Ice

Seriously. That's her name, Ice. She has the power of ice, she can blow ice breath and ice shards from her mouth, she lives in temperatures between -50°F to 10°F, and she can form an Arctic Blizzard. Her pet is an ice bengal tiger (white with dark blue stripes). She lives in an ice palace, decarated with sharp icicles, ice sculptures, and shiny glowing crystals. It's always below zero in her palace, and she lives alone. She's amune to freezing temperatures and cold things, and she hates the summer season.
