Naruto recently introduced Killer Bee, who raps almost all of his prattle, even in the middle of battle. At one point, he actually says a different word from what he intended in order to keep a rhyme extended.
Bee: Noble beast, grab onto my arm, then I'll toss ya in the clock direction of ten.
Motoi: Don't sacrifice the truth for a rhyme, Bee! He went two o'clock!
Team Rocket speak almost entirely in rhymes and dated-but-still-catchy phrases. This is not to mention, of course, their Once an Episode recitation of the Team Rocket Motto, or their habit of stopping mid-action to sing songs based on popular tunes. This is likely meant as parody, however, as it seems to be an emphasis on how cool Team Rocket really isn't.
One segment in "2.B.A. Master":
So you've reached the Plateau, but not yet a hero.
Are you ready to meet and defeat...the Elite?
Can I expect survival...against your rival?
Rave Master has Rionette, one of King's Palace Guardians.
Francine's a cat who likes to rhyme. In fact she does it all the time. Well, most of the time. And only in the English version.
Minor Batman villain Humpty Dumpty also does this, frequently singing in rhyme to himself while he works on repairing things in his cell at Arkham. As observed on another page on this very site, Dumpty's rhyming skills come in handy when demons invade the asylum: the legions of Hell speak in rhyme, and those who do so naturally, like Humpty, are the equivalent of demonic-to-English translators.
The Rhyming Man, one of Mickey Mouse's enemies from comics in the 40s and recent storyline "The World To Come".
Mr. Bones of the DCU, originally; it's been quietly disposed of since then.
Peter David did actually get him to rhyme orange... with "car hinge", since he was standing on a car door.
Depending on how intrusive Etrigan is, Jason Blood's (who shares a body with Etrigan) real curse is occasionally declared to be having to listen to the demon talk all the time.
One one occasion when Etrigan had been captured by a rival demon, it was noted that him being no longer able to rhyme was an indication that his powers were waning.
Subverted in Gotham Central. Driver and MacDonald are talking to a Doctor in Arkham about The Mad Hatter.
DRIVER: I thought he rhymed, all the time.
DOCTOR: No. He's not retarded.
In an odd comic book adaptation, the RoadRunner had three sons, and they all spoke in rhyme. One story, in fact, had him seeing through the Coyote's disguise (in a road runner suit) because he couldn't rhyme.
The Leannan Sidhe in Matt Wagner's Mage does the same thing.
Suske en Wiske: Characters that speak in rhyme are often encountered (examples include "De Koning Drinkt", "Sjeik El Rojenbiet", "De Wolkeneters", "De Tamtamkloppers", "Het Rijmende Paard",...) (The King Drinks, The Cloud-Eaters, The Tamtam Knockers, The Rhyming Horse)
This is Bullhorn's entire schtick in Black Dynamite. He's stopped later on though, when he can't think of one.
Bullhorn: You're an overweight corn-fed fool with a lot of muscle mass, but now it's time for Bullhorn to get up in that ass!!
You jivin' motherfuckers would be spoilin' for a fight, if you forgot to mention a badass named Dolemite!
There's also Vince Fontaine, the jive-talking master of ceremonies at Rydell High's National Bandstand Dance-Off Contest in Grease.
Fontaine: Thank you fans and friends, and odds and ends! And now, all you gals and guys, a few words to the wise. You Jims and Sals are my best pals. And to look your best for the big contest, just be yourselves and have a ball; that's what it's all about, after all! So forget about the camera and think about the beat; we'll give the folks at home a real big treat. Don't worry about where the camera is. Just keep on dancing - that's show biz! If you're tapped on the shoulder, move to the side; let the others finish the ride. It doesn't matter if you win or lose; it's what you do with your dancing shoes! Hoo-hoo! Okay, cats - throw your mittens around your kittens and awa-ay we go!
The goblin Blix in Legend occasionally breaks into rhyme, presumably because fairy tale goblins are known for that.
Blix: Mortal world has turned to ice, 'tis a goblin paradise!
The demon that gives the wizard Ebenezum his allergy to magic in A Malady of Magicks speaks in this manner, although his rhymes are pretty bad.
"Alas, you humans are out of luck,
For now you face the demon Guxx!"
Wow, that rhyming really suxx.
A good thing, as if he could rhyme well (or had the self-control to ignore comments to the contrary) he'd be unbeatable; each rhyme he gets out acts as a combination generic counterspell and powerful self-buff, and they stack. In context he's a lot more frightening, up until the end of the third book when the collected wizards manage to spread the allergy to magic to him, forcing him to only declaim in (rather decent) blank verse.
While the main character of Inside Out by Terry Trueman doesn't rhyme his speech, the voices in his head speak almost entirely in gibberish rhymes. They only speak in a straightforward fashion when they're giving him instructions.
