Shiki Granbell
Shiki Granbell (シキ・グランベル) is the sole human denizen of Granbell, a robot-inhabited theme park planet. Shiki uses the Ether Gear "Satan Gravity" (サタングラビティ) to freely manipulate gravity for himself and others, a power learned from his surrogate grandfather, Ziggy, who found the infant Shiki on a voyage for Mother beyond the Sakura Cosmos. He is characterized by his obsession with making friends, as well as a paralyzing fear of bugs. After Granbell's dying robot community chases him away with Rebecca to save him from solitude on their planet, Shiki searches for Mother to fulfill his goal of making 100 new friends across the universe. In the process, he receives the Edens Zero from Elsie Crimson and inherits Ziggy's title of "Demon King" as the ship's captain. Eventually, Shiki discovers his origins as the sole survivor of a dying planet Earth, Mother's original form 20,000 years in the past, who was brought into the present era after the Chronophage briefly returned Mother to her planetary state.

Continuing his theme of naming protagonists after seasons, Mashima chose the Japanese word meaning "four seasons" (四季) for the main character of Edens Zero to represent the culmination of his previous works. The series' second half features the character's transition into a young man, which was planned early in development. Mashima hesitated to incorporate the change due to concerns of negative reactions from "fans of the boyishly cute Shiki"; he left traces of his old design to alleviate this, describing the change as "shifting him from cute to cool". Shiki is voiced by Takuma Terashima in Japanese, and by Sean Chiplock in English.

Rebecca Bluegarden
Rebecca Bluegarden (レベッカ・ブルーガーデン) is a B-Cuber and Shooting Starlight member from the planet Blue Garden, where she lives after being separated from her parents, Connor and Rachel, during her childhood. She aspires to attain one million subscribers for her B-Cube account, Aoneko Channel (AONEKOチャネル), which suffers from low viewership due to poor-quality content. She is an expert markswoman who acquired her skills from playing first-person shooter video games. After stimulating her Ether through repeated baths in the Edens Zero's spa, Rebecca develops her own Ether Gear called "Cat Leaper" (キャットリーパー), which enhances her jumping power and agility, and allows her to rewind time and mentally "leap" into parallel universes at different points in time. This power becomes the source of Etherion, which is extracted from a version of her who is killed and sent 20,000 years into the future by a spacetime distortion on the planet Nero 66.

Mashima named the character after the Japanese band Rebecca, drawing inspiration from their song "Friends" to compliment Shiki's friend-obsessed personality. Rebecca is voiced by Mikako Komatsu in Japanese, and by Kira Buckland in English.

Happy
Happy (ハッピー) is Rebecca's best friend and partner, based on the character of the same name from Fairy Tail. He is a feline alien from the planet Excede who was fatally injured in a traffic accident during Rebecca's childhood, leading their benefactor, Professor Weisz, to transfer Happy's mind into an identical android body to help him survive. Happy can transform into a pair of firearms called Happy Blasters (ハッピーブラスター), which fire non-lethal Ether bullets. He loses his mechanical abilities in Universe Zero, where he never experiences his accident and remains flesh and blood. Rie Kugimiya and Tia Ballard reprise their roles from Fairy Tail as the Japanese and English voices for Happy, respectively.

Weisz Steiner
Weisz Steiner (ワイズ・シュタイナー) is a man from the planet Norma who practices the Ether Gear "Machina Maker" (マキナ・メイカー), which allows him to instantly remodel machines to improve their performance, deconstruct them, and create weapons. As a result of Weisz fleeing Norma before the Chronophage rewinds fifty years of its history, there are two alternate versions of him that co-exist as separate people: his adolescent self, an amoral but good-natured criminal who joins the crew after betraying his gang; and his elderly, present-day self, who has since matured into an esteemed robotics professor. During the crew's travels, the young Weisz assumes a superhero identity named Arsenal (アーセナル), using a powered exoskeleton that he customizes with his Machina Maker.

Mashima described Weisz as "one of the good guys, but still a scumbag", which he noted is an uncommon character type among his works. He also said that Weisz's role in the story was "pretty clearly laid out", which made it "fairly easy to get [him] to do what I want". Weisz is voiced by Hiromichi Tezuka in Japanese; in English, his younger self is voiced by Ray Chase, and his older self is voiced by Brook Chalmers.

E.M. Pino
E.M. Pino (EMピーノ) is a miniature "anti-bot" android who generates an electromagnetic pulse (EMP) that disables machinery and Ether Gear within range for short periods of time. Pino was built by Ziggy to become the "Light of Edens" (エデンズの光), the "next generation" of androids to the Four Shining Stars, but had her memory erased by Weisz's gang when she arrived on Norma for maintenance from the present-day Weisz. She joins Shiki after assigning him as her new master, later desiring to be reborn as a human through Mother. During the crew's battle with Ziggy on Lendard, he restores some of Pino's memory while struggling against the Edens One's control, which allows her to fulfill her purpose of freeing him through her ability to Overdrive. Her full memory is left intact in Universe Zero, revealing that her intended role is to destroy the One.

