When the Fearsome Five formed to take over St. Canard, Darkwing had to put his ego aside (but not before throwing a tantrum about wanting to be the only superhero in the city and being beaten by the Fearsome Five four times) and form a Five-Man Band of unique individuals to face them. The team itself only appears in the two parter "Just Us Justice Ducks" but the members make other appearances in the show.
The high-tech hero of Duckburg who is Launchpad's old work friend, Fenton, an accountant for Scrooge McDuck. Darkwing, a Hero with Bad Publicity in St. Canard, is jealous of how Gizmo Duck is universally accepted and trusted by the city. In turn, Gizmo Duck doesn't like Darkwing's vigilantism. Despite this however, they work well together, when they put the petty stuff aside.
- The Ace: Fenton Crackshell the person is rarely seen in the show, so all the audience sees is Gizmo Duck unintentionally show Darkwing up with St. Canard's admiration of him and his skill as a hero.
- Affectionate Parody: Of Robocop.
- Always Someone Better: Whenever Gizmoduck guest stars, he adds this element to the story. He is a truer, nobler, more all around impressive and famous superhero than Darkwing, apparently upstaging him without even noticing. On the first such occasion, Darkwing suffered the traditional inferiority complex that such a plot calls for, but after that episode disproved Gizmoduck's true superiority conclusively, Darkwing has since never shown any sign of Gizmoduck envy. Even so, during that first episode and every Gizmoduck episode since, Darkwing always resents him, treats him as unwelcome and unnecessary competition, even thinks of him as The Rival, despite Gizmoduck's routinely demonstrated and explicitly stated refusal to consider competitiveness as a motive fit for a true hero. This, if anything, only serves to infuriate Darkwing further, and despite Gizmoduck's repeated requests for mutually beneficial cooperation, he finds himself feuding with Darkwing again and again. It could be said that Darkwing himself is The Rival, and Gizmoduck is The Hero, despite the fact that Darkwing invariably triumphs in the end regardless of whether he agrees to team up with Gizmoduck, and in every episode where Gizmoduck is absent, Darkwing is unquestionably The Hero.
- Break the Haughty: At least once in the show.
- By the Power of Grayskull!: "Blathering blatherskite!"
- The Cape: An Affectionate Parody of this, in the same way Darkwing is an Affectionate Parody of The Cowl."I am here out of my sense of civic duty! I go where I am needed, no matter how big or how small the crime!"
- Catchphrase: Also "Blathering blatherskite!"
- Clothes Make the Superman: His costume basically consists of all his gadgets.
- Do-Anything Robot: The suit is programed to do anything and use anything within it. From helicopter headgear all the way to giant sponges.
- Headbutting Heroes: He and Darkwing don't get along at all, though this sometimes turns into Vitriolic Best Buds when Darkwing gets over his ego and Giz shows off his better nature.
- The Lancer: Shares this role with Gosalyn when he appears. Any other time, he would be the ideal Hero, but since it's Darkwing's show...
- Large Ham:"This situation calls for the unique gizmo talents of GIZMODUCK!"
- Old Friend: During one episode, he stays at Darkwing's house briefly because Launchpad knows him from work (implicitly both of them working for Scrooge). Fenton/Gizmoduck proceeds to drive Darkwing crazy.
- Rousing Speech: Fond of long, rambling, highly hammy and intentionally narmful inspirational speeches that almost always end with someone getting the better of him.
- Something Person: He is a duck with a lot of gizmos.
- Super Hero: A long-standing beloved superhero.
- Transplant: From DuckTales (1987).
- Vocal Evolution: His in-character voice as Gizmo was less booming than it was back on DuckTales (1987) and sounded much closer to his natural speaking voice as Fenton.
A sorceress and former CEO of "McCawber's Mushrooms" who shared a mutual attraction with Darkwing. Initially, she was a criminal, but eventually reforms, becomes Darkwing's girlfriend and earns his trust learning his secret identity. Almost always by her side is her three familiars, the bats Eek and Squeak and her grumbling tarantula Archie.
