"They invaded Greece and conquered them and and stole all their gods and renamed them with Roman names. Cause the Roman gods before that were kind of crap, you know, Jeff, the god of biscuits. And Simon, the god of hairdos. And uh, you know, they had the god of war, the god of thunder, the god of running around and jumping and stuff."
In Kamichu!, a very shinto-derived series, you even see gods for empty aluminum cans, ice cream bars, and cheap grocery store mascots.
In One Piece, Sanji brings up this phenomenon in order to encourage Usopp, since they're on their way to defy and confront "God Enel" of Skypeia. A rough quote:
"Not all gods are powerful and dangerous, you know. Like the god of being poor."note Yes, there is such a thing in Japanese folklore. It's called a "binbougami."
In another shinto-inspired example, Spirited Away includes entities such as the alleged Stench Spirit, and the Radish Spirit.
The title character of Binbougami ga! is the goddess of poverty and misfortune.
Vext was a short-lived series from DC Comics about the God of Mishap and Misfortune. It included a number of other small-time godlings, including the deities of uninvited guests, relationships gone hellishly wrong, incessant nagging, and ill-timed flatulence.
In PS238, there's a goddess in the Rainmaker Program (where superkids whose powers don't exactly lend themselves to fighting crime learn to use them in other ways). It's the Greek Hestia, goddess of the hearth. They're thinking advice columnist, fertility clinician, marriage counselor... just don't come in uninvited.
In The Sandman we meet Pharamond, from the Babylonian pantheon, who is now "in charge of transportation." He appears to be more or less a travel agent for the puissant.
He, in fact, managed a massive transportation firm.
With the fringe benefit of being able to count road traffic deaths as sacrifices in his name. He was quite happy with his new place in the order of things.
In Lucifer we are given Mona, Angel of Hedgehogs (a job she chose in order to avoid taking on too much responsibility). The only other god in her universe is Elaine, Angel of everything except hedgehogs.
A Donald Duck comic featured him taking odd jobs as the god of, among other things, cars and television. He managed to botch the job so badly he sent Duckburg's technical prowess back to the 17th century.
Spinal Tap's David St. Hubbins' surname is derived from the patron saint of quality footwear.
Note that the actual saints of footwear are the duo Crispin and Crispinian. Yeah, there are patron saints for everything, see below.
In the short film A Case of Spring Fever, our protagonist encounters Coily the Spring Sprite, a seemingly-omnipotent being (or at least a high-powered Reality Warper) that has an odd preoccupation with springs.
The Mystery Science Theater 3000 sketch inspired by it goes even further, implying that not only is there a tiny sprite that governs Mike's existence and can erase him from reality if someone wishes it, but there's a different sprite just for his socks.
In My Name is Bruce, the town of Gold Lick is menaced by the Chinese warrior-god of bean curd.
Discworld: A blink-and-you'll-miss-it explanation for why many gods end up with weird coverage areas tacked on: Old gods do new jobs. The verse has among other things:
Aniger, the minor goddess of squashed animals (growing in power as carts get faster and roads get smoother and more people cry out, "Oh gods, what was that I hit?!"), possibly connected to Herne The Hunted, God of things destined to live short lives ending in a crunch.
Anoia, minor goddess of Things That Get Stuck in Drawers formerly a volcano goddess...who is heading up; she's currently tapped to be the new Goddess of Lost Causes, a growth industry on the Disc.
Bilious, the oh God of Hangovers, whose newfound existence allows the God of Wine to drink as much as he likes and never get a hangover (and incidentally allows humans with the same trait to do it too) eventually decides to do freelance godding for any gods that want to take a break.
Errata, the Goddess of Misunderstandings (from Discworld Noir), famous for having the largest number of followers who, by mistake, follow a different god.
The heroic dog who stole the Tsortian Falchion and became the god of Unnecessary Subplots In Legends.
Nuggan, the recently deceased God of Paperclips, Correct Things in the Right Place in Small Desk Stationery Sets, and Unnecessary Paperwork
The Hogfather, the god of Hogswatch. Oh, and the sunrise (more Spring than sunrise, as he is a Winter Solstice god).
All of the above is just in the mainstream pantheon. There's also oddballs like P'Tang-P'Tang and Quetzovercoatl ... or even think about Djelibeybi.
