As depicted in the opening sequence of each episode, the Powerpuff Girls were created by Professor Utonium in an attempt to create the "perfect little girl" using a mixture of sugar, spice, and everything nice. However, he accidentally spilled Chemical X into the mixture, granting the girls their superpowers.
All of the Other Reindeer: At first in the movie. Also, in "Town And Out" when they move into Citiesville, until they decide to move back to Townsville.
Artificial Humans: Created in lab. Also leads to an in-universe case of the Uncanny Valley, since the girls' eyes, hands (or lack thereof), and proportions are often mentioned as being creepy and strange to the people they meet. The reporter in The Movie actually calls them "little bug-eyed freaks".
Cain and Abel: The Abel to Mojo Jojo's Cain. They are also the Abel to the Rowdyruff Boys' Cain, though they're technically created directly and indirectly, respectively.
Powerpuff Girl Hands: The Trope Namer. Lampshaded when they accidentally switch bodies with the Professor, Mayor, and Miss Bellum: Buttercup (as the Professor) attempts to pick up the hotline by basically karate-chopping the air next to it, complaining that "your hand doesn't work!" when this accomplishes nothing.
Theme Naming: All 3 girls (plus Bullet and Bunny) have names that start with a B and have double consonant. Notably Princess' name starts with a P and her double consonant is at the end instead of the middle of her name, she's the only Powerpuff esque character never to be acknowledged as part of the team or kept Chemical X powers.
Blossom is the redhead in the pink outfit and signature red bow. She's the "smart one" and the self-proclaimed leader of the group, although at times she can be bossy or over-analytical. Her unique ability, introduced in the episode "Ice Sore", is ice breath.
Bubbles: [eagerly] Ooh, ooh, I want the blond! I think he's cute!
Buttercup: Man, you're weird!
It helps that her shot still for when she kisses Boomer has her basically hug him towards her while looking happy in comparison to her sisters' distance (they avoid all contact with the exception of the lips to their cheeks) and distaste.
Buttercup has the green outfit and black hair. She's a tomboy, and the "toughest fighter". She's the most aggressive and confrontational sister, and has gained a reputation among the bad guys of Townsville as the most vicious of the trio. Unlike her sisters, she doesn't have a unique ability (to her chagrin); however, it's eventually revealed in the Season 6 episode "Nuthin' Special" that she's the only member of the team who can curl her tongue. Well, at least it's something.
Forgot I Could Fly: In "Down D Dirty", she is being chased by a mob of townsfolks for refusing to take a bath, when she abruptly stops and asks, "Wait, what am I doing?" before taking off into the air.
Heartbroken Badass: After she realises Ace was lying to her in "Buttercrush". She gets over it pretty quickly, though.
Hidden Depths: Although she rushes headfirst into situations and prefers to solve things with violence, she is smarter then she is given credit for and often gives others an Eureka Moment, like in the movie.
Also in "Makes Zen To Me", when she goes to a temple to learn how to control her anger, she finds she actually likes doing things like lighting candles and meditating.
Ungrateful Bastard: Happened in one episode. In the episode "Down and Dirty," when she finally decides to take a bath. Instead of thanking Blossom and Bubbles, she just retorts on how she only took the bath so she could resume crime-fighting.
Blossom: You know Buttercup. You may be clean, but your attitude still stinks.
Professor Utonium is the brilliant scientist who created the girls in his lab. He acts as a father figure, caring for them as a single parent would. He's enthusiastic about his work, and cooks up all sorts of inventions and experiments in his lab.
Good Father: He's a loving, doting father for the girls.
Overprotective Dad: Every once in a while, it really hits the Professor that his three daughters are out laying their lives on the line to fight crime. His attempts to assist them, like in "Powerprof" and "Uh Oh Dynamo", usually end up not so good.
Crouching Moron, Hidden Badass: Despite being portrayed as incompetent and immature, the Mayor has shown to have the potential of being one of the most badass mayors in existence:
In the episode "Him Diddle Riddle", the Mayor successfully decodes Him's riddle "Where is boiling and freezing at the same time?" as coordinates in a matter of seconds through rapid explaination to the trio of dumbstruck girls, along with a more simple alternative.
Mayor: "... Or it could be there's an ice cream truck on fire somewhere. Have a nice day, girls!"