- Alliterative Name: Morgana McCawber
- Aloof Dark-Haired Girl: Her appearance fits this, she is significantly taller than Darkwing (and most other characters), and more developed than any other female on the show, with white feathers and black hair. She starts out very cool, but vampy, and very elegant. As she develops she becomes less aloof, but remains considerably more mature than Darkwing.
- Corrupt Corporate Executive: Initially, she was CEO of McCawber's Mushrooms and was a straight-up villain, but she eased into the side of good as her love for Darkwing grew.
- Damsel in Distress
- Dark Is Not Evil: Though she started off evil, she remained dark when she became good.
- Dating Catwoman: The Catwoman to Darkwing's Batman.
- Eerie Pale-Skinned Brunette: White feathers (skin) are pretty typical in Duckburg, but Morgana completes the look with her dark, Frankenstein's Bride hair and her penchant for the macabre.
- Expy: Her dress is similar in design to that of Morticia Addams and she is also similar to Lily Munster for having black hair with a white streak and being part of a Monster Mash family.
- Femme Fatalons: She had a set when she was villainous and still appeared when she became good, but not as much.
- Friendly Enemy: With Darkwing before her reformation, to the point she ends up teaming with him against the other villains in each appearance.
- Hair-Trigger Temper: Can go from zero to furious in record time, though some of the things Darkwing says to get her riled up are pretty bad. Especially when she's stressed out, watch what you say around her if you don't want to get zapped.
- HeelFace Turn: In "Ghoul of My Dreams", Morgana's feelings for Darkwing and the treachery of the episode's villain, Nodof, started the turn. By the time the Justice Ducks episodes happened, she was definitely on the side of good.
- Heroic Sacrifice: In the comics. She is brought back at the end of Dangerous Currency, which is now considered non-canon. The Joe Books omnibus, however, ends its revision of "Campaign Carnage" with her pets Eek, Squeak, and Archie happily looking at a glowing crystal ball, implying that she is still alive somewhere.
- Hot Witch: She is a powerful sorceress and, unlike the rest of the McCawber family, she is really attractive.
- Lady in Red: She wears red dress which ties in with her dark seductive character.
- Lady of Black Magic: She's elegant and composed, but cross her and she'll turn you into pudding or worse.
- Lethal Chef: An odd case. The food she cooks certainly sounds and looks disgusting, but Darkwing is the only one in-universe who even seems to notice. Everyone else loves it.
- A Lighter Shade of Black: In her first two appearances as villain, compared to Nodoff and board of directors for McCawber's Mushrooms Unlimited.
- Love Redeems: Again, her love of Darkwing was what converted her to a heroic character.
- Non-Mammal Mammaries: She is a duck, but tell that to her hourglass figure.
- One Head Taller: A good two heads taller than her boyfriend, at least...
- Perky Goth: After she formally becomes a good guy.
- Single Woman Seeks Good Man: It took Darkwing's heroics to change her ways.
- Skunk Stripe: Part of her Bride of Frankenstein look.
- Tiny Guy, Huge Girl: Darkwing is two heads shorter than Morgana.
- Tsundere: While she's normally quite sweet-natured, she is extremely dangerous when angered.
- The Ugly Guy's Hot Daughter: Her father is an elderly, green-feathered, hunch-backed vampire. Morgana, as stated before, is a tall, elegant sorceress.
- The Vamp: Only acted this way in her first appearance, afterwards, she was either a conflicted villain or a hero.
A former duck janitor transformed into a stegosaurus by the Mad Scientist Dr. Fossil. Well meaning and friendly, Stegmutt is also powerful, destructive, gullible and pretty clumsy.
- Accidental Hero: Stopped Quackerjack's gigantic joke teeth from terrorizing St. Canard's citizens and then smacked the villain away with his tail when he was being snarky to him. All of this was done when Stegmutt wasn't paying attention.
- Adorkable: Stegmutt's klutziness mixed with his childlike innocence and big heart makes him this trope.
- Almighty Janitor: Before his transformation he literally was a janitor, afterwards, he works as a hot dog vendor.
- Beware My Stinger Tail: Being a Stegosaurus. He sometimes knocks people into a wall with his tail accidentally when he gets too excited.
