!! The show as a whole has:
* EarWorm: The theme song, in all its incarnations.
* FanonDiscontinuity: It's rare, but there are some fans who disregard ''The Black Adder'' due to how out of step it is with the following incarnations. A slightly more common viewpoint is that the Blackadder lineage died with Captain Blackadder at the end of ''Blackadder Goes Forth'', and that ''Blackadder Back & Forth'' never happened.
* GrowingTheBeard: Many fans prefer the seasons after the ReTool. The first season has its laughs, but it's just not as much fun watching a screwball doofus and his two moron friends as it is watching a wicked snarker and his two moron friends. However, if nothing else, the first season would still be required watching purely on the strength of [[BrianBlessed BRIAN BLESSED]]'s ''definitively'' hammy performance (in fact, it's the source of the current image and caption on his page).
** Incidentally, Blackadder gains a literal beard in the second season, the first one after said ReTool.
* NauseaFuel: Occasional. Usually provided by Baldrick.
* SeasonalRot: Inverted for the most part. ''The Black Adder'' is generally felt to be pretty average, ''Blackadder II'' awesome, ''Blackadder the Third'' a slight step down from the previous series but still very good, and ''Blackadder Goes Forth'' the best of all.

!! ''The Black Adder'' has:
* CrazyAwesome: King Richard IV. Goes to war just for the hell of it and is implied to have killed several ''thousand'' Turks with a fruit knife.
* CrowningMusicOfAwesome: [[http://www.youtube.com/watch?v=a3F37kQl9Uw&feature=related The ending theme ]]
* EnsembleDarkhorse: [[BrianBlessed King Richard IV]], due to his [[LargeHam characteristically over the top performance]].
* FanNickname: The nameless King played by John Savident in the original, unaired pilot has been nicknamed King Frederick I by fans, in reference to Savident's [[Series/CoronationStreet most well-known role]].
* IAmNotShazam: Inverted. Other characters rarely call Prince Edmund "Blackadder".
* WhatAnIdiot: [[spoiler:Edmund, in the final episode, samples the wine ''even after seeing everyone else in court drop instantly dead from it''.]]
** Well, that, or he [[spoiler: [[DownerEnding commits suicide]]]].

!! ''Blackadder II'' has:
* BigLippedAlligatorMoment: The scene in "Bells" where Blackadder falls in love with "Bob", which suddenly turns into a love song album commercial, for no discernible reason.
** Well, I can think of [[RuleOfFunny one.]]
* EvilIsSexy: Lord Blackadder.
* FridgeBrilliance: Prince Ludwig permanently impersonating Queen Elizabeth nicely explains the whole virgin queen thing.
** Also, Prince Ludwig is very likely an ancestor of Prince George (George IV) from Blackadder the third. George IV's great grandfather was Georg Ludwig of Germany. Which explains the uncanny resemblance (both are played by Hugh Laurie)
* GrowingTheBeard: According to popular opinion, this is the season where it happened.
** Quite literally. The original Black Adder is beardless, while the Elizabethan version is bearded, as well as more interesting, although Blackadders of the third and fourth installments are also beardless.
* MemeticSexGod: Lord Flashheart.
** Lord Blackadder has a beard, wears a ruff and a codpiece, yet in spite of this, he's consistently considered the sexiest incarnation of the character by the fandom... [[EvenTheGuysWantHim even the men]].
* NightmareFuel: TheStinger to the "Chains" episode probably qualifies.
** After the credits, [[spoiler:we hear a [[ForDoomTheBellTolls tolling bell]] and eerie wind noises (from the intro to EltonJohn's "Funeral for a Friend") as the camera pans over the murdered, wide-eyed bodies of Edmund, Percy, Queenie, Nursie, Baldrick, and Melchett. We then see Queenie there, alive and well, before she turns to the camera, gives a chuckle in a strange voice and says, in the master of disguise Prince Ludwig's voice, "Now this is a disguise I'm really going to enjoy. If I could just get the voice right." A CREEPY end to the season.]]
* OneSceneWonder: The fandom loves Lord Flashheart. So does the balladeer:
-->"Lord Flashheart, Lord Flashheart\\
I wish you were the star\\
Lord Flashheart, Lord Flashheart,\\
You're sexier by far."
* TheWoobie: Lord Percy Percy. Despite being constantly insulted by Lord Blackadder, he would do anything for him and sees his insults as nothing more than his friend being witty.

