Olivia "Liv" Rooney
Portrayed by Dove CameronLiv is the oldest kid of the four in the family, being the older one of the twins. She is a peppy, girly girl. Used to star in Sing It Loud, she is trying to adapt to a normal life.
- Ambiguously Bi: Gets really close with Fang when she comes to help Liv with a role. They even lick each other's faces.
- Attention Whore: Downplayed, Liv doesn't mind others having their moments in the spotlight, she just really loves fame and attention.
- Chekhov's Skill: That time she spent using power tools with Andie? It becomes really important later on in "Roll Model-A-Rooney" to prove that girls can be into things boys are into.
- Cool Big Sis: Liv tries her best to do so to Parker in "Sleep-A-Rooney" but has trouble being one (due to her being away from him since he was 6) and later succeeds.
- Cool-Kid-and-Loser Friendship: The cool to Joey's loser, while Maddie is somewhere in between.
- Ditzy Genius: Despite being bubbly, perky and fashion-obsessed, Liv is also very smart as revealed in the episode "Brain-A-Rooney".
- Dumb Blonde: While Liv played one on television, Liv herself admits she's neither this nor an Einstein.
- The Fashionista: Maddie even directly called her that. Liv seems to get it from her mother.
- Former Child Star: More like semi-retired, as she's trying to get a role in a movie while living at home. She completely retired her acting career in Season 2 in favor of a singing career. However, her acting career only grows from there, and no matter what, Hollywood will never leave Liv.
- Genki Girl: Liv has an outgoing personality and she's usually very enthusiastic and talkative.
- Girly Girl: Fashion obsessed and boys crazy, she's girly and proud, in contrast to her sister
- Hair of Gold, Heart of Gold: She is sweet, graceful, and often sees the good in everyone.
- It's All About Me: Sometimes. "Would it make you feel better about your injury if you heard about my horrible day?"
- Rousing Speech: Liv delivers one online in Rate-A-Rooney, and follows it with Music for Courage.
- Savvy Guy, Energetic Girl: She's a bubbly Genki Girl while Holden is calm and more relaxed.
- She's Got Legs: Maddie too, obviously, but Liv is more prone to showing them off.
- Shipper on Deck: For Maddie and Diggie.
- Smarter Than You Look: As seen in Ditzy Genius above, the episode "Brain-A-Rooney" shows that although Liv is no doctor, she is different from the Brainless Beauty character she plays on TV and is much smarter than people think she is, by helping Joey and Artie win the brain olympics. She even planed a complex birthday scheme for Maddie.
- Tomboy and Girly Girl: The Girly Girl to Maddie. Last to her bandmates Andie and Willow.
- Vocal Evolution: Her voice tends to get high-pitched from mid Season 1 onward.
- Wrong Genre Savvy: Often in the early episodes, Liv (being an actress herself) would treat high school problems as if they could easily be solved using ideas from her TV shows and movies. Naturally, they often backfire with Liv not understanding that real teens don't act the same way as on TV.
- Yank the Dog's Chain:
- Ever since Holden came back in her life, she developed feelings for him, but she gets prevented from having a relationship with him at every turn, or something unfortunate happens. In Prom-A-Rooney, Andie went to prom with Holden and started a relationship with him. In Triangle-A-Rooney, Holden broke up with Andie on television and confessed his feelings for Liv. It seemed Holden was within reach, only for Liv to realize she can't date Holden because due to circumstance (and because of the Girl Code), doing so would only hurt Andie more.
- Andie and Dump Truck seem to be developing a relationship, so Liv might actually get a chance with Holden soon enough. Then, Andie finally gives Liv permission to seek Holden, and Liv asks Holden out. Then, Liv's chances are screwed over again because of a slew of problems: A sudden fan meet and greet (with a boy asking trivial questions regarding specifics on Voltage), then Parker asks Liv to place her hands in casting, but he paid no attention to the wait time (it was plaster that took 5 hours to dry, not minutes). But thankfully, Holden comes and at least he's convinced Liv wasn't trying to blow him off, and the date goes better than Liv imagined.
Madison "Maddie" Rooney
Portrayed by Dove CameronMaddie is the 2nd kid of the family, being the younger one of the twins. She is an athletic Tomboy that likes to play basketball.
- Academic Athlete: Straight A student and basketball star.
- Adorkable: Sure she's usually tough and confident, but put her in a social situation (such as talking to her crush) and watch her flounder.
