Eureka (エウレカ, Eureka) is a member of the Gekkostate.

Eureka is a girl born by the Scub Coral, a race of assimilating, intelligent, lifeforms that landed on Earth via falling satellite. She has pale skin, medium length aquamarine hair, and medium violet-red eyes. She wears a one piece dress that is blue and white. Also, she is the pilot of the Nirvash typeZERO Light Finding Operation. Eureka treats the typeZERO not like a machine, but as a companion or an intelligent being.

A bit of an enigma, Eureka is a lovely young girl who rarely shows emotion; she rarely smiles and never laughs. Eureka mostly speaks very calmly and directly never hesitating to speak her mind. She is often perplexed by other peoples emotions and behaviors. She understands machines better than humans, is more than an expert LFO pilot and used to be part of a Military Special Operations Force Unit untill she left with Holland. However, her physical and mental states undergo many changes after meeting Renton Thurston.

HistoryEdit

MangaEdit

Manga BackgroundEdit

Eureka was found in a mine along with the Nirvash typeZERO's archetype by Adroc Thurston, who believed her to be a gift from God. Adroc tried to release the Nirvash's Powers in a controlled manner along with Eureka but failed, thus causing the epidemic, the Summer of Love. However he was able to stop the effects, thus gaining the title of a hero. After Dewey had Adroc killed, Eureka was placed under the care of his younger brother, Holland. They were both assigned to the the SOF (Special Operations Force). During this time Eureka grew to trust Holland to a degree equivalent to her trust of Nirvash, but she was still emotionally dispatched and unaware of her sense of self. Then one day, the SOF was given a mission to eliminate all the people living at Ciudades del Cielo, under the belief of bringing the murderers of Adroc to justice. Eureka killed many people but she finds three children still living in the pile of corpses she just killed. Realizing that she was killing people, she decides to protect the kids. When Holland learns that it was not the Voderac but Dewey who killed Adroc, Eureka leaves the SOF with him, stealing the typeZERO and the Gekko Ship.

Awakening Nirvash

In episode 2-Blue Sky Fish, after Renton Thurston delivers the Amita Drive during a high pace action scene of the activation of the Seven Swell. Eureka explains to Renton to trust in her and his feelings which began the awaking of the The Type Zero's power,causing what is called the seven swell affect.

AnimeEdit

Anime BackgroundEdit

Eureka was found in a mine along with the Nirvash typeZERO's architype and she was immediately brought to Tresor Laboratories for study. It was found that while the typeZERO would not work well with any human at the controls, it responded well to Eureka being the pilot. Soon after that she met Adroc Thurston, who taught Eureka how to speak and interact with others. His influence on Eureka was that of a father. After Adroc's dissapearance in the New Era Summer of Love, then the Lieutenant-Colonel Dewey Novak had Eureka placed under the care of his younger brother, Holland. They were both assigned to the the SOF (Special Operations Force). During this time Eureka grew to trust Holland to a degree equivalent to her trust of Nirvash, but she was still emotionally detached and unaware of her sense of self. Then one day, the SOF was given a mission to eliminate all the people living at Ciudades del Cielo. Eureka kills many people but when she finds three children still living in the pile of corpses she just killed. Awakening to her sense of self for the first time, she decides to protect them. Taking them in the Nirvash, she rendezvous with Holland who was talking to Master Norb of the Voderac. Later, she joins Holland in a revolt against the United Federation, aiding in stealing the Gekko, an experimental ship, and has since been on the run with him.

Retrieving the Amita DriveEdit

Upon orders from Holland, Eureka travels to Bellforest in Nirvash to retrieve the Amita Drive under the guise of having Nirvash repaired. She crashes into and destroys the room of Renton Thurston, who falls in love with her on first sight. The next morning Eureka asks Renton if she could borrow the flamethrower in the back. She explains that she feels bad about destroying Renton's room and feels that she must make it up to him. While talking with him she reveals that she doesn't need a Compac Drive to operate the Nirvash as others do, Renton decides to lend her his Compac Drive and inserts it into its place saying that he's a professional mechanic who knows that machines have feelings too. Eureka surprises him by saying that that was common sense. She then leaves to borrow the flamethrower. She uses the flamethrower on the remains of Renton's room in order to give it a funeral, much to Renton's dismay. She smiles upon seeing Renton having his shoes burned trying to put the fire out and then mourning them.

