Nettlescar is a dark brown tabby she cat with a lighter belly, ice blue eyes, her left eye blind, with a scar on it, and a long scar starting at her shoulder and slinking down to her underbelly.
Nettlescar is first seen telling Viperpaw to help herself take over all the clans, and to kill Mistshade. Mistshade hears the plan, and runs off to tell her mate, Hailstar. Nettlescar gets Mistshade, and Viperpaw gets Hailstar. There is a fierce battle until, it seems like Mistshade is dead, and Hailstar is defeated.
