10	''Yin Yang Yo!'' is a 2006 Canadian-American AnimatedSeries produced by Jetix as its third original series (after ''WesternAnimation/SuperRobotMonkeyTeamHyperforceGo'' and ''WesternAnimation/GetEd'') for its programming block on Creator/ToonDisney (later Creator/DisneyXD) in the United States and Creator/FamilyChannel in Canada. It retains the same creative team behind Creator/{{Nickelodeon}}'s ''WesternAnimation/TheFairlyOddParents'' and ''WesternAnimation/DannyPhantom'' so naturally [[SignatureStyle there are quite a few similarities]]; in addition, the animation style is very reminiscent of ''WesternAnimation/WowWowWubbzy'' due to both shows sharing the same creator, Bob Boyle.
11
12	Yin and Yang are twin rabbits: the former, [[BadassBookworm a studious and socially aware girl]], is constantly mortified and embarrassed by her dirty, disheveled, [[BloodKnight violent,]] [[JerkWithAHeartOfGold greedy, and self-indulgent (but still miraculously on the side of good)]] brother, Yang. Together, they study the [[SupernaturalMartialArts ancient art of Woo Foo]] under the tutelage of the grumpy [[OldMaster old panda Master Yo]], who once had his own Woo Foo glory days.
13
14	Yin's studies are Woo Foo magic while Yang's are Woo Foo combat, [[SwordAndSorcerer 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 BigBad has rendered it so ''the entire world'' thinks Woo Foo is stupid and laughable. The problem is that, [[PolarOppositeTwins 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.

18	!!Yin! Yang! Tropes!:
19
20	[[foldercontrol]]
21
22	[[folder:Tropes A - H]]
23
24	* ActionGirl: Yin is the [[SwordAndSorcerer sorcerer to Yang's sword]] and something of a KungFuWizard at that, being able to mesh magic as well as having an impressive amount of strength for her girl her age.
25	** Lina doesn't have the ability to harness Woo Foo [[spoiler: at first]] but she tends to step up to a fight if she feels its necessary, especially if Yin and Yang can't seem to handle it.
26	* AdBreakDoubleTake: This occurs OnceAnEpisode.
27	* AddedAlliterativeAppeal: The shows title which is composed of the three main characters names, all conveniently beginning with the letter "Y"
28	* AdultsAreUseless: Yo. He's a neglectful parent who wishes to avoid having to do any childbearing work for Yin and Yang. He also doesn't seem too worried about his hometown being invaded by evil, instead forcing his own children to handle it.
29	* AerithAndBob: 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 [[SpellMyNameWithAThe The Boogeyman]].
30	* AesopAmnesia: Generally averted, as CharacterDevelopment means they usually don't make the same mistake twice. However, they tend to slip up every now and then when it comes to working together (albeit the circumstances and reasons why keep it from being boring).
31	* AffectionateGestureToTheHead: Yin gets her head pet in reassurance from Master Yo in "Dojo Oh No", Saranoia in "Bad Nanny Jamma", and The Lesson from "Attack of the Vidiots".
32	* AffectionateParody: The show itself can be seen as a spoof of martial arts movies. For every piece of genuine lore there's just as many silly artifacts, a massive RoguesGallery filled with many the IneffectualSympatheticVillain, and the fact the story is told from the perspective of two tiny rabbit children rather than the usual stoic badass protagonist.
33	** This is also incredibly common along with a few ShoutOut moments, only some include:
34	*** The episode "Wonder Tweens Go!" is just a huge AffectionateParody of ''WesternAnimation/TeenTitans''. There’s also Yin's outfit which is also very similar to Franchise/SailorMoon.
35	*** Then there's "Camp Magic Pants" which is an obvious parody of Literature/HarryPotter.
36	*** "An Inconvenient Tooth" is entirely based off the WesternAnimation/LooneyTunes shorts of Bugs Bunny and Elmer Fudd with Expies of other characters appearing as cameos (such as Foghorn Leghorn-like Turkey).
37	** "Old Softie" is clearly a take on Film/WillyWonkaAndTheChocolateFactory
38	* AllGirlsLikePonies: Or Twonicorns, as the case may be. Yin is an avid fan of the toy-line as well as the real life creatures they're based off of. She collects small plastic replicas that she plays with like dolls.
39	* AllGirlsWantBadBoys: Yin seems to fall instantly for anyone she knows, if they become tainted with evil. Even Coop the chicken. [[EspeciallyZoidberg Especially Coop the chicken.]] It becomes very plot relevant in "Gone-a-Fowl."
40	* AlliterativeTitle: To achieve this, the writers added Yo to [[AlliterativeFamily the show's name]], though he has much less importance to the show than the first two.
41	* AlphabeticalThemeNaming: '''Y'''in, '''Y'''ang, '''Y'''o.
42	* AmazingTechnicolorWildlife: Needless to say, few of the animal character have colors resembling their real life inspirations.
43	* AmbiguouslyGay: 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.
44	** Granted, in one episode, he mentions once having been spurned by a girl (or "jezebel" as he called her) due to still living with his mother, so he could be just CampStraight.
45	* AndNowYouMustMarryMe: A non-villainous example in "For The Love of Clamboy". Yin accepts a massive jewel from the friendly but very goofy Clamuel, agreeing to be his "super special friend" and to attend to the Clam Ceremony with him. She misinterprets the event as being some sort of dance/coming of age ritual when in reality her materialism paved the way to his tradition's equivalent to accepting a marriage proposal.
46	* AnimationBump: A subtle but noticeable one in season two.
47	* AnimalBattleAura: A Woo Foo Aura, which is in the shape of the animal that makes it.
48	* AnimalsNotToScale: Master Yo, a panda, is appropriately much bigger than his rabbit pupils who are considerably smaller than most of the cast with a few exceptions. For example, Coop the chicken is especially tall while Lina, a dog, is only a few inches taller than her own boyfriend. But this namely applies to the bug characters Carl the Evil Cockroach Wizard and Herman who are very large given their species, being just about a head shorter than Yin and Yang. Also for a tiger, Ella Mental is downright tiny.
49	* AnimatedActors: Used prominently in "A Walk in The Woods" where Yin and Yang are shown commenting on the show's events via the comfort of a trailer baring the show's logo. "An Inconvenient Tooth" also concludes with the twins speaking directly to the audience.
50	--> '''Yin''': Hi, we're TV's Yin and Yang! You might know us from the program you just watched and the made for TV movie, ''Tears of a Dove''.
