His Dark Materials has the Panserbjørne, the Guardians of the Svalbard archipelago, a race of armor-clad warrior polar bears (in fact, "panserbjørne" is Danish for "armored bears"). As a matter of fact, the author gleefully tells us that This Is The Coolest Thing Ever.
20,000 Leagues Under the Sea. Pirates, a nuclear Steam Punk submarine, giant underwater monsters, and a mad scientist.
Peter Pan is an early version of this: flying immortal juvenile delinquents fight pirates, Indians, and demonic crocodiles in a bizarre fantasy land inhabited by mermaids and fairies—which makes this Older Than Radio.
The Disney animated adaptation has said juvenile delinquents wear animal skins.
In the 1991 Steven Spielberg spinoff Hook, those same delinquents are now multiracial punk skateboarders who fire catapults full of eggs.
The Princess 99 has an alien punk rocker from the future fighting zombies, elves, and wizards in a mixed up Clock Punk fantasy setting that's based on 1920s New Orleans...but with wizards!
Certain Discworld stories might count as this, considering just how many bizarre concepts tend to be packed into one novel. A good example would be Monstrous Regiment in which a Sweet Polly Oliver joins a military regiment along with a troll, a vampire, two women who happen to be in love - one of them is a pyromaniac and the other is perpetually angry, a religious fanatic who bears a strong resemblance to Joan of Arc, a sergeant and an Igor and they all fight in a war in the name of a god who is dead, and a dead mortal who is in the process of ascending to godhood. And it turns out the entire regiment is an Amazon Brigade and didn't know it.
Carpe Jugulum is a book about witches fighting vampires, with the help of Violent GlaswegianSmurfs, a phoenix, and a fighting priest. Also, The Virus is inverted: "I ain't been vampired. You've been Weatherwaxed."
In Dune, there are a few different characters with special abilities. There are the Navigators, who can see in four dimensions. There are Mentats, essentially human computers. There are also the Bene Gesserits, magical witches that have the commanding Voice. And then there's Paul Atreides, the Kwisatz Haderach. This Troper's nickname for him is Paul "multiclasses-in-everything" Atreides, because he is essentially ALL OF THESE! The only person worse than him is his son, who even jumps species to get the extra skills he didn't already inherit from his father.
There's also the overarching story about a depressed widower astronomer and a womanizing, land-surveying Quaker studying the orbit of Venus while snarking all over Dutch people and then measuring borders IN AMERICA while discussing dragons. And that bit is true. Less true are the talking dog who knows everything, the Chinese fung shui master who is afraid of turning into a Spaniard, the rabbi secret agents trying to track down rogue golems, golems built by Jesus, the Swedish conspiracy, the Spanish Inquisition's involvement, the ghost, and some witches. And it's all written in Antiquated Linguistics.
Peter F. Hamilton's Night's Dawn trilogy is the story of humans fighting back againstan invasion by dead souls possessing the living to escape a horrible living death afterlife and gaining superpowers in the process unleashed when an alien made of pure energy interrupts a satanic ritual and nearly winning until Al Capone comes back and takes over whole star systems then the dead take some planets to over universes except one is a horrific nightmare realm with an enemy made up of a squillion different species liquefied and mashed together into a blob of pure scary and then the guy who started it all summons the scary blob to our universe and everybody nearly dies but someone else saves the day by piloting a living starship to where a god hangs out and talks it into helping. The impressive part is this is actually done in such a way that every premise is plausible and the impacts they have on the world are realistic.
Pandora's Star is about an empire of far-flung planets connected by trains that has been infiltrated by aliens that escaped from a Dyson Sphere before its completion by Sufficiently Advanced Aliens that moved on to bigger things. One hero's quest is guided by elves who trigggered the Earth tales of The Fair Folk, who seem to be unconcerned with the fate of man and who travel between planets by walking. There's also a lot of sex.
Elizabeth Bear's Edda of Burdens series: as of Book One: All The Windwracked Stars, we have a post-apocalyptic steampunk valkyrie historian, a two-headed immortal flying cyborg warhorse, magico-genetically spliced catgirl police officers with the souls of dead angels, reincarnated rentboys with superstrength, and a few completely casual mentions of battle shoggoths.
Complete World Knowledge. Hoboes, presidents, mole-men, cane swords, ferrets, giant iguanas, druids, masturbation out a window, Jonathan Coulton, zeppelins, Time Lords, a sequel to The Catcher In The Rye, samurai, thunderbirds... apparently the only thing that doesn't exist in John Hodgman's mind is Chicago.
Followed by Mansfield Park and Mummies, which features spirits of ancient Egyptian pharoahs, vampires, collections of ancient Egyptian artifacts, and mummies.
Followed by Emma and the Werewolves. Stand by for the next two — no doubt it will be a short wait...
The Gone-Away World by Nick Harkaway. How to describe it? An Afterthe EndCatch-22 cowritten by Thomas Pynchon and Douglas Adams by way of Fight Club with heroic Hazmat troubleshooters vs the evil megacorp. And oh yeah, ninjas vs kung fu mimes
Tobias Buckell started writing Crystal Rain by listing all the cool things he could think of. Mongoose men fight Aztecs with zeppelins, while the pirate hero (at least he has a hook and likes to sail) battles amnesia on a steampunk quest to the frozen north to recover the secrets of their offworld ancestors. And Sly Mongoose has sky cities and space zombies.
