Shion Uzuki KOS-MOS Ziggy :Voiced by (English):
Richard Epcar (Episodes II & III)Voiced by (Japanese):
Masashi Ebara As revealed in
Xenosaga: Pied Piper, which takes place in T.C. 4667, 100 years prior to the events of
Xenosaga Episode I, Jan Sauer was a Captain in the 1875th Special Operations detachment of the Federation Police Bureau. He and his squad were deployed to the planet Abraxas to investigate murders in the U.M.N network committed by an individual known as "Voyager". During their investigations, he met the widow Sharon Rozas, with whom he fell in love and later married, and her son Joaquin, and learned that Yuriev was providing funding for Voyager's murders. Soon after, Dimitri used his connections within the government to remove Sauer and his team from the investigation, but he continued his investigation even after he and some of his subordinates were arrested. Following the death of his subordinate Mikhail Ortmann, Sauer discovered that Erich Weber, a member of his team, was Voyager. Erich explained to him his connection with U-DO before he transformed into the Black Testament and killed Sharon and Joaquin before giving him an ultimatum: either he killed him and consumed his soul, or he joined him as a Testament to live forever. However, Sauer refused either option and committed suicide, being reactivated two years later as the cyborg Ziggurat 8. Though he is implied to understand some of the events surrounding the Zohar, his past is generally not explored, except for in
Xenosaga I+II, where he reveals more of his past to the party. In
Episode I, the S.O.C.E. sends him to infiltrate a U-TIC organization base and rescue M.O.M.O., who gives him the name Ziggy, and he becomes a father figure to her. After escaping on a spacecraft, the
Elsa saves them from being destroyed by the U.M.N. column walls and they meet with the party, with him joining as a support party member. In Cathedral Ship, when Cherenkov diffuses into the Zohar emulator and begins his transformation into a Gnosis, Ziggy states that it is "the same, just like that day.", as Voyager transformed into the Black Testament through the same method. Following the destruction of Proto Merkabah, he helps rescue KOS-MOS after Shion loses hold of her. In
Episode II, Ziggy continues to protect M.O.M.O., even beyond his assigned mission, and bonds with Juli Mizrahi after revealing to her that he committed suicide because of Joaquin's death, as the loss of their children caused painful memories for them. She also asks him to consider life extension, which he does for M.O.M.O.'s sake. However, despite her sympathy for him, most employees of the U.M.N. Control Center regard him as old property. Within Labyrinthos, he sacrifices his cybernetic arm by breaking through a wall to help the party escape from the Ω System. At the end of
Episode II, he is to be stationed at the Kukai Foundation and remain on call as a bodyguard for M.O.M.O.
M.O.M.O. :Voiced by (English):
Sherry Lynn (Episode I),
Christina Puccelli (Episodes II & III) Specifically, she is a prototype
100-series Observational Realian who Joachim Mizrahi and Juli Mizrahi created using genetic engineering to combat the Gnosis and resurrect U-DO. They created her in the likeness of their deceased daughter, Sakura, and with the appearance and personality of a twelve-year-old girl, and she does not show signs of aging. Despite being capable of thought and emotion, she and Juli had a strained relationship, as she saw her as a reminder of Sakura and nothing more than an artificial human. After Joachim's death, MOMO was rescued from her birthplace during the Miltian Conflict and sent to live with Juli on the planet Fifth Jerusalem, the hub of the Galaxy Federation. Among her Ether skills is the ability to transform into a more powerful version of herself through a transformation sequence. The costume she wears determines the ether-based abilities she can access for a duration. In
Episode III, she gains the ability to immobilize enemies by filling up their "Break meter". In
Episode I, S.O.C.E and Juli assign Ziggy to rescue MOMO from the U-TIC Organization and protect her until her safe return. Throughout the series, she is central to the story because she contains the Y-Data. This makes her the target of kidnappings by Albedo and U-TIC When Albedo attempts to extract the Y-Data from her body, which nearly kills her, she attempts to stop him by destroying her mind, but he obtains it after threatening Jr., after which she asks Juli for permission to assist in the investigation of Old Miltia. Following the events at Michtam, MOMO begins working with everyone to rebuild the world, believing that a new network will help to reunite those who have died.
