Characters / Oggy and the Cockroaches

This is the list of Oggy and the Cockroaches characters. There are some minor spoilers ahead and, if you care, read with caution.

---

In General

• The Chew Toy: They're characters in a slapstick cartoon. Do the math.
• Four-Temperament Ensemble: Between the four eponymous characters
  • Oggy: Phlegmatic. The Nice Guy, who tends to be accomodating and get along with one-shot characters. He can be a bit indolent and lazy, but very dedicated with his loved ones;
  • Dee Dee: Sanguine. The most immature and childish of the crew, but very energetic, lively, quirky and brave, as he never pulls himself back in front of a challenge;
  • Joey: Choleric. The smart, strong-willed leader of the Cockroaches, but impatient and prone to violent and irate outbursts;
  • Marky: Melancholic. The shy, patient and sensitive member of the group.
• Only One Name: Most, if not all, characters just have one name.
• Nice Mean And In Between:
  • Nice: Olivia, Oggy, Piya;
  • Mean: Lady K, The Cockroaches, Bob;
  • In Between: Jack, Monica;
• Sadist: They sure enjoy hurting each other. Averted with Olivia.
• Silent Snarker: All characters will often point out whenever one of them strands into Cuckcoolander territory via gestures.
• White Gloves: All animal characters sport white fur on their hands which resemble white gloves. Or they flat-out sport them.

The Cat Duo

General tropes

• Amazing Technicolor Wildlife: Oggy's blue, while Jack is green.
• Butt-Monkey: Both cats suffer a lot of Amusing Injuries, especially Oggy.
• Fur Is Clothing: They sometimes reveal their underwear if their fur is removed.
• Gag Nose: Their fairly silly-looking noses, especially Oggy's, have supplied the show with several of its jokes.
• Hated by All: In "Fake News", thanks to Joey manipulating them into thinking they're scumbags. On a normal day, with a few exceptions, they don't mind the cats as long as they don't provoke them.
• Heroes With Bad Publicity: Invoked by Joey in "Fake News", as he tricks the public into despising Oggy and Jack.
• Inelegant Blubbering: They both can literally cry like a baby at times. Oggy does this slightly more often, though.
• Official Couple:
  • Both Oggy and Olivia are confirmed to be in love.
  • Jack is confirmed to be in a relatinship with Oggy's twin sister, Monica.

Oggy

Oggy

The titular protagonist, he is a diplomatic, sometimes lazy and an easy-natured cat who is the constant victim of the Cockroaches. He spends his time chasing and catching the cockroaches, but somehow developed a love/hate relationship with them.

---

• Amazingly Embarrassing Parent: Not a parent himself, but he acts likes an embarrassing father towards Jack's nephew.
• Ambiguously Bi: There were episodes where Oggy showed attraction to women, and others were he clearly ogled men. In "Oggy's Night Out", he and Jack went to eat on a classy restaurant, and Oggy was carrying a purse. Season 4 averts this by having Olivia be his only romantic interest.
• Arch-Enemy: It's seldom when he and the roaches never fight in an episode.
• Badass Adorable: Oggy is cute-looking, but isn't afraid to fight back.
• Berserk Button: God help you if you break his figurines. The roaches breaking off an ear from one of them was enough to send himm into a Heroic BSoD... but when his robot clone threw Bob into all of them and broke them, not even Bob was spared from Oggy's wrath.
• Beware the Nice Ones: While Oggy is generally a Nice Guy, he usually will not hesitate to fight back against the cockroaches when they harass him.
• Big Eater: Oggy is usually eating something in most of time, and his fridge is filled with tons of food.
• Blue Is Heroic: His fur is blue, and he is depicted as being more heroic in later seasons.
• Buffoonish Tom Cat: A lazy cat who is also a Manchild, an occasional Cloud Cuckoo Lander and is very slapstick-prone due to his clumsiness or sheer silliness.
• Bullying a Dragon: Usually, provoking Bob into beating him up is either by accident or the cockroaches' doing. On rare occasions however, Oggy will make the mistake of messing with him, as shown in "TV Obssession" where he steals his car and later locks him in the bathroom to watch his TV.
• Butt-Monkey: He is the most liable to suffer misfortunes in this cartoon, like being tricked by the cockroaches and being beaten by Bob. This dwindled down slightly in Season 4.
• Can't Live with Them, Can't Live Without Them: His relationship with the cockroaches. He hates them but can't live without them. Becomes a plot point in "So Lonely".
• Cats Are Lazy: He's a cat who mostly likes to watch TV, eat, and occasionally listen to music.
• Cats Are Mean: Zigzagged. While Oggy is a cat, he's generally a Nice Guy but he's occasionally shown to have a mean side. It's especially when he's an episode's antagonist (e.g. "Take Cover").
• Chick Magnet: Invoked by Joey in "Face Off"; he causes Oggy to get a Surgical Impersonation that gives him a celebrity's face. That causes all nearby females to be all over him.
• Cloudcuckoolander: Sometimes he's shown to live in his own little world.
• Crazy Jealous Guy: If your girlfriend were to be stolen by one of your nemeses, you'd be jealous too.
• Crouching Moron, Hidden Badass: While Oggy is often attacked and ridiculed by the Cockroaches, even they are shocked sometimes at just how often he manages to outsmart them.
• Determinator: Oggy will often go to great lengths to get revenge on the Cockroaches.
• Enemy Mine: Oggy allied with the cockroaches in some episodes, to screw enemies in common.
• Girls Love Chocolate: Gender-inverted, as a couple episodes show he likes chocolate.
• Godzilla Threshold: If you are a major Jerkass to the point of greed, chances are he will get the cockroaches to help him. Jack and Bob learned this the hard way.
• Half-Identical Twins: With his twin sister Monica.
• Heroic BSoD: Briefly in “Black and White” when Oggy lost his colors, due to an accident with the washer.
• Inconsistent Spelling: His name, Oggy, is spelt as "Oggi" in the Finnish version and "Ogi" in the Serbian one.
• In Touch with His Feminine Side: Has a few feminine traits, like the fact he carried a purse as he went to a fancy restaurant with Jack, in "Oggy's Night Out".
• Iron Butt Monkey: He's been run over by cars, trains, and even airplanes, crushed by a rocket ship, incinerated, shot by a missile, fallen into radioactive waste, and is caught in an explosion nearly every episode. It's safe to say that Oggy is pretty much indestructible.
• Jerkass Ball: Although rare, he is sometimes the one to instigate the fights between him and the cockroaches.
• Jerk with a Heart of Gold: He is the least “jerk” and the most “heart of gold” in comparison with Jack and the cockroaches. Generally, he only reacts in response for cockroaches' provocations.
• Lazy Bum: Most of the time, Oggy is watching TV.
• Leg Focus: Played for Laughs, but once or twice he's temporarily gained long, well-toned legs with the camera giving a close-up of them.
• Living with the Villain: He knowingly lives with the roaches, the show's primary villains, although he's one of the main heroes.
• Manchild: This is an obvious case in "Soldier for a Day", for example, where his room is shown to be full of children's toys despite him being an adult.
• Masculine Girl, Feminine Boy: The Feminine Boy to Monica's Masculine Girl.
• Moment Killer: A comical example in "Just Married!"; When Jack and his Love Interest are about to kiss, Oggy interrupts it via going full-on Ocular Gushers.
• Nice Mice: He's normally a Nice Guy and, while it didn't last, he gets turned into a mouse in "Witch Hunt".
• No Celebrities Were Harmed: In the Hindi dub, his voice is a mimicry of Shah Rukh Khan.
• No-Holds-Barred Beatdown: Not even he will shy away from pulling these when sufficiently pushed; he's beaten up Jack at least twice, and not even the cockroaches are spared from this.
• Ocular Gushers: Most characters literally cry rivers in this show, but it's most noticeable with Oggy due to just how often it happens.
• Older Hero vs. Younger Villain: An inverted example; according to "It's a Small World" and "Itsy-Bitsy Oggy", Oggy is younger than the cockroaches.
• O.O.C. Is Serious Business: Ordinarily, he doesn't hesitate to retaliate when the cockroaches bug him. But, while potentially Played for Laughs, he gets so lost in thought in "Jealousy" that he doesn't even react to them inflicting Amusing Injuries on him.
• Papa Wolf: It's a terrible idea to mess with his baby dragon in "Oggy's Dragon".
• Prone to Tears: It doesn't take much to upset him to the point of tears. Interestingly, he will rarely cry in response to physical pain despite the amount of over-the-top Amusing Injuries he goes through, but what would be a minor annoyance to anyone else has the potential to get his Ocular Gushers flowing.
• Relationship Upgrade: He and Olivia eventually get married.
• Spoiled Brat: He behaves like one in "Oggy's Got Talent!" as he acts like he's a haughty king who demands stuff only he cares about. When he doesn't get what wants, he starts pouting, and shows no gratitude for when he actually gets it.
• Strong Family Resemblance: Sorta. In "Nine Months and Counting", the babies he imagines having look exactly how he looked that age.
• Sympathy for the Devil: It's very rare, but there are instances in which he sympathizes with one of the cockroaches.
• Throw the Dog a Bone: For the first three seasons, Oggy in seasons 1-3 was usually portrayed as a lot unluckier, suffering repetitive bullying and physical harassement by the Cockroaches and/or Bob on a near-daily basis, even losing a good deal of battles with them. However, from Season 4 onwards, his Butt-Monkey status was toned down: Oggy triumphs over his nemeses much more often, and gets beat up way less often by Bob (and even bit back at him more than once). To top it all off, most importantly, he now has a consistent girlfriend in the form of Olivia.