There's a scene in the first Kingdom Keepers book where Finn's thoughts suddenly manifest themselves as such. Amanda tells him it's a sign of witches.
In Scott Corbett's The Limerick Trick a formula produced by a mysterious boys' chemistry set with nearly-illegible labels made several of the main characters start talking like this.
In The Fellowship of the Ring, Tom Bombadil speaks in rhyming verse so often that the index of poems in The Lord of the Rings doesn't bother to list his verses individually.
In Robert Arthur's "Mr. Milton's Gift" one Homer Milton entered a mysterious curio shop in search of an anniversary present for his wife and, after making an offhand comment about the "gift of making money," was given it - along with the "gift of verse" as a bonus, because of his name. This resulted in exchanges like the following attempted explanation to his lawyer when he discovered that the "gift of making money" was somewhat more literal than he'd expected:
"I tried to buy my wife a present, something she'd consider pleasant. I didn't want her to be vexed, so I wound up getting hexed. A gift this Clarence fellow sold me, but the thing he never told me was I'd be a counterfeiter-"
Uyulala from The NeverEnding Story. In fact, she can't speak without rhyming, and also cannot hear people if they do not talk to her in verse. (Atreyu manages to get a knack for it rather quickly.)
In David Brin's Uplift series the dolphin language Trinary is expressed in (often rather snarky) limericks. Though later generations of "fin" can speak Anglic and usually don't bother rhyming when they do so.
In The Viscount of Adrilankha Ibronka and Röaana do this as a game.
-Is it something living?
-The answer no I am giving, and it is not the sky.
The children's book The Wonderful O is full of this, since the premise is that the villains ban one rather vital letter of the English language. So, naturally, they must demonstrate the difficulties this creates in poetry and verse.
The 13 Clocks slips in and out of rhyme, but manages to make it work even at the most dramatic moments:
"I have no tears," said Hagga. "Once I wept when ships were overdue, or brooks ran dry, or tangerines were overripe, or sheep got something in their eye. I weep no more," said Hagga. Her eyes were dry as desert and her mouth seemed made of stone. "I have turned a thousand persons gemless from my door. Come in," she said. "I weep no more."
Many fae type creatures in fairytales and literature speak in rhyme, including, but not limited to:
Puck and some of the other lesser Fairies in A Midsummer Night's Dream speak entirely or almost entirely in rhyme, while Titania and Oberon mostly don't bother. This may or may not be intentional.
Live Action TV, worth just a Fraction of Thee
A one-time sketch on The Amanda Show featured a "gifted class" full of teenagers with special powers. Josh Peck played Billy, a boy with the gift of "super-rhyming" ("Yeah! I do it all the time...ing."). This led to such couplets as:
Lisa: You're giving us a pop quiz?!
Billy: If you spill a soda, you have to...mop fizz.
Student: Come on, guys, let's go eat.
Billy: You don't need shoes if you got no feet!
Are You Afraid of the Dark? had the Carnie from "The Tale of Laughing In The Dark", who played the trope for all the creepiness it was worth:
Carnie: It's the most fun in the park, when you're laughing in the dark.
Carnie: Pick the right door and you'll go free, pick the wrong door and there he'll be.
This happened to Murdock in an episode of The A-Team where he had to give an injured B. A. some of his blood. Murdock uses this new tendency to try to convince B. A. that he will go insane after receiving the blood.
Murdock: You'll start hearin' thing you don't see, and rhymin' your words...just like me." *cheeky (and slightly maniacal) smile*
In an episode of Legend of the Seeker, all women are expected to do this in the presence of the Margrave. To do otherwise would be disrespecful. Cara, at first, has trouble doing this when pretending to be a princess whose skill at poetry is legendary. She does spout a few rhymes later (mostly about torture and murder) and another one later, while turning the Margrave into a punching bag. Zedd, dressed up as a duchess, has no trouble rhyming. Even more impressive, the Margrave's sister is able to rhyme while sobbing at the top of her lungs.
Queen Mab from Merlin (the TV show, not the mini-series).
Hate Master: "Would you give in already?! Doing this is no snap! It really isn't easy talking all the time in rap!"
The Rangers also had an ally who did this, Quagmire from the "Isle of Illusions" two-part episode. (Although, not all his rhymes made complete sense. For example, he referred to Madame Woe (a Monster of the Week who appeared in a previous episode) as a "nightmare queen" who Billy fought in a "realm of dreams", which really didn't describe Madame Woe or the actual battle at all.
The basic objective of the 1975 ABC game show Rhyme And Reason. A couplet is presented, and two contestants secretly write down a word that rhymes with the last word of the couplet. They select a celebrity on a panel (of six) and the celebrity completes the couplet. Matching the contestant's word scores points.
How could we possibly avoid mentioning Professional Wrestling great "Superstar" Billy Graham, the sensation of the nation and the number-one creation? He was filled with the desire to inspire, and took on all contenders and pretenders.