Also in the episode "Impeach Fuzz", Villain of the Week Fuzzy Lumpkins becomes the new mayor. The Mayor doesn't really care about this until he learns Fuzzy is wearing his hat and accepts a challenge to wrestle him for the hat and his title as mayor again. He's easily tossed around by Fuzzy and his kin until during a pin, Fuzzy mockingly puts the Mayor's hat on in front of him. Suddenly, the tables were turned in a matter of a second.
Mayor: "FUZZY! No one wears my hat!" [Suddenly rips his vest off, becoming RIPPED]
Well-Intentioned Extremist: In one episode, he tries to fight crime without the girls by using a hot air balloon with a boxing glove, but he ends up injuring innocent people, so the girls have to stop him.
You Don't Look Like You: The Mayor was drastically different in "Meat Fuzzy Lumpkins" and was voiced by Jim Cummings. But that could be a different mayor.
Voiced by Jennifer Martin
Ms. Bellum is the mayor's much-more-competent personal assistant, helping him out with whatever he can't handle on his own (i.e. just about everything). She's tall and has long, bushy red hair, but her face has never been shown—it's always blocked by the top of the frame, a conveniently-placed obstacle, or something like that.
Action Girl: She is one of the most accomplished martial artist in the series, capable of go toe to toe with Sedusa.
Badass Normal: She managed to defeat supervillainess Sedusa in a fight.
The Faceless: Until the 10th anniversary special, you have to look very carefully.
Impossible Hourglass Figure: She has large breasts, wide hips, and a waist about as thin as her neck. A number of characters have commented on her beauty.
MeaningfulPunny Name: Cerebellum, a region of the brain that plays an important part in motor control. In comparison to the Mayor, she seems more like the person who would be more fit to run Townsville.
Undying Loyalty: If all her interactions with the Mayor were not enough clues, during the Bad Future episode, an old Ms. Bellum is shown holding the Mayor hat years after he passed away, and when the girls try to come close, she snarls like a cornered animal and screams that the mayor is "hers and hers alone".
As one can readily deduce, Talking Dog is a canine resident of Townsville who has the inexplicable ability to speak English.
Butt Monkey: Gets his share of bad luck. He's constantly abused in almost every episode he appears in.
Kick the Dog: It is his role to be kicked to show how evil the villain is.
The series' enthusiastic narrator is never seen at any point in the series, though he is a person and not just a disembodied voice—for example, in "Monkey See, Doggie Do", he's turned into a dog along with the rest of Townsville, and in "Simian Says", Mojo Jojo kidnaps him and takes his place as the narrator. As the narrator, he, of course, has the ability to break the fourth wall.
The Other Darrin: In the "What a Cartoon" shorts, the narrator was voiced by the late Ernie Anderson.
The kindergarten teacher of Pokey Oaks Kindergarten. She is patient, understanding and very protective of her students, making her a well-liked, motherly figure.
Innocent Blue Eyes: Her eyes represent her kind personality and her motherly relationship with her students.
The Other Darrin: In the pilot, Miss Keane (who was then unnamed) was voiced by Kath Soucie.
Out-of-Character Moment: In the episode "Ice Sore," she forced her students to go outside in the hot weather, with no concern for their health. This is very jarring as she's usually very caring for her students.
Sickeningly Sweethearts: Her and the Professor in "Keen on Keane." However, this ends when the Professor can't stand her cat Valentino, causing the two of them to break up.
A Mad Scientist chimp with great intelligence, notable for his pseudo-Japanese accent and his convoluted, repetitive manner of speaking (inspired by the speech patterns of characters in the English dub of Speed Racer). As revealed in the episode "Mr. Mojo's Rising", and expanded upon in The Powerpuff Girls Movie, Mojo Jojo was Professor Utonium's reckless lab assistant, Jojo, before Professor Utonium created the Powerpuff Girls, and it was he who caused the Professor to accidentally add Chemical X to the mixture, thus making him responsible for their creation. The reason he hates the girls so much is out of jealousy of the affection they received from the Professor that he did not, though he never deserved it due to his destructive nature. According to a countdown of the 10 worst villains in the series held by Cartoon Network, he's the number 1 worst villain in the series.
Ax-Crazy: Often shows various features of mental instability, especially when he's pissed.
