Kintaros is the physically strongest of the Imagin that are linked to Ryotaro and speaks Kansai-ben. He originally possessed a man named Masaru Honj�, but joins Ryotaro when Den-O is unable to defeat the Rhino Imagin. He is mostly found sleeping on the DenLiner, but will possess Ryotaro whenever he hears someone say anything resembling "cry" (泣�る� nakeru de). As Den-O, he lives up to his namesake and fights with an axe as Axe Form, has primary control of the left arm in Climax Form, and his power is tapped in the DenKamen Sword's KinAx mode.
Urataros (ウラタãƒã‚¹ Uratarosu) is the second Imagin that gives Ryotaro his power, allowing transformation into Den-O Rod Form. The form given to him by Ryotaro is turtle-like in appearance, with his weapon being the Uratarod (ウラタãƒãƒƒãƒ‰ Urataroddo), a rod with hexagonal blades at each end. Furthermore, Urataros was well-aware of Ryotaro being a Singularity Point, making his contract to him on purpose—though he says it is to evade the loneliness of being outside time, Hana later debunks this entirely. When he possesses Ryotaro, he usually states the words, "Hey, will you let me fish you?" (ã�Šå‰�ã€�僕ã�«é‡£ã‚‰ã‚Œã�¦ã�¿ã‚‹ï¼Ÿ Omae, boku ni tsuraretemiru??).He is also aware of the evil Imagin planning to destroy time, but simply does not want to commit it as in spite of his cool exterior, there's indication that he's somewhat of a coward and lies just for self preservation. Urataros is a casanova with a very convincing personality, owning the ability to convince almost anyone by speaking to them, with Ryotaro the only one who trusts him and lets him stay as he sees he has a good heart. Urataros, however, later says that he lies simply for the sake of lying ("One lie is more interesting than a thousand truths"), and seems quite irritated that Ryotaro is "trivializing his lies." While Momotaros gets Ryotaro in trouble through reckless methods, Urataros puts Ryotaro in conflicting situations when he goes around wooing multiple women. Despite these negative traits, along with his occasional fights with Momotaros, Urataros does show genuine concern for Ryotaro's well being the best speaker of the Taros, possessing Ryotaro simply to get information out of someone, or to talk his way out of something. He is also useful in situations that require patience, something Momotaros severely lacks. He usually refers to Momotaros as "Sempai" (先輩 Senpai?) and Kintaros as either "Bear" (クマ Kuma?) or "Kin-chan" (ã‚ンã�¡ã‚ƒã‚“ Kin-chan?) respectively. Urataros' physical form based on that of a turtle and fishing rods are a common motif, both of which are aspects of the myth of Urashima TarÅ� (浦島太郎?), a fisherman who caught a turtle that led him to the castle of RyÅ«jin.
Sieg is an Imagin who enables Den-O's transformation into Wing Form. He arrives in the current timeline six months prior to Ryotaro becoming Den-O, originally intending to forge a contract with a young wealthy pregnant woman named Shiori Takayama, but possesses her unborn son in the process. After the child is born and subsequently kidnapped, Sieg comes into being and seeks to reunite his "brother" with their "mother", crossing paths with Ryutaros and gaining access to the DenLiner. Due to his "privileged" upbringing and his already princely mannerisms, Sieg becomes easily infuriated when treated with disrespect. Because he is "born" in 2007, he also possesses extraordinary unique abilities. Aside from shrinking the TarÅ�s to 4 inches tall with the phrase "Kneel down to me!" (é ã�Œé«˜ã�„! Zu ga takai!),he also cannot be forcibly removed from Ryotaro's body as he does not need a contract to possess humans. When possessing Ryotaro, Sieg says "Descending, yet above it all…" (é™�臨ã€�満をæŒ�ã�—ã�¦… KÅ�rin, man o jishite…). He almost vanishes due to his contract holder being a newborn child and unable to form proper memories, but Ryotaro is able to discover that Sieg actually made a contract with the mother to ensure her then unborn son's safety, saving Sieg's life in the process. As his contract has been fulfilled, the DenLiner takes Sieg to the date of his Shiori's greatest memory and lives in the past freely. After his appearances in the television series, he appears in the films Kamen Rider Den-O: I'm Born! and Saraba Kamen Rider Den-O: Final Countdown allowing for the transformation into Wing Form, and again in Cho Kamen Rider Den-O & Decade Neo Generations: The Onigashima Warship, pestering Tsukasa's group until brought to the climatic battle to join the TarÅ�s in forming Super Climax Form. He also appeared in Cho-Den-O Trilogy Episode Blue: The Dispatched Imagin is Newtral. During his first time on the DenLiner, he demanded that the others call him "Prince" (プリンス