The show's eponymous heroes. Jake Clawson and Chance Furlong, were Enforcers until an, er, misunderstanding with Commander Feral got them kicked off the force and demoted to garage mechanics. However, they used the military salvage that's regularly dropped off at Jake & Chance's Garage to become Razor and T-Bone, aka the SWAT Kats—two high-tech heroes who defend MegaKat City from an endless parade of super villains, Aliens and Monsters.
Tropes associated with both SWAT Kats:
- Abnormal Ammo: Let's see, they use missiles with functions such as electric shocks (Megavolt/Scrambler), sonic emitters (Banshee), wire clippers (Wire-Clipper), capture nets (Octopus, Spider), drills (Drop-Tops, Moles, Drill-Bits, Cookie Cutters), and buzz saws (Buzzsaws, Groundhogs, Shredders, Slicers). And who could forget the cement-shooting machine guns?
- Badass Normal: They have no special powers, just their brains, guts and technology.
- Badbutt: Ace Pilots and skilled hand-to-hand combatants, but the most vulgar they ever get is the word "crud." They also throw back cans of condensed milk as if it was beer.
- Barefoot Cartoon Animal: In their pilot suits.
- Blank White Eyes: In their SWAT Kats outfits.
- Brought Down to Badass: In "SWAT Kats Unplugged", the heroes' Turbokat Jet had their weapons systems disabled by Hard Drive, leaving them practically unarmed. Didn't mean they were helpless in a dog fight, though. Despite Hard Drive's armed to the teeth plane, the SWAT Kats managed to beat him by simply dumping by hand a barrel of paint they happened to have on board on his windshield.
- Cool Helmet: Their helmets are stylish.
- Cool Plane: The Turbokat, which they built out of scrap metal and spare parts.
- Destructive Savior: For all the good they do, Feral's right that they cause a lot of damage while fighting their enemies.
- Distressed Dude: They've both been captured and tied up by the villains here and there.
- Fingerless Gloves: Both SWAT Kats wear them.
- Irisless Eye Mask Of Mystery: Jake Clawson and Chance Furlong have normal irises while working in Megakat City's scrapyard. However, when villains threaten MegaKat City, they wear bandannas tied around the tops of their heads that make their eyes seem irisless, an understandable precaution to prevent Commander Feral or any of his Enforcers from recognizing them.
- Only Known by Their Nickname: You can pretty much count the number of times their real names have been used on one hand.
- Those Two Guys: They stick together like all the best duos should.
This fearless air ace is the best—and toughest—pilot in the sky. T-Bone's flying and fighting skills make him "a criminal's worst nightmare" in the air or on the ground.
Tropes associated with T-Bone:
- Ace Pilot: Is the main pilot of the duo and has some rad moves with the Turbokat.
- The Big Guy: He has a burly, muscular physique.
- Boisterous Bruiser: Upon taking down his enemies, he'll often brag about his skills as an Ace Pilot.
- Compressed Vice: He has a few phobias that are introduced in an episode and then never come up again:
- His fear of insects in "The Ci-Kat-A." Never before mentioned, and never comes up after the episode. Weirder still, nothing is done with it in the story - situations you'd think they were setting the phobic T-Bone up for (being cocooned and later snatched out of the Turbokat by the Ci-Kat-A) involve Razor, instead, and T-Bone never really needs to face, or overcome, his fear.
- His fear of swimming in "Mutation City." He does overcome this, although it never gets mentioned again. Jake, at least, was unaware of this phobia and an explanation is offered for why it's never come up before, because Chance simply never talked about it out of embarrassment.
- Dating Catwoman: In "Cry Turmoil", T-Bone is genuinely attracted to Turmoil ("She's kind of cool, in a nasty sort of way"), but his duty to stop her is clear.
- Distressed Dude: In "Night of the Dark Kat," he and Razor get captured and tied up.
- Drives Like Crazy: Considering he's an Ace Pilot, T-Bone also has mad driving skills as seen in "Night of the Dark Kat" where he, Razor, and Callie were in a police chase.
- Fake Defector: In "Cry Turmoil", he pretends to join the titular villain's gang in order to stop her.
- Genius Bruiser: He's really strong, and the best pilot anywhere.
- Guttural Growler: Somewhat with T-Bone, as he also speaks normally, but, being an anthro cat, he tends to growl his words as well.
- Manchild: T-Bone is shown enjoying Scaredy Kat cartoons (in numerous episodes) and reading the comic book Kat Kommandoes (in "A Bright and Shiny Future"). He shows disdain for more adult humor like "The David Litterbin Show."
- Red Oni, Blue Oni: The red to Razor's blue.
- Super Drowning Skills: He can't swim, and stubbornly refused to learn how to, even when it would save his life. He ends up learning to save Razor from drowning near the end of "Mutation City."
The SWAT Kats' "High Tech Edge", Razor is an inventor who creates the team's vehicles and weapons. An effective fighter, Razor is also a "sure shot" who can nail the most elusive criminal with the TurboKat's missiles, which contain such gimmicks as circular saws, drill bits and capture nets.
Tropes associated with Razor:
- All There in the Manual: Jake's surname, Clawson, is never mentioned once in the entire series.
- Badass Bookworm: He's as good at fighting as he is at inventing.
- Catch-Phrase: "Bingo!", which he often shouts when his missiles connect.
- Compressed Vice: His tendency to cheat in his competitions with T-Bone. It only is shown in "The Wrath of Dark Kat."
- Distressed Dude: In "Night of the Dark Kat," he and T-Bone get captured and tied up. Later in "Cry Turmoil" he is put into manacles.
- Gadgeteer Genius: His specialty, as he creates the SWAT Kats' weapons and equipment.
- Improbable Aiming Skills: He's constantly stated to be the best shot of the two.
- My God, What Have I Done?/10-Minute Retirement: In "Razor's Edge", after he accidentally injures an elderly couple. Or so he thinks—it turns out to be another of Dark Kat's Evil Plans.
- Oblivious to Love: Is almost completely oblivious to Callie's feelings towards him.
- Only the Chosen May Wield: In "Bride of the Pastmaster", Razor inadvertently pulls the Dragon Sword out of a rock, which, according to Queen Calista, can only be removed by the one who would save them all from Pastmaster. Though T-Bone argues he "loosened it for him" when he failed to remove it earlier.
- The Smart Guy
The In Name Only leader of Megakat City, an old-fashioned pol who sounds like W.C. Fields with an Irish accent. He's cowardly and slightly corrupt, he wears an unconvincing toupee, and he puts at least as much effort into his golf game as running the city, but he's basically a likable comic relief character... usually.
Tropes associated with Mayor Manx:
- Angrish: Whenever he's angry.
- Inelegant Blubbering: Whenever he's scared.
- Arbitrary Skepticism: Even though he has personally been attacked by supernatural beings such as Madkat and the Red Lynx, he dismisses the islander's warnings about Volcanus in "Volcanus Erupts!" as "superstitious hoo-doo nonsense."
- Catch-Phrase: The closest thing he's got is a tendency to exclaim "Godfrey!", usually as part of his Angrish and Inelegant Blubbering.
- Dodgy Toupee: It doesn't even match what remaining hair he's got left, and its constantly flying off is a frequent Running Gag.
- Distressed Dude: Seems to be his only real function in the show from a plot standpoint much of the time.
- Fat Idiot: He's a not grotesquely overweight, but still pretty chubby, and definitely doesn't have much in the brains department.
- Last-Name Basis: Mayor Manx's first name is never revealed.
- Lovable Coward: When danger gets too close, you can always find him... running and hiding.
- Dirty Coward: The lovable part is completely thrown out the window in "The Giant Bacteria", when he and Callie are fleeing the titular monster and a helicopter shows to lift them to safety. Callie reaches the rope ladder first and barely even begins to climb when Manx actually shoves her off so he can climb first.
- Mayor Pain: Of the Incompetent variety.
- Office Golf: Unless he's at the course.
- Only I Can Kill Him: In "The Ghost Pilot", he learns that since he's a descendant of war hero the Blue Manx, he's the only one who can destroy the ghost of Red Lynx. He doesn't particularly want to and at first is happy to let the Enforcers or SWAT Kats handle it instead, it's just how the rules governing this kind of thing work.
- Scotireland: His accent is sometimes Scottish and sometimes more Irish.
- Taken for Granite: Of the non-rock variety. In "Chaos in Crystal," he was one of Shard's victims and got turned to crystal.
- Took a Level in Badass: In "The Ghost Pilot", he finally shoots down The Red Lynx when Razor tells him that if he doesn't, he won't get re-elected. His brief burst of courage doesn't last, though.
- Ultimate Authority Mayor: We never see a civil servant in the series higher up the political food chain than him (like a governor), and Commander Feral seems to answer directly to him and him alone.
- The Unintelligible/Angrish: When he's angry or afraid (both of which are often), Manx tends to just blather nonsensical gibberish.
The leader of the Enforcers, Feral is courageous and honest, but he's also arrogant, ill-tempered, narrow-minded, stubborn and rude. Worst of all, he regards the SWAT Kats as reckless vigilantes who are as dangerous as the villains they fight. Ironically, he's also indirectly responsible for the formation of the SWAT Kats in the first place; see Nice Job Breaking It, Hero!/Only I Can Kill Him for more details.
Tropes associated with Commander Feral:
- Badass Longcoat: He wears a very impressive greatcoat with gold trim and the Enforcer logo on the biceps.
- Benevolent Boss: His poor treatment of Chance and Jake in the flashback, his contempt for Steel, and his standoffish attitude as a superior officer aside, it's clear Feral cares about the Enforcers under his command.
- The Brigadier: Insofar as the Enforcers are very military-like in function, although Feral is a little more acerbic than most such characters who fit this trope.
- Brutal Honesty: Diplomacy is not one of Feral's virtues.
- By-the-Book Cop: By the time of the series. It's a bit muddier in the backstory.
- Can't Catch Up: He's a fairly good officer, if a bit pigheaded at times, but he's out of his league when dealing with the villains the SWAT Kats face.
- Catch-Phrase: "This is Feral! Bring me chopper backup!"
- "The Enforcers will handle this!"
- Determinator: He may not be able to ever keep up with the SWAT Kats and their various rogues, but that sure as heck doesn't stop him from trying.
- Distressed Dude: A few times, most notably in "The Wrath of Dark Kat" wherein he's bound and gagged.
- Enemy Mine: He may not care much for the SWAT Kats, but he can and will work together with them when the situation calls for it.
- Good Is Not Nice: He's the head of the city's military/police forces and he really does care about doing his job and protecting Megakat City. Doesn't mean he's a nice guy by any means, though.
- Hero Antagonist: The chief of police in Megakat City, who also wants to arrest the SWAT Kats. His interference also sometimes gets in the way of the SWAT Kats solving problems that they could have otherwise gotten over.
- Honor Before Reason: He wants to arrest the SWAT Kats and expose their identities in the process, but is not willing to break the law to do it. At the end of "Metal Urgency", when the Metallikats offer to give away the vigilantes' identities in exchange for their freedom, his response is this:"I don't deal with scum."
"Dont make a big deal about it. I just didnt want to owe those two hoods anything."
- When a surprised Callie Briggs questions why he refused the offer, he replies:
- Inspector Javert: Commander Feral is constantly talking about bringing the SWAT Kats in, believing them to be just as bad as the criminals and supernatural threats that they fight.
- Sympathetic Inspector Antagonist: He does have a point, though: the SWAT Kats are unsanctioned vigilantes illegally operating in the city, flying around in a souped-up fighter jet causing millions in damage with their arsenal of missiles whenever they show up.
- Jerkass Has a Point: His main issue with the SWAT Kats is the reckless endangerment and damage they cause when trying to apprehend villains.
- Jerk with a Heart of Gold: For all of his talk about wanting to arrest the SWAT Kats and calling them bandits, he's serving Megakat City selflessly, and is perfectly willing to let a few things slide when he knows he's outmatched.