- All Women Love Shoes: Despite being a tomboy she slips into this once, brought out her Liv mode. It gets deconstructed because a specific pair of shoes were starting to take over her life.
- Badass Bookworm: In her case, it comes with being an Academic Athlete.
- Blind Without 'Em: Maddie cannot see well without her glasses, meanwhile Liv inverts it by not seeing well with Maddie's glasses. Maddie, however, had far fewer problems compared to Liv's situation.
- Catchphrase: ''BAM! WHAT?!'' There are situations that the catchphrase go defensive or flat (BAM! What have I done?) but in most cases, it is big.
- Character Tic: She snorts when she's laughing. It's really cute, though.
- Competition Freak: Seriously feels the need to constantly one up people, can not stand being beaten and is severely overly competitive.
- Cool Big Sis: To Parker.
- Cool-Kid-and-Loser Friendship: The loser to Liv's cool. Downplayed since she's cool in a special way, and became a state champion.
- Daddy's Girl: She is very close to her father, due to them both sharing traits and interests. They often work together on matters, particularly sports related ones.
- Genius Bruiser: Maddie may not be as nerdy as Joey or as ridiculously smart as Parker, but she is a straight A student. As for the bruiser part, Maddie is very capable of intimidating Joey, Liv, and others, she's a very skilled contact sports player (Basketball and Softball), and she substituted as the teacher of Parker's karate class while the teacher was out.
- Girliness Upgrade: As of Bro Cave-a-Rooney Maddie is under way Girliness Upgrade shifting from a more traditional tomboy look to a more feminine one. Obviously sharing a roof with the girly fashionista Liv Rooney made her taste of fashion rub off on her.
- Hair of Gold, Heart of Gold: Like Liv, she's usually kind and well-meaning.
- Huge Guy, Tiny Girl: With Diggie: there is at least a foot between them.
- Informed Ability: Maddie is supposedly the best player on her basketball team to the point that her being off the team because of an injury caused them to completely lose out on the championship. However in three seasons she or her team are never shown actually playing basketball, and everything involving the team - such as them actually winning winning the championship in Season 3 happens offscreen.
- The Lad-ette: Maddie has her moments showing off the Ladette vibe, sans drinking and sex.
- Lovable Jock: Female example.
- Masculine Girl, Feminine Boy: Maddie's Masculine Boy and Joey's Feminine Boy
- Meganekko: She's a cute sporty girl who can't see without her glasses.
- Never My Fault: She says she can't get a driver's license because the driving school discriminates against people who can't turn left.
- Official Couple: With Diggie until they break up in "Fluggleball-A-Rooney".
- Passionate Sports Girl: She loves basketball and even considers herself a jock.
- She Cleans Up Nicely: She can be just as stunning as, if not more than Liv. Granted as they share an actress.
- Smarter Than You Look: Maddie has shown to be a lot smarter than she's made out to be. In "Frame-A-Rooney", she was shown to have Sherlock Holmes-like deduction when she correctly guessed how Parker and Reggie got their butts stuck to a chair. Needless to say, they were surprised.
- Sore Loser: Okay, she barely looses. But she doesn't take being beaten well.
- Tomboy: She's a jock, tough, over competitive and unbeatable at refigerator roulette. (Parker cheated, okay?!) Also, she's more manly than her nerdy brother and Josh, in contrast to her twin sister. Though, she has a girly streak.
- Tomboyish Ponytail: Her standard hairstyle.
- Tomboy and Girly Girl: The Tomboy to Liv.
- Tomboy with a Girly Streak: She has a hidden Liv mode, which Liv herself lampshades, complete with wild wacky fashion sense, once brought out by Liv with a pair of sparkly high heels. However, it became a problem similar to a drug addiction.
Joseph "Joey" Gilligan Rooney
- Portrayed by Joey Bragg
- Adorkable: His nerdiness makes him the clumsiest and dorkiest person in the family. He is not good at interacting with girls but despite this he has a Stalker with a Crush who is crazy about him.
- Ambiguously Bi: One wonders, when you look at the way he acts around both of the Smalls brothers.
- Big Brother Instinct: Not touched upon to often, but Joey is quite protective of his little brother. He really didn't take it well when he found out that a local jock was just using him to get girls attention.
- Big Little Brother: Joey is significantly taller than Liv and Maddie despite being younger than them.
