Hypothermia

Hypothermia, also known as Mia (from her name's last three letters), is the personification of hypothermia. Mia is responsible for lowering people's body temperatures. Hyperthermia is the opposite of Hypothermia; besides of being opposites they have a good relationship.

She can appear as a physical person or as a hallucination to hypothermic victims.

.Mia appears to her victims as a ghostlike being. This way, she's considered as a "semi-physical humanoid entity". Hypothermia does not mimic humans, her real form is humanlike. Some people say that her human alikeness is only at outside; she might be totally different from humans in inside. One of the most known difference of Mia is that her being a poikilotherm. In her physical form, Mia has bluish pale skin, purple to blue eyes, dyed white hair. Mia's natural hair colour is a very dark black that has a bluish glow. She has a grey piercing in her left eyebrow. Mia wears black eye makeup which she makes it look like flowing down. Mia's lips have a very pale blue tone, Mia paints her upper lip black and lower lip purple with some "mysterious" lipstick. Hypothermia sometimes wears black and purple locks in her hair. The hair for locks were obtained from her now-dead victims.

Not much about Mia's physiology is known. Many people think that she has a constant body temperature that is lower than water's freezing point. The reason why she has such a low body temperature is that she lives in cold weather. Unlike humans, Mia's body temperature is not constant. She's poikilothermic, which means that her body temperature changes with outside. Due to lack of inability of breeding in her "species"[1], Mia is eventually asexual. Mia's voice got deeper over time, she had being shouting a lot in wars and this has damaged her voice. People who had encountered with Mia before 19th century described her voice as "angelic" or "divine", now she sounds like a man imitating a woman's voice according to modern encounter reports.

Hypothermia has a tendency to scare people, especially very young, very old or sick ones who are in cold. She does this to protect them and to tell them to go back to warmth, not to harm them. Mia has such protective behaviours, she does not like to harm. After she freezes them, she gives them another chance to be rescued. Mia silently and painlessly kills her victims.