Lampshaded in Mort, when Cutwell, trying to get the coronation done as fast as possible before reality collapses in on itself, realises to his horror that the officiating priest is going to name all 900 known gods. He gets as far as Steikhegel, God of Isolated Cow Byres before someone stops him.
Another Lampshading in Small Gods, where Om mentions there's a God of Cabbage. Thunder gods may come and go, but when there's an attack of caterpillars, whom does everyone turn to?
In Reaper Man, when we get Hughnon Ridcully's delightful summation of events in Cori Celesti...
Small gods are what are created when random events occur (eg two snails crossing paths, or someone catching a dropped pen etc) or as in Witches Abroad, when a practitioner of the voodoo style of witchcraft sets out to make a few gods to order. A little headology to get people to believe in them is all you really need to do so; heck, C.M.O.T. Dibbler may have created the Black Dragon of Unhappiness by accident when he convinced a feng shui customer it existed!
In a variation of this trope, Discworld also has multiple Deaths. Like a Death of Rats. (This wasn't always the case; the extra Deaths were created during the events of Reaper Man; by the end of the story, all but the Death of Rats and Death of Fleas were reabsorbed into one Death. It's strongly implied in the same work, however, that the Death we know only covers the Discworld; other Deaths exist in other places, and all are aspects of Azrael, the Death of the Universe.)
Saint Vidicon of Cathode in the Warlock of Gramarye series by Christopher Stasheff. The patron saint of technicians and engineers. Saint Vidicon's symbol is a yellow screwdriver worn in the shirt pocket. In a later book, his history was revealed - he was martyred when he used his body to close an electrical circuit, allowing a speech by the Pope to make it to air and save the Catholic Church from obsolescence.
"Blessed Saint Vidicon, defend us from Murphy!"
L. Sprague de Camp's short story "The Hardwood Pile" features Aceria, the one of the Tree Nymphs of Norway Maples. After all the Norway Maples in the area are cut down she becomes the Nymph of Piles of Wooden Boards that Used to Be Norway Maples. At the end of the story she becomes the Nymph of Nightclub Dance Floors Made of Wood From Norway Maples.
The Bastard from the Chalion series. The only god not associated with a season, his domain is all things out of place: demons, children born out of wedlock (obviously), odd loves, disasters, and unorthodox justice. He also takes the souls of those not devoted to any of the other gods.
In the Forgotten Realms crossover Finder's Bane, a god residing outside the Realms (which has, or used to have, Loads And Loads Of Gods) comments that "We wouldn't be surprised to find they have a god there with dominion over the tableware and ale mugs."
Tortall Universe: Tamora Pierce's series of books set in universe has the big gods, like Mithros (war and justice), and the Goddess (fertility, women, agriculture), but it also has minor gods like Weiryn (god of the hunt for a small mountainous area), and rather hilariously a god of crossroads.
Glen Cook's Garrett, P.I., while he doesn't believe in gods until he's actually hired by some of them, is a Deadpan Snarker with a personal Running Gag about how the Butt Monkey Odd Job godling who passes out towels in the heavenly loo has a secondary job: messing with Garrett's life.
He's also hypothesized that the reason so many shady people in TunFaire have really stupid nicknames is that some mentally-challenged microdeity thinks it's a hoot to slip ideas for them into people's heads while they're squatting over a chamber pot.
In Journey to the West, Son Wukong (who regularly trounces the gods in hand-to-hand combat) gets the job of Celestial Stable Boy to placate his ambitions, but that just ends up kicking off an even worse Rage Against the Heavens. (It does end up being a useful item in his resume later on, though, as all horses, regular and supernatural, hold him in awe as a result.)
The Liavek anthologies had Bree Amal, Goddess of Keepers of Disorderly Houses, and Ghologhosh, god of unmeant curses.
Split Heirs by Lawrence Watt-Evans give us a God of Misused Things. Which might be extremely influential nowadays.
Mentioned in passing to convey Aerin's experience climbing the apparently perpetual tower to the Final Boss Battle toward the end of The Hero and the Crown; she concludes she has been climbing forever, and will be climbing forever, and might become a sort of minor god, the God Who Climbs, comparable apparently to the 'God Who Isn't There,' which is the shadow god at noon.