- Butt Monkey: He's very often the butt of the jokes.
- Catch Phrase: "What. Is. Happening?"
- Crazy-Prepared: Joey had to go to the girls' locker room to find Dump Truck's rabbit. Because of the reaction he'd get being guy going into a girls' locker room, he covers his eyes with his hand and shouts as loud as he can when he enters, that he's only looking for the rabbit. Said misunderstandings end up becoming the least of his concerns, and causes bigger problems for himself and Maddie. Likewise after ruining Maddie's chances of saying goodbye to Diggie, his first response is to put on body armour and not take it off till he was sure she had calmed down.
- Ditzy Genius: While known to excel at math and science and other things people would find nerdy, other than that he's pretty much The Ditz of the family. (Actually thought that chicken and FRIED chicken were totally different and destroyed the house by using a exercise ball to hold the house with hedge clippers as support.) In general, his intelligence lacks common sense.
- Extraverted Nerd: Okay, Joey knows that he's a nerd but especially in later seasons he tries to be cool so hard (and is convinced that he is) that he counts as this.
- Fat and Skinny: Joey is quite chunky in the first three seasons, to Parker's skinny.
- The Friend Nobody Likes: It's clear he's very disliked within his social circle because of his overconfidence and clumsiness. Even Diggie at times reminds Joey that he cannot take him seriously because of this reputation.
- He Cleans Up Nicely: On one occasion when his mother got him a smart suit to wear, his in-universe level of attraction dramatically increased.
- Hidden Depths: He turns out to be a pretty good stand-up comedian.
- Hollywood Nerd: It's even acknowledged on occasion he's not that bad looking. In "Repeat-A-Rooney" while helping pretend to be a Jock, Maddie's impressed to discover he's actually got reasonable toned muscles in his arms (which he attributes to having to carry all his fake medals on his role play uniform)
- Jock Dad, Nerd Son: Pete and Joey, Pete was captain of the Basketball team while in school and hopes his son will on day aspire to sports, while Joey's set against it.
- Like Father, Unlike Son: When Pete was in highschool, he was the Big Man on Campus, a popular basketball player while Joey is horrible at sports and a loner.
- Masculine Girl, Feminine Boy: Maddie's and Willow's Masculine Girl and Joey's Feminine Boy. The two girls are into sports, while Joey is into things like cat T-shirts.
- Middle Child Syndrome: Joey shows signs of this on occasion, feeling ignored compared to his older and younger siblings. See The Unfavourite.
- Moment Killer: if there's a time that Diggie and Maddie wanted to be alone, Joey's right there to push his way in-between them - almost to the point of wondering if Joey's Ambiguously Bi. Diggie finally gets him back in Sky Volt-A-Rooney.
- Momma's Boy: Touched upon occasionally. Joey seems to be the closest of the Rooney children to their mother. Is generally portrayed as a positive and sweet thing.
- Nerd: Classic case: Joey is socially awkward, really bad at flirting, comic-book obsessed, intelligent and has a weird taste in fashion (look at his cat shirts). Of course he wears a pair of Nerd Glasses.
- Nerd Glasses: Common among Hollywood Nerds
- Nice Job Breaking It, Hero!: Joey going into the girls' locker room and avoiding looking like a "sneaky peaker" while searching for Dump Truck's rabbit, but loses control after he got startled and clumsily topples two sets of lockers blocking the exit doors and preventing Maddie from getting to Diggie on time.
- Odd Friendship: With Diggie, though it's clear Joey does like Diggie more than he likes him and despite having practically nothing in common, the two do get along incredibly well. Joey especially likes Diggie and even goes as far as Man Hug him on several occasions.
- The Peeping Tom: In "Champ-A-Rooney", Joey needed to enter the girls' locker room...to retrieve Dump Truck's giant rabbit. As a result, Joey defies this trope by covering his eyes and shouting out loud as he enters. Turns out the only girl in the room was his sister Maddie, who ends up startling him and causes another chain of problems.
- Sensitive Guy and Manly Man: Sensitive Guy to Parker's Manly Man.
- Smart People Build Robots: Is a member of the schools robotics club.
- TV Genius: Lampshaded by Karen when she says that Joey is smart with math and science, but is incapable with everything else, particularly common sense.
- The Unfavourite: Joey sometimes feels this way, being a nerd with one sister being a basketball state champion and the other sister being a Hollywood star. Sometimes, Joey uses this status to his advantage to get away with his antics.