- Lantern Jaw of Justice: He might be a jerk about it a lot of the time, but he's still definitely a good guy and he does definitely have one of these.
- Last-Name Basis: Feral's first name isn't revealed until very late in the series.
- Never My Fault: Back when Chance and Jake were still Enforcers, they had cornered Dark Kat, only for Feral to order them to fall back and let him handle it. When they refused, he actually knocked their jet out of the sky and into Enforcer headquarters, causing significant damage to the building and allowing Dark Kat to escape. Feral flat-out refused to acknowledge that the entire mess was his fault for interfering in the first place, even after Chance point-blank told him so, and placed all the blame on Chance and Jake, kicking them off the force and sentencing them to work at the salvage yard until they pay off the damages. It actually makes Chance and Jake upstaging him as the SWAT Kats throughout the series very satisfying.
- Nice Job Breaking It, Hero!/Only I Can Kill Him: While they were still Enforcers, Jake and Chance had Dark Kat's ship cornered. Unfortunately, Feral insisted on capturing the villain personally, and his interference resulted in Dark Kat escaping, Enforcer headquarters being damaged, and Jake and Chance getting thrown off the force—and deciding to become the SWAT Kats.
- Staff of Authority: He's often seen carrying around a gold-handled baton.
- Teeth-Clenched Teamwork: He frequently clashes with Manx and Briggs, and he's openly contemptuous of Steel.
- Top-Heavy Guy: Bulky upper body, stick-thin legs.
Mayor Manx may have the title, but Callie, his attractive young troubleshooter, is the one who really runs Megakat City. (Which is a good thing, considering how lazy and incompetent Manx is.) She's also the SWAT Kats' most powerful ally, although the TV series never revealed how their friendship started. Callie has a secret communications link with the SWAT Kats that allows her to call them into action, and she defends the heroic pilots whenever Commander Feral criticizes them. Callie copes with danger better than Manx or Feral, because she's braver than Manx and smarter than either of them.
Tropes associated with Callie:
- '80s Hair: Callie's hair is huge. It's as big as her head.
- Action Survivor: She may be a civilian, but when there's trouble she always rises to the occasion.
- Badass Bureaucrat: When the occasion calls for it. She hates being a Damsel in Distress, and regularly takes steps to become a Badass Damsel instead.
- Briefcase Blaster: In "The Dark Side of the SWAT Kats", her Evil Counterpart in the Mirror Universe has a briefcase with the capacity to shoot out Knockout Gas.
- The Commissioner Gordon/Regular Caller: Callie alerts the SWAT Kats whenever a supervillain or giant monster is making trouble in Megakat City.
- Cry Cute: During episode "Katastrophe", Dark Kat manages to destroy the Turbo Kat, believing that he finally killed the Swat Kats. For the end of that sequence, she's shown in shock and some tears start to roll down her eyes.
- Demoted to Extra: If you don't count the unfinished episodes, her appearances during second season could be counted with the fingers of one hand. This obviously happened due to the inclusion of Felina Feral, who being an Action Girl, had a more active role than Callie.
- The Dragon: In a Mirror Universe, Callie is a corrupt politician of the first order, manipulating the mayor to maintain her hold over the city.
- Geeky Turn-On: Brains, beauty, courage and compassion—what's not to like?
- Girl Friday/Hypercompetent Sidekick: To Mayor Manx. Even though nobody ever says it out loud, it's accepted by the people of Megakat City that she's the one they need to be looking up to.
- Hair of Gold, Heart of Gold: Callie has this, being the kind of person to put her own needs on hold before her duty to her city.
- The High Queen: In an Alternate Universe, she's the queen of the land instead of deputy mayor, named Calista.
- Improvised Weapon User: She becomes one during her Let's Get Dangerous! moments. In "Night of the Dark Kat", she saves the SWAT Kats by hitting the eponymous villain with one of the money bags he'd stolen. In "The Ci-Kat-A", when alien-possessed scientist Dr. Harley Street is trying to "recruit" her, Callie says "I don't think so!" and smashes him on the head with her briefcase.
- Oblivious to Love: On both ends of this. On one hand, she is unaware that Chance has feelings for her, and only considers him a friend. On the other, it's implied she is at least attracted to Jake, given a send off.
- Only Known by Their Nickname: As noted above, Callie's full name is Calico Briggs. It's only used occasionally.
- Reasonable Authority Figure: In marked contrast to Manx and Feral.
- She's Got Legs: Does she ever, the Fandom in particular seems obsessed with Callie's legs.
- The Woman Behind the Man: A rare heroic example. She's only the deputy mayor, but Mayor Manx being actually in control terrifies everyone who knows the both of them.
- Silk Hiding Steel: Despite only being Manx's assistant, if she wants something done, then the mayor will find himself doing it. Also, as noted above, she can handle herself in a fight.
Introduced in the second season, Felina is a gung-ho Enforcer who happens to be Commander Feral's niece. Her uncle tries to keep her out of danger, but this feisty warrior woman insists on storming into the thick of each battle. Like Callie, Felina realizes that Megakat City needs the SWAT Kats and is willing to work with them.
Tropes associated with Felina:
- Affirmative Action Girl: She was added in Season 2 so there would be more girls in the cast. Felina actually carries a gun and involves herself in the fighting as a matter of course, leading squads of Enforcers against whatever is currently threatening Megakat City.
- Alliterative Name: F and F.
- Determinator: She often won't take no for an answer and won't stop until she's accomplished whatever task she has set herself to. Provided, of course, it is still possible for her to do so. If not, she Knows When to Fold 'Em.
- Fair Cop: Compared to her uncle, she is a little more openminded and accepting of the SWAT Kats. She is also never rude or disrespectful to anyone, and never abuses her authority.
- Friend on the Force: To the SWAT Kats.
- The Lad-ette: To date, she is the only female Enforcer.
- Skunk Stripe: She has white sideburns for... some reason.
- Tomboy: While female, she has a hard jawline and prominent cheekbones, giving her a somewhat boyish appearance, and in addition, she dresses in a men's (or at least unisex) uniform and does stereotypical masculine things like shoot laser guns, fly helicopters and shoot monsters and bad guys. The one feminine thing she's ever shown doing is fixing her hair after taking her helmet off in "When Strikes Mutilor," 'cause no one wants helmet hair.
Feral's other second in command. Steel(e?) is an arrogant and inexperienced officer who wants Feral's job, but doesn't want to have to actually work to earn it. In his first appearance ("The Wrath of Dark Kat") he actually betrays Feral in an effort to get him killed by Dark Kat so he can become the commander. Somehow, Feral lets him stay, and he appears one more time (in "Enter the Madkat") to (legally) take over Feral's job when Feral is captured by Madkat. His performance in this capacity consists of sitting on his butt and dismissing people out of hand.
Tropes associated with Steel:
- Arbitrary Skepticism: Despite living in a world that regularly features supervillains, giant monsters, mutations and magical phenomena, when Katzmer (the antique store owner) tries to warn him about Madkat, Steel dismisses him as a crank immediately.
- Chronic Back Stabbing Disorder: Averted. He only betrays Feral to take over the Enforcers once. The second time he gains control, he was simply an opportunist taking advantage of Feral's capture (and technically doing his job as lieutenant commander, since he was next in command).
- Ironic Name: His name is Steel, but his nerves are anything but when faced with actual combat. The only linked meaning to his name is that he's incredibly dense like steel as he is totally incompetent at his job.
- The Neidermeyer: He is quite incapable of running anything, much less the Enforcers; in his second appearance, he basically just sits at Feral's desk and ignores robbery complaints.
- Not-So-Badass Longcoat: Like Feral, he wears a greatcoat, but it doesn't do much for him in the "badass" department.
- Police are Useless: Is probably the most useless officer on the force despite his rank. He's basically an enforcer in name only, only wanting to command people to do his bidding, but when faced with actual combat, he chickens out.
- Professional Butt-Kisser: Prior to betraying Feral, he compliments him incessantly. He reverts back to this mode after his betrayal is uncovered.
- Put on a Bus: He doesn't appear or even get mentioned in the second season. Instead, his role as Feral's second in command is filled by Felina. One wonders what ultimately became of him. Most likely, Feral finally got tired of his antics and fired him.
- Spell My Name with an "S": In "The Wrath of Dark Kat," he insists his name his Steel "with two E's," but when we see his nameplate in "Enter the Madkat," it says Steele with three E's. Nobody is quite sure which is the correct spelling. Not even Steel(e) apparently.
- According to the storyboards for "Enter the Madkat," it is in fact Steel with two Es, and his nameplate was supposed to say "Steel", but it appears the animators screwed up.
- The Starscream: A rare example where the character wants to take charge of a heroic organization. That said, Steel isn't very heroic and is more interested in giving orders.
- Welcome Back, Traitor: For some reason, he's not only still in the Enforcers, but still the lieutenant commander in "Enter the Madkat", despite the fact Feral knows Steel basically abandoned him to get killed.
Tough, capable, humorless Enforcer officer. When Felina isn't around, it's usually this guy who acts as Commander Feral's right-hand man.
Tropes associated with Sergeant Talon:
- All There in the Script: His name is given in the script for "Destructive Nature." On his model sheet, he's simply called Enforcer Sergeant.
- One Steve Limit: Averted. There's also a prison guard named Talon in the episode "Chaos In Crystal."
- Out of Focus: He never disappears entirely like Steel, but only actually has speaking roles in two episodes in season two (one of which is a Whole Episode Flashback). His role is mostly supplanted by Felina, with him reduced to just sort of being "there."
- The Quiet One: He rarely speaks except to growl out orders.
- Reused Character Design: With one exception, the other generic Enforcer sergeants reuse his character design. This sometimes makes it difficult to tell if it's Talon or not (although a good rule of thumb is that if it's voiced by Ed Gilbert or Jim Cummings, it's Talon).
- Sergeant Rock: He's a pretty tough, sturdy kat and holds the rank of sergeant.
- Undying Loyalty: To the Ferals.
The warden of the Megakat Maximum Security Prison.
Tropes associated with Warden Meece:
- All There in the Script: His first name isn't mentioned in the episode, only in the script and on his model sheet(s).
- Asshole Victim: His exploitative practices come back to bite him in the ass when one of his prisoners suffers a horrible accident and goes on a murderous rampage.
- Corrupt Corporate Executive: He makes all the profits from the diamond mining by his prisoners and gives no care to their well-being in return.
- Corrupt Hick: Given his Southern accent.
- Fatal Flaw: He shares the same kind of greed Rex Shard has, but it's Meece that pays the price for it, whereas Shard at least gets a second chance in life at prison once he's de-crystallized.
- Informed Attribute: His greediness, aside from a couple of lines of dialogue alluding to it, although this is mostly a case of We Hardly Knew Ye due to SWAT Kats not being particularly plot-heavy.
- Insistent Terminology: He calls his mining operations a "volunteer work program," even though the prisoners get nothing in return for their "work."
- Killed Off for Real: Most of the denizens, including Rex Shard, are seen reverting back to their normal selves after Shard is de-crystallized. Meece? Probably not.
- Literally Shattered Lives: Courtesy of Dr. Greenbox. He's the only victim of Shard's rampage to shatter on-screen.
- Nice Job Breaking It, Hero!:
- His decision to rely on a mining machine that hadn't received proper testing ultimately resulted in Rex Shard's accident.
- Meece's own death is because of Dr. Greenbox clumsily not looking behind him when Rex breaks free from the SWAT Kats' cement balls and thus knocking the crystallized warden over.
- No Celebrities Were Harmed: He's intended to basically be a feline M. Emmett Walsh.
- Punny Name: "Cyrus Meece" = "Siamese," even though he clearly isn't a Siamese cat.
- Taken for Granite: He's the third victim of Rex Shard's crystal touch.
- Unwitting Instigator of Doom: It was Meece who authorized the use of the untested Gemkat 6000 that played a role in Rex Shard's accident and subsequent rampage.
