Lady Marguerite Blakeney
- Ascended Fangirl: Fangirl-ing over The Scarlet Pimpernel, later realises she married him and joins his adventures.
- The Atoner: The second half of the book is all about how she feels she must atone for betraying her husband.
- Determinator: Follows Chauvelin's cart, barefoot, for miles.
- Informed Attractiveness: Marguerite is immensely beautiful — she's the most beautiful woman in any room and she's basically the hottest redhead there ever was or will be.
"There are many portraits and miniatures extant of Marguerite St. Just Lady Blakeney as she was then but it is doubtful if any of these really do her singular beauty justice. Tall, above the average, with magnificent presence and regal figure. (...) Marguerite Blakeney was then scarcely five-and-twenty, and her beauty was at its most dazzling stage. The large hat, with its undulating and waving plumes, threw a soft shadow across the classic brow with the aureole of auburn hair free at the moment from any powder; the sweet, almost childlike mouth, the straight chiselled nose, round chin, and delicate throat, all seemed set off by the picturesque costume of the period."
- Loves My Alter Ego: To her husband. Loves the Alter Ego while belittling his Rich Idiot with No Day Job persona. Played with a bit, since it's suggested that deep down she genuinely does love her husband and is deeply hurt by the fact that he doesn't appear to reciprocate after she confessed her role in the deaths of the Marquis de St. Cyr and his family, causing her to lash out.
- Ojou: A very classy and fashionable young lady of great repute.
- Sadistic Choice: Her brother will be executed or she will find her idol and put him in her brother's place in the hangman's noose.
Sir Percy Blakeney (The Scarlet Pimpernel)
- Agent Peacock: He dresses to outshine the girls, appears late at balls because he lost his time trying to tie his cravat just right, and generally dismissed as a fop. Has snagged the hottest redhead in Europe as his wife, and all the ladies fawn over him, his Camp posturing, and his slender white hands that are dainty enough to pass as a woman's. Also happens to be the ultra-badass secret vigilante who pulls off daring rescues of French aristocrats on a regular, if not daily, basis.
- Batman Gambit: Pulls these on Chauvelin at least once a book.
- Dating Catwoman: Essentially married Selina Kyle before she revealed she was Catwoman.
- Deadpan Snarker: Usually at Chauvelin's expense.
- Dogged Nice Guy: Towards his wife, more so in their Back Story.
- Famed In-Story: Scarlet Pimpernel is a legendary figure in contemporary France and Britain. Sir Percy is rather famous as well — as a member of British aristocracy.
- The Gadfly: Has his moments, such as when he pulls a pepper prank on Chauvelin, or a Stealth Hi/Bye. Also the time when he wrote and recited his own theme poem.
- Genius Bruiser: It's often commented on that he's a very tall, well-built man, and the intelligence goes without saying.
- Heroes Want Redheads: His wife Marguerite has red hair.
- Hidden Depths: He acts foppish, but he's skilled in combats and he's extremely fit.
- Master Actor: Percy is able to pass as a soldier, (female) merchant, Gentle Giant, or just about anything else.
- Master of Disguise: It's how he is able to save everyone.
- Nerves of Steel: He can hold his nerves and he stays calm even when he's in danger of being discovered.
- Non-Idle Rich: He plays Idle Rich, but he's actually an aristocrat who does important and heroic things.
Sir Andrew Ffoulkes
- Blackmail: How he forces Marguerite to act against her idol, Scarlet Pimpernel.
- Defector from Decadence: As he would see it, having renounced his title of Marquis and joined the revolutionaries.
- It's Personal: His repeated failures to capture the Pimpernel mean that his power and influence steadily decrease through the series. This leads him to become increasingly obsessed with getting revenge on the Pimpernel.
- Sadistic Choice: His specialty — "either...or"
- Smug Snake: He's not without cunning, but he's frequently described as a rather weaselly, sneering sort with an almost permanent sarcastic expression and manner.
Leader of post-Revolution French government which is self-dubbed as Reign of Terror.
- Sweet Polly Oliver: When posing as a refugee, she arrives in Dover disguised as a soldier.