Department of Redundancy Department: He speaks this way all the time, which is to say that the manner in which he vocally expresses himself is extremely roundabout and repetitive, containing long and elaborate sentences which tend to reiterate their own subjects constantly. This is taken to extreme levels in "Mo' Linguish", where he's forced to teach a beginner's English class at Townsville Community College and ends up re-teaching the entire city to speak this way, which brings the entire city to a complete standstill.
Flanderization: An interesting case. In the film, he was probably one of the biggest threats of the series, however, the first seasons prove otherwise, he was just a Harmless Villain. Although it was not until the seasons 4 and 5 in which seem to show that he still remains an effective villain, as in the case of kidnapping and attempted murder in many cases to Professor Utonium.
From Nobody to Nightmare: He was originally just Professor Utonium's lab assistant, constantly wrecking and destroying the lab, but after starting the accident which made the Powerpuff Girls, he got an incredibly high IQ, had the girls create his lab through trickery, and has since established himself as the Arch-Enemy of the girls.
Genius Bruiser: Mojo is capable of building complex machinery in mere days. He also once defeated an alien invasion singlehandedly using only his gloved hands and a stale loaf of bread.
Luke, You Are My Father: Professor Utonium pointed out to Mojo, had he not pushed him as he was mixing the batch to create the perfect little girl, the Powerpuff Girls would never have been created. Meaning that Mojo Jojo is, on a strange technicality, the father of the girls.
Manipulative Bastard: Tricks a group of kids who idolized the Powerpuff Girls into allowing him to grant them powers. Turned out the Chemical X was spiked with something that made them go Drunk with Power and do anything to get more, including destroying the Powerpuff Girls.
Nice Job Fixing It, Villain: He helped set off the Freak Lab Accident that created the girls ("It was me...it was me..."), gave them their drive to fight crime, and his attempt to go back in time and kill the Professor inspired him to try and create them in the first place. Mojo just can't win.
Not So Different: "None of them will ever understand you as I can, for we are kindred spirits whose powers spring from the same source!"
One-Winged Angel: At the climax of the movie, he infuses himself with a massive amount of Chemical X, mutating himself into a gigantic monster with enough power to nearly defeat the girls. Undone when he's exposed to the antidote.
Sadist: He had no qualms when tried to kill the profesor with several weapons, and while he shooted him, he makes an insane Evil Laugh.
Start of Darkness: While having the destructiveness of a villain, Mojo was otherwise an ordinary chimp and not a true villain until the Chemical X explosion. After that, he would become a villain proper.
Tragic Villain: Mojo tries to lead the girls and the Professor to think he is this. According to his story, Mojo was the Professor's loving lab assistant who turned to evil after he was abandoned in favor of the new Powerpuff girls. In actuality, he was a destructive lab assistant that the Professor was forced to throw out when the girls were born.
Villainous Crossdresser: In "Slumbering With the Enemy", he attends the girls' slumber party as a girl. The Powerpuff Girls, naturally, treated the situation with hostility towards him, but once they see that he isn't doing bad things to anyone, it becomes Go-Karting with Bowser. Once eveyone goes to sleep, however, Mojo sets on his real mission: to get the Antidote X.
A mysterious, supernatural, red-skinned, effeminate (apparently androgynous) and immortal caricature of Satan. He is the ultimate embodiment of pure evil, and talks in a chilling voice that echoes at all times as if in a cave; the voice itself can vary from a high pitched falsetto voice, to a deep, booming, demonic voice. He is also the Girl's most dangerous foe as well as the hardest villain to defeat. He's one of the girl's main enemies, but in particular an enemy for Bubbles.
Beware the Silly Ones: Despite all his comical attributes, he's the girls most dangerous and vile enemy who consistantly comes close to victory with his plans. And then there's the Bad Future we see were he won...
Evil Is Petty: Him could win at any given time, but simply seeks to inconvenience the girls.
Evil Sounds Deep: Sometimes. His voice fluctuates between a girlish falsetto and a deep, reverberating growl, making him all the more unsettling.
Invisible Means Undodgeable: The Girls go toe to toe with him whenever he uses projectiles and beams. However, the moment he changes to his invisible Thought-Controlled Power, they're helpless.
Karma Houdini: The girls just defeated him twice and are often unsure how to fight him. There are some episodes where if it gets its way, as in "Speed Demon" and when their plans fail, mostly he is not punished.