Back in the Nirvash, the Compac Drive doesn't work so Eureka tells Renton to take it off since she never needed it before and cannot believe in stuff she doesn't understand. She goes on to say that just believing in something doesn't mean it something will necessarily come of it, sometimes believe leads to great misfortune and other times it is hard to believe in anything at all. Renton tries to argue against this but Axel Thurston interrupts by voicing his realization that Eureka is one of Holland's friends. Then he produces a strange device saying that he knows that this is what Eureka is after. He goes on to tell her that his family was torn to pieces because of this thing, so she can take it but never return. Suddenly Eureka senses missiles flying towards them and tells both Thurstons to hang on. She pilots the Nirvash out of it's restrains and away from the garage before it is destroyed. Nirvash transforms into vehicle mode and the Thurstons are flung off in the process. Unable to stay any longer she pilots the Nirvash into leaving by gaining speed and then transforming into Robot Mode and utilizing the Ref Board. She then engages the oncoming KLFs in combat.

Holland and Matheu soon try to join her in combat against the KLFs. But they are kept apart. She tries to lose the KLFs to no avail and is suddenly interrupted by Renton's arrival on his Ref Board. Unfortunately Nirvash's slipstream causes Renton to lose his balance and fall so Eureka saves him by navigating the Nirvash under him and catching him. Upon opening her eyes after closing the hatch she finds Renton clinging to her and telling her about his pulling off a cutback drop turn and his confessions of love for her. She doesn't understand. Renton pulls out the Amita Drive, explains about it to Eureka and then and plugs it in. The result is that Nirvash deactivates and Eureka falls unconscious for a few moments. Renton tries to pilot the Nirvash but it doesn't respond until Eureka regains consciousness just enough to put her arms around him and tell him that he can believe in her. Suddenly the Amita Drive activates and the Seventh Swell effect is activated. Renton defeats all the KLFs and falls unconscious. Holland comes to recover Eureka and Nirvash, he then comments of the power of the Amita Drive. But Eureka tells him that the source of the power was Renton. She then takes Renton back to the Garage.

Upon seeing Renton smiling while sleeping Eureka asks Axel why Renton is smiling and voices her opinion that what Renton did was reckless. Axel tells her that that may be but he will still complement Renton because he is "family". Eureka repeats the word questioningly and Axel tells her that she will understand when she becomes a mother. Eureka starts to say something but is interrupted by the arrival of Holland. Eureka witnesses Axel and Holland get into an argument and notices that Renton is awake as well. After Holland talks to Renton, Eureka asks Renton to come with them.

TransformationsEdit

Eureka's Original FormEdit

This is Eureka's starting form. In this form Eureka looks just like a normal teenage girl with the exception of her hair, which is Aquamarine in color, and her eyes, which are Medium Violet-Red. However she is initially cold and distant as a result of her being unaware of much of what humans take for granted, like smiling, love, etc.

Manga TransformationsEdit

After being Attacked by Anemone and theENDEdit

Eureka underwent a transformation after she and the Nirvash suffered damage from theEND. Mentally, she stopped trusting; and physically, her skin started being covered with slime and huge scabs that hindered her movement.

After Watching Renton WoundedEdit

When Renton was badly wounded protecting Eureka from the new SOF Squad sent to gather Eureka's Bio Data and eliminate her, Eureka's love for Renton came back and she tore off the scabs holding her. The Result was that mentally, Eureka learned that love hurts but also can give joy; while physically, Eureka gained scars all over her body.

Anime TransformationsEdit

After being Absorbed by the CoralEdit

After Renton saved Eureka from the Coral absorbing her, she is found to be covered in a cocoon like substance which is fused with her skin. Mischa was unable to remove the substance without harming Eureka so Holland decides to accept a mission to save a Vodarac High Priest. Once saved the High Priest performs a Guidance Ritual to release her. Free of the Cocoon, Eureka emerges scarred, with short light blue messy hair and lacking eyebrows. She bears this form untill meeting Sakuya.

After Meeting SakuyaEdit

Before leaving Sakuya's Heart, Eureka is offered to have her scars fixed but she refuses saying that these scars are the outward proof of what she has been through. Sakuya responds by commending Eureka's strong will. Upon emerging Eureka is shown to have regained her former appearance. Her hair is now loose without the clips holding them back and her scars have become less prevalent.

