[This is my translation of the 5,000 word Japanese Wikipedia article on Maetel's mother. My own comments, which are kept to a minimum, are enclosed in brackets .La Andromeda Promethium (ラー·アンドロメダ·プロメシューム) is a fictional character appearing in the works of Leiji Matsumoto.
1. Voice Actresses
· Ryoko Kinomiya (Galaxy Express 999 TV series, two 999 movies, others)
In the Comments section of the Roman Album for the Adieu Galaxy Express 999 film, Kinomiya had the following to say on Promethium: “Wasn’t she really a kind mother?”
· Keiko Han (Millennial Queen, Maetel Legend, Space Symphony Maetel: Galaxy Express 999 Side Story)
In the TV version of Millennial Queen, the credits show her role as Yayoi Yukino and Yayoi/Millennial Queen. Han has commented on the Promethium of Legend and Space Symphony at the round-table performers’ interview included in the special features of the Space Symphony Maetel DVD (see below).
2. Character Outline
She appears in the 999 story as Queen Promethium, supreme ruler of the Mechanization Empire. In addition to being Maetel mother, she is the founder of the Mechanization Empire and former spouse of Doctor Ban. She calls herself “ruler of the universe” and her burning ambition is to extend eternal life throughout the entire universe by means of the “mechanization of bodies”.
From 2000 on, the new OVAs Maetel Legend and Space Symphony Maetel were released. These were considered the missing link designed to plug in the gap between 999 and Millennial Queen. It became clear that Yayoi Yukino from Millennial Queen and Promethium from 999 were the same person. As a result, Promethium’s full name must be Yayoi’s LaMetalian name as it was revealed in Millennial Queen. Also, it is now clear that Millennial Queen is the story of Promethium’s youth.
Maetel Legend describes how Promethium returned to LaMetal and eventually transformed into the queen of the Mechanization Empire, but the particulars of the tale differ greatly from the way this is described in the second 999 film.
She is a fanatical believer in machines and in the words of her former husband Ban “a pitiful machine woman”. At the same time, she bears an extraordinary affection for her daughter Maetel (see below). However, she is merciless toward whoever gets in her way, and she will not forgive even her own daughter and husband when they do. According to Maetel’s speech in the 999 TV version, in former times “she was as kind a mother as Tetsuro’s”. But “once she began to aim for the realization of eternal life through mechanical bodies, Mother changed.” In the show itself Promethium already lacks that warm, human heart.
During her youth, Promethium lived the life of a hard-working person, always loyal in adversity. In the original 999 there is a scene where she appears before Tetsuro and talks about the life journey she has led (this scene is repeated in the second movie, this time before Maetel).
She despises all flesh and blood humans except for Maetel. In the original 999, for example, she swore at Tetsuro when he showed up , calling him a “foolish flesh and blood biped.” She often uses the expression “foolish humans” as well.
She is considered a great entity by the mechanized. The mechanized soldiers that battle Tetsuro in the opening scene of Adieu 999 are seen chanting Promethium’s name. In addition, after the control center of the Galaxy Express has fallen under the power of Promethium’s associate Black Knight Faust, a massive relief patterned after her face is set up therein. However, for those flesh and blood humans who believe in the beauty of a limited existence and the struggle against the mechanized forces, she is a menace and a being that must be overthrown.
4. Form · Distinctive Features of her Appearance
Her face in the first 999 film resembles a woman’s Noh mask with completely black eyes and a gear design on her brow. The TV version and the original comics follow this basic pattern. Furthermore, her portrait from the time that she was still a flesh and blood human, shown inside the old castle on the planet LaMetal in Adieu 999, reveals a similar face to her post-mechanization one.
Judging from Promethium’s appearance in the OVAs post-2000, it is thought that Maetel has inherited her mother’s looks from her human period (especially the hair color and her facial features). Emeraldas, who beginning in the works of the 1990s was set up as Maetel’s sister, resembles Promethium’s younger sister Selen (older sister in the Millennial Queen TV version) in her character, conduct and sense of justice .
Promethium’s appearance changes somewhat in each work. Following is a record of her post-mechanization form in each of the shows.
4.1. Galaxy Express 999
4.1.1. First film (Galaxy Express 999)
Her first appearance. She bears a mechanized humanoid body with a face resembling a Noh mask. Her hair blends into a black robe on which is reflected outer space.
