Gardon is a gray-furred Mobian koala with droopy ears. He has a white-furred muzzle and hands, and possesses a large black nose. He also has small, black, bead-like eyes. For attire, he wears a matching sky blue two piece uniform, consisting of a hat with a rim and a vest with a yellow collar and latches. He also wears brown shoes with gray soles.

Gardon is very devoted to his duty and Blaze, and expresses a great deal of concern for the princess' well-being as he asks Sonic to take good care of her. He also holds great respect for Blaze, addressing her as "Your Highness" (which often annoys her) and "Princess Blaze" when in her presence.