51	* AppealToTradition: ''Division Quest'' had Indestructo-Bob beat up the King of Redneckistan, and due to tradition [[AuthorityEqualsAsskicking he's now king]]. When Jobeaux and Yin show up to face him, Jobeaux is forbidden from using Woo Foo or getting help from Yin, since it's against tradition. Jobeaux decides that he does love his family, home and traditions, but having undergone CharacterDevelopment, he reckons that tradition is not worth it if it puts an idiot like Bob in charge. His RousingSpeech leads the rest of Redneckistan to do the same.
52	* ArtifactOfDoom: Ironically, most of the power items are in Yo's Woo Foo Armory, but the villains get their hands on it and HilarityEnsues.
53	* ArtisticLicenseBiology: 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. Then there's the recurring feature of floating ears being more of a stylistic choice. "A Walk In the Woods" even acknowledges this:
54	--> '''Master Yo''': I'm looking for a couple of children: lazy, pink and blue, [[LampshadeHanging ears ain't attached to their heads... no tails.]]
55	** This is played for drama in "Yin Yang You". Yin, Yang, Lina, and Carl are trapped inside the real world which slowly causes them to change into anatomically correct animals. Even before their transformation, the humans cannot hear them talk. To all four of them, this is... less than good. To different degrees:
56	*** Yin and Yang are upset, since they have trouble controlling their "hoppy" legs and can't hold things with their paws.
57	*** Lina is mainly just annoyed, because "talk to the paw" is a terrible CatchPhrase.
58	*** Carl is grossed out over becoming a real cockroach, but is too distracted by his latest scheme to pay it too much mind.
59	* ArtShift: Yuck's flashback in "Upstanding Yuck" is illustrated like a children's crayon drawing.
60	* BadFuture: 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 ResetButton on it. [[spoiler:When Yang use this as a advantage to get back at others for his miserable day, 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 that future from happening by hitting the ResetButton once more on it and being nice this time around and stopped Ultimoose, [[spoiler:with the help of the other villains who Yang was nice to!]]
61	* BadassAdorable: The titular Yin and Yang are two cute rabbit twins who defend the city from evil. They're noticeably smaller than most of their foes but hold their own in a fight plenty well, especially when they work together.
62	* BadassFamily: [[spoiler: The titular trio turn out to be one as of the finale.]]
63	** Brother Herman and Carl, when they work together.
64	* BadassTeacher: Master Yo, whenever he actually joins the battle.
65	* BalloonBelly:
66	** Happens to Yin in "How the Cookie Crumbles" after she ate a lot of boxes of cereal and she even has [[ExposedAnimalBellybutton her umbilicus exposed]].
67	** Yang also gets one after winning an eating contest against Roger Jr. in the episode "Skirting the Issue".
68	* BattleCry: Quite a few in particular.
69	** Yang: "Chee, Hoo, Wha!"
70	** "I said 'Chee-hoo-wha', not 'Chihuahua'!"
71	** Ultimoose: "HOOH! HAH! HOOH!"
72	* BarefootCartoonAnimal: Quite a few characters go around without shoes, particularly the main three.
73	* BeCarefulWhatYouWishFor: While the official {{Aesop}} of ''Mission Yin-possible'' is "don't jump to conclusions," this trope easily qualifies as a secondary Aesop: the ArtifactOfDoom du jour, the Fuzzy Pink Slippers of Heart's Desire, will grant you your [[ExactlyWhatItSaysOnTheTin heart's desire]], [[WantingIsBetterThanHaving but they will be bound to you by magic and can't be removed until you no longer want what the Slippers gave you.]]
74	* {{Bedheaditis}}: In "Woo Foo Flu", the titular illness gives Yin messy fur.
75	* {{BFS}}: Smoke's sword which is nearly as large as she is.
76	* BigBad:
77	** The Night Master in season one until he’s defeated in “Night Fall”. Eradictus then takes his place in season two.
78	** Ferocitus appears in the last episode of season two and seems as though he would have filled the slot for the past villains.
79	* BigBallOfViolence: An inevitble part of Yin and Yang's arguments ends with them ending up in one of these. They normally end up untangling themselves to address a bigger threat or from Master Yo intervening.
80	* BigWhat: Yin and Yang's reaction to learning that [[spoiler: Master Yo is their biological father.]]
81	* BlahBlahBlah:
82	--> '''Yang''': I chop! I smash! I-
83	--> '''Yin''': Blah, blah, blah.
84	* BookDumb: 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.
85	** He actually lampshades that he does keep standards low so he gets away with more. See ObfuscatingStupidity.
86	* BracesOfOrthodonticOverkill: Due to his poor dental hygiene which results in him getting Wild Hare Tooth, Yang ends "An Inconvenient Tooth" wearing one of these much to his embarrassment.
87	* BrainsAndBrawn: 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 ObfuscatingStupidity.
88	* BrainwashedAndCrazy: [[spoiler: Yin is subjected to this multiple times by Coop using his Nightmaster energy on her to make her like him. It goes so far that it not only alters her physical appearance but turns her completely evil to the point she would have been the new Nightmaster if she had done the most evil deed possible: killing her brother.]]
89	* BrickJoke: 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 [[PungeonMaster a baby chicken.]] The last episode of the series has ULTIMOOSE [[spoiler:honestly attracting Coop's mom.]]
90	* BrotherSisterTeam: The titular bunnies.
91	* ButtMonkey:
92	** Yang, obviously.
93	** 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.
94	** Carl and Ultimoose are often shunned and mocked by other villains due to their idiocy.
95	* CaptureBalls: Smoke and her brother Mirrors are anime-esque villains who use magical prisms to capture anyone they throw them at. The Woo Foo siblings were captured by those characters for a battle against each other.
96	* CatchPhrase:
97	** Yang: "Hippity hoppity hard", "That's right!", "Pellets!" and "Two words. 'Who' 'Cares'?"
98	** Lina: "Talk to the hand!"
99	** 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."
100	* CallingYourAttacks: "Yincinerate! Yangarang! Transfoomate!" et. al.
101	* CanisLatinicus: "Roboticus Maximus" translates to Biggest/Important Robot.
102	* CardCarryingVillain: Nearly every villain in the series addresses themselves as evil but mostly "Carl, The Evil Cockroach Wizard!"
103	* ChainedHeat: Happens to Yang and Carl that kicks off the plot to "Get Off My Back".
104	* ChristmasEpisode: "Seasons Beatings" in which Zarnot assembles an army of evil toys to destroy Yin and Yang during a Woo Foo holiday equivalent to Christmas. The episode is even subjected to a rhyming narrative here and there.
105	* ChuckCunninghamSyndrome: Molecu-Lars, one of Eradicus' mooks had an unexplained disappearance after his first appearance.
106	* ClownSchool: A fighting variation appears here as Yin and Yang spend the episode learning Clown Foo, a martial arts based on clowning around: Yo was a former practitioner and Yang excels at it. However, the techniques do not work on humorless foes (here, the accountants) resulting in the kids using their Woo Foo to defeat said accountants.