4.1.2. Second film (Adieu Galaxy Express 999)
In the second film, the great mother planet Dai Andromeda that Promethium built is also her body. She exists as a white body of energy residing in the core of the planet, and when that energy explodes her face can be seen floating within. The setting is a large audience room surrounded by a transparent elliptical barrier, which also appears in the original work.
There is a separate control room for the regulation of the planet’s energy output. Maetel came here to operate on the computer terminal in an attempt to end Promethium’s life, but failed. The room contains several pipes with a white flame rising through them, and for a single moment during Maetel’s operation the flames all vanished. Upon reappearing, the ghostly face of Promethium could be seen within each pipe.
Yoshinori Kanada, a very popular animator at the time, was in charge of the design. The cels have the smoothness usually associated with CG animation.
4.1.3. TV version
She appears as a mechanized humanoid with blue hair. She wears a black cloak with sleeves reaching past her hands. Compared to her appearance in Adieu 999 and in the original work, this is her most human-like form. Her eyes are human-like as well, with a black part and a white part.
4.1.4. Original work
She resides in the core of the planet Dai Andromeda, resembling, in the words of Tetsuro, a “severed machine head”. As the words imply, she is the head of the Mechanization Empire. Behind her face is another one similar to Maetel’s (like Janus of Roman mythology), and she shares a personality with the latter. During the third film Eternal Fantasy there is a flashback revealing Promethium in this form.
4.2. Maetel Legend
In this sequel to Millennial Queen, she first appears wearing a black dress and a red diadem. However, during the course of the action machines gradually multiply and take over her body. By the end, she has achieved total mechanization with a face as white as a Noh mask and a body reflecting outer space.
This form is very similar to the design in the first film, except that here the cloak’s color is blue and she seems to be somewhat younger.
4.3. Space Symphony Maetel
When Maetel is in the process of destroying and escaping the planet, Promethium appears before her in the same black dress and red diadem of Millennial Queen, but now instead of a heart-shaped gem there is a mark in the shape of a cogwheel. In addition, the hair color has changed from blond to green, and her eyes are completely black. She possesses a powerful regenerative ability, and when she is cut by Maetel and Emeraldas’ gravity sabers, outer space can be seen through the wounds.
Even though she revives after being defeated by her daughters, from that point on she shows herself to Maetel and others in the form of a holographic Noh mask-like face.
5. Record of deeds
In the chronological order of the metaverse the sequence is Millennial Queen → Maetel Legend → Space Symphony → 999. However, the works were released in this order: 999 → Millennial Queen → Maetel Legend → Space Symphony. There is no thorough continuity between these different works.
5.1. Millennial Queen
She appears as the Millennial Queen, the ruler of Earth from the planet LaMetal, which approaches Earth once every thousand years. She goes by the name of Yayoi Yukino on Earth and secretly presides over the Earthlings’ dealings.
For more information please refer to the Millennial Queen article [in Japanese!!!].
According to the original webcomic released by Matsumoto on Tsuburaya Pictures’ official Maetel Legend site (now closed), Promethium talks of her life on Earth as Yayoi Yukino from 1001 to 2001. Because of this, the two OVAs Legend and Space Symphony may be considered as sequels to the Millennial Queen comic story.
5.2. Maetel Legend
After her return home to LaMetal she becomes Queen, marries a man by the name of Doctor Ban and bears twin daughters: Maetel and Emeraldas. In order to save the LaMetalian citizenry from the cooling of the planet due to its abandoning of the Solar System, she resolves to change to a mechanical body capable of withstanding the new and cruel environment. She undergoes an operation under the guidance of the mechanized doctor Hardgear, in which a capsule is inserted to accelerate the mechanization process from the forehead throough to the brain. However, she begins to suffer sharp pains and her whole body commences mechanization. Hardgear’s goal was to mechanize all LaMetalians and bring the planet under his rule. Even as her body is being consumed by the machines Promethium sends a distress signal to the Galaxy Express 999, the only way out for her daughters . Once these have been sent on their way, she herself completes mechanization. She then goes on to defeat Hardgear, who was scheming to drain her power by assimilating her to himself, and replaces him as the instigator of the mechanization of LaMetal and the extermination of all humans. From now on she is a machine queen.
