Geoffrey St. John

Geoffrey St. John was the leader of the Kingdom of Acorn's Royal Secret Service. Following the organization's destruction at the hands of Dr. Ivo Robotnik, Geoffrey reestablished it in honor of his father,Ian St. John, who was also his predecessor. Following Robotnik'smilitary coup, he gathered the few remaining members of the old Secret Service and formed them into the Rebel Underground, an organization originally proposed to King Maximillian Acorn but never put into action. After some time working independently, his group met the Knothole Freedom Fighters, and after a number of meetings began working together with them. For a time, Geoffrey even contended with Sonic the Hedgehog for the hand of Princess Sally Acorn, but eventually found his true love in Hershey Cat, a member of the new Secret Service team formed following Robotnik's defeat. Since then, Geoffrey has been leading missions against Dr. Eggmanand other villains in the service of former king Max and later KingElias Acorn. However, he later went rogue, restoring the wizard Ixis Naugus to full power and working as his apprentice; who he actually had been in league with for years.

Geoffrey was extremely egotistical, self-righteous and uncompromising, often belittling Sonic and other members of the Freedom Fighters as mere children, rarely hesitating to make insinuations against others. He would even end up in physical conflicts with Sonic, Antoine and others due to his attitude. He holds an intense hatred of Overlanders due to them being involved in his father's death. While determined to do the right thing, sometimes his sense of self-righteousness causes him to be pushy or make poor decisions concerning others. He tries to come off as both suave and businesslike, though he isn't above casual taunting. His personality has become somewhat more relaxed since Sonic's year-long absence and his marriage to Hershey.