- We Hardly Knew Ye: Gets a few scenes before dying.
Enforcers outfitted in riot gear and armed with laser rifles. They serve as everything from infantry to tank crews and perform the extremely dangerous (and often thankless) job of protecting Megakat City from harm.
Tropes associated with the Commandos:
- New Meat: A rookie commando appears in "Night of the Dark Kat." He insists he sees something but his sergeant laughs it off. Turns out he was Properly Paranoid, as Hard Drive breaks into the facility they're guarding immediately afterward.
- One-Way Visor: Their helmets feature opaque blue visors that hide their eyes. Two were (very briefly) seen without them in "Mutation City," however.
- Red Shirt Army: Their duties frequently put them in harm's way, and, being nameless soldier types in an action cartoon, they typically come to bad ends.
- Reused Character Design: As noted on their model sheets, they're all the exact same character design recycled multiple times to create a big army at minimal cost to the animators.
Exactly What It Says on the Tin. Multidisciplined aviators who fly the Enforcers' jets and helicopters, often answering Feral's pleas for "chopper backup." When they were still in the Enforcers, this is what Chance and Jake were.
Tropes associated with the Pilots:
- Early Installment Weirdness: Burge and King were apparently intended to be Those Two Guys among the Enforcers, but were dropped after two episodes.
- New Meat: The unfinished episode "The Doctors of Doom" gives us Felina's rookie partner Gray Taylor. He comes to a bad end.
- One-Way Visor: Like the commandos, their helmets have opaque visors. Two of them were seen without them in "The Ci-Kat-A," but this was only so we could see their eyes turn insectoid when the title creatures bite them.
- Pre-Mortem One-Liner: In "The Pastmaster Always Rings Twice," when Burge asks his partner King if they ought to read the living skeletal zombies "their rights," King replies that they have "the right to remain buried," and promptly blows them away.
- Red Shirt Army: Arguably moreso than the commandos, considering how many jets and choppers eat it in the series. Occasionally, though, we'll see a pilot parachuting to safety.
- Mauve Shirt: Sgt. Gray Taylor in "The Doctors of Doom," one of the episodes left unfinished when the series was cancelled. Introduced as Felina's new partner, he's a hotshot rookie pilot fresh from the academy with a full name and backstory. Not only is he bitten by a Ci-Kat-A and turned into a drone, Dr. Viper later mutates him into a giant grub worm and he's killed in battle with the SWAT Kats.
- Reused Character Design: Again, like the commandos, they all look identical to one another as a cost-cutting measure, something stipulated on their model sheets.
This Kat's Eye News correspondent often risks her life to cover the SWAT Kats' adventures.
Tropes associated with Ann:
- A Day in the Limelight: Ann gets more important roles than usual in "The Ci-Kat-A" and "Caverns of Horror".
- Fiery Redhead: She's got auburn hair and is pretty feisty in a laid-back kinda way.
- Going for the Big Scoop: Ann possesses an indomitable desire to get to the bottom of any mystery presented to her. Unfortunately, her enthusiasm and ambition often outweigh her common sense, resulting in her getting herself and her Kat's Eye News colleagues into trouble more than once.
- Intrepid Reporter: Ann's efforts have helped blow the lid on quite a few big stories. She and Jonny uncovered an alien Assimilation Plot while on a routine visit to MASA (although at least part of that was the possessed people giving themselves away too soon), setting in motion the events which saved the city and possibly the world, and although it went south pretty quickly and required her to be rescued by the SWAT Kats and Felina, she did discover the fate of five missing miners, probably giving their friends and families closure.
- Ms. Exposition: Ann's reports are often used to bring the audience up to speed on the plot.
- Punny Name: Her name is pun on "Angora", a breed of domestic cat.
Jonny is the faithful but longsuffering Kat's Eye News cameraman. Almost always seen with Ann, Jonny is more cautious than her but rarely speaks out against her ideas, which typically get her into trouble - and sometimes him right along with her!
Tropes associated with Jonny:
- Action Survivor: He is frequently involved in action scenes but never does anything heroic, really.
- Affectionate Nickname: The only one who gets away with calling Ann Gora "Annie"
- All There in the Manual: The initial "K" is only mentioned on the model sheets.
- Butt-Monkey: Bad things tend to happen to his video camera.
- Cool Shades: Mirrored purple sunglasses.
- First-Name Basis/Mysterious Middle Initial: Just what does the "K" stand for, anyway?
- Real Men Wear Pink: Well, okay, purple, but still.
- Suddenly Voiced: Although he utters a small cry of surprise in "Chaos in Crystal," it wasn't until "The Ci-Kat-A" that he finally spoke.
- Sunglasses at Night: Except for "Caverns of Horror", he always has his sunglasses down over his eyes, even in nighttime scenes.
- Surfer Dude: He has some elements of this, given the era of the show.
- Totally Radical: His voice and some of the things he says root him pretty permanently in the early 90's.
- Undying Loyalty: To Ann.
A historian and archaeologist who works as the curator of the Megakat City Museum of History. She occasionally helps the SWAT Kats and Callie Briggs gather information on supernatural villians.
Tropes associated with Abby:
- Adventurer Archaeologist: In her first two appearances, she is only ever seen in and around the museum. However, in "The Deadly Pyramid", she's shown out on a dig searching for the lost pyramid of the title.
- Brainy Brunette: She has brown hair and is definitely the person to go to whenever something weird and supernatural is going on. And if she doesn't know something off the top of her head, she looks it up.
- Lab Coat Of Science And Medicine: Often with the collar turned up.
- Punny Name: Her name is a play on the Abysinnian breed of cat.
- Spell My Name with an "S": Is it "Abby" or "Abi"?
- Abby, going by one model sheet, although it's annoyingly mostly illegible due to the Cartoon Network logo.
- The scripts for "The Pastmaster Always Rings Twice" and the unfinished episode "Succubus!" (where she has an important supporting role) and the book The Art of SWAT Kats, which includes scans of pages from a story outline for "The Deadly Pyramid," give it as Abby.
An elderly inventor who used to work at the Pumadyne weapons lab. He came to feel guilty about his role in creating superweapons, so he quit to concentrate on peaceful projects, such as bringing back dead people by transferring their memories into robot bodies. When two drowning victims washed up near his home, he used them as test subjects—only to realize that he'd created the Metallikats. Hackle hopes to correct this error by recapturing the robot gangsters so he can "program out all [their] criminal tendencies". Hackle's other inventions include Cybertron, the Robot Buddy who assists the SWAT Kats in "The Deadly Pyramid".
Tropes associated with Professor Hackle:
- Actual Pacifist: Which is why he doesn't just dismantle the Metallikats when he gets a chance.
- The Atoner: Hackle says that he wants history to forgive him for creating superweapons. And after "The Metallikats," he now feels he has the title villains to atone for unleashing, as well.
- Bald of Awesome: He is a pretty awesome scientist with male-pattern baldness.
- Classy Cane: Due to his age, he walks with one in almost all of his scenes.
- Cool Old Guy: He is a Gadgeteer Genius who invents all kinds of cool things, including a Robot Buddy for the SWAT Kats.
- Labcoat of Science and Medicine: He wears your standard white lab coat.
- Last-Name Basis: His first name is never revealed, even on his model sheet.
- Nice Job Breaking It, Hero!: Hackle's creation of the Metallikats shows that he is, at the very least, a dangerously naive victim of Genre Blindness. Never mind his using two strangers in prison uniforms as test subjects; he was trying to save their lives, after all. But then he leaves them alone with a Weaponized Car and a cache of arms, even after Mac says "I've never felt so powerful, like I could rip apart this town with my bare claws!"
- In his defense, he later admits It's All My Fault and in the alternate future in "A Bright and Shiny Future" where Mac and Molly have taken over the entire city, he blames himself for not dismantling the Metallikats when he had the chance.
Cybertron is a friendly, helpful little robot designed by Professor Hackle after his many failures to rehabilitate the Metallikats. He is intended as a gift to the SWAT Kats in repayment for the many times they've helped him. He proves a valuable ally against the Pastmaster's army of giant mummies in "The Deadly Pyramid", performing many heroic acts. Not to be confused with the planet of the same name.
Tropes associated with Cyberton:
- An Arm and a Leg: He loses his left arm fighting the mummies.
- Beware the Cute Ones: Yes, he's a cute little catlike robot... but he's also a very formidable fighter with a lot of surprises in store for anyone who might underestimate him. He's still no match for the giant mummies, though.
- Brainwashed and Crazy: In "Turmoil 2," Turmoil reprograms him to work for her. Razor eventually turns him back to the good side, though, by undoing the reprogramming.
- The Determinator: Nothing short of death (or at least being severely damaged) will stop him from completing an assigned task. When two giant mummies attack after he's been told to protect Callie, Dr. Sinian and Henson, Cybertron endures a lot of punishment while refusing to give up. No matter what the mummies do to him, he keeps getting up and coming back for more.
- Hanging by the Fingers/Literal Cliffhanger: At the end of "Turmoil 2," he's literally hanging by his fingers from a cliff edge. Turmoil attempts to make him fall by stepping on his fingers ("Termination time, tin man!"), but he's saved by T-Bone.
- Heroic Sacrifice: He pretty much dies defending Callie and the others from the mummies. The damage he sustains during the fight causes him to eventually just stop working. He's rebuilt in "Turmoil 2: The Revenge.
- Robot Buddy: Designed as one for the SWAT Kats.
- Senseless Sacrifice: Debatable. Callie still gets abducted, but his actions do at least save the lives of Dr. Sinian and her assistant Henson, and he remains functioning long enough to (somehow) get word to the SWAT Kats that Callie's been taken.
- The Speechless: He communicates solely in beeps and boops and other robot type noises.
- Taking the Bullet: Well, laser. When a mummy aims at Callie, Sinian and Henson and fires, Cybertron puts himself between the shooter and his targets, taking the full force of the mummy's laser blast. It's this and being thrown into a wall a moment or two later that finally does the little Determinator in.
- Uncertain Doom: He pretty much shuts down after all the damage he takes. Although he's a robot and can be rebuilt, the episode ends before this can take place, leaving Cyberton's final fate up in the air. However, he was scheduled to return in the unfinished episode "Turmoil 2: The Revenge".
- In said episode's script, he helps Razor out against Turmoil's forces despite being briefly reprogrammed to serve her. He survives the end of the episode.
Burke and Murray are two annoying delivery men who bring salvage to Jake & Chance's Garage, always taking a moment to pester Clawson & Furlong about their status as officially disgraced ex-Enforcers.
Tropes associated with Burke and Murray:
- All There in the Manual: Early promotional material says they're brothers, but this isn't mentioned in the show.
- Big Guy, Little Guy: Burke is basically a big oval with arms and legs, while Murray is essentially a midget.
- Fat Idiot: Burke is big, fat and not terribly bright.
- First-Name Basis: We never learn their last name.
- The Friend Nobody Likes: And it's mutual. They don't like Chance and Jake and Chance and Jake don't like them, but due to proximity (i.e., they also work at the salvage yard and are tasked with supposedly babysitting them), they're sort of stuck with each other.
- Jerkasses: Their greatest joy in life is tormenting Chance and Jake and attempting to pick fights with them for no apparent reason.
- Put on a Bus: They don't appear in the second season.
- Those Two Guys: They're always hanging around the salvage yard and being a pain.
A kindly scientist who works at Megakat Biochemical Labs and was once Dr. Viper's employer. A gentle but forgetful soul, Zyme wanted nothing more than to make the world better for katkind. Instead he inadvertently created Dr. Viper, and like his counterpart, Professor Hackle, saw his dreams turn into a nightmare. In "The Giant Bacteria," he tried to assist Feral in battling Viper's bacteria monsters and (probably) got eaten by one of them.
Tropes associated with Dr. Zyme:
- Absentminded Professor: He's prone to forgetting his reading glasses, to the point of searching nonexistent pockets for them.