Muffy The Mouse from Today's Special.
On The West Wing, one of the signs that the Chief Justice of the Supreme Court is getting senile is that he tends to write opinions in verse. This is Played for Laughs the first few times it comes up:
President Bartlet: (reading) "Fear of cancer from asbestos ... fuzzy science manifestos ..."
Due to the improvisational nature of a show like Whose Line Is It Anyway?, any game that involves singing ends up becoming this. It's most obvious in Hoedown, where you can tell that the guys are struggling to come up with rhymes as they're singing.
3rd Rock from the Sun featured Laurie Metcalfe as a character who always rhymed her sentences with whatever someone else had just uttered. Dick found this charming at first but later discovered it was incredibly annoying and made it impossible to carry on a normal conversation with her.
A magic mirror in The 10th Kingdom speaks entirely in rhyme and will only answer questions that are put in verse as well. This leads to Tony and Virginia having to come up with...interesting questions on the spot.
"Our mirror's smashed, what can we do? Where the hell are the other two?"
Pinballs we play to get Specials all day
The advertising flyer for Stern's Ali is filled with rhymes extoling the virtues of the game. Needless to say, some of them stretch painfully to make a point:
Muhammad Ali: "A fast fortune is easy to earn, Just go with a winner like I did with Stern!"* Merlin in Medieval Madness almost always speaks like this.
"It's not tragic, you have Merlin's magic!"
Theater (By Playwrights With Names Like Peter of Exeter)
Gruntilda, the villain of Banjo-Kazooie. She stopped talking like this in the sequel, at the insistence of her sisters, but returned to full form in Nuts & Bolts. Probably because her sisters weren't around to nag her anymore.
The Red Caps in City of Heroes speak like this. At one point their leader Snaptooth can be seen shouting at one of them to stop.
The song "A Pirate I Was Meant To Be," from The Curse of Monkey Island, is sung by pirates who Rhyme On A Dime. The only way to end the song and escape the puzzle is to end a line with the unrhymable word "orange."
To be fair, one of them does rhyme it with "door hinge", but the others realize it wouldn't fit in with the song, so it ends anyway.
There is also an extended swordplay puzzle (Insult Swordfighting) where combat is mostly verbal and the pirate who comes up with the better insult wins. When swordfighting at sea, the insult and counterinsult have to rhyme. ("When your father first saw you, he must have been mortified."/"You're a disgrace to your species, you're so undignified!" "At least mine can be identified.") Even Guybrush and Captain René Rottingham get this rhyming exchange after the former's victory over the latter.
Micheal Tillotson from Deadly Premonition. Especially exceptional because he's not only creating a rhyme at the drop of a dime, but he's also repeating what Mr. Stewart whispers to him. Who does not speak in rhyme.
In Divinity II: The Dragon Knight Saga, we have Bellegar, a crazy mage whose lines are all rhymed. Some of them are really funny. Taken up to eleven in the expansion where his couplets turn into verses with more intricate rhyme schemes to match with his more important role.
The court jester in The Excellent Dizzy Adventure speaks exactly in this way.
Professor Shantotto of Final Fantasy XI. Rather odd, considering she serves as her nation's ambassador to conferences with major world leaders, and no one seems to call her out on her odd speech patterns.
Probably because they're terrified of her.
I am not sure which is more of an understatement in the above sentence, "probably" or "terrified".
It's not really-weally thataru odd when you considery that the vastaru majority of Windurstian Tarutaru spin-sparingly-speak with some form of Verbal Tic. Shantotto honestly has one of the less irritating manners of speech-ethy.
Naturally, Shantotto's appearances in the Dissidia: Final Fantasy games have her retain her habit of rhyming, though she rarely sticks to any sort of meter.
Shantotto: I don't make threats! If there's no result by the time I'm done researching the ultimate spell, it's too late for regrets!
The supervillain Deja Vu can't speak without rhyming in Freedom Force.
In Primordia, Primer aka137th Legionbuilt constantly speaks in rhyme, much to Crispin's annoyance. It is explained that he went crazy due to locking away most of his memory in order not to think about his defeat during the War of the Four Cities.
In Friendship is Witchcraft, Zecora is introduced as "the whimsical rhyming zebra", but she turns out to be terrible at it. In her very first speech, she trips herself up by ending a line with "circle". Later, she has trouble finding a rhyme for "sad", and just reuses "sad" three more times.
Crackotage of the Cheat Commandos. Granted, he's a parody of this kind of character and as such, he's not very good at it
CRACKOTAGE: Movie night is my favorite night. I think it is my favorite night. Hee hee hoo hoo! SILENT RIP: Are you even trying anymore?