107	* ComicallyMissingThePoint: Yang has an ongoing habit of doing this in response to Yin’s panic during a bad situation.
108	* ConfidenceBuildingScheme: The climax of "The Confidence Game" has [[spoiler: Master Yo pretending to die so Yin and Yang can regain their confidence after nearly dying in multiple one-sided fights against Eradicus' minions.]]
109	* CouchGag: After the title from the intro sequence comes a random line from the episode, often one that sounds wrong or awkward out of context.
110	* {{Countrystan}}: There's a country called Redneckistan, which -- as the name indicates -- is full of DeepSouth stereotypes.
111	* CoveredInMud: 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.
112	--> '''Yin''': Mud? I don't land in mud!
113	* CreepyDoll: 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.
114	* CryingARiver: In the first episode, Yin goes home crying after Yang stays at the gym without her. Later in the episode, she ends up flooding the dojo with tears.
115	* CrystalBall: Saranoia and Carl both have these to spy on the twins occasionally.
116	* CueTheFlyingPigs: After Yin manages to get a date, a [[LiteralMetaphor pig sprouts wings and flies off]].
117	--> '''Yang:''' YouHaveGotToBeKiddingMe
118	** Gets a BrickJoke alter on, when [[spoiler: it turns out that the boyfriend is Yuck, he points to a real pig without wings to indicate that Yin could never get a date]].
119	* CuteBruiser: Being pink and blue bunnies, both twins do qualify.
120	* CutenessOverload: Yin quite literally weaponizes her own cuteness against the giant hot dog monster feeding off the fear of the town's residents after seeing it cower in fear at the sight of a puppy. This ends up giving her some solidarity as she was insecure about her own cuteness making her already unscary Weenie Howl costumes even less scary.
121	* DarkActionGirl: Saranoia, Smoke, and Ella Mental.
122	* DeadpanSnarker:
123	** Lina, Ella Mental, and G.P.(Fr-ped), specially toward Saranoia the latter.
124	** Carl can be ''very'' snarky towards his mother.
125	--> '''Edna:''' Try not to embarrass me.
126	--> '''Carl:''' Well, it'll be hard to compete with ''that'' gown.
127	* DeflectorShields: Foo Field is able to deflect off most physical attacks.
128	* DeliberateValuesDissonance: One episode has the heroes get transported into an old move similar to ''Film/KingKong1933''. They're quick to mock the [[HollywoodNatives outdated portrayal of the natives]].
129	* DepartmentOfRedundancyDepartment: "Power doesn't make you evil. Being evil makes you evil!"
130	* DisproportionateRetribution: Yuck tends to do this a lot.
131	** 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.
132	*** Also in "Yin Yang Yuck!", when Master Yo refuses to train Yuck, Yuck responds by trying to kill him.
133	** 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 [[ControlFreak "You'll do what l say!"]]
134	** In a non-Yuck example, Ranger Ron is convinced bears are heathens who need to be destroyed because one stepped on his feet accidentally at the cinemas.
135	* DoesThisRemindYouOfAnything: Amongst many edgy jokes in “Fighting Fooberty”, Yang’s jittery, eager response to Lina is incredibly similar to a boy experiencing arousal.
136	* DoomyDoomsOfDoom: Carl and other villains tend to do this a lot.
137	* DragonsUpTheYinYang: No pun intended, but season 2’s BigBad Eradicus is a dragon.
138	* DramaticDrop: Yo, on the occasion of realizing his students are about to let SealedEvilInACan out.
139	* DramaticThunder: Used at the end of "Upstanding Yuck" when Yuck [[spoiler: becomes evil again.]]
140	-->'''Yuck''': You wanted me to [[spoiler: be evil again? Ha! I'm evil again!]] (cue lightning) [[LampshadeHanging And there's the lightning to prove it]].
141	* DumbMuscle: Indesructo-Bob, emphasis on ''dumb''.
142	** Ultimoose is also this, though he at least can come up with plans sometimes.
143	* EatingTheEyeCandy: Yin and Lina throughout the entire duration of "Size Matters" as they attend a Beef Cake Convention just to ogle muscular men.
144	* TheEndOfTheWorldAsWeKnowIt: "Woofoogeddon" and to a lesser extent, "The Dark Tomorrow".
145	* EvenBadMenLoveTheirMamas: Both Carl and Herman love Edna and try to impress her through their evil deeds.
146	* EvilCounterpart: Yuck who was created accidentally by Yin and Yang's bad qualities such as Yin's obsession with control and Yang's aggression. Even so, he tries to subvert this in Upstanding Yuck. [[spoiler: He fails...]]
147	* EvilIsHammy: The villain characters are far less understated than the heroes.
148	* EvilLaugh: Most of the villains have one.
149	* EvilRedhead: Smoke and Ella Mental both have red hair.
150	* EvilSorcerer: Carl The Evil Cockroach Wizard, [[SpellMyNameWithAThe which he's quick to remind people about]], is a self-taught sorcerer with borderline RealityWarper powers if he's feeling especially creative. He namely uses his abilities to curse things but can also devise energy blasts, fly/levitate, and teleport.
151	** The Night Master is also a sorcerer, albeit more competent. His arrange of powers is mostly rooted around [[CastingAShadow using shadows]] but in broad daylight, [[WeakenedByTheLight his one true weakness,]] he'll send his minions or get by on sheer manipulation.
152	** Saranoia is the most recurring female example, having studied magic sense childhood. Her skills come in the form of various wands that can alter her powers and appearance.
153	* EvilTastesGood:
154	** In "Dance Dance Devastation", Carl buys ingredients for his evil cookie: when he comes across evil butter, he licks it and says it's [[{{Crunchtastic}} "evil-licious"]].
155	** When Yin hides inside of a cheese cake in "Mission Yinpossible", she comments that it's "evilly rich".
156	* EvilerThanThou: Played for laughs between Carl and his brother Herman.
157	* ExposedAnimalBellybutton: Yin, Yang and Yo all have one. However, Yin and Yang's can only be seen in a few episodes whenever their shirts lift up. It is also interesting that Master Yo has an innie but Yin and Yang have outies.
158	* EyeScream: In "This Yang Isn't Brought To You By", a toy that Yang advertises called "Eye-Biters" is a pair of glasses that sprout miniature bear traps and crush the wearer's eyes.
159	* EyedScreen: Another trope used to emphasize the show's spoofing of martial arts films.
160	* FacialMarkings: A common trademark of current The Nightmaster is the spiked red mark spreading across his eyes. [[spoiler: When Yin becomes fully corrupted to the point she's one step away from becoming The Night Mistress, she gets a similar one albeit black.]]
