As the psychotic Zorpox the Conqueror, a name he came up with himself, Ron was an exceptionally brilliant villain when he was turned evil in a season three episode. His personality was almost entirely flipped and he actually became a very real and dangerous threat to everyone who dared to cross his path. When Ron was made evil by the Attitudinator, his skin eventually turned blue. His behavior was much more manic, bordering on the edge of crazy. Amazingly, as a villain, Ron as Zorpox was always steps ahead of Kim. Even Shego was impressed with Zorpox and terrified by his threat to throw her in a shark tank. Evil Ron was outstanding with using tools, building large and dangerous destructive devices, multitasking, and planning ahead. He also demonstrated the ability to predict Kim's actions, though that may have been due to being her best friend.
