* One of the running themes of the show is that DarkIsNotEvil. Darkwing being the prime example, but Morgana is also a "night person". It never occurred to me how much they wanted to drive that theme home until I realized Megavolt is the other half of the analogy: one of the most dangerous criminals in St. Canard is [[LightIsNotGood constantly surrounded by light]].
** And Negaduck's costume is bright yellow and red. His cape is black, but it's lined with bright red.
* The [[Creator/AynRand Objectivist]] themes surrounding [[Creator/CarlBarks Scrooge McDuck]] spilled over into [[WesternAnimation/DuckTales his show's]] SpiritualSuccessor - it's all about a protagonist with "an ego the size of a small planet" whose motive power is not altruism but personal pride and a pathological need for action.
** Also a strong theme with Gosalyn: in addition to sharing her adopted father's massive ego, she's got quite the beak for money; in several episodes, she tries to cash in on whatever the current situation is, whether by hawking "official" merchandise to Darkwing's fan club, or discreetly trying to scoop up the bribe money Darkwing just refused to take from Bushroot. She's not very altruistic, but she does have an admirable profit motive.
* When this troper discovered that Magica Despell was going to be a antagonist in the 2011 comic book this just hit him... throughout her appearances in comic and animation history, she not only targeted Scrooge but Donald, Daisy, the Nephews, even Gizmoduck. But there was one Duck protagonist she NEVER antagonized at the time... DARKWING! now that she fought Darkwing then that should be crossed off the list.
* Launchpad is a much better pilot in this series and doesn't [[CaptainCrash crash-land]] nearly as often as he did in ''WesternAnimation/DuckTales''. However, if you recall the last episode of ''[=DuckTales=]'', "The Golden Goose," he managed to make a perfect landing while attempting to crash on purpose. It would appear that by the time ''Darkwing Duck'' began, Launchpad's finally learned how to land.
* Take the [[ItRunsOnNonsenseoleum hilariously absurd concept]] of everything in Darkwing's universe being made up of "posi-trons" and "nega-trons" as seen in the episode "Negaduck" and you come to realize that even if [=NegaDuck=] is not exactly the same character as the Negaduck from that episode, of course he would act nearly the same: the properly integrated Darkwing Duck a good guy, so he has more posi-trons than nega-trons. In the Negaverse, the ratio of posi-trons and nega-trons in every single inhabitant is flipped, and therefore all of the nasty traits we see in Negaduck are predominant in [=NegaDuck=] as well.
** Gosalyn and Nega-Gosalyn also present another interesting aspect of this cosmology: while the ratio of posi-trons to nega-trons determines a lot of your behavior, it doesn't necessarily determine your morality. Prime Gosalyn actually has slightly more nega-trons than posi-trons, which is why she's such a BrattyHalfPint, whereas Nega-Gosalyn has the exact opposite ratio, which is why she's such a well-mannered GirlyGirl. Both are good girls because it's possible to turn both positive and negative traits to good purposes, in keeping with the LightIsNotGood and DarkIsNotEvil lesson this cartoon is teaching us.
* The reason why Drake Mallard's money tree had withered and died in "Easy Come, Easy Grow" by the time the police came around to arrest him for counterfeiting? [[GeniusBonus As Bushroot and any other competent gardener or farmer]] could tell you, too much fertilizer at a time can be deadly to plants; and he dumped a ''whole bag'' of it on that poor tree!
* One of the greatest problem in superheroes stories is WhyDontYaJustShootHim, but the very first episode of the show justifies why: Darkwing is shot many times, while distracted, and once even point-blank for good measure, and he just easily dodges each of them. It showed that nothing that simple would actually work, and much over-the-top schemes would have been necessary to deal with him.
* [[WholeEpisodeFlashback By narrating the plot of "Night of the Living Spud"]] to a group of Boy Scouts (or are they [[WesternAnimation/DuckTales Junior Woodchucks]]?), Darkwing revealed his SecretIdentity as Drake Mallard, didn't he? Actually, no -- at no point in Darkwing's story do we see Drake Mallard changing into Darkwing Duck. In the story as told, Drake's merely the neighbor of the Muddlefoots, who sees them leave to go camping (establishing why they're there when the monster catches them), and then sees the strange news report that segues into Bushroot's latest crime spree and Darkwing Duck first getting involved. After that, he's never seen again, nor does Gosalyn ever address him as "Dad." In Darkwing's version, Drake is merely an innocent bystander used to provide exposition via what he observes, not an important character like Darkwing, and an in-universe listener who knew nothing about either of them would never make the connection.