Purinsu?) and asked for Hana to be his "Princess" (å§« Hime?), and was punched for each time he called her that. After his return, Sieg refers to the TarÅ�s as his "family" instead of his "friend" phrasing. In the Imagin Anime OVA, Sieg had an additional power "Super-Ultra Kneel down to me!" (スーパーウルトラé ã�Œé«˜ã�„! SÅ«pÄ�-Urutora Zu ga takai!?) that allows him to shrink everything in sight, even an entire planet. His name is given as "Zieg" in the series' photobook DETAIL OF HEROES: Masked Rider Den-O Exclusive Photograph Collection: IMAGINE (DETAIL OF HEROES ä»®é�¢ãƒ©ã‚¤ãƒ€ãƒ¼é›»çŽ‹ç‰¹å†™å†™çœŸé›† IMAGINE DETAIL OF HEROES Kamen RaidÄ� Den'Å� Tokusha ShashinshÅ«: Imajin?), however, other materials give his name as "Sieg," such as the earlier photobook Masked Rider Den-O Photobook: IMAGIN (ä»®é�¢ãƒ©ã‚¤ãƒ€ãƒ¼é›»çŽ‹ãƒ•ã‚©ãƒˆãƒ–ãƒƒã‚¯ IMAGIN Kamen RaidÄ� Den'Å� Fotobukku Imajin?). Sieg's physical form and name are based on swan and Prince Siegfried (ジークフリート王å� JÄ«kufurÄ«to ÅŒji?) from the story Swan Lake (白鳥ã�®æ¹– HakuchÅ� no Mizuumi?).
Aries is a timid female, very softspoken and shy. In the past, Karen the Celestial Spirit mage forced her to do many horrible things and generally abused her, such as using her as a shield (Because, apparently, she has no fighting abilities) and using her to lead away all of her boyfriends instead of simply refusing them. Loke arc Three years prior to the story, Aries was owned by Karen Lilica. In Loke's flashback, Aries was treated horribly by Karen. She used her to keep her "boyfriends" away from her. She tries to protest but she is too intimidated by Karen. Blue Pegasus Guildmaster Bob sees this and warns Karen to take care of her spirits. In a rage, she accuses Aries of ratting her out and apparently physically assaults her, although all that is seen is Aries getting shoved to the floor. Karen threatens to keep Aries in the human world for a week, but before Karen can act on this threat, Loke steps in by summoning himself to take Aries' place (Since Karen could only maintain one spirit at a time) and tells the Celestial Spirit Mage to break her contracts with Aries and himself. When she refuses, Leo threatens to remain in the human world until she agrees, rendering Karen unable to summon any other Celestial Spirits. Karen continues to refuse, since she believes that he cannot remain in the human world for a long time; however, Leo leaves her with the ultimatum and goes to a deserted chapel where he stays for three months, attempting to get Karen to break the contracts. When Leo returns, he learns that Karen was killed on a mission and that Aries' key was taken. Oracion Seis arc After an exchange in the Spirit World, Aries is summoned to battle with Loke and Lucy Heartfilia. Despite the two not wanting to fight one other, they choose to fight for the sake of their pride, and the battle begins. However, due to Aries' non-combative nature, she fights a losing battle to Loke. As the battle progresses, Angel summons Caelum and uses it to blast through Aries and hit Loke, causing them both to return to the Celestial World for healing. After her defeat, Angel is arrested and her contracts with her spirits are broken. Aries, along with Scorpio and Gemini, seek out Lucy and form contracts with her instead. Edoras arc Lucy summons Aries to prevent the Edoras soldiers from capturing her and her friends. Aries then proceeds to attack the soldiers with a technique called "Wool Bomb", which allows Lucy and company to escape.
Scorpio is a Celestial Spirit that is one of the 12 Golden Zodiac Keys. His key is currently owned by Lucy. He is also Aquarius's boyfriend with which he has a happy relationship. His weapon appears to be a large, strange gun shaped like a scorpion's tail. Scorpio has a strange manner of speaking which is similar to the third person where as he says "We are" in the beginning of each sentence. Scorpio has also a habit of folding his middle and ring fingers back while keeping his index and little fingers extended, mimicking the pincer claws of a scorpion. Unlike Aquarius, Scorpio hasn't shown any hostility or dislike towards Lucy. In fact he seems to genuinely respect and care for Lucy.
Yeagar (イエーガー Iēg�) is a Mage of the Quatro Cerberus Guild. Yaeger seems to employ plants in battle. Yeagar has proven himself capable of summoning forth large carnivorous plant-like objects from the ground, shattering it in the process. Such seeming flytraps, which consist of four massive "petals", with a row of rounded teeth on their inner sides and massive spikes on their outer ones, are roughly the size of a human, and damage enemies by suddenly closing themselves on them, being shown sending them flying away with brute force.
