Cold Stress

Cold Stress (called "Ness Cossette by Mia), also Cold Shock, is the butler and messenger of Frostbite and Hypothermia. Cold Stress is sent by Mia to warn people who were exposed to cold. People usually avoid them. Cold Stress possesses both freezing and mind-body control powers but not as strong as Frostbite and Hypothermia's. They represent both cold stress (the pre-hypothermia stage) and cold shock. As Cold Shock, they also can kill humans.

Cold Stress is not considered as a physical entity because they switch between 2 genders as a reflection. They have a weak shapeshifting power.

Physical form
Cold Stress' physical form is male with black hair. In this form, he has light coloured skin and blue eyes. His hair length is below ears and has very short cut fringe. He wears a black stereotypical butler suit.

Reflections
Cold Stress has 2 different reflections and can switch between two.

Male reflection
The male reflection looks just like their physical appearance but much more fancy-looking with jewellery and has white-purple hair. He wears a white suit instead of black in the physical form.

Female reflection
The female reflection resembles Frostbite's appearance.
