Sibling Yin Yang / Western Animation

Examples of Sibling Yin-Yang in Western Animation.

---

• The Amazing World of Gumball: The titular Gumball is a reckless, Book Dumb hedonist, whereas his little sister Anais is a studious, level-headed Child Prodigy.
• Steve and Hayley in American Dad!. The former is a rather overemotional and anxious Stereotypical Nerd, while the latter is a laid-back, collected Soapbox Sadie.
• Arthur: The titular Arthur is normally laid-back, friendly, and reasonable, while his younger sister D.W. is often selfish, bratty, and condescending.
• Avatar: The Last Airbender:
  • Katara and Sokka. The latter is sarcastic, cynical and The Smart Guy, while the former is the open, idealistic Team Mom.
  • The Hot-Blooded Zuko and the cool, manipulative Azula are as different as red and blue. While Zuko learned the basics of firebending, like breathing techniques, Azula is a Child Prodigy who focused on the more glamorous aspects, like blue fire and lightningbending. Zuko ultimately learns to value his friends, while Azula tried to control them with fear, which ultimately gets her betrayed.
  • The series also contrasts Iroh, who raised his nephew Zuko like a son, and Ozai, who mistreated and banished him.
  • Mako and Bolin grew up on the streets, but while Mako is a broody, dark, Troubled, but Cute firebender devoted to winning the probending league and protecting his little brother, Bolin's a boisterous, fun-loving, earthbending ladies' man.
  • Tenzin's daughters Ikki and Jinora. Jinora is a well-read Shrinking Violet and the Girly Girl to Ikki's garrulous, high octane Tomboy personality.
  • Tenzin has this relationship with his older siblings, Kya II and Bumi II. When they were children, Tenzin was very serious, while his siblings were rather rambunctious. In the present, Tenzin is serious (usually), bald, burdened with a large responsibility, and monk-like while Bumi is "a wild man" in the armed forces of the United Republic with a head full of Anime Hair; meanwhile, Kya is unmarried and traveled all over the world to "find herself" (which Tenzin saw as abandoning her family), while Tenzin settled down and had a large family. Tenzin and Kya are also elemental benders with deep spiritual ties, while Bumi is a Bad Ass Normal^note until Harmonic Convergence, when he acquired airbending military man/walking disaster area.
  • Between Korra's father Tonraq and her uncle Unalaq. The younger brother, Unalaq, is ambitious, focused on spiritual concerns, and feels driven to lead his people, while the older brother, Tonraq, is unambitious, focused on physical strength, and decidedly non-spiritual. Then it's revealed that Unalaq is a madman and got Tonraq kicked out of his tribe.
  • Lin and Suyin Beifong. Lin highly values law and order, never wanted children and is generally very cold, serious and bitter. Suyin, on the other hand, was a teenage rebel, and still does not like authority too much, but highly values family, having five children of her own, and appears to be rather warm and open toward other people.
  • Desna is the Only Sane Man as he becomes concerned about his father's Evil Plan, while his twin sister Eska is the more abusive psycho towards Bolin.
  • Suyin's children: Huan is the Emo Teen, Wei and Wing are Bash Brothers, Opal is sweet and honest, and Bataar Jr. is, well, The Dragon to his fiance Kuvira, let alone being a jerk towards his mother, who considers him as a Black Sheep of the family.
  • Noatak/Amon wants to take over Republic City out of a genuine desire to bring equality between benders and non-benders. His brother Tarrlok is purely interested in gaining political power for himself. Their approach is also markedly different; Tarrlok is a politician using the crisis to more or less legally consolidate power, while Amon is a terrorist advocating the violent overthrow of the government
• Finn and Jake from Adventure Time. Finn is an optimistic and off-the-walls energetic Badass Normal, and his adopted brother Jake (who’s also a dog) is a super-powerful but lazy couch potato with a more realistic view of life who tags along on adventures mostly to make Finn happy
• Bluey downplays this with Bluey and her younger sister Bingo; while they're both cheerful and exuberant young puppies who share a lot of the same interests, Bluey tends to be more vocal and outgoing, while Bingo tends to be more sensitive and has more trouble speaking up when she feels upset. "Mini Bluey" highlights a few more differences between them, namely that Bluey is messier and doesn't like to help out with chores while Bingo is tidier and doesn't mind helping her parents when they ask her.
