Western Animation: Yin Yang Yo!
Yin Yang Yo
"In a world of chaos and disarray
Brother and sister save the day!"
"When might and magic work as one
A villain's plan can be undone!"
is an Animated Series
which aired in Toon Disney
's Jetix block (later Disney XD
). It retains the same creative team behind Nickelodeon
's The Fairly Oddparents
and Danny Phantom
so naturally there are quite a few similarities
Yin and Yang are twin rabbits: Yin, the studious and socially aware girl, is constantly mortified and embarrassed by her dirty, disheveled, violent, greedy and self-indulgent (but still miraculously on the side of good) brother, Yang. Together, they study the ancient art of Woo Foo under the tutelage of the grumpy old panda Master Yo
, who once had his own Woo Foo glory days.
Yin's studies are Woo Foo magic while Yang's are Woo Foo combat, hence the "might and magic" standard above. They both are eager to prove themselves, partly because they want to master what they've learned, but also because the Big Bad
has rendered it so the entire world
thinks Woo Foo is stupid and laughable. The problem is that, as twins and polar opposites, they get on each other's nerves and get in each other's way often but, when they do finally set aside their differences and actually work together, they prove to be very formidable.
Feel free to contribute to the Character Sheet
This series provides examples of:
- Action Girl: Yin and eventually Lena after she learns how to use Woo Foo.
- Added Alliterative Appeal
- Aerith and Bob: Aside from the titular protagonists who have names derived from the Taoist philosophy, there's normal English names like Dave, Lina, Roger, and Coop. Then there are names like Ultimoose and The Boogeyman.
- Affectionate Gesture to the Head
- In "Dojo Oh No", Master Yo rubs Yin's head to comfort her while she's upset.
- Saranoia also does this briefly in "Bad Nanny Jamma" while assuring Yin will grow up to become successful.
- Affectionate Parody: Incredibly common along with a few Shout-Out moments. Only some include…
- The episode "Wonder Tweens Go!" is just a huge Affectionate Parody of Teen Titans. There’s also Yin's outfit which is also very similar to Sailor Moon.
- Then there's "Camp Magic Pants" which is an obvious parody of Harry Potter.
- "An Inconvenient Tooth" is entirely based off the Looney Tunes shorts of Bugs Bunny and Elmer Fudd. The list goes on.
- All Girls Like Ponies: Or Twonicorns, as the case may be.
- All Girls Want Bad Boys: Yin seems to fall instantly for anyone she knows, if they become tainted with evil. Even Coop the chicken. Especially Coop the chicken. It becomes very plot relevant in "Gone-a-Fowl."
- Alphabetical Theme Naming
- Amazing Technicolor Wildlife
- Ambiguously Gay: Carl, The Evil Cockroach Wizard... mainly because of his accent.
- He once used a giant robot in the shape of a giant pink stiletto-heeled stripper-boot, he's been seen being fitted for a dress by his mother (who the dress wouldn't fit, of course, as she's a dragon (don't ask), with no sign that it was unwilling, and that's just the tip of the iceberg. Carl's accent is the straightest thing ABOUT the character.
- And Now You Must Marry Me: A non-villainous example in "For The Love of Clamboy": Yin accepts the jewel from Clamuel and agrees to be his "super special friend" when all she really wanted was the jewels. According to his tradition, she has to marry him.
- Animation Bump: The animation seems to improve in the second season.
- Animal Battle Aura: A Woo Foo Aura, which is in the shape of the animal that makes it.
- Artifact of Doom: Ironically, most of the power items are in Yo's Woo Foo Armory, but the villains get their hands on it and Hilarity Ensues.
- Artistic License – Biology: All the animal characters such as Yin and Yang, Master Yo, Yuck, Lina (a dog), and Coop would certainly have tails yet none of them do. In addition, there's also the fact some of the characters have floating ears yet can hear out of them just fine.
Master Yo: I'm looking for a couple of children: lazy, pink and blue, ears ain't attached to their heads... no tails.
- In "Yin Yang You", Yin, Yang, Lina, and Carl being trapped inside the real world causes them to slowly change into anatomically correct animals. To all four of them, this is ... less than good. To different degrees:
- Yin and Yang are upset, since they have trouble controlling their "hoppy" legs and can't hold things with their paws.
- Lina is mainly just annoyed, because "talk to the paw" is a terrible Catch Phrase.
- Carl is grossed out over becoming a real cockroach but is too distracted by his latest scheme to pay it too much mind.
- Art Shift: There are a few scenes which are drawn to look like a children's picture colored with crayons:
- "Gone-A-Fowl" has the slideshow done by Yang.
- "For The Love of Clamboy" has a demonstration of the Super Special Friends ceremony also done by Yang.
- "Upstanding Yuck" during Yuck's flashback.