Mashima created Pino to serve as the mascot character of the series, but during development of the manga, he found it increasingly difficult to include her within the first chapter, where he incorporated Happy to stand in for her. As with Weisz, Mashima said that he found it "fairly easy" to write for Pino due to her established role in the story. He later called Pino his favorite character in the series, adding that he worked out "a lot" of story details for her, and that she would "probably" become an important character. Her name comes from Mashima's attempt to make the term "EMP" sound "cute". Pino is voiced by Shiori Izawa in Japanese, and by Sarah Anne Williams in English.

Homura Kôgetsu
Homura Kôgetsu (ホムラ・コウゲツ) is a young swordswoman from Oedo, a planet styled after Edo period Japan. She is trained by Valkyrie Yuna to use the Ether Gear "Soul Blade" (ソウルブレイド), which creates swords and bladed weapons made of solid Ether. Homura has the habit of voicing her inner thoughts by mistake, stemming from Valkyrie's encouragement for Homura to overcome her quiet nature as a child. She first joins the crew to search for Valkyrie, who had gone missing for five years, and whom she regards as a mother figure after being abandoned ten years earlier by her uncaring biological mother, Kurenai. After discovering Valkyrie's death on Sun Jewel, Homura takes her place in the Four Shining Stars as "Valkyrie Homura". In Universe Zero's renewed history, she leads a miserable life in debt to Drakken Joe after witnessing Valkyrie's decapitation over Homura's accidental injuring of Seiji Hôjô, the son of Oedo's shogun, but recovers upon learning of Valkyrie's survival and reconciling with the now loving Kurenai.

Mashima chose the character's name, which means "flame" (炎), to give an impression of the color red and fire. Homura is voiced by Shiki Aoki in Japanese, and by Laura Stahl in English.

Four Shining Stars
The Demon King's Four Shining Stars (魔王四煌星) are a group of female androids created by Ziggy to serve aboard the Edens Zero. Its members possess functions and powers that improve the ship's travel capacity, with all four required to authorize the use of Etherion. Each android also possesses a Battle Dress (バトルドレス) that enhances her combat skills. In the final arc, the four are revealed to have been modeled after deceased humans from Earth who aided in the planet's transformation into Mother, and were given false memories as Ziggy's companions to function as Shiki's caretakers.

Witch Regret
Witch Regret (ウィッチ・リグレット) is the "Shield of Edens" (エデンズの盾), a masked sorceress who protects and manages the Edens Zero. She is modeled after Shiki's biological mother, a defense attorney from New York City. She manipulates her own Ether in a fashion similar to magic, using Shield Ether (シールドエーテル) to generate force fields, and Element Ether (属性エーテル) to perform elemental attacks such as ice, air, and lightning. She is portrayed as kind and gentle, yet ruthless towards those who threaten her crewmates. She is killed during the Aoi War, with Universe 2's version of her perishing with the rest of the crew against Shura's antimatter bombs, while Universe 3's version sacrifices herself to shield the Edens Zero from the explosion. Her death is eventually undone when the crew travels to Universe Zero's past, although she does not regain her memories of previous worlds due to her absence from the ship during Etherion's activation. Witch is voiced by Kiyono Yasuno in Japanese, and by Laura Post in English.

Sister Ivry
Sister Ivry (シスター・イヴリィ) is a dominatrix nun who serves as the ship's medic, the "Life of Edens" (エデンズの命). She uses a healing ability called "Heal Atomizer" (ヒールアトマイザー), which allows her to instantly treat wounds, cure afflictions, and repair "living" machines such as herself and other androids. She is described as "scary" and "foul-mouthed", and uses the masculine pronoun ore in Japanese. Sister is seemingly introduced as the leader of Rogue Out (ローグアウト), a mercenary squad on the planet Guilst, but is later revealed to have been impersonated for ten years by their leader, who held her hostage to monopolize her healing powers. In Universe Zero, her imposter's absence on Guilst leads to the real Sister forming Rogue Out as a vigilante corps that opposes Drakken Joe.

When talking about Sister's full name, Mashima said that it had no particular meaning, choosing it because he "liked the sound of it". Sister is voiced by Yukiyo Fujii in Japanese, and by Allegra Clark in English.

Hermit Mio
Hermit Mio (ハーミット・ミオ) is a programmer android with the appearance and behavior of a young tsundere girl, modeled after a schoolgirl from Japan. As the "Mind of Edens" (エデンズの心), she uses the hacking ability "Master Code" (マスターコード) to manage the ship's computer security and reprogram networked technology to her liking. When first introduced, Hermit suffers from mental trauma due to being cruelly exploited and experimented upon fifteen years earlier by the human Müller and his research team, leading her to isolate her mind within the virtual planet Digitalis. She initially rejects Shiki's friendship out of hatred for humans, but overcomes her mistrust after the crew's kindness rekindles her desire for human friends. In Universe Zero, she avoids her traumatic experience altogether due to Müller's absence, and is found spending time playing on Digitalis.

