Clad in shining blue armor and with his sword and shield always at his side, Concavalier is the heroic, gallant, and chivalrous knight of his age. He rides across the land, fighting for justice and righting wrongs anywhere he finds them, and asks for nothing in return other than the joyful exhilaration of those he has helped. With so many good deeds to perform, even Concavalier can get confused sometimes. He means well, but he occasionally does try to rescue dangerous Psymonsters from the royal Psymonster. Fortunately, the mythical Psymonsters are generally appreciative enough to give the kingdom of the Psymonster World back its stolen treasure.
He is a handsome knight with tan skin, black hair and eyebrows, green eyes, a blue breastplate, armored shoes, leg armors, arm armors, and a helmet with a red plume, a fancy yellow gorget, a navy under suit and gloves, a blue sword with a silver blade, and a gray shield.
- The name "Concavalier" is probably derived from the word "cavalier", meaning a horseman, especially a cavalryman.