- Bad Future: The premise of "Deja Foo", Yang creates a future where Ultimoose becomes the new Night Master when he found the Amnesulet but he managed to hit the Reset Button on it. When Yang use this as a advantage to start deliberately hurt others in attempt to get revenge, it's even worse when he forgot about the Amnesulet and got Yin and Master Yo killed by Ultimoose in the process! Yang managed to prevent the future from happening by being nice this time around and stopped Ultimoose, with the help of the other villains who Yang was nice to!
- Badass Family
- Badass Adorable: The cute, Technicolor rabbits Yin and Yang who look harmless at first glance but certainly have no problem beating enemies twice their size.
- Badass Teacher: Master Yo
- Balloon Belly: Happens to Yin in "How the Cookies Crumble" and she even has her umbilicus exposed.
- Battle Cry: Quite a few in particular.
- Yang: "Chee, Hoo, Wha!"
- Ultimoose: "HOOH! HAH! HOOH!"
- Barefoot Cartoon Animal: Quite a few characters go around without shoes, particularly the main three.
- Be Careful What You Wish For: While the official Aesop of Mission Yin-possible is "don't jump to conclusions," this trope easily qualifies as a secondary Aesop: the Artifact of Doom du jour, the Fuzzy Pink Slippers of Heart's Desire, will grant you your heart's desire, but they will be bound to you by magic and can't be removed until you no longer want what the Slippers gave you.
- BFS: Smoke’s sword which is nearly as large as she is.
- Big Bad
- The Night Master in season one until he’s defeated in “Night Fall”. Eradictus then takes his place in season two.
- Ferocitus appears in the last episode of season two and seems as though he would have filled the slot for the past villains.
- Blah Blah Blah
Yang: I chop! I smash! I-
Yin: Blah, blah, blah.
- Boobs of Steel: Smoke
- Book Dumb: Yang who shows a few times he’s capable of witty tricks and can get the upper hand against smarter villains when he tries. He simply shows a lack of interest in general education.
- Brains and Brawn: Done between the twins with Yin and Yang, respectively. Although Yin is fairly well strength wise, she's much more reliant on her intelligence and magic and Yang really enjoys to hit stuff along with Obfuscating Stupidity.
- Brick Joke: This series runs on these, but the biggest one comes from ULTIMOOSE: in "The Trouble with Twonicorns", he says he wants to pick up chicks, with his horns showing a baby chicken the last episode of the series has ULTIMOOSE honestly attracting Coop's mom.
- Brother Chuck: After "Welcome to the Dark Tomorrow", Molecu-Lars vanished without any explanation.
- Brother-Sister Team: The titular bunnies.
- Butt Monkey
- Dave who receives a fair amount of beatings and ill treatment from his friends no matter the situation. Ironically, he’s one of the strongest characters due to his ability to speak to trees and use them during battle.
- Carl and Ultimoose are often shunned and mocked by other villains due to their idiocy.
- Catch Phrase:
- Yang: "Hippity hoppity hard", "That's right!", "Pellets!" and "Two words. 'Who' 'Cares'?"
- Lina: "Talk to the hand!"
- Yuck tends to say "I'm back!" whenever he appears again. Towards the end of the episode when he thinks he's going to win he often says "Say goodbye."
- Calling Your Attacks: "Yincinerate! Yangarang! Transfoomate!" et. al.
- Canis Latinicus: "Roboticus Maximus" translates to Biggest/Important Robot.
- Card-Carrying Villain: Nearly every villain in the series addresses themselves as evil but mostly "Carl, The Evil Cockroach Wizard!"
- Chained Heat: Happens to Yang and Carl that kicks off the plot to "Get Off My Back".
- Christmas Episode: "Seasons Beatings"
- Chuck Cunningham Syndrome: Molecu-Lars, one of Eradicus' mooks had an unexplained disappearance after his first appearance.
- Clown School: A fighting variation appears here. Yin and Yang spend the episode learning Clown-Fu, a martial arts based on clowning around. Yo was a former practitioner and Yang accels at it. However, the techniques do not the work on humorless foes (here, the accountants) resulting in the kids using their Woo-Fu to defeat said accountants.
- Comically Missing the Point: Yang has an ongoing habit of doing this in response to Yin’s panic during a bad situation.
- Couch Gag: After the title comes a random line from the episode, often one that sounds horribly wrong out of context.
- Covered in Mud: In "Basic Yin-Stinct", Yin struggles to decide which path of a fork in the road to take while Yang drives them on a scooter. Due to failing to make a decision fast enough, the scooter runs into a tree and sends her flying into mud.
Yin: Mud? I don't land in mud!
- Creepy Doll: The doll Yang wins for Yin in "A Toy Story" is this, only because Zarnot is controlling it from the inside and tries to kill Yang.
- Crystal Ball: Saranoia and Carl both have these to spy on the twins occasionally.
- Cute Bruiser: Being pink and blue bunnies, both twins do qualify.
- Dark Action Girl: Saranoia, Smoke, and Ella Mental.
- Deadpan Snarker:
- Lina, Ella Mental, and G.P.(Fr-ped), specially toward Saranoia the latter.