- The Big Guy: Takes this role from Launchpad in the episodes when he's a hero. He's by far the strongest member of the Justice Ducks.
- Catchphrase:"Oh Boy!"
- Cowardly Lion: He's REALLY strong physically, but despite that, he tends to scare pretty easily.
- Destructive Savior/Does Not Know His Own Strength: He can destroy things but just by slightly tapping them.
- Dumb Dinos: Stegmutt is good-hearted but, living up to the stereotype of the dinosaur he's become, not too bright.
- Dumb Muscle: More naive than dumb, but he's still a little slow on the uptake. As a Stegosaurus, he has a lot of muscle.
- Everything's Better with Dinosaurs: Mutated into a Stegosaurus by Dr. Fossil.
- Gentle Giant: When he's actually being careful and even then, usually around kids.
- Giant Mook: Was one under Dr. Fossil.
- HeelFace Turn: Initially, fought for the wrong side, but soon learned that Dr. Fossil was crazy and his plan would ruin the world (for starters, no more chocolate-covered sandwich cookies).
- Honor Before Reason: Darkwing, pressed for time to stop Liquadator and Bushroot, bought a hot dog from Stegmutt. He's so determined to give Darkwing his change back, he ends up endangering Darkwing and then tricked into a game of "Put out the Darkwing".
- Ignorant Minion: Gosalyn and Honker had to tell him that Dr. Fossil was evil, even though he practically did little to hide his true nature.
- Keet: The simplest things excite him.
- A Lizard Named "Liz": A Stegosaurus named Stegmutt.
- Metamorphosis: Stegmutt has shown no signs of changing back into a duck.
- Minion with an F in Evil: Partially, because he wasn't evil, and until Gosalyn and Honker told him otherwise, he didn't think Dr. Fossil was either.
- Stock Dinosaurs: He's a walking, talking Stegosaurus.
- Super Strength: One of the things that makes him both a threat and a liability.
Originally a regular fish who was transformed by toxic chemicals, she was angered at St. Canard for polluting the ocean. She initially sought her revenge, but came to terms with Darkwing, who is helping to keep trash out of the ocean. She controls sea creatures by playing a song through a conch shell and also wields a trident. Often seen with her companion, a giant octopus named Hal.
- Barefoot Cartoon Animal: Although she has flippers instead of feet.
- Cute Bruiser: A tiny little fish with tons of power. She even can swim in the Liquidator and force him to spin around.
- Deadpan Snarker: One of the snarkiest.
- Fish Person: Not a duck and, unlike Stegmutt, never "used to be".
- Good Is Not Nice: Not the most sociable around land-dwellers and can be downright nasty when angered, but when innocents are in danger (land-dwellers included) she steps up and takes action.
- Hair-Trigger Temper: She is quick to anger, of which Darkwing and Liquidator have felt most of her wrath.
- HeelFace Turn: She never really was a villain in the traditional sense and only threatened St. Canard because she was protecting her home. After she and Darkwing worked it out, she became his ally.
- Leitmotif: Sultry, heroic saxophone solo.
- Metamorphosis: Changed into an anthropomorphic fish woman and cannot change back into a normal fish.
- The Napoleon: Look at the other tropes, this does not come as a surprise.
- Pint-Sized Powerhouse: Depicted as such in her first appearance, less so in her later ones.
- Prongs of Poseidon: Her trident.
- Sour Supporter: Doesn't exactly like the surface world and isn't interested in being its protector at all, but her good heart makes her come back after seeing she's really needed.
- Speaks Fluent Animal: With the exception of her right-hand octopus, who has to mime because he doesn't have a mouth.
- Super Strength: Once threw Darkwing across half of St. Canard.
- Tertiary Sexual Characteristics: Eyelashes, prominent pink lips and pink ridges above her eyes.
- Toxic Waste Can Do Anything: She was mutated from a regular fish into a humanoid half-fish by a barrel of radioactive waste.
- Well-Intentioned Extremist: See HeelFace Turn.
