teacher at the Animorphs' school. He appears in "The Sickness" (#29). He is a member of the Yeerks' Peace Movement and a friend of Aftran 942.

Iniss 226

The Yeerk in control of Hedrick Chapman, a very high-ranking Controller. Iniss 226 agreed to cooperate with its host, Hedrick Chapman, who desired above all else to protect his daughter Melissa.

The Inspector

The Inspector was sent to check up on Visser Three's progress on the invasion of Earth. His host is a Garatron, an alien similar to an Andalite, but one that moves much faster. However, he is bitten by Marco in cobra morph. Visser Three decides not to help him, because he knows the Inspector would have given him a bad review. The Inspector dies from the poison.

Janath 429

A very old, very wise Yeerk, and apparently one of some level of importance. He was present during the declaration of the Yeerk Empire and its plans to conquer the Hork-Bajir homeworld. Died during the Yeerk conquest of the Hork-Bajir.

Niss

In Book 41: "The Familiar" (narrated by Jake Berenson) Niss is the Yeerk who controls future Cassie. She is part of the Evolutionist Front (The EF) , a group of Yeerks who wished to create artificial symbiotes rather than taking natural, sentient hosts.

Odret 177

Odret 177 is the Yeerk who infests Tobias in "". The book is set in an alternate universe that chronicles what would happen had the Animorphs not received their powers. Tobias joins the Sharing and becomes a Controller: he almost willingly surrenders his freedom, but resists at the last minute. Odret is loyal to the current Visser One, Edriss 562, which leads to his execution by Visser Three.

Temrash 114

Temrash 114 is a Yeerk who infests both Jake (in "") and his older brother Tom. Temrash was originally waiting for a promotion (to infest the Governor) when the Animorphs invade the Yeerk pool. Jake accidentally falls in, and Temrash infests him to avoid death when Jake boils the Yeerk Pool.He first believed that he could fool the other Animorphs, but they soon realize that Jake is not acting normally, and tie Jake up for three days until Temrash dies. His death causes Jake to see Crayak, a recurring dream that haunts him until book , when the Animorphs confront Crayak.

Visser Two

Visser Two is the Yeerk controlling a human who orchestrates an attempt to start a World War 3 in "The Deception" (#46). His host is a lieutenant of the U.S.S. "George Washington". When something attacks the "George Washington", he arranges for a fake report to state that it was from a Chinese submarine. According to his plan, several hours later, the U.S. government will receive a report that the Chinese made an unprovoked attack, which would lead to a World War 3 and millions of lost lives. Only Visser Two had the authority to stop his men from shooting, so Ax morphs into his host and other various humans. Ax hijacks an F-14 Tomcat with a nuclear weapon and puts Visser Two in the cockpit with him. Ax calmly states that he will bomb the location of the Yeerk pool (having a single bomb that was loaded previously on the plane), killing thousands of Yeerks, in an attempt to convince Visser Two to call off the attack. Furious, Visser Two agrees, and his plan is defeated.

Visser Four

Visser Four is the Yeerk who infested John Berryman who appears in "Elfangor's Secret" (Megamorphs #3). He lost the rank of Visser Four after losing the campaign on Leera to the Andalites. In "", he discovered the Time Matrix and intended to use it to change history, in order to make the future invasion easier for the Yeerks. When Crayak and the Ellimist deemed him dangerous, they sent the Animorphs after him. They managed to finally stop him on D-Day on the beaches of Normandy. In the ensuing chaos, Marco throws him into a burning tank. With the Time Matrix, the Animorphs rewrote the past so that Berryman would never exist, and Visser Four would presumably have never infested him.
