Hotblack Desiato, which is actually the name of rather posh, London estate agents.
Zaphod Beeblebrox, fitting his eccentric rock star/politician/dingbat personality.
"Slartibartfast," which was created to sound obscene but not be. Adams started with Phartiphukborlz and changed it just enough to get past the censors.
And, of course, Ford Prefect, although it sounds much cooler to American readers who mostly didn't realize that he's actually named after a sensible British motorcar.
Unknowingly, Douglas Adams actually picked a real name - there was a young boy acting in BBC1 children's drama Byker Grove whose name really was Ford Prefect.
This trope is exemplified by the persona created by Discworld character Agnes Nitt, Perdita X Dream, where X stands for "person who has a cool and interesting middle name"; when Agnes tells other people she'd like to be called this, they usually end up calling her "that Agnes who wants to be called Perditax". In the novel Carpe Jugulum, it was further parodied when the vampire equivalent to Goths were changing their names to extremely drab or 'preppy' names. "Lady Strigoiul said her daughter has taken to calling herself Wendy."
Also Mightily Oats, a shortened form of "The Quite Reverend Mightily-Praiseworthy-Are-Ye-Who-Exalteth-Om Oats".
Wherever Oats goes these days, he brings Forgiveness with him. Forgiveness is his double-headed battleaxe.
The one-shot vampire from "Feet of Clay", Dragon King-of-Arms.
That's actually a title rather than a name. "Dragon" is the head of the Ankh-Morpork College of Arms, which is based on the real British College of Arms, an office of the Royal Household. The College is composed of 13 officers of arms (a.k.a. heralds), including at the time of writing Garter Principal King of Arms, Lancaster Herald and Bluemantle Pursuivant.
The rats from The Amazing Maurice and His Educated Rodents read labels on tincans and name themselves as whatever they think sounds good. Thus you have perfectly respectable individuals named Darktan, Feedsfour, Peaches and Hamnpork. And their arguably most book smart member is named Dangerous Beans, which is a bit hard to take seriously.
One Igor had former masters with names such as Screaming Dr. Berserk and Crazed Baron Ha-Ha.
Modern Omnians have very...unusual names to the effect of Mightily-Praiseworthy-Are-Ye-Who-Exalteth-Om, Constable Visit-the-Infidel-with-Explanatory-Pamphlets and Smite-the-Unbeliever-with-Cunning-Arguments.
features Anathema Device. The Devices were a real family who were involved in witch trials in the 17th century (so were the Nutters), and Anathema is a word that has a variety of meanings in a religious context; put them together and you have a perfect set-up for scenes like Agnes's prediction that ends in the sentence "And thou shalt be there also, Anathema" — which the modern Anathema assumes (correctly, it is implied) to be addressed to her.
Thou-Shalt-Not-Commit-Adultery Pulsifer. Newton Pulsifer said he would go on a rampage as well with a name like that
it deserves notion at this point there are also main characters like 'Aziraphale' and 'Anthony J. Crowley' and minor character 'Warlock'. I dare you to find people with those names. I know I'd like to have one of them.
There's a chess-like game called Hneflbaflsniflwhifltafl, commonly nicknamed Thud!. It's a parody of a real game, Hneftafl.
Neil Gaiman's American Gods could make this list based simply on the gods' various real and assumed names, even without the protagonist's exceptionally cool name: Shadow Moon, aka Baldur Moon.
Culture Full Names are only partly names as we understand the term, and are as much addresses as anything else. (Banks suggested that his Culture Full Name might be Sun-Earther Iain El-Bonko Banks of South Queensferry.) The full names of sentient drones (like Skaffen-Amtiskaw) also provide their place of manufacture and capabilities: the main character in The Player of Games realises just how deep he's gotten when told that a "Xato" name-component designates a Special Circumstances agent equipped for espionage against other "Involved" civilisations.
Then the Minds, the more capable AIs responsible for controlling ships etc have some...odd names. Killing Time. Limiting Factor. Just Another Victim Of The Ambient Morality. Ultimate Ship The Second. No More Mr. Nice Guy. The list goes on... The Culture ships are named by their Minds, to match what they feel their personality is like. Warships tend towards more aggressive names like Gunboat Diplomat whereas civilian ships have less aggressive names (like Stranger Here Myself). When told by a critic that the Minds lacked gravitas, Iain M. Banks responded by naming a few ships in response to this (Very Little Gravitas Indeed, Zero Gravitas, and so on). Stood Far Back When the Gravitas Was Handed Out...