A peacekeeping super-secret organization headed by J. Gander Hooter, trusted with handling international affairs - usually involving their primary foe, F.O.W.L. - that the regular authorities cannot. When S.H.U.S.H. is in need of a more unorthodox solution, they bring in Darkwing Duck. The organization is so secret that not even its leader knows what "S.H.U.S.H." stands for.
The head of S.H.U.S.H. who brings Darkwing Duck in on several F.O.W.L. missions.
- Benevolent Boss: Absent-minded, a bit on the eccentric side, but an effective and fair mission control to Darkwing and the agents of S.H.U.S.H., generous with praise and sternly serious about getting results on protecting the world from F.O.W.L.
- The Commissioner Gordon: Has a similar relationship the trope namer had with Batman.
- Mission Control: To Darkwing when he's assigned to S.H.U.S.H. assignments.
- Only Sane Man: Probably the most rational character in the entire series.
- Punny Name: A pun on the name of FBI director J. Edgar Hoover.
- Reasonable Authority Figure: Aids Darkwing with whatever he needs for his missions and tries to keep him and Grizzlikof from killing each other.
The head agent of S.H.U.S.H. who clashes with Darkwing on how to handle F.O.W.L.. He is the antithesis to Darkwing, operating strictly and uncompromisingly by the S.H.U.S.H. handbook.
- Commander Contrarian: He often objects to J. Gander Hooter's relationship with Darkwing Duck, and the latter's involvement with S.H.U.S.H.'s cases, because Darkwing isn't an agent and doesn't follow the S.H.U.S.H. rulebook.
- Genius Bruiser: He is both an intelligent agent and extremely strong.
- Grumpy Bear: He is grumpy (mainly around Darkwing) and a literal bear.
- Husky Russkie: As the name might suggest, he is Russian, and he is most definitely husky.
- Jerk with a Heart of Gold: He never gets along with Darkwing Duck, but can work together with him when he needs to and does desire to do good.
- A Lizard Named "Liz": A grizzly bear named Grizzlikof.
- Malaproper: He tends to confuse his words. For example, in the episode "Dirty Money", he says "obstinate course" when he means "obstacle course".

- Obstructive Bureaucrat: Vladimir is very by-the-book compared to Darkwing.
- The Rival: To Darkwing on S.H.U.S.H. matters.
- Russian Guy Suffers Most: Darkwing's antics frequently result in him being humiliated.
- Sympathetic Inspector Antagonist: He is always attempting to prove that Darkwing Duck can't be trusted by S.H.U.S.H.
A scientist and inventor who is the head of S.H.U.S.H.'s research division. Somewhat absent-minded and slightly sadistic, her ultimate goal is to win the Nobel Prize for her inventions.
- Absent-Minded Professor: She is not always focusing on what is important.
- Eerie Pale-Skinned Brunette: She has this appearance due to having black hair and white feathers and can also be unnerving because of her lack of concern when her inventions cause problems.
- Gadgeteer Genius: She makes different devices for Darkwing to use on his S.H.U.S.H. missions.
- Hot Scientist: She is a scientist and inventor working for S.H.U.S.H. and she isn't by any means unattractive.
- Labcoat of Science and Medicine: Her usual attire.
- Mad Scientist: It is occasionally implied that she isn't all there.
- Morally Ambiguous Doctorate: Some of her methods of testing her inventions are rather... reckless, and she's quite willing to use other people as subjects.
- Punny Name: Cerebellum.
S.H.U.S.H.'s greatest secret agent, who didn't believe in using gimmicks and gadgets in the line of duty. He appears for the first and only time in the episode "Like in Blunt."
- Berserk Button: Blunt hates the films that were loosely based off his career, considering them rubbish. It doesn't help their efforts to work together that Darkwing is a big fan of the movies and keeps mentioning them.
- Big Ol' Eyebrows: Big, bushy, grey eyebrows.
- Deadpan Snarker: Makes several cutting remarks about how he views Darkwing as being inept when it comes to crime-fighting.
- Expy: To James Bond and Derek Flint.