161	** Ella Mental has a small star and moon marking on her cheeks.
162	* FakingTheDead: [[spoiler: In an attempt to get Yin and Yang to stop being so dependent on him, Master Yo pretends to be killed by Eradicus by what was otherwise an attack so weak it was practically harmless. He even keeps the schtick for a while.]]
163	* FantasticSlur: At times the villains will address those who use Woo Foo, particularly Yin and Yang, by the term "Woo Fools".
164	* FantasticVoyagePlot: The focus of the episode "Voyage to the Center of the Yo"
165	* FantasyKitchenSink: The core plot itself centers on Taoist teachings with the world having very East Asian inspired architecture in a clearly magical setting populated by monsters, animals, and vaguely humanoid creatures. There's just as many blends of modern and futuristic technology like anything in the Woo Foo Armory (the battle cruiser, an entire rocket ship) and the antagonists range from wizards and witches to evil robots and anime parodies, all the while centering around things like magically charged artifacts that date back to possibly centuries ago.
166	* FatteningTheVictim: An old witch fattens Yin and Yang up with a big strawberry cake in the episode "A Walk in the Woods".
167	* FirstKiss: Yin hopes to have this in "Falling Yin Love". Yin really grows to like Brett and the two of them do kiss in the end. [[spoiler: It's revealed to be Yuck and Yin's kiss provided him with enough power to regain his physical form.]]
168	* FlashyTeleportation: Foopertation is a fairly common Woo Foo move on the magic side of things. The user is always encased in a large ball of light with a colored silhouette in the middle with the same effect appearing once they've reached their destination.
169	* FlyingBroomstick: Parodied in "Camp Magic Pants," being a Harry Potter spoof after all.
170	* FootsieUnderTheTable: 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:
171	--> '''Yang''': Oh my gosh, Yin!
172	--> '''Lina''': No, it's Lina. You didn't think you were playing footsies with your sister, because that is weird.
173	* FountainOfYouth: Kraggler has this power, using it mostly on himself, but one time on Master Yo.
174	* FourFingeredHands: Every character has four fingers which makes The Manotaur's five fingers seem like the equivalent of BodyHorror to everyone else.
175	* FreeRangeChildren: Yin and Yang are at least between the ages of 11-12, normally identified as tweens by the narrative, but spend a good majority of their off time exploring the city, going to the mall, the movies, restaurants, and even going on errands alone on Master Yo's request. Partially justified in that they're the town's designated town heroes and are probably just keeping an eye out for any trouble as part of their training but even their non superpowered friends are seen wandering out in the open without their parents.
176	* FreudianTrio: Yang is the Id due to his rash impulsiveness and ObfuscatingStupidity, while Yin, being the more calculating and pragmatic one of the two, is the Superego. The Ego spot is normally filled by [[TheMentor Master Yo]], [[OnlySaneWoman Lina]] or [[TheChewToy Dave]].
177	* FunWithAcronyms: 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".
178	* FooFu: The titular martial arts style Woo Foo, a near extinct practice of mystical kung-fu.
179	* FurryReminder: Though not always as the predominately animal cast is fairly humanoid, there are a few subtle elements of this.
180	** During "Mission Yin-Possible", Yin states that her and Yang could get over the lasers protecting a building they need to get into by jumping. Yang looks at her with a confused expression before bluntly reminding them that their rabbits.
181	** When Yang deliberately tries to annoy Yin on a road trip, he loudly slurps from [[GiganticGulp a giant soda]] but immediately regrets his decision after Yin reminds him that the average rabbit bladder can only hold six ounces of fluid. Cue the PottyEmergency.
182	** The entirety of "Splitting Hares" has Herman's ant army going out of their way to collect sugary treats in between fetching ingredients for a potion.
183	** Yin and Yang's ears can be rather expressive when frightened, alert, happy, or sad.
184	** "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.
185	* GoodAngelBadAngel:
186	** Yang has this in "Deja Foo".
187	** Yuck sort of has one in "Personality Problem": the difference being is that he has a girl half and a boy half and they're both evil. Yuck shows discomfort and anger at having a female half.
188	* GrandTheftMe: After Yang is tricked into signing a coupon given to him by Mastermind, he has his brain yanked from his body, allowing Mastermind to possess him and use it to wreak future havoc on the world. He luckily never gets as far as teroizing the dojo as Yang is able to destroy the coupon before sundown and get his body back.
189	* GranolaGirl: Yin has shades of this.
190	* GratuitousForeignLanguage: In "Dance Dance Devastation", Yin and Yang briefly sing in GratuitousSpanish...then GratuitousGerman on Carl's command.
191	* GrievousHarmWithABody: [[spoiler: When Yin and Yang push Yuck past his limit during the unveiling of a giant friendship monument towards the end of "Upstanding Yuck", Yuck punches Yang into the air only to grab him again without even looking and then throwing Yang's body at Yin's.]]
192	* GroinAttack: In 'Gone-A-Fowl', Boopy Von Ha-Ha Pants kicks Master Yo in the head multiple times, then in the crotch.
193	* GrossOutShow: There’s plenty of belching, farting, and a few poop jokes here and there.
194	* GrossUpCloseUp: When Carl turns the twins ugly in "A Bad Case of the Buglies".
195	* GuysSmashGirlsShoot: The tactical difference between Yin and Yang.
196	* HalfDressedCartoonAnimal: A good portion of the characters go about in only a shirt, a belt, or some form of accessory as an outfit. There is a still amount of background or side characters who wear a full set of clothing.
197	* HalloweenEpisode: "The Howl of The Weenie" serves as this.
198	* HammerSpace: All of the characters seem to have this but especially Yang who can pull out his sword at any time.
199	* HarmlessVillain: Varies constantly with Carl: on one hand, he’s an incredibly flamboyant cockroach wizard who still lives with his mother and feels the need to remind people that he’s evil; but, when provoked, he can do a fair amount of damage with his magic.
200	* HeartSymbol: 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.
201	* HeelFaceRevolvingDoor:
202	** [[spoiler: In the episode "Upstanding Yuck", Yuck was beaten up by a group to become good and then became evil again when he got beaten up by Yin and Yang one too many only to realize that he was [[GoodAllAlong good all along]].]]
203	** In the episode "Crawling with the Enemy", a disguised Carl [[EnemyMine teams up with Yin and Yang]] to take down one of Eradicus' corporations. 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.
204	* HerCodeNameWasMarySue: Yang wrote a lot of stories about being a superhero in a world he made up (when he was four) [[OldShame and is mortified when Yin discovers them]].
205	* HoistByHisOwnPetard: Yang even {{Lampshades}} it.
206	--> '''Yang''': Our enemies usually end up defeating themselves.