chaos :Voiced by (English):
Joshua Seth (Episodes II & III)Voiced by (Japanese):
Hoshi Soichiro , also known as Yeshua, joined the crew of the
Elsa two years prior to the events of
Episode I, tasked with ensuring the safety of the crew during their travels and assisting in tasks such as in-flight functions and transporting cargo. chaos appears to be unaffected by physical aging, as he has the same physical appearance during the main story of
Xenosaga as well as during the time of the Miltian Conflict, when he served under the Galaxy Federation fourteen years ago, and in
Pied Piper, which takes place one hundred years earlier. 6,000 years ago, when he was known as Yeshua, he was one of the disciples of a man whom Ormus would come to worship as their Lord and Messiah and helped to teach humanity and perform miracles in his place. According to Wilheim and the database, chaos died physically during this time, leaving behind the "Word of Yeshua", also known as Lemegeton, with the Song of Nephilim being an incomplete translation of it. Lemegeton is a wavelength energy that is represented in the material world as words that can only be understood and spoken by chaos (Anima), and. when recited, allows them to access and control the Zohar and access energy from the Higher Domain of U-DO. Although humans are unable to speak these "words", ancient people and future researchers, such as Grimoire Verum, created programs from Lemegeton to control the Zohar. These programs were used in the Relics of God that harnessed the Zohar's energy, such as Zarathustra and Omega. People of the Zohar, whose wills resonated strongly with Anima due to their bloodline, could also control the Zohar, with the strongest being able to communicate with U-DO.
Episode III reveals that chaos is the human incarnation of Anima, a power derived from humanity's collective unconscious that has been present since the beginning of the universe, when certain wills of humanity resonated purely with Anima; according to the database, these were past incarnations of consciousnesses capable of becoming Testaments, including the party members. These wills set off a chain reaction throughout the collective consciousness, resulting in the dispersal of consciousnesses that rejected the collective consciousness and became Gnosis in the real world. Eventually, the dispersal of the collective consciousness would cause the universe to collapse. To counter this, Anima possessed a failsafe function that would cause the imaginary number domain to collapse if the Gnosis exceeded critical mass, which in turn would cause the collapse of the universe as well as the real number domain and the upper domain. To save chaos' life and prevent destruction, Mary used her power of Animus to seal away the power of Anima into the twelve Anima Vessels by separating his soul into the Anima power, which was divided into the twelve Anima Vessels, and the Will of Anima, which is the failsafe. When separated from his Anima power, chaos' failsafe ability could not activate. However, as long as Anima existed, the consciousnesses would continue to disperse. To prevent this and the destruction of wills, Wilhelm chose
eternal recurrence, using Zarathustra to rewind time in an eternal cycle that caused people to live the same lives repeatedly. At the end of
Episode III, chaos rejects the eternal recurrence and trusts the wills of humanity to change the future. Realizing that his power can be used to save the universe with the help of human wills who wish for it, he instructs Shion and her friends to lead humanity back to Lost Jerusalem, which holds the key to saving the universe. After the awakened KOS-MOS restores his power, chaos believes that he will disappear after releasing his power to slow the destruction of the universe and give humanity more time to find Lost Jerusalem. However, his consciousness lives on, as the consciousnesses of the universe desire his existence. After saving the
Elsa by holding open an U.M.N. gate to allow them to escape the shockwave of the dimensional shift, he is last seen speaking to KOS-MOS as she drifts through space.
