Characters / Wild Kratts

The Wild Kratts Crew

Chris Kratt

Voiced by: Himself

• Alliterative Name: It sounds that way, at least.
• Ambiguously Brown: Justified, since he's somewhat dark skinned (for a Caucasian) in real life.
• As Himself: Chris Kratt stars as himself.
• Badass Adorable: A gentle guy who cares for both his loved ones and animals, but despite his and Martin's claims that they are not much of fighters in "Choose Your Swordfish", he also has Creature Power Suits that he can use to kick some real ass, protect those he cares for, and won't hesitate to attack if he needs to, especially if to protect his older brother, Martin.
• Badass Bookworm: He definitely has the bookworm part down, as the more analytical of the brothers, and while he's not a major fighter, he's still badass on his own when he has a Creature Power Suit on, especially if he's protecting Martin.
• Blue Oni: Or is he a green oni?
• Big Brother Instinct: Very much in existence, and Chris has got quite the Little Brother Instinct of his own.
• Brainy Brunette: He has brown hair and is the more logical of the brothers (not that Martin is a Dumb Blonde), and has also displayed a little Gadgeteer Genius with Technobabble.
• Chronic Hero Syndrome: He always has to help an animal in need, no matter what.
• Color-Coded for Your Convenience: Green, since 1994.
• Curtains Match the Window: Amusingly (and adorably) justified- in real life, his hair and eyes are brown.
• Damsel out of Distress: A Rare Male Example. He get captured by villains and gets into other kinds of danger often but he is perfectly capable of saving himself or at least making significant progress until the team finds him.
  • It also applies if he was in danger alongside someone else as well, like in "Amazin' Amazon Adventure", where after he and Martin got kidnapped by the villains (and thus spending a good chunk of the second half as captives to the villains), and both brothers saw they Koki is on her way to free them (albeit disguised as a mannequin), Chris pretended to have an itchy back, knowing that Donita will have her mannequin scratch his back for her, allowing Koki to remove their cuffs and kickstart the climax.
• Earthy Barefoot Character: While he and Martin are usually just "Earthy Character", in their Opossum Creature Power Suits, a bit of their feet are noticeably exposed to make way for the thumb power in both their arms and legs.
  • "Bass Class" also has him and Martin barefoot for the whole episode, and it becomes noticeable when everyone else were wearing shoes at the time, including Zach, the enemy who tried to cheat in the episode.
• Freudian Trio: With Aviva and Martin.
• Friend to All Children: The various kids that the Kratt Team interact with clearly like him a lot and he's always shown to be great with them.
• Going Commando: A Zig-Zagging Trope. In the episode “Musk Ox Mania”, he is shown wearing light green boxers covered in dark green Wild Kratts Crew logos after a rhinoceros’ horn snagged his cargo shorts. At the same time, the viewer get multiple scenes where the inside of Chris’ cargo shorts can be seen with no underwear visible.
• The Hero / The Lancer: Switches between both with Martin.
• Heterosexual Life-Partners: With Martin.
• I Want My Mommy!: In "Road Runner", after crashing onto a cactus while trying to find the mystery lizard, he only has one thing to say.
  Chris: Mommy...
• Ink-Suit Actor: He resembles his voice actor.
• Keet: He is calmer than Martin, but he is energetic on his own, especially when it comes to discovering creatures.
• Large Ham: Subverted. More like Small Ham.
• Magic Pants: Or magic underpants in this case as Chris is shown at least once wearing boxers, and yet at the same time, the viewer gets multiple shots up his cargo shorts with no light or dark green visible.
• Nice Guy: He's very friendly, and even is willing to Save the Villain at times, even if they won't always return the favor.
• Primal Stance: Poses like this at the end of the opening theme song.
• Pungeon Master: Subverted, but he gets his in.
• Real Men Cook: Before it was established that Jimmy is both the Team Chef and a Supreme Chef, as well as the episode “Uh-Oh Ostrich” revealing that both Aviva and Koki can make at least one dish of chocolate pudding cups with blueberries to rival Jimmy’s cooking, the episode “Honey Seekers” shows that both Martin and Chris are able to cook breakfast while camping in the African Savannah using only a campfire, a few cooking utensils, and various preservatives.
• Real Men Wear Pink: A Zig-Zagging Trope as it depends upon the episode. In the episode “Zig-Zagged”, both he and Martin repeatedly voice their concerns and opposition about wearing hippo belly pink on their crew jackets, with the only other concern they have is all of the animal patterns the girls are using. In the episode “The Colors of China”, when the bros are having their colors restored, after having lost their color saving the animals from Donita’s clutches, a glitch in Aviva’s color restoration wand causes the bros to end up with suits that are different from their usual colors, with Chris getting pink on the second attempt and while he doesn’t say anything his facial expression screams “what on earth am I wearing” with his mouth open in shock staring down at his creature suit. In the episode “Mystery of the Pink Flamingo”, both of the bros wrestle with one another over who gets to use the single flamingo power disc, which is especially notable as this is one of the few times that both of them have worn a differently colored creature suit from their usual favorite colors of blue and green.
• Share Phrase: He shares "To the creature rescue!" and "Free and in the wild!" with Martin.
• Shorter Means Smarter: He's shorter than Martin, and while Martin is not an idiot at all, Chris is ultimately the more analytical of the brothers.
• Sesquipedalian Loquaciousness: Chris once descended into severe technobabble ("Mystery of the Squirmy Wormy", as they were setting up the miniturizer) and has spouted words like "monotremes" ("Platypus Café").
• Sibling Team: The only person who can match Chris stride for stride is Martin, and they are very productive together.
• Tempting Fate: This is pretty much Chris's shtick.
  Chris: "No worries Bro! I'm getting this roo kickboxing thing down better than I thought-" WHAMTHUD "...Scratch that."

