As a powerful ice sorceress, Frosta is the Queen of Castle Chill, which resides in the Kingdom of Snows. She amazing powers as a member of The Great Rebellion and had the ability to control ice and snow at will. This allowed her to freeze objects or foes and use ice as a means of transportation. She can do this by lowering her body temperature and is immune to sub-zero temperatures. She can also freeze moisture to her advantage to create simple objects, shields, and ladders. 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 appeared in several episodes of the She-Ra Princess of Power cartoon:

• Duel at Devlan
• Enchanted Castle
• Three Courageous Hearts
• Into the Dark Dimension
• Loo-Kee Lends a Hand
• Black Snow
• Day of the Flowers
• He-Man and She-Ra: A Christmas Special (cameo)