Philip Reeve may have been reading Culture novels when he started calling airships in his Mortal Engines series things like Damn You, Gravity! , 13th Floor Elevator, Itsy Bitsy Teeny Weeny Yellow Polka Dot Machiney and The Sadness of Things. There is also an aeroplane called Combat Wombat.
Commander Kelp in Artemis Fowl. His unit has "trouble" as their middle names, but Kelp literally has "trouble" as his first name. As in, the name on the books is "Trouble Kelp".
And of course, the title character himself, Artemis Fowl.
Two short stories by Edgar Allan Poe center around a narrator named Signora Psyche Zenobia. Only her enemies, she proclaims, ever refer to her as Suky Snobbs.
Dan Abnett loves this trope, especially in his Warhammer 40k writings. The Inquisition books give us Gregor Eisenhorn, Gideon Ravenor, Bex Begundi, Godwyn Fischig, Olm Madorthine... etc. In the Gaunt's Ghosts books the obvious one is Ibram Gaunt himself, but the most recent book, Blood Pact, gives us Isiah Mercure. He's really lucky he's the head of an intergalactic intelligence agency that spends its time fighting both the Forces of Chaos and the Inqusition, or that name would probably make his life really difficult.
There's an Aerith and Bob aesthetic, contrasting very normal character names like Harry Potter with fantastic wizard names like Albus Percival Wulfric Brian Dumbledore, Severus Snape, Tom Marvolo Riddle, Sirius Black, Gilderoy Lockhart, Xenophilius Lovegood, Fleur Delacour, Scorpius Hyperion, Lorcan and Lysander Scamander, Kingsley Shacklebolt, Bellatrix Lestrange, Draco Malfoy, Godric Gryffindor, Rowena Ravenclaw, Helga Hufflepuff, and Salazar Slytherin, Gellert Grindewald, Charity Burbage, Horace Slughorn, Alecto and Amycus Carrow, Septima Vector, Silvanus Kettleburn, Aurora Sinistra, Quirinus Quirrell, Bathsheda Babbling, Bathilda Bagshot, and so forth.
"Death Eaters" is pretty awesome. Considering that the translation to Spanish wouldn't be that cool, editors decided to use a latinized version and called them "Mortífagos" (Latin for "Mortis", Death and "Fagi", to eat), which ends up being awesome.
In the Skulduggery Pleasant series, characters take names instead of using their given names, since in this world, someone knowing your real name can give them power over you. Some of those names include Valkyrie Cain, Ghastly Bespoke, Billy-Ray Sanguine, and Murder Rose.
Skulduggery specifically advises Stephanie (who, later, takes up the name Valkyrie Cain) against choosing a "cool" name over a name that suits your personality (using a middle-aged woman known as "Jet" as an example against). Nevertheless, the names manage to sound cool AND suit the characters.
In Tamora Pierce's Circle of Magic series, all of the dedicates in Winding Circle took nature/animal names after sufficient time in the temple. Many of them are quite the Badass, despite their names generally being random.
There's also Numair Salmalin in the Tortall Universe, who made his up because he thought "Arram Draper" didn't sound badass enough for one of the world's most powerful wizards.
Maximum Ride. Other illustrious examples of this would be the flock: Iggy, Angel, the Gasman, Nudge, Total and Fang.
It's worth mentioning that Total is a dog.
At least sort of justified by the fact that they picked their own names.
Even better examples in the names they give to the talent agent in the fifth book: The White Knight, The Sharkalator, Cinnamon Allspice La Fever, and Isabella von Frankenstein Rothschild.
Wolf Larsen and Death Larsen, from The Sea Wolf by Jack London. Not quite as awesome as the other names mentioned here, but this book was written in 1904.
The gnomish race are blessed, one and all, with surnames that consist of, quite literally, everything that has happened to them in their life, and in the lives of their parents, and pretty much the rest of their family going back generations, as well. A Running Gag in the book series was unwitting people asking a gnome his name and having to interrupt the avalanche that follows.