Martin Kratt

Voiced by: Himself

• A Simple Plan: Has a fondness for plans that sound like they should be smooth-sailing but rarely end up being that way.
• As Himself: Martin Kratt voices himself.
• Attention Deficit... Ooh, Shiny!: And flashy, and yummy, AKA Martin-the-bass has a little problem with lure reactions. Also averted with a LOT of the episodes—okay, fine, every episode—because the Kratts always get distracted, and never stay on their ONE task assigned, although they come to their senses eventually.
• Badass Adorable: Energetic for sure, and definitely cares for both animals and his loved ones, but even though he and Chris claim they are not much of fighters in "Choose Your Swordfish", when he has a Creature Power Suit, he is not someone to underestimate whatsoever, since he can attack if he has to in order to protect those he cares for, especially if he finds out Chris is hurt.
• Badass Bookworm: Not as analytical as Chris, but he still proves to be intelligent when it comes to animals in general, and while he isn't much of a big fighter, he does prove to be competent when he gets into action in his Creature Power Suits.
• Big Brother Instinct: Any time Chris gets into danger/trouble, Martin is immediately worried and wants to run to the rescue immediately. Case in point: when a mission involving bees goes off the rails and Chris ends up missing overnight, Martin spends the entire time panicking and blaming himself.
• Big Eater: Almost as easy to hunger as Jimmy is, down to often packing food for his adventures and sometimes even eating them during his adventures. In fact, he once ate a WHOLE CAKE like it was nothing.
• Blue Is Calm: Inverted. He is associated with blue, but while he is capable of getting serious if he needs to, he's overall the more energetic brother of the Kratt brothers.
• Blue Is Heroic: His theme color is blue, and he's one of the good guys.
• Childish Older Sibling: Downplayed. He is more childlike than his younger brother, Chris, but he is capable of getting serious when needed.
• Chronic Hero Syndrome: He always has to help an animal in need, no matter what.
• Cloud Cuckoolander: He has a tendency to be strange sometimes.
• Color-Coded for Your Convenience: Blue, since the old days.
• Cool Big Bro: He may be somewhat of a Childish Older Sibling compared to Chris, but ultimately, he does care for him and is always willing to protect him when he needs him, something Chris appreciates.
• Crazy-Prepared: Or he likes to pretend so.
• Distressed Dude: He gets captured as often as his brother does, but the crowning example is in "Flight of the Draco", where he was forced to model for Donita in a tacky outfit, and that case is the first time a member of the crew was captured by a villain.
• Drives Like Crazy:
  • Martin does a bit of this off-screen in "Let the Rhinos Roll!", in which he apparently drives their jeep flying over a ravine. Chris good-naturedly chews him out over it while he fixes the poor thing.
  • There's some on-screen bad driving by Martin in the beginning of "Aardvark Town." It could be argued that Chris can't drive either, judging by his handling (or lack thereof) of the sub at the beginning of "Whale of a Squid", as well as the Butterflier XT.
• Dumb Blonde: Averted, as Martin is actually misleadingly intelligent, given his seemingly immature behavior.
• Earthy Barefoot Character: While he and Chris are usually just "Earthy Character", in their Opossum Creature Power Suits, a bit of their feet are noticeably exposed to make way for the thumb power in both their arms and legs.
  • "Bass Class" also has him and Chris barefoot for the whole episode outside of his Creature Power Suit, and it becomes noticeable when everyone else were wearing shoes at the time, including Zach, the enemy who tried to cheat in the episode.