- Why Did It Have to Be Snakes?: Joey is terrified of squirrels.
- Portrayed by Tenzing Norgay Trainor
- Ambiguously Brown: He is rather tan-skinned and doesn't really look white at all, though his whole family is caucasian. Also, his actor is half nepalese.
- Annoying Younger Sibling: Usually likes seeing Joey fail or be humiliated.
- Bungling Inventor: His inventions usually end up backfiring.
- He created a strong glue to fix his bike and other things when they break, it worked very well but only last for a few hours. Thankfully Parker fixed that flaw, but it got him and his friend stuck to the chair he was trying to fix.
- He mixed up his own copy of the beauty products his mother uses, the stuff worked just as well as the stuff Karen buys but has the strong side-effect of horrid hair growth wherever the mixture is applied.
- Child Prodigy: He's good in robotics and apparently teaches three classes in middle school and has officially skipped grades to be in the same high school as his siblings.
- Deadpan Snarker
- Embarrassing Middle Name: Although not revealed to the audience, his middle name is so bad that it caused his best friend to start laughing at him, and he specifically made sure the audience never heard it. The Logo Joke on the credits for "Dream-a-Rooney" has a nice Continuity Nod to this:''The Beef McGravy's Corporation Of North America condemns the unsportsmanlike conduct of participants in the Ridgewood High School "Paws On A Porcupine"contest. Beef McGravy's hereby bans constestants Artemus Guadeloupe Smalls, Joseph Gilligan Rooney, and Parker [Middle Name Redacted] Rooney for life from all Beef McGravy's franchises and their subsidiaries. As a company, we extend our deepest apologies to anyone offended by unscrupulous behavior which took place during the contest. We wish to state publicly that this is not in keeping with our stated corporate mission to preserve truth, justice, beef and gravy.
- Fat and Skinny: Joey is quite chunky in the first three seasons, to Parker's skinny.
- Flanderization: His inventions were originally meant as Characterization Marches On. Later, being a teenage inventor became his defining trait as the things he created became more and more impressive. Also, he went from a quick-witted kid to a Grade Skipper who attends high school at like age 12. (he's a freshman and skipped 3 grades)
- Gadgeteer Genius: Started off as an Bungling Inventor, but later, his inventions often work.
- Genius Bruiser: Downplayed. He is shown to be one of the best in his karate class and repeatedly created robots on his own. One episode have him moved up to be in the same Robotic Science class as his brother, Joey. He starts getting better at sports.
- Grade Skipper: He skipped 3 grades and attends the same high school as his siblings now.
- Guilty Pleasure: He likes Linda and Heather, even though it's a girls show. He didn't want anyone to know but it turns out two of his friends like the show. By the Season 2 finale, it's pretty much become an Open Secret among his family.
- Mouthy Kid: Well, at least he used to be. Before his Flanderization into a Teen Genius, he was the mischievous, cheeky and snarky little bro who is common among Disney Kid Coms.
- The Prankster: The resident troublemaker.
- Sensitive Guy and Manly Man: Manly Man to Joey's Sensitive Guy.
- Shorter Means Smarter: Of the cast he is the smallest, and he puts a lot of effort into his inventions, though they always go awry.
- Smart People Build Robots: Apparently Parker has somehow stolen Joey's robotics talent as it's mentioned nearly Once an Episode.
- Take Our Word for It: His middle name is just too embarrassing for the audience to hear.
- Too Clever by Half: Parker is always confident he can make good inventions, but they end up failing terribly.
- Vocal Evolution: His voice got lower during mid Season 2 because of Tenzing going through puberty. His voice cracking was pretty noticeable.
- Portrayed by Kali Rocha
- All Women Love Shoes: She has a bad case of this, even degrading her dignity to search for a pair of nice pumps from her daughter. (Granted, the daughter in question is the resident fashionista Liv.)
- Amazingly Embarrassing Parents: Sometimes, she does it as punishment.
- Bunny-Ears Lawyer: Despite being awkward, unsure and often missing things, she is very good at her job as School counsellor. So much so, she's promoted to deputy principal in the second season.
- Happily Married
- Sickening Sweethearts: With Pete.
- Portrayed by Benjamin King
- Amazingly Embarrassing Parents: Less so than his wife.