- Adorkable: It's hard not to like his enthusiasm when telling Purvis to think of all the good the Viper Mutagen will do, and when telling Manx about it over the phone.
- All There in the Script: His first initial "N," which creates his Punny Name, is given in his episode model sheets.
- Death by Looking Up: When the bacteria monster smashes the lab window in "The Giant Bacteria," Zyme stands there looking up and screaming instead of running away (as Callie did).
- Distressed Dude: Gets tied up in two different scenes in "The Origin of Dr. Viper."
- Hartman Hips: He has a very hourglass-shaped figure for a guy, making him a Rare Male Example.
- Lab Coat Of Science And Medicine: The old-timey kind with the very high collar that buttons off to one side.
- Mysterious Middle Initial: We have no idea what the "N." stands for.
- Nice Job Breaking It, Hero!: Played with. His and Purvis' flawed plant growth formula are what turn his greedy partner into Dr. Viper, dooming Megakat City to a neverending stream of hackneyed Mad Scientist plots and even (probably) getting poor Zyme himself Killed Off for Real. Oddly, he never blames himself for it, or has the finger pointed at him by anyone. Commander Feral even flat-out tells him, "It wasn't your fault, Dr. Zyme."
- Punny Name: "Enzyme."
- Red-Headed Hero: He's a very noble scientist working for the good of all and has auburn hair.
- Uncertain Doom: Word of God aside, "The Giant Bacteria" never really confirms whether the bacteria monster got him or not.
An inventor who was originally hired by Warden Meece of the Megakat Maximum Security Prison to design a diamond-mining machine. It's what turned convict Shard into a crystal monstrosity. Later, he developed a "micro-brain repair unit," which the Metallikats stole and used to repair themselves. It then became "Zed," a sentient giant robot, which Greenbox... for some reason... suddenly decided to help destroy Megakat City.
Tropes associated with Dr. Greenbox:
- FaceHeel Turn: After he realizes he inadvertently helped create actual artificial intelligence, he becomes a generic Mad Scientist and turns against the SWAT Kats.
- Go Mad from the Revelation: This seems to be the only workable theory for why he suddenly goes nuts and decides to start helping Zed.
- Lab Coat Of Science And Medicine: Only in "Unlikely Alloys." In "Chaos in Crystal," he goes in just a shirt and tie (and pants, of course).
- No Celebrities Were Harmed: The script for "Chaos in Crystal" describes him as resembling Woody Harrelson in appearance and demeanor.
- Non-Indicative Name: His name "Greenbox" (i.e. greenhouse) is an artifact of how writer Lance Falk originally intended to use him, as a botanist. When his profession changed, his name didn't.
- Punny Name: Falk gave him the first name "Lieter" to turn his name into some kind of weird play on "litterbox," which makes even less sense. It's also a Shout-Out to the James Bond character Felix Leiter.
- Apparently it's a reference to a specific brand of cat litter, Litter Green.
- Although the pronunciation is different and there's some disagreement over how Greenbox's first name is spelled. See below.
- Spell My Name with an "S": Is it "Lieter" or "Leiter?" A sketch of him in his lab coat from "Unlikely Alloys" calls him "Leiter Greenbox," although this surely would mean his first name is pronounced like "Lighter," whereas it's said like "Liter." Then again, names aren't always pronounced how they're spelled so maybe it is "Leiter." There's also the possibility that whoever jotted the name down just mixed up the I and E.
- Taken for Granite: He got turned to crystal by Shard. He got better after the SWAT Kats reversed everything Shard had done.
- Unexplained Recovery: Twice. First after he's returned to his normal state along with everyone else Shard crystallized, and again after T-Bone severs the connection between him and Zed, and he just sort of acts mildly worn out. Which leads to:
- What Happened to the Mouse?: Well, cat. "Unlikely Alloys" ends before really going into what, if any, action will be taken against him, or even if the SWAT Kats will tell anyone he was the one who had Zed get the Mega-Beam and use it to blow up the mountain and almost destroy Megakat City.
- Word of God says he's "in the nuthouse."
The ruler of Megalith City, Megakat City's medieval predecessor, during the Dark Ages. She looks similar to Callie Briggs and is her ancestor.
Tropes associated with Callista:
- All There in the Script: Her being Callista's ancestor is never actually stated in either "Bride of the Pastmaster" or "The Deadly Pyramid." Everyone (including the Pastmaster) just assumes it. However, her model sheet for "Bride of the Pastmaster" explicitly identifies her as "Callie's ancestor."
- Amulet of Concentrated Awesome: The green gem she wears around her neck and seems to be the source of her powers (although she can perform magic without it). It is capable of firing painful Frickin' Laser Beams that incapacitate enemies. Too bad one of the Pastmaster's harpies crushes it.
- All Heroes Want Blondes: Razor is pretty smitten with her. T-Bone, despite his obvious interest in her descendent Callie Briggs, doesn't seem to like Callista "that way," and ribs his partner about his crush on the Queen.
- Everyone Loves Blondes: The Pastmaster is pretty smitten with Callista, too.
- Benevolent Mage Ruler: She has magic powers and is a kind and just ruler.
- Bring It: This seems to be her main motivation for accompanying her guards into battle. She knows it's her the Pastmaster wants, not her subjects, so she probably wants to draw him out. Unfortunately for her, he refuses to play her game, sending monsters in his stead.
- Damsel in Distress: She gets kidnapped by two creatures (identified in the model sheets as "harpies," even though they just look like tiny dragons) and taken to the Pastmaster's tower to be forced to marry him. May also count as Badass in Distress, since she isn't exactly a pushover.
- Frontline General: She often personally goes into battle along with her guards.
- Generation Xerox: An inversion.
- Literal Cliffhanger: She almost falls off of a cliff while fleeing from the cyclops, but her chief guard Tabor pulls her up.
- Reasonable Authority Figure: Although she does (for some reason) initially mistake the SWAT Kats for allies of the Pastmaster.
- Royals Who Actually Do Something: One thing Callista is never shown doing is sitting on a throne or even in her throne room, period. Instead, she goes out on scouting parties with her guards and personally participates in fights.
Three Siamese businessmen who often deal with Mayor Manx. Their various efforts typically end badly, although they did finally successfully open the Anakata Island Park together.
Tropes associated with Young:
- Asian Buck Teeth: The tall businessman has them, as seen in "Volcanus Erupts!"
- Big, Thin, Short Trio: Sort of. The thinnest is the tallest, while the fattest is the shortest. Young is of medium height and build. They're more like "Tall, Average and Short Trio."
- Camera Fiend: During the development of the Anakata Island industrial park, the tall businessman is seen taking pictures of everything around him.
- Covered in Gunge: In "The Ci-Kat-A", Young, Manx and their chauffeur get splattered with alien bug guts at the end.
- Fat and Skinny: The tall businessman is very thin in addition to his height. The fat businessman's name speaks for itself.
- Honest Corporate Executive: Young deals fairly with Manx. Also, during their attempt to build an industrial park on Anakata Island, he is the only one between him and Manx who wants to respect the natives' culture by relocating, rather than bulldozing, the sacred Talisman Stone.
- Inscrutable Oriental: To an extent.
- Japanese Politeness: Although Young isn't Japanese (Japan doesn't exist as such in the SWAT Kats universe), he and his partners are obviously based off of Asian businessman stereotypes, including this; they're very polite, even when telling Manx they're no longer interested in whatever he's offering them.
- No Name Given: The other businessmen. Even writer Lance Falk has stated that they're just called "two silent associates" in the script for "Destructive Nature." In the show, they're only ever referred to as Young's "associates" ("My associates and I..." etc.).
- Satellite Character: The other two businessman, who never say anything or contribute anything meaningful to the plot. They're just sort of "there."
- Sharp-Dressed Man: They wear nice business suits.
- The Voiceless: Apart from one scene where they confer with Young in whispers, the other two businessmen never speak.
Al is the Kat's Eye News helicopter pilot.
Tropes associated with Al:
- Action Survivor: He's just trying to do his job and fly the news helicopter.
- Chronically Crashed Car: The news helicopter, although through no fault of Al's.
- Mauve Shirt: His name is only mentioned once and he's barely even a supporting character, and unlike Ann and Jonny he hasn't got Plot Armor.
- Properly Paranoid: In "The Wrath of Dark Kat," he objects to Ann's demand that he fly closer to the Fear Ship, and she considers him a wimp. When he finally gives in and flies closer, they get shot down. In "Night of the Dark Kat," he flat out refuses to go anywhere near the hijacked Turbokat because it just shot down what looked like a hundred Enforcer choppers.
- Put on a Bus: Although the news copter appears many times, Al isn't seen in the second season.
- This is especially egregious in the episode "SWAT Kats Unplugged," in which we see a partial interior of the helicopter but the pilot's seat is completely empty.
Dark Kat is a criminal mastermind whose muscular body, hood, cape, and resonant voice give him an imposing physical presence. He specializes in plotting, scheming, and manipulating others into doing his will, but is more than capable of fighting when necessary. Dark Kat's goal is to destroy Megakat City and replace it with a "capitol of crime" called Dark Kat City, "where lawlessness is the law of the land!" His henchmen are an army of demonic little bat-like creatures called Creeplings.
Tropes associated with Dark Kat:
- Barefoot Cartoon Animal: Like Dr. Viper, he never wears any shoes. Probably because his feet are so darn huge. In addition, in some scenes, it's possible to see his bare thigh through the part in his robe, suggesting he doesn't wear pants.
- Black Cloak: He wears an impressively villainous-looking hooded black cloak with red trim over a gray robe, with a big metal pauldron bearing his stylized "D" emblem.
- Blank White Eyes: He has solid yellow eyes without pupils.
- Big Bad: Arguably the most powerful and ambitious villain in the entire series.
- Big "NO!": As befitting his status as the SWAT Kats' arch-enemy, Big D is fond of crying "Nooooo!" whenever he gets defeated (most notably in "Katastrophe" when he gets trapped in his own forcefield bubble).
- Bomb Throwing Anarchist: Essentially his goals in a nutshell. Wants to cause chaos and turn Megakat City into a lawless nightmare, or just wants to flatten it.
- Bond Villain Stupidity: In "Night of the Dark Kat", he chooses to simply strap the Swat Kats to a Conveyor Belt o' Doom and leave them to die while he and Hard Drive go about their plan. Hard Drive even remarks that Dark Kat should have just let him fry them.
- Card-Carrying Villain: As noted. His ultimate goal is to destroy Megakat City and replace it with his "capitol of crime" Dark Kat City.
- Classy Cane: He often carries a walking stick, although he doesn't seem to need it.
- Cool Plane: His "Doomsday Express" (actually revealed to be called the Fear Ship in behind-the-scenes materials).
- Diabolical Mastermind: If there's any kind of complicated, nefarious scheme afoot in Megakat City, Dark Kat is usually the one behind it.
- Evil Plan: Like any good villain, he uses one or more on the list in his quest to ultimately destroy Megakat City.
- Evil Sounds Deep: Considering he's voiced by Brock Peters, it isn't surprising he's got probably the deepest voice in the entire series.
- Flaw Exploitation: Part of his plan in "Razor's Edge". He tricks Razor into thinking that he injured two elderly civilians, knowing his guilt would cause him to quit crimefighting.
- Glass Cannon: He is very big and physically powerful, but is remarkably easy to take out with only one or two punches or kicks.
- In the Hood: Although his face is visible, his neck isn't. His head basically appears to simply be floating inside of his hood.
- Mighty Glacier: Although he is usually The Unfought despite his immense size and great physical strength, when he does involve himself in battle, it's as this.
- Large and in Charge: He's the SWAT Kats' mortal enemy, and he's even bigger than Commander Feral.
- Large Ham: Although he's usually presented seriously, he has his moments of villainous ham and scenery-eating.
- Purple Is Powerful: He has purple fur and is a very powerful villain.
- Shrouded in Myth: Is the only member of the Swat Kats' rogues gallery not to be given a definite backstory. (Promotional material for the series stated that by day, he was a Megakat City judge that helped keep his true life well-hidden, but this wasn't referenced in-show.)