Jack

Jack

Oggy's cousin, who is sometimes around Oggy to help him take care of the troublesome cockroaches with his inventions.

---

• Berserk Button: Do not interrupt him when he's watching soccer on TV. Oggy learned that the hard way in "Penalty Shot" and its remake "Soccer Fever" by pulling the plug on a game Jack was watching.
• Big Brother Instinct: A figurative example. On occasions where Oggy proves to be incapable of handling the cockroaches by himself, Jack is usually there to help him out. "Flower Power", "The Rise and the Fall" and "All Out of Shape" are prime examples of this.
• Butt-Monkey: Not frequently like Oggy, but when something happens to him, it's usually much worse than the treatment Oggy gets.
• Cats Are Lazy: In episodes like "Night Watchmen", "Dump the Roaches!" and "Grease Monkey Oggy".
• Cats Are Mean: Downplayed. Jack is a cat who's more of a Jerk with a Heart of Gold, but he can have a mean streak, especially towards the cockroaches.
• Characterization Marches On: Jack, in earlier seasons, was more of a Mad Scientist than the tough type he is today. In later seasons, the "mad" part was dropped. Later episodes like "Oggy's Exoskeleton" have started to bring this trait back though.
• Cool Car:
  • Jack doesn't just have a car; it's a monster truck!
  • He also got one in "The Pumpkin that Pretended to be a Ferrari", courtesy of a fairy turning a random pumpkin into the ride of his dreams. Unfortunately, the spell eventually wore off, reverting the car back to its original pumpkin form... with Jack and his date still inside. Fortunately, Oggy carves them out.
• Crazy-Prepared: At times. He has a lot of stuff with him to be prepared.
• Depending on the Writer: Depending on how involved the plot of an episode requires him to be, he will either have his own home and visit Oggy, or just implied to be living with Oggy as a roommmate.
• Dreadful Musician: A few examples:
  • In the movie's Victorian segment, he (as Sherlock Holmes) plays the violin terribly, in a stark contrast to how Holmes himself usually plays.
  • During the Greek Odyssey episodes, it's a Running Gag for Jack to play the harp (badly) and sing (really loudly), greatly disturbing Oggy and Olivia.
• Drunk with Power: In "The Dictator", where he lets the success of capturing the cockroaches go to his head and becomes an arrogant dictator.
• Gadgeteer Genius: He makes a lot of machines. Though by later seasons, this appears to have dropped.
• Jerk with a Heart of Gold: He always pursues the cockroaches even for no reason and he occasionally antagonizes and uses Oggy and his properties for his own profit, yet several episodes show that he truly does care about Oggy's well-being, and he harbors an unrequited soft spot for Oggy's sister Monica, his future girlfriend.
• Laser-Guided Karma: Many of his plans to get rich or win backfire because he becomes meaner than usual. A notable example is in “Life's A Beach” when Jack uses Oggy's house and pool for his business without asking him permission for that and ends the day being beaten by his customers and getting struck by lightning several times.
• No Celebrities Were Harmed: In the Hindi dub, his voice is a mimicry of Sunny Deol.
• Only Sane Man: Occasionally, he'll play the Straight Man to Oggy's oblivious or immature behavior, like in "Oggy and the Babies" (where he quickly realizes the "baby kittens" delivered to Oggy's house are the roaches in disguise), and "TV Obsession" (where he shows disapproval at Oggy's television-deprived behavior and keeps a level head through his screentime).
• The Slacker: He has a tendency to sleep during his jobs, which usually forces Oggy to be the only one working, as shown in the aforementioned episodes above.
• Why Did It Have to Be Snakes?: He has a fear of heights as shown in "The Lighthouse Keeper".
• Yellow Eyes of Sneakiness: His yellow irises are occasionally seen and he's definitely more conniving than Oggy.

The Cockroaches

Tropes applying to all

The cockroach trio who live in Oggy's house and are the titular villain protagonists of the series. They usually are the main cause of Oggy and Jack's misfortunes, though their shenanigans are sometimes directed towards someone who deserves it.

