Doctor Con is a more powerful version of Professor Scam, Eddy's supervillian alter-ego. He has the same powers as Professor Scam, but now he dons a greyish-white nehru jacket, and a pair of bionic hands. He is based on the James Bond villian Dr. No.
Dr. Con is considerably more powerful than Professor Scam. As he shown developing a powerful energy source without Edd's help. He also has superhuman strength, this is shown in an episode of Ed, Edd n Eddy: Right Back at Ya!, when he is fighting Captain Melonhead, he punches through a brick wall with little effort.
