Kemmy's appearance resembles that of a chameleon. She has dark yellow skin with purple stripes on her body and white spikes. Her eyes are black. There is a big light purple, diamond-shaped spike decorated by two small diamonds in a lighter shade of purple on her forehead.
Kemmy, Frostbite, and Occula were called forth from the Legendarium World by Brafilius, who had acquired the Ultimate Power of the Fairy Animals and wanted an army of the strongest Fairy Animals across all the dimensions. This led to the Trix being released from the Legendarium World, as Kemmy had bonded with Darcy, Frostbite bonded with Icy, and Occula bonded with Stormy.
Like Darcy, Kemmy can create illusions. Coming soon...
- She is one of the "most powerful Fairy Animals in the entire Magic Universe and beyond", because when Brafilius invokes the Fairy Animals with that criteria, she appears.