- Good Is Not Nice: He's one of S.H.U.S.H.'s best agents and he comes out of retirement to help retrieve a list of agents' names before any of the villains at Sharp's auction have a chance to buy it and wreak havoc with the information. He's also supercilious, endlessly critical, and a loner by choice.
- Good Old Ways: Derek Blunt never used any fancy gadgets or technologies on his missions. After cooperating with Darkwing, he learns that some of it is quite useful when used alongside intuition and natural skill (While Darkwing, conversely, learns not to rely too heavily on gimmicks).
- The Mean Brit: He talks in a British accent and criticizes Darkwing endlessly through most of the episode (though, as even Launchpad agreed, some of his criticisms were valid). He lightens up near the end.
- Noble Bird of Prey: He is an anthropomorphic bald eagle.
The neighbors in Drake/Darkwing's Möbius Neighborhood and Honker's family. Unlike Honker, they're really aren't that bright; otherwise they would have discovered that their neighbor was Darkwing Duck a long time ago. With the exception of Honker, Drake cannot stand them, while Gosalyn and Launchpad don't seem to mind them.
A loving but oblivious couple who live next door to the Mallards. Herb is a Quackerware (their version of Tupperware) salesman and Binkie's a homemaker. Herb also loves to barbecue and watch his favorite show, Pelican's Island. They are very friendly, but also unintentionally intrusive, and they're unaware how much of a brat their oldest son Tank is.
- Adults Are Useless: They do absolutely nothing to punish Tank for bullying his brother Honker. In "You Sweat Your Life", Herb even implies that Tank cut off his grandfather's leg when he was a baby, yet he relates the story as if it's completely normal for your child to dismember your father or father-in-law.
- Always Identical Twins: "Twin Beaks" reveals that Binkie has a twin sister named Trudy who, aside from an opposite color scheme and an eye patch, is completely identical to her.
- Berserk Button: Herb, of all characters, is shown to have one in "The Merchant of Menace" when facing off against evil salesman Weasel Loman.Weasel: "Quackerware's a tenth rate product! It took me to realize its true potential!"
Herb: "You can disgrace yourself, and you can disgrace me, Weasel. But when you start messin' with Quackerware, that's it for old Herb Muddlefoot! Come on!"
- Cloudcuckoolander: They're both pretty kooky.
- The Ditz: Neither of them are very bright. It's amazing that their youngest son is a genius.
- Drop-In Character: Both of them, but Herb mostly.
- Happily Married: They're affectionate towards each other.
- Hawaiian-Shirted Tourist: Herb always wears a Hawaiian shirt even when he's not on a holiday.
- Housewife: Binkie spends a lot of time cleaning the house and cooking.
- Idiot Houdini: The episode "Inside Binkie's Brain" has Binkie cause trouble throughout all of St. Canard in her attempts to make the city safer and suffer no repercussions for her actions simply because she's too dumb to understand that she's done anything wrong.
- Let's Get Dangerous!: Herb in one episode where he shows heretofore unknown sumo skills.
- Nice Guy: They're an exceedingly friendly pair, even if they are exceedingly oblivious.
- No Celebrities Were Harmed: They are extreme caricatures of Ward and June Cleaver.
- Parental Obliviousness: Their first kid is a brat, but they don't seem to notice.
- Proper Lady: Binkie, who tries to get Gosalyn to act more lady-like as well.
- Took a Level in Badass: Binkie Muddlefoot when she hits her head and temporarily becomes "The Canardian Guardian, Champion Of Safety." Though half the things she tried to do to make things safe ended up making things hilariously worse...
- Wiki Walk: A lot of Herb's conversations function this way.
A really mean little boy, which is something his parents fail to realize. Honker is his usual target, but he has also been known to make fun of Gosalyn and attack Drake.
- Big Brother Bully: He's Honker's older brother and loves to torment him.
- Bratty Half-Pint: Despite his size, he still qualifies for this in spades.
- Evil Redhead: Not a lethally evil, but there's little good to be found with him.
- Fiery Redhead: He has red hair and is often quite bellicose.
- In-Series Nickname: Everyone mostly refer to him as "Tank".
- Jerk Jock: He is tough and mean at the same time.