Dragonlance pushes this trope to painful extremes. Examples include "Sturm Brightblade", "Steel Brightblade", "Alhanna Starbeeze", "Dhamon Grimwulf", "Flint Fireforge", "Huma Dragonbane", "Goldmoon", "Riverwind", "Eben Shatterstone", Cyan Bloodbane", and so forth.
Isaac Asimov, in the Foundation Series, gave a similar cultural trait to the inhabitants of Gaia (a planet-spanning telepath collective) with names such as "Blissenobiarella" and "Suranoviremblastiran" (and names said to be hundreds of syllables long, but never mentioned in full). The names are universally abbreviated in normal conversation, however.
Christopher Brookmyre's Violent GlaswegianFair Cop is named Angelique de Xavia. This is lampshaded by pretty much every other character (her colleagues call her 'Angel X' and 'Special Agent X'; when a criminal captures her at gunpoint and confiscates her ID his immediate comment is: "Cool name.").
H. Beam Piper did the same thing in his science fiction stories, giving us characters with names like Themistocles Mzangwe and Hideyoshi O'Leary.
Likewise Juan Epstein from Welcome Back Kotter.
Snow Crash: the main character's name is Hiro Protagonist, his roommate is named Vitaly Chernobyl, and his partner is Yours Truly (abbreviated to YT). These are all actually nicknames or stagenames, but the closest we come to their real names is that Hiro's full first name is "Hiroaki." On the other hand, the Aleut Dmitri "Raven" Ravinoff sports a suitably ominous and legitimate name.
Catch-22 is a treasure trove of gloriously silly and bizarre names, many of them meaningful. The hero Yossarian's exotic Armenian name indicates his detachment from the rest of the soldiers. Major Major Major is instantly promoted to the rank of Major due to his name, and can never change his rank because a mail attendant thinks it's funny. Milo Minderbinder can think of nothing but profit and capitalism. Major —— de Coverley looks so impressive that no one has the nerve to ask him his first name. Lieutenant Scheisskopf ("shithead" in German) lives up to his name, but enjoys a steady string of promotions.
Lord Peter Wimsey (an appropriately cool name on its own) sometimes while undercover calls himself by his two middle names — Death Bredon ("Some people with that particular name pronounce it to rhyme with 'teeth' but I prefer it to rhyme with 'breath' — more dramatic, what?"). And his nephew is named St. George.
Actually, "St. George" is the nephew's courtesy title (as the only son of Lord Peter's older brother, The Duke of Denver). However, both the Duke and his son were named "Gerald", and the younger Gerald was nicknamed "Gerrykins" which morphed into "Pickled Gherkins"!
Children's book series Grey Griffins has Maximilian Grayson Sumner III, a rich billionaire's kid, Harley Davidson Eisenstein, the Bad Ass, Natalia Anastasia Felicia Romanov, the smart Snooping Little Kid, and on the uncool note, Ernest Blumfeld Tweeney, The Load.
In Deathstalker's Legacy, a criminal has the unlikely moniker of Toby Goddamnit. He never says how he got his name before he dies.
How can you forget the main character? Owen Deathstalker. And that's not even going into Simon Green's other books, like The Nightside with gems like Razor Eddie, and Shotgun Suzie (aka "oh crap it's her why not just put gun to your head, it'll probably hurt less.") and that's just for starters. There's tons more. Simon seems completely unable to give his characters normal name, John Taylor being the most normal, and it's still pretty cool.
The main character of America the Beautiful (written by Moon Unit Zappa, who's got a pretty awesome name herself) is called America Throne. Granted, her father A) changed his surname from Tronov when he immigrated from Russia and B) was a crazy hippie artist. (Mer won the name lottery in her family. Her brother's name is Spoonie.)
In The Long Hot Future, the breeding program Eugenix assigns three given names, an alphanumeric code, four surnames, and an etcetera. The main character's full name is Keef Joy Brazen X-5 Lattimore Balzac Marsalis Wu Etc.
Aphrodite in The House of Night series. Justified because when fledgling vampyres enter the school, they are allowed to change their names and are legally emancipated from their parents. Being incredibly self-centred and vain, she chose the name of the goddess of love.
Patricia McKillip's The Riddle Master Of Hed trilogy features several. Alongside abnormal-but-not-too-strange names like Eliard, Mathom, Astrin, and Rood, you have a few incredibly awesome names (i.e. Ghisteslwchlohm). And then, of course, there's Deth.