207	* HomeschooledKids: Both Yin and Yang are of age to at least be in middle school but are taught by Master Yo the academic and physical aspects of Woo Foo. Could be justified, given that Woo Foo is treated as a joke by the community and schools wouldn't be considered necessary to begin with.
208	* HumongousMecha:
209	** Zarnot is a living toy robot but can become large if needed.
210	** In "Smorks", the Smorks create a giant Smork Bot out of multiple electronics from the dojo.
211	* HypocriticalHeartwarming: Yin says (on multiple occasions) that she's the only one who gets to laugh at Yang.
212	[[/folder]]
213
214	[[folder:Tropes I - P]]
215	* IAmBigBoned: Master Yo attemtps to do this when he is reduced to bones at one point, though it's clear it isn't the case when his flesh and fur comes back.
216	* IKissYourHand: This is used as a sneak tactic to remove the Fooplication Charm from someone’s wrist and hide it in the mouth during "Imperfect Fooplicates".
217	* IResembleThatRemark: Episodes like Turn About and Unmoving Pictures ring a bell when it comes to the protagonists.
218	* IfYoureSoEvilEatThisKitten: In order to get access to the Night Master's lair and get the title, you must commit very evil acts. [[spoiler:Yin would have become the Night Mistress if she crosses the MoralEventHorizon by [[ShootYourMate killing her brother Yang.]]]]
219	* IllnessBlanket: Yin is wrapped in one on the title card for "Woo Foo Flu." Averted in the episode proper, though, since she sends most of her time in bed.
220	* IncestSubtext: Some moments between Yin and Yang invoke this trope.
221	** "I don't have to listen to you, you're not hot anymore."
222	* {{Invisibility}}: Well, [[CallingYourAttacks Yinvisibility and Yangvisibility]].
223	* InvoluntaryDance:
224	** In "Dance Dance Devastation", Carl puts a spell on the dance game Yin and Yang are playing that forces them to dance and sometimes sing against their will: if they don't, a monkey that keeps following them zaps the two; they later use this to their advantage and become {{Dance Battler}}s.
225	** Yin and Yang beat Yuck in "Camp Magic Pants" by making the gold pants dance with disco music and disobey him.
226	-->'''Yang''': Silly Yuck, don't you know: everyone's pants love disco.
227	** Utilized by the Parachute Pants of Punishment, a pair of one size fits all golden pants that make one dance like MC Hammer. After accidentally ruining the Skirt of Ultimate Protection, Yang is forced into said pants and begins dancing embarrassingly against his will.
228	* {{Irony}}: In "Who Knows What Evil Lurks", Yin and Yang travel through time to find out who's the Night Master's spy. During their travels, they noticed Coop was around frequently. They just laugh at the idea that he could be the spy. By the end of the episode, Yin and Yang decide the identity of the spy is unimportant since they'll defeat the Night Master anyway. Come the next episode, Coop reveals himself to be the spy.
229	* ITakeOffenseToThatLastOne: When Yin and Yang get told to leave a fast food drive thru because they don't have cars, the employee who has dealt with them before describes them as "a moron rabbit and his know-it-all sister". Yang's only gripe is calling Yin a know-it-all.
230	* {{Jerkass}}:
231	** Yang is often called one due to his immaturity and selfish nature during certain moments, but he does show he can be fairly [[JerkWithAHeartOfGold nice after learning a lesson]].
232	** Master Yo can act this way mainly due to being a grumpy old man and lacking patience when it comes to teachings. But much like Yang, he has a soft spot.
233	** Yuck is called this constantly due to being made of negativity and receiving Yang’s often brash, violent behavior.
234	* JokerJury: Used in "Fit To Be Tried". See KangarooCourt for more details.
235	* JumpingOutOfACake: A lighthearted example, being that Yin does so in Mission Yinpossible.
236	* KangarooCourt: One episode has Carl try to make it seem like Yin and Yang are guilty of misusing Woo-Fu for evil. But even with the jury being made up of Brother Herman’s Mooks and the witnesses being members of the RoguesGallery, it only succeeds up the point where Master Yo, acting as the defense lawyer, tricks Carl into an EngineeredPublicConfession (in spite of Saranoia claiming Yin is innocent, because the girl is never guilty and Kraggler falling asleep and forgetting his testimony). And then they go to jail anyway for wrecking the courtroom.
237	-->'''Yang:''' I’ve got two words for you: electric chair.
238	* KiManipulation: Though it's never called chi/ki, Woo Foo is treated like its own energy source and can be embedded in mystical artifacts and freely manipulated by the user. This is namely in the form of magic as best demonstrated by Yin and Master Yo who can levitate, move objects, and transform things on a whim.
239	* KidAnova: Yang tries to be this to Lina. Key word [[CasanovaWannabe tries]].
240	* KidHero: Yin and Yang along with about every member of the Woo Foo Army by the end of the second season. It’s never directly stated how old they are but it's implied to be around eleven to twelve years old.
241	* KneelBeforeZod: In "Welcome To The Dark Tommorow", Eradicus uses the Licking Stick to force Yin, Yang, and Yo into bowing before him.
242	* LampshadeHanging: One of the primary sources of humor on the show.
243	* LargeHam:
244	** Yang has his moments of being especially dramatic and energetic during his rants or fits of excitement.
245	** [[EvilIsHammy All the recurring villains are large hams.]]
246	* LastMinuteHookup: Kinda. It's in one of the final episodes though it has been teased for awhile beforehand for [[spoiler:Yin and Coop]]
247	* LastOfHisKind: Master Yo is quite fond of telling anyone who will listen that he is the last panda on the planet. Before training Yin and Yang, he was also the last Woo Foo warrior.
248	* LetsGetDangerous: Carl, when he [[spoiler: was wiping the floor with Night Master's EliteMooks in the Season 1 finale.]]
249	* LuckyRabbitsFoot: In "Family Day", Carl and Herman's mother, Edna, decides that she wants a pink and a blue rabbit's foot to complete her collection for the titular holiday, and Yin and Yang happen to be pink and blue rabbits, respectively. It's only because of Carl and Herman's poor teamwork that they end up failing.
250	* LukeIAmYourFather: [[spoiler: Yo is Yin and Yang's father but was forced to forget they even existed so that he could train them to their full potential without any parental bias.]]
251	* MagicIsFeminine: Yin is the sole magic user between the twins which Yang specifically mocks for being too girly of an art form to be worth his time. Over the series, he does learn ways to minorly utilize magic into his fighting style and it's shown that any Woo Foo warrior worth their salt have to be versatile in both Might and Magic.
252	* MagicWand: In "Camp Magic Pants", along with {{Flying Broomstick}}s, those attending the camp are given magic wands.