- To Create a Playground for Evil: His ultimate goal is to turn Megakat City into Dark Kat City, a "capital of crime."
- Unexplained Recovery: Is shot down in his ship in "The Wrath of Dark Kat," seemingly being killed, but is back again just fine in "Night of the Dark Kat." Then at the end of "Katastrophe," he blows himself, Dr. Viper and the Metallikats up rather than admit he'd lost, but once again returns just fine in "Razor's Edge."
- Villainous Valor: In "The Wrath of Dark Kat," when he is caught in a net by Razor and his Creeplings are trying to free him, he tells them to forget about him and carry on with the mission: "Nevermind me! Load the bomb!"
- Visionary Villain: He wants to destroy the city and rebuild it as his own Egopolis: "Dark Kat City."
This slimy scientist (and walking biohazard) started out as Elrod Purvis, a greedy, unscrupulous biochemist. When he tried to steal Viper Mutagen 368 from the idealistic colleague who had co-created it with him, the formula killed him, then revived him as a half-kat/half-reptile monstrosity—and he likes it that way. To make his twisted dream of Megaswamp City a reality, Viper mutates ordinary plants, reptiles and insects into hideous, kat-eating monsters under his control.
See the section on Dr. Harley Street for more info one Viper's appearance in one of the three unfinished episodes, "The Doctors of Doom".
Tropes associated with Dr. Viper:
- Attack of the 50-Foot Whatever: He temporarily becomes a giant in "Mutation City".
- Back from the Dead: Was reanimated by the chemical that splashed on him and killed him in the first place.
- Blank White Eyes: He has solid yellow eyes without pupils.
- By the Lights of Their Eyes: How he's frequently introduced, including in his very first appearance.
- Came Back Wrong: Of course, he wasn't exactly a decent man to begin with.
- Chronic Backstabbing Disorder: Not only does he betray and mutate Morbulus in "The Giant Bacteria," he also betrayed Dark Kat in "Katastrophe" (but only because he anticipated Dark Kat's own betrayal of him), and in "The Doctors of Doom" he would've turned against Dr. Street, turning him and the other Ci-Kat-A into hideous mutants to do his bidding. Protip: Don't ally yourself with Dr. Viper.
- Even before becoming Viper, he betrayed his employer Dr. Zyme pretty much instantly.
- Deceptive Disciple: He started out as Dr. Zyme's assistant, and then betrayed him to try and steal his life's work.
- Evilutionary Biologist: Hell. Yes.
- From Nobody to Nightmare: From a mere lab assistant to one of the most dangerous villains to plague Megakat City.
- Glowing Eyes of Doom: More than any of the other villains, probably. Usually seen when he's in a dark or shadowy environment.
- Half-Dressed Cartoon Animal: He's usually wearing only a lab coat and nothing else.
- Labcoat of Science and Medicine: Albeit one that appears to be several sizes too large for him.
- Lantern Jaw of Justice: He could do gardening with his enormous, spadelike chin!
- Laser-Guided Karma: The only reason he got mutated is because he tried to steal the mutagen.
- Mad Scientist: According to the "Secret Files of the SWAT Kats," little fact files which sometimes were shown at the ends of certain episodes, his actual occupation is "Evil Biochemist."
- Manly Tears: Just the thought of transforming Megakat City into a swampy nest of mutants made tears roll from his eyes during "Destructive Nature".
- Mix-and-Match Critter: Half-kat, half-snake.
- New Powers as the Plot Demands: As a result of mutating himself (further!) into a giant monster in "Mutation City", he gains the ability to shoot acid out from under his fingernails. Although he would've been returned to normal (for a given definition of "normal") by the anti-mutagen blast at the end, "The Doctors of Doom" would've revealed he kept the acid fingernail ability.
- Never My Fault: While trying to run away with a stolen sample of the Viper mutagen, Purvis lets the bottle break and blames Dr. Zyme for making him do it.
- Only in It for the Money: He tried to steal the Viper mutagen purely to sell it for money.
- Prehensile Tail: Multiple times in the series, he can use his long, snakelike tail to grab objects and people.
- Snake Talk: If there's an "S" in a sssentence, expect Dr. V to draw it out. Ssss!
- That Man Is Dead:Dr. Zyme: Is that you, Purvis?Dr. Viper: Not anymore! Just call me Viper. Doctor Viper. (cackles)
- Unexplained Recovery: He survives no less than three gigantic explosions in as many episodes, and keeps coming back.
- Visionary Villain: See his quote above.
- We Will Meet Again: As he escapes at the end of "The Origin of Dr. Viper", he promises that "You haven't seen the last of Dr. Viper!"
- What Happened to the Mouse?: He isn't seen again after "Mutation City," his next appearance being a flashback episode. He would've returned in season two's finale, "The Doctors of Doom," returned to his original "normal" mutated state, wherein he would've teamed up with (and later betrayed and mutated) Dr. Harley Street.
Dr. Viper's hulking half kat, half mushroom assistant.
Tropes associated with the mushroom monster:
- Blank White Eyes: He has solid eyes without pupils, just like his creator. They're a faint pinkish color.
- Cephalothorax: Enormous in size, he hasn't got a body to speak of, just a big, mushroom cap head with cat ears and tentacles. And a really huge mouth.
- Combat Tentacles: Several of them, although he has two "main" ones he uses for "arms." The others appear to be merely for locomotion.
- Extreme Omnivore: He'll eat pretty much anything.
- Fungus Humongous: A really big green mushroom-kat thing with tenracles.
- In-Series Nickname: Mac calls him "fungus fingers," while Dark Kat calls him "fungus face."
- Intangible Man: He's amorphous, capable of liquefying himself in order to ooze under closed doors and between tight spaces, allowing him to get into places Viper can't.
- It Can Think: Alone among Viper's monsters, he displays intelligence despite his monstrous nature and inarticulate growling. He is shown utilizing stealth to sneak up on enemies, and he was able to figure out that the "fisherman" assisting the SWAT Kats was actually Feral in disguise and unmask him.
- Mix-and-Match Critter: Half kat, half mushroom. With tentacles.
- Nigh-Invulnerability: He's very difficult (if not outright impossible) to kill, having survived being splattered everywhere by an explosion.
- Red Eyes, Take Warning/Glowing Eyes of Doom: When he's angry or attacking, his normally pink eyes glow red.
- The Speechless: He just growls and snarls.
- Unexplained Recovery: He's splattered all over the Turbokat when Megakat Biochemical Labs explodes, but is back just fine with Viper later on. Presumably he survived by pulling himself back together offscreen T-1000-style (likely, given his amorphous nature), or Viper just made another one (also likely).
- What Happened to the Mouse?: He doesn't reappear after "Katastrophe."
Also known as the married gangsters Mac Mange and Molly Mange. These feline felons died while escaping from Alkatraz prison, but Professor Hackle, who had no idea who they were, found them and transplanted their minds into powerful robot bodies. The result: two heavily armed mechanical mobsters with attitudes.
Tropes associated with The Metallikats:
- Arm Cannon: They're armed (ha) with forearm-mounted weapons which are called multi-weapons.
- Aww, Look! They Really Do Love Each Other: Yeah, they bicker almost constantly, but they've got each other's backs. Prime example; Molly gets electrocuted while the two are trying to rob the city mint annnd...Mac: MOLLY!! *runs to her side* Molly, are you okay? Say somethin'!Molly: Get the loot ya big sap... uhhh... *loses consciousness*Mac: Forget the loot, I'm gettin' you outta here!
- Back from the Dead/Unexplained Recovery: Twice! First Professor Hackle revives them, then they survive getting zapped by Feral in "Metal Urgency".
- Badass Longcoat/Nice Hat: When they wear clothes at all.
- Cats Are Snarkers/Deadpan Snarker: If they're not insulting each other, they're insulting the SWAT Kats. Or Mayor Manx. Or Commander Feral. Or...
- Cool Car/Weaponized Car: Their Metallikat Express.
- Damn, It Feels Good to Be a Gangster!: If nothing else, they really do love their work.
- Death by Secret Identity: In "Metal Urgency", they're the only villains who have found out the SWAT Kats' secret identities and try to kill them. They fail and are reduced to heads where they attempt it yet again but fail. Feral finally corners them with a special gun that will deactivate the Metallikats, who immediately try to barter the SWAT Kats' identities to him in order to be let go. Feral refuses the offer and deactivates them.
- Drives Like Crazy: Mac certainly does. Molly even declares him the worst driver in history. Mac rationalizes how he drives thusly: "I don't have to drive well in this little hot rod! Everyone else jumps outta the way!"
- Happily Married: More or less.
- I Lied: In "A Bright and Shiny Future," after they break their word to the Pastmaster, he's understandably upset. Mac outright says "I Lied" in response:Pastmaster: We had a deal!
Mac: I lied. Sue me.
- Killer Robot: Having the minds of two unrepentant gangsters probably has something to do with it.
- Like an Old Married Couple: Though they actually are married.
- Ninja Pirate Zombie Robot: Bonnie and Clyde as wisecracking Funny Animal Killer Robots and Back from the Dead.
- Outlaw Couple
- Shock Collar: In "Katastrophe", Dark Kat and Dr. Viper keep the Metallikats in their Legion of Doom by attaching "neuro scramblers" to their necks.
- Super-Powered Robot Meter Maids: There's no real reason that the bodies Professor Hackle gave them should be so heavily equipped for combat and crime. Professor Hackle just creates superweapons as a hobby without really considering what they'll be used for.
- Tiny Guy, Huge Girl: Mac is pretty stocky, while Molly towers over him.
- Ugly Guy, Hot Wife: From what we see of them in a flashback, Mac was stout and big-lipped before he became a robot. Molly, on the other hand...
- Weaponized Car: Their Metallikat Express.
An ancient sorcerer whose magical pocket watch functions as both a Time Travel device and a weapon that shoots energy beams. This medieval miscreant wants to return present day Megakat City to its Middle Ages incarnation of Megalith City, but he's also known for creating "time vortexes" to bring monsters from the past (like dinosaurs and mummies) into the present to do his bidding. And when he's not doing that, he's sending the SWAT Kats into the past or future in his latest effort to get rid of them.
Tropes associated with The Pastmaster:
- And Now You Must Marry Me: In "Bride of the Pastmaster," he is obsessed with forcing Queen Callista to marry him.
- Artifact of Doom: He has three of them: his watch, his Tome of Time spellbook ("The Pastmaster Always Rings Twice"), and the Jeweled Headdress of Katchu Piccu ("The Deadly Pyramid").
- Big "NO!": Is fond of unleashing these whenever he's defeated. In fact, he does it in all four of his appearances.
- Evil Luddite: He hates everything about modern technology, and his usual plans revolve around either trying to send Megakat City back to the Dark Ages or trying to return back home. Of course, this doesn't stop him from teaming up with the Metallikats to make a Bad Future where machines rule.
- Everything's Deader with Zombies: He rings up a buncha zombies in "The Pastmaster Always Rings Twice". Why? Just 'cuz!
- I Have You Now, My Pretty/Love Makes You Crazy: He kidnaps Queen Callista (in "Bride of the Pastmaster"), and then her lookalike descendant Callie Briggs (in "The Deadly Pyramid"), in separate attempts to marry them. The SWAT Kats rescue the withered wizard's intended victim both times. Thank God.
- Immortality Immorality: He views other kats as "foolish mortals" and doesn't think very highly of them, when he thinks of them at all, Callista (and later Callie) being a weird exception.
- In the Hood: Like Dark Kat, his face just kind of "floats" inside his hood when it's up, although one weird shot in "The Pastmaster Always Rings Twice" shows visible neck vertebrae. When he pulls the hood back, though, exposing his entire head, he has a visible neck.
- Nice Job Fixing It, Villain!: In "Bride of the Pastmaster". By tampering with the timestream, the Pastmaster accidentally brings the SWAT Kats to his time, thus fulfilling the prophecy. Oops.