Natural Weapon: His pincers. He also can apparently breathe fire, as seen in "Telephonies."
Not Me This Time: In one episode, the Gangreen Gang makes crank calls to the Powerpuff Girls impersonating the Mayor, telling them that various villains are doing evil deeds. One of those villains is Him, and when the Powerpuff Girls ask him if he was doing anything evil today, he says not today, because today he needs to Jazz-ercise and get in shape.
One-Winged Angel: In a Bad Future were he conquered Townsville (at least we hope it was just Townsville), he eventually turns into a giant demonic monster. He also performs this in "Power Noia" were he turns into an insect-like monster embodying the Girl's fears.
Punch Clock Villain: When he isn't the enemy of the episode, he's surprisingly polite and even owns a diner with delicious, if a bit overpriced, flapjacks. Main example: in "Telephonies," the girls broke into his house as he was jazzercising and he chatted rather affably to them.
Sadist: He enjoys torturing his victims psychologically.
The Scottish Trope: In His introductory episode, the Narrator states that "Him" is the only designation that is safe to describe Him with. According to Tom Kane, saying his real name causes you to explode.
Or if you apply some Fridge Logic, the reason the girls won't say his name (and part of the reason for his character costume) is that the girls (being 3 years old) can't spell... and have mixed upSanta and Satan
What an Idiot: In-Universe. In a demonstration of how evil he is, Him knocked the Earth out of its orbit, heading straight for the sun. Mojo Jojo went on a rant about how stupid that was, since Him will be destroyed along with everyone else. This gets subverted during the actual rant, as Him, not taking his eyes off Mojo, raises his hand in a stopping motion towards the sun, and it moves away. Or, the Earth moved back, it's all a matter of perspective.
A large, husky, furry pink bear-like hillbilly monster with a wide jaw, a green nose, two antennae on his head, bib blue overalls and brown countryman shoes. He talks with a Southern accent, and will shoot anything he finds trespassing on his property and is otherwise harmless. He lives in the woods next to the city of Townsville. He is also prone to destructive fits of rage during in which these times, gaining enough physical strength to overpower (and sometimes intimidate) the girls, to which they must outsmart him to beat him.
Took a Level in Dumbass: In the pilot, Fuzzy was smart enough to make a gun that turned things into meat, plus he had an overall calm demenor. In the rest of the show he's an anti-social hick who goes ballistic when you touch his stuff and can't invent a glass of water to save his life.
A gang of teenaged hoodlums that are green-skinned and unhealthy looking (as if suffering from gangrene). They do not have powers, nor are they truly a threat in many ways.
Ambiguously Human: It's never specified if they're humanoid monsters or weird-looking teenage boys. Although in one episode that opens with Professor Utonium rattling off the nature of the PPG's foes (before realizing that he doesn't know anything about Fuzzy Lumpkins) he mentions that they have a skin condition.
The Charmer: Ace can be very charismatic when he wants to be.
Faux Affably Evil: In a few episodes, such as the one where they try to make Buttercup one of them and when they get sent to school. They behave like perfectly polite angels, particularly Ace. It is, of course, all an act.
Manipulative Bastard: Ace was this to Buttercup after he found about her crush on him, and he used her infatuation against her to destroy her sisters.
Mistreatment-Induced Betrayal: In "Aspirations", when they team up with Sedusa, who makes them much more formidable in exchange for some artifacts that'll help regain her lost hair after it was cut off in her last encounter with the PPGs. However, once they bring her the artifacts and she becomes all powerfull, she kicks them to the curb. They tell the struggling Powerpuffs how to de-power her and even get the last insult in by knocking Sedusa into a mud puddle when she comes begging for their help.
Mr. Fanservice: Ace gets a lot of fan girls. The episode where Buttercup is infatuated with him probably helped.
The Unintelligible: Grubber...ppphhhttthhh! In "School House Rocked", however, he did show the ability to physically re-form himself and said "Hello, I'm Grubber, very nice to meet you all" before turning back into his normal self, if only for a few seconds.
A spoiled rich girl in the Powerpuff Girls' kindergarten class, whose partially unseen and mostly mute "Daddy" allows her to finance various evil plots to destroy the girls. Her hatred of them stems from her deluded rebuffed attempt to become one of them.