Gaignun Kukai Jr. (Rubedo) :Voiced by (English):
Brianne Siddall (Episodes II & III)Voiced by (Japanese): Eriko Kawasaki U.R.T.V. #666 and the leader of the U.R.T.V.'s, Jr., also known as Rubedo, was a survivor of the U.R.T.V. (U-DO Retro Virus) unit that the scientist Dr. Yuriev created to combat U-DO, a mysterious waveform that threatened to destroy the galaxy. He and his twin brother, Albedo, U.R.T.V. #667, were born conjoined twins, with Albedo being attached to him through the heart until they were separated; Gaignun Kukai was the last brother, known as Nigredo. He possesses the unique abilities of the U.R.T.V.'s, including telepathy and telekinetic powers, and is said to have the perfect anti-U-DO wavelength, which is generated when in his "Red Dragon" mode. Along with Albedo, Nigredo, and Citrine, Jr. is one of the "variants," U.R.T.V.'s who undergo a stimulated mutation, which caused his hair to turn bright red and his eyes to turn deep blue. It also gave him the ability to pause his cellular development and the power of the "Red Dragon" mode, which allows him to amplify the anti-U-DO waves emitted by himself and Standard U.R.T.V.'s, increasing his power but also risking causing him to go berserk. He has a tattoo of a red Chinese dragon on his left upper arm, which symbolizes this mode; as a result of subconsciously suppressing it, his aging is also suppressed. Despite his youthful appearance and impulsiveness, his maturity allows him to make tough decisions and cutting observations. He also has a fondness for guns, action movies, and classic novels, such as
The Adventures of Robinson Crusoe,
The Wonderful Wizard of Oz, and
Twenty Thousand Leagues Under the Seas. Because of his hobbies, Jr. is a master of gunplay, especially with pistols, and enjoys fighting akimbo. He wields dual Rook Company pistols at the beginning of
Episode I, and dual antique Makalov pistols in
Episode II. During the Miltian Conflict, Jr. and the other U.R.T.V.'s fought against U-DO before the planet disappeared into the Abyss. As leader of the U.R.T.V.'s, Jr. was responsible for keeping them connected through a spiritual link that protected them from U-DO's destructive powers. Before the U.R.T.V.'s could destroy U-DO, Jr. had a vision of the Old Miltian planet being destroyed as a monster emerged from within. Jr., fearing for the lives of his companions, broke the Spiritual Link, allowing U-DO to kill or drive mad the standard U.R.T.V.'s before Canaan and chaos rescued Jr. and Nigredo on the E.S. Asher. They were the only documented surviving U.R.T.V.'s, though Albedo and Citrine also survived. Over the course of
Episode I and Episode II, Jr. and M.O.M.O. bond due to Jr.'s past with Sakura Mizrahi, whom MOMO was modeled after, as when they were children, he promised Sakura that he would protect her mother and "little sister". In
Episode III, Jr. comes to terms with issues surrounding the remains of his "family"; his brothers Albedo and Gaignun, his sister Citrine and his father Yuriev. After the party confronts Dr. Sellers on the Tactical Warship Merkabah, he reveals that Yuriev is alive due to inhabiting the body of his "son", Nigredo. The party heads to the
Durandal to confront Yuriev, where they discover that its crew, except for Mary and Shelly Godwin and the cruisers' guests, Juli Mizrahi and Canaan, were murdered by Yuriev soldiers, and are confronted by U.R.T.V. #668, Citrine. Jr. tries to convince Citrine that what she and Yuriev are doing is wrong, but her dedication to her father's ideals has caused her to be willing to fight her own "brother" and die if need be, and dies after being defeated by the party. In the Isolation Area, Jr. confronts Yuriev as he removes the Zohar Emulators from their containment units and reveals his plan to conquer his fear of God (U-DO) by ascending to the realm of the gods and killing him. Before the party can stop him, the
Durandal's engines activate and it leaves on a collision course with Abel's Ark as Yuriev disappears into the inner recesses of Isolation Area and the party flees before the ship is absorbed by the Ark. In Abel's Ark, Jr. defeats Yuriev and Ω Res Novae/Ω Metempyschosis when Albedo, as the White Testament, arrives and takes the Zohar and Abel away from Yuriev before confronting Jr. While he orders Jr. to link with him and use their anti-U-DO waves to destroy Yuriev, Gaignun's consciousness emerges from Yuriev's and tells Jr. that it was Albedo's plan to transfer Gaignun's consciousness into Jr.'s body, but Gaignun instead took over Albedo's body and transferred Albedo's consciousness into Jr. Gaignun shifts himself and Yuriev into a higher dimension and Jr. and Albedo merge back into a single person. From there, he follows the party to Michtam to stop Zarathustra and Wilhelm and accompanies Shion and Allen to find Lost Jerusalem. Jr.'s adult form was meant to appear in
Episode II. In the original script written by
Soraya Saga, partway through the game Jr. would unpause his growth and age to adulthood. His adult self would be a playable character and be part of several key sequences in the later sections of the game, such as a reunion with U.R.T.V. #668 Citrine and a three-way battle between KOS-MOS, U-DO, and him and Albedo. While cut from the script, the concept was reused in
Episode III as a representation of Jr.'s true self.

