These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Darkwing Duck
Angst? What Angst?: Gosalyn is quite chipper for a little kid whose granddad was murdered before the first episode.
Even weirder in issue #4 of the comic book when everyone confronts Taurus Bulba and she doesn't even mention her grandpa's death, only that Bulba kidnapped her for the code to his Ramrod machine. You'd think it might come up. To be fair, she might not know as Taurus's goon did in her grandfather, and she might not know they were working for him.
Oh, she knew who they were working for, DW mentions it in the pilot. But it's quite possible she didn't want to talk about her Grandpa's death.
It still had an element of Dull Surprise, though. And rather out of character for the kid who went momentarily catatonic the last time Bulba showed up in the show. Her speech to him bordered on it as well.
Complete Monster: Taurus Bulba, unlike the rest of the villains, has almost no ounce of comedy at all. Taurus had Gosalyn's grandfather murdered, and when he was trying to get the code for the ram rod, he threatened to drop Gosalyn off a building if Darkwing didn't get the code. He had no proof that Darkwing was told of a code, and was still willing to try it, and when he was resurrected by F.O.W.L., he destroyed the dang place. All played completely seriously.
Yes, and mixing this trope with a Love Potion is a disturbing combination...
On a less 'mortal enemies' note, Darkwing and Grizlicoff have some of this.
Darkwing and Neptunia had some of this in her debut episode when she kisses him on the cheek at the end.
Also Darkwing and Isis "Icy" Vanderchill.
Fridge Logic: That Splatter Pheonix wasn't very freaked out at being melted into a puddle by turpentine suggest she was aware that she's a cartoon character.
Fridge Horror: 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 Monster Clown would have done to her?
Growing the Beard: The show went through a few phases, notably starting out as a spy show parody since that's what the early episodes were designed as before some changes in the show's direction mid production.
Ho Yay: DW and Launchpad. Search your feelings, you know it to be true.
Quackerjack and Megavolt too.
Liquidator and Bushroot, though not quite as common as Quackerjack and Megavolt.
Jerkass Woobie: Because of his power to store and release electricity from himself (as well as being more than a little crazy), Megavolt was sometimes considered less than human (er, less than a rat, or a mole, or... well, you get the idea). One comic story in the Disney Adventures magazine recounted various criminal organizations trying to capture Megavolt and treating him as a slave. One of the gangsters even ominously told Megavolt that he planned on "converting his energy" (by essentially turning him into a living generator with mush for brains).
In his first apperance in the pilot, we see he's been operating his criminal ring from inside prison for some time, even using the license plate making area to turn part of the prison into an airship ready for his escape. He has his men kill Gosalyn's grandpa, making it look like an accident, finds Darkwing's secret hideout, and nearly kills both Gosalyn and Darkwing.
Believed to be killed in an explosion, he appears again in the third season, body badly damaged, and life saved by F.O.W.L. turning him into a cyborg. They hope he will become one of their chief agents... he thanks them for saving him by blowing up thier base, and proclaiming he works for no one. Later in this episode he takes Gosalyn hostage, and when D.W. offer to do whatever he wants in exchange for her freedom, Bulba laughs and says he doesn't know what he wants yet... just for the fun of watching Darkwing squirm.
His next canon appearence was in the new comics series, when his cyborg body had an accident and he took on a Ghost in the Machine persona, creating Quackwerks, and using the corporation to take over the city in under a year... why? For revenge? No... just so he could gather every citizen, get them to say every word they know until he came across the activation word for the Gizmoduck suit.
Gosalyn: "So Quackworks taking over St. Canard was just a ruse to..."
Darkwing: "... net Bulba the Gizmoduck suit. Just to show he could!! We've all been trapped in another man's game."
Memetic Mutation: I am X, that Y (Ex.: "I am a can of tuna that has been expired!")
In "Just us Justice Ducks" when Negaduck decided to pull the switch in a case of Taking You with Me but when even after the heroes backed down, he decides to do it anyway, simply out of pure spite.
Negated Moment of Awesome: From the comic book- Issue #14's main villain was a cat in a metal suit who called himself 'Cat-Tankerous'. Considering there was already a trilogy of Darkwing Duck comics in Disney Adventures with a villain named Fluffy who was a cat in a metal suit, this would have been a prime opportunity to tie the two series' continuities together.
Slightly undercut by Quiverwing Darkwing, who also lost his Gosalyn, and, rather than go nuts as Darkwarrior did, took up her Quiverwing Quack hero persona to honor her instead. He later fights (and quickly defeats) Darkwarrior Duck.
The Woobie: Gosalyn, very effectively, in "Darkly Dawns the Duck", while she's still an orphan that feels unwanted. In later episodes she doesn't have that problem, and characterization in general is more shallow anyway.
