- Anti-Climax Boss: Roger de Carnac's name strikes terror into the hearts of Gisburne and the Sheriff, his methods are as brutal as they are cunning, and he's played with a creepy detached air by Matthew Frewer. Robin kills him before the episode's half-way mark.
- Complete Monster: Morgwyn of Ravenscar from the two-parter The Swords of Wayland is a powerful witch and leader of the Cauldron of Lucifer coven. To set about gathering the Swords of Wayland to summon Lucifer from hell, Morgwyn kidnaps villagers and brainwashes them into an elite troop known as the Hounds. She sends the Hounds to kill and be killed by their own people and bring her the swords. One young man fails to recognize his own parents and kills himself upon being captured. Morgwyn kidnaps the outlaws and attempts to Mind Rape them into killing Robin himself. Finally, Morgwyn plans on sacrificing them in a ceremony to summon her dark master Lucifer himself to cause the Apocalypse and consume the world.
- Crowning Moment of Awesome: Robin of Loxley - in his final moments, he bravely faces down a small army of Norman warriors and fires an arrow over their heads. When he draws his bow a final time — without an arrow — they cringe away. He then looks knowingly at the Sheriff and smiles without fear, breaks his bow over his knee, and turns to face his death.
- Crowning Moment of Funny: Robert de Rainault calmly reading out the transcript of a woman's brutal interrogation by torture in a bored-sounding voice.
- Depraved Homosexual: Arguably Philip Mark, for his casual brutality as well as several implications of pederasty (including his boy-servants clad in finery while the girls remain in rags, his flirtatious chin-chucking of one of the boys, and de Rainault calling Mark himself a "posturing catamite").
- Ensemble Darkhorse: The old man in Nottingham Castle dungeons, along with his rat Arthur.
- Fandom Heresy: It's not a good idea to state that you thought Jason Connery was a better Robin Hood than Michael Praed.
- Ho Yay: Guy and the Sheriff. In one episode, Guy is made to towel-dry the Sheriff, who orders, "Harder, Gisburne!"; later they share a bathtub, where the Sheriff tells Gisburne, "Rub my back! Lower!" A few episodes later, when the angry Prince John punishes Gisburne, he addresses him as "de Rainault's protégé - if that's all you are"; Guy responds by uncomfortably looking away.
- Narm: Plenty of times, usually to do with Fight Scene Failure or the Soundtrack Dissonance. Due to the Nostalgia Filter, it may now count as Narm Charm.
Much: Gisburne killed Father!Robin: GISBUUUUUURNE! (echoes several times)
- From the first episode:
Gisburne: I'm free of you, Sheriff. I'm free of you! (runs to the window and shouts) I'M FREE OF YOU NOOOOOOOOW!!! (echoes several times)
- From "The Enchantment":
- One-Scene Wonder: Queen Hadwisa and Queen Isabella of Angoulême.
- Special Effects Failure: The fact that the Silver Arrow in The Pilot looks like a small cruise missile and/or vibrator has often been remarked upon by the show's fanbase and even the show's creator.
- Throw It In: De Rainault's assessment of Philip Mark as a "posturing catamite" was supposedly an ad lib.
- The Untwist: In one episode Nasir is being hunted by a Saracen called Sarak. Because his face is covered, and he speaks in a growly voice, there is some indication that it is actually the woman that was with Sarak when he and Nasir fought the first time. Except...it's not.