253	** Saranoia has an arsenal of these that come in the form of various items that transform into whatever for she needs to (the broom wand makes her look like a maid and having cleaning-based powers while a lipstick wand makes her into a popular tween.) It also transforms her gnome minion, Fred.
254	* MaliciousMisnaming: Saranoia does this to Yang every time she appears on the show, giving him the nickname “Mark”.
255	* ManipulativeBastard:
256	** [[spoiler:Yuck]] uses Yin twice for his own gain:
257	*** In "Falling Yin Love" he poses as her dream boy and dates her while the whole time he is actually [[spoiler: absorbing her Woo Foo to regain his physical form.]]
258	*** In "Camp Magic Pants" he [[spoiler: possess the headmaster and manages to make Yin become evil so she can touch the golden pants and allow him to control it.]]
259	** The biggest example was [[spoiler: Yang having manipulated by Eradicus' minions, who posed as Woo Foo Elder spirits for several episodes. They tricked him into gathering several Woofoo items supposedly to stop "The Dark Tomorrow." Turns out the items were used to bring back their boss and bring about the event.]]
260	* MediumAwareness: Prominent in Season 2. Characters will acknowledge flash backs, physically interact with scene transitions, or even comment on a past adventure being "an episode".
261	* MinorLivingAlone: [[spoiler: After the events of "The Confidence Game" where Master Yo [[FakingTheDead fakes his death]], Yin and Yang spend the long stretch of season two living by themselves.]]
262	* MisfortuneCookie: Jealous of Yang's streak of good luck, Yin buys a pack of these from a (disguised) Carl which causes Yang a multitude of random misfortunes when they visit a carnival.
263	* MommasBoy: Herman, oh so much. It’s why Carl can’t stand him.
264	* {{Mooning}}: Yang does at the end of "The Yindianapolis 500" to President Muffin, despite the fact that he doesn't even wear pants.
265	* MorphWeapon: Yang can change his sword into a staff, nun-chucks, a jam hammer, and fruit.
266	* MusclesAreMeaningless: Yin and Yang are two very tiny children in size and stature but they're more than capable of beating the likes of the more obviously bulky villains like Ultimoose. This is even a plot point in "Size Matters" where Yang becomes incredibly insecure about his own lack of obvious muscle, making him forget the fact that he's still a PintSizedPowerhouse.
267	* MyBelovedSmother: It's made obvious that Herman relishes his mother's doting, but when Carl briefly gets his mother's undivided love and attention in ''Mission Yin-possible'', he finds that being the favorite entails a lot more babying than he is comfortable with.
268	* NeverSayDie:
269	** The word "destroy" is a common replacement for the villains though “die” is often used during more serious moments.
270	--> '''Master Yo''': You could have been killed!
271	** There's also in "Yin Yang Who?" [[spoiler: after Yin jumps in front of a Woo Foo Aura Drain, she's aware that she'll die soon.]]
272	--> '''Yin''': [[spoiler: That was the Aura Drain and now I'm gonna d...di...]]
273	--> '''Yang''': [[ComicallyMissingThePoint Dance?]] Oh great, and now I'm gonna yack. Bucket!
274	** And in "Attack of the Vidiots" when The Lesson tries to destroy the game that Yang is inside in.
275	--> '''Yin''': Whoa whoa whoa! If you break the game while he's inside it, he'll totally '''die''' or something!
276	* NewPowersAsThePlotDemands: Lampshaded in ''Dojo Alone'' after Yin and Yang finally combine their Auras.
277	--> '''Yin and Yang:''' [[CallingYourAttacks Fists of Yincineration]]! Which we suddenly know we can do!
278	* NiceToTheWaiter: The inciting incident of "Extra Cheese, Anchovies and Doom!" is Yin and Yang thinking lowly of a pizza delivery man which results in them being roped into doing his entire route for him as a way to apologize. The twins learn their lesson at the end as they realize just how legitimately dangerous being a pizza man really is.
279	* NoCelebritiesWereHarmed:
280	** Averted - Nancy O. Delffa (and voiced by none other than Nancy O'Dell herself)
281	** G.P. sounds like Creator/NormMacDonald.
282	* NonStandardCharacterDesign: The clams in "For The Love of Clamboy" seem to have actual photos of clams in their design.
283	* NotSoHarmlessVillain: Carl in season one finale[[spoiler: even though he was helping the good guys]]. Lampshaded by the twins. When Yin questions if he always that capable, Yang answers yes, but they keep throwing him off through the use of insults.
284	* NotQuiteFlight: A common Woo Foo ability is being able to freely levitate though Yin and Master Yo are never seen outright flying. We see with Yang that they can also jump high distances and survive some otherwise brutal descents.
285	* ObfuscatingStupidity: Yang is actually smarter than he looks. He just keeps everyone's standards of him low so he gets away with more.
286	* ObsessedAreTheListMakers: In "Slumber Party of Doom", Yin creates an incredibly long list of what she feels is necessary to throw the perfect sleepover that must be performed at specific times. Her friends are quite annoyed by this.
287	--> '''Yin''': Some say I'm obsessive, I say I'm a well oiled fun machine!
288	--> '''Lina''': I say obsessive.
289	* OcularGushers: In the first episode of the show, "Dojo, Oh No!", Yin does this at one point after Yang becomes a member of Ultimoose's dojo, so much that it floods the entire room. Carl also does this at the end of "Too Much Yangformation" after being yelled at by his mother.
290	* OfficialCouple:
291	** [[spoiler:Yang and Lina.]]
292	** [[spoiler:Yin and Coop.]]
293	* PaperThinDisguise:
294	** Done by Carl often and Yin and Yang always seem to fall for it.
295	** In "Mission Yinpossible", Yang only wears a mustache and Carl still couldn't recognize him.
296	** This is averted by Yuck who disguises himself so well not even the viewer know it's him until the ending. These "disguises" involving [[spoiler: controlling robot suits and even body possession.]]
297	** Averted again this time by [[spoiler: Badfoot]] who wears two convincing disguises in "Old Softie".
298	* ParentalAbandonment: Yin and Yang's parents have not made an appearance so far with Master Yo being their only parental figure.
299	** [[spoiler: Yo is somehow their father, but forced to forget by Chai and Ti when they were born. The [[MissingMom identity of their mother is still a mystery, though]].]]
300	* ParentalBonus: "League of Evil" has a few references to [[Series/Batman1966 the 60s Batman show]]. They even have an announcer.
301	* ParentalFavoritism:
302	** Saranoia's FreudianExcuse is that her wizard father adored his son and paid little attention her while growing up.
303	** Edna doesn't bother to hide that she prefers Herman over Carl.
304	* PinPullingTeeth: Yuck bites off the pin of a coconut shaped grenade and throws it at Yin and Yang in "Voyage To The Center of Yo".