James Bond was originally intended to avert this trope entirely, the name itself being picked up from the author of an ornithology book for what Fleming was the most boring name imaginable. Of course, nowadays the name is known worldwide for both the character and the brand as the epitome of cool.
From The Icemark Chronicles we have Thirrin Freer Strong-in-the-Arm Lindenshield, Wildcat of the North, Taker of the Hand of Bellorum. In fact, any non-Polypontian in that trilogy counts.
The Dresden Files: The "actors" in Blood Rites have to pick stage names, and Bobby considers names like "Rocko Stone" or "Rack McGranite". Finally, at Harry's suggestion, he goes with "Gowan Commando."
Author Jim Butcher's bichon frisé's name, Frost, is reputedly short for "Frostbite Doomreaver McBain."
Um, hello, Mr. Harry Blackstone Copperfield Dresden. Justified given the theme of the novels, but in a series loaded with Meaningful Names, Butcher also manages to make his main character's given name sound freakin' awesome.
Anastasia Luccio? Ebenezar McCoy? Margaret LeFay Dresden? Lara, Inari, and Thomas Raith? There's a lot of cool names in the Dresden Files and that's not even getting into the nonhumans. Like Lasciel or Anduriel. The Leanansidhe case is more akin to choosing a known character of the Sidhe mythos and making her close to Dresden.
The majority of the human characters in Codex Alera have awesome names as well, most of them in Gratuitous Latin. The best one? Gaius Tavarus Magnus, a.k.a. Gaius Octavian, a.k.a. Tavar, a.k.a. Rufus Scipio. Yes, Tavi gets four of them to make up for being an Odd Name Out. It simply must be noted that the first one translates to Lord Wolverine the Great. Though credit must also be given to Antillus Crassus, Antillar Maximus, Aria Placida, Gaius Sextus, Fidelias ex Cursori, Aquitainus Attis and Invidia, Araris Valerian, and Kalarus Brencis.
Author Brandon Sanderson once expressed regret in one of his online annotations that he was unable to give character "Kelsier" a cool last name like Mistshadows.
The name Starbuck may signal Herman Melville's penchant for symbolism in Moby-Dick, but it also signaled "awesome" to both TV sci-fi (Battlestar Galactica) and Seattle coffeehouse proprietors.
It certainly signaled "awesome" to Bill Starbuck, who changed his name from Smith because that didn't suit a man like him (who also considers "Lizzie" too prosaic a name for a woman — "why, it don't stand for anything!").
Thomas Pynchon: Pirate Prentice, Oedipa Maas, Patience Eggslap, Tyrone Slothrop, Mike Fallopian, Ronald Cherrycoke, and Clayton "Bloody" Chiclitz.
Honor Harrington, though the first name "Honor" is actually part of a fairly common tradition of using virtues as female first names, such as "Chastity" and "Grace."
Everworld has an elf character who is actually named Mac Cool, and it's a Meaningful Name, with the character ultimately turning out to be Too Cool to Live. He's also the "Bob" of Aerith and Bob, since the other members of his elven culture have more traditional Celtic names like Etain, Goewynne, and Camulos.
Actually, Mac Cool is a pretty Celtic name, since Finn Mac Cool is the Anglicised version of Irish legendary hero Fionn Mac Cumhaill. In fact, it's the kind of Celtic name you might come up with if you didn't know very many Celtic names.
Francesca Lia Block is all over this trope, possibly due to her own name. She justifies this in part by creating a lot of mother characters who would totally name their kids things like Duck, Witch Baby, (a very pale blonde) Cherokee...and so by extension it gets oddly believable that there would be a kid out there named My Secret Agent Lover Man. It also helps that the stories are supposed to be like fairy tales.
Let's not forget D.B.C. ( stands for "Dirty But Clean") Pierre's Man Booker Prize winning protagonist Vernon God Little.
In Dean Koontz's From the Corner of His Eye, the villain (named Enoch Cain, naturally) learns from a newspaper article that one of his victims was named Kickmule. He's surprised to learn Kickmule is a legitimate name, and since it's so badass decides to use it in the future if he ever needs another alias ("no one would ever mess with Wolfgang Kickmule").
