Dr. Drakken

Drew Theodore P. Lipsky (known commonly as Dr. Drakken) is the primary antagonist of the Disney series Kim Possible.

Drakken is noted to have blue skin, which he did not have during his past. In the episode Bad Boy, he was turned good due to a failed evil scheme, and his skin became normal. In that same episode, Ron Stoppable turned evil and his skin turned blue. Although the exact cause of Drakken's blue skin is unknown, he said in the episode Graduation that his skin became blue on a Tuesday. He is also noted to have a unibrow, a scar under his left eye, and wear a mad scientist outfit.

Drakken was picked on during his past, eventually being kicked out of college and leading him to the dark side. He is a scientist/inventor who has created numerous inventions to get rid of Kim Possible and pursue his goal of ruling the world. However, Drakken can be clueless most of the time, and his bumbling is partly the reason of his failure. In Graduation (the series finale), he and Shego supposedly redeemed themselves.