Edna: Try not to embarrass me.
Carl: Well, it'll be hard to compete with that gown.
- Deflector Shields: Foo Field
- Department of Redundancy Department: "Power doesn't make you evil. Being evil makes you evil!"
- Disproportionate Retribution: Yuck tends to do this a lot.
- In "Yin Yang Yuck!", he decides to walk right in the middle of a busy street, causing cars to crash into each other. When an angry driver honks at him, Yuck replies "Beep at me again. See what happens." The driver does and so Yuck decides to beat the crap out of him.
- Also in "Yin Yang Yuck!", when Master Yo refuses to train Yuck, Yuck responds by trying to kill him.
- In "Imperfect Fooplicates", a fooplicate claims that he doesn't want to go to the ice cream shop, the place Yuck ordered they go to. Yuck's response: throw a blast at him and yell "You'll do what l say!"
- Does This Remind You of Anything?: Amongst many edgy jokes in “Fighting Fooberty”, Yang’s jittery, eager response to Lina is incredibly similar to a boy experiencing arousal.
- Doomy Dooms of Doom

- Dramatic Drop: Yo, on the occasion of realizing his students are about to let Sealed Evil in a Can out.
- Dramatic Thunder: Used at the end of "Upstanding Yuck" when Yuck becomes evil again.

- Even Bad Men Love Their Mamas: Both Carl and Herman love Edna and try to impress her through their evil deeds.

