Mapleshade is a large, thick-furred, Calito/Tortoiseshell/white Maine Coon mixed she-cat with amber eyes, orange coat with black spots, and a long, thick, fluffy, white tail.

Mapleshade is temperamental, selfish, cold, vicious, ruthless, manipulative, and obsessively vengeful, her psyche distorting to the point of insanity due to her past trauma of being exiled from Thunderclan, loss of her kits, rejection from Riverclan, vow of revenge even after achieving it.
