Kayla was the past princess of the jungle many years ago. The jungle was past the wastelands. (Like in The Lion King movie) Where Timon and Pumbaa took Simba to the place.
Kayla had a similar design to Vitani, but she has a different personality and colors. She was full of hate. She has a few relatives. The Hyenas became her army to kill Mohatu and her sister Angelica.
Her parents died and now she has dificulties with her sister. She has an outsider nose like her sister.