- Big Man on Campus: Was this when he was in high school, and is still very popular with his peers, as shown when he attended a his high school reunion.
- Demoted to Extra: He doesn't appear much in Season 3 and has a more diminished role, due to a job as a college basketball coach. In the latter half of Season 3, he appears in person less, and is usually absent or appears in video chats. He eventually vanishes from the main cast in Season 4, and was replaced by Aunt Dena's daughter Ruby.
- Happily Married
- Jock Dad, Nerd Son: Pete and Joey, Pete was captain of the Basketball team while in school and hopes his son will on day aspire to sports, while Joey's set against it.
- Over Protective Dad: Especially towards Maddie. Diggie is near-terrified of him.
- Put on a Bus: He leaves the main cast in Season 4. That season establishes that Pete opted to go back to Wisconsin to continue his coaching job in Beloit and oversee his house's reconstruction. Replacing him is Ruby.
- Real Men Eat Meat: Well, it *is* the upper Midwest. He has a near passion for barbecuing, and it's implied he doesn't think very much of vegetarians. On one occasion when forced to go on a meat free diet, he resorted to secretly eating massive amounts of take out then burying the bones so his wife wouldn't find out.
- Sickening Sweethearts: With Karen.
- Portrayed by Lauren Lindsey Donzis
- Convenient Replacement Character: During the Season 4 premiere, we find out Pete returned to Wisconsin to oversee their house being rebuilt, and in that same episode, Ruby is introduced, and then replaces Pete in the opening.
- The Slacker: It's heavily implied Ruby doesn't do as well at school. This is why her getting all A's is considered quite an achievement.
- Portrayed by Ryan McCartan
- Beware of the Nice Ones: Diggie is an all around cheerful and friendly guy, who more or less gets along with almost everyone and is quite even tempered. However if you push him too far (even as far as deceiving him) he'll push back, and he is big, strong and at the pinnacle of physical fitness (such that he's more than capable of giving wedgies to people). As Parker found out, you really don't want to get on his bad side.
- Brainless Beauty: Downplayed; he's simply a handsome guy who isn't a complete idiot but still not the sharpest tool in the head.
- The Ditz: There's plenty of things he doesn't understand. He can't understand even simple messages, such as in Shoe-A-Rooney, he went to the fro-yo store without Maddie, because he thought her text message about having to cancel wasn't simple or specific enough. In Flashback-A-Rooney, he had to ask Parker's help in changing the password of his phone. When he wanted to save Maddie from being blown by a fast rotating windmill, it didn't occur to him he could've just unplugged it. Worst of all, if someone mentions Maddie being involved, he'll easily believe it, which is how Parker was able to trick him.
- The Dog Bites Back: After so many attempts to kiss Maddie have been interrupted one too many times by Joey, he finally gets him back by interrupting Joey's and Willow's kiss.
- Dumb Jock: He is nice to get along with, but he's not very bright. Diggie is not stupid, but he easily gets words mixed up, he needs clarification even for simple messages, and he is gullible enough that he easily falls for "Maddie tricks". However, the only people who can't fool or deceive him are Liv and Maddie, because he knows them that well. When Parker tried to pull a fast one on him, it took Diggie a while to figure that out.
- Foil: To Todd. They're both jocks, but Diggie is a lovable nice guy while Todd is a unpleasant jerk.
- Huge Guy, Tiny Girl: With Maddie: he is at least a foot taller than her.
- Lovable Jock: A popular basketball player, but still likable. He's not a Jerk Jock, but he can be uptight if he entrusts Joey with something that his reputation depends on.
- Nice Guy: Really Diggie's pretty sweet, the only people he doesn't get along with are those who are genuinely unpleasant and even then he normally keeps it to himself. However, he's brutally honest towards those he finds embarrassing, such as Artie's hobbies, or Joey when he knows he can't take him seriously.
- Odd Friendship: With Joey. Despite lacking nearly any similarities Diggie and Joey do get along very well, and are good friends.
- Official Couple: With Maddie Until they broke up in Flugenball-A-Rooney.
- Only One Name: Until "Frame-A-Rooney", which reveals that he's Artie's brother and thus his last name is Smalls.
- One Head Taller: With Maddie.
- Punny Name: His name is oddly close to Biggie Smalls.
- Put on a Bus: Goes to Australia at the beginning of Season 3, but unexpectedly returns mid-to-late season, because of the news of "Liv" (whom he knew was really Maddie) dating Josh. To say it concerned him would be a rather huge understatement.