* In one episode it's mentioned that they've tried and failed to give Megavolt the chair. This is just meant to be a little joke, but in order for him to get the chair wouldn't he have had to commit murder?
** Considering how this show has no qualms about directly referencing death, that was probably intentional.
** Treason is also punishable by death, so maybe Megavolt was a double agent for an enemy government.
*** There are some implications that the justice system in that universe [[DeadBabyComedy applies the chair willy nilly]].
** Another example: in one episode, it's revealed that a certain video game's main character is created by having a person actually teleported into the game. Of course, later in that episode, Darkwing is accidentally teleported in, and promptly discovers that even if it is a game, he can be injured and feel pain. What does the poor main character go through whenever the player loses?
* "Extinct Possibility": Darkwing is encased in amber after being sent to the age of Dinosaurs, encased with his ''eyes wide [[AndIMustScream open]]''.
** Worse, the dinosaurs often mention [[HumansByAnyOtherName hairy ape creatures]] taking the first steps in evolution. They often brag about how they [[FinalSolution "put a stop to that nonsense"]].
* Splatter Phoenix has the ability to bring paintings to life. When she dies, she melts like the other paintings. Maybe this isn't the real Splatter Phoenix, and the original was actually murdered by the painting of herself and she took her place.
* Whatever Bud Flood was putting in his competitors' water supplies was also what made him the Liquidator. Drinking that GrimyWater he was making might've had far worse consequences than just getting a bad taste.
* The fact that Negaduck is the guardian of his universe's Gosalyn. In-universe as well, just ''considering'' that idea was more than enough to convince Darkwing to stay and free that world. It's honestly Fridge Horror imagining what Darkwing was thinking!
* If Paddywhack did pull Gosalyn into his box and try and teach her to be a prankster like him, does anybody want to imagine what the MonsterClown would have done to her?
* In the BadFuture of "Time and Punishment" (and the AlternateUniverse of the comics), where did [[ArchEnemy Negaduck]] go? Where did the other heroes of St. Canard, including [[LoveInterest Morgana]], go? Why did the democratic government allow one man to have totalitarian control of a city inside their borders, UsefulNotes/JosefStalin style, without trying to take him out? Just how much power did he amass?
* In the second arc of the Boom Studios comic book, an unknown presence [[spoiler:that later turns out to be Paddywhack]] eats people that are near the ocean alive. [[spoiler:Paddywhack]] gets defeated, but it is never explained what happened to his victims. This is made worse because nobody expresses concern for their whereabouts at the end of the arc.
* Ordinary Guy's ''life''. Is it any wonder he [[spoiler: snapped and became villainous?]] He is the only one without superpowers living on a planet where ''everyone'' has superpowers, and they constantly save him from ''everything'', not allowing him to do his life freely. [[spoiler: Now that Darkwing Duck taught them about villainy and that Ordinary Guy was defeated, there's a possibility he's going to become their [[ButtMonkey punching bag.]]]]
* "When you're Drake Mallard, what kind of job do you have?" "Yeah, how do you pay your bills?"
** How about "How can you manage to hold down a (presumably) eight-hour-a-day job ''and'' a (presumably) eight-hour-a-night crimefighting gig while also getting (presumably) eight hours of sleep (at some point?) ''and'' raising a ten-year-old kid??"
** Seeing as how DW is routinely shown testing out gadgets and weapons supplied by SHUSH, it's likely he's "officially" listed as a professional gadget-tester, and paid accordingly.
*** It's pretty much confirmed in the comic series--Drake and Gosalyn had been living off of Darkwing's SHUSH stipend, and when it ran out, Drake got a full time job at Quackwerks.
* Launchpad lives with Drake, and is seen with him constantly in public. Then as Darkwing, he's still there as his sidekick (and Launchpad doesn't wear a mask or disguise). Yet no one seems to have put two and two together. [[spoiler: As of Comic #3, [=NegaDuck=] FINALLY put two and two together after noticing Launchpad coming out of a laundromat with two different pairs of Darkwing's clothes...]]
-->[[spoiler:'''[=NegaDuck=]''': And that got me thinking... That was the loose end I needed to untangle '''everything.''' [[OhCrap Now I can ENJOY ripping your life to SHREDS]].]]