---

• Adaptational Nice Guy: While they're still mean-spirited pranksters like they were in the original, Next Gen makes them a tad less sadistic and more inclined to get along with Oggy and Piya. In particular, they almost never directly harm her, in contrast to how they give tons of trouble to Oggy in the original. Their pranks are less destructive as well compared to the parent cartoon.
• Adaptational Villainy: The trio were never particularly nice. However, in the movie's third section, their ancestors prove to be even worse, as they attempt to murder Queen Victoria and several innocents.
• Adaptation Dye-Job: Played straight with Dee Dee, yet zigzagged with Marky and Joey in the comics. Despite Dee Dee's eyes being green in the show, they usually appear yellow there. However, Marky's eyes can both be either pink (like they are in most episodes of the show) or yellow. Joey's eyes can also either both be yellow or one yellow with the other being pink, despite him having the latter in most of the cartoon.
• Ambiguously Related: They're generally together, very slightly resemble each other, and are close buds. According to at least one official description for "Roachy Redneck", the redneck cockroach who visited them is their cousin. Ditto with the termite in "Termite-ator". However, official descriptions for later episodes refer to them as friends. Interestingly, one official description for "La Cucaracha" states La Cucaracha is Joey's cousin but not Marky and/or Dee Dee's.
• Anti-Hero: In a very small group of episodes, usually leading up to a Pet the Dog moment with Oggy.
• Anti-Villain: It varies. Some episodes give them at least fairly reasonable motivations behind their actions. For example, in "Oggy's Dragon", they try to nab the titular dragon to start a fire. In freezing weather. When they couldn't get a fire started. And this episode occurred before air conditioning was invented. Other times, however, it's purely For the Evulz.
• Arch-Enemies: Anyone who steals from, provokes, and tries to ruin Oggy's life as much as they do deserves this title.
• Aw, Look! They Really Do Love Each Other: They constantly bicker, fight, and hit each other for the most frivolous reasons, but they often stick together, and in many episodes, like in "Caviar on the House!", they show they truly care about one another.
• Bad Guys Play Pool: They're a Terrible Trio who've played pool at least once, more specifically in the episode "Paper Chase".
• Beard of Evil: Santa Claus would be proud of their white beards in the first episode of Oggy and the Cockroaches Next Generation. Doubles as Animal Facial Hair since they're cockroaches.
• Beware the Silly Ones: They're immature, silly, naughty, and sadistic cockroaches, so crossing them is very ill-advised unless you want to discover how mean they can get.
• Big Bad: They're almost always the leading problems in every episode.
• Big, Thin, Short Trio: Dee Dee is the big, Marky is the thin and Joey is the short.
• Birds of a Feather:
  • The fact they're all sadistic and mischievous Psychopathic Manchildren who love tormenting other characters (especially Oggy and Jack) seems to be a key reason why they usually get along.
  • Their pleasure-seeking, childlike personalities seem to be why they get along well with Piya (a seven-year-old who acts her age) when they aren't fighting.
• Bitch in Sheep's Clothing: If the episode calls for it, they can turn on the charm and play on everyone's sympathy in order to achieve their goals ("Jealousy", "Roach Vision", "Fake News"...).
• Buffoonish Tomcat: When they're turned into tomcats in "The Witch Hunt", the cockroaches (especially, but not exclusively, Joey) still aren't immune to Amusing Injuries. Also, Dee Dee and Marky occasionally act like a Bumbling Henchmen Duo.
• Can't Live with Them, Can't Live Without Them: Just like how Oggy can't live without the roaches, they can't live without him. In "Moving Out", they actually cry after realizing that Oggy truly is gone from the house. Then Marky and Dee Dee start losing it and begin hitting themselves with Oggy's fly swatter just to relive their memories of him squashing them.
• Cats Are Mean: Generally averted as they obviously aren't cats. However, they get turned into cats in "The Witch Hunt" but continue being a Terrible Trio.
• Color-Coded Characters: Downplayed, while they do have different designs to make them stand out, sometimes the animators tend to mix things up by giving them the wrong color schemes, this especially happens with Dee Dee and Joey, who are both small in size compared to Marky, who has a different set of antennas as well.
• Conveniently Cellmates: When they're in prison in The Movie's "The Incredible Oggy Watson" section and the episode "Sheriff Oggy", they're conveniently sharing a cell together.
• Creepy Cockroach: Downplayed mostly, as they're merely just annoying little fellows who take delight in screwing with Oggy.
• A Day In The Lime Light: "High Flyers", "Saving Private Dee Dee" and "Shoplifting" are the only episodes to primarily focus on the Cockroaches without Oggy also playing a major role.
• Dirty Coward: They love to act tough and make Oggy, Jack or any innocent victim suffer their machinations, but the minute they lose control of the situation, it's either fleeing in terror or begging for mercy they are less likely to receive. Averted with Dee Dee alone, as he proved to be braver than expected, like trackling bigger enemies, or Comically Missing the Point when he is in danger.
• Dub Name Change: Their names are changed in the Hindi dubs.
  • In the Nickelodeon dub, Joey is called Chotu but Zaplu in the Cartoon Network dub.
  • In the Cartoon Network dub, Dee Dee is named Paplu. However, in the Nickelodean dub, he's called Chotu.
  • Marky's name is Taplu in the Cartoon Network dub but Lambu in the Nickelodeon one.
• Even Evil Can Be Loved: Particularly with each other; while all three of them are shown to be cruel, they clearly do love each other.
• Even Evil Has Standards: Although all of them are generally shown to be villains, they do have some standards.
  • They seem fairly appalled in "Oggy and the Babies" when Oggy swats multiple kittens with a broom and Jack laughs while he does so. Granted, it didn't last long.
  • In "Scaredy-Cat", Dee Dee and Marky look horrified when they think a swamp monster is going to attack Oggy. Subverted in Joey's case; he initially looks disgusted... but then he happily puts on 3D glasses.
  • Stealing stuff from Oggy? Not a problem with Dee Dee and Marky. Stealing a valuable item from a beautiful celebrity? Joey finds out the hard way that's one thing they won't do or stand for.
  • A strange example in "Oggy's Teddy Bear"; Marky is horrified over Joey and Dee Dee using a teddy bear as a tennis ball.
• Everyone Has Standards: Some instances have at least one of the cockroaches find something (non-villainous) distasteful.
  • Marky gets disgusted with the smell of some gas in "French Fries".
  • In "The Rise and the Fall", the trio finds it ridiculous that Jack is building a skyscraper for himself.
  • All of them find Oggy's odor revolting in "Deep End".
  • In "Virtual Voyage", Joey clearly didn't want to ride the word "Bottom" for a fairly-easy-to-guess reason.
  • Possibly Played for Laughs in "Beachcombers"; the roaches find a Fan Disservice-y picture of a fish woman disgusting.
  • Played for Laughs in "Roachy Redneck", the smell of their redneck cockroach's stinky cheese grosses them out so much, it makes them faint.
  • Dee Dee and Marky are clearly repulsed by Oggy's foul smell in "The Roaches Seize the Castle" after he went through some sewers.
  • Even Joey and Dee Dee eventually begin to find a conquistador annoying in "Gold Fever".
• Evil Feels Good: It's obvious they think so; they clearly enjoy most of their cruelties.
• Evil Gloating: When things are going their ways, the cockroaches love gloating. Probably invoked so they can troll other characters.
• Evil Is Petty: They sometimes seek petty revenge on Oggy or Jack (particularly the former) just for messing with them. Even when it's unintentional.
• Evil Laugh: Almost every one of their appearances will involve them laughing. Even at the beach and as ghosts.
• Evil Old Folks: As revealed in "The Time Machine", they try continuing to be a Terrible Trio after they grow old.
• Evil Plan: While exactly what it is depends on the episode, their most prominent goal is that they want to ruin Oggy's life.
• Evil Smells Bad: Although it's Played for Laughs, they've all been on the receiving end of Smelly Feet Gags at least once. Also, "It's a Small World" reveals Marky's breath smells horrible.
• Extreme Doormat: How Marky and Dee Dee put up with Joey's abuse in later seasons is questionable for the most part, though it's downplayed in that if Joey goes too far with his schemes, they'll gladly stand up to him.
• For the Evulz: When they aren't raiding the fridge, they are wreaking havoc on the cats for fun.
• Fur Is Clothing: Like Oggy and Jack, their underwear or their toes can be exposed if their scales are removed in some episodes.
• Gang of Bullies: Especially towards Oggy. In fact, "It's A Small World" establishes that they have been harassing him since he was a baby.