Lord Dunsany's The Gods of Pegana includes many of these; indeed, nearly the entire Pegana pantheon qualifies!
"These be the gods of the hearth: Pitsu, who stroketh the cat; Hobit who calms the dog; and Habaniah, the lord of glowing embers; and little Zumbiboo, the lord of dust; and old Gribaun, who sits in the heart of the fire to turn the wood to ash — all these be home gods, and live not in Pegana and be lesser than Roon."
In the Rainbow Magic series, pretty much every fairy is this. There are fairies responsible for colors and the weather, as well as princesses, parties, the days of the week, sports, and fashion, among many others.
The Gentleman Bastard series takes place in a world with twelve gods (thirteen if you count the heretical god of thieves) with flourished and sometimes funny titles. For example, Gandolo the god of trade is also known as the "Heavenly Father of Business Transactions", and the god of thieves (simply known as the Nameless Thirteenth) is nicknamed the "Father of Necessary Pretexts".
In The Thousand Names, the leaders of the Redemption rename themselves after various angels. The leader of their military idly wonders what would happen when they ran out of angels with impressive portfolios like Vengeance and Victory and have to start using the names of lesser angels like the Angel of Sisterly Affection or the Angel of Small Crafts.
In the first episode of Rome, Titus Pulio is locked up in a cell and prays to Forculus to release him. Forculus is related to Janus, the god of gates and doors, though the DVD commentary notes he should have prayed to Cardea as well, the god of hinges.
Phil, the Prince of Insufficient Light, the ruler of Lower Heck. He punishes people (usually Dilbert) for minor infractions not worthy of damnation in hell, such as using copier paper for the printer or stealing a chair from another cubicle.
Thor appears to Dogbert offering him a job as one of these, promising further career advancement (Thor himself claims to have started out as the God of Static Cling). Dogbert then accepts the position of "God of Velcro". And he signed Dilbert up for the God of Mayonnaise.
Stand Up Comedy
Eddie Izzard did a bit about the influence of the Greek gods on the Romans, saying that originally the Romans had rather crap gods such as Jeff the God of Biscuits, and Simon the God of Hairdos.
In Nomine: Steve Jackson Games' English language version had a number of demons and angels with rather odd Words (areas of influence), and the rulebook gives a GM the ability to assign these to players. Some examples:
Caliban, the Demon of Anorexia
Maigonigal, the Demon of Bad Art
Tomas, the Angel of Catchy Tunes
Zuheyr, the Angel of Cleanliness
Connor, the Angel of Cooking
Randolph, the Angel of Dictionaries
Fleurity, the Demon Prince of Drugs
Stander, the Demon of Embalming
Karne, the Demon of Fast Food
Imbap, the Demon of Stale Bong Water, who serves as an object lesson to Demons: Don't pester Lucifer for a Word because he may just give you one.
In the tabletop RPG Exalted, everything has a god. Everything. From concepts like love, taxes, and urban metropolises, to physical places and objects like crop fields and even individual rocks. Generally speaking, gods of concepts and abstracts outrank those of concrete things and places. Gods of thing smaller than say, a large building, tend to not be sentient.
The god Nara-O of the Hundred Veils would seem to be this, since his official purview is "Secrets Known to Only One Person". However, this practically means that he's the god of all private (and often lost and forgotten) information. Nara-O is probably personally and politically one of the top ten most powerful gods in Heaven.
One artifact from a splatbook is a prayer stone keyed to one specific goddess, whose entire purpose is to receive and relay messages made on this stone. She is immensely reliable because she's that desperate to have something to do. Not to mention that the stone has been lost since the Golden Age, making for one terminally bored goddess.
Heaven also contains literal odd job gods, being people who are only good for basic paperwork, filing and message carrying.
There's also Zuggtmoy, who isn't truly a real goddess, but a demon lord with dominance over fungus... Which is the whole problem. She has a very hard time attracting worshippers, because there isn't much she can offer mortals. This has caused her to make foolish mistakes which have let far more powerful evil gods like Tharizdun take advantage of her in her attempts to gain power. Without a doubt, the biggest threat that was caused because of this was The Temple of Elemental Evil, an adventure that was ranked the 4th greatest of all time by Dungeon magazine in 2004, on the 30th anniversary of the Dungeons & Dragons game. (Still doesn't change the fact that the ending turned out very bad for Zuggtmoy.)