After Reaching the Promised LandEdit

Upon passing the Great Wall, via the Void, and reaching Earth, known as the Genuine Promised Land, Eureka undergoes her most intense transformation yet. First her left arm starts getting covered by green swellings. Afraid of what the others might think, she initially tries to hide them and then run away but the others soon find her and the secret is revealed. When Renton bashes his arm in an attempt to become like Eureka she understands that Renton would not turn away from her and reconnects with him. However Renton's injury gets infected and he develops a high fever as a result. While caring for a sick Renton, Eureka sheds a tear and her left arm completely morphs into corralian form, furthermore winglike appendages grow out of her back. Eureka is once more afraid of what Renton might think when he wakes up, but upon seeing her Renton is entranced and comments on how beautiful Eureka has become, much to her joy.

Eureka's Final FormEdit

When Dewey dies, the collar on Eureka begins affecting Eureka's physiology and her skin morphs completely into Coralian green before she is enveloped in a sphere of black and red energy. When Renton and the Nirvash Spec3 force their way into the sphere, Renton encounters Eureka whose arm has turned back to normal but is still having her green wings. He ties her hair back with a hair clip revealing a small green gemlike spot in the middle of her forehead.

RelationshipsEdit

Renton ThurstonEdit

Renton Thurston, also known as the boy, is the so-called chosen one and the soul mate of Eureka. He is also the protagonist in the story. Renton and Eureka's relationship is complex throughout the story. Started out as Renton having a big crush on a beautiful girl that crashed into his grandpa Axel Thurston's garage, Renton begins to understand how his role affects Eureka and that of the Nirvash TypeZERO. Because of this, Eureka begins to reciprocate Renton's feelings for her. It was because of Renton's love for Eureka and, later, Eureka's deep love for Renton that many of the impossibles happen like going to the promised land which is Earth, and saving the world from the Coralian exceeding the limit of life. Eureka never formally marries Renton, but the record book Axel Thurston wrote that Eureka was Renton's wife, and the kiss in Episode 50 with the lake scene allows viewers to presume Eureka and Renton are eventually formally married.

Maurice, Mater, and LinckEdit

Rescued children from a city named Ciudades del Cielo during the time when Eureka and Holland were still in the United Federation of Predgio Towers Special Forces which was renamed to as the Gekkostate when Holland decided to bail out of the military. Prior to Renton teaching Eureka how to discipline the children and being the male role model to the children, the kids were snotty and bratty. They tease and cause lots of trouble to the Gekkostate, especially Renton Thurston. Despite that, they love Eureka very much, even reffering to her as "Mama" and are very protective of her. Especially Maurice who was willing to kill Renton because he thought Renton was responsible for Eureka's transformation.

Holland NovakEdit

Eureka joined Holland Novak's special squad when she was found next to the Nirvash TypeZERO and seeing that she was the perfect pilot for the Nirvash. Holland always thought as being the partner of Eureka, but Norb states that Eureka will have a partner other than Holland and Dewey. It is the boy that makes her truly smile from the heart, that will become her partner. Still, Holland protects Eureka from harm and did not accept that Renton was her partner till the first half of Season 2.

ThurstonsEdit

Ever since Eureka was found, Axel Thurston was a part in building new technologies for the Nirvash TypeZERO. Adroc Thurston assists Eureka till his mysterious disappearance which was later found out that he was with the Scub Corals. There isn't much evidence whether or not Diane (Renton's sister) was seen with Eureka. It seems as though Eureka didn't know about Diane till Renton introduce Diane to Eureka.

GekkostateEdit

Eureka has a special status in the Gekkostate, being one of the original members and how Holland Novak took care of her. She was also seen in the Gekkostate as being a mother to the adopted Maurice, Maeter, and Linck. After Renton's recruitment, she changed little by little. By Season 2, Eureka was seen with Renton more often than the first season.

Ao FukaiEdit

Ao Fukai is Eureka's biological son and the main protagonist in the second series. Ending up on Iwato Jima while giving birth to her son, with only Toshio Fuka knowing her true identity, Eureka concealed her herself from the other residents of the island by dying her turquoise hair brown. However, the residents of Iwato Jima handed her over to the American military ten years ago prior to the second series in the aftermath of the last Scub Burst to hit the island. By fate, getting flashbacks of his mother while he was little, Ao became the pilot of the IFO Nirvash while adapting some of his mother's physical features.