5.3. Space Symphony Maetel: Galaxy Express 999 Side Story
Several years after Legend, the mechanization of LaMetal and its humans has progressed under Promethium. Maetel returns home after having received a letter from her mother. Promethium appears before her daughter in the form that she had prior to mechanization, and asks her to become the next queen. In reality her true self has merged with the planet’s central machine, and what talks to Maetel is but one of several clones stored in the interior of the planet for the purpose of impersonating and protecting Promethium. Promethium dispatches clones with different personalities (kind, cruel) depending on the circumstances and persons to be dealt with. Emeraldas also meets one of these clones from Promethium.
The abrupt pace of mechanization provokes a reaction from the citizenry. Promethium’s subordinate Leopard and his men, while ostensibly obedient to the queen, support the rebel cause and direct the LaMetalian fleet to attack the capital. Maetel, who seems about to succeed her mother, has in fact returned home in order to overthrow the mechanized queen. Following instructions from the former queen LaRela, Maetel manages to detach the planet’s core and destroy LaMetal.
Promethium’s true self is in the midst of escaping the collapsing planet when she is confronted by her two daughters and forced to fight. She overpowers them with her great regenerative ability. However, Maetel’s blood is infused with a strong desire “to overthrow Mother” and as some of the blood seeps into Promethium’s body, it destroys the mechanical cells and causes the body to crumble away like sand. Still alive, she uses space dust and other materials to rebuild her body. After that, she dispatches a fleet of mechanized men to attack the new planet born of the detached core of LaMetal. This fleet is rebuffed by Leopard and Harlock, but during the struggle Promethium constructs a new artificial planet bearing her name.
The self-reparative function of planet Promethium is so powerful that it allows Promethium to trifle with Harlock’s Death Shadow and the Queen Emeraldas. At one point the gigantic laser cannon at the planet’s center is fired at the Death Shadow, but the blow is warded off by the shield of the vessel Nazca, piloted by Maetel. The cannon breaks down, overloaded from the high intensity of the energy emitted. During the several hour-long repair, the planet’s defensive system employs anti-spacecraft firepower to stave off attacks.
Maetel and the others initiate a withdrawal, but based on a hint from Tochiro, they decide to turn back and destroy the new planet from the inside. Maetel transforms Nazca, a boy she met on the Galaxy Express 999, into the screw necessary for the destruction of the planet. Using his ship, she penetrates the planet. Promethium dispatches many androids to Maetel, attempting to induce her daughter to reach the planet’s center and insert the screw carrying Nazca’s will. She mistakenly believes that this component will support the planet whereas in fact, once integrated, it begins to effect its destruction. The screw with Nazca’s will opens up an escape route for Maetel to leave the interior of planet Promethium, which she manages to do successfully. Harlock and the others, waiting for Maetel, attack planet Promethium. The planet begins to collapse and after a great explosion it is totally destroyed, along with the queen.
But not all is destroyed. A core part of Promethium remains and awaits the chance to reconstitute itself.
5.4. Galaxy Express 999
5.4.1. Film version
126.96.36.199. First film
This is her very first appearance, preceeding even that in the original work. As for subordinates, in this film we find her mechanized Imperial Guard and the medical team in charge of operating on Tetsuro to transform him into the “living screw” that will support her planet’s essential machinery. One can also see two female attendants that look normal except for the eyes. However, there is no close associate or trusted retainer as in the later works.
Maetel has a pendant around the neck which is Ban in disguise, and which contains a capsule with the power to tear the Mechanization Mother Planet / Planet Maetel apart. Maetel hesitates to throw it at the heart of Planet Maetel but Tetsuro steps in to do just that. The planet is destroyed and for a moment it seems that Promethium will share its fate, but she manages to follow the escaping Tetsuro and Maetel all the way inside the 999 and tries to strangle Tetsuro to death before Maetel’s eyes. However, the 999 waitress Claire sacrifices herself to protect him and both she and and Promethium are destroyed. Immediately after her death, flames erupt from the surface of Planet Maetel and the planet ceases to existence with one great explosion. While she is trying to strangle Tetsuro, Promethium says to Maetel: “You’ve robbed me of everything”, but technically it was only half (details below). It is for this reason that the word “everything” here is thought to indicate “everything of mine on the Planet Maetel”.