From the manuscript of a friend: the Anti-Hero: Rhenxonemor Farrenghan, a.k.a. "Rhen". The Heroes: Seth Darkthorn and Max Rose. Two of the villains: Luna Darkthorn and Dark Pane. The Bad Ass villain: Nicholas Xerxes Strife-Darkstar. The mega-villain: Sindrenomy and the Soul Carvers.
Does this manuscript happen to have a character named Lawrence Reaper?
Warrior Cats is in general kind of a crapshoot with names. Characters like Tigerclaw, Lionblaze, Fireheart, etc. exist alongside the more boringly named cats (Graystripe, Bluefur, etc.) and cats with names that, from a human perspective, can seem outright stupid (Loudbelly, Mudpuddle, etc.)
Lyra Belacqua in His Dark Materials, though she later trades it in for Silvertongue. But the names of characters' dæmons tend to be melodious and exotic - like Pantalaimon, Stelamaria, Zohariel, and Kirjava.
The Reverend Doctor Syn in Russell Thorndike's series of books.
Victorian authors did this often, but a master at it was Anthony Trollope. who conjured up a Duke of Omnium Gatherem, doctors Sir Omicron Pi and Dr. Fillgrave, a country rector with many children: Mr. Quiverfull, the totally bland and effaced Lord Fawn, among many others.
The titular character of Alyzon Whitestarr. The author claimed to have met a family while on a walk, and liked the daughter's name so much that she decided to use it for her book. There is a real person out there with that name. (Maybe.)
Practically every Vampire and Vampanese in The Saga of Darren Shan (Cirque du Freak Series US) has an amazing name. Who can't like names like Larten Crepsley, Vancha March, Arra Sails, Gannen Harst... the list goes on and on. Even the grotesque-looking little person, Harkat Mulds, has an amazing name, especially considering as it is an anagram of his name from before he became a little person, Kurda Smahlt.
Ark Angel from the Alex Rider series feature a man named Magnus Payne. He is actually an alias of the Big Bad, himself known only as Kaspar.
Many dragon species in How to Train Your Dragon have awesome names. For example: Rocket Ripper, Windwalker, Saber-Tooth, Monstrous Nightmare, Skullion, Monstrous Stragnulator, Sharkworm, Venomous Vorpent, Deadly Nightshade, Exterminator, Raptortongue, Polar Serpent, Burrowing Slitherfang, Deadly Shadow, Silver Phantom, and, the king of them all: Seadragonus Giganticus Maximus, The Doomfang, The Darkbreather.
Several of the individual dragons' names count as well, such as Fireworm, Killer, and Stormfly. And some of the humans' names, such as Humongously Hotshot the Hero or Flashburn the Flashmaster.
Most of the mantically-aware from the Mediochre Q Seth Series choose their own name, and so most of them of course choose one of these. Notable examples:
The title character himself, of course. The Q stands for Quirinius.
Alot of the names in this series could count. Eddard Stark, John Snow, Theon Greyjoy, The Clegane brothers, Khal Drogo, and Stannis Baratheon spring to mind
In the final book of the Doom novels, due to an inability to compromise between two equally unwieldy epic names, a ship is christened "Great Descent into Maelstrom of Solar Flare of Righteous Vengeance Against Enemies of the People's State."
H. P. Lovecraft (who had a badass name himself) had a knack for creating badass names for his horrors, with examples such as: Azathoth (a memo he wrote to himself regarding it simply said 'AZATHOTH - hideous name') aka The Nuclear Chaos and Nyarlathotep aka The Crawling Chaos aka The Haunter of the Dark. There's a reason the metal community likes Lovecraft so much.
By Blood Alone (the second book in the lengthy series about the (No longer) French (No Longer) Foreign Legion IN SPACE!) has a section that takes place during travel on a ship called The Warm Wind That Blows Happiness Through The Universe, or as her crew affectionately know her, The Iron Bitch.
GONE is a subversion; some characters have names Sam or Mary, but then you have some characters called Orc, Pack Leader, Sanjit ("It means invincible! I can't be vinced! Go ahead, try and vince me!"), Caine Soren, Toto, Astrid, Hunter and THE GAIAPHAGE.
A particularly fine example from H.I.V.E., as well as Doctor Maximilian Nero, is the world-famous master criminal Diabolous Darkdoom.