The Crazy Awesome nature of The Dresden Files cannot be overemphasized. A polka-powered zombie tyrannosaurus! A cult of porn-star sorceresses! Ninja ghouls! Paladins with Kalashnikovs! Secret agent demon werewolves! A wizard with a vampire hairstylist brother! And so on and so forth.
The Codex Alera series by the same author is full of this too. From the page description: "Magical Roman Legionnaires straight out of Avatar The Last Airbender versus the Zerg. And wolfmen with Blood Magic. And telepathic yetis. And white-haired neanderthal-elves. Riding ground sloths and terror birds..." And, later: "The political dealings of Dune meets a Greco-Roman Society powered by Pokémon." That leaves out the parts where some of the wolfmen get zombified (or maybe "possessed by body-snatching aliens" is a better description), the Zerg learn magic, and a Chrome Champion swordfights.
The aforementioned wolfmen have morals and values at least partially influenced by fuedal Japan - which means that not only do we get wolfman samurai-analogues, but we also get wolfman ninjas.
Jasper Fforde's Thursday Next series (and the related Nursery Crimes series) focus on the titular protagonist's adventures in Book World, where all characters in fiction are the roles played by Book World actors. Gully Foyle of The Stars My Destination polices Science Fiction. The Racy Novels genre is in a border dispute with Feminist. Her uncle Mycroft, a mad inventor, is sought by a multinational corporation for his latest invention, the Book Portal (which started the whole mess), so he hides in the backstory of the Sherlock Holmes series - as Sherlock's elder brother. If a reference sounds vaguely literary, it is. In the "real world", things are even stranger - cloned Neanderthals, dodos, and thylacines exist, as do time travel, werewolves, and the radical Bacon Society, which claims Francis Bacon wrote Shakespeare's plays, and is willing to start riots in the streets to prove their point. If you plan to visit, bring a clear jar filled with lentils and rice, and shake it every once in a while. If the mix starts clumping as if something was sorting it, watch out, entropy's going backward.
'It was about this pirate who was a famous detective (...) 'Specially the bit in the spaceship where the dinosaur comes out and fights with the cowboys'

Neal Stephenson's novel Snow Crash features as it's main character Hiro Protagonist, a ninja computer-hacker pizza delivery boy, who invented the Matrix.
Clive Barker's "Son of Celluloid" stacks real-life Body Horror on fantasy horror, in that the villain of the story is a sentient, mind-manipulating, reality-warping undead cancer tumor.
The prose of writer Francesca Lia Block often comes off like a "girly" version of this trope. For example:
"A kiss about apple pie a la mode with the vanilla creaminess melting in the pie heat. A kiss about chocolate when you haven’t eaten chocolate in a year. A kiss about palm trees speeding by, trailing pink clouds when you drive down the strip sizzling with champagne. A kiss about spotlights fanning the sky and the swollen sea spilling like tears all over your legs."
Zal is both types ofelvish, demonic (not entirely by birth), and a rock star. Also, that spoiler at the beginning means he's got some failed experiment with the void going on in his background.
Lila is a Cyborg, who is also a spy and a bodyguard and has a dead elf necromancer in her chest for a while. Ah, the power of being around someone with harmonizing powers...
Tath is an elvish necromancer, which is already weird, though he is not the only one. Then the story progresses, and he also becomes part fey, and dies and is reborn. Twice.
Theoretical here: It appears to be possible to be a demonic, elven, fey necromancer who is/was part machine and then become a ghost while technically keeping all of the former (rock star or other training also applicable), just so long as one doesn't start out human. Because humans are passive with magic.
Gemma Files's Hexslinger series: An alternate history/dark fantasy/Wild West adventure with a gang of outlaws and robbers led by a Hard Gay couple, one of whom is a former corrupt preacher turned dark sorcerer, the other of whom is an expert sharpshooter and potential sorcerer who becomes the vessel of an an Aztec god, who aid in the resurrection of a power-hungry Mayan goddess. The series also features a Navajo medicine woman, real-life historical figure Allan Pinkerton leading a secret group that scientifically studies the workings of magic and sends spies to monitor the sorcerous outlaws, and an evil Chinese albino sorceress who is also a child prostitute. And the genuinely pious minister who is implied to have been resurrected by an angel in order to fight the evil sorcerers. All of this is just from the first book.
Clash of the Geeks is a short-story collection (and fundraiser for the Lupus Foundation of America) themed around a picture of Wil Wheaton wielding a lance, riding a unicorn pegasus kitten, and wearing a clown sweater, while attacking an orcish version of John Scalzi.
Fairly easy way to explain the Bene Gesserit: Eugenicist Psychic Ninja Slut Nuns
In On Stranger Tides, historical pirate Blackbeard is a voodoo sorcerer with zombie minions, and a rival sorcerer raises a shipfull of pirates and another ship from the Spanish navy, although that was by accident as animated skeletons.
Jasper Jones.
Jeffrey Lu, upon learning that his friend Charlie had a nightmare about the Wizard of Oz: "Really? But there are so many cooler things to have nightmares about. Like sharks. Communist sharks, with razor-sharp fins that can walk on land."
An obviously best-selling novel that Jeffrey and Charlie wrote together was about an ex-cop turned archaeologist called Truth McJustice who, among too many other awesome exploits to mention, discovers the Holy Grail and does martial-arts battle with an imposter Pope.
The main character Unda Vosari: Legends, Captain Vincent Lorimar, had training by ninjas in his younger years, took to the seas and became a pirate to fight his arch-enemy, Baron Calavera.