• Freudian Trio: With Aviva and Chris.
• Friend to All Children: The various kids that the Kratt Team interact with clearly like him a lot and he's always shown to be great with them.
• Going Commando: A Zig-Zagging Trope. In the episodes “Puffin Rescue” and “Choose Your Swordfish”, he is shown wearing light blue boxers covered with dark blue Wild Kratts Crew logos in the former and the classic white with red polka dot boxers in the latter. At the same time, the viewer gets to see the inside of Martin’s cargo shorts multiple times with no underwear visible. Additionally, when he is stripped of his clothes by a tree branch alongside his brother in the episode “To Touch a Hummingbird”, the inside of his cargo shorts are visible with no underwear visible.
• Hair of Gold, Heart of Gold: Blond hair, and caring to almost everyone he meets, both animal and person.
• The Hero / The Lancer: Switches between them with Chris.
• Heterosexual Life-Partners: With Chris.
• Heavy Sleeper: Subverted. Heavy in context to the rest of the cast; minor compared to Jimmy.
• Ink-Suit Actor: He resembles his voice actor.
• Keet: While it isn't sugar-high, he's certainly more energetic than his brother, Chris, and overall is the most energetic member of the Tortuga crew.
• Large Ham: Ever since Kratts' Creatures in 1994.
• Magic Pants: Or magic underpants in this case as Martin is shown at least twice wearing boxers, and yet at the same time, the viewer gets multiple shots up his cargo shorts with no white, blue or red visible.
• Manchild: Subverted with Martin- he can get serious when he needs to be, but other than that, he acts more like the target audience than the Periphery Demographic.
• Nice Guy: Always willing to help a creature in need.
• The Nicknamer: At least since Zoboomafoo.
• Pungeon Master: Due to being both Cloud Cuckoolander and a Large Ham.
• Real Men Cook: Before it was established that Jimmy is both the Team Chef and a Supreme Chef, as well as the episode “Uh-Oh Ostrich” revealing that both Aviva and Koki can make at least one dish of chocolate pudding cups with blueberries to rival Jimmy’s cooking, the episode “Honey Seekers” shows that both Chris and Martin are able to cook breakfast while camping in the African Savannah using only a campfire, a few cooking utensils, and various preservatives.
• Real Men Wear Pink: A Zig-Zagging Trope as it depends upon the episode. In the episode “Zig-Zagged”, both he and Chris repeatedly voice their concerns and opposition about wearing hippo belly pink on their crew jackets, with the only other concern they have is all of the animal patterns the girls are using. In the episode “Aye Aye”, Martin wears a hot pink bandanna as part of his pirate outfit with neither him nor the rest of the crew commenting on it. In the episode “Mystery of the Pink Flamingo”, both of the bros wrestle with one another over who gets to use the single flamingo power disc, which is especially notable as this is one of the few times that both of them have worn a differently colored creature suit from their usual favorite colors of blue and green.
• Red Oni: To Chris' Blue Oni.
• Share Phrase: He shares his catchphrases with Chris. "To the creature rescue!" and "Living free and in the wild!" and less frequently, "Saving the planet with creature powers!" spring to mind.
• Sibling Team: The only person who can match Chris stride for stride is Martin, and they are very productive together.
• Terms of Endangerment: Donita, who actually kidnapped Martin in her debut episode (albeit unintentionally), refers to him as “Martino”.
• Trademark Favorite Food: Chocolate.
  Chris: “You thinking what I'm thinking?”
  Martin: “That everything taste better dipped in chocolate?”