** [[spoiler:But as a Evil counterpart from a MirrorUniverse, shouldn't he already know this?]]
*** [[spoiler:Not necessarily. There may have been Nega versions of Launchpad, Gosalyn, and Honker that [=NegaDuck=] tried to make as his own "family" that didn't work out so well from that old episode, but they never knew who [=NegaDuck=] really was. And besides, he DID say that he was watching the Mallard household for ''months'' after he saw Launchpad, presumably to make sure he was on to something.]]
*** But that still doesn't make sense. [[spoiler: [=NegaDuck=] apparently lived in the same house as Drake in the Negaverse, which either means "Drake Mallard" isn't just an identity but truly who they are outside of the mask, or...it's just an amazing coincidence of epic proportions. And he even used Canard Tower as a base of operations, didn't he? Seriously, the fact he didn't know just doesn't make sense at all.]]
*** [[spoiler: Negaduck didn't use his real identity at all, so he didn't think Darkwing bothered with it either. When he realizes this isn't the case, he zeroes in on the Mallard house almost immediately and watches for months.]]
*** Yeah, but you'd think he would at least check on that little possibility. Especially since Darkwing headed for the very house he lives in, in his own dimension, which is occupied by Good Gosalyn in the Negaverse...who is explicitly said to be Negaduck's ward. Plus, Evil Launchpad heads there as well, so...yeah. Still a plot hole.
*** It's just being assumed that the Nega-Audubon Bay Bridge tower is Negaduck's actual base. It might be more of a private getaway and prison for those times when you want your enemies tortured to death in a quiet intimate gathering instead of the usual big productions in the castle downtown. Especially if he wanted Nega-Gosalyn to have that as the last thing she sees while suffocating to death in the same room as the horribly-mutilated corpse of the good version of himself. As far as the Avian Way address? Sounds reasonable that he'd have at least Nega-Launchpad there ... and picked it out for its neighbourhood, especially given who lives next door. (Which makes you wonder why Darkwing picked the house he did. I'm working on explaining that; keep an eye on a favoured FanFiction site, of course!)
*** "Drake Mallard" was DW's original identity before becoming Darkwing; as DW's MirrorUniverse double Negaduck's original identity should be Drake Mallard as well.
*** As Darkwing's MirrorUniverse counterpart, [=NegaDuck=] truly is Darkwing's opposite in much the same way the ''Star Trek'' mirror characters were the prime universe characters' opposites: in some, but not all aspects. In the aspects where they're not opposites, Darkwing and [=NegaDuck=] are in fact exactly the same; and one of those aspects is that Darkwing had an obsessive attention to detail that allowed him to track a small and needlessly complicated clue to [=NegaDuck=]'s lair... while [[FailedASpotCheck overlooking the big black Fearsome Five flag [=NegaDuck=] had hoisted over the same building]]. The reason [=NegaDuck=] failed to realize where Darkwing Duck lives as a civilian? Both ducks are bound by the same RuleOfFunny, and they both have the tendency to overlook the screamingly obvious while searching for an insanely complicated solution from an obscure clue.
** For that matter, shouldn't Liquidator know DW's secret identity? His origin episode ends with him as a statue in Drake's lawn.
*** In Liquidator's case he may have seen it as insult to injury. I.e., Darkwing pours cement into him to stop him from kidnapping a girl, and the girl's father finds the statue and uses it to improve his garden. As for the key question, a villain refers to Launchpad, Gosalyn, and Honker as Darkwing's fan club. So it's not a big stretch for people to think Drake's roommate spends his free time following Darkwing to watch his exploits. Gosalyn even forms a true fan club at on point so it's not a big stretch.
** Speaking of which, has the prison staff just been letting [=NegaDuck=] keep his mask on in jail? You'd think at some point they would have removed his costume and seen ''Drake Mallard's'' face.
* In the second part of "Just Us Justice Ducks", Negaduck says that the Fearsome Four can run the city and in exchange he will keep the stolen money. When they get mad and question him on why he gets to keep all of the money, he threatens them with an active chainsaw. The others being afraid make sense, but ''why'' was ''Liquidator'' scared of a ''chainsaw'' considering that his ''entire body is made of water''?
** Because Negaduck is ''just that scary''.
* Pollen is the plant equivilant of sperm. So when Bushroot does his dandruff attack does that mean he's basically masturbating at whoever is the recipient?