- Flying Broomstick: Used in "Camp Magic Pants".
- Footsie Under the Table: Yang and Lina do this in "For The Love of Clamboy" while doing research about the life of clams. When Yang finds a startling fact, this conversation stirs up:

Lina: No, it's Lina. You didn't think you were playing footsies with your sister, because that is weird.
- Fountain of Youth: Master Yo
- Four-Fingered Hands: used but subverted with the Manotaur who has five instead.
- Fun with Acronyms: In an attempt to stop Yang from advertising dangerous toys, Yin decides to form an alliance against him titled Mothers Against That Jerk Yang. When trying to shorten it into an acronym, she obviously struggles to pronounce it. A woman standing by then suggests they title it "S.A.M.A.N.T.H.U.H".
- Furry Reminder: Though not always, there are a few subtle elements of this. During "Mission Yin-Possible", Yin states that her and Yang could get over the lasers by jumping. Yang looks at her with a confused expression before bluntly reminding them that their rabbits.
- Yang stomps his foot repeatedly during "Fighting Fooberty" which can be a sign of excitement.
- Yin and Yang's ears can be rather expressive when frightened, alert, happy, or sad.
- "Yin Yang You!" is practically built on this with the cartoonish aspects of Yin, Yang, Lina, and Carl becoming realistic and annoying them due to their inconvenience. In fact, this is the only episode that identifies Lina as a dog.
- Getting Crap Past the Radar: Various.
- Yang yelling "Pellets!" whenever he's annoyed in general.
- The sheer amount of time they use the word "sucks" (as in "This sucks!!") is mind-boggling, especially for family friendly Disney.

- In "Master Dave", Yang exclaims at the beginning of the episode, "Go for the nuts, Yin. I mean the bolts too, but go for the nuts."

- In "The Hex of the Ex" Yin is going through a montage of rejecting Coop. The final scene shows theme in a fiery area, where Yin states "It has not, as of yet frozen over.
- Good Angel, Bad Angel: Yang has this in "Deja Foo".

- Halloween Episode: "The Howl of The Weenie"
- Hammer Space: All of the characters seem to have this but especially Yang who can pull out his sword at any time.

- Heart Symbol: Yang leaves them behind him [where a cartoon character would ordinarily leave a puff of smoke] as a wake when he realizes his crush likes him back.

At the end of the episode, moved by how good Yin and Yang had treated him, he removed his disguise, says that he doesn't want to be evil anymore and be friends with them. He's kicked out.

- Invisibility: well, Yinvisibility and Yangvisibility.
- Involuntary Dance:

- Yang is often called one due to his immaturity and selfish nature during certain moments, but he does show he can befairly nice after learning a lesson.

- Never Say "Die": Destroy is a common replacement for the villains though “die” is often used during more serious moments.
Master Yo: You could have been killed!
- There's also in "Yin Yang Who?" after Yin jumps in front of a Woo Foo Aura Drain, she's aware that she'll die soon.
Yin: That was the Aura Drain and now I'm gonna d...di...
Oh great, and now I'm gonna yack. Bucket!

- Averted again this time by Badfoot who wears two convincing disguises in "Old Softie".
- Parental Abandonment: Yin and Yang's rabbit parents have not made an appearance so far, Master Yo is their only parental figure.

- Smorking: As a parody of The Smurfs, the Smorks do this constantly.
- Split Screen
- Stalker with a Crush: Coop constantly attempts to spy on Yin and ask her out on dates only to be shot down. Also Yang whose more subtle than Coop, but makes plenty of advances on Lina that she finds more odd than charming.

- Twinkle Smile: When Yuck appears in "Upstanding Yuck", there are a few quick shots of his now clean self including one of his teeth sparkling.
- Unusual Euphemism: "Pellets" and "hippity-hoppity hard" are pretty common phrases used by both Yin and Yang to express anger or annoyance. There's also quite a few ways of saying "Foo" such as "mother of Foo" or "what the Foo".

- Herman's allergic reaction to panda fur. There is exactly one panda left, but still.
- Witty Banter: There's a small exchange in "Personality Problem" about this.
Yang: So, should we start with some witty banter or just bring the pain?
Yuck: Pain is good. Especially when I'm serving it-Ha! And I'm serving it up BIG TIME!
