Absolute Anime

Apollo is the main character of Aquarion. Apollo is an orphan who lives with four other orphans. When Apollo was little, his best friend Baron gave him his name as reference to the Mythical God of the Sun. Due to Apollo's situation, he has gained a keen sense of smell and an ability to hunt like an animal. Apollo is rude, easy to anger, and gets into fights with another element user, Sirius. As the story progresses, Apollo shows great ability in piloting the formation Solar Aquarion and has developed many different attacks such as Infinity Punch and the combine attack involving Silvia and Sirius.

Apollo is really the reincarnation of the hero of Atlantis, Solar Wing, also known as Apollonius. Apollonius was a Shadow Angel, which is a race of beings that look down upon the humans or the Wingless Ones. They harvest the humans for their energy so they can stabilize the Tree of Life and their own lives. After Apollonius betrayed the Shadow Angels and fought against them, he was reincarnated into Apollo 12,000 years later.

At the ending of the anime, as the Tree of Life was dying, Apollo came to the decision to sacrifice himself along with Sirius and the Shadow Angel Toma to save the world from destruction. He promised Silvia that he will return in the next 12,000 years, after being reincarnated.