Aviva Corcovado

Voiced by: Athena Karkanis

• Action Girl: There are a few times where she is willing to get into action, Creature Power Suit or not, against the villains, with one example being that in "Lemur Legs", while Jimmy and Koki focus on freeing the Kratt brothers and the captured sifaka lemurs respectively, Aviva willingly decides to battle Gourmand to keep him distracted from the other 2.
  Aviva: Get the bros out of here, I'll handle Gourmand!
• Badass Adorable: A sweet and caring inventor who can be somewhat sassy and loves cute animals...and not only is she able to kick ass in her Creature Power Suits, she has been shown to be a good fencer as shown in "Choose Your Swordfish", where she battles Zach in order to save the brothers, WITHOUT NEEDING TO ACTIVATE A CREATURE POWER SUIT.
• Badass Bookworm: She is The Smart Girl of the group who also proves to be willing to confront the villains, even without a Creature Power Suit.
• Badass Normal: She can activate a Creature Power Suit, no problem, but she is shown to be capable of battling without one, such as directly confronting Gourmand for trapping the brothers in "Lemur Legs" or doing a fencing match against Zach in "Choose Your Swordfish" to get him to let the brothers go.
• Berserk Button: She has a couple.
  • Telling her that she throws like a gi-
    Aviva: Don't you say it!
  • Messing up her inventions will also anger her.
• Brainy Brunette: She has brown hair, and she knows a lot about science and engineering, serving as The Smart Girl for the team.
• Butt-Monkey: She gets a good deal of Amusing Injuries in some episodes.
• Character Catchphrase: “Awww, que lindo!” = “How cute” in Spanish
• Color-Coded for Your Convenience: When she uses a Creature Power Suit, it's purple.
• Competition Freak: Moreso than Zach. Not only does she have a rivalry with him, but she's also challenged the brothers, and nature itself ("Cheetah Racer" against the cheetah, "Platypus Café" when she thought she could figure out Plato's "sixth sense" on her own…).
• Cuteness Proximity: Shown in various episodes where the team encounters baby animals and/or animals that are traditionally adorable.
• Freudian Trio: One with Chris and Martin, and another with Koki and Jimmy.
• Gadgeteer Genius: Responsible for the creation of the Creature Power Suits and other potentially world-changing inventions, like the Miniaturizer.
• Giver of Lame Names: Aviva names a flying fish "Fishy" and calls her stuffed toy panda "Stuffo". Subverted with the lion cub she dubbed "El Cutissimo", which is an unusual but serviceable name.
• Graceful Ladies Like Purple: Downplayed. She is associated with purple, though Aviva is more of a Tomboy with a Girly Streak.
• Gratuitous Spanish: Subverted and later averted.
• Hartman Hips: Not to an unrealistic extent, as while her waist is not that small, she does have some curves in her hips. They're mostly prominent when she's in her wetsuit.
• Know-Nothing Know-It-All: Most notably in "Platypus Café", and mostly due to her Competition Freak tendencies.
• Lady Looks Like a Dude: While averted for her normal attire, despite dressing rather tomboyishly, in the second Halloween Episode, she plays it straight with her costume as Zach (a guy), as she is able to pass as him (and even was able to fool him with that when she took advantage of that before she went back to her normal hairstyle).
• Meaningful Name: Corcovado is a city in South America. Her first name Aviva means ‘Springtime’ in Hebrew, fitting for a main character in a show about nature.
• Phenotype Stereotype: She's Latina, and she has brown skin.
• Pink Means Feminine: Downplayed on both accounts, she is sometimes seen with pink, but she is more of a Tomboy with a Girly Streak.
• Puppy-Dog Eyes: Aviva's common reaction whenever delighted by any adorable baby animal she sees. A prime example is when she saw Thornsley for the first time.
• Purple Is Powerful: An Empowered Badass Normal (can use the Creature Power Suits and is willing to confront the villains without one, sometimes with her inventions) who sports purple.
• The Smart Girl: Serves as this to the team, as she makes all the gadgets.
• Technobabble: Delves into this at times.
• Tomboy with a Girly Streak: She is an inventor with a competitive streak, and dresses tomboyishly most of the time, but she also loves cute animals (especially ponies) and dresses as a fairy in the first Halloween Episode.
• Tsundere: A prominent Type B. She's usually a nice person, but you don't want to make her angry.
• Villainous Crossdresser: An Inverted Trope, as well as a Gender-Inverted Trope, with Aviva crossdressing as Zach Varmitech when she, Jimmy, and Koki decide to dress as the villains for their costumes in the Halloween special.
• Vocal Evolution: She started off with a fairly deep voice, but at some point she gets a higher voice that also comes with a more cheerful side.
• Wrench Wench: She's the original inventor of the Creature Power Suits along with most of the Wild Kratts' creature-inspired gadgets.

