Until General Hawk came on board, G. I. Joe took its orders from the Colonel. The gravelly-voiced Sharp had grey hair and glasses, and wore a beige officer's uniform. Sharp thought very highly of the G. I. Joe team but tended to be pessimistic in crisis situations. Colonel Sharp spoke 46 lines in 11 episodes, with 12 total appearances: The Revenge of Cobra parts 2 and 3, Cobra Stops the World, Cobra's Candidate (voice only), The Synthoid Conspiracy, Part I and II, The Germ, Captives of Cobra (Part II), The Wrong Stuff, Pit of Vipers, The Invaders, and Skeletons in the Closet.