!! ''Blackadder the Third'' has:
* AcceptableTargets:
** Nothing like repeatedly insulting the French.
** And the Welsh. Really, this season is quite merciless.
** Ditto Germans.
** Politicians too:
-->'''Blackadder''': Criminal record?
-->'''Baldrick''': Absolutely not.
-->'''Blackadder''': Oh, come on, Baldrick, you're going to be an MP, for God's sake!
** [[HypocriticalHumor And actors]]:
-->'''Blackadder''': You mean they actually rehearse? I thought they just got drunk, stuck on a silly hat and trusted to luck.
** Judges too:
-->'''Blackadder''': Well, you could appoint him a high court judge.
-->'''George''': Is he qualified?
-->'''Blackadder''': He's a violent, bigoted, mindless old fool.
-->'''George''': Sounds a bit overqualified!
** Anyone else who isn't Edmund Blackadder.
* CargoShip: Lord Sod-off Baldrick has a relationship with his turnip.
* CrowningMomentOfFunny: Blackadder in "Dual and Duality": "A man may fight for many things: his country, his principles, his friends, the glistening tear on the cheek of a golden child... But personally, I'd mud-wrestle my own ''mother'' for a ton of cash, an amusing clock and a sack of French porn."
* HilariousInHindsight: The ending of "Nob and Nobility" has Baldrick elevated to being a lord over Blackadder, much to the latter's annoyance. In 2013, Baldrick's actor Tony Robinson was knighted, while Rowan Atkinson "only" got a CBE.
* LawfulEvil: Although Edmund claims that his only loyalty is towards himself and that he is incredibly ruthless and cold, only the latter is completely true as he demonstrates a great deal of loyalty for his boss, despite the fact that his boss is incredibly stupid and that he (Blackadder) could manipulate him into giving up all of his (The Prince) money and power to him. [[spoiler:He even risks his own life for him. But abandons The Prince after he is mortally wounded.]] Making him a Type III Lawful Evil character.
* MagnificentBastard: This series's Blackadder is a prime example, certainly the most outright evil and manipulative of the dynasty. The only one who [[spoiler:not only [[KarmaHoudini doesn't die at the end of his series]], but actually achieves his goals.]] The one in ''Blackadder: Back & Forth'' does too, admittedly, but he had a time machine - ''Blackadder the Third'''s Blackadder did it with just his cunning and wit.

!! ''Blackadder Goes Forth'' has:
* AwesomeEgo: Lord Flashheart could potentially be the poster boy of this trope.
* CrazyAwesome: Lord Flashheart, more so than his Elizabethan FakeUltimateHero incarnation.
* EnsembleDarkhorse: Lord Flashheart. His role is greatly expanded from his previous incarnation's, but he still only appears in one episode.
* HarsherInHindsight: Blackadder flirting with Nurse Mary.
-->'''Blackadder''': Yes, why not? When this madness is finished, perhaps we could go cycling together. Take a trip to the Old Swan at Henley and go for a walk in the woods.
** Given that nowadays there's a heightened awareness of hate crimes, Flash shooting the Red Baron in cold blood and then yelling a homophobic insult at his corpse is pretty awkward to watch. Not that it wasn't in character.
** The line "Cancel the state funeral, tell the King to stop blubbing, Flash is NOT DEAD!" may be a bit more difficult to laugh at now that Rik Mayall, who played Lord Flashheart, has passed away.
* HoYay: "Baldrick, I love you. I want to kiss your cherry lips and nibble at your shell-like ears."
* JerkassWoobie: Captains Blackadder and Darling.
* MoralEventHorizon: Comedy or not, by the end you are not going to like [[TheNeidermeyer General Melchett]].
* OlderThanTheyThink: Much of the anti-war themes, tropes, and character archetypes relating to UsefulNotes/WorldWarI (or the Great War, if you prefer) are present in the British war comic series written by Pat Mills and drawn by Joe Colquhoun, "Charley's War."
* TearJerker: Highly unusual for a comedy series, but the last episode of ''Blackadder Goes Forth'' cannot fail to bring tears to anyone's eyes.
** It aired on Remembrance Sunday with no complaints. Such is its power.
** It's made all the more heartrending in the audio only version, where, since you can't see them, you have to imagine them going over the top, and as the sad reprise of the main theme is happening, you can hear a line each uttered by a character earlier in the episode; George: "We've had some good times, we've had some damn lovely good laughs.", Baldrick: "I thought it was going to be such fun, too.", Darling: "But sir, I don't want to...", and Blackadder himself: "Good luck, everyone...".

!! ''The Specials'' has:
* FamilyUnfriendlyAesop: It's played for laughs, but let be honest. ''Blackadder Christmas Carol'' shows how easily altruists can get [[BeingGoodSucks exploited by freeloaders]].
* {{Squick}}: The visions in ''Christmas Carol'' shows at one point Baldrick in a speedo.
--> '''Blackadder:''' And I end up wearing Baldrick's posing pouch.
