Cutie_nightmare is a Scottish VTuber who is a guy with a female avatar trying to spread smiles to their audience.
A real nightmare come to life. Since they are a nightmare they can change their form at will, but they do have a true form. They rarely show it and no one really know why they take the form they do, but they have taken it and seem to refuse to use their power as a living nightmare. This makes them an outcast in their race but they don't care as they're going to make their own family.