Mashima originally named the character "Hermit Milon" (ハーミット・ミロン) in her profile, but changed it after realizing he had already used the name for another character in the manga. He derived the name "Mio" from the Japanese word miotsukushi (澪標), which is used in waka as a pun on the phrase mi o tsukushi (身を尽くし), something that Mashima felt reflected her personality. When redesigning the character for the three-year time skip, Mashima changed Hermit's hairstyle due to her resemblance to Hatsune Miku, which he stated was not intentional. Hermit is voiced by Kanon Takao in Japanese, and by Xanthe Huynh in English.

Valkyrie Yuna
Valkyrie Yuna (ヴァルキリー・ユナ) is the "Sword of Edens" (エデンズの剣), the manager of the Edens Zero's armaments. She is also Homura's childhood guardian and "Soul Blade" mentor, and was modeled after an American surfer and physicist. Valkyrie is first mentioned as having been missing for five years, leading Homura to join the Edens Zero crew in search of her. On Sun Jewel, Valkyrie is revealed to have been dead for three years after perishing against a horde of monsters unleashed by Kurenai, Homura's mother, whom Valkyrie freed from slavery in a misguided effort to reunite Homura with her biological family. In Homura's revised childhood in Universe Zero, Valkyrie is decapitated for her student's injuring of Seiji Hôjô, but survives because of her android nature. She waits on Sun Jewel together with Kurenai for Homura, who aimlessly searches for her mother after mistaking Valkyrie for dead, allowing Valkyrie to reunite with her student and crewmates.

Mashima chose the character's full name because he wanted her to be "a darker-skinned character with a classically Japanese name". Valkyrie is voiced by Miyuki Sawashiro in Japanese, and by Rebeka Thomas in English.

Mosco Versa-0
Mosco Versa-0 (モスコ＝ヴェルサー零) is a white-colored sumo android who works aboard the Edens Zero as its caretaker and Sister's verbally and physically abused servant. He specializes in tsuppari techniques, which allow him to achieve flight. He also has a button on his belly that Sister forbids anyone from pressing, as doing so transforms him into his alter ego, a handsome butler named Cosmo (コスモ) who exerts total dominance over Sister. Debuting as a member of Rogue Out who is reprogrammed to follow Sister's imposter, Mosco resumes his original duties after the real Sister restores him. He returns to being a Rogue Out member in Universe Zero's revised history, this time under the real Sister as a vigilante with dozens of identical robotic copies.

Mashima did not originally plan to include Mosco in the Edens Zero crew, making the decision after he "took a liking" to the character while drawing him. The author based Mosco's name on the character's predetermined catchphrase, "Moscoy" (モスコイ), which comes from the sumo term dosukoi. Mosco is voiced by Mitsuo Iwata in Japanese, and by Brock Powell in English.

Jinn
Jinn (ジン), truly named Kris Rutherford (クリス・ラザフォード), is an O-Tech ninja who first appears as part of the mercenary squad Rogue Out, and later as a minion of Drakken Joe. He uses the Ether Gear "Wind Rage" (ウィンドレイジ) to perform ninjutsu techniques that produce winds with typhoon-like force. During his childhood, Jinn is made into a cyborg by Müller, who orphaned and dismembered him in front of his younger sister, Kleene, as revenge against their parents for withdrawing their financial support. Jinn seeks Sister out to cure Kleene's trauma from the incident, which allows Rogue Out's leader to deceive him by impersonating Sister until he kills the imposter upon her exposure. He boards the Edens Zero after gaining the real Sister's cooperation, remaining distant from the crew until Sister successfully treats Kleene. In Universe Zero's altered history, Jinn willingly becomes an O-Tech as part of his home planet's culture, but is forced into Drakken's service with Kleene after coming to Guilst by mistake while studying abroad.

The code name "Jinn" is taken from the wind spirit of the same name. Mashima gave the character "a lot more hair" to make him easier to draw during the series' second half, citing difficulties of drawing him consistently in the first half. Jinn is voiced by Yūki Shin in Japanese, and by Jonah Scott in English.

Kleene Rutherford
Kleene Rutherford (クリーネ・ラザフォード) is Jinn's younger sister, introduced as Sylph (シルフ), the Element 4's representative of wind. Her "Wind Snatch" (ウィンドスナッチ) Ether Gear creates air currents that are capable of stealing objects, redirecting projectiles, and trapping people in wind cages. She suffers from mental breakdowns whenever she experiences any emotion, caused by a repressed memory of Müller forcing her to watch Jinn's dismemberment during their childhood, which requires her to wear emotion-suppressing devices on her head that also indicate her mood. She joins the crew with Jinn after Sister cures her condition by erasing her traumatic memories. She avoids her traumatic experience in Universe Zero due to Müller's absence, although she becomes Drakken's minion anyway along with Jinn after coming to Guilst by mistake. Kleene is voiced by Rumi Okubo in Japanese.

