Rocky is portrayed by Zendaya and also by Jasmyn Ramos as a child in a flashback ("Shrink It Up").
Rocky is a very studious and ironic girl. She values learning, and has a perfect attendance record. Unlike her best friend CeCe, she values school and takes honors classes. She is extremely intelligent, but is more book-smart rather than street-smart, the opposite of CeCe. She is a vegetarian and believes strongly in human and animal rights. Rocky is quite reserved and thinks logically before acting, which causes her to be pushed around by CeCe to take more risks. She is always trying to get CeCe out of trouble, which often gets them both into trouble. Rocky loves dancing and wants to pursue it, much to the early disapproval from her father ("Doctor It Up").
In season 1, Rocky is very outspoken and expresses herself in quiet and respectful ways (excluding "Wild It Up"), but in season 2, it seems that more of her assertive and snarky side comes out. For example, in "Split It Up", she was breaking cups with Tinka, and in "Weird It Up", she warns CeCe saying, "CeCe, if you don't apologize, you're gonna have to deal with my super-bad-wheel-of-punishments!"