• The Belcher kids on Bob's Burgers. The eldest daughter Tina is anxious, soft-spoken, and self-effacing, although boy-crazy. The youngest daughter is a snarky Large Ham and proud schemer. Between them is the lone son Gene, a scatterbrained Cheerful Child.
• Huey and Riley in The Boondocks. Riley is more foolish and impressionable, tends to act rashly and desperately wants to be a "gangster", while Huey is responsible, levelheaded, and deeply contemplative.
• The Interesting Twins From Beneath The Mountain in Codename: Kids Next Door; "Sister" is domineering and driven by emotion, while "Brother" is more reserved and rational. To drive the point home, the birthmarks on their faces are literally the two halves of Yin and Yang.
• Danny and Jazz in Danny Phantom. Danny is insecure, rash and powerful, while Jazz is book-smart, confident and collected.
• Daria and Quinn in Daria. Daria is a snarky, cynical, intellectual girl, Quinn is a shallow, vain Lovable Alpha Bitch.
• Dexter is a Child Prodigy and Dee Dee is The Ditz in Dexter's Laboratory, although Dee Dee has been portrayed as actually being smarter, or at least more experienced, on occasion.
• Zack and Wheezie of Dragon Tales are the Savvy Guy, Energetic Girl type. Not only that, but they are also two halves of a two-headed dragon.
• The brothers Dijon and Poupon in DuckTales (1987). Dijon is an Ineffectual Sympathetic Villain with Sticky Fingers, whereas Poupon is a virtuous monk and a member of the order that guards the Golden Goose.
• Sarah, a Tiny Tyrannical Girl with a Hair-Trigger Temper, and Ed, a Gentle Giant Ditz, in Ed, Edd n Eddy.
• Vicky, a complete sadist, and Tootie, a sweet if somewhat clingy girl, in The Fairly OddParents!. While Vicky likes tormenting the main protagonist Timmy Turner, Tootie loves Timmy Turner with a passion.
• Family Guy:
  • Chris is a Fat Idiot like his father, while Stewie is a Brainy Baby and Evil Genius. Meg has this with both of them, to some extent.
  • Lois and her younger sister Carol. Lois comes off as an assertive Jerkass in an unhappy marriage with a Fat Idiot, while her younger sister Carol is a meek, Nice Girl who has problems keeping a man.
• PJ and Pistol on Goof Troop. PJ is rational, conciliatory, timid, and somewhat melancholy due to being emotionally abused. Pistol, on the other hand, is hyperactive, bratty, talkative, and very cheerful... which may be because she's spoiled. Strangely, episodes that play them as Satellite Characters to one of their parents show them agreeing surprisingly often.
• Gravity Falls:
  • The Pines Twins: Dipper is The Smart Guy with a slight cynical side, while Mabel is energetic and a Cloudcuckoolander.
  • The elder set of Pines twins, Stanford and Stanley, contrast even more. Stanley was a lazy joker who had dreams of going on adventures and finding his fortune, while Stanford was a serious student who wanted to go to a good college and explore the supernatural For Science!. As they grew older, Stanley became a Con Man who shunned anything supernatural, while Stanford's explorations nearly made him Go Mad from the Revelation but never stopped him from continuing his research, much to Stanley's annoyance and ultimately the world's detriment.
• Hey Arnold!: Helga and Olga Pataki. Neither one of them turned out too well due to their parents, but Helga is an angry Tsundere who bullies others, often unconsciously, whereas Olga is a perfectionist, a Stepford Smiler, and a Nervous Wreck.
• Ang and Ling in Legend Of The Dragon. Ang is an easy-going, self-effacing hero, and Ling is an intense, ambitious Anti-Villain (later Anti-Hero). She even gets her powers from "the darkest Yin".
• The Loud House:
  • Girly-girl/Beauty queen Lola and tomboy/dirt-loving Lana are twin sisters.
  • In contrast to the Loud parents, Mrs. Maria Santiago has only two children: Bobby and Ronnie Anne. These two couldn't be more different, and not just in terms of gender. Ronnie Anne is a tomboyish Loving Bully to Lincoln, while Bobby is an all-loving Nice Guy who is In Touch with His Feminine Side and treats Lori with respect. Ronnie is also smart and can be a cunning schemer when she wants to be, while Bobby is very much a Kindhearted Simpleton.
