Shada is the young priest, protector of the Millenium Key. With his powers he could look in people's minds and to find out their real face. This way he finds people with big KA. With the help of Shada, Seto uses the powers of the Key to find such people who would be an army defending Egypt.
Shada is the man who recognizes Kisarra as the Blue-Eyes White Dragon. A lot of people believe that he reincarnates as Shadi.
In the fight with Zork, Shadi throws himself in front the Pharaoh and takes the decisive blow intended to kill the Pharaoh.