Jimmy Z

Voiced by: Jonathan Malen

• Badass Adorable: It's downplayed compared to the other members of his crew, but he is still a Lovable Coward who can fight off the villains to protect the rest of his crew members, and without even needing to activate a Creature Power Suit as of April 2024, no less.
• Big Eater: He loves eating.
• Brilliant, but Lazy: He has been shown sleeping a lot, and is relatively mellow in comparison to the rest of the gang, but he's ultimately a competent pilot who can get the job done, no problem.
• Butt-Monkey: Especially in "Elephant in the Room". He's also punched himself in the face (twice in a row!), dropped a football on himself, gotten tangled up in a hammock, banged his thumb with a hammer twice, had a suction-cup toy arrow stuck to his forehead for an entire episode ... need I say more?
• Companion Cube: Jimmy is very attached to his controller, with which he operate the Tortuga's teleportation system. His present in the Christmas Episode is a drone to carry it around for him, and in the puffin episode, he hallucinates that it's talking to him.
• Cowardly Lion: Although he is a Non-Action Guy who is averse to fights in general, if a dire situation needs him in any way, he is willing to jump to the rescue despite his usual fears.
• Freudian Trio: With Aviva and Koki.
• The Good Captain: While he's often depicted as being something of a slacker, he is highly competent at his job.
• Hates Being Touched: Oddly, only with Aviva. Other characters have even made full body contact that he didn't look uncomfortable with, but he shrinks away from Aviva (except in "Masked Bandits" when she was behind him with her hands on his shoulders, and he had his hands on hers).
• Heavy Sleeper: The biggest example.
• Let's Get Dangerous!: Although he normally avoids threats like the plague, Jimmy rises to the occasion in "Hammerheads", fending off two Zachbots with the Tortuga's "Angry Turtle" Battle Mode and then deflecting one into a collision with another using a fishing rod. He takes down four of Zach's robots, leaving only one each for his friends to deal with.
• Non-Action Guy: The only member of the team who hasn't used a Creature Power Suit yet.
• Only Known by Their Nickname: His real name is James [insert last name here], but he is universally referred to by his nickname “Jimmy Z”.
• Only One Name: Subverted, at least he gets a letter. Poor Dabio and Koki don't even have that much.
• Trademark Favorite Food: Pizza. He's almost always seen eating it.
• Youthful Freckles: Has some freckles on his face.

Koki

Voiced by: Heather Bambrick (Until "Cats & Dogs"), Sabryn Rock ("Cats & Dogs" onwards)

• Action Girl: Not as overt as Aviva, since she prefers sneaking around when it comes to confronting villains, but she's definitely far from weak, as she can fight whenever she needs to, like in "Parrot Power".
• Badass Adorable: She's a lovably Sassy Black Woman who cares for the other crew members, and she is prone to Cuteness Proximity as well, but she is also a proven trickster who can mess up the villains' plans without them realizing, if she's not directly fighting them in her Creature Power Suits.
• Brainy Brunette: Her hair is black, and is great with computers, not to mention being capable of thinking outside the box as well.
• Communications Officer: She's responsible for keeping the Tortuga in touch with the Kratts, their kid supporters around the world, and the global communications network overall.
• Freudian Trio: With Aviva and Jimmy.
• The Heart: While she does have a hot temper sometimes, she ultimately serves as this to the team, holding them together.
• Only One Name: Her last name is unknown.
• Sassy Black Woman: She's black, and tends to be very snarky, particularly when either one of the Kratt brothers does something stupid.
• Tsundere: Type A.
• Wrench Wench: She's an engineer, just like Aviva, and she also serves as the team's computer expert, managing the communication systems of the Tortuga.
• Youthful Freckles: She has freckles on her face.

Villains

Donita Donata

Voiced by: Eva Almos

• Alliterative Name: Donita Donata.
• Bad Boss: Not very polite to her assistant, Dabio.
• Deadpan Snarker: Particularly when around Zach.
• The Fashionista: She's very successful with her animal-based line, and when frustrated starts sketching out ideas on a sketchpad.
• Head Pet: An awful lot of Donita's fashion ideas seem to consist of sticking a paralyzed animal on somebody's head.
• Idiosyncrazy: Donita's live-animal fashion line.
• Karma Houdini: Minor subverted one and a major Played Straight example:
  • For the minor subverted one, it's when her plans are foiled, she is often humiliated and is left to flee in defeat.
  • The major straight example, the methods she uses to obtain animals are outright poaching, but she never gets punished by the law for that.
• Modesty Shorts: In "Fireflies", it's revealed that she wears puffy green shorts under her crinoline intended for the fireflies she captured for her gown, which allows her to keep her modesty even if her plans for a firefly gown go south.
• Neat Freak: She has better tolerance on walking on nature than Paisley, but she is not a fan of messiness in general, which makes sense since she is a fashion designer (albeit not the most moral fashion designer out there.).
• Nothing Nice About Sugar and Spice: She's easily the most feminine of the villains, and she is obsessed with fashion, but she poaches and pose beams animals for her fashion line.
• Only Sane Woman: Despite being an Attention Whore, she's ironically the most levelheaded and intelligent of the original three villains, constantly being frustrated by Zach's childish demeanor, and tolerating Gourmand at best. Then Paisley Paver got introduced in later seasons and she took over as the sane woman. Although after Paisley defected, Donita is back to this role.
• The Paralyzer: Her weapon of choice is a "pose beam", a device that renders its target completely immobile and thus subject to Donita's whim. She uses it to incorporate animals into her fashions.
• Pink Is Feminine: The only female villain (until "Spirit Bear") travels in a pink jet or pink yacht. And even with Paisley's debut, she's still the more feminine of the 2 female villains.
• The Smurfette Principle: Before Paisley Paver was introduced, she was the only female villain on the show.
• Tomboy and Girly Girl: The fashion-obsessed Girly Girl to the building-focused Paisley's Tomboy.
• Villainous Crush: She has one on Martin, which is especially prominent when she calls him Martino, and is quite flirty with him.