188.8.131.52. Second film
The sequel Adieu Galaxy Express 999 features Tetsuro’s father, the Black Knight Faust, as Promethium’s subordinate. In order to expand Mechanization, Promethium sends mechanized soldiers to Earth, the first of all planets with flesh and blood humans. She intends to exterminate the population. However, so much energy has been stored near Dai Andromeda that the Dark Comet Siren Witch, which wanders throughout the universe in search of peculiar energy, is drawn to it. The planet is swallowed by the Witch and is annihilated. In this sequel the past history of Promethium and Maetel is revealed. Their old homeland was the planet LaMetal; together they built a palace there in which they lived. Promethium herself relates the events that occurred between the time she sent Maetel off on a spaceship (as LaMetal was drifting away) and the founding of the Mechanization Empire. The following facts come to light: the planet Dai Andromeda was created before the planet Maetel of the first film; just as Maetel was split into a human form and a planet form, so Promethium was split the same way. When Promethium meets Maetel again, she remarks “We have both lost half of ourselves” (because in the first film both Maetel’s planet form and Promethium’s own human form were destroyed).
5.4.2. TV Version
In the TV animation, Promethium has a mechanized subordinate called Mirai, with a body of glass like Claire’s. Her palace resembles a tower in the shape of a demon’s face.
Her silhouette and voice appear in episode 108 (Macaroni Gratin Collapse). The ending credits have her name as プロメシュウム. She is not in the manga chapter of the same name. In the TV episode, Promethium urges her daughter Maetel to bring Tetsuro quickly, as the two are nearing the final station. Macaroni Gratin Planet is controlled by an artificial brain named Mother Computer Jr. (Mothercom Jr.) which orbits it. The Dendrobium Brothers were plotting to escape Macaroni Gratin by taking the place of Tetsuro and Maetel aboard the 999, and Promethium has Mothercom Jr. deal with them as a result. At this time Maetel addresses Promethium as “Dear Mother”. Tetsuro is confused by the statement.
Afterwards, the 999 arrives safely at Terminal Station Planet Promethium. Maetel calls on her mother at her palace. There she is handed the pendant that lodges her husband’s soul. The pendant predicts that Promethium’s heart will be pierced by Tetsuro’s Cosmo Dragoon. She tosses the pendant in a rage but Maetel manages to recover it and head to the undeground power reactor. On the way, Promethium projects a 3D image of herself in front of Maetel, forces her to relinquish the pendant and has her minions seize it and lock Maetel in a cell. As Tetsuro has rejected mechanization, the decision is made to execute him. Promethium’s men bind him up with the intention of putting him on the 999 and sending both into a black hole to be destroyed. The plan fails, however, and Tetsuro is able to ride the 999 back to planet Promethium and link up with Maetel, who has escaped the cell. In the meantime, Mirai has had a change of heart and she steals the pendant to return it to Maetel. Promethium ambushes Maetel and Tetsuro on the way to the power reactor. As the mother and daughter struggle, the pendant falls from Maetel’s hand. Tetsuro uses his Cosmo Dragoon to shoot the pendant, which hurtles toward the center of the reactor. The resulting pillars of flames engulf Promethium and she dies. Although the Cosmo Dragoon did not directly pierce Promethium’s heart, the fact that Tochiro’s pulling the trigger was the ultimate cause of her death proved the prediction right. Promethium’s palace sinks beneath cracks on the surface, and the entire planet bearing her name is sucked into a black hole and annihilated.
5.4.3. Original work
Claire’s mother is her subordinate, a woman by the name of Meno. In order to prevent flesh and blood humans on their way to becoming mechanized from having any preconceptions, she bears a perfectly flat and smooth face with a totally black body.
Because she possesses in her back an offshoot of Maetel’s self, Promethium is supposed to know all of her daughter’s circumstances and actions as she rides along with Tetsuro. According to Maetel, however, her mother has shut her heart and is unable to understand that she is intending to betray her in the end. Maetel throws the pendant containing the soul of Promethium’s former husband Ban into Promethium’s central area. In addition, Meno observes Tetsuro’s concerns for the fragments of her daughter Claire and realizes “I’ve made a mistake”. She betrays Promethium by halting Tetsuro’s transformation into the “living screw” that will support the planet. She also takes the replacement screw that Maetel kept in her lipstick and inserts it into the “Crucible” system which backs up the “Fire of Life”, a vital source of energy for the Mechanization Empire. Tetsuro shoots the nail with his Cosmo Dragoon, causing the Crucible’s pressure valve to open. The energy loss results in Promethium’s being instantly mommified, the balance of the planet Dai Andromeda being lost, and the star itself being dragged into the very center of the Andromeda Nebula, the so-called “Super-Gravity Grave from which not even light escapes” . Finally the existence, said by Meno to be immortal, of Promethium vanishes, along with the Maetel in her back. “History’s greatest and most powerful space empire”, the Mechanization Empire, swiftly crumbles away.