Laguna Husert
Laguna Husert (ラグナ・ヒューゼルト) is a cross-dressing man who uses the water-manipulation Ether Gear "Tears Lover" (ティアーズラバー), which he combines with Empire Ether to transform others into water whenever they cry. Originally a stage actor, he suffers from an inability to cry naturally due to his over-commitment to his roles, which has led to his retirement. He first appears as the Element 4's representative of water under Drakken Joe, but is inducted into the Edens Zero crew by Witch after proving himself to be among Drakken's more humane minions. He is later revealed to be an estranged member of Oasis (オアシス), a rebel faction opposing Poseidon Nero that he deserted in pursuit of greater power to avenge his best friend, who was killed in a raid conducted by Nero's empire. In Universe Zero, Laguna is instead Oasis's leader. Laguna is voiced by Taku Yashiro in Japanese.

Couchpo
Couchpo (カウチポ) is a famous B-Cube personality and gourmand who produces food videos and reviews for her account, MoguMogu Channel (モグモグch.); her real name is Chloé Françoise Ai (クロエ・フランソワーズ・愛). First meeting Rebecca when they and several other B-Cubers are abducted by Rogue Out, Couchpo joins the crew during another encounter on the planet Foresta after being enamored with the ship's kitchen, and provides critiques that help bolster Rebecca's popularity. After traveling to Universe Zero, she uses her online influence to assist in luring the Chronophage to restore Mother to her original form as Earth. Couchpo is voiced by Satomi Arai in Japanese, and by Janice Kawaye in English.

Connor
Captain Connor (キャプテン・コナー) is a spaceship captain from the Aoi Cosmos. He appears as a pompous and eccentric middle-aged man with expert piloting skills, using unorthodox methods to push ships beyond their usual capabilities. As the story transitions through different universes, the crew meets alternate versions of Connor that only Rebecca remembers: the original Connor from Universe 1 is the Edens Ones shipwrecked captain whom the Zero crew rescues en route to Sun Jewel; in Universe 2, he is a reluctant servant of Ziggy who is hired as the Ones pilot; and in Universe 3, he is an escaped worker from Ziggy's robot factory on Lendard who has no knowledge of the One. He is eventually confirmed to be Rebecca's father, whose wife, Rachel, left him with their newborn daughter to protect him from being killed by her church for their forbidden marriage, with Universe 3's Connor joining the Zero crew and reuniting with his family after discovering his relationship with Rebecca. In Universe Zero, he declines returning to the crew to remain with Rachel on planet Miltz.

The character's design underwent multiple changes during development, all depicting him as thinner and more attractive than the finished version as an overweight old man, with different hairstyles varying from a receding hairline to "silky smooth" hair. After storyboarding Connor's debut appearance, Mashima received input from his editor that Connor's feats were "not very interesting" for a "good-looking" character to perform. According to Mashima, the final design received complaints from his female staff over the change. Connor is voiced by Kenta Sasa in Japanese, and by Paul St. Peter in English.

Labilia Christy
Labilia Christy (ラビリア・クリスティ), whose name is derived from the word "lovely", is a Shooting Starlight member and highly popular B-Cuber in the Sakura Cosmos. Depicted as a former friend to Rebecca, whose videos inspired Labilia to become a content creator as a means of coping with a terminal illness, she bullies Rebecca and produces videos mocking her content out of disdain for her lack of talent. In Universe 3, three years after her channel loses its popularity, she reconciles with Rebecca and is taken aboard the Edens Zero to be treated for her illness. She subsequently travels back in time with the crew to Universe Zero, where she uses her online influence to help them lure the Chronophage to restore Mother to her original form as Earth. Labilia is voiced by Ayumi Ayano in Japanese, and by Lizzie Freeman in English.

Edens One / Void
The Edens One (エデンズ ワン) is a more advanced successor to the Edens Zero, which serves as its prototype. Initially helmed by Connor, it is destroyed prior to the Zero crew's voyage to Sun Jewel in Universe 1, but is undamaged in all subsequent universes. The ship is commanded by Ziggy after his resurrection, with the ship's crew becoming the primary antagonistic group faced by the Zero crew as they seek the extinction of humanity. Following Ziggy's destruction, he is revealed to have been controlled by the Edens One itself, which possesses the time-displaced consciousness of Shiki and Rebecca's son from Ziggy's timeline, making the ship artificially intelligent and the true main antagonist of the series. In Universe Zero, the son inhabits an android body named Ōbā Nyū Ēterion Voido (ONE・ヴォイド), allowing him to access his parents' respective "Satan Gravity" and "Cat Leaper" abilities, and giving him a human appearance similar to Shiki.

Four Dark Stars
The Demon King's Four Dark Stars (魔王四黒星) are a group of four male androids built by the Edens One on Ziggy's behalf as successors to the Four Shining Stars. Like the Shining Stars, the Dark Stars are modeled after humans from Earth and acquaintances of their respective counterparts.


