A little profile:

Name: Aurora Lin Neige
Age: 15
Occupation: Illegal Hero - Vigilante

Superpower: Aurora can crystallize the air making direct contact with her skin, forming snow, ice, sleet and hail. This primarily serves as a defensive option, since any air not touching her skin is not subject to her freezing. She fights with two spiked icicle maul encasings on either fist, and dons a entire suit of packed snow and blue ice, making her nigh indestructible. Unfortunately, she is not immune to cold: Prolongued usage of her abilities will lead to hypothermia, frostbite and eventually death. She needs to warm up between battles, and excels in outlasting her opponent before retreating.

A timeless maiden with coal pitch eyes and a button nose, Aurora can often be found fiddling with a worn corncob pipe in dark alleyways or on the tops of shady buildings. No one really knows anything about her, but years of experience and countless victories speak for themselves.