• Girls Love Chocolate: Gender-swapped. "Bitter Chocolate" shows these guys like chocolate.
• Godzilla Threshold: Oggy's go-to guys in the event his friends or neighbors become greedy jerkasses. Depending on the episode, he will pay them for the job.
• Graceful Loser: They're surprisingly this in "Masquerade". Despite causing a Nice Job Fixing It, Villain moment and Joey initially being fairly upset about losing, all three of them take their loss well. Namely when Marky points out they can swim in the huge pile of confetti they accidentally helped cause.
• Hope Crusher: They live to crush other characters' hopes, especially Oggy and Jack's.
• Jerkass: The cockroaches are the biggest jerks in the cartoon. Most of time, they are annoying Oggy and Jack for fun. Even Bob is a victim of their actions, sometimes.
• Jerkass to One: Other characters are fair game to them and their tricks, but they love to target Oggy and Jack the most and make them the butt of all jokes. Out of the two, Oggy is the one whom they bully more by having the misfortune of sharing a house with them.
• Karma Houdini: Any episode where they don't suffer from their Laser-Guided Karma. Especially notable in the comics where Oggy wins only once.
• Karma Houdini Warranty: Big time in season 4^note since they suffer from Laser-Guided Karma in almost every episode. This also continues onto season 5, although in a much more downplayed manner.
• Karmic Butt-Monkey: Zigzagged. They don't always get hit by karma. Other times, it has struck them several times in a variety of ways. They go from simply being crushed by Oggy or putting them inside a jar, to being repeatedly smashed by a wooden mallet, thrown into a sausage grinder, getting Eaten Alive, having their bodies inflate until they explode, getting frozen into a block of ice, being used as teeth, or getting sucked into a black hole. However, there are some instances in which something bad happens to them and they don't deserve it, like in the final episode of Oggy and the Cockroaches Next Generation when a bratty Jerkass tries to kidnap them. That time wasn't so egregious, though, as they did get free.
• Leitmotif: Their theme is a jester-like melody that sees several variations through the series' run.
• Lethally Stupid: Dee Dee is particularly prone to this, but also Marky andJoey have also had their stupid moments which have costed him victories.
• Light Is Not Good: They sport White Gloves and are some of the cartoon's most malicious characters.
• Might as Well Not Be in Prison at All: They outright get thrown in prison in The Movie's third segment, which doesn't hamper them at all. Indeed, it was actually part of Joey's plan.
• Moment Killer: They're the "Deliberate Destruction" type towards Jack and his Love Interest in "Just Married"; they deliberately ruin several of their romantic moments to troll them.
• Mook Maker: They create Mooks for themselves using a magic pencil in "A Magic Pen", though Joey seems to be the biggest offender.
• No Celebrities Were Harmed: The roaches are named after members of the punk band The Ramones.
• Not Me This Time: Make no mistake, they're guilty of many of Oggy's misfortunes. However, occasionally they are actually not the ones to blame, despite the blue cat thinking otherwise. It's even a Plot Point in one Oggy and the Cockroaches Next Generation episode in which he thinks they broke a picture, when it was actually Piya.
• Older Hero vs. Younger Villain: An inversion. While the cockroaches are the series' most reoccurring villains, "It's a Small World" reveals they're older than Oggy.
• Older Than They Look: They look like they're around Oggy's age. However, during the flashback in "It's a Small World", they still look and act the same while harassing Oggy when he was an infant. Possibly retconned as of "Let's Party, Guys!", wherein Joey's birthdate is revealed to be June 15, 1991 (which would make him 21 years old at the time that episode aired).
• Pet the Dog: It's rare, but they have their moments where they do care about Oggy when they're not trolling him.
• Pick on Someone Your Own Size: They've been antagonizing Oggy since he was a kitten according to "It's a Small World", although they were adults at the time.
• Psychopathic Manchild: They're a Terrible Trio of adults who frequently act like naughty boys. Compared to the other two, Joey is a Type C. While he's usually shown to be smarter than them, he's often as childish as they are and he sometimes throws tantrums when things don't go his way.
• Psycho Pink: Male examples.
  • Joey has a pink eye, a cruel nature, a pink body (albeit of a different shade), and he loses it in "Oggy's Double".
  • Marky's eyes are pink and, while he's transformed into a cat in "The Witch Hunt", he has patches of pink fur.
  • Dee Dee briefly sports scuba gear with some pink in "Mayday! Mayday!".
• Pragmatic Villainy: In "Working Cat", the trio help Oggy get a new job through cheating after his debts become too high and he runs out of food for them to eat. Although, it turns out that the job Oggy was given is actually pest control!
• Real Men Hate Sugar: Inverted; these guys aren't above eating sugar.
• Sanity Slippage: Not that they lasted.
  • After Oggy moves out in "Moving Out", Dee Dee and Marky begin flipping out and start hitting themselves with his flyswatter.
  • Doubles as a Villainous Breakdown in "Oggy's Double"; after Oggy and his double completely outsmart him, Joey really loses it and goes Laughing Mad.
• Screams Like a Little Girl: They take this trait in later episodes.
• Secondary Color Nemesis: They all have black, Joey is purple, Marky has green, and Dee Dee is orange. Also, they're all villains.
• Shipper with an Agenda: A villainous one in "A Jealous Guy". They give Oggy photoshopped images of Joey and Olivia being a couple to trick him into thinking they're dating. They did this as revenge and to mess with his mental health as he's got a huge crush on Olivia.
• Sinister Schnoz: They all have long pointy noses and are Oggy's main nemeses.
• A Taste of Their Own Medicine: Several episodes end with Oggy and/or Jack enacting their revenge on them by simply using the same tactics that the Cockroaches used on them during the episode.
• Tennis Boss: A non-Video Game example in "Cockroaches Play Cricket"; they and Oggy fight via trying to knock a coconut at one other like they were playing Tennis.
• Terrible Trio: All three of the cockroaches are naughty, cruel, and slobbish.
• Tom the Dark Lord: They're the main villains of this series...and their names are Joey, Marky, and Dee Dee.
• Troll: They cause mischief and antagonize Oggy and Jack a lot.
• True Companions: As mean as they are to Oggy, they are the best of friends with each other.
• Ungrateful Bastard: Occasionally. In "Priceless Roaches" for instance, Oggy risks his life to save the trio from being imprisoned in China but they show no gratitude to him whatsoever. In return, however, Oggy makes them his prisoners.
• Villainous Breakdown: They have several of these. For example, they fall apart in "The Patient" after learning Oggy was going to inject them with a rectal thermometer larger than them.
• Villainous Glutton: All three of them have massive appetites, with Dee Dee easily being the most gluttonous. They're also the series' main villains.
• Villain Protagonist: Should the episode mainly focus on them, they're usually this.
• Villains Out Shopping: Or playing soccer, card games, etc.
• Villains Want Mercy: Although they're a textbook Terrible Trio, they outright plead for mercy several times. For instance, they beg Jack to spare them in "Oggy and the Babies".
• Villains With Good Publicity: All three roaches have experienced this.
  • In "Fake News", the Joey and Marky become In-Universe examples of The Woobie.^note Technically, they'd be Jerkass Woobies. However, their sympathizers don't seem aware of the foremost part. It's justified as the former manipulated them.
  • Apparently in "A Night at the Opera", Dee Dee becomes a well-liked opera singer. Probably justified because he's surprisingly talented at singing opera. Also, the public didn't seem aware of his villainous traits.
• Villain Team-Up: They team up with Oggy's "Bad Angel" in "Green Peace".
• White Hair, Black Heart: They get white Animal Facial Hair, namely beards, in the first episode of Oggy and the Cockroaches Next Generation.
• Would Harm a Senior: In "Oggy's Grandma", Joey shows Oggy's granny that Amusing Injuries are equal-opportunity in this show. Later, Dee Dee and Marky also try to toss paint buckets at her.
• Yank the Dog's Chain: In "Let's Party Guys!", after having a terrible party, the Cockroaches notice that both Oggy and Jack seem to have bought a present for Joey's birthday! And it's a flyswatter! Which they then use to squish the Cockroaches.
• Your Size May Vary: In "From Mumbai with Love", they pull a Totem Pole Trench to impersonate a cricket player. It inexplicably allows their combined heights to match a human's height and Joey's head and arms get human proportions as well. When their disguise is blown, they immediately revert to their usual size.
  • Marky and Dee Dee do it again in "Back to the Past", this time without Joey to add some extra height. They still manage to look human-sized nonetheless.