Early-Bird Cameo: Princess appears in the opening credits for a brief second, though does not appear until the Season 2 premier episode, "Stuck Up, Up, and Away".
Entitled Bitch: Princess felt that because she is rich and that she always gets what she wants, that the girls should immediately allow her to become a Powerpuff Girl. You can guess how she reacts when the girls tell her "no."
Evil Counterpart: If you take Buttercup, remove all of her redeeming qualities, add a lot of "spoiled brat" and "jerkass," then you have Princess.
She's one to Blossom too; Evil Redhead to Blossom's Fiery Redhead, has a bossy and demanding personality and is rather vain, much like Blossom can be, but has none of Blossom's compassion or competence as a leader.
Green-Eyed Monster: And it's her entire motivation for being an antagonist to the girls: she's jealous of their superpowers.
If I Can't Have You: She pretty much outright says it in her first appearance when she buys a powersuit and shrieks, "If I can't be a Powerpuff Girl, then THERE WON'T BE ANY POWERPUFF GIRLS!!"
Kick the Dog: In "Stuck Up Up and Away," she brags to Blossom about defeating her sisters.
She also gives a long insulting tirade to someone over the phone in one episode...then hangs up and reveals that the one she was talking to was her own mother.
Meaningful Name: Her name is Princess. Averted with her personality, though.
Missing Mom: Her mother is never seen in the show. She is only mentioned when Princess is on the phone and she says "My mom is such a pain in the butt."
Never My Fault : Princess ended up causing two bank robbers to get away in her attempt to be a Powerpuff Girl and when Blossom explained to her that they won't let her be one is for her own protection she goes to her dad blaming the Powerpuff Girls for what happened saying she was being perfect that saying it was her father's fault. The next day she comes in with a supersuit and calls the Powerpuff Girls out on turning the class against her even though everyone hated her before she even met the Powerpuff Girls. And this was just in her first appearance alone.
The Sociopath: Cares only for herself, with a disturbing Lack of Empathy for anyone else. For that matter, her father likely qualifies too, as he shows no care whatsoever for his daughter outside of just casually giving her whatever she wants.
A master (or rather, mistress) of disguise who uses her cunning and her sex appeal to trick powerful men into doing her bidding. True to her Punny Name, she has Prehensile Hair, which is her greatest asset in combat.
Attack of the 50-Foot Whatever: When the Gangrene Gang bring her three ancient artifacts, she grows into a huge giant that regains her lost hair (which are literally snakes, properly fitting her name) and more then a match for the girls.
Bald of Evil: Her third appearance is this as she still hadn't recovered her hair after Ms. Bellum and the PPG cut it off.
Batter Up: Says this when she hits the Powerpuff Girls with her scepter when she grows into a giant.
Bitch in Sheep's Clothing: In particular episodes like "Mommy Fearest," when she disguises herself as another woman with another personality (usually nice).
Stripperiffic: Femme Fatale dismisses her contemptuously as "That chick in the underwear."
The Amoeba Boys
Voiced by Chuck McCann
The Amoeba Boys are a trio of human-sized anthropomorphic protozoan gangsters. They'd like to be the greatest criminals Townsville has ever seen, but their brains aren't developed enough to come up with any schemes more evil than petty shoplifting or littering. The Powerpuff Girls consider them harmless, to their dismay—they'd consider it a badge of honor if they were evil enough to get beaten up by the Girls. Ironically, they've come closer to destroying Townsville and defeating the Powerpuff Girls than most of the other villains combined—all by accident, of course.
Early-Installment Weirdness: In the original "Whoopass Girls" short, these guys were actually a threat, since their amorphous bodies could just absorb the girls' punches. The girls has to use the sun to deal with them.
Harmless Villain: The girls greet most villains with a melodramatic gasp; the Amoeba boys are more likely to get an "Oh... you," or (if it's been a long day) exasperated groans.
Mundane Made Awesome: The dramatic way they toss a piece of paper onto the ground in an attempt to commit a crime.
Poke the Poodle: The most evil thing they could think of to do was to stand on the grass in front of a "Keep Off Grass" sign.
Not-So-Harmless Villain: Unintentionally, but when they get sick, they accidentally infect the entire town and almost bring the girls to their knees.
