Phelios

Each of the game's seven stages is divided into between two and four sections (the transition from one to another is indicated by a block of Japanese text appearing at the bottom of the screen and a change in music).

At the end of every stage, Apollo must also defeat a boss character from Greek myth: Medusa, the Graeae, the Siren, Antaeus, Scylla (who has taken on the form of the "Crystal Brain" from the aforementioned Bakutotsu Kijūtei), Cerberus, and Typhon himself; once he has done so, he will proceed to the enchanted mirror at the back of the boss character temple, before the game segues into the next stage.

If the "rank select" option in the arcade version's option menu has been set to "on", players will also be able to select an "easy" or "hard" game mode, once they have inserted their coin, but the "easy" mode only features the first four stages and does not feature the game's complete ending sequence as a result of it.

The player takes control of the knight Apollo, the god of the sun, who sets off on the legendary winged horse Pegasus, to rescue his lover, Artemis, the goddess of the moon, from the Titan, Typhon.

The game shows players an Artemis that acts as a princess (but in Greek mythology, she was the goddess of the hunt, and took pride in never being with any man).
