He has grey feathers except for white head feathers, dark eyes, white beard and bald spot. He wears maroon vest and glasses.
Sonic the Hedgehog encountered him during one of his many missions, and the elderly eagle thought himself the last eagle on Mobius to survive Dr. Ivo Robotnik's predations. Too weary to even fly, Cyril had all but given up, but Sonic motivated him to try flapping his wings again. Amazingly, Cyril got the hang of it again, and even found surviving members of his rookery. Together, they helped Sonic survive one of Robotnik's many attacks. (StH: #12)
Cyril later appeared in Knothole and was training the other Substitute Freedom Fighters when Larry Lynx arrived with dire news about Sally Acorn's Knothole Freedom Fighters. Despite his advanced age, the eagle willingly submitted to Larry's command and followed the others in liberating their trapped friends. (SLV)
