Glacia

Glacia is an Ice-type Pokémon introduced in Generation IV.

Glaceon is a quadrupedal, mammalian Pokémon covered in light-blue fur that can be frozen into sharp quills. It has long, pointed ears, dark eyes, and a small nose. A teal crest with two dangling flaps adorns its head, resembling hair or headgear. Glaceon has two dark blue, rhombus-shaped markings on its back; the tip of its tail, feet, and flaps are the same shade of blue.
By controlling its body temperature, the moisture in the air freezes, producing ice crystals surrounding it. It is capable of freezing its fur into sharp needle-like icicles, used to tackle its prey. It can drop its body temperature below -75 degrees Fahrenheit. Those captivated by Glaceon's beautiful snowfall will be instantly frozen without realizing it. Glaceon is rather popular in ski resorts due to its ability to create powdery snow. Glaceon is usually found in urban areas under the care of humans. It is rarely found in the wild.
