Lucy Banner is a girl who transfers into Ms. Wigglebomb-Flores' class. Whenever she displays any type of emotion she transforms into something else, most notably, when angered she'll transform into a green hulking figure after exclaiming "You don't want to see me when I'm angry." She then follows suit with her other emotions, exclaiming "you don't want to see me when I'm [emotion]," before transforming into something else.
The source of her transformation powers has yet to be explained.