Dabio

Voiced by: Cory Doran

• Affably Evil: He is working for Donita, but he is easily the kindest of the enemies the Wild Kratts face, even at his most competent, and it's implied he is working for her schemes because he wants to see her happy. Something that was lampshaded by Chris after he was unpose beamed by him in "Fire Salamander".
  Dabio (realizing Chris can't speak because he has been pose beamed earlier): Oh, uh, okay. Um, I'll unpose beam you for a minute but no funny business.
  (Dabio unpose beams Chris, much to Chris's relief, even as his shirt was dragged by Dabio)
  Chris: Thanks Dabio, you're a good guy.
• The Brute: More Affably Evil than the norm, but when he is a big and strong, but ditzy minion of Donita who is still willing to do her commands, he certainly applies.
• Captain Ersatz: He bears a strong resemblance to Kronk.
• Dumb Blonde: He has blonde hair, and is not very bright.
• Dumb Muscle: He is very strong, has big muscles, but is The Ditz.
• Evil Minions: But his evilness is disputed for reasons listed in the tropes.
• Manchild: To a degree, when he's not being an out and out idiot.
• Minion with an F in Evil: He's a bit of an incompetent sidekick towards Donita.
• No Celebrities Were Harmed: He's based on Fabio Lanzoni.
• Only One Name: Seems to be mixed with Nominal Importance.
• Perky Female Minion: Gender-Inverted Trope. While Dabio is not an outright Keet, he is more friendly and relatively cheerful (even if he's not the sharpest tool in the shed) compared to the serious Donita.
• Simpleton Voice: Speaks in this voice, fitting his status.
• Token Good Teammate: He is the most Affably Evil of the villains overall, and while he never really betrays Donita, he is shown to be kind to the Wild Kratts a few times, like in "Fire Salamander" where he willingly unpose beams Chris.
• Top-Heavy Guy: He has a large chest and very thin legs.
• You, Get Me Coffee: Donita always makes him do menial jobs for her.

Gaston Gourmand

Voiced by: Zachary Bennett

• Alliterative Name: Gaston Gourmand.
• Behind a Stick: "Platypus Café" and "Honey Seekers".
• Big Eater: Is implied to be this.
• Black Comedy Cannibalism:
  • In "Platypus Café" (his debut episode). While not necessarily played for laughs, he was planning on incorporating both Chris and Martin into his dish, but only managed to capture the former. He constantly refers to Chris as a “side dish” throughout the episode, going so far as to sniff him in order to decide which seasoning would go best with him. (While Chris suggested this in order to take advantage of and later trick Gourmand, it is noted that the latter did not hesitate to do so).
  • Subverted in "Happy Turkey Day," when Gourmand decides he wants to serve wild turkey for Thanksgiving and eagerly pursues Turkey!Martin, fully intending to cook him (subverted because Gourmand mistakes Martin for a real turkey due to not getting a good look at him and assumes that Martin is just a really big turkey).
• Cordon Bleugh Chef: He's a very good chef, but tends to cook specifically endangered animals.
• Evil Is Hammy: All the time.
• Evil Tastes Good: "Poached, roasted or barbecued... rare, endangered animals make the best food!" Gourmand singing to himself in "Platypus Café".
• Exotic Entree: His specialty as a chef.
• Fat Bastard: He's very fat, and he's also a villain.
• Fat Idiot: As mentioned above, he's on the chubby side, and not the most competent villain, though his nature knowledge is better than the other villains.
• Idiosyncrazy: Gourmand's endangered-only restaurant.
• Improbable Weapon User: Gourmand has dueled the Kratts with a variety of kitchen utensils, from a spatula to an electric eggbeater and even with sticky dough balls.
• Laughably Evil: Gourmand is this when not creeping out the viewers.
• Karma Houdini: Minor subverted one and a major Played Straight example:
  • For the minor subverted one, it's when his plans are foiled, he is often humiliated and is left to flee in defeat.
  • In another subverted example, he lost his chef license in the past for his illegal cooking of endangered animals (not like that stopped him).
  • The major straight example, the methods he uses to obtain animals are outright poaching, but he never gets punished by the law for that.
• The Nicknamer: Gives food-related nicknames such as "Wild Kratt Croutons", "Green Grape" for Chris, "Blueberry" for Martin, and "Avocado" for Aviva.
• Transforming Vehicle: His truck and boat unfold into a curtained-deck restaurant and kitchenette.