- Jerk with a Heart of Jerk: In "A Brush With Oblivion" he has a surprising Pet the Dog moment where he's the only one who sticks up for Honker when he's blamed for Splatter Phoenix's crimes, and even helps him escape from the house after their parents ground him. Then after Honker's gone he immediately proceeds to tattle on him to Herb and Benkie, showing he helped Honker out just so he could get him in further trouble.
- Jerkass: Not a nice guy by any stretch.
- Kids Are Cruel: Even when he isn't picking on his brother, he can be quite insensitive.
- Laser-Guided Karma: He gets what comes to him usually.
- Too Dumb to Live: Some of the characters he's attempted to hassle include Flarg and Bushroot. It doesn't end well for him.
- Trash Talk: He frequently insults the people he messes with.
- Troubling Unchildlike Behavior: His father implies in "You Sweat Your Life" that he cut off his grandfather's leg with a chainsaw when he was a baby. Granted, it was a wooden leg, but still.
A humanoid Superhero who lives on Mertz, a planet of superheroes with only one "ordinary guy" to save. Initially, he was a failure due to his lack of intelligence and his weakness—when hearing a bell ring, he dances uncontrollably until he hears a whistle. Darkwing trains him to turn his weaknesses into strengths and save the day.
- Bald of Awesome: While he had hair in his first appearance, "Planet of the Capes" depicts him as bald.
- Bigger on the Inside: His spaceship-helmet, which could somehow fit both him and Darkwing inside it when they traveled to his home planet.
- Catchphrase: Utters a weak "woopsie" whenever he screws up.
- Crouching Moron, Hidden Badass: He's extremely dumb, but he's a huge Super Power Lottery winner, pretty much the main thing keep him from being ridiculously overpowered is that he's so dumb.
- Dance Battler: How he ultimately turns his weakness - dancing uncontrollably when he hears a bell ring - into a strength; specifically, he deliberately chooses to emulate MC Hammer and apply the resulting bombastic breakdance-style moves as superhumanly fast dodges and crushing blows. It's actually more precise and effective than his normal combat technique!
- The Ditz: Not the brightest bulb in the box.
- Does Not Know His Own Strength: His other weaksauce weakness. For him, shaking someone's hand without crushing it is an achievement, and not ripping a door off its hinges when opening it is a bona-fide miracle. Surprisingly, this flaw goes away when he finally figures out how to weaponize his dancing, and in that state he becomes perfectly capable of interacting with everyday objects without destroying them.
- Dumb Muscle: He's dim, but he's also really really powerful.
- Everyone is a Super: Mertz itself.
- Eye Beams: His comet vision can freeze stuff.
- Flying Brick: His superpower set.
- Human Aliens: He and all other inhabitants of Mertz look like humans, which is very odd considering that everyone else on the show is an anthropomorphic animal.
- Involuntary Dance: Hearing a bell ringing causes him to start dancing.
- Lantern Jaw of Justice: An exaggeration of the trope.
- Nice Hat: The helmet he wears on his head, which doubles as his spaceship.
- Planet of Hats: Mertz, his homeworld, is a planet of superheroes.
- Something Person: Being a superhero, it comes with the territory.
- Super Strength: He is very strong, a trait shared many inhabitants of his home planet.
- Top-Heavy Guy: A very triumphant example of this trope. With so much mass in his upper body, it's amazing he can still walk with his small legs.
- Weaksauce Weakness: The bell thing. One "ding-a-ling!" and he starts uncontrollably strutting and/or pirouetting with no ability to fly or apply his strength. The only thing that lets him stop is hearing a whistle.
Darkwing's master in Quack Fu, who is at first disappointed at him for not learning the "belly bounce" technique and for using gadgets and weapons to fight with. He was corrupted by money and fame and tried to use a dragon in his plans to take over Kung Pow city. Darkwing stops the dragon in the end using the "belly bounce" and earns his master's respect.
- Acrofatic: Quite pudgy, but capable of handsprings and backflips
- Broken Pedestal: After Darkwing realizes that Goose Lee had gone evil.