- Stranger in a Familiar Land: Happens to him after he gets back from Tundrabania, his experiences have changed him, and opened him up to the great big world around him. Meaning tiny Steven's Point no longer interests him as it once did. As such he decides to leave again soon after getting back. Unfortunately this leads to him not considering Maddie's feelings, and the two of them breaking up. When they reach an understanding Maddie lets him go to show she loves him, but spending time in Australia became less appealing without Maddie. After seeing a news article of Maddie-mistaken-for-Liv with Josh, it started to concern him.
- Who Names Their Kid "Dude"?: That is, if Diggie is his real name.
- Portrayed by Jessica Marie Garcia
- Abhorrent Admirer: To Joey, who doesn't want anything to do with her whatsoever. As creepy as it was for Joey, Willow's advances ended up rubbing off on him. When it turned out she was about to leave, he didn't think he'd actually miss her.
- Cloudcuckoolander: One of the the biggest examples in the series.
- The Lad-ette: A tough, big, aggressive girl who's part of the basketball team.
- Lovable Jock: She has a soft side and is a good friend to Maddie.
- Stalker with a Crush: To Joey, to the point it got creepy.
- Tomboy with a Girly Streak: She is boy crazy to Joey. Also if she is excited she squeals just like every other girly girl.
- Portrayed by Cozi Zuehlsdorff
- Portrayed by Jimmy Bellinger
- Abhorrent Admirer: To Liv, because he knew Maddie was dating his brother, so he figured he could have the other twin.
- Academic Alpha Bitch: A Rare Male Example. He always tries to be intellectually better than everyone.
- Alpha Bitch: Again, a Rare Male Example. He has the characteristics befitting of one—huge ego, complete with a Boy Posse who worship him the same way a female Girl Posse would, and Artie thinks he's the most popular kid in school.
- Always Someone Better: Is sometimes this to Joey.
- Annoying Younger Sibling: Diggie is quite embarrassed to have Artie as a brother, because of Artie's annoying hobbies and habits.
- Casanova Wannabe: He tries to attract his Liv with incredibly lame pick-up lines/puns, which really annoys her.
- Card-Carrying Villain: This line very much says it all:Artie: How was I to know this school would respect honesty? It's disgusting!
- Chekhov's Skill: Artie's excellent cooking, which was a point of competition for Maddie in "Cook-A-Rooney", becomes important again when Artie is asked to help Karen make a wonderful Christmas meal.
- Everyone Has Standards: Even Artie is upset at Diggie going away too much. In Diggie's defense, it's because Artie's hobbies are quite embarrassing.
- Friendly Enemy: To Joey, at times. They even have worked together on occasion.
- It's All About Me: The source of his and Joey's rivalry, its revealed they were once in a band together, however Artie's ego kept causing him to self promote till Joey broke it up.
- Lazy Bum: Artie is unrealistically lazy that he relies on his minions for almost everything, like his locker combination.
- Not-So-Harmless Villain: Generally comes across as a comical rival to Joey, however on occasion Artie proves he really is quite bright, his display of supreme cunning even caused Liv to dub him an Evil Genius.
- The Rival: To Joey, but it's implied he doesn't hate him as much as he claims.
- Rivals Team Up: Sometimes, they will work together, because the one thing they have in common is their desire to win.
- Screams Like a Little Girl: For someone so smug and full of himself, he has a girl scream.
- Sitcom Arch-Nemesis: To Joey. He's also this to Maddie because she didn't pick him in her dodge-ball team, and even blamed Maddie for breaking up with his brother.
- Small Name, Big Ego: He thinks that he's incredibly handsome and popular. Well, the truth is less glamorous...
- Supreme Chef: As revealed in "Cook-A-Rooney" he regularly gives Liv gourmet treats as a sign of affection and is top in his home economics class. He also helped Karen make a big Christmas meal in "Joy to-A-Rooney".
- Stereotype Flip: While still a nerd, Artie acts much closer to a Gender Inverted Alpha Bitch, constantly mocking and belittling Joey, even complete with his own Boy Posse. He falls short of being a Jerk Jock, because he's very lazy and bad at sports.
- Portrayed by Victoria Moroles
- All Girls Want Bad Boys: Andie has taken an interest in Dump Truck, the school's local troublemaker and vandal. She even wore Dump Truck's leather jacket in Ridgewood-A-Rooney.