Technically, Mystara has Immortals rather than gods. Lots and lots of Immortals, some of which would think "god of insects" was the big time.
In Paizo Publishing's D&D 3.5-edition retro-clone game Pathfinder meta-setting:
Alseta, goddess of doorways.
Ghlaunder, god of insects and parasites.
Zarongel, goblin god of dog-killing, fire, and mounted combat.
In the Warhammer Fantasy universe, there's Necoho, the god of atheism. He gets more powerful as he loses followers.
Warhammer 40,000 has the two ork gods Mork (who is cunningly brutal) and Gork (who is brutally cunning). Or was it the other way around?
This is sort of the whole point of Nobilis, where your character is essentially one of these. Your character might literally be the Power of Friendship. On the other hand, she might also be the Power of Lipton Instant Noodles (an example from the book). The difference in power and prestige between these is less than one might think- or may not necessarily even go in the direction one might think.
Magic: The Gathering: In the Kamigawa block, the short version of the story is that the Gods are pissed, and out of bubblegum. The set's flavor was influenced by Shinto, so there are Kami for everything, from Cleansing Fire and Infinite Rage to... Pus and Painted Roads.
The Primal Order, by Wizards of the Coast, is a sourcebook ideas and rules on how to handle deity-level action in fantasy games. Their two 'official' example deities? The Hawaiian goddess Pele and Joey, God of Basketweaving.
Gilbert and Sullivan's very first show together, Thespis, plays Mercury (a.k.a. Hermes) this way. In fact, he does pretty much everything, with the other gods sitting around and taking the credit.
The Elder Gods of Lusternia were divided into seven pantheons which dictated their roles. However, some Gods were massively more important in their pantheons than others. After all, what sounds more impressive - the Seventh Circle creator who birthed the noble race of stags, or the Seventh Circle creator responsible for the genesis of fleas?
Well, fleas were the bringers of the Black Death...
Not to be confused with his brother Tsun, the god of "trials against adversity". But don't underestimate him - dead warriors can't go to Sovngarde unless they defeat him in a duel. And in Skyrim, this is part of the main storyline.
The Daedric Princes offer a fairly true to life take on the randomness of gods. Most notably, there is Peryite the Taskmaster, viewed by some as the weakest of the Princes, whose sphere is pestilence, but also the ordering of the lowest orders of Oblivion.
Most of the gods of City of Heroes are pretty powerful, but that doesn't stop a djinn from existing solely to keep an eye on four enchanted mantles or prevent a wide array of quickly forgotten gods from running around. Trapdoor is essentially the god of running away, and the Furies are exactly what you'd expect. Lord Recluse seems to be the god of spiders, while Statesman seems to be the God of Superheroes.
In the Disgaea series, any item can be entered like a dungeon; (this is called an Item World.) If that item has a "legendary" trait; then this Item World is 100 levels deep. It has generals, kings, and at the end of level 100; an item god. You are encouraged to go through these and kill them all; as it powers that item up for you. So you can kill the Item God of a sword, piece of armor, used piece of chewing gum, detached horse penis...
Ōkami features gods of assorted elements, rejuvenation, explosions, cutting, the Sun and Moon, and Kabegami, the god of walls. The game is based on Shinto, which has rather a lot of gods. When one wishes to refer to all of the Shinto gods collectively in Japanese, one speaks of "the eight million gods".note And that's not a strict limit, either. "Eight million" is an archaic Japanese euphemism for "a vast, possibly infinite number", the same way forty is used in the Bible.
Shin Megami Tensei games features numerous Odd Job Gods as regular encounters and occasionally boss fights. Special mention goes out to Shin Megami Tensei: Strange Journey, with Kanbari, the god of toilets. Devil Summoner: Raidou Kuzunoha vs. King Abaddon has more than a few of its own; early on, you get cursed with bad luck, and are assaulted by Binbou-gami, the god of poverty, who takes the form of a man hanging upside-down from a cloud raining coins from his shirt. Most of his attacks involve giant coins landing on top of you, too. Other strange gods include the above-mentioned Pele and fellow Hawaiian deity Kamapua'a (a hog-man), and Taoist god Neko Shogun.