The following post-mechanization abilities have been noted.
6.1. Transformation of humans into screws
She transforms flesh and blood humans into “living screws”, which are components that support her planet. Tetsuro suffers the process in the original 999 comic. When this takes place, a wind blows from an unknown location, and lightning strikes the flesh and blood body, thus transforiming it into a screw. Promethium employs this ability on the youths brought to her by Maetel. Due to her associate Meno’s betrayal, however, Tetsuro averts this destiny.
6.2. Holographic projection
Seen in the 999 TV version and in Space Symphony. Using this ability, Promethium appears before Maetel and shows her scenes from LaMetal as they talk.
6.3. Rewriting of soul rings
“Soul ring” refers to the soul data possessed by human beings. Promethium has the ability to extract the data and rewrite it. In other words, the ability allows her to rewrite the nucleus upon which a person’s mind and character are formed. She can control the subject’s mind and eliminate any rebellious tendencies. In Space Symphony, besides using it on her own clone bodies, it is revealed that she stole half of Maetel’s self when they embraced at the time of Maetel’s departure from LaMetal, subsequently using the data to create a legion of androids. At the end of this story Promethium awaits her chance for revival, foreseeing that she will be able to return to her former self through the use of this ability.
7. Expressions of feeling toward her daughters
In the original 999 work as well as in the second film, Promethium dies while shouting out to Maetel, revealing through this display of human affection that even after mechanization there still survive in her maternal feelings for her daughter. In the TV version she never wavers in her resolve to kill Maetel once she has opposed her goals. When Tetsuro points his gun at her, she uses Maetel’s body for a shield. In addition, the first film has Promethium strangle Tetsuro before Maetel’s eyes in retaliation for her beloved daughter’s betrayal. Here Promethium seems to enjoy Maetel’s distressed crying. Putting this scene together with those mentioned earlier once can conclude that Promethium is portrayed as having a conflicted love-hate relationship toward her daughters. In the comic, she recalls that the young Maetel loved how spiderwebs covered in dew glittered in the morning, and reveals that she has lighted up the streets of Dai Andromeda to resemble this phenomenon. This is evidence of a great deal of affection directed toward her daughter. In Space Symphony Maetel, Promethium shows an extraordinary level of attachment toward her daughter. She creates a great number of androids similar to her dutiful attendants in the the first 999 film and addresses each of them as “Maetel”. In the end, however, she is unable to produce anyone that she can replace the true object of her affection.
Regarding her other daughter, Emeraldas, we can conclude from Promethium’s statement in the first 999 film, where she calls Maetel her “beloved only daughter”, that she has erased her from her memory. On the other hand, when in the same film when the Queen Emeraldas ship attacks Planet Maetel (ruled by Queen Promethium) a faint smile can be seen playing on her lips. That said, at the time of the first film there was no record to the effect that Emeraldas was Promethium’s daughter (see below).
8. Changes in the Story
Throughout the Galaxy Express 999 story there is no mention of any other names for her aside from Promethium. Subsequent to the revelation in Millennial Queen (at that time running in Sankei Shinbun) that heroine Yayoi Yukino’s LaMetalian name was La Andromeda Promethium, Matsumoto himself declared that Millennial Queen was in fact the story of Maetel’s mother, Promethium. At this point the connection Yayoi Yukino = 999‘s Promethium became clear. However, when the story was made into a film the question “Is the Millennial Queen Maetel?” was fixed as its catchphrase, and Matsumoto himself made statements to the effect that Yayoi was Maetel . The standard interpretation became that Yayoi Yukino from Millennial Queen and 999‘s Promethium were separate individuals, and moreover Maetel and Emeraldas were rivals and not sisters, as seen in the 999 Andromeda series . However years later in the second part of the Ring of the Nibelungs, named Valkyrie and published in the 1990s, Maetel and Emeraldas are seen together during childhood and are said to be sisters. There is also a scene in the third part, Sigfried, where Maetel refers to her mother as La Andromeda Promethium. Furthermore, in the Maetel Legend OVA Promethium appears as Yayoi = Promethium, mother of Maetel and Emeraldas. The transformation into the Queen of the Mechanization Empire is portrayed therein.
