Harvey Who

Harvey Who is a Mobian Owl, a master of disguse and espionage, and the head of the Freedom Fighters' Secret Intelligence Division. He lead the SID and its operatives that were placed in a sophisticated network among Dr. Ivo Robotnik's territories, collecting information on Robotnik's current plans and operations and spreading it to the rebel groups, allowing them to make them fail with ease. Because of his success as the leader of SID, Dr. Robotnik made frequent attempts to find out the identity of the SID's leader was, as Harvey had made sure that no one outside the Freedom Fighters knew anything about him except his last name.

Head of the Secret Intelligence Division
Harvey Who and his agents had managed to infiltrate many of Robotnik's plans and schemes, allowing the Freedom Fighter groups they contacted to foil them easily. After Robotnik realised the Freedom Fighters must have had an inside man and had Snively and Crabmeat do some literal digging with a shovel, they found a Mole miner who Robotnik interrogated. He asked "Who is the head of the Secret Intelligence?" and the Mole replied "That's right!" Misunderstanding, Robotnik had his SWATbots take away the mole and went on to his next plan, the Wheel of Misfortune, which Harvey had secretly infiltrated disguised as a robot mover. He informed the Knothole Freedom Fighters of every move Robotnik made, and accompanied them when they made their attempts to stop Robotnik in his tracks and occsaionally left behind notes to Robotnik's lackeys. Later when Sonic the Hedgehog and Sally Acorn went to Renobotnik after a hard day's work, Harvey had infiltrated Robotnik's casino as a card dealer and was watching the two and slipped Sonic a card with a warning note, saving him from having his head crushed. After Sonic used static electricity to short out a particuarly large SWATbot, he collapsed and was captured by Robotnik who tied him to his Wheel of Misfortune so his robots could vaporise him, but Harvey managed to turn the lights off and saved Sonic and brought him back to Secret Intelligence Headquarters, where Sonic said he was impressed with Harvey's disguises, how he rescued him, and asked Harvey a single question: "How many licks does it take to get to the chey center of lolipop"? To which the owl replied "That information, my dear boy, is classified!" Following Robotnik's death at the hands of Sonic the Hedgehog, the re-formation of the Royal Secret Service and open war being declared with the Eggman Empire, the SID has likely been dismantled and Harvey retired as leader.