Joey

Joey

A pink-bodied, purple-headed roach with a pink right eye and a yellow left eye, Joey is the self-proclaimed leader of the roaches. Even though he's the smallest roach in the gang, most of the time he's the brains behind the operations.

---

• All of the Other Reindeer: None of the summoned grasshoppers in "Oggy and the Grasshopper Cloud" want anything to do with him.
• Amnesiacs are Innocent: After experiencing a head injury in "Ugly, Dirty and Good", he completely forgets his villainy and acts like an innocent Nice Guy. It doesn't last, though.
• Bad Boss: Post-Flanderization. Despite still being their leader (and caring about them deep down), Joey can get physical with Dee Dee and Marky. It's especially when they tick him off, which is easy to do. Downplayed in Oggy and the Cockroaches Next Generation as his abusive tendencies only show up a couple times.
• Bad Liar:
  • While attempting to disguise himself as Oggy in "Inside Out", Joey tries lying to Jack that he didn't know why he "suddenly" got antennas, seemingly saying that he grew from his... ears.^note Joey himself naturally has antennas but Oggy doesn't. Jack didn't seem to buy it.
  • In "Little Tom Oggy", Joey tries tricking Dee Dee into thinking that Marky was for fighting for his stuff. But, he was actually just as guilty as he was. Nevertheless, Dee Dee doesn't buy it because he saw him fighting with Marky.
• Beard of Evil: Overlaps with Animal Facial Hair; he's a callous, scheming villain who gets a beard in "Hide and Go Whiskers!".
• Berserk Button: Episodes like "House For Rent", "Going Up" and "A Jealous Guy" show that Joey hates it when Oggy outwits or defeats him.
• Bitch in Sheep's Clothing: Occasionally he pretends to be a Nice Guy, like when he tries acting decent towards a termite in "Termite-ator". However, his mask starts slipping when she starts defying him.
• Black-and-White Insanity: An implied case. One of his descriptions implies he thinks in black-and-white terms^note his Xilam profile states, "For Joey, things are black and white;...". The other part is only during his Villainous Breakdown in "Oggy's Double", though.
• Butt-Monkey: Joey tends to have it worse out of all the cockroaches.
• Cheery Pink: A male example in "Ugly, Dirty and Good" when he starts acting like a Cheerful Child after getting a head injury (and Amnesiacs are Innocent). He also has a pink body and a pink eye.
• Combat Pragmatist: His devious nature sometimes extends to combat. "Water Sports" for instance has him get in a Sword Fight-esque battle with Jack, which he wins via stabbing his raft.
• Did Not Get the Girl: Aside from his failed attempts to win Lady K's heart, there are two instances where he did get the girl, only to lose her by the episode's end:
  • "Honeymoon": Joey falls in love with a bee Oggy took in and, despite some setbacks, successfully courts her. However, the interference of the other cockroaches and the injuries inflicted on her (inadvertant or not) by the other residents of the house (and an accidental one by Joey himself) cause her to lose a good amount of her sanity and try to fly away from Oggy's house. Joey, in a surprisingly pitiable moment, tries to stop her and relentlessly begs for her to stay... and gets a stinger right through his head in response.◊
  • "V.I.P Party": He succeeds in wooing a beautiful guest of Lord Latouille's party with his charms, even beating another suitor into the hospital when he tries to seduce her. But while she enjoys his company very much, midnight strikes, and she has to go home. Though devastated, Joey nonetheless keeps (and kisses repeatedly) one of her high heels as a memento.
• Ditzy Genius: He's fairly clever, but isn't free from moments of tomfoolery.
• Dragon Rider: A villainous equivalent in "Oggy's Dragon" when he (forcibly) rides the titular dragon.
• Dreadful Musician: In later seasons, while Played for Laughs, Joey's singing voice is terrible.
• Early Installment Character-Design Difference: A downplayed one. His right eye is red in his earlier appearances, but pink elsewhere.
• Entitled Bastard: A subversion. While he often abuses Oggy and/or Jack, he flat-out begs them in "Fake News" for food with Puppy-Dog Eyes. But it's soon revealed he was just acting and it was part of his Evil Plan.
• Even Evil Has Standards: He may mess with pretty much everyone and everything for a cheap laugh, but "Emergency Room" shows that he does not necessarily want to harm the elderly. While joyriding Oggy's hospital bed, an old man starts crossing the hall ahead, resulting in Joey shouting and gesturing for him to get out of the way.
• Evil Plan: His specialty. He wants to become wealthy, for starters.
• Family Eye Resemblance: A downplayed example. Joey and his father from The Movie's "Prince Oggy" segment have similar (but not identical) eye colors.
• Flanderization: Yeah, Joey was always mean-spirited. But sometimes in later episodes, he physically harms his own friends (especially when they tick him off, which is pretty easy).
• "Flowers for Algernon" Syndrome: He once lost basically all of his negative traits and became a sweetheart... only to later revert back to his typical self.
• Four Is Death: He's sadistic and his body has four lines in the original series.
• Giftedly Bad: A Played for Laughs one. Joey seems to think he's a fine singer in later seasons... when his singing voice is actually horrendous.
• Greed: Joey's most noticeable trait is that he loves money.
• Hat of Authority: When leading his army (which is primarily composed of stickmen) in "The Magic Pen", he's also its only member who's wearing a hat.
• Height Angst: An implied Type I in "Joey and the Magic Bean". He, The Napoleon and the shortest member of the main cast, seems offended after Oggy mocks the cockroaches for being smaller than him. It's especially compared to Dee Dee and Marky, who are taller than Joey and didn't seem bothered by it.
• Hope Bringer: A rare villainous example. In "Roach Vision", Dee Dee and Marky (most notably the latter) had lost hope that they could beat Oggy because of his special glasses which help him defeat them. They even start trying to move out... until Joey comes along! He even has a new scheme which gives them hope! Doubles as Irony since they're all Hope Crushers themselves.
• I Just Want to Have Friends: He spends much "Oggy and the Grasshopper Cloud" trying (and failing) to befriend some grasshoppers as his friendships with Marky and Dee Dee both temporarily ended.
• It's All About Me: For starters, in "Deep Trouble", Joey wanted to hog a submarine's wheel. However, Marky and Dee Dee start messing with it. He then tries to order them to get off it, but when they don't listen, he just throws them off.
• Jerk with a Heart of Jerk: He's devious, greedy, selfish, and the cruelest of the trio. In later episodes, it sometimes gets to the point where Dee Dee and Marky will briefly get Oggy's help or defy him when he gets out of line. There's also several instances in which he seems to be showing a redeeming quality, but then shows that isn't the case (although he does have genuine, likable moments).
  • He initially seems disgusted in "Scaredy-Cat" when a swamp monster starts chasing Oggy. But, while possibly Played for Laughs, he then happily puts on 3D glasses and starts recording the ordeal.
  • In "Wheeling and Dealing" (which is set in prehistoric times), after unintentionally breaking Oggy's wheel, Joey initially seems sorry for him and bad about what he did. But, it's soon shown he was only upset because the wheel getting broken means he can't use it himself.
• Laughing Mad: Particularly during his Villainous Breakdown in "Oggy's Double"; he breaks down in high-pitched laughter as a sign he (temporarily) lost it.
• Manchild: After getting a head injury in "Ugly, Dirty and Good", he acts like a sweet Cheerful Child stuck in a grown-up's body. Not that this lasts.
• Manipulative Bastard: Occasionally, especially in "Fake News" when Joey pulls off a Wounded Gazelle Gambit and tricks basically everyone into thinking Oggy is a villain.
• Mister Big: He's the shortest of the cockroaches, their leader, and The Napoleon.
• Modest Royalty: In the movie's "Prince Oggy" segment. Nothing screams "I am a prince!" more than wearing: black gloves, a brown belt with a dark yellow belt buckle, and a black and dark green cape.
• The Napoleon: He's the shortest of the trio and has a short fuse.
• Odd Friendship: Despite being the biggest Jerkass of the trio, he tends to bond the most with Oggy. Big examples being in "Virtual Voyage", "Mission to Earth", "Ugly Dirty and Good" and "Journey to the Center of the Earth".
• Only Sane Man: Being more sensible than Dee Dee and Marky generally are, Joey occasionally acts like this when he's with them, like when he's Surrounded by Idiots (and seems to think so) towards the beginning of "Penalty Shot".
• Overlord Jr.: In the "Prince Oggy" segment, it's heavily implied he's as evil and sadistic as his deceased father was.
• Pet the Dog: Despite his self-serving personality, he does have his nicer moments.
  • Joey actually saves Oggy from falling to his death in "Journey to the Center of the Earth".
  • In "Inspector Dee Dee", Joey was willing to give back Oggy's flyswatter after briefly having it stolen by an octopus. He even fist bumps him after he squashes Marky with it.
• Pragmatic Villainy:
  • Sorta in "Happy Birthday". When Oggy is Carrying a Cake, Joey stops Dee Dee from flat-out stealing it... because he wanted to literally pull the rug from under the feline.
  • He helps Oggy lose weight in "Oggy's Diet" to get him to get off his diet. This is because, during it, he started filling his fridge (which Joey commonly gets food from) exclusively with sucky drinks.
  • In "Shoplifting!", Joey has no interest in robbing a grocery store; he knows that, unlike Oggy, it'll have multiple means to deal with thieves and he and his cohorts could actually go to prison. Unfortunately, Lady K convinces him and the others to do so anyway.
  • Joey quits trying to make Oggy stop playing music in "Oggy's Got Talent". Not because he likes it, mind you, but because he realized it'd make him a great cat's-paw to help him get rich.
• Rabble Rouser: You can thank him for inciting a duck mob in "Duck Soup". It's implied at the end of the episode that he incited a mob of chickens too.
• Reclining Reigner: He does a Slouch of Villainy in The Movie's second segment, in which he's a prince.
• Red Eyes, Take Warning: A downplayed case; in earlier episodes, Joey's right eye was red instead of pink. His left eye, however, is yellow.
• Red Right Hand: He's the only character, at least of the main cast, with mismatched eyes^note he has a yellow left eye, and his right eye is pink (originally red). He's one of the most malicious.
• Royals Who Actually Do Something: A villainous example in The Movie's second section, in which he's a prince who isn't above getting his hands dirty.
• Shorter Means Smarter: Along with generally being the trio's The Smart Guy, Joey is the shortest of the three.
• The Smart Guy: He's usually the smartest of the trio.
• The Tease: A Played for Laughs example in "Oggy's Special Spa", when he teases Oggy... suggestively.
• Tiny Tyrannical Girl: Gender-inverted. He's The Napoleon and heaven forbid you defy him.
• Too Important to Walk: Sometimes, especially in later episodes, he has the other cockroaches carry him.
• The Unfettered: A Type I. He doesn't care about what he has to do to get wealthy. If it involves hurting his friends, so be it.
• Vague Age: A subverted example. The series doesn't reveal his age... until "Let's Party, Guys!" when we get to see his ID and his birthdate is listed as June 15, 1991.
• Villain Has a Point: As mean as he is, Joey has his moments of this. In "Artsy Oggy" for instance, he accurately calls out Oggy on being a fraud.
• Villainous Princess: Gender-inverted in The Movie's second segment, in which he's a vicious prince.
• Villainous Rescue: In "Journey to the Center of the Earth", he actually saves Oggy from falling to his death, despite being an unruly and unpleasant bully.
• Yellow Eyes of Sneakiness: A downplayed one. Joey's left eye is yellow, denoting to his sneakiness, but his right eye is pink (originally red).

