Ridong was a fair-skinned man with short black hair and a red tuft of hair hanging over the front of his face. He wore dark garments and wielded a sword.
Ridong walked out with the rest of Team Mad Dog for the Development Tournament as they readied to battle Team FUG. Later in the tournament, when he and Viviolga attempted to kill Novick, Kang Horyang burst out of nowhere and blasted him and Viviolga into oblivion.