- Foo Fu: Quack Fu
- HeelFace Revolving Door: Started as a face (when he was training Darkwing), got corrupt more recently but still prior to the episode, and turned face again during it.
- Karma Houdini: Darkwing doesn't punish him for his actions and he even gets the theme park he wanted. Though he is at least remorseful for what he's unleashed...
- No Celebrities Were Harmed: Mainly Bruce Lee (his name) and Pat Morita (his voice, changing from traditional Asian to more American sounding).
- Old Master: He trained Darkwing in martial arts.
- "Well Done, Son!" Guy: To Darkwing.
When Darkwing was accidentally zapped by Megavolt's tron splitter, he was separated into purely good and purely evil halves. The good half was nice to a fault. However, after being galvanized via another zap from the tron splitter, he ends up becoming supercharged and able to save the day even with his pacifistic tendencies. Was remerged with NegaDuck I back into the regular Darkwing.
- Actual Pacifist: Incapable of violence, even in self-defense.
- Badass Pacifist: Despite being so nonviolent he won't even stop on a bug, he manages to simultaneously get out of a deathtrap his dark side put him in and free a trapped Launchpad and Gosalyn. He even knocked NegaDuck I out by complete accident.
- Butt-Monkey: Due to being identical in appearance to his evil counterpart, combined with his unwillingness to fight back, he ends up taking a lot of abuse at the hands of NegaDuck I's victims.
- Good Is Impotent: His unwillingness to resort to combat makes him completely ineffective in stopping NegaDuck's rampage at first.
- Good Parents: He does not at all shame Gosalyn for breaking his statue of himself.
- Incorruptible Pure Pureness: Turned Up to Eleven post-galvanization.
- Literal Split Personality: Darkwing's good half.
- Made of Good: He is the personification of all that is good within Darkwing.
- Mistaken for Badass: Upon stepping into a Bad-Guy Bar that NegaDuck I had just terrorized about a minute ago.
- Nice Guy: He doesn't bear any hostility, not even to those who attack him when they mistake him for NegaDuck.
PosiDuck post-galvanization, in addition to most of the above:
- An Aesop: He continuously spouts these off, even when it's falling on deaf ears.
- Batman Gambit: He manipulates NegaDuck I's destructive habits in such a way as to completely undo all of the destruction caused by him in a single move.
- Friend to All Living Things: Inverted Negaduck I's Walking Wasteland, he repairs everything he gets near.
- Light Is Good: He is Darkwing's good half and now has a bright glow around his body.
- Power Glows: A pink aura, no less.
- Reality Warper: Seems to be capable of freely mending and restoring any sort of damage done to St. Canard.
- Super Mode: The galvanization significantly boosted PosiDuck's abilities.
- Took a Level in Badass: He's able to "fight" the super-charged Negaduck I to a standstill without even laying so much as a finger on him.
Star of the fictional video game in the series. When Darkwing was once trapped inside his video game, he teamed up with Whiffle (controlled by Gosalyn in the real world) to fight his way out.
- Catchphrase: "Whiffle, ho!"
- Expy: He's clearly based on Mega Man. In the comics we later here about an MMO based around him, "World of Whifflecraft."
- One-Hit-Point Wonder: One successful hit is enough to take him out.
- They Killed Kenny Again: He gets repeatedly killed by his enemy, the Weasel, and once accidentally by Darkwing. Justified, since he's a video game character.
A stretchable hero who only shows up in the episode "Mutantcy on the Bouncy". He helps Darkwing defeat Cement Head.
- Adorkable: He's rather likable due to being nervous all the time and desperately wanting to prove he's not a bad guy.
- Alliterative Name: His real name is Clovis Cluckenhoff.
- Clear My Name: He ends up at odds with Darkwing because Cement Head framed him for his crimes.
- I Love Nuclear Power: He was born with his powers because his parents were exposed to radiation at a plastics factory.
- Momma's Boy: When Darkwing first attempts to arrest him, his first concern is what his mother will think of him getting in trouble with the law.
- Punny Name: It is probably no coincidence that he shares his name with a prop commonly used by comedians.
- Rubber Man: He can stretch his body into any shape.