In an Easter egg at the end of the toon in question where the above dialog takes place, this little exchange is heard:
SILENT RIP: Aw, you can do it. Try another one. CRACKOTAGE: I think my rhymes are truly broke. Broke, broke, broke, broke, broke, broke, broke! Hoo-hoo, hweh-hweh!
Strong Bad also delves into this in one Strong Bad Email, "ghosts". After scanning Strong Badia to see if it's haunted but finding nothing, he says, "Looks like Strong Badia is ghost-free, proud to be." But then, he discovers an actual ghost, that of his old computer.
Ultra Fast Pony portrays Zecora as a rapper, complete with a backing beat when she spits her verses. Of course, her skills are the result of brainstorming rhymes in her free time, and she'll talk normally if people catch her off-guard (or she just doesn't give a damn). And most of her raps only rhyme because they abuse Word Salad Lyrics.
Web Comics, Increasingly a Part of the Publishing Economics
A bard in Chasing The Sunset speaks only in rhyme. In one panel she is interrupted mid-sentence (twice) and is 'stuck' until she finds a way to rhyme her two previous utterances. And her name? Rhyme, of course.
The fairies in the Forest of Doom, in The Heroes of Middlecenter, speak entirely in rhyme. Unfortunately, Darklight... doesn't really like rhyme so much.
Ernst in Marla does this, both in his writing and his speech.
A Penny Arcade strip once featured Gabe trying his hand at this. Of course, Tycho's vocabulary is far too extensive to merely throw in a 'Purple' or 'Orange'... instead, he works 'acquiesce' into the end of a sentence, with dire consequence.
In episodes 12 and 13 of Chuggaaconroy's Let's Play of Super Paper Mario, he starts accidentally taking in rhyme (due to reading Merlee's speech), and then keeps on accidentally rhyming thoughout those two episodes
SCP-904 is a poem that, when read, forces the reader to speak in rhyme.
In The Fairly OddParents, there are the employees of "Flappy Bob's Happy Peppy Camp and Learn-a-torium", Happy Peppy Betty and Gary. They not only rhyme almost all their sentences, they also sing them, and tend to complete each other's sentences!
Betty: And, umm... Gary! I'm all out of rhimy-whimies!
Gary:That was a rhimy-whimy!
Subverted by the Gigglepies, who start out talking like this, until Timmy asks what they do once they've extracted all the resources from a planet:
Home Movies - Brendon makes a video PSA to keep kids from putting marbles in their noses, but his puppet Spiky Mc Marbles, with his rhyming speech and his snarky attitude, makes kids want to put marbles in their noses.
Zecora, particularly impressive in "The Cutie Pox", where she sets herself up to make a rhyme with "tooth" before she sees that Apple Bloom chipped her tooth (From Apple Bloom's posture, it was an easy guess).
Although there was a gag in the main MLP comic #9 where she noted (In rhyme, naturally) that she needed a moment to think up a rhyme for her next comment.
Not as frequently as Zecora, but Pinkie Pie still likes to rhyme a lot... especially when she's singing.
Discord. Not as often as Zecora, mind you, but loves handing out torturous riddles. He normally sounds far more menacing while doing so as well.
Francine always made room for a nice little rhyme, just before the great big boom signaled the Samurai Pizza Cats were off to fight crime.
While his isn't usually an example, the Green Goblin of the The Spectacular Spider-Man does this in "Opening Night". Not only is it lampshaded, but it's also partially justified: several of his lines are quotes from Shakespeare's verse. It also acts as a clue to the Goblin's identity: Harry Osborn, the prime suspect behind the mask, was supposed to be playing Puck in a school play, and all of the Shakespeare lines are Puck quotes. Turned out to be a Red Herring, but nice touch...
The wicked sorcerer Zig Zag from The Thief and the Cobbler rhymes whenever he speaks, often rather elaborately. He actually manages to be both amusing and menacing in this way. For example, when he said "One mistake will suffice! Don't treat me lightly twice!" after taming the alligators he had been thrown to by the ungrateful Big Bad One Eye.
Lampshaded in the infamous Miramax cut when the thief, overhearing one of Zig Zag's private rants, comments to himself, "It must be tough to always speak in rhyme."
Several locomotives actually started to speak in rhyme at times in the more recent episodes of Thomas the Tank Engine. It is getting mercifully downplayed however.
The title character of the Courage the Cowardly Dog episode "Freaky Fred" does this, remarkable because he's the villain and the episode is told from his point of view.
The live-action version of the character also does it, albeit a tad more sparingly:
Underdog: (melodramatic) My rhymes are only said in fun! (normal) Okay, I'm done.
What's with Andy had an episode where Andy was dared to speak in rhyme for an entire day. He mastered it pretty well, up until he was challenged to rhyme the word 'orange'. Which he succeeded; it rhymes with 'door hinge'.
One episode of Wow! Wow! Wubbzy! featured the Hopping Dipple-Dop, a character who only spoke in rhymes.
