Vee is a basilisk beast demon that has a small, chubby serpentine body with two arms and a fishlike tail in place of legs. Her face is round with wide eyes and a turned-up nose. She has a catlike mouth in a "W" shape with two small teeth poking out from her bottom jaw with her lower lip being a dark maroon color. She has pale, swamp-green scales with cream-colored spots on her head, tail, underbelly, and the bottom half of her face. There are tufts of navy-blue hair on her head, back, and ears. Her eyes consist of yellow-gold pupils, black irises, and aqua sclera. She has off-white fins on the sides and tip of her tail, along with a dull peacock-blue piercing on the tip. She is 5'6". Later on, Vee changes her human form's appearance to differentiate herself from Luz; her hair is green with blue tips, resembling her fins, and she keeps her basilisk ears which blend into her hair. Her skin color is lighter, though still similar enough to easily pass as a member of the Noceda family, and her legs have more muscle mass. She also retains her basilisk eyes, but the sclera is now white. Vee is a good-natured individual, albeit rather insecure about her identity as a basilisk. Due to her past, where her only purpose was to be a test subject for one of Belos' experiments, Vee was troubled about her existence, and being a creature that should no longer exist, she yearned to find a better life with an identity to call her own. When she started living with Camila, she became more comfortable after shapeshifting into an impostor of Luz, easily deceiving her and others into thinking she was the real Luz for months. As the impostor, Vee is shown to be laid-back, opportunistic, and more toned down compared to the real Luz. Despite the deception, Vee did not favor subterfuge, as she did not wish to trick Camila and only did so to pay back Camila's kindness rather than taking advantage of it. She is fearful and timid of strangers and dislikes confrontation heavily. When put under pressure or in troublesome situations, Vee can be left petrified for an extended period of time. By the time Luz returned to the Human Realm, Vee had adjusted well into human culture, giving her the most common sense out of Luz's friends. She also gained a boost in self-confidence, for she was willing to confront Jacob Hopkins again, despite initial trepidation from when he imprisoned her before and even stood against Belos himself while he was possessing Hunter. However, she is still wary of humans finding out about her true nature.
