The main protagonist. Apollo is an orphan that has grown up in a group of homeless children. His name was given to him by his best friend Baron, who acted like an older brother to him for most of his life. Apollo possesses a kind heart and a noble spirit behind his rude, aggressive and bestial behavior. He has very sharp reflexes and senses, similar to an animal. His characteristics cause few to believe the rumor that he is the reincarnation of Apollonius, also called the "Solar Wing"
The group's number one geek and otaku. Has the ability to see through solid objects with his "Mind Eye Photography" technique which allows him to quickly target the weak points of enemies. Excels in handling computers and machines. Like Tsugumi, Jun rarely enters in action, spending most of the time operating the computers at Deava's control room.
A shy girl with a sad past. With the ability to explode things from a distance when her pulse reaches its peak, she was always estranged from friends and family. Because of her power, over which she still doesn't have full control, she sometimes creates some accidental explosions. This scenario started to change when Tsugumi found some real friends in Deava, including her roommate Reika, for whom she has great affection
The main antagonist and Apollonius's previous partner. Even 12,000 years later he could never forget his treason, and still has feelings for him. Because of it he is one of the Angels who despise humans at most. He plans to use Aquarion's power to repair the tree of life, but in order to make it possible, he needs to make Aquarion manifest the true power of the "Solar Wings", and thus he prepares ordeals and trials to the elements, especially Apollo, in order to make them stronger
Touma's faithful servant, she loves him with jealousy. She hates Apollonius and Celiane, not only because they destroyed Atlantis 12,000 years ago, but also because their love makes Touma suffer so much
She is a sensitive girl who has the strange ability of causing misfortune to those around her. This causes most people to avoid approaching her, with the exception of Sirius who nurtures strong feelings for her. Reika tries to avoid contact with people in general because she believes that her misfortune caused an accident that put her boyfriend Glen into a coma. She is the reincarnation of Scorpius.
Kojima Genta is a student in Teitan Elementary when Shinichi joins his class as Edogawa Conan. Shortly afterwards, he and his classmate Ayumi decide to investigate an apparently haunted mansion, and they persuade Conan to come along. When their friend and classmate Mitsuhiko expresses his skepticism about supernatural hauntings, Genta forcefully 'persuades' him to tag along as well. As it turns out, the haunting is a cover-up for an old homicide case. Soon after, the accidental acquisition of a treasure map leads Ayumi, Genta, Mistuhiko and Conan on a hunt for a cache of stolen Italian gold coins, during which Conan saves them from getting killed by the mafia members who are also after the gold. After the case is resolved, Mitsuhiko joins Genta and Ayumi in forming the nucleus of an amateur detective group, the Detective Boys. Genta is quick to pronounce himself the leader of the group, but his lackadaisical leadership abilities are commonly neglected in the field, and in fact everyone (even Genta) unconsciously views Conan as the group's actual leader. Genta's school shoe locker is used as a mailbox for any of their fellow students to present them with a case to solve. Genta loves food, especially unagi, and can eat more than all the other Detective Boys members combined. When discussions of money come up, Genta tends to think about it in terms of how many unagi bowls he could buy. He also tends to mess up certain Japanese terms with similar-sounding words (especially if the latter are related to food) and sometimes has trouble reading even the most common Kanji, which on occasion causes some ridicule from his classmates and friends. His brash personality, lack of awareness of his surroundings, and tendency to not think before acting often lands the Detective Boys (or at least himself) in sticky situations. Even though he is brash, outspoken and can be intimidating, Genta is actually very kind and dependable. He is a good friend of Ayumi and Mitsuhiko, and has been shown to greatly admire his father, who is considered to be a classic "Child of Edo". (Source: Detectiveconanworld.com)