305	* PinkGirlBlueBoy: Yin and Yang, respectively.
306	* PintSizedPowerHouse: Yin, Yang, Lina, and practically every member of the Woo Foo army, composed entirely by (insanely strong) kids.
307	* PlotRelevantAgeUp: Kraggler does this to Yin and Yang in his debut episode, taking advantage of the twins' desire to become older so they can see a mature film. Though they start off old enough to do just that, they also ''keep'' aging.
308	* PolarOppositeTwins: Yin and Yang. The former is more responsible and favors mystical power, the latter is BrilliantButLazy, with a love for physical fighting.
309	* PowerGlows: Woo Foo can be transferred into weapons, making them glow an often yellow color when especially powerful.
310	* PowerNullifier: The Woo Foo Aura Drain is able to drain any Woo Foo powered user of their powers as well as causing them to slowly die unless they come in contact with either of their parents to save them: [[spoiler: Yin has this done to her by Eradicus in an attempt to save her brother. She is saved by Master Yo.]]
311	* PowerTrio: Master Yo, Yin and Yang, as well as the Chung Pow Kitties.
312	* ProtagonistTitle: The three main protagonists are called Yin, Yang, and Yo.
313	* PsychicPowers: One of Eradicus minions Ella Mental has a broad range of telepathic powers. Her main crutch is mind reading but she can also hypnotize people and move around objects freely.
314	** The mystical side of Woo Foo allows this as well. Yin especially demonstrates the ability to levitate and even transform objects with sheer mental power. It's Yang's lack of mental strength that makes it difficult for him to even muster psychic energy and he's forced to channel his hidden magic potential in "Brain Drain".
315	* PsychologicalProjection: Saranoia constantly projects her own childhood traumas onto Yin and thinks taking in (i.e. abducting) Yin will somehow fix her own broken relationship with a misogynistic father. It's too the point she constantly refers to Yang by her own brother's name, Mark.
316	* PungeonMaster: Almost every other sentence from Rubber Chucky is some sort of painfully awful pun. He'll even pause and wait for laughter if he doesn't [[DontExplainTheJoke immediately try to explain the joke.]]
317	[[/folder]]
318
319	[[folder:Tropes Q - Z]]
320	* QuirkyMinibossSquad:
321	** Eradicus' mook squad: [[PsychicPowers Ella Mental]], [[RubberMan Rubber Chucky]] and [[DumbMuscle Indestructi-Bob]].
322	** Molecu-Lars disappeared after their introduction.
323	* RealWorldEpisode: "Yin! Yang! You!" has the characters becoming real animals.
324	* ReformedButRejected: The general plot line of "Upstanding Yuck" practically revolves around this.
325	* RedOniBlueOni: Color-inverted. The pink furred Yin is more level-headed and relies more on magic in fight, when the blue furred Yang is brash and relies more on physical force.
326	* RedSkyTakeWarning: About anytime a villain appears and starts causing havoc, the sky turns red.
327	* RoguesGallery: Carl, Zarnot, Saranoia, Herman, Ultimoose... really, half of the cast is comprised of villains.
328	* ScaryStingingSwarm:
329	** Bees attack Yang in "How the Cookie Crumbles" and "Today You are a Bear"
330	** Lina gets attacked by them in "Zarnot's Girlfriend."
331	* SealedEvilInACan: Eradicus, [[spoiler: until Yang, [[NiceJobBreakingItHero in a misguided attempt to become famous, sets him free]], ushering in [[TheEndOfTheWorldAsWeKnowIt the Dark Tomorrow.]]]]
332	* ShadowDiscretionShot: Coop's first transformation into Evil!Coop has one.
333	* ShakeSomeoneObjectsFall: After [[spoiler: regressing back to his old ways and destroying the town with a blast big enough to be see seen from space,]] Yuck immediately teleports to the Redneckastanian orphan he donated money for and traps them in the grip of his magic to shake the money from their pockets.
334	* ShoeSizeAngst: In "Smoke and Mirrors", Yang's new girlfriend, who actually intends to enslave him and use him for her weirdly familiar competitions, is compared by his brother with a fat footed mammoth, which she denies claiming to be big-toed instead.
335	* ShouldntWeBeInSchoolRightNow: While Yin and Yang are [[HomeschooledKids homeschooled by Master Yo in the dojo]], their similarly aged tween friends are never seen attending school themselves, even if the town seems big enough to acquire more than a few. It can be implied that the twins only ever hang out with Lina, Dave, and Roger after school hours but there's no statement to certify it as true.
336	* SiblingRivalry:
337	** Yin and Yang, though they get along as often as they fight.
338	** Carl and Herman's rivalry borders CainAndAbel territory.
339	* SiblingYinYang: It's even in their names.
340	* SignatureHeadgear: Yin's go-to [[TertiarySexualCharacteristics that further distinguishes her from her brother]] is a small purple bow that supports her ears. She seems to have more than one too as on the rare occasions she's seen in a different outfit, she'll have a bow to match the ensemble.
341	* SickEpisode: "Woo Foo Flu" from start to finish.
342	* SkipOfInnocence: The now reformed Yuck exits the dojo with a joyous skip after promising Yin and Yang a surprise gift he has prepared during a ceremony the town is holding for all his good deeds.
343	* {{Slapstick}}: Though Yang receives a fair amount of slapstick, Yin and Lina tend to get hurt for the sake of laughs pretty often. The most prominent example is in “Splitting Hares” when Yin is shot off a cliff by Carl and breaks most of her bones on her way down a rocky hill.
344	* {{Smurfing}}: As a parody of Franchise/TheSmurfs, the Smorks do this constantly.
345	* SplitScreen: Used constantly in fights.
346	* StalkerWithACrush: 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.
347	* StealthPun: At an all-bear formal party, Yang asks where the bathroom is: a bear politely indicates the woods. Yang looks confused for a moment, then smacks his forehead and says, "Duh, of course."
348	* StacysMom: Coop's mother is incredibly attractive and is gawked over by anyone who meets her. During "Party Favors", in which she hosts a party to ensue [[spoiler: her son takes credit for defeating The Night Master when he actually didn't]] everyone is there just to look at her.
349	* StrawFeminist: Saranoia who is determined to take Yin away from her male teacher and brother because she’s convinced she's being abused.
350	* SugarBowl: The land of the Twonicorns is a massive field filled with rainbows, meadows, and enchanted forests. This provides a humorous contrast to the predominately male and clearly Italian residents that feel like a parody of this trope.
351	** Yuck attacks an even more literal version of this before the events of "Upstanding Yuck". Essentially a candy land that Yuck describes as the Candytopia of the Flippy-Dipple Gumdrop Fairies.
