Darkwing Duck
1) Paddywhack's Box ends up at the Muddlefoot house, so he tries to terrorize them. It... Doesn't exactly go according to plan, and now he's helping Binkie make casserole for a dinner party he's invited to. Trust me, he's just as confused as anyone else.
2) The F5 spend a night sharing their backstories with each other, to mixed reactions.
3) Rewrite the events of Darkly Dawns The Duck, but in the Negaverse.
4) Liquidator gets unmutated temporarily and has to relearn how to be solid. Walking, breathing, eating — there's a lot for the Master Of All Liquids to remember.
5) Negaduck is pulled into Paddywhack's Box and suddenly finds himself wearing civilian clothes for the first time in years.
6) When Quackerjack is the only one that believes a random civilian's ramblings about a 'demon jack-in-the-box' terrorizing them, he must decide whether to help or leave them to Paddywhack's mercy...
7) Write a story that looks like an origin story for Darkwing, from highschool to training to his first few attempts at crime fighting, but with a twist ending; he renounces hero work and becomes a Supervillain. It's Negaduck's origin, in disguise.
8) Morgana and Paddywhack meet. If they fight, who wins? If they don't, well... who knows what could happen?
9) Someone, probably a civilian, decides to play along with Liquidator's salesman-speak, much to his delight and everyone else's annoyance.
10) An origin for heroes and villains of the pirate 'verse.
11) Much to his confusion and delight, Quackerjack finds a new customer base for his toys — monsters and/or mutants.
12) Megavolt gets amnesia and can't understand why he's so different from normal people. (Wanting to touch electrical sockets, feeling sympathy for toasters, etc)
13) Liquidator loves to relax in the ocean. Unfortunately for him, Neptunia lives there. Can they come to an understanding, or are the seven seas too small for the both of them?
14) Darkwing offhandedly mentions talking Mr Meekles off the ledge to Quackerjack — who hadn't known he'd nearly drive a man to s******.
Cue the cheerful toymaker having a bit of a heel realization and a breakdown.
15) AU where the F4 are civilians and roommates, either with or without their powers, and Negaduck's their landlord.
Bonus: Paddywhack is Quackerjack's stalker, and lives in the same building as they do.
16) Gosalyn Waddlemeyer is adopted by someone other than Drake Mallard — such as one of the villains. Some things change and some never will.
17) Negaduck travels to a world where the F4 are all missing some important trait, and are miserable. He makes it his personal mission to fix things for reasons he'd rather not look at too closely.
(Megavolt living in some backwater and not having any engineering knowledge, Bushroot living in a city and wilting far away from nature, Liquidator toiling away in a small-time job with no ambition, Quackerjack having never created something in his life — that sort of thing)
18) Liquidator, Bushroot, or Megavolt meets someone with the same or similar powers as him. Will this person be friend, foe, or something more?
Or will they stay a fleeting, mysterious moment of connection, never to be repeated?