 * Wizādo (ウィザード), Witch's counterpart, is a magician who performs magic-like Ether attacks. His human model, Leonard (レナード), is the judicial colleague and husband of Witch's model, Regret, as well as Shiki's biological father. Wizard is voiced by Taishi Murata in Japanese.
 * Kuraun (クラウン), Sister's counterpart, is an effeminate clown who afflicts others with traumatic nightmares. His human model, Cooper (クーパー), is a surgeon who treated Sister's model, Ivry. Clown is voiced by Junichi Yanagita in Japanese.
 * Burigandain (ブリガンダイン), Valkyrie's counterpart, is a warrior with nearly indestructible armor. His human model, Howard (ハワード), is a surfer friend of Valkyrie's model, Yuna. Brigandine is voiced by Shōta Yamamoto in Japanese.
 * Kirā (キラー), Hermit's counterpart, is an assassin and programmer who creates holographic dimensions. His unnamed human model is the senpai of Hermit's model, Mio. Killer is voiced by Aoi Ichikawa in Japanese.

Müller
Müller (ミュラー) is a human mad scientist introduced as Hermit's primary abuser who manipulates her into destroying the robot planet Hook, an event leading to his arrest. He appears in the series' present as an O-Tech employed by the Edens One crew after losing his original body in a botched prison escape, perfecting his cybernetic body through torturous experiments he conducts on Jinn and Kleene during their childhood. After Weisz destroys his body, Müller is restored to human form in Universe Zero, where he is the head of Poseidon Shura's imperial science department. He fuses with a robotic duplicate of Xenolith to become one of the Oración Seis Galáctica, but fails to utilize Xenolith's gravity powers and is destroyed again by Shiki. Müller is voiced by Yōhei Tadano in Japanese, and by John Snyder in English.

Drakken Joe
Drakken Joe (ドラッケン・ジョー) is a loan shark who controls the Sakura Cosmos's criminal underworld, introduced as one of the Oración Seis Galáctica. He is nicknamed the "Dark Alchemist" (闇の錬金術師) for his Ether Gear, "Alchemist" (アルケミスト), which transmutes anything into different materials and forms of matter. Raised as a test subject with a fifteen-year life expectancy, Drakken sustains his youth for over 200 years with a life-support machine that steals countless people's life force, but also deteriorates his physical health. He targets the Edens Zero to extract Rebecca's Ether Gear for himself, viewing her mental time travel ability as a more efficient means of immortality. Following an encounter with Drakken that results in Shiki's death in Universe 1, Rebecca escapes to the parallel Universe 2, where the crew is able to reverse his life-support system, aging him into a feeble old man. In Universe Zero's altered history, Drakken sustains himself on the life energy of animals instead of people, forming a stronger moral code in the process. The character is named after the video game Drakkhen. Drakken is voiced by Taiten Kusunoki in Japanese, and by Armen Taylor in English.

Element 4
The Element 4 (エレメント4) are Drakken Joe's special forces team who maintain his Ether's balance due to his unnaturally advanced age, with each member using Ether Gear with power over one of the classical elements. Laguna and Kleene begin as members of the team, representing water and wind, respectively; in Universe Zero, Laguna's position is filled by Poseidon Nero.


 * Fai (ファイ) is a long-range sniper who represents fire in the Element 4. His Ether Gear, "Flame Ammo" (フレイム・アンモ), allows him to ignite his bullets and transform into fire. Fie is voiced by Toshiki Masuda in Japanese.
 * (ダイチ) is an alien and torture addict who represents earth in the Element 4. He uses the Ether Gear "Pain's Tree" (ペインズ・ツリー) to grow plants that inflict torture on others. Daichi is voiced by Atsushi Imaruoka in Japanese.

Madame Kurenai
Madame Kurenai (紅婦人) is the moniker of Kurenai Kôgetsu (クレナイ・コウゲツ), Homura's mother from Oedo. She first appears as the tyrannical ruler of the mining planet Sun Jewel who uses Satellite Blaze (サテライトブレイズ), a laser satellite, to execute criminals or teleport them to the labor district as slave workers. Prior to rising to power, she is enslaved for amassing debt at the casinos before being freed by Valkyrie Yuna, from whom Kurenai hides her selfish and greedy nature, allowing her to marry and assassinate the planet's previous ruler while betraying Valkyrie to her death. Kurenai is rejected by Homura after being deposed in the laborers' uprising, leaving her to be captured by a vengeful man whom she previously disfigured. She dies after a year in captivity, with Ziggy using her preserved body's Ether to locate Mother. In Universe Zero, a heroic version of Kurenai befriends Valkyrie and leads a defense force that protects Sun Jewel.

Mashima named the character after the Japanese word for "crimson" (紅) in response to Homura's name, meaning "flame", as he associated both names with fire and the color red; he admitted that he did not remember the inspiration for adding "Madame" (婦人) to her title. Kurenai is voiced by Mie Sonozaki in Japanese, and by Michelle Ruff in English.

