Villians: Shego, Future Shego, Monkey Fist, Dr .Drakken, Duff Killigan
Kim Possible's Site
Kim originally wanted to be a baby sitter. She use the ad 'I can do anything' for it and people took her seriously, like when Mr. Paisely called her.
Kim's promise: "I'll never ditch again."
When Ron called Kim, he told her that someone needed her, and she said she won't ever ditch again. Maybe that's the reason why she became squad captain in high school.
Drakken's Preeteen Look
When Dr. Drakken uses the juvenator to turn into a preteen, we see that even with blue skin, he wears glasses and has poor teeth structure. Possibly the young drakken, even the blue one, was quite smart. That would also explain why his so-called posse laughed at him in Attack of the Killer Bebes.