Han, who took up the role of Promethium’s voice again after many years in Legend, had this to say in connection with the story changes: “I myself lead the life of a mother, so I tried to join my experience to Promethium’s troubles as a ‘mother raising children’.” Concerning the portrayal in Legend and Space Symphony of Promethium’s transformation into the Queen of mechanized worlds, Han commented in her Space Symphony DVD Special Features interview that “while I thought it was necessary to change my performance along with the process of her transformation from a flesh and blood human to a mechanized being, I wanted to allow for some corner of Promethium to preserve that flesh and blood identity.” She added that she “wanted to play the human Yayoi Yukino again”, from which one can conclude that Han harbored some regrets or wishes regarding her performance as the heroine in Millennial Queen, Yayoi Yukino.
9. Concerning her name
As was stated earlier, her formal name includes “the Second”. This means she is the second Promethium, and the relationship with Maetel can be seen therein [I don't see it!]. However, when her formal LaMetalian name was introduced in the original Millennial Queen comic, it did not have the “II” attached to it. It began to be used later when Matsumoto was stating that “Yayoi = Maetel” and the film’s aforementioned catchphrase was being employed. Moreover, it seems likely that “Promethium” is meant as a title for the queens of the Mechanization Empire and the supreme authorities of LaMetal. Evidence for this can be found in the Adieu film, when a rumor begins to spread that Maetel has succeeded her mother as Queen. The partisan combatant Meowdar, who is battling the Mechanized troops on Promethium’s old home of LaMetal, claims that Maetel is being hailed as the new Promethium.
The source of the name “Promethium” is the element of the same name. According to Matsumoto, this metal can only exist within a nuclear reactor and is thus an extremely artificial element . As to why she is named Promethium, the opening to Legend states that the Andromeda Sun contains the heavy metal promethium which does not occur in the natural world. Now, the name of the element is derived from the god Prometheus of Greek myth. Acording to one legend, Prometheus created humans that looked exactly like the gods and taught them the use of fire. Promethium herself created a Mechanized Civilization, endeavoring to spread eternal life through mechanized bodies throughout the entire universe. As such, in the world of the 999 stories, Promethium can be seen as a character with cultural hero status.

11. Sources and footnotes
1. In the character introduction for Promethium on page 132 of Takarajimasha’s “Complete Edition Galaxy Express 999 PERFECT BOOK”, her name appears spelled as “Promesium”.
2. In an info book published while Millennial Queen was being serialized, Selen is introduced together with Emeraldas in the character relationships diagrams, etc.
3. At this time Promethium tells her daughters that “before the planet LaMetal strayed from its thousand year orbit, the 999′s route was already in operation.” However, in the Millennial Queen timeline LaMetal breaks away from the Solar System around 1999 (in the TV and film versions) or 2001 (original version), but in that era the Galaxy Express did not travel to Earth. As mentioned earlier, this creates difficulties for establishing a continuity.
4. The credits show him as “Maetel’s Father”; he is never called “Doctor Ban” within the actual work.
5. The Eternal Fantasy series agree with the TV version in calling it a “black hole”.
6. This is according to Matsumoto’s remarks in Sankei Shuppan’s (now known as Fusosha Publishing) “Film Edition New Bamboo Cutter Tale Millennial Queen” part 4, page 124.
7. Remark from the special radio show on the day prior to the release of the Millennial Queen film. This can also be confirmed from the “Millennial Queen Quiz” promoted by Toei Films’ Publicity Dept. before the film came out; by Matsumoto’s Q & A in the May 1982 issue of Tokuma Shoten’s “My Anime” (after the film’s release); and by No. 52 of the “Roman Album” released to accompany the film Arcadia of My Youth (Tokuma Shoten, 1982). That said, the pamphlet that came with the Millennial Queen film includes a character relationships diagram that shows Maetel and Yayoi as sisters.
