Robb inherited much of his appearance from his mother's side of the family - blue eyes, auburn hair, and a stocky build.At the beginning of the story, Robb is 14 years old.

As the son of Eddard Stark, he inherited his father's character: honor, loyalty, and justice.

Robb possesses all the qualities a young commander needs.

He acts as a pioneer in the war without flinching, and has the courage to shoulder responsibilities. He can deceive the wily Tywin and catch James, the murderer who hurt his brother. He can also manage a group of subordinates who are older than himself and rely on their experience..

He has a group of loyal followers in the north, and the Tully family, which occupies the strategic route south, is his mother's natal family.
