Frosta is a valuable member of the Rebellion. She is the reigning Queen of Castle Chill in the Kingdom of Snows, an area located at the northernmost pole of Etheria.
Frosta is able to lower her external and internal body temperature without harm to herself, thereby radiating intense cold from her body, most often as laser-like beams from her hands. Frosta is able to reach -105 degrees Fahrenheit within a few seconds, and is immune to sub-zero temperatures around her. In addition, she can freeze any moisture in the air around her into unusually hard ice, and thereby form simple objects such as slides, ladders, and shields.
She can also freeze objects enough they will shatter when touched or simply localize a small area with snow. She also develops a crush on He-Man, who seems sometimes embarrassed due to her flirtatious behaviour.