Others include, but are not limited to: Kudan, a human-headed cow that is born to issue a single prophecy of disaster and then dies, the Hare of Inaba, who was skinned for his insolence, Mamedanuki, a sort of raccoon dog capable of transforming its scrotum into useful objects, and hell, even the friggin' Chupacabra.
Jade Empire features a Celestial Bureaucracy that tracks the actions of the heroes. At one point, a god appears to you and chews you out for wreaking so much destruction; his job was to tabulate your karma, and he was so ill-suited for the task he was demoted. So now he sells you trinkets.
The procedurally generated deities of Dwarf Fortress sometimes fall into this. The game may, for instance, generate a god of salt. Sometimes these deities can get Flight, Strength, Heart as well; it's perfectly plausible to find a god of death, war, murder and... rainbows.
RuneScape has Brassica Prime, the cabbage god of cabbages.
The fal'Cie of Final Fantasy XIII. Sure, you had fal'Cie who did important things like producing food or acting as the sun. But some fal'Cie had less important tasks like... operating automatic doors.
In Dungeons of Dredmor, you can get a Side Quest to earn a random piece of magic equipment by praying to Inconsequentia, Goddess of Pointless Sidequests. You can also leave offerings of lutefisk to shrines of the Lutefisk God, who will offer a magic item if you bring him enough.
Kingdom of Loathing has a mini-boss in the Hidden Temple, the half-serpent, half-sheep deity Baa'baa'bu'ran, who according to his Monster Manuel entry is the god of doorknobs, the smell of rain, open-faced sandwiches, and the ampersand. Also, one of the Pokemon-esque gods whose altar you find in the Hidden City is Squirtlcthulli, god of water and doorknobs. There was also an event that involved a player finding the name of the Demon Lord of Fruity Girl Drinks and summoning him for the first time.
The citizens of Santa Destroy in No More Heroes recognize gods of each side job in the game, so you have gods of coconuts, cats, garbage, steak and scorpions, the last of which can apparently be slain by killing scorpions.
In Irregular Webcomic! there is a separate Death for every way anybody has ever died, including such infrequent events as Death of Choking On A Giant Frog and Death of Being Ground By A Mars Rover Rock Abrasion Tool. The less-likely Deaths are desperate for promotion.
In Snowflame, our protagonist worships the Goddess of Cocaine.
The Order of the Stick has Giggles, god of slapstick. He's worshiped exclusively by a tribe of orcs on a small island, and was made up by Elan. Who is the world's only worshiper of Banjo, god of puppets. Although they're officially brothers, so Banjo may enter the orcish pantheon as well.
They were actually Banjo worshippers initially, but Giggles was a better fit for their spiritual needs.
Uncle Time from Sluggy Freelance is in charge of governing the timestream in Timeless Space, which, as its name suggests, doesn't have a timestream. What he does all day besides knocking the occasional mini-lop rabbit through dimensions is unclear.
The Gods Of Arr Kelaan has Ronson, the God of Apathy and Beer, as well as Shadowscared, God of being afraid. Despite this Ronson is the head of the traveler pantheon.
In 8-Bit Theater, Red Mage says that if they're lucky, they'll deal with what he calls "the wussy demons," meaning "The usual stuff: pain, darkness, anger..." When Black Mage asks what he thinks the "Hardcore," demons are, he replies "demons relating to urine or bad haircuts." While Black Mage is obviously skeptical, Red Mage proves him wrong.
Squid Fairy from Imminent Moose has the power to grant any wish... as long as it pertains to squids.
Nodwick featured a lot of oddball deities. In one story, a Goddess of Peeping Toms appeared. (Who was, ironically, very often the victim of them.)