• Miraculous Ladybug:
  • Twin siblings Luka and Juleka. Juleka is quiet and shy, Luka is laid back and sociable.
  • Chloé and her half-sister Zoé: Chloé is the Alpha Bitch, Zoé is actually nice.
• Mission Hill: Andy and Kevin French. The former is a Street Smart slacker who is quite savvy and able to be quite brilliant on the fly when the scenario calls for it, all the while being a sarcastic snarker and complete womanizer. The latter is an absolute genius at academics but so socially inept and sheltered he can hardly fend for himself outside of the classroom, and an overly enthusiastic mommy's boy. Andy is openly an Ethical Slut but completely willing to leave a woman hanging just to look out for his brother, while the latter claims to be against anything even remotely sexual but is secretly enthralled by pornography.
• ¡Mucha Lucha!: The Flea and Pulgita, the latter being the sane man to the former.
• My Little Pony:
  • My Little Pony: Friendship Is Magic:
    • Princess Celestia and Princess Luna. Celestia, who controls the day, is gentle, motherly, and a bit mischievous, while Luna, who controls the night, is stern, overly formal, and a bit bad-tempered (as seen in "Luna Eclipsed"). That may be a side effect of being sealed in the moon for a thousand years, though. (It's eventually revealed that part of Luna's behavior is due to the guilt she feels over her time as Nightmare Moon.)
    • Pinkie Pie and her sister Maud. Pinkie's a brightly-colored Fun Personified ball of Attention Deficit... Ooh, Shiny! energy. Maud's a grey-colored, rock-obsessed Emotionless Girl.
    • As seen in "Hearthbreakers", this goes for Pinkie's other sisters as well. Pinkie is friendly, welcoming, and fun-loving, while Limestone is gruff, bad-tempered, and serious. Pinkie is talkative and outgoing, while her twin sister Marble is quiet and bashful.
  • My Little Pony (Generation 5): The pegasus siblings Pipp Petals and Zipp Storm share a Tomboy and Girly Girl dynamic, with Zipp being a Rebellious Princess and dissatisfied with the ruses the royal family puts up and Pipp being a popular Idol Singer who's entirely satisfied with their current lifestyle.
• Over the Garden Wall: Wirt is a shy Only Sane Man who occasionally lapses into melodrama and despair, while his younger half-brother Greg is a kooky Cheerful Child who refuses to ever give up.
• The Owl House: Amity is a responsible, level-headed bookworm who starts off as antisocial but becomes more open with the help of Luz. Emira and Edric are Trickster Twins who are more carefree and fun-loving, although they do become more grounded over the course of the series.
• Phineas and Ferb:
  • Phineas and Ferb, though they share the love of inventions, tend to contrast each other in some ways, though their differences seem more complementary than opposed; Phineas is the more talkative ideas guy while Ferb is The Quiet One who builds all the inventions Phineas thinks up. For that matter, either/both of them contrast their older sister Candace, a shrill Nervous Wreck who wants nothing more than a quiet, unexciting summer, and will go out of her way to try and get the duo caught by their parents.
  • There's also Dr. Heinz Doofenshmirtz and his brother, Roger. Heinz is a bumbling, incompetent Mad Scientist and The Unfavorite of his mother, while Roger is The Ace, mayor of Danville, and favored by his parents to comedically exaggerated levels.
• The Powerpuff Girls have Buttercup, a tough angry tomboy, and Bubbles, a gentle Girly Girl, who almost never gets mad. Blossom is somewhere between them personality-wise, but she also is the most intelligent one.
• Puppy in My Pocket: Adventures in Pocketville: Ava is older,^note presumably, as she's the monarch and lines of succession traditionally go to whoever's the eldest child of the monarch. girly, and kind to her subjects and is very naive. Her twin Eva is younger, tomboyish, and incredibly brave, but absolutely cruel towards everyone, including her own lackeys and especially her sister.
• Ready Jet Go!: : Celery contrasts with her brother, Zucchini. Celery is a very good driver and is also quite smart, having a job as a travel writer. Zucchini, on the other hand, has a job as a garbageman and is quite dumb from time to time.
• Reboot: Megabyte and Hexadecimal are two virus siblings. Megabyte is egomaniacal, sophisticated, well-mannered, calm and collected, and designs complex plots to conquer Mainframe and place it under his orderly rule. Hexadecimal is sporadic, prone to wild mood swings, and loves chaos for the sake of chaos.