Paisley Paver

Voiced by: Julie Lemieux

^{Click to see Paisley after Our Blue and Green World (SPOILER WARNING!)}

• Alliterative Name: Paisley Paver.
• Dumb Blonde: Inverted, she has blonde hair, but she is the most levelheaded of the villains.
• Establishing Character Moment: Paisley's first onscreen appearance has her expressing disgust at nature and calling it useless.
• Good Costume Switch: After she joins the heroes in Our Blue and Green World, she starts wearing clothing with bright colors, round, pink glasses, and letting her hair down.
• Hartman Hips: In contrast to Aviva, who is a more realistic example, her waist is thin, but her hips are pretty wide and big.
• Heel–Face Turn: She defects from Zach's group after seeing and being amazed by the sea, as well as realizing why the Tortuga crew protect the Earth to begin with in "Our Blue and Green World".
• Neat Freak: She can't even step on unpaved ground without freaking out.
• Only Sane Woman: As the most levelheaded and intelligent of the villains, this trope serves as a side effect when she winds up surrounded by an Attention Whore who pose beams animals (Donita), a Dirty Coward with a high ego (Zach), and a Cordon Bleugh Chef who is also a Fat Idiot (Gourmand), which is best shown in "City Hoppers".
• Saving The Habitat: Where the show's other villains threaten animals directly, Paisley's goal is to pave over their natural habitat.
• Power Hair: She is the most serious of the villains (relatively speaking), the CEO of Pave Nature Inc, and sports short hair.
• Schedule Fanatic: She seems to judge the value of everything based on how much its sets back or speeds up her schedule.
• Shorter Means Smarter: Paisley is very short, and generally seems smarter and more levelheaded compared to the other villains.
• Silly Walk: Her legs blur and soft rhythmic sounds are heard when she walks on pavement.
• Soft-Spoken Sadist: Her voice is quiet and soft, even as she declares her intentions of destroying the environment and the homes of animals that live there.
• Tomboy and Girly Girl: The building-focused Tomboy to the fashion-obsessed Donita's Girly Girl.
• Totalitarian Utilitarian: A kid-friendly version. She believes that nature is inherently worthless, and is better off being developed for (in her view) the good of humanity.

Rex

Voiced by: Cory Doran

• Ambiguously Brown: It is unclear what ethnicity he is supposed to be.
• Crooked Contractor: He loves paving things over, and doesn't hesitate to attack the Kratts on Paisley's orders.
• Evil Minions: Paisley Paver's minion. He's actually quite more competent than Dabio and the Zachbots.
• Mr Fix It: Rex is a construction worker and dresses the part.
• Only One Name: Along with Koki and Dabio, he doesn't have a last name.
• Pragmatic Villain: He points out that Paisley's Mega-Storage facility probably won't have many customers, but goes along with her plan anyway because he likes laying pavement so much.