Marky

Marky

Marky is a suave, heartbreaking, grey-bodied, green-headed roach with pink eyes, often not really caring about what the two others are doing. His hobby is dating girls—even puppets—and reading books.

---

• All Animals Are Dogs: A justified example. Marky is a cockroach (which isn't a dog) but he spends much of "Oggy and the Magic Flute" acting like a Canine Companion to Oggy; he can tranverse on all fours, pant (complete with his tongue sticking out), etc. However, this was because his "flute" charmed him. Also, it's later revealed that anyone it charms acts like a dog.
• Canine Companion: He acts like one during much of "Oggy and the Magic Flute", in which he's friends with Oggy and plays All Animals Are Dogs straight.
• The Casanova: He was one in the early episodes but this trait has since disappeared. It seems to have returned in a season 5 episode.
• Comically Missing the Point: In "Ugly, Dirty and Good", in which Dee Dee tells him he has to whack Joey's head in order to make him come back to his senses, he constantly hits Dee Dee every time he asks to do it. Justified since the latter wasn't clear enough the second time he explained his plan.
• Cuteness Proximity: He finds a baby panda in "The Precious Panda" adorable. He also has this reaction (although it's comparatively downplayed) in "Fake News" upon seeing Oggy and Jack after they try making themselves look like Cute Kittens.
• Damsel out of Distress: Gender-swapped in "Sacrificial Special". After letting Bob capture him, Marky manages to escape and steal his treasure (the latter being why he got Captured on Purpose).
• Early Installment Character-Design Difference: A downplayed example. Originally, his eyes were red, but they were later changed to pink.
• Enraged by Idiocy: Zig-zagged, usually he doesn't mind Dee Dee goofing around, but in other occasions, such as episodes like "Marky Da Vinci" "Journey To The Moon", he will often reprimand him for his obliviance.
• Evil Cannot Stand Cuteness: Inverted. He's a villain who's experienced a couple Cuteness Proximities.
• The Generic Guy: Becomes this after season 1 due to his Casanova trait being phased out. Generally, most of the episodes are pretty evident on how he lacks an actual personality to stand out - compared to his friends. While he does have traits that are demonstrated for very few episodes (being a casanova as mentioned before, skilled at three things, and apparently able to develop obsessions with items that he really enjoys (or would enjoy) having^note in "Oggy and the Not So Smart Bracelet" and "Oggy's Teddy Bear", both being season 7 episodes, mostly, he serves to help his companions.
• Girls Love Stuffed Animals: A gender-swapped example; "Oggy's Teddy Bear" shows he loves Oggy's teddy bear.
• The Heart: It happens rarely, but if there's one who would try to break up fights between his fellow cockroaches, that's Marky.
• Hidden Depths: In some season 5 episodes, he's surprisingly really skilled at chess, art, and is great at building (but with sandstone).
• I Just Want to Be Loved: All he wanted in "Caviar on the House" was for Joey and Dee Dee (who he felt rejected by) to like him.

• Informed Attribute: Official profiles state he has two hobbies: reading books, which is rarely demonstrated, and dating puppets.
• Lean and Mean: Downplayed, usually he is seen with a pot belly, however he still remains fairly slender, especially if compared with Dee Dee and Joey. Parodied in "French Fries". Apparently, he is so skinny, he doesn't get hurt by Oggy's old flyswatter.
• O.O.C. Is Serious Business: One of the reasons Joey and Dee Dee got suspicious of Marky in "Caviar on the House"? He wasn't joining them in devouring Oggy's food with them like he usually does.
• Out of Focus: Downplayed, he has appeared in every single episode except for "The Pumpkin That Pretended to be a Ferrari", "Perpetual Motion", "Safari, So Good" and "Happy Campers"; but he rarely ever gets the main spotlight. There have been roughly six episodes that primarily focus on him.^note That being: "Baby Doll", "Jealousy", "Hip Hip Hip Hypnoses", "Mind the Giant", "Caviar on the House" and "Marky's Tournament".
• Shipper on Deck: Towards Oggy and Olivia, at least in "Oggy's 1001 Nights" when he's clearly happy after they're reunited.
• Red Eyes, Take Warning: He originally had red eyes instead of pink ones.

