Main

Jin Kamishina is an 18-year-old boy who, two years prior, lost his family (his parents and younger sister) in a space shuttle accident. He was the only known survivor, who mysteriously had no major injuries, despite falling from a high altitude. To make matters worse, the ISDA had also reported that the shuttle incident was due to pilot error (Jin's father, the pilot, being blamed). Since then, he has lived a solitary existence, being shunned by people, and feeling as though he was all alone in the world. However, this all changed after he meets Toa, who becomes the first person in two years that he connects with. It is also later revealed that Toa was the one who saved Jin from falling to his death during the shuttle incident, and that, at that time, he also underwent a successful Resonance with her. However, Toa also reveals that she too was the one responsible for the space shuttle accident, which killed Jin's family and the others. Despite this, Jin still continues to protect her. In the manga, Jin's character is drastically different compared to his anime counterpart. When dragons invaded Earth, his family was killed in the destruction of Tokyo two years prior to the story's beginning. Due to this, he seemingly becomes cold-hearted and vengeful, showing no mercy when destroying invading dragons. He is considered to be one of the most dangerous of the Dragonauts when he actualizes with his partner Toa, whom he often insults (albeit, in a seemingly comedic nature). He is also shown to have some athletic abilities of his own. Despite his stoic attitude, he strives to protect mankind with the power [Toa] he has gained.

Toa is a mysterious girl who, two years after the space shuttle accident, saves Jin from a dragon who was feeding on a woman in its semi-transformed state (half humanoid, half dragon). Toa is shown to have remarkable athletic abilities, extraordinary strength, and accelerated healing capabilities, even showing to be able to heal others as well; all of which are attributed to the fact that she is a dragon from Thanatos. In her Dragon Form, she is immensely powerful; she is able to take on more than two other dragons at a time. She is referred to as the "Album" by the ISDA, who wishes to capture her in order to retrieve information on the original dragons from Thanatos. She calls Thanatos 'mother', and her mission on Earth is revealed to be the retrieval of the Earth-made dragons possessed by the ISDA. She later admits to being one of the three dragons that collided with the space shuttle that day, which killed Jin's family (plus everyone else on it). She got the name "Toa" after retrieving half of a bracelet that belonged to Jin's sister, Ai. Before the accident, the bracelet had "To Ai" engraved on it, but now it only reads "To A", which is where she got her name from. She also bears a relatively bright "stigmata", which signifies her impending death; the brighter it glows, the closer she is to death. However, her stigmata disappears in the final episode. Toa is a Barrier-Type dragon. In her Communicator (human) Form, she can create a shield strong enough to repel a fully actualized dragon. In her Dragon Form, she mainly disables her opponents by locking them in barrier spheres. In the manga, she is part of the Dragonauts and is partnered with Jin, with whom she had Resonated with two years ago right after hatching from her egg. Though she possesses all the abilities as her anime counterpart, she is shown to be very klutzy, which often infuriates Jin. Despite Jin's seemingly cold attitude towards her, she remains very loyal to him.

Gio is a dragon from the ISDA who is assigned to be Kazuki Tachibana's "partner" after Kazuki successfully resonated with Gio's dragon egg form. However, despite being Kazuki's partner, Gio does not take orders from him, showing more concern for Toa, whom he states he was born to protect. Due to this, he is considered to be a failed experiment. His attachment to Toa seems to stem from the fact that he awakened early to Toa's cry when she first actualized in the series. After Toa runs away he assists Jin in finding her eventually ending up on Mars. During a battle on Mars after seeing Akira killed and Machina falling to her death, his energy drastically increased while in his dragon form, and he created an explosion that caused the planet to burn; a phenomenon that can still be seen from Earth even a year later. During the time skip he lived with Toa and Jin and got a job. He seems to have developed an interest in cooking. Later, when he returns from his brief visit to Thanatos, his personality seems to have shifted, as he attacks his former comrades, and claims to be Thanatos's successor. However, he had only done this in order to ensure that Toa does not die. He would once again help his friends stop Thanatos, and in the end, he leaves Earth. Where he went to, is unknown. Despite initially finding Jin to be a nuisance, he later forms a bond with him due to their shared feelings for Toa. After realizing how Jin and Toa feel for each other, he takes a supportive role, and tries to protect the two from danger. However, he still has lingering feelings for Toa, resulting in him feeling isolated from the two. Gio is a sword type dragon. He is able to create a black sword while in his Communicator form. His finishing attack as a dragon is a passing slash with a sharp horn that he extends. His name is derived from his code-number, "G10", which Kazuki misread as "Gio". In the manga, he makes his first appearance as Kazuki's dragon partner.

International Solarsystem Development Agency (ISDA)

Kiril is the leader of the D-Project, and is the man in charge of finding ways to destroy Thanatos.