Michael Gough (Episodes II & III)Voiced by (Japanese):
Hideyuki Tanaka Shion's brother, who, during the Miltian Conflict, stole information from Margulis about the true nature of the Miltian Conflict—the Y-Data. After joining chaos and Canaan in their search for the U.R.T.V.s, Margulis challenged Jin to a duel which ended in him receiving a gash over his right eye that left a permanent scar. While in the military, he was ranked under Margulis and was Pellegri's superior. Both Jin and Margulis trained under his grandfather, the swordmaster Ouga Uzuki, who also taught Shion martial arts abilities. After learning of Margulis' treachery during the Miltian Conflict, Jin received information from his father Suou and secret intelligence activities under General Helmer, who was then a lieutenant, and became acquainted with chaos. While he was close to Pellegri during his time in the military, they took different paths in life due to differences in their relative stations. At the end of

Canaan :Voiced by (English):
Beng Spies (Episode II);
Steve Blum (Episode III)Voiced by (Japanese):
Hiroshi Kamiya is a special Realian created by Vector Industries, who, like M.O.M.O., can pilot an E.S., specifically E.S. Asher. He is not designed like the other Realians and is referred to as an "Enhanced Memory Model" by M.O.M.O. when they first meet in Helmer's office. During the Miltian Conflict, Lieutenant General Helmer sent him and chaos on a mission to retrieve the U.R.T.V.s and the Y-Data, during which the U-TIC Organization activated the Song of Nephilim, which nearly affected Canaan and caused Federation Soldiers in A.M.W.S. to attack him and chaos. Jin Uzuki saved them and led them to U.R.T.V.s location at Labyrinthos, headquarters of U-TIC. After he and Margulis fought, he entrusted Canaan with information regarding the Miltian Conflict, which is also a fragment of the Y-Data, but something happened that made this data inaccessible to him. Some time later, they found and rescued the variant U.R.T.V.s Jr. and Nigredo (Gaignun Kukai). Fourteen years later, Canaan is still unable to read the data and experiences occasional blackouts accompanied by data loss, and has spent time at Vector's 2nd Division on Second Militia attempting to extract the Y-Data from his head. Representative Helmer asks him to save Jr., chaos, Ziggy, and M.O.M.O. from being attacked by U-TIC A.W.M.S. Units and he joins the party as they return to Old Milita to extract and analyze the data. After being antagonised by Doctus throughout the first half of
Episode III, Canaan realizes his true identity after analyzing data corresponding to 'Program Canaan' and that he had been a spy for Wilhelm. In
Episode III, the special characteristics of Program Canaan allow Canaan to secure a bypass route to Wilhelm's power and convinces him that he could die after his power as a Testament fades and connects Voyager's consciousness with the Compass of Order and Chaos. He and Voyager are then sent into
phase space, destroying their bodies. Canaan is a playable character in the first dungeon of
Episode III and wields an energy knife.