352	--> '''Yang''': Gumdrop fairies?
353	--> '''Yuck''': I know, that's why I was causing so much havoc!
354	* SuperpoweredEvilSide: Coop gets one after [[spoiler: ingesting the Night Master's powers]].
355	* SupernaturalMartialArts: Woo Foo utilizes a mixture of might and magic based techniques while having associated artifacts, traditions, events and even a ''sickness.''
356	* SwordAndSorcerer: Yang's Might and Yin’s Magic form the twins into this duo.
357	* TalkingWeapon: Yang's sword becomes sentient and capable of speech during the the season two finale. Its speech sounds mumbled and incomprehensible but Yang seems to be [[IntelligibleUnintelligible perfectly capable of understanding it.]]
358	* TertiarySexualCharacteristics: Yin's eyelashes and [[strike:hair]]earpin.
359	* ThemeTuneRap: Done by Kyle Massey of ''Series/ThatsSoRaven'' and ''Series/CoryInTheHouse'' fame.
360	* TitleDrop: Yin, Yang, and Yo say it as a battle cry in the Season One finale.
361	* TookALevelInBadass:
362	** Dave when he discovers his powers to manipulate plants.
363	** [[spoiler:Lina when she uses Might Woo Foo and was second-in-command of the Woo Foo army.]]
364	* TookALevelInJerkass: Later episodes of the second season have depicted the characters to be more obnoxious and rude than in past episodes, responding to each other in a very snarky manner, with the worst offenders being the twins themselves.
365	* TheToothHurts: A prominent example in "An Inconvenient Tooth" is about Yang catching Wild Hare Tooth from his extreme lack of dental hygiene.
366	* TornadoMove: The Foo-nado of course. Also the Yuck-i-cane which has a similar purpose and able to cause a fair amount of damage through high speeding winds.
367	* {{Transmutation}}: Transfoomate allows the user to change objects into pretty much anything they desire. This mostly extends to turning inanimate objects into something else entirely but can extend to living creatures like animals or even manifesting weapons.
368	* {{Tsundere}}: Lina, [[spoiler:she even [[LampshadeHanging lampshades]] this to Yang in "Gone-A-Fowl".]]
369	* TwinTelepathy:
370	** Yin and Yang occasionally hit the same thought at the same time and/or finish each other's sentences when they're separated and in danger.
371	** Yang has used it to find Yin on occasion, though not entirely under his own control.
372	* TwinkleSmile: When Yuck appears in "Upstanding Yuck", there are a few quick shots of his now clean self including one of his teeth sparkling.
373	* TheUnFavorite:
374	** Saranoia's rants indicate she was one of these growing up.
375	** Carl fits this trope even better than Saranoia, with his mother constantly praising his brother over him.
376	* UngratefulBastard: In "Who Knows What Evil Lurks", the Night Master berates Zarnot for his failure to destroy Yin and Yang. When Zarnot said that at least they haven't find out who's the spy, Coop (the spy) just punches him back into his toy box.
377	* UnusualEuphemism: "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".
378	* VerbalTic:
379	** Coop's habit of clucking in between his words.
380	** Rainbow Mane tends to say "and stuff" after his sentences.
381	* VillainTeamUp: The episode "League of Evil" has Carl, Smoke, Pondscum, and The Puffin form a team along with sharing an apartment together.
382	* VomitDiscretionShot: Used as a RunningGag in "Shadowcluck".
383	* WeaksauceWeakness:
384	** Carl is incredibly competent and dangerous when it comes to being a wizard, but enraging him makes him act like a six year old with a temper tantrum; this is shown in the season one finale, where Carl for once isn't fighting enemies who snark at him, allowing him to focus and take out hordes of opponents.
385	** Herman's allergic reaction to panda fur. There is exactly ''[[LastOfHisKind one]]'' panda left, but still.
386	* WellIntentionedExtremist: The grim reaper guardians of a candy land Yuck was terrorizing before the events of "Upstanding Yuck" are phrased this way. They remain completely anonymous entities but do run an "International House of Peaceful Readjustment" where their lessons include repeatedly beating Yuck until he stops being evil.
387	* WhamLine: [[spoiler: Master Yo tells Yin and Yang towards the end of "Yin Yang Who?" that he's their biological father. The episode, and by proxy the whole series, also concludes with Yin asking who their mother might be.]]
388	* WhereAreTheyNowEpilogue: Series finale "Yin Yang Who?" concludes with Yin and Yang narrating the events that happened after defeating Eradicus and the rise of the new Woo Foo army that handle lesser crime around town.
389	* WittyBanter: There's a small exchange in "Personality Problem" about this.
390	-->'''Yang''': So, should we start with some witty banter or just bring the pain?
391	-->'''Yuck''': Pain is good. Especially when I'm serving it-Ha! And I'm serving it up BIG TIME!
392	* WonderTwinPowers:
393	** The Woo Foo Aura results in a giant energy form made up of Yin and Yang working together so their BattleAura combines into a half-pink, half-blue Battle Bunny.
394	** Turned up a notch when Master Yo is also involved in it, his aura is green. Not surprising when you think about it.
395	* WoobieDestroyerOfWorlds:
396	** Yuck in "Upstanding Yuck".
397	** Carl can be seen in this way: it is implied on numerous occasions that his failed attempts at being a villain efficiently and the physical abuse of his older brother, is resentment that motivates him to try to defeat Yin and Yang to impress his mother.
398	* WouldHurtAChild: Yin and Yang are roughly eleven to twelve years old while all of their villains are implied to be adults or at least a good few years older than them. The only exception being Yuck who is their age and maybe a few one off villains.
399	* XtremeKoolLetterz: Pondscum is spelled as "Pondscüm".
400	* {{Yandere}}: Chad 3000 in "Moon Over My Yinnie" who Yin reprogramed to act like the ideal boyfriend. Though he starts off sweet, of somewhat goofy and smothering, he becomes incredibly possessive of Yin and tries to kill Yang multiple times.
401	* YouAndWhatArmy: When Yuck is accidentally resurrected from Yin and Yang's Fooplicates he steals the Fooplication Charm Bracelet and amasses an army of clones through duplicating the two that brought him back to life. When he confronts Yin and Yang, Yang mockingly asks him this trope only for rows and rows of clones to come rushing out. Yin and Yang blow through the first wave easily but are quickly overwhelmed at the sheer amount of duplicates Yuck has made while they were away.
402	* YouFool: Woo Fool seems to be a popular insult amongst the villains.
403	* YoungerThanTheyLook: In ''Size Matters'' Yin and Lina start ogling and giggling a big bodybuilder flexing for them. Before he continues after ripping off his shirt he states that he's fourteen and thus not being creepy showing off for the girls.