Sakaki is a soldier working for the ISDA as the Dragonauts' military commander. He had been the one that suggested the use of dragons in destroying Thanatos, and believes that the D-Project should go public. He remains to work for the ISDA even after it falls under Gillard command, believing all dragons are a threat to Earth's safety. Despite this, he uses a dragon, who looks like his deceased daughter, to capture other dragons. Though he considers her to be a tool, he sometimes shows concern for her, even admitting his love for her when she chooses to stay by his side. He witnessed the death of his wife (Martina) and daughter (Laura), who were on the same shuttle flight as Jin's family.

Laura

Laura is Sakaki's dragon counterpart, often calling him her father. She initially remains hidden in Sakaki's apartment, but works with him to capture other dragons a year later. Though he treats her like a tool, she remains completely loyal to him. She wears a mechanical suit for battle, and possesses the stigmata, She is revealed to be "Raum", the final original dragon from Thanatos. She apparently lost connection with her original dragon form after completing a Resonance with Sakaki, which is why she only battles in a mechanical suit. Her original form was the dragon encased in the giant tube at the ISDA, but that is destroyed by Nozaki.

Lindworm Unit

Raina is the leader of the Lindworm Unit, having joined them in order to test his potential, which was encouraged by Jin's father, who had recommended Raina for the D-Project. He is also a Dragonaut whose partner is Howlingstar. He and Howlingstar defects from the ISDA after it falls under Gillard command. He is the ISDA's public representative, and is quite popular with girls, often receiving presents when he appears in public.

Howlingstar is Raina's dragon partner and the leader of the Communicators in the Lindworm Unit. He is the most energetic of his fellow Communicators and often likes to show off his skills. He is a spear type dragon. He can create a massive spear as his weapon of choice. In his dragon form, he is red colored with his wings forming two half-cones, that he can combine to make his finishing move, a high speed charge that pierces through the enemy.

Akira is a Dragonaut for the Lindworm Unit. She has a close relationship with her dragon partner, Machina, whom she believes to be the ideal woman that is the exact opposite of her, and who also acts more like an older sister towards Akira. However, she has always been hesitant to love Machina, as the latter is a dragon, but after meeting Jin, she realizes that the relationship between dragon and human can become much more. Due to this, she often helps Jin, even to the point of betraying the Lindworm Unit. However, she still considers its members to be her comrades, and does not let her betrayal get in the way of helping them when need be. She is killed by Garnet in episode 16. When she dies in the anime at the hands of Garnet, Machina encases both herself and Akira in ice. Later, they both merge with Thanatos as part of its soul, though they both seem to lose their real identities. At the end of the series, Thanatos leaves Earth in peace and when the dragonauts are overjoyed that they saved the world, the spirits of Akira and Machina are seen as they smile at each other knowing that humans and dragon can coexist, and with that their spirits flew away. In the manga, Akira is the newest member of the Dragonauts, being the latest to complete a Resonance. She also expresses a direct liking for Jin, clashing with both Toa and Sieglinde.

Machina is Akira's dragon partner, who acts like a big sister towards Akira, correcting her speech and keeping her in check. She states that she follows Akira because she wants to, not because Akira is her master. When Akira dies, Machina goes berserk in response, but later encases herself and Akira in ice, though merges with Thanatos as part of its soul a year later. When Thanatos leaves Earth to be in peace, Akira and Machina's spirits are seen as the two of them smile at each other as they knew that humans and dragons can live in peace, and with that their spirits flew away. Machina is a water type dragon. She has the ability to manipulate water when in her Communicator form. In her dragon form, she can attack with liquid whips and also with concentrated balls of water, along with unleashing countless ice crystals from her wings. These attacks seem particularly effective against fire-type elements.

Sieglinde is the heir to the Baumgard family fortune, and is a child prodigy, having entered college at the age of nine. She is chosen to become a Dragonaut for the Lindworm Unit, and her dragon partner is Amadeus, who is named after her now-deceased dog. Due to her studies, she has been lonely since her youth, and she considered her dog to be her only friend before it died. She and Amadeus defects from the ISDA after it falls under Gillard command. Despite her seemingly cold attitude, she considers some members of the unit to be her family, and lives in the ISDA facilities. She seems to have feelings for Jin. In the manga, Sieglinde is transferred from America to the Dragonauts team in Japan.

Amadeus is Sieglinde's dragon partner, who seems to act more like her butler. Despite his elderly looks, he is a competent fighter and cares deeply for Sieglinde, constantly worrying for her safety. His name is based on the name of Sieglinde's now-deceased dog, and his appearance is similar to Sieglinde's grandfather. His name and appearance might also be a reference to legendary Austrian composer Wolfgang Amadeus Mozart. He is a gravity type dragon. He is able to unleash large bursts of gravity in his Communicator form. He has a bulky form as a dragon resembling a bomber, which does not hinder his ability to fly, and he attacks with bursts of gravity waves.
