Technically a "prophet" of the season guardians, she's seen for her innocent and sweet nature. Ever since her transformation however, she's reverted to a more neutral form to act as a balance between both positive and negative emotions. It's not too big a struggle, but it still takes a good bit of self control to keep herself in line.
P.S. I've decided to call her nightmare form "Fever Dream". Kinda like Shattered Dream, but I changed it
