the heroine on her fashion and dating choices and is found attractive by both Ron and Senor Senior Junior, who are both of a high school-college age. Still, at other times she seems to be quite a bit older, having a complex college degree in child development, dating Mister Barkin, in Sitch in Time, Shego has the same white stripe in her hair as Drakken, Monkey Fist, and Kim's parents, indicating she's older, and being characterized by Ron as "older, like, a lot older!" Of course, this also comes in the same scene in "Clean Slate" where Shego tries to convince an amnesiac Kim that she was a senior while the heroine was a freshman.) During the fourth season, Shego's character went through some development which pointed to the possibility that she may have been growing tired of her established role as a villainous sidekick. She walked out on two separate capers, and on two occasions she actually saved Kim's life. Shego states her reason for doing so is because nobody is allowed to kill Kim, except for her. Finally, at the series' end, she and Drakken team up with Kim and Ron to save the world from an alien invasion. Because of this, she is greeted as a heroine once again. Relationships Kim Possible Shego has a powerful rivalry with Kim on the battlefield, which is sometimes kept at a "professional" context, but usually involves a few insults. This rivalry, however, progressed along the series, becoming more and more personal for both fighters. Like Bonnie, Shego talks down to Kim as if she were a child, often referring to her by the diminutive "Kimmie" or nicknames like "Princess" or "Pumpkin", as well as putting down both her appearance and wardrobe. However, Kim doesn't seem to be quite as affected by Shego's insults as with Bonnie's, and her retorts have a better effect against Shego. Over time, and despite their rivalry (or possibly because of it), Shego has developed a professional respect which she often shows for Kim as a rival and a fighter, and is less than impressed when she manages to ruin Drakken's scheme. In some instances they share a bond, especially when they are stuck in the same "sitch", usually leading to small and almost friendly conversations. This relationship has somehow grown to be much more personal for Shego, also indicating a gradual development in her personality.
