D'Artagnan is initially portrayed by Dumas as a hotheaded youth, who tries to engage the Comte de Rochefort and the Three Musketeers, Athos, Porthos, and Aramis in single combat. He quickly becomes friends with the musketeers, and has a series of adventures which put him at odds with Cardinal Richelieu, then First Minister of France. In the end, Richelieu is impressed by d'Artagnan, and makes him a lieutenant of the musketeers. This begins his long career of military service, as detailed in the sequels.

D'Artagnan's role among the musketeers is one of leadership (his skills and brains impress the musketeers greatly), but he is also regarded as a sort of protégé given his youth and inexperience. Athos sees him not only as a best friend and fellow musketeer but nearly as a son. At the end of the series, his death at the siege of Maastricht is given an extra tragic twist – he is mortally wounded while reading the notice of his promotion to the highest military rank.

*The real Charles de Batz de Castelmore was used as the basis for Gatien de Courtilz de Sandras' novel Les mémoires de M. d'Artagnan. Alexandre Dumas in turn used Sandras' novel as the main source for his d'Artagnan Romances.
*D'Artagnan met Cyrano de Bergerac, they were rivals and friends in works by authors such as Paul Féval and H. Bedford Jones.
Although Fairbanks was primarily known as a comedic actor early in his career and is often said to have fully moved into the adventure genre with ''The Mark of Zorro'' (1920), ''A Modern Musketeer'' (1917) can be regarded as a prototype of his later swashbuckling persona, with his role as Ned Tracker, a modern reincarnation of d’Artagnan, anticipating many of the traits he would refine in his subsequent adventure films.