Poseidon Nero
Poseidon Nero (ポセイドン・ネロ) is a cephalopod-like alien who possesses the Empire Dice (帝国歴程), a set of dice Relics that foretell favorable outcomes at a personal cost. He also uses the Ether Gear "Wormhole" (ワームホール) to create portals that instantly transport himself and others to different locations in the universe. Nero first appears as an Oración Seis Galáctica member and the emperor of the Aoi Cosmos, who sacrificed his friends, family, and species to build his galactic empire. His former friend Ziggy kills him after destroying his dice and absorbing his Ether Gear. Nero is later restored in Universe Zero, where he is Drakken Joe's business partner and the Element 4's representative of water after abdicating to Shura, his adoptive son. Nero is voiced by Takaya Hashi in Japanese.

Poseidon Shura
Poseidon Shura (ポセイドン・シュラ) is Nero's adoptive human son and heir, and a rival "Satan Gravity" user to Shiki who was briefly tutored by Ziggy as a child. First appearing as a brutal and insane prince neglected by his father, Shura wages war against Ziggy in a conspiracy to eliminate him, Nero, and the Aoi Cosmos's robot population with the All-Link System (オールリンクシステム), a network on the planet Nero 66 that influences all machinery in Aoi when the planets are submerged in the cosmic ocean's high tide. He is killed on Nero 66 when Ziggy destroys the planet with Nero's supply of 20,000 anti-matter bombs in a failed attempt to create the time loop that would transform Shiki into Ziggy. In Universe Zero, Shura is reborn as a more compassionate figure who succeeds Nero as emperor and reestablishes the empire as a republic. Shura is voiced by Kenichi Suzumura in Japanese.

Oceans 6
Oceans 6 (オーシャンズ6) is Nero's special forces team. Besides veteran members Cyca (サイカ) and Fabiano (ファビアーノ), the four younger members are Empire Ether users.


 * Karumu Sutīrufōdo (カルム・スティールフォード) is a younger Oceans 6 member and Jinn's childhood rival who controls mist and disintegrates his opponents through his Ether Gear, "Carburetor" (キャブレター). Callum is voiced by Shūhei Iwase in Japanese.
 * Rira (リラ) is a younger Oceans 6 member and card player who uses the Ether Gear "Gambler's Rush" (ギャンブラーラッシュ) to alter the values of playing cards. Lyra is voiced by Ikumi Hasegawa in Japanese.
 * Nase (ナセ) is a younger Oceans 6 member who creates electric signals through his Ether Gear, "Eye of Horus" (アイ・オブ・ホルス), to perform hypnosis. Nasseh is voiced by Shōmaru Zōza in Japanese.
 * Mirāni Rukura (ミラーニ・ルクラ) is a younger Oceans 6 member who travels between mirrors and controls others' reflections through her Ether Gear, "Mirror Trick" (ミラートリック). Mirrani is voiced by Ayumi Mano in Japanese.

Ijuna
Ijuna (イジューナ) is Shura's secretary and a former Oasis member whose Ether Gear, "Red Destiny" (レッドデスティニー), creates red strings that influence others' love and hatred for each other. She develops Stockholm syndrome for Shura after suffering numerous tortures and humiliations under his captivity, leading her Ether Gear to romantically attach her to Shura when he begins to fall in love with her himself. Despite being freed by Laguna Husert, she remains devoted to Shura and dies with him in Nero 66's destruction. She is restored in Universe Zero, where she is engaged to Shura following a healthier relationship. Ijuna is voiced by Hisako Kanemoto in Japanese.

Deadend Crow and Cure
Deadend Crow (デッドエンド・クロウ) is a 420-foot-tall (1380 ft.) android and Oración Seis Galáctica member with whom the Edens One forms an alliance through Ziggy. He is notorious as the "Titan of Eternal Darkness" (常闇の巨人), responsible for the mass murder of over one million humans on the Yukino Cosmos planet Swan. Crow is later revealed to be a creation of Cure (キュアー), an android with regenerative powers who first appears as an officer of the Interstellar Union Army. After both are destroyed on planet Lendard, Cure reappears in Universe Zero as a Galáctica member named "Deadend Cure", but is permanently destroyed by Jinn. Cure is voiced by Seiichiro Yamashita in Japanese.

God Acnoella
God Acnoella (ゴッド・アクネラ) is the "Mother of Dragons" (ドラゴンの母), an android woman and Oración Seis Galáctica member who commands a cybernetic dragon swarm that she "births" on the Kaede Cosmos planet Lendard. She allies with Ziggy in his conquest of humanity, loaning him Möbius (メビウス), the perpetual motion machine that produces her dragons, to expand his army. She is destroyed by Elsie Crimson immediately upon revealing her true identity as Shaya Le Lendard (シャイア＝ル＝レンダード), Elsie's formerly human mother and Lendard's ruthless queen. She returns in Universe Zero as one of Void's servants, but is defeated a second time by Homura Kôgetsu.