The Divine Census of Cedrism includes such oddities as B'Caw, God of Spicy Chicken, and Mog, God of Political Blunders. Even the relatively normal gods have bizarre sides (the god of warriors and soldiers is also the patron god of "guys with long hair")
In the french site of ASP explorer, in a series of short stories parodying the adventures of Conan the Barbarian, we are introduced to a newly ascended goddess :
"Mranis actually was a rather careless deity. In front of Divine Agora, summoned to choose her divine attributes, symbols and titles, as it is the custom for the gods, she had chosen, to her peers great consternation, the Small Burin of the Patient Excavations, the Half Extincy Torch of Dark Illuminations, her red and black half skinned cat named "Touminou", and her complete name was written, as the custom wants, on the titanic porphyre steps of the Great Cenotaph: "Mranis, funny little goddess of violence, destruction, sex, scientific research and the other funny stuff ". Mesculias, god of chance and destiny, bet two major temples and twelve thousand minions against a mouldy baguette that she never would find any believers with such a manifest. Nobody among heavenly assembly raised the bet."
In the Earthworm Jim episode "Assault and Battery", Jim goes to the Fabled, Long-Sought Home of the Gods to receive a new battery for his supersuit. There, he meets the gods of nasal discharge and puns, and the goddess of disco, who explain that the biggies are at a party in Valhalla.
On Sam & Max: Freelance Police, after the titular duo get Zeus and Juno back together in the episode "Dysfunction of the Gods", they are rewarded by becoming the God of Junk Food and the God of Vulgar Novelty Items respectively.
One of the most powerful characters in The Tick is The Mighty Agrippa, Roman God of the Aqueduct. According to the series canon, he's the last god to join the Roman Pantheon; but when he showed up the rest had left for another planet. Despite being a low-ranking god, he's still a Physical God and one of the strongest beings in the series.
Qadesh, the goddess of (sexual) ecstasy. (Originally a Syrian fertility goddess.)
Ancient Rome called them lares, and most houses had a small shrine called a lararium. For ordinary Romans, they were typically the most important gods as they were most commonly involved. After all, you don't to bother Jupiter Optimus Maximus when cooking dinner.
Mike Judge didn't make up the Sterculius character mentioned in Western Animation. There really was a Roman god called Sterquilinus who was God of Manure.
Cloacina, god of sewers; goddesses of doorways/hinges, menstruation and weeding and rust. Good story here: Cloacina was the goddess of a stream that ran through where Rome is now. Eventually, this stream was paved over and made into the sewer. As a sort of apology and thanks to her, there were lots of little shrines to Cloacina; eventually, she became the general goddess of sewers.
Just about every step of agricultural production had its own minor god: Sator for sowing, Messor for harvesting, Conditor for storing the harvested grain, etc.
Catholicism has a long tradition of appointing Patron Saints with job descriptions often based on what they did in real life. It should be pointed out that saints are not gods and are not worshipped by mainstream Catholics but in some cultures local deities have been known to assume the personality of saints, and vice versa.
St. Clare of Assisi, the Patron Saint of Television.
St. Nicholas is the patron saint of basically everyone. (The list includes children, sailors, fishermen, merchants, the falsely accused, prostitutes, repentant thieves, pharmacists, archers, and pawnbrokers). This is quite probably the main reason that his story was used to create Santa Claus.
Mother Frances Xavier Cabrini, the first U.S. citizen to be canonized (a New Yorker, natch) is, according to this humorous site, "official" patron saint of parking spaces. However, St. Therese of Lisieux is listed as a rival there, and this site lists yet others.
The Catholic Church has a habit of adding to a popular saint's portfolio if they could justify the connection. Thus, you have St. Joseph (Jesus' adopted dad) being the patron saint of fathers and social justice (among others), St. Matthew (writer of the first book of the New Testament and a former tax collector) being the patron saint of tax collectors and stock brokers, St. Isidore of Seville (he wrote an encyclopedia in the seventh century) now patron saint of computers and the Internetnote Not "officially" (the Holy See has not spoken on the issue), but he was voted as such in an Italian poll and St. Thomas Aquinas (noted Catholic theologian) standing for learning but somehow against lightning.
St. Jude (mentioned in the bible as "the apostle called Jude who was NOT Iscariot") who is, by this sad naming coincidence, now the patron saint of hopeless causes (as people were afraid to pray to him for fear of it being interpreted as a prayer to Judas who was Iscariot).
St. Anthony, the patron saint of finding lost things.
The winner of this unfortunate competition is probably St. Drogo, patron saint of bodily ills, broken bones, hernias, sick people, insane people, ugly people, orphans, shepherds and coffee shop owners. No, we're not making that one up.