- Ninja Pirate Zombie Robot: A skeleton kat-wizard.
- Pragmatic Villainy: More than some of the other villains. He never does evil things for evil's sake, and whether or not he kills (or tries to kill) "foolish mortals" is entirely dependent on what he's attempting to accomplish at the time. He lets the grave robbers go in "The Pastmaster Always Rings Twice" because he doesn't care yet whether anyone knows that he exists, but in "The Deadly Pyramid" he makes a concerted effort to kill Randall the photographer, and then Dr. Sinian and her assistant Henson, lest they escape and warn anyone of the coming mummy army. But once the SWAT Kats and Enforcers show up, the element of surprise is ruined, so he abandons all efforts to directly harm Sinian and co. and focuses his attention on attacking the city.
- Purple Is Powerful: A powerful wizard who wears purple robes. A lot of his magical energy (when it isn't reddish) is also on the purplish side.
- Really 700 Years Old: In "The Pastmaster Always Rings Twice", he mentions that he's been "imprisoned... for 800 years."
- Red Baron: His real name is never given.
- Sealed Evil in a Can: If only those grave robbers in "The Pastmaster Always Rings Twice" had picked another cemetery to desecrate...
- Skull for a Head: After a fashion. Not as much as the Red Lynx, though. He weirdly still has hair, his nose and cat ears though.
- Squishy Wizard: Depending on the Writer. Sometimes, he is just as physically weak as he appears; other times, he is surprisingly strong and tough.
- Time Travel: This is his main tactic.
- Uncertain Doom: We don't know if his fall into the molten lava at the end of "The Deadly Pyramid" is the end of him. He survived being essentially vaporized in "Bride of the Pastmaster," but who can say for certain?
- Unexplained Recovery: His being disintegrated along with his dragon in "Bride of the Pastmaster," he's back again just fine in "A Bright and Shiny Future."
A cyberpunk "technology pirate" who wears a "Surge Coat" that gives him the power to steal secured computer files, control vehicles, and turn into a Pure Energy form that can travel through power lines. The suit has one other interesting feature: when Hard Drive puts it on, his normal hairstyle automatically changes into a mohawk!
Tropes associated with Hard Drive:
- Badass Longcoat: The surge coat, which gives him his powers, doubles as this, at least visually.
- Blank White Eyes: In his case, they become yellow when he activates the Surge Coat.
- Clothes Make the Superman: Without the Surge Coat, he's just a normal kat.
- Energy Beings: He can become one when it suits him, provided he has the Surge Coat on, anyway.
- Made of Iron: He somehow survives two direct blasts from a bazooka, with and without the Surge Coat.
- An Offer You Can't Refuse: How Dark Kat coerces him into helping him.
- Power Dyes Your Hair: When he's normal, his hair is a shaggy brown mop the same color as his fur. But when he fires up the Surge Coat, his hair stands up into a mohawk and turns blonde.
- Psycho Electro: His Surge Coat gives him electrical powers, and he is often of questionable sanity.
- Red Baron: We never learn his real name.
- Technopath: When he wears the Surge Coat, he can control machines and other electrical devices using little bolts of electricity from his fingertip. For example, although he flies the stolen Turbokat manually by gripping the steering stick, he fires its weapons by sending a little electrical bolt into the control panel, somehow making the jet not only fire the missiles, but the specific missiles he wants.
Insane comedian Lenny Ringtail, whose mind snapped when he was turned down as a Talk Show host in favor of David Litterbin, lets himself be possessed by the vengeful ghost of a medieval court jester who suffered a similar rejection centuries ago. The result is Madkat, a wisecracking, shapeshifting harlequin who uses his magical powers to kidnap "the king, queen, knight and jester" (aka Manx, Briggs, Feral and Litterbin), then vanish into thin air before the SWAT Kats can stop him.
Tropes associated with Madkat:
- Asteroids Monster: At one point, when he's shot while in his giant bouncy ball form, he simply explodes into thousands of giggling miniature Madkat bouncy balls which then reform into the original Madkat.
- Attack Its Weak Point: It's revealed all the dingle-bells on Madkat's jester's cap must be destroyed to stop him.
- Big "NO!": Lenny Ringtail lets one fly when the asylum orderly watches The David Litterbin Show at the beginning ("Noooooo! Stop!"), and when T-Bone destroys the final bell on Madkat's cap, he, too, unleashes a pretty epic one upon being defeated.
- The Bad Guy Wins: Madkat temporarily manages this against Litterbin, Manx, Feral, Briggs, and even Razor before ultimately being blown away by T-Bone; Ringtail, meanwhile, is ultimately returned to the asylum, but not before seemingly regaining his fame and fortune as a result of all of the post-Madkat publicity.
- Combat Tentacles: When in his octopus form, he has several big yellow and orange tentacles.
- Deadpan Snarker: Okay, so he's not very deadpan, but he's definitely a snarker.
- Demonic Possession: He takes over the body of Lenny Ringtail. However, it's not a simple Villain Override like in most cases; he behaves as though he's actually both characters acting in unison, thus carrying shades of Fusion Dance as well.
- Killer Yo Yo: He conjures up a yo-yo consisting of two saw blades to cut open Feral's car.
- Lantern Jaw of Justice: Even before he possesses the body of Jay Leno Expy Lenny Ringtail, Madkat's got a serious jawline.
- Large Ham: Once Madkat possesses Ringtail. You can almost imagine the glee Roddy McDowall was having playing someone like Madkat. He's The Joker with the powers of Bat-mite.
- Monster Clown: What was your first clue?
- One-Shot Character: For a villain who appeared in only one episode, he has quite a fan following. Due to this, he's the only one shot villain to get a level in the video game.
- Powers via Possession: For both Madkat the possessor and Ringtail the possessed. Before being taken over, Ringtail was just a regular guy (albeit an insane one capable of breaking a baseball bat in half). Being possessed gave him superpowers. As for Madkat, before he takes over Ringtail, he's just a snarky ghost in a talking jack-in-the-box, and it's pretty obvious he needs a body in order to have his magic powers.
- Sealed Evil in a Can: His ghost haunts a creepy-looking jack-in-the-box in an antique shop.
- Sizeshifter: Madkat can be any size he wishes, from tiny enough to hide inside an envelope to growing about ten feet tall to intimidate Mayor Manx, and then even larger on the bridge later when he captures Feral.
- Slasher Smile: Probably has the scariest grin of all the villains.
- Reality Warper: Not unlike The Joker during the Emperor Joker storyline.
- Voluntary Shapeshifting: He can morph himself into a Madkat-themed anything, from a giant bouncy ball to a motorcycle to a giant octopus.
- Willing Channeler: Ringtail is persuaded to let Madkat take him over.
T-Bone: "Over my dead body!"
Red Lynx: "Mines already dead!"
During "Mega War II", enemy air ace The Red Lynx was the most dangerous pilot in the sky—until he met his match in the heroic Blue Manx, who finally shot him down. Decades later, The Red Lynx's plane is recovered and displayed in the Megakat Museum of History, an event which somehow revives his vengeful spirit. The so-called "ghost pilot" goes after the closest living relative of The Blue Manx—Mayor Manx, the flier's great-grandson, who happens to be in the middle of a re-election campaign.
Tropes associated with The Red Lynx:
- Ace Pilot: As noted above, he is an awesome pilot. He would have to be to fight a jet on even terms in an old biplane.
- Always Someone Better: He's actually a better pilot than T-Bone. Not only that, but T-Bone actually learned most of what he knows about dogfighting by studying him.
- Back from the Dead: Returns from the grave after his biplane is dredged up by some construction workers and taken to the museum.
- Demoted to Extra: Does appear in the Super Nintendo game, but you'd have to look hard and be intimately familiar with the show to pick him out.
- Goggles Do Nothing: Although he is seen with his flight goggles down over his eyes in the historical footage from the war, he never actually uses them in the present day (likely because he's dead and needs no eye protection) and they just sit up on his hat for decoration (or he doesn't care enough about his appearance to remove them).
- Only I Can Kill Him: See the Mayor Manx section for more details.
- A Nazi by Any Other Name/Putting on the Reich: Averted completely. Despite being repeatedly described as "the most evil pilot in history" and having what amounts to a German accent and dying in a war that was an Expy of World War II, he has more in common with Imperial German fighter pilots from World War I, both in name, dress and choice of aircraft.
- Red Baron: Not only is he an expy of the Trope Namer, but he's known only by his two nicknames—his real name is never revealed.
- Red Eyes, Take Warning: Has solid red eyes without any visible pupils.
- Roaring Rampage of Revenge: His motivation for coming Back from the Dead.
- Sins of Our Fathers: Debatable. Although he targets Mayor Manx because he's named Manx and Manx's great-grandfather is the one who shot him down, the episode is maddeningly unclear whether the Red Lynx even realizes this is a different member of the Manx family.
- Skull for a Head: Like the Pastmaster, though, he inexplicably still has kitty cat ears.
- Those Wacky Nazis: Averted. See above.
Mutilor: "And if this world perishes in the process, its just business."
Mutilor is an four-armed, vaguely lobster-like alien Space Pirate. Traag is his sycophantic aide-de-camp. Together, they and their mooks attempt to drain all the water from the SWAT Kats' world and sell it to a desert planet.
Tropes associated with Mutilor and Traag:
- Blank White Eyes: Mutilor has solid yellow eyes with no pupils. Averted with Traag, who has solid red eyes but does have pupils.
- Combat Pragmatist: Mutilor has no time for such silly things as Mook Chivalry. When the SWAT Kats manage to reach his control room, he orders pretty much his entire compliment of armed guards to just swarm the good guys and pile onto them. It works.
- Cool Ship: Mutilor stole his mothership from the Aquians, a kat-like race of Technical Pacifists.
- Evil Sounds Deep: With Michael Dorn playing Mutilor, what else would you expect?
- Large and in Charge: He's the biggest of all the evil aliens we see, and consequently their leader.
- Large Ham: Mutilor stands out in a series full of them.
- Multi-Armed and Dangerous: Mutilor, who possesses four really big, muscular arms.
- Outside-Genre Foe: Even in this series, it's hard to find a bad guy who is an alien, let alone an enemy not remotely cat related.
- Red Eyes, Take Warning: Traag has red eyes.
- Space Pirates: Mutilor is actually proud of this.
- Sycophantic Servant/Yes-Man: Traag.
- This Cannot Be!: More or less Mutilor's reaction when it turns out the SWAT Kats survived his Drowning Pit."How can this be?!"
- Worthy Opponent: How Mutilor regards the SWAT Kats."It was so refreshing to clash with true warriors. Its a shame I must destroy you."
Turmoil is a harshly beautiful villainness in a Nazi-like uniform. She attempts to conquer the skies of Megakat City with an Airborne Aircraft Carrier, an Amazon Brigade of female fighter pilots, and a disorienting "Vertigo Beam". When T-Bone withstands these obstacles, she's so impressed (and smitten) that she offers him a job as her flight commander—but first he must prove his loyalty by killing Razor.
Although she's officially a One-Shot Character, she was going to return in a second episode, aptly titled "Turmoil 2: The Revenge", before the series got canned. The script has been posted by a SWAT Kats fan site.
Tropes associated with Turmoil:
- Airborne Aircraft Carrier: She's the captain of a massive flying warship, complete with its own armada of fighter jets, the Omega Squadron.
- Amazon Brigade: All of her fighter pilots—and her crew in general—are women. She never met a man who could match them...until she saw T-Bone in action.
- Back for the Dead: She returns in the unfinished episode "Turmoil 2" only to fall off a cliff at the end.
- Benevolent Boss: She makes sure her Mook Lieutenant and other imprisoned Elite Mooks are up the rescue ladder during the prison break at the beginning of "Turmoil 2" before she herself climbs up. She does however kick off a prisoner named Olga who wasn't part of her original crew but who'd helped plan the escape, apparently just For the Evulz.
