Robinwing is a calico cat with blue eyes. Her fur is medium-long. Her name derives from the colours of her pelt, but also her territorial nature. Robinwing is the sister of Sootpelt. 

Robinwing and Sootpelt were very mischievous as kits and would often get into trouble. One time, Sootpelt had found a badgers set and was injured. Though his injury was not serious, Robinwing took this as a sign that they needed to become more serious in their training and loyalty to their clan. It is not unusual to see her scolding him for 'acting like a kit'. 

Robinwing is fiercely loyal to Windclan and will not hesitate to jump into a fight if needed. She is an excellent fighter, being agile as well as strong. Her dream is to become deputy, and then leader of her clan.

Also her personality can be harsh and abrasive, she does care deeply about her brother and clan. She does not get along well with cats of other clans, and dislikes Sunsong because of her friendly attitude towards them. Robinwing does not trust another cat easily and treads warily.