In fact, the syncretistic aspect of the Catholic Church's patron saints is what made Vodun and Santeria possible as viable religions — by equating their native pantheon with the saints of the Church, it was possible for Caribbean slaves to keep aspects of their native religions alive in the New World with minimal risk of reprisal from slaveholders.
Not a saint recognized by the Catholic Church, but Jesús Malverde is known as the patron saint of drug trafficking.
A joke has named St. Chad a patron saint of disputed elections.
The Russian Orthodox Church has patron saints of nuclear missiles, strategic bombers and other weapons of mass destruction.
St. Barbara is the heavenly patron of the Strategic Missile Forces of Russia.
Much older tradition. St. Barbara has been recognized as the patron saint of artillery, fireworks, and other gunpowder objects since the invention of the European gunpowder, in Catholicism as well as in Orthodoxy. Indeed, she is also the heavenly patron of U.S. Army and Marine artillery as well as artillery arms of many other countries.
Admiral Fyodor Ushakov (an actual admiral who was canonized by the Russian Orthodox Church) is the patron saint of long-range nuclear bombers.
And St. Seraphim of Sarov is the patron of all Russian nukes, both tactical and strategic.
Shinto believes that essentially all items have a spirit or god (This translates better as spirit than god).
Shinto deity Inari - god of fertility, industry, success, agriculture, rice and foxes. He was the patron kami of blacksmiths and warriors - currently accepted by the cosmetics company Shiseido as their patron kami. He's an all-round god.Shin Megami Tensei loves this fact. All the gods listed under their entries in Video Games? Real.
Aztec Mythology had a few gods like this. One quite unusual assortment included vanity, fog, and fame, ruled over by Ayauhteotl.
the god of ovens, who has the secondary job of spying on the household to report good and bad deeds (and would thus have to be bribed often with sweeties to keep his mouth shut). This is the Chinese kitchen god made well-known in the West through several literary works (such as the Amy Tan novel, Kitchen God's Wife) and other media. He is somewhat of a Santa Claus figure, as he is supposed to bring gifts for good families (or good children) on the night before Chinese New Year's Day.
the god(s) of doorways, occasionally said to be the spirits of ancient fearsome warriors. Specifically, the tradition started with two famous generals of the Tang Dynasty, Weichi Jingde and Qin Qiong, who served as physical gate guardians for Emperor Taizong. Supposedly, when the actual generals could not serve as the guardians for whatever reason, the emperor put up their pictures instead, which started the tradition.
Guan Yu, the God of War, legendary hero, protector of all of China, champion against demons, and once one of the most popular gods among all the classes. He is also the patron god of bean curd (tofu) since before he became a warrior he was a bean curd merchant. It's more important than it sounds since bean curd has traditionally been an important food in China.
Wenchang, Taoist god of literature, writing, and education- and the god you pray to for help passing your exams. Given the importance of the imperial examinations- which determined who got a government job and basically were the only means of social mobility most of the time- it's not that surprising that there was a specific god for it. (In modern times, scallions seem to be a popular offering.)
The god of rice scoops is often cited as an example of extremely minor and extremely unimportant Chinese deities.
Pre-islamic Arabia had Wadd, a god of snakes, the Moon and friendship.
The Greeks liked to append random attributes to Apollo, which eventually made him god of "light and the sun; truth and prophecy; medicine, healing, and plague; music, poetry, and the arts; and more" according to Wikipedia.
Hermes was nearly as versatile, being god of messengers, travelers, merchants, thieves, sports, commerce, shepherds, and weights and measures.
Most of the major gods get in on the action; Zeus, for instance, besides being King of the Gods and god of the sky, was also called Zeus Xenios, the patron of Sacred Hospitality, while Hades served as a god of wealth (hence the Roman name Pluto). It made sense because as the god of the Underworld, all the riches found underground (gemstones and precious metals) were said to belong to him.
There's also Dionysius, God of Wine and Parties. The wine part makes a bit more sense when you realise how much more common a drink it was back then.
A legend has Artemis sitting at Daddy's knee asking for three wishes, one of which was to never be outdone by her twin. Zeus was supposedly delighted by her wishes and granted them all, which might explain why she became goddess of wild animals and hunting, wilderness in general, the moon (eventually), young women, chastity, painless childbirth (due to circumstances of the twins' birth), etc.