- Commie Nazis: She dresses like a Nazi but has a Russian accent.
- Dating Catwoman: Her relationship with T-Bone.
- Disney Villain Death: She gets swept off of a cliff to her presumed death by an avalanche.
- Does Not Like Men: A subtle example, in that her whole crew is female, and she's specifically mentioned that she never met a male pilot who could match them. Subverted, however, in that she's obviously not above admitting that T-Bone's an impressive pilot...or falling in love with him, for that matter.
- Femme Fatale: Especially noteworthy, as she was the only independent female villain of note to show up in the series.
- Hand Stomp: She tries to do this to Cybertron at the end of "Turmoil 2."
- I Lied: Said verbatim to Olga in "Turmoil 2" before kicking her off the rescue ladder, after she'd promised her she could come with her.
- If You're So Evil, Eat This Kitten: Puts T-Bone into this position to determine his loyalty.
- Just a Stupid Accent: She speaks in a vaguely Russian-like accent.
- Kill Sat: In the "Turmoil 2" script, she steals the Mega-Beam (a powerful laser intended to prevent earthquakes by sealing fault lines, previously featured in "Unlikely Alloys") and uses it to threaten Megakat City.
- Loves Only Gold: Both times, her plan has involved extorting huge amounts of gold from Megakat City, so it seems she really likes gold. She isn't so obsessed with it that she won't abandon it to safely escape her Collapsing Lair at the end of "Turmoil 2", though.
- Mind-Control Device: The "Turmoil 2" script has her using a "Crown of Obedience" to turn T-Bone into her mental slave.
- Pinned to the Wall: At one point in "Turmoil 2," she pulls a gun, but Razor fires a dart that pins the sleeve of her uniform against the wall, sticking her there.
- Putting on the Reich: Her uniform, complete with a Commissar Cap.
- Red Baron: You guessed it—no real name given. Unless, of course, Turmoil really is her name.
- Sky Pirate: She uses the Vertigo Beam to disable any aircraft over Megakat City, threatening the city unless she's paid a weekly protection fee.
- Taking You with Me: She tries this with a grenade at the end of "Turmoil 2," but T-Bone knocks it out of her hand. It blows up, creating an avalanche, so that she is the only one who gets (possibly) killed.
- Uncertain Doom: Although "Turmoil 2" ends with her falling off a cliff, considering how easily SWAT Kats villains survive incidents that should have killed them, who can say what happened to her?
- Ungrateful Bitch: Even though her cellmate Olga helped plan their escape from Alkatraz at the beginning of "Turmoil 2", when it comes time for them to leave, Card-Carrying Villain Turmoil kicks her off the escape jet's rescue ladder.
- Villainesses Want Heroes: Especially ones who can outfly their Elite Mooks!
- Would Hurt a Child: In "Turmoil 2", one of her Mega-Beam attacks endangers a school bus full of kids, but the SWAT Kats save them.
Shard is a brutal thug who winds up at Megakat Maximum Prison, whose greedy warden enriches himself by using the convicts to mine precious gems from the nearby mountains. When Shard has an accident with an experimental diamond mining machine, it somehow transforms him into a crystalline giant whose touch turns people and objects into crystal... and that's only the beginning of his new powers.
Tropes associated with Rex Shard:
- Achilles' Heel: Can be shattered by strong sonic vibrations, although to keep the episode from being too violent it actually just makes him shrink back to normal size.
- Blank White Eyes: After transforming, he has blank yellow eyes.
- Big "NO!": Unleashes a pretty epic one when he's shattered at the end.
- Frickin' Laser Beams: Focuses the sun's rays through his hand to create a solar laser beam.
- From Nobody to Nightmare: He used to be just another convict. Then he got super-powers. Then he grew to a hundred feet tall.
- The Magic Touch: Everything Shard touches turns into crystal, either brittle and fragile or hard as a diamond.
- Meaningful Name/Steven Ulysses Perhero: A guy named Shard in an episode titled "Chaos in Crystal" winds up with crystal-based powers and a crystalline appearance. Who'd have thunk?
- Miracle-Gro Monster: Shard is originally only transformed into a being made of diamond. When he is knocked into a room full of diamonds, he absorbs them into his body and becomes a giant. Later, he becomes even larger right before the final battle.
- Motive Decay: Big time. He starts out explicitly wanting revenge on Meece and Greenbox, even though his present condition is entirely his own fault, but after he turns them into crystal, he just sort of resorts to random acts of heinous crystallization, apparently for lack of anything better to do.
- Never My Fault: He blames Warden Meece and Dr. Greenbox for his condition, even though it's his fault for foolishly trying to open the compartment in the Gemkat 6000 containing the diamonds, resulting in the explosion.
- Nigh-Invulnerability: Being made of solid crystal means nothing can penetrate him. However, he can be cracked or shattered by loud enough sounds.
- No Ontological Inertia: Once Shard is de-powered, everything he crystallized reverts back to normal, starting from the last object he touched. The warden who got shattered is probably still in bad shape, though...
- Off with His Head!: Rolling, bodiless versions of his crystalline head show up as enemies in the Super Nintendo game, for some reason.
- One-Shot Character: Although he was intended to return in another episode, it never materialized.
- Rock Monster: Of a sort, being made out of green crystal.
- Walking Shirtless Scene: Before his accident, he's seen working in the mines in just pants and shoes, exposing his muscular upper body.
One of the SWAT Kats' first onscreen enemies (their second, in fact), Morbulus was a jet pilot who literally had eyes in the back of his head, giving him 360-degree vision and making him difficult to take by surprise. After being defeated by the SWAT Kats, he becomes a test subject for Dr. Viper, who mutates him into that episode's Fifty Foot Whatever, a ravenous purple bacteria monster.
Tropes associated with Morbulus:
- Alas, Poor Villain: The poor genius didn't quite deserve to go out as a monster.
- Asteroids Monster: Shooting the bacteria monster causes it to split apart into more bacteria monsters like an amoeba. Unlike many examples of this trope, the new monsters don't start out smaller than the original one. Also, it can only divide a limited number of times (see below).
- Beard of Evil: He is in fact the only character (besides a briefly-seen blacksmith in "Bride of the Pastmaster") who has a beard.
- Big "NO!": When he gets transformed. Dr. Viper replies with a Big "YES!".
- Blob Monster: The bacteria monster(s) he's turned into, although they have a definite humanoid shape with arms, legs, etc.
- Extra Eyes/Eyes Do Not Belong There: The aforementioned second pair of eyes in the back of his head. He even wears flight goggles with extra lenses. Interestingly, he's also one of the few characters in a show full of felines with slits for pupils (in all four eyes!).
- This allows the bacteria monster(s) he gets turned into to have eyes when they divide like amoebas. The original four-eyed monster divides into two monsters with two eyes, and one of those divides into two monsters with one eye. (A weird animation error, however, results in all three monsters having only one eye at one point.)
- Extreme Omnivore: The bacteria monster(s) eat pretty much anything.
- Faking the Dead: How he escapes the Enforcers.
- For the Evulz: Why he seems to be bombing oil refineries.
- High-Voltage Death: How he - or rather, the monster(s) he's turned into - gets killed. One monster is electrocuted by the third rail in a subway, another is fried from the inside out by a Megavolt Missile, and the third is killed when downed powerlines fall on it.
- Lantern Jaw of Justice: He's got a pretty big chin.
- Me's a Crowd/Self-Duplication: As a result of being an Asteroids Monster, the original four-eyed bacteria monster Morbulus gets turned into can divide, although the creature can apparently only do this three times to create four monsters, being limited by the number of eyes it has to divide up among the new monsters. The eyes themselves don't seem like they can divide (we never see a one-eyed bacteria monster divide).
- Mega-Microbe: What Dr. Viper turns him into after he agrees to let Morbulus "help" him. Kind of. It's unclear if the monster is a giant germ, or a monster made of germs. Either way, both the episodes title and the dialogue refer to it as a "giant bacteria."
- Miracle-Gro Monster: The original bacteria monster is only slightly larger than a regular kat. The more the creatures eat, however, the larger they get. The final one is the size of a building.
- Nigh-Invulnerability: Of the "Made of Liquid" variety. Ordinary weapons won't do a thing against the bacteria monsters. They'll either pass through their bodies, or, worse, cause them to divide. Only heat and/or electricity seems to kill them.
- Not the Fall That Kills You: Twice he gets dropped from great heights. The first time, he's grabbed out of the sky by the SWAT Kats, stopping his fall so suddenly he should've broken his neck and back. Afterward, they let him go from a lower height and he drops into the ocean.
- Rasputinian Death: Covered in Gunge, mutated into a Mega-Microbe Blob Monster, and then Killed Off for Real (three times!). They REALLY did not want this guy coming back.
- Slasher Smile: As the bacteria monster(s). They have permanent, open-mouthed evil grins.
- Stock Underwear: He has to ditch his clothes at one point, and winds up in purple boxer shorts and a wifebeater.
- Throwing the Distraction: He escapes from the Enforcers by taking his clothes off underwater, then reassembling them to make it look like he's still in them. Overlaps with Giving Them the Strip somewhat.
A crazy helicopter pilot who the SWAT Kats fight. Despite being described as "their most elusive adversary," they pursue him for all of one minute before defeating him. He may or may not be a hyena, something which is hotly debated in the fandom.
Tropes associated with Chopshop:
- Bit Part Bad Guy: He's in "SWAT Kats Unplugged" only very briefly.
- Blank White Eyes: He has solid green eyes without pupils.
- The Hyena: He has a very annoying laugh, which leads T-Bone to call him a "laughin' hyena."
- Know When to Fold 'Em: After initially being defeated, he gets out his helicopter with laser gun blazing... only to have Felina shoot the weapon from his hand, whereupon he instantly surrenders.
- You Gotta Have Blue Hair: He has a big pink mane. It's probably dyed.
An enormous fire demon released from a volcano.
Tropes associated with Volcanus:
- Blank White Eyes: The usual evil yellow eyes without pupils, something of a running theme among SWAT Kats villains.
- Convection Schmonvection: Zig-zagged. Razor needs a heat suit to get close enough to him to plant the bomb in his weak spot, but when he grabs Feral's helicopter, the aircraft doesn't melt, and Feral is able to climb out through the smashed windshield and grab a lifeline the SWAT Kats drop him, with no ill effects from the heat that must be pouring off of the hand holding his copter.
- Fireballs: His main weapon, which he forms in his hands and throws.
- Implacable Man: He just relentlessly marches forwards without hardly ever changing expression, and shrugs off pretty everything the SWAT Kats and the Enforcers throw at him. The most he ever really does is narrow his eyes in slight annoyance.
- In-Series Nickname: "Lava lips."
- Kill It with Water: Averted. When he wades into the ocean chasing Mayor Manx and his party in their speedboat, he sinks under, and Manx assures everyone that "the water has put out the fire demon." Unfortunately, once they pull up to the pier, Volcanus erupts out of the water, having been too hot for the mere ocean to put out, and just walked along the ocean floor to reach Megakat City.
- Mighty Glacier: He may not be fast, but he's very big and immensely powerful, and often just needs to casually walk into (and through!) buildings to destroy them.
- Nigh-Invulnerability: He's huge and made of what appears to be solid rock with lava underneath. Conventional weapons don't do diddly to him. However, despite being a demon, he can still be killed if hit in just the right spot, and Razor sticks a bomb in said weak spot, causing Volcanus to blow up real good.
- Playing with Fire: Being a fire demon, he has a variety of fire-based powers, particularly the ability to breath fire and form fireballs in his hands to throw them.
- Rock Monster: Part of being an ancient, evil fire demon.
- Sealed Evil in a Can: He was imprisoned inside the volcano on Anataka Island, kept there by the power of the Talisman Stone, until an unwitting construction worker drove his bulldozer into the Stone, shattering it, unleashing Volcanus.