Voiced by Rob Paulsen (Brick/Boomer), Roger L. Jackson (Butch)
A team of male counterparts of the Powerpuff Girls, created by Mojo Jojo out of snips, snails, and puppydog tails. They love causing mayhem, mischief, and chaos. They were originally one-off villains, killed off in the same episode they were introduced, but they were a fan favorite and were later resurrected by Him to become recurring members of the Rogues Gallery.
Badass: They have defeated the Girls by raw power and strength alone. The Girls themselves have to reach inane strategies to be able to defeat them (give them kisses, or threaten their masculinity).
Big Brother Bully: In a sense. Much like Bubbles is seen as the "youngest", Boomer more than likely fits it too, and gets picked on by Brick and Butch.
Big Brother Instinct: Regardless of their treatment of Boomer, Brick and Butch actually searched for him once they find out he's missing in a representation of concern. And all three tend to come to one another's aid (if needed).
Characterization Marches On: They were rather one-note when they were first introduced, but more mentally competent. Their reappearance has them dumbed down in intelligence in exchange for having their own distinct personalities.
Character Tic: Butch often twitches, like he's had too much caffeine.
Counterpart Combat Coordination: The battles between them and the Powerpuff Girls, though there's the rare switch around (they definitely did so in the Rowdyruffs' debut episode).
Cute Bruisers: Although they will punch your lights out if you call them "cute".
Dumb Blonde: Boomer. His brothers aren't that much better really, but Boomer simply says idiotic things that make no sense and he's, well, blond.
Funny Background Event: When they re-appear in "The Boys are Back In Town", the girls make fun of their "scary new hairdos", Brick is angry that they aren't scared, Butch is still grinning manically and Boomer...fluffs his hair appreciatively.
Ship Tease: Surprisingly, between Boomer and Bubbles, though one-sided on her part. It's not much, but she does exclaim that she wants the blond because he's "cute" very excitedly and is all too willing when kissing him on the cheek (she embraces him while doing so).
Something Else Also Rises: After they're brought back, the girl's kisses no longer defeat them, they make them grow larger. And when their masculinity is threatened they shrink.
Theme Twin Naming: Just like their female counterparts all their names start with the letter B (Brick, Boomer and Butch).
Trio Of Mass Destruction: Every time they appear for a fight and in general. They are even a serious threat to the Powerpuff Girls, who are also capable of mass destruction. As one can understand, pitting them against each other is not the best result for Townsville.
Voiced by Jess Harnell
A one-shot villain who appeared in the musical "See Me, Feel Me, Gnomey". One of the few antagonists in the series that has died.
Badass: And HOW. He is the most powerful character in the whole series by far. He probably has a power to that of a god.
When communicating with their ancestors, he sings a rock song and then kills all the villains and evil people —including Him— without anyone's help and with his powers. Pretty badass.
Killed Off for Real: Ultimately he is killed by falling to his death, but actualy, his dialogue beforehand indicates that this is only because he willed it so himself, making it a suicide.
Gnome: Therefore, I conclude that I cannot exist in my...Utopian...mind!
Knight of Cerebus: Unlike all the other characters, he is the only one who mercilessly killed all the villains of the series and was successful to manipulate the girls, something no other villain has.
Would Hit a Girl: Kill a girl, actually. He killed all the villains on the show, including the female villains.
A one-shot villain in the show, appearing only in the Season 4 episode "Knock it Off", he used to be Professor Utonium's college roommate. He discovers the formula for creating the Powerpuff Girls and abuses it to mass-produce Shoddy Knockoff Product versions of them on an assembly line. Despite being only a one shot villain, he manages to be one of the most evil and memorable characters on the show.
Bad Boss: Presumably, as he is seen constantly yelling at his workers to work faster and doesn´t appear to care about them looking overworked. To say nothing of his treatment towards the Powerpuff Girls Xtreme...
Embarrassing First Name: Although since he introduces himself as "Dick Hardly", apparently he doesn't find his first name embarrassing.
Establishing Character Moment: In flashbacks, his lecherous and greedy tendencies were made all too apparent. Made even more apparent when he looks through the professor's mail and calls him a geek (albeit not in front of his face), almost as if they just wanted to make sure you know he's still not a nice guy.
Evil Counterpart: To Professor Utonium, in that he's a man of science (though with slightly less "science"), but has none of the compassion and legitimate love the Professor has for the girls.