- The Blacksmith: Female example. Andie does a lot of metal and stoneworking as a hobby.
- Her Boyfriend's Jacket: Dump Trucks leather jacket, to be exact. D'awwwww...
- Innocently Insensitive: Andie just immediately dated Holden without consulting Liv, which became a source of drama for them.
- Outnumbered Sibling: Andie is the only girl in her family with five brothers.
- Tomboy and Girly Girl: Tomboy to Liv's Girly Girl.
Dump Truck/Marion Truckberg
- Portrayed by Shak Ghacha
- Affably Evil: He may be a troublemaker who is intimidating and has a fearsome reputation, but he's quite nice, sensitive and respectful to those who impress him, especially to Parker. Even when he threatens Joey, he's polite. He's also displayed a bit of a soft, romantic side in relation to Andie.
- Archive Binge: After becoming aware of Bits and Pieces, he binge-watches the entire show in a very short span of time.Joey: Are you... are you crying?
Dump Truck: [wiping away tears] I just watched the episode of Bits and Pieces where Liv shows Todd Stetson what a girl is.
Joey: Oh... oh, buddy, that is a tough one. Gets me every time.
- Audience Surrogate: Functions as one in the series finale, up to and including becoming a fan of the show itself.
- Berserk Button: Street magic, no questions asked. Also, don't lose his rabbit, because if you do, he can beat you up.
- Bunnies for Cuteness: Played with. He has a pet rabbit, but it's a giant rabbit and he's very protective of it.
- The Bully: Downplayed. The only person he ever bullies is Joey, and threatens to beat him up on a regular basis, but even his threats are polite.
- Delinquent: Dump Truck gets in trouble with Kneebauer quite frequently. Dump Truck does try doing something legit in "Ask Her More-A-Rooney", by being a library book collector. By the end of Season 3, he's gotten into detention less.
- The Dreaded: Affably Evil aside, he has a reputation of being such towards geeks, who run in terror when they see him. Joey is often afraid of getting on his bad side, and Josh was afraid of getting beat up by Dump Truck for getting his name wrong.
- Dumb Muscle: He's all brute, street smart, but not book smart, and he doesn't understand physics terms.
- Embarrassing First Name: His first name is "Marion". No wonder he game himself the nickname Dump Truck.
- Even Evil Has Standards: Believe it or not, he has strong standards and a code of honor. Dump Truck is a vandal, not a thief, and he wouldn't ride on someone's bike without their permission.
- Failed a Spot Check: Failed to notice that cameras have been following the Rooneys around for four years and filming their every move for the reality show Bits and Pieces, until the series finale where he walks into one of Joey's Confession Cam segments and wonders what the hell is going on. For that matter, this is the first time the audience is made aware of the reality show as well.
- Fire-Forged Friends: He was quite intimidating to Parker when they first met, but he came to respect Parker during detention, that he even went out of his way to invite Parker to an event of his.
- Hidden Depths: Reveals in the series finale that he can speak fluent French.Joey: Whoa, Dump Truck, you speak French?
Dump Truck: Bien sûr, we all have our secrets.
- Insistent Terminology: Dump Truck takes political correctness seriously, that he considers himself a "Shady American" as opposed to a dirtbag, and refers to Girls' Basketball as Basketball played by young women.
- Names to Run Away from Really Fast: Him with the name "Dump Truck" is someone who's a no-good, which is why Andie's dad doesn't want her near him. Since his second appearance however, it's clear he doesn't completely live up to his name.
- Not Me This Time: In "Frame-A-Rooney", Dump Truck admitted to lots past vandalism in the school, but he didn't vandalize the Bobby Butterstick mascot. However, he did take offense at the idea that he couldn't pull off something of that similar magnitude, so he keeps trying to prove Maddie wrong.
- Only Known by Their Nickname: Dump Truck first introduced himself as such to Parker when he was given detention, but "Friend-A-Rooney" reveals his real name to be Marion Truckberg.
- Scary Librarian: Well, scary library collector in "Ask Her More-A-Rooney", but close enough. He doesn't make the rules, but the fact that it's he warning people of the consequences of damaged or un-returned books makes him all the more scarier.
- Second Love: Originally Andie dated Holden. Luckily, she developed feelings for the love substitute Dump Truck.