Zachary “Zach” Varmitech

Voiced by: Zachary Bennett

• Alliterative Name: Averted, he is the only main villain who's name doesn't feature that. (Dabio and Rex don't count since they are just assistants to Donita and Paisley respectively, and have no known last names.)
• Arch-Nemesis: To Aviva.
• Attention Whore: He's always trying to find some way to be famous.
• Bad Boss: To the Zachbots.
• Butt-Monkey: It's karmic, though.
• Buffy Speak: Animals are always (feature)-thingies: Seal-thingies, warty-thingies…
• Character Catchphrase: "I'll get you, you Wild Ratts!"
• Child Hater: With a Freudian Excuse.
• Competition Freak: Typically with Aviva, on terms of who is the better inventor.
• Corrupt Corporate Executive: Is willing to cross the Moral Event Horizon to achieve his goals, as shown by his numerous attempts to either maim or outright kill the Kratt brothers.
• Dick Dastardly Stops to Cheat: In "Back in Creature Time," Zach manages to infiltrate the Tortuga and captures Koki and Jimmy. After that, Zach uses the Time Trampoline to travel to the past where the other Wild Kratts are. Zach states that he can now go back to the present with the Trampoline piece, thus trapping the Wild Kratts in the past forever, but what fun would that be if he doesn't tell them that? Needless to say, the heroes foil Zach's plan and everyone returns to the present.
• Dirty Coward: Any time any kind of threat shows up, he squawks in terror and either sics his robots at whatever it is or runs off in a panic.
• Eerie Pale-Skinned Brunette: He has very pale skin, black hair, and is evil.
• Evil Genius: A wealthy robotics inventor, he's the CEO of his own multi-million dollar company, Varmitech Industries.
• Evil Is Hammy: When things don't go his way.
• Evil Is Petty: Sometimes Zach has no real reason to do acts of villainy other than to ruin the Kratt Brothers' fun. Also, he gets annoyed if someone unknowingly asks a question that he already asked, even though they (obviously) didn't know he already asked the same question.
• Freudian Excuse: See "Never My Fault".
• Foil: To Aviva, both are genius inventors that make robots based on animals, pilot large flying machines, and can be a bit self absorbed sometimes, but while Aviva makes power suits based on animals to save animals, Zach basically brainwashes animals into doing his bidding, Aviva is willing to get her hands dirty should the situation come to that, while Zach will laze around and let his robots do the work for him and will run off the second that fails.
• Gadgeteer Genius: Subverted since the Zachbots (and all his guardbots, really) are used for Mundane Utilities. Sounds like if Tony Stark was a villain.
• Gotta Have It, Gonna Steal It: There's nothing Zach would love more than to steal the Wild Kratts' technology for himself, especially the secret behind the Creature Powers, mainly because he doesn't have the skill to invent them himself, yet he considers himself to be a better inventor than Aviva.
• Greed: His main motivation for his animal capturing scheme is to make money off of them, even though he's already rich, he wants to be really rich.
• Inferiority Superiority Complex: Constantly insists that he is and always has been superior to Aviva in terms of inventing (despite the fact that he lacks the knowledge to invent some of the great things Aviva has invented), and often times, refers to himself as "The world's greatest mind/inventor!".
• Karmic Butt-Monkey: Really, the mishaps he suffers constantly is his own fault since he keeps trying to harm animals and trying to get revenge on the bros for such petty reasons.
• Kick the Dog: Zach has taken baby animals captive a few times in order to get what he wants.
• Know-Nothing Know-It-All: He thinks that he knows plenty about the animals that he involves in his schemes but in reality, it's laughably obvious he hardly knows a thing.
• Laughably Evil: The biggest example.
• Manchild: While it's unknown how old he really is, judging by the flashback in "Tazzy Chris", it is safe to assume he is around the same age as the brothers, both of which are adults, but Zach is less mature than both of them.
• Mind Control: By using a Mind Control device for Unwilling Roboticisation. The animals always have Mind-Control Eyes.
• Momma's Boy: When Martin turned off the power to Gourmand's restaurant in "Platypus Cafe," Zach got scared and even called for his "mommy".
• Narcissist: Zach loves himself a lot, to the point he had his computer refer to him as "My Greatness" as shown in "Osprey," and got lured in by a gold coin with his face on it in "Rocket Jaw: Rescuer of the Reef," this example overlaps with Greed.
• Neat Freak: "Help! I'm CONTAMINATED! Somebody SAVE me!"- "Let the Rhinos Roll!", after being thrown into the mud pit.
• Never My Fault: "They made me lose! I never lose!"- "Bass Class". Also, his Freudian Excuse is that the Kratt Brothers wouldn't let him make robots out of animals when they were kids, and this is why he A- hates kids, B- hates the brothers, and C- is a villain at all.
• No Celebrities Were Harmed: His voice is a Gilbert Gottfried impression. And also, his character is based from Elon Musk.
• Psychopathic Manchild: He is psychopathic and is definitely an immature, whiny, and cowardly egomaniac.
• The Resenter: Is jealous and resentful of the success of Aviva's inventions to the point that he seeks to steal them for his own purposes several times.
• Revenge Before Reason: Y'know, if he'd leave the animals alone and stop trying to get revenge on Aviva and the bros, all his problems would disappear. It's that simple (sad, miserable, pathetic wimp).
• Rich Bastard: He's callous, arrogant, wants money, and already being rich is not gonna stop him from wanting to be more rich.
• We'll See About That: His usual reason for villainy. He even quotes this once.
• Why Did It Have to Be Snakes?: Or any animal, for that matter. It's odd - he's at once terrified of animals, yet uses them for his robots.

Zachbots

• A.I. Is a Crapshoot: The Zachbots often misunderstand or mishear Zach's commands for example, failing to understand figure of speech.
• Do-Anything Robot: The Zachbots come with all sorts of arrays of utility hands (i.e. fan, cleaning brush, metal detector, spinning saw, disintegrator, spy camera, and shears, to list a few).
• Evil Minions: Laughably Evil, but evil.
• Expy: Of the Jack-Bots.
• Literal-Minded: To the point of being Phrase Catchers for Zach's "I didn't mean literally!".
• Mecha-Mooks: Zach's personal minions... and also, his servants.
• Telescoping Robot: Mixed with Mundane Utility — attachments include an umbrella, a fishing net, and ointment. Yes, ointment. Possibly Do-Anything Robot.
• You, Get Me Coffee: Zach typically has them do the work that he's too lazy to do or doesn't want get his own hand dirty doing it.