From Nobody to Nightmare: He was originally just a sleazy jerk who took advantage of Professor Utonium, but by the end of the episode, he's more or less a literal monster.
Hate Sink: Dick Hardly is one of the most despised cartoon villains.
Hoist by His Own Petard: When the replicas saw the Professor's love for the real girls, they questioned why they weren't loved to Dick. He told them to back off. Simply put, it didn't end well for Dick.
Jerkass: Even before he came up with his con, he was still a douche only putting on the nice facade when in front of the Professor.
"Whew! I thought I was going to turn into a horrifying monster there for a min-"
Shadow Archetype: To Professor Untonium. While the Professor loves and treasures his three creations, Dick regards the Powerpuff Girls Xtreme as expendable and only good for making money, even ordering his workers to melt down one of the clones for its Chemical X when he sees that she turned out to be a perfect copy of Buttercup.
The third notable female villain in the series, next to Princess Morbucks and Sedusa, despite being a minor villain. She only appears in the episode "Equal Fights" as a man-bashing Straw Feminist who only stole coins with Susan B. Anthony's portrait on them.
Also, she steals only Susan B. Anthony coins because she sees Susan B. Anthony, who struggled for the right to vote, as a symbol of women's rights, and she is...but as the Girls point out, Susan B. Anthony was willing to risk being imprisoned for breaking the law for what she believed in, while Femme Fatale uses her womanhood as a shield to get away with hurting people. Femme Fatale steals Susan B. Anthony coins, but she doesn't even know who she was.
Appears only in the episode "Boogie Frights." He hatches a plan to blanket the world in perpetual night by blocking out the sun with a giant disco ball, so that he and his fellow night-terrors can wreak havoc forever.
Ace Pilot: He pilots a space-ship to confront the girls when they attempt to shoot down his disco ball.
Punny Name: He's the lead bogeyman, and he and his cohorts utilize a disco theme.
Narrator: Uh-oh, looks like evil runs in the family.
Appear only in the episodes "Supper Villain" and "Just Desserts." The Smiths were an average family living next door to the Powerpuff Girls. Harold Smith had become sickened by his routine life and menial job at a mustard factory. Inspired by Mojo Jojo, he began to embrace the life of a supervillain. Unfortunately, he chose to do this on the night his wife Mary Anne invited Professor Utonium and the PPGs to dinner. Everything eventually devolved into a food fight, and the police arrest Harold. Mary Anne, however, put a lot of effort into the dinner, and upon seeing it get ruined, she vowed to destroy the Powerpuff Girls.
Berserk Button: Do not ruin Mary Anne's dinner. It's eventually not just pressed, but stabbed in about 100 times.
Evil Is Petty: Pretty much. Harold only became a villain out of spite to how "perfect" the Utoniums were while he was stuck in a rut where nothing exciting seemed to happen. Mary Anne turned just due to the fact the Powerpuff ruined her dinner (which technically was Harold's fault, he was the one who started the conflict in the first place). Julie (their daughter) was mad over PPGs losing her jumping jacks and Bud...well Bud's just an emo teen so he didn't take much convincing. This was eventually lampshaded when Blossom asked why they're attacking them:
Blosson: (After hearing Mary Anne's reason) That's not a good reason at all!
Jerk with a Heart of Gold: Despite his brattiness, he can also be seen getting along with the girls and the other kids at Pokey Oaks a lot of the time. He even managed to get on Santa's Nice list, much to Princess' surprise.
Jerk with a Heart of Jerk: In the Twiggy episode, where every time he appears to show some sort of nice side he winds up acting like even more of a brat than before.
Fake Ultimate Hero: He is able to solve every problem that pops up before the PPG can, because he sets up all the problems in advance!
Kick the Dog: His true colors are exposed when he literally does this to a dog (so he can then "save" the dog from a possible accident).
Suck Sessor: He becomes this to the girls; at first Townsville replaces the girls with this guy, but then the girls expose him as a fraud who's only good at being a superhero when he sets up problems to solve in advance.
Berserk Button: Anything resembling the little girl that ruined his career.
Disproportionate Retribution: "You laughed at me, but now, Revenge!" (Although technically his revenge is for the fact that them laughing at him indirectly caused his death, but since that was partially his own fault it's still this trope).
