Dr. Drakken is a character from Kim Possible.
He is a blue-skinned mad-scientist and super-villain obsessed with world domination, and with proving that he is a genius. Often referred to as Kim Possible's arch nemesis and, alongside Shego, the main antagonist of the show. His real name is Drew Theodore P. Lipsky. He became a villain after being mocked by his friends at college, among them Kim's father, Dr. James Timothy Possible, his former college friend. He has blue skin and black hair in a mullett hairstyle (often kept in a pony tail). He also has a scar on his left cheek.
Although clearly a genius when it comes to science and schemes, Drakken lacked the smarts to apply them correctly, and usually ended up portrayed as an incompetent loser and comic relief; nonetheless, his determination kept bringing him back with his plans. Drakken himself usually claimed to be evil, yet, there were occasions in which he showed a soft side of himself. Some running jokes were that no matter how many times he met Ron Stoppable, he could never remember Ron's name, and he would always be surprised when he met Kim Possible (in the Kim Possible movie Kim Possible: A Sitch In Time, Monkey Fist asked Drakken why he always acts so surprised to see Kim Possible).