Ziggy
Ziggy (ジギー) is Shiki's adoptive grandfather, an android who portrays the "Demon King" (魔王) at the Granbell Kingdom theme park. Introduced as a good and kind figure who broke down from old age ten years before the series' beginning, Ziggy discovered Shiki on a failed voyage for Mother aboard the Edens Zero, raising him to use his own "Satan Gravity" ability. When Shiki revisits Granbell in the present day, Ziggy reactivates with a malevolent personality that desires Shiki's death and the dominance of machines over humans, serving as an antagonist in the series. During his and Shiki's final battle on Lendard, Ziggy reveals himself to be a mechanized version of Shiki from Universe 3173, where he was sent 20,000 years into the future by a spacetime distortion on Nero 66 before using Etherion to travel back in time to save humankind from extinction, gaining amnesia in the process. Furthermore, his evil behavior is revealed to be a result of the Edens One's artificial intelligence taking control of him. After being destroyed by Shiki to break his connection to the Edens One, Ziggy is restored in Universe Zero, where he is able to prolong his and the Granbell robots' lives and avoid falling under the ship's control.

Mashima named the character after the song "Ziggy Stardust" by singer David Bowie, which the author listened to frequently during the manga's production; the name "Ziggy" was originally given to Shiki in the story's earliest draft. Mashima noted that several readers were able to predict the character's backstory before it was revealed, although he stated that there would be "at least one" element to surprise readers due to the backstory's "complex" nature. Ziggy is voiced by Hōchū Ōtsuka in Japanese, and by John Eric Bentley in English.

Mother
Mother (マザー) is the creator of the Grand Shiki Cosmos, worshiped by space explorers as the goddess of the cosmos. She is depicted as a gargantuan woman larger than any planet, and is capable of granting any wish to those who find her. Because she exists in the hazardous outer regions of space, she is regarded as a mythical figure within the Sakura Cosmos. Shiki makes it his objective to prove her existence when he is disbelieved for his familiarity with her, while the Edens One crew seeks to kill her, as her death causes the extinction of humankind in the future of every parallel universe. Upon being reached by Shiki's crew, Mother reveals herself as the Overdrive state of planet Earth, Shiki's homeworld, transformed to replenish its Ether after constant warfare and deforestation led to the planet's ruin in the year 2025. Mother is voiced by Kikuko Inoue in Japanese, and by Colleen Clinkenbeard in English.

Elsie Crimson
Elsie Crimson (エルシー・クリムゾン) is an armored warrior who uses the Ether Gear "Star Drain" (スタードレイン) to absorb planetary Ether and convert it into battle gear or energy attacks. Introduced as a benevolent space pirate captain and Oración Seis Galáctica member who is notorious for conquering the "seven cosmic seas", Elsie delivers the Edens Zero to Shiki to repay a debt to Ziggy, her childhood benefactor. She is later revealed to be the planet Lendard's crown princess, born as Elsie Le Lendard (エルシー＝ル＝レンダード), who unintentionally caused a civil war while opposing her corrupt parents during her childhood, orphaning herself and her arranged fiancé, James Holloway. After dying with James on Lendard when the planet is consumed by the Chronophage, Elsie is reborn in Universe Zero as Lendard's queen and the Interstellar Union Army's director of operations in the Kaede Cosmos.

The character is modeled after Fairy Tail character Erza Scarlet, with her name being a portmanteau of "Erza" (エルザ) and the word "sea" to reflect her role as a pirate. Mashima commented on her and Justice's relationship, which he described as "a very star-crossed destiny". Elsie is voiced by Sayaka Ohara in Japanese, and by Colleen Clinkenbeard in English.

Xiaomei
Xiaomei (シャオメイ) is the series' metafictional narrator, who breaks the fourth wall to provide context and meta-commentary to the story. She appears within the story itself as a resident of the rogue planet Mildian called the "Time Oracle" (時読み), a "fortune-teller" with powers of omniscience granted to her by Mother, whose location is the only thing outside of Xiaomei's knowledge. To avoid boring herself with complete knowledge of the future, she limits her power so that she cannot know the outcome of any battles beyond multiple possibilities, satisfying her obsession for watching combat by putting her visitors through battles as compensation for her knowledge. She is eventually revealed to be the personification of Earth's Moon, named Luna (ルナ), whose existence is tied to Mother, the personification of Earth itself.

Mashima noted that he had to be careful adding Xiaomei into the main storyline due to her conceived role as an omniscient narrator, but found that because she "knows everything in the entire world", he was able to include her "without too much trouble". Xiaomei is voiced by Honoka Inoue in Japanese, and by Jenny Yokobori in English.

