It looks similar to a red-colored Egg Pawn with no legs. It carries a staff and has a skirt-like covering meant to resemble a robe in the place of legs.
The Egg Bishop first appeared in Sonic Heroes and is only encountered in Hang Castle and Mystic Mansion. It can be easily destroyed, however it replenishes enemies health. It has something of a split personality; when performing a Tornado Jump on an Egg Bishop, it causes it to flip over and become an E-1010 Egg Magician. This is only true in Sonic Heroes, since the Tornado move is impossible to perform in Sonic Rush.
