Nicholas Nickleby is the titular character of the novel and its central protagonist. Handsome and approachable, Nicholas strikes others as “gentlemanly” due to his manners even after his family falls on hard times. He is most characterized by his valiant ethical code: In the face of adversity, Nicholas always chooses the side of justice. However, Nicholas is barely an adult when the novel begins and initially follows his uncle’s lead, accepting a job at Dotheboys despite his qualms. As the story progresses, Nicholas takes more control over his life and proves himself to be the hero of the story on several occasions—whipping Mr. Squeers for beating Smike, leaving his theater job to save his sister from public humiliation, etc. By beating up Kate’s primary harasser, Sir Mulberry Hawk, Nicholas also recognizes The Importance of Family.

The story rewards Nicholas for his heroism and hard work, suggesting that Justice Will Prevail. His fortunes begin to change when Charles Cheeryble hires him and sets his family up in a rented cottage. The income makes Nicholas the official head of his household, safeguarding his mother and sister from the manipulations of the corrupt Ralph Nickleby.