Justice
Justice (ジャスティス) is the code name of James Holloway (ジェームス・ホロウェイ), a prince and Elsie Crimson's childhood fiancé from the planet Lendard. Like Elsie, he uses the Ether Gear "Star Drain" to absorb and manipulate the Ether of planets. He debuts as an Interstellar Union Army officer who vengefully pursues Elsie for inciting the war that destroyed their home nation and families, and antagonizes the Edens Zero crew for their association with her. However, he loses his hatred for Elsie after realizing her regret for her actions, and allows himself to be erased from existence with her on Lendard when the Chronophage rewinds the planet's time. He and his engagement to Elsie are restored in Universe Zero, where the war never takes place.

Mashima modeled Justice after the Rave Master character Sieg Hart, following a "tradition" of using such characters that includes Jellal Fernandes from Fairy Tail, reflected by the character's blue hair color and markings around his right eye when his Ether Gear is active. The character's code name was selected to reflect his sense of justice. Justice is voiced by Daisuke Namikawa in Japanese, and by Robert McCollum in English.

Xenolith
Xenolith (ゼノリス) is Ziggy's mentor and the founder of the Magimech School of Gravity Martial Arts (魔械流重術), a set of techniques performed by "Satan Gravity" users in the series. His prowess allows him to control gravity in conceptual senses, such as lightening pain and causing others' thoughts to "fall" into him. Previously a human member of the Heavenly Knights of the Dancing Sakura (桜舞星騎士団), a historic group stated to have guarded the Sakura Cosmos during the universe's Dark Ages, Xenolith has since transferred his mind into a robotic body to survive one thousand years after his death. In Universe Zero, Müller steals Xenolith's powers and body to create a replica of him for the Oración Seis Galáctica, forcing Xenolith to inhabit the body of a small helper robot to survive. Xenolith is voiced by Kazuhiko Inoue in Japanese.

Saintfire Nox
Saintfire Nox (セントファイア・ノックス) is an alias used by the Church of Saintfire's archbishop, who possesses the time-manipulating Ether Gear "Cat Leaper". At the beginning of the series, the name belongs to Rebecca Bluegarden's mother and Connor's wife, Rachel (レイチェル), who is forced into the position after the death of her own mother, the previous Nox and an Oración Seis Galáctica member. Around Rebecca's birth, Rachel abandons her family to prevent her church's fanatics from killing them for their forbidden relationship, exhausting her ability to reverse time after thousands of attempts to avoid their deaths. She becomes one of numerous human mothers captured by Ziggy in Universe 3 to extract their Ether and locate Mother, allowing Rachel to reunite with Rebecca and Connor after being rescued by the Edens Zero. In Universe Zero, Rachel becomes the Interstellar Union Army's director of operations in the Yukino Cosmos, who fosters the army's support of the Edens Zero after regaining her memories of the previous world.

Oración Seis Galáctica
The Oración Seis Galáctica (Spanish for "Galactic Prayer Six"), known in Japanese as lit. "Galactic Six Demon Generals" (銀河六魔将), are a group of six powerful outlaws who are described as being capable of "crushing" planets. Elsie Crimson, Drakken Joe, Poseidon Nero, Deadend Crow, God Acnoella, and Saintfire Nox are introduced as members, while Shiki and Ziggy are branded as members over the course of the story.

In Universe Zero, the Galáctica are a faction of androids commanded by Void, which includes Cure, God Acnoella, a fake Xenolith built by Müller, and three others Joker Helix (ジョーカー・ヘリックス), an artificially intelligent game engine that slows time and creates video game-like dimensions; Lightning Law (ライトニング・ロー), who manipulates electricity and controls other androids; and Lady Freyja (レディ・フレイヤ), a soldier programmed with knowledge of every armament and battle strategy.

Shooting Starlight
Shooting Starlight (流星の灯) is an adventurers' guild on the planet Blue Garden that Shiki joins, with Rebecca, Happy, and Labilia beginning as members. The guild master is Noah Glenfield (ノア・グレンフィールド), the director of the Galactic Intelligence Agency's Sakura Cosmos branch, who uses Ether Gear to observe people's positions across space and time. With the exception of receptionist Clarisse Layer (クラリス・レイヤー), the guild's members are depicted as being unfriendly towards each other.

Interstellar Union Army
The Interstellar Union Army (星系連盟軍) is the cosmic government's military and peacekeeping force. Its six elite officers form an organization called the Oración Seis Interstellar – simply called the Oración Seis (星系六祈将) in Japanese – to combat the Oración Seis Galáctica. Besides Justice and Cure, the team's members are Jaguar (ジャガー), Holy (ホーリィ), Eraser (イレイサー), and Feather (フェザー); in Universe Zero, Justice and Cure are replaced by Victory (ビクトリー), a subordinate of Justice in the previous world, and Amira (アミラ), an agent of the army's Galactic Intelligence Agency (G.I.A.). Other officers include Seiji Hôjô (セイジ・ホウジョウ), a member of Oedo's shogunate family codenamed "Creed" (クリード), and Jesse (ジェシー), a G.I.A. agent within Elsie Crimson's space pirate crew.