• Regular Show: Rigby is a rude, childish slacker who never received his high school diploma. His younger (albeit much taller) brother Don is a mild-mannered, collected Nice Guy who grew up to be a successful accountant. However, Rigby does get better and finally receives his high school diploma in the season 7 finale.
• The Simpsons: Bart is a lazy delinquent, while Lisa a socially-aware academic. Incidentally, their parents contrast each other similarly.
  • Homer and his half-brother, Herbert as well. Homer is a lazy, Bumbling Dad who plays the pivotal role of ruining his brother's life. Herbert was more successful, possessing the confidence and leadership Homer lacked. Unfortunately for Herbert, he placed too much faith in his half-witted relative costing him everything he owned.
• Sofia the First: Baileywick and his brother Nigel. Baileywick is a sophisticated steward who makes sure he does his job well, while Nigel is a boisterous man who still treats him like a "baby brother" and likes teasing him.
• South Park: Stan is (usually) very mild-mannered and easygoing, whereas his older sister Shelly is extremely hot-headed and borderline unstable.
• Star Wars: The Clone Wars:
  • The Daughter and the Son are literal examples of this trope, as they are representing the Light and The Dark Side of the Force respectively.
  • It is revealed as of "Lawless" that Satine and Bo-Katan are this in the more general sense. Despite their differences, however, the latter was very much broken up when the former was killed.
  • Savage Oppress and Darth Maul are this as well. While they are both powerful and clever Sith warriors, the former, while far from stupid, is not much of a thinker, bluntly straightforward, honorable despite his darker nature, and content with staying in his brother's shadow. In contrast, Maul, while very much a fighter, is much more cunning, charismatic, manipulative, cruel, and ambitious. Despite the potential for a betrayal on Maul's part, both brothers genuinely do care for one another, and Maul's reaction to Savage's death by Sidious's hand is both grief and anger.
• Storm Hawks: Among the two Cyclonian siblings, Ravess is a cultured perfectionist and Snipe is a gluttonous slob. Repton and Lugey could count too: Repton is a cunning, brutal and vicious ringleader whilst Lugey is a dim-witted, oafish and Affably Evil subordinate.
• In Street Fighter, Akuma and his brother Gouken (Ryu and Ken's martial arts master). Gouken was happy that he and Akuma were chosen by their master to be training partners, as they were the first set of siblings in their school's history to be paired up like this. Akuma was less than thrilled since this only emphasized how different they were. Their master paired them up specifically because they were almost polar opposites since their school's philosophy stated that this was the best way to encourage growth. Gouken was as peaceful as Akuma was vicious. This is true to the source material: Gouken purged their school's martial art of its murderous aspects, while Akuma embraced and refined them.
• Teen Titans:
  • Starfire and Blackfire. Starfire is nice and sweet. Blackfire is cruel and sinister.
  • The thoughtful, pacifistic, somewhat clingy Thunder and hotheaded, independent, pyro/electromaniacal Lightning.
• The Transformers: Autobot brothers Sideswipe and Sunstreaker are both excellent fighters and Bash Brothers, but Sideswipe is a good-natured Boisterous Bruiser while Sunstreaker is a cold-hearted narcissistic jerkass.
• Hank and Dean, the eponymous Venture Brothers, have grown to become this in later seasons. Dean is a nerdy, frail, non-confrontational Non-Action Guy who is being groomed for a career as a super scientist, while Hank is an underachiever and wannabe Action Hero.
• Yin Yang Yo!:
  • Yin and Yang coping with each others' differences is quite a major part of the series. Basically, Sibling Yin-Yang with their names literally being Yin and Yang. While Yin is studious, feminine, and a magic user, Yang is rather idiotic, rough, and prefers to use might over magic.
  • Carl and Herman, with Carl's magic and strategy being contrasted by Herman's muscle and brute force. "Dojo Alone" showed that, if they ever worked together, they'd be unstoppable, but they can't stand each other.
• Wakfu: Evangelyne and Cleophee. Eva is a smart, sensible and tactical archer, while Cleo is more reckless and prefers hand-to-hand combat.
• W.I.T.C.H.: The royal siblings of Meridian. Elyon is sweet, lighthearted, cheerful, and loving, and genuinely wants to help her people, while Phobos is cruel, cold, and evil, draining power from Meridian and imprisoning anyone who disagrees with him.
