Ruby Mae "Gradient" Huggins Ortiz is a member of the Wuzzlewood singing group, the Wubb Girlz. She is a dancer for the band.
Gradient has light blue skin, her hair is shoulder-length and is colored ombre blonde-pink. She commonly wears the Wubb Girlz attire which consists of a pink shortsleeved shirt with a purple belt around the waist, which reveals a pink skirt at the bottom. She also wears purple leggings, which reveal only a little bit of her legs before ending in pink high-heeled boots. On her boots and shirt are diamonds.
Gradient was once shy, and had a hard time opening up. Being a member of the Wubb Girlz eventually helped her loosen up and just be herself. She is now happy-go-lucky, but can be easily intimidated in unfamiliar situations.