- The Speechless: He never speaks, just growls and roars. Either he is incapable of speech or just has nothing to say to the puny little mortals he's trampling underfoot.
- Supernatural Body Heat: He gives off body heat so extreme that he can melt things just by touching them. He walks through a bridge in this fashion as it melts like it's made of wax.
- Ungrateful Bastard: Probably unintentional, but the first thing he does upon being released is destroy the bulldozer that hit the Talisman Stone and freed him.
An astronomer employed at MASA (Megakat Aeronautics and Space Administration) who discovers, and is taken over by, the Ci-Kat-A. He slowly turns into one as he attempts to help them conquer the world.
He appears in only one finished episode, "The Ci-Kat-A", but he would have returned in one of the three unfinished episodes, "The Doctors of Doom", in which he would have done a Villain Team-Up with Dr. Viper. A detailed plot outline is available here.
Tropes associated with the Ci-Kat-A:
- Alas, Poor Villain: Although it's a little unfair to call him a villain, considering he never had much choice once he got bitten, he's still an antagonist and comes to a really bad end in the unfinished episode "The Doctors of Doom." Betrayed by Dr. Viper, he gets mutated (even further!) and turned into a giant scarab, then killed off.
- All Webbed Up: Turns out - as per "The Doctors of Doom" - that he and the other converted kats can puke yellow slime to cocoon victims just like the "natural" Ci-Kat-A can.
- Assimilation Plot: In "The Ci-Kat-A," he never bites anyone personally, although he does try and give Callie a nibble. In the unfinished ep. "The Doctors of Doom," however, he does get to bite and convert a group of escaped convicts.
- Back for the Dead: Returns in "The Doctors of Doom," one of the unfinished episodes, only to get mutated into a giant scarab and then killed off.
- Big Creepy-Crawlies: Like all the kats the Ci-Kat-A convert, he's slowly turning into one of them. And in "The Doctors of Doom" he becomes an enormous beetle, courtesy of Dr. Viper.
- Brainwashed and Crazy: His state the moment he's bitten by the queen. Even after she dies, he continues insisting (as per the unfinished episode "The Doctors of Doom") that the Ci-Kat-A are the superior race and must conquer Megakat City.
- Destination Defenestration: He's blasted out the window of the penthouse at the end of "The Ci-Kat-A," to his supposed Disney Villain Death.
- Disney Villain Death: Averted. It's suggested at the end of "The Ci-Kat-A" (his wings notwithstanding), then the unfinished episode "The Doctors of Doom" reveals he survived. And at the end of the episode, he, in his mutated form, falls down the flooded nuclear power plant cooling tower to simultaneously drown and be crushing by falling chunks of concrete.
- Good Scars, Evil Scars: In "The Doctors of Doom," it would've been revealed that he has scars radiating out from the center of his face from where the Octopus Missile's claws dug into him.
- Hive Mind: The queen may be dead, but the hive mind remains. Street however seems mostly free of any control (considering there's no one to control him) and operates independently. However, anyone he bites instantly obeys him.
- Insufferable Genius: Sorta. We see very little of him before he gets bitten and turned, but the way he talks about "the fools here" at MASA suggests he has some traits of this.
- Lab Coat Of Science And Medicine: Although it becomes more and more tattered and shredded as the episode goes on and his transformation keeps progressing.
- Mad Scientist: His scientific background doesn't enter into things much during the events of "The Ci-Kat-A," but by the time he's teaming up with Dr. Viper in the unfinished episode "The Doctors of Doom," he's become a full-fledged mad scientist, following his ally's example by paying Megakat Biochemical Labs and its vast store of katalysts a visit.
- Mix-and-Match Critter: Half kat-alien bug, half kat. Then half kat-alien bug, half kat and half giant beetle. Yikes.
- Sinister Shades: Wears them during the early stages of his transformation to hide his (literal) bug eyes. He doesn't get to do a cool Glasses Pull reveal like the guard, though.
- Super Drowning Skills: In his mutant beetle form, he can't swim, and drowns inside the flooded cooling tower. The debris landing on him and pushing him under the water didn't help.
- Villain Teamup: With Dr. Viper. It doesn't last long.
Tropes associated with the Ci-Kat-A:
- All Webbed Up: They can excrete a thick yellow slime from their mouths to cocoon enemies.
- Assimilation Plot: This seems to be their queen's plan besides laying eggs and creating tons of drones. The first thing she does is bite MASA's Dr. Street and a security guard. Her children also bite and convert several kats.
- Bee People: Their social structure is just the queen and her many, many drones. Unlike some examples, though, the queen is indistinguishable from her natural children apart from her size (even before growing to Kaiju size, she was taller than a normal Ci-Kat-A).
- Big Creepy-Crawlies: They're kat-sized purple bugs. The queen becomes even bigger eventually.
- Bizarre Alien Biology: They reproduce both by a female who lays eggs, producing apparently male drones, and by biting and converting beings native to whatever world they live on. They also eat radioactive materials, vomit a sticky yellow slime to cocoon victims... the list goes on.
- Body Horror: Anyone bitten by a Ci-Kat-A begins slowly turning into one.
- Glasses Pull: When a MASA guard who'd been bitten by the queen confronts Ann and Jonny ("I warned you!"), he whips off his Sinister Shades to expose his insectoid eyes.
- Helicopter Blender: One is knocked into the rotors of an Enforcer chopper. It cuts away just before we see him hit.
- Hive Mind: Suggested by the fact that whoever gets turned into a Ci-Kat-A by bite immediately starts obeying the queen without question.
- Insect Queen: The queen, the largest and most intelligent of all the Ci-Kat-A, and (apparently) the only one capable of laying eggs. Weirdly, the SWAT Kats often refer to her with male pronouns ("Fly in close and tie up his wings!").
- Insectoid Aliens: This describes them in a nutshell.
- Kill It with Fire: The Enforcers torch the queen's second nest in the Megkat Tower.
- Monster Is a Mommy: The original alien who comes down aboard Kat Sat 1 is female, and consequently, all the Ci-Kat-A except the ones created through biting are her offspring.
- Offhand Backhand: Done to a nuclear power plant technician by the queen. He yells at her that "This is a secured area!" and she simply knocks him aside.
- Make Me Wanna Shout: Ci-Kat-A emit a piercing shriek which is painful to the ears and capable of shattering glass.
- Miracle-Gro Monster; The queen grows to Kaiju size after gobbling up a few nuclear fuel rods.
- Mix-and-Match Critter: Half alien bug, half kat.
- Outside-Genre Foe: Like Mutilor, they're evil aliens rather than terrestrial enemies.
- Phlebotinum Muncher: They eat radioactive materials, gobbling the stuff up like it was candy.
- Purple Is Powerful: The queen and her offspring all have purple fur.
- Red Eyes, Take Warning: The "natural" Ci-Kat-A (i.e., the queen and her brood) have red compound eyes. Averted with the kat victims who are bitten and turn into Ci-Kat-A; their compound eyes are green.
- Rubber-Forehead Aliens: They're kat versions of this. They inexplicably have pointed kitty ears, furry cheek tufts, feline tails, etc. in the same way aliens in Star Trek have inexplicably human traits. They could easily be kat actors in costumes.
- Sinister Shades: The converted kats wear them during the early stages of their transformations to hide their green compound eyes.
- Squashed Flat: The queen is killed when the burning penthouse of the Megakat Tower falls on top of her, crushing her to death.
- Taking You with Me: After the SWAT Kats tie up her wings so she can't fly, the queen grabs Razor out of the Turbokat as she falls, intent on dragging him down with her.
- The Virus: How their bite seems to work; anyone bitten by a Ci-Kat-A turns into one.
- The Voiceless: Except for those among them who used to be kats, they're incapable of speech (at least the sort of speech kats understand). And except for Street, even the former kats seem to gradually lose their ability to speak (that or they just have nothing to say).
- What Happened to the Mouse?: We never do learn the fate of the Ci-Kat-A who got sent into space aboard the MASA rocket, and five converted MASA guards in the early stages of their transformation are also unaccounted for at the end of the episode.
An unused villainess that would've debuted in "Succubus!" (a.k.a. "The Curse of Kataluna"), Katrina is a wealthy heiress and a major investor in Megakat City. She owns Moorkroft Manor and the Moorkroft Philharmonic Hall. Described in Glenn Leopold's script as "mysteriously beautiful," she is in reality an evil succubus who drains the life from her victims. She tries to do so to Commander Feral. While "Succubus!" was never finished due to SWAT Kats' abrupt cancellation, you can read the script here.
Tropes associated with Katrina:
- Benevolent Boss: She surprisingly treats her servants quite well.
- Big "NO!": She utters one when she is defeated just before poofing into dust.
- Bitch in Sheep's Clothing: She may seem nice, but she is anything but.
- Does This Remind You of Anything?: She is describing as writhing in ecstasy and issuing forth "gasping moans" as she drains her victims' life energy.
- Eye Beams: She is described as firing "lasers" from her eyes.
- Getting Crap Past the Radar: Sure, a life-sucking creature disguised as a woman doesn't sound bad to any ears, but it was pretty ballsy directly calling Katrina a succubus (y'know, the same species as Morrigan Aensland) in a kid's show.
- This would appear to be the reason behind changing the episode's name from "Succubus!" to "The Curse of Kataluna" (although the name Kataluna doesn't appear anywhere in Leopold's script).
- Has a Type: All three of her on-screen victims (Feral, a dockworker and a construction foreman) are big, muscular men.
- Horny Devils: A feline-flavored one.
- Life Drinker: She drains her victims (all male) until they are nothing but lifeless husks. If this is done after she has aged into an old woman, she'll be instantly restored to youth and beauty.
- No Body Left Behind: But only because she ages into dust when she is prevented from completely draining Feral.
- One-Winged Angel: She transforms into a hideous demon at the end.
- Race Against Time: She has to finish draining Feral before the next lunar eclipse or she dies.
- Rapid Aging: She is prone to this if she goes for too long between feedings.
- Really 700 Years Old: She is not as young and pretty as she seems to be...
- Serial Killer: As of the beginning, she has killed at least six people in Megakat City.
- Villainesses Want Heroes: She pursues Feral romantically, but only to drain his life energy.
- Voluntary Shapeshifting: She can transform into a huge demonic beast if she feels like it.
- You Have Failed Me: Said verbatim to her pet ferret which turns into a three-headed monster after he fails to kill Callie, Felina and Dr. Sinian. However, she doesn't harm him.
Unused henchmen who would've appeared in "Succubus!" (a.k.a. "The Curse of Kataluna"). Otto is Katrina Moorkroft's chauffeur, and Laszlo is her butler. There is also a third servant who isn't named. All three turn into gargoyles.
Tropes associated with Otto and Laszlo:
- Battle Butler: Both of them, although only Laszlo is an actual butler.
- Co-Dragons: To Katrina.
- Eye Beams: Like Katrina, they shoot "lasers" from their eyes in their monster forms.
- Life Drinker: They, and the third servant, get extended life from the male victims of their employer. Which would appear to make them incubi, as all three are males.
- No Body Left Behind: They disintegrate into dust when Katrina dies.
- No Celebrities Were Harmed: Otto is described as resembling Erich von Stroheim (likely as Max in Sunset Boulevard).
- Not So Harmless: Initially, they and the gargoyles seem to be separate characters. The gargoyles abduct Katrina's victims for her, while Otto and Laszlo are just creepy servants. But when Felina attempts to arrest them, they reveal they and the gargoyles are one and the same by turning into them. Oops.
- Our Gargoyles Rock: When in their monster forms.
- Really 700 Years Old: Unlike Katrina, it is unknown how old they are. One assumes that they've been with her a sufficient amount of time that they, too, are older than they appear, although unlike her they're not subject to any Rapid Aging - that we see.
- Terrible Trio: Along with the third unnamed servant.
- Undying Loyalty: To Katrina.
- Voluntary Shapeshifting: Again, like their employer, they are capable of transforming, although into creatures described as gargoyles rather than demons.