- Shipper on Deck: After binge-watching Bits and Pieces, he becomes a Mosh shipper, and is suddenly very antagonistic towards Diggie for being the one to end up with Maddie in the end.
- Street Smart: He might be Book Dumb but he's still smart and cunning, the opposite of the TV Genius Joey.
- Portrayed by Josh Swickard
- Appropriated Appellation: The term "Jerktourage" was made up by Willow is an insult to Todd's crew for their sexist ranking of the girl at school by their hotness. Todd later refers to his crew as the Jerktourage when they present him with a cake for his "absiversary" (the anniversary of him developing his washboard abs).
- Evil Counterpart: To Diggie. They're both jocks, but Diggie is a likeable nice guy while Todd is an unpleasant jerk.
- Faux Affably Evil: When he acts nice to anyone, its simply cause he's using them for his own gain.
- For the Evulz: He has no (mentioned) reason/excuse for being the sexist Jerkass he is.
- Hate Sink: He's such an obnoxious Jerkass and hated by the entire cast. There's no way to like him. Or do you have a weakness for sixpacks?
- It's All About Me: Is a vain egomaniac, who goes as far as throwing a party to celebrate his own abs.
- Jerkass: At heart, Todd is honestly just a smug, unpleasant jerk.
- Jerk Jock: Todd's really not a nice guy. He's just blatantly misogynistic against girls, and he even used Parker to impress other girls, and is completely full of himself. When Liv and a group of girls tried to stand up to him, he took it Up to Eleven by forcing Willow to conform, which ended up breaking the girls' spirits.
- The Rival: Diggie makes it clear he absolutely hates Todd, stating that he annoys him (though it may have more to do with his personality than actual rivalry), but Diggie sounds as if Todd has been a thorn on his side for a long time.
- Portrayed by Lucas Adams
- Adorkable: Especially when put into situations he's not familiar with, or when he's interacting with Maddie.
- Audience Surrogate: In Season 3, Josh is one for the target audience, especially for those unfamiliar with what goes on in the show. In every episode he's appeared in, he's closest to those involved in the main plot, is usually clueless as to what's going on, and asks questions about what goes on as he bears witness to the events. He eventually grows out of this role in mid-Season 3 and gets promoted to a recurring character.
- Iron Butt Monkey: Josh gets thrown around and beaten a lot, but he can take it.
- Na´ve Newcomer: Josh is a new guy from Hollywood, who earned the part as Liv's costar, but he's quite unfamiliar with the oddness and quirkiness of Stevens Point, Wisconsin. Then it's played with in that despite being from Hollywood, he's a newcomer within the actor/celebrity world. Josh has never been on the red carpet, nor is he familiar with what goes on there. He felt so unprepared to the point where he forgot to put on shoes.
- The Watson: See Audience Surrogate above.
- Why Did It Have to Be Snakes?: Josh is deathly acrophobic.
- Portrayed by Jordan Fisher
- Official Couple: With Liv until they broke up in "Scoop-a-Rooney
- Satellite Love Interest: He's a rather Flat Character, beside his hobbies, tendency to get distracted by anything weird, his love for honesty we don't know much about him, the latter is his only real trait we get to see on screen. He primarly exists to be Liv's Love Interest and to cause the Love Triangle Liv-Andie-Holden.
- Will Not Tell a Lie: especially when he broke up with Andie on live TV. Ouch!. He doesn't want to hurt others' feelings, but he finds it unethical to bring himself to lie.
Astrid "Stains" Stanislovski
- Portrayed by Bridget Shergalis
- Embarrassing Last Name: If you thought her nickname was embarrassing, her last name (where she gets "Stains" from) is even more embarrassing.
- The Klutz: She's a bit clumsy, even when she plays basketball, the reason, why she always has to sit on the bench during games. But she's still likeable and accepted among her teammates.
- Teens Are Short: Believe it or not: her actress Bridget Shergalis was born in 1989, so she was already about 23 years old when she played sophomore Stains during season one in 2013. But, because she's really short, she looks young enough—- or did you notice that Stains was about 6 years older than Liv and Maddie?
Valarie Samantha Wishart
- Ship Tease: It's She and Parker get this a lot, and it's implied they have feelings for each other due to spending more time together. Parker says they're friends-ish.
- Suspiciously Similar Substitute: At first, she seems like one to Alex, also being Parker's intellectual equal and science rival, but Parker feels there is something...special and different about Val.
