Drakon has a dragon-like appearance, with scales and green skin. He is particularly taller than most humans, but shorter than Hinahoho. He has amber eyes. First seen in Adventure of Sinbad, Drakon appears to be a young man with long dark green hair, cropped short around his face, amber eyes, and a single hanging earring on his left ear.
Sinbad has stated that despite his appearance, he was once a human and a sincere man.
When Drakon was the Parthevia Empire Army's Commander Officer, he had a strong sense of patriotism and greatly disliked the ways of his brother. Drakon came from the Parthevia Empire. Since he was a child, Drakon had a close relationship with the First Imperial Princess, Serendine Dikumenowlz Du Parthevia and used to follow her around.
He became a Parthevia Empire Army's Commander Officer at 14 (he still had human aspect), as his family has been generals for many generations. When Baal's Dungeon appeared on Parthevia, the Emperor wanted to obtain its power, since Parthevia was in war against Reim Empire. All the soldiers who were sent to the Dungeon died, and the Emperor also decided to send Drakon. Drakon recruited more people among the population, and one of them was Sinbad, with whom he didn't go along well. In the Dungeon they found many obstacles, and the only ones who reached the treasury were Drakon and Sinbad. Baal appeared in front of them, and the two boys fought each other, agreeing that the one who won would obtain Baal's power. Sinbad defeated Drakon and became the first dungeon conqueror. In that point, Drakon was beginning to recognize Sinbad. When he returns the Parthevia's Emperor is angry with him because Sinbad obtained the Metal Vessel, and orders Drakon to capture Sinbad.
It's unknown when his aspect changed. Only few people along with Sinbad and his wife know what he was like as a human.