Dee Dee

Dee Dee

Dee Dee is an ever-hungry, devour-it-all, purple-bodied, orange-headed roach with green eyes. His appetite sometimes reaches ridiculous regions, often resulting in the consumption of larger animals or other things.

---

• Acrofatic: Although he isn't fat, but more on the pudgy side, he is the largest of the cockroaches, yet he is just as agile as the others and can outrun other characters easily.Even in the cancelled mobile game "Oggy Runner", in which he is the slowest of the cockroaches and therefore the easiest to catch, he is by far the best jumper in the game compared to his brothers and Oggy himself.
• "Aww"-choo: It's shown in the first episode of Oggy and the Cockroaches Next Generation that he sounds cute when he sneezes. Possibly invoked, however, as he did sneeze while he and the other roaches were "convincing" Oggy and Piya to get them back in the house.
• Big Eater: Basically the entire point of his character. It's no secret that his appetite is by far the most gargantuan out of all the cockroaches', and also the reason of why he is often involved in Joey's plans. Exaggerated in the ending of the episode "Termite-ator" in which he wolfs down almost every house in Oggy's neighborhood.
• The Big Guy: To his fellow cockroaches. He is definitely the toughest of the bunch and the one who usually performs the most complex task in the Cockroaches' evil deeds.
• Crouching Moron, Hidden Badass: "Inspector Dee Dee" shows how much of a Determinator he is when it comes to crime solving.
• Does Not Know His Own Strength: A justified example in "Oggy vs. Super Roach", in which Dee Dee unintentionally removes part of a steel pipe. However, this was soon after getting Super-Strength and beforehand he didn't know he received it.
• Dumbass Has a Point: He's not very bright, but sometimes (especially in later episodes), he does make valid points. In "Little Tom Oggy" for example, he points out to Oggy that trying to sleep in Pit's doghouse is an asinine idea, not that he listened.
• Extreme Omnivore: He has eaten fishes from a wallpaper in "Oggy's Clone", and to a lesser extent, managed to eat an entire hyena in "Safari so Good".
• Fat Bastard: Mean, yet not lean. Temporarily inverted in "Dee Dee's Diet" when he does become lean.
• Fat Idiot: Downplayed. He's the chubbiest and in some episodes, he is portrayed as the most gullible and clumsiest of the cockroaches, but he otherwise has instances where he can come up with plans and he is as just good as his brothers at outwitting the cats and giving them grief. Briefly inverted in "Dee Dee's Diet" when he's temporarily very skinny.
• Fat Slob: He's sloppy and overweight.
• Gender-Blender Name: Although the name "Dee Dee" is feminine, this Dee Dee is a male.
• Genius Ditz: Not an actual ditz per se, but, when they aren't basic and self-explanatory assumptions, his plans turn out to be more ingenious compared to Joey's. Special mention goes to "The Big Bad Wolf" when he came up with a clever contraption in order to save Joey.
• Master Actor: In "The Fugitive", he frames Oggy by pretending to be killed when he got caught red-handed by the cat. Justified, as he has already shown hints of his acting performance in "A Night At The Opera".
• Obsessed with Food: He's stated to be preoccupied with eating.
• Pint-Sized Powerhouse: It became a plot point in "Oggy vs. Super Roach", in which Dee Dee gains Super-Strength and was able to take out Oggy easily. Even in his normal state, he is seen carrying around objects, animals and furnitures with ease, something that a cockroach of his size wouldn't normally be able to lift.
• Real Men Hate Affection: He's disgusted when a hedgehog kisses him in "Saving Private Dee Dee". Granted, she was a random stranger.
• Singing Voice Dissonance: He's shown to have an astonishingly deep, baritone singing voice in "A Night at the Opera". This is Truth in Television, as most opera singers are often on the heavy side in order to make their voices sound deep and booming.
• Sinister Switchblade: He's a Fat Bastard who uses a switchblade in self-defense in "Trans-Amazonian".
• Sinister Whistling: A downplayed variant in "Masquerade" when he whistles before committing the absolutely heinous felony of trying to ruin Oggy's confetti.
• Smug Super: After gaining Super-Strength in "Oggy vs. Super Roach", Dee Dee gets very arrogant.
• Villainous Glutton: Dee Dee's appetite is even bigger than Joey and Marky's (who have big appetites themselves).

The Others

Olivia

Olivia

Oggy's other next-door neighbor, and love interest. She later became his wife in the season 4 finale.

---

• Accessory-Wearing Cartoon Animal: Olivia has only a yellow bow on top of her head.
• Beware the Nice Ones: Olivia has no ill will towards anyone, but if pushed far enough, she can get fed up with others and show she's not all smiles and cheers. Examples include clobbering Bob with a rake for making fun of her pimple in "Olivia's Pimple" and intimidating the cockroaches (particularly Joey) into helping her reverse a witch's curse on her neighbors^note  that they caused by accidentally ripping her hat into shreds and framing them for it in "Back To The Past!" with a spiked flyswatter.
• Demoted to Extra: In the original show, Olivia is one of the central characters. In Oggy and the Cockroaches Next Generation, however, she's not as crucial.
• Friend to All Living Things: Even to the cockroaches, who she'll hurt only when she thinks that they've gone too far.
• Innocent Blue Eyes: Perfect for someone who's friendly to everyone, even the roaches.
• Living with the Villain: Unknowingly lives with Lady K, of all characters, although she's absolutely nothing like her.
• Love Interest: To Oggy.
• Nice Girl: It's rare to find a character who's actually consistently nice, and that's where Olivia comes in. She'll even tolerate the roaches' presence, so long as they don't make her mad.
• Official Couple: She and the titular Oggy are confirmed to be a couple.
• Out-of-Character Moment: She has two, in "Oggy and the Not so Smart Bracelet". The nature-loving cat who's unaware of the roaches' mischievous actions suddenly retaliates at them with violence... for whatever reason. She squashes Marky with a pineapple after he attempted to steal her bracelet, and attempted to swat his friends after they wanted to show her something.
• Pantsless Males, Fully-Dressed Females: In Season 5, Olivia wears full clothes most of the episodes while the boys wear either pantsless or shirtless, Fully Dressed to Cockroaches' Pantsless Males.
• Pink Girl, Blue Boy: The Pink Girl to Oggy's Blue Boy.
• Plucky Girl: She's cheerful, optimistic, and quite determined.
• Relationship Upgrade: As said above, she and Oggy eventually get married.
• Tertiary Sexual Characteristics: You can tell she's female due to her pinkish and feminine colors, bow ties and long eyelashes.
• Token Good Teammate: Out of all characters, she is the nicest.

Bob

Bob

(growling noises)

Oggy's next-door neighbor, frequently caught in the crossfire when Oggy's antics get out of control.

