Shego: (Singing) In the shadows, I lurk and roam, A villain with a heart of stone. I'm not your average foe, you see, I'm quick, I'm sly, I'm Shego, that's me. With plasma powers, I'll bring the heat, Defeating Kim Possible, oh, what a feat. I'll outsmart, outmaneuver, and outplay, I'll make her rue the very day. But why, oh why, can't I resist, This teenage hero and her little twist? I feel a spark, a flicker, a flame, A longing for something I can't name. So tell me, Kim, Why do you...
