His body is a dark gray human-like figure, with long pale gray-white hair that covers most of his face. A small amount of his hair is pulled into a ponytail held with a dark blue band. He has a single visible red eye as his iris, with the sclera being black. He wears a blue outfit with a dark blue material around the waist held with a goldenrod band. The lower leg is covered by dark blue stockings to match his fingerless gloves, while the sandals are black. Around his neck is a scarf of black, with the tails resembling dragon heads.
In a dream, it seems that Shadow Venoct likes very dark places, almost mirroring Hidabat in the real world; so much that when Whisper opened the closet he was in, he threatened the butler Yo-kai with his scarf.
Shadow Venoct is Venoct's shadow. Presumably, being Venoct's shadow, Shadow Venoct has the same abilities Venoct has. Unusually, however, Shadow Venoct shows a penchant for healing.
According to Recap Time, Shadow Venoct can make people disappear from the world if they look at him.