---

• Angry Guard Dog: Resembles one. Funnily enough, he is an actual guard in a few episodes like "Shoplifting!" and "Fake News", and he's got the temper to match.
• Ascended Extra: In the first 3 seasons, Bob was nothing more than a recurring character. However, in season 4, he became one of the show's main characters.
• Butt-Monkey: While not as often as some of the other characters, he still tends to suffer sometimes. The best examples being in episodes like "The Piggy Bank" and "Don't Barge In!".
• Character Development: Due to becoming an Ascended Extra, his tendency to beat up Oggy and Jack from time to time is downplayed in season 4, and he occasionally has a good time with both of them. This is especially noticeable in the episode "Steamed Out", where he genuinely wanted to hang out with Oggy and Jack.
• Cranky Neighbor: Especially in the first few seasons. He hated Oggy and Jack, and usually used to beat them up if provoked.
• Expy: Bob is basically an angry version of Spike.
• Girls Love Stuffed Animals: A gender-flipped example; he adores stuffed animals as shown in "Oggy's Teddy Bear".
• Hair-Trigger Temper: Bob scarcely has patience for his neighbors' antics; if they anger him, he will get physical.
• Identical Stranger: The bodyguard seen in "From Mumbai with Love" looks exactly like Bob with a moustache. Possibly Subverted, as Bob has been seen with several different jobs in lots of different places so this bodyguard could actually be him.
• Jerk with a Heart of Gold: He's mean towards Oggy and Jack and can be quite a bruiser, but he can also be a pretty swell guy. For example, he civilly hangs out with Oggy and Jack a lot in Season 4 and "Oggy's Teddy Bear" shows that he collects stuffed animals to sleep with at night.
• New Job as the Plot Demands: From Season 3 onwards, it's not uncommon to find him working different jobs, such as a police camp trainer, the head deliveryman, the head garbage man, and even the bodyguard for a celebrity... in India.
• No-Holds-Barred Beatdown: Does this regularly to Oggy and/or Jack whenever they provoke him, accidentally or otherwise. When it comes to the cockroaches however, they are the one target he can beat up on without the viewer feeling sorry for them, given that they are sadistic, obnoxious pranksters with a knack for wreaking havoc.
• Pet the Dog: When Jack accidentally drives a motorcycle through his house and into him in "Control Freak", he simply brings him back to Oggy and tuts, as if telling them not to let it happen again. He leaves it at that, even though he is covered in a tire track, and he has beaten the two up for much more minor inconveniences in the past.
• Running Gag: His only role early on was to be inconvenienced whenever Oggy's antics spilled out of his own home, often pummeling Oggy to send him back to his house.
• Stout Strength: Despite his rotund build, he's shown to be strong enough to beat the everloving crud out of Oggy.
• Villainous Breakdown: While Played for Laughs, he begins crying rivers when Jack ruins both his ship and his Evil Plan in The Movie's "Oggy-Wan Kenoggy" segment.
• Wouldn't Hurt a Child: "Baby Boum" shows that, even if he finds himself stuck with a random, loud baby who painfully gropes his face, he won't dare take his anger out on it like he does to everyone else, and would rather leave the baby for Oggy to deal with.

Monica

Monica

(remastered version)

Oggy's twin sister.

---

• Furry Female Mane: Instead of ears, she seems to have blonde hair.
• Half-Identical Twins: Aside from their ears (though Monica looks like she has hair in place of ears) and eyes, Monica and Oggy look the same.
• Masculine Girl, Feminine Boy: The Masculine Girl to Oggy's Feminine Boy.
• Official Couple: Is confirmed to be in a relationship with Jack.
• Polar Opposite Twins: Oggy prefers to spend his days lounging about and eating. Monica prefers to rollerblade around and do sports; the more extreme, the better.
• Rollerblade Good: And she's had them since she was born!

Lady K

Lady K

A female cockroach living in Olivia's house.

---

• The Bad Guy Wins: In the episode, "Shoplifting!", she manages to manipulate the Cockroaches into helping her steal loads of food from the grocery store, while giving nothing to them in return. Made even worse when it's implied that she's going to trick the Cockroaches again into robbing a train.
• Creepy High-Pitched Voice: Lady K is a horrible woman with a high-pitched voice.
• Cute, but Cacophonic: She's pretty (especially to the cockroaches) and has a Creepy High-Pitched Voice.
• Distaff Counterpart: Lady K is basically the result if one took Joey, removed or toned down his redeeming qualities, dialed up some of negative traits, and made him female.
• Dude Magnet: Downplayed, but Joey's cousin and all three of the cockroaches are smitten with Lady K.
• Even Evil Can Be Loved: Despite how despicable Lady K is, the cockroaches (especially Joey) still love her.
• Evil Is Petty: She's even worse than the cockroaches in this regard; Lady K once tried to murder Olivia just because she unknowingly poured water on her.
• Evil Wears Black: Lady K isn't immune to wearing a red and black dress.
• Fanservice Pack: An inverted case; Lady K's Non-Mammal Mammaries get get removed in her later appearances.
• Femme Fatale: She's cunning, intelligent and much more evil than any other character in the show, and can even get Dee Dee, Marky and Joey to do whatever she wants...even to forgive her for eating all the food they stole.
• Girls Like Musicians: Apparently, she falls in love with Joey's cousin in "The Cucharcha" because he's a guitarist.
• Green and Mean: "Mean" is an understatement, but she's green-eyed and has worn a dress with some green.
• Humanoid Female Animal: She resembels a human more than the male cockroaches, with her hair, human-like skin tone and legs, and breasts.
• It's All About Me: Unless your name is Lady K (or you're the Mexican cockroach from "The Cucharcha"), she clearly just cares about herself.
• Jerkass: Saying she's a scumbag is a huge understatement. For starters, she betrays the cockroaches and had them get attacked by Bob the dog while she took the food they took for herself in "Shoplifting!".
• Karma Houdini: She hasn't suffered any comeuppance in the show.
• Lady in Red: Is a Femme Fatale who isn't above wearing a red and black dress.
• Laughing Mad: She started laughing maniacally when she plots a very Snow White situation by poisoning an apple...just because Olivia was watering her flowers and unknowingly drenched her.
• Makeup Is Evil: Lady K clearly wears make-up, and is clearly the series' most rotten character.
• More Deadly Than the Male: The cockroaches (all of which are male) are not saints themselves. But she's even worse than them.
• Non-Mammal Mammaries: Cockroaches in Real Life aren't mammals, not like this stops Lady K from having breasts.
• Red and Black and Evil All Over: A vicious Femme Fatale with a red and black dress.
• Villainous Glutton: The "Villainous" part is a given. As for the "Glutton" part, Lady K eats an enormous amount of food in "Shoplifting!" and was implied to still be hungry.

Pit

Pit

Obviously, this didn't end well on Deedee's end...

A dog who's very aggressive.

---

• Jerkass: Just like Bob but even more jerkish.
• Karma Houdini: He was never punished for his actions.

Piya

Piya

Debuting in Oggy and the Cockroaches: Next Generation, Piya is a seven-year-old elephant who Oggy has as a guest.

• Birds of a Feather: She and the roaches get along fairly well when they're not fighting. And it seems to be due to their childish, pleasure-seeking personalities.
• Cheerful Child: A bubbly seven-year-old girl.
• Cheery Pink: She's a pink and energetic girl.
• Genki Girl: Her abundance of energy coupled with her desire to play nearly all the time often leaves Oggy exhausted.
• Nice Girl: She's typically shown to be a sweetheart.
• Sympathy for the Devil: Despite them being a Terrible Trio, Piya sympathizes with the roaches several times, like when she pities them in her debut after Oggy kicks them out of his house.
• Tertiary Sexual Characteristics: Maybe she would be a Lady Looks Like a Dude... if it weren't for her noticeable eyelashes and pink coloring.
• Younger than She Looks: At least when compared to other kid characters, she looks sorta like a grown-up, mainly due to her being larger than several adult characters (e.g. Jack). Despite this, she's confirmed to be seven years old.
