Mister Seahorses in fanfiction.

Because Most Fanfic Writers Are Female that love playing around with even the faintest of Homosexual Subtext, this trope (often categorized as "mpreg") is quite prevalent in fanfiction. Many writers will justify it by making the male character a hermaphrodite, a trans man, or applying some weird Phlebotinum or magic, while many will simply hand wave the whole thing. More often than not, it's merely a perverted excuse to depict male characters with big bellies.

There is also the relatively new phenomenon of Alpha/Beta/Omega dynamics, also called ABO or A/B/O, AO, Knottingverse, or Omegaverse. There's some dubious biology involved, at least when the fics don't go headlong into speculative Bizarre Alien Sexes territory. It originated in the Supernatural fandom when mpreg and werewolves were combined. This is the unholy spawn, which has since slowly spread to other fandoms, though it still represents a miniscule amount of the total fic produced. Mostly, it's an excuse for mpreg.

    Fanfiction based on Anime & Manga 
  • Axis Powers Hetalia fanfics Hakkōna and Kaitō Kokoro: Within both stories, male Obake can impregnate other male Obake, perhaps because they could technically materialize the necessary organs and synthesize the necessary hormones. This is how Kiku and Feliciano had their own children.
  • In the Hellsing fanfic The Way To An Heir, Alucard attempts to impregnate Integra with a spell, but ends up getting himself pregnant. While somewhat bizarre, it actually makes sense (Girlycard duh!)
  • Only slightly less disturbing are slash fics that use male pregnancy as a natural consequence of gay sex.
  • In the Mobile Suit Gundam Wing fandom:
    • This happens so often to poor Duo Maxwell that you could probably find such a fic in five random searches.
    • Heero is popular too, by rape at times, since he was experimented on and all.
    • Quatre sometimes gets pregnant too.
  • Mpreg is very popular in Axis Powers Hetalia, as states and provinces are often depicted as the children of nations. However, if you applied a bit of Fridge Logic to this, you would realize that a country's states are actually parts of their physical body, such as America's ahoge as Nantucket, and Korea's as Seoul, so the entire premise is built upon the MST3K Mantra.
    • Except that the countries are all anthropomorphic personifications, so literal "body parts equated to country geography" doesn't really work.
    • Poor America seems to suffer the most from this, with a entire livejournal community dedicated to his pregnancies. Such is the popularity of giving America the seahorse treatment that someone actually did a chart detailing the most likely fathers of the respective states with comments on the circumstances of their conception (for instance, Alaska is "Most likely to have resulted from hate-sex").
    • There is the canon presence of Hong Kong, a city in China, who's sometimes taken by the fandom to be China and England's love child. And Cyprus, another official (if yet-to-appear-in-canon) character, is often similarly viewed as Turkey and Greece's love/hate child.
    • The premise of Blue Blanket revolves around Sealand being England's Child by Rape. If you're wondering who the other father is, it's Germany.
  • The Yu Yu Hakusho fanfic Cockroach by Thoth Moon is a deconstruction of this trope. It features Sensui and Itsuki, the last two guys in YYH who should be having a baby and is presented as a very scary Body Horror story, with What Measure Is a Non-Human? added for good measure because of the characters involved. After numerous failed abortion attempts, Itsuki gives birth through a very painful dimensional rift between his legs. So painful, in fact, that he passes out for a few hours during labor in the bathtub. They end up keeping the dead baby in their freezer after Sensui's "Kazuya" personality slaughters it.
  • Fruits Basket slash authors love doing this to Hatori, who transforms into a seahorse if hugged by a woman.
  • A popular element of Pet Shop of Horrors fanfiction. Guaranteed to be a FOURTH of the total fanfics available of this fandom. Possibly justified with Count D, as he is not human... But Leon?!
  • There are a lot of Dragon Ball Z fanfics that have either Goku or Vegeta pregnant with each other's baby. It's become widely believed by fans that male Saiyans are capable of impregnating each other, though opinions are split on whether this applies to all male Saiyans or only the "lower-tier" ones.
  • There's a XxxHOLiC fanfiction that can be found here that has Doumeki getting pregnant after eating a magic donut. Hilarity Ensues.
  • Poor, poor Edward Elric. So many fanfics have this already-traumatized Child Soldier get pregnant and suffer Badass Decay every time he turns around. The other father is most commonly his commanding officer who is fourteen years older than him, except for that time Envy was the "mom."
  • In the Naruto fandom:
    • Naruto would get impregnated (usually because of Sasuke) because of several reasons; the Kyuubi is a female (even though it is just a mass of malevolent chakra with no real gender), the "fact" that demons can reproduce regardless of gender and this was carried on into Naruto (or other jinchuuriki like Gaara, opening up a whole new can of worms), there is a jutsu that enables males to get pregnant, Sexy no Jutsu somehow alters the user's entire biology, or Orochimaru is being his usual sick self and experimented on male pregnancies for some completely unknown reason. Take your pick.
      • Beyond all this, it somewhat ties into kitsune behaviour, as they were known to pull such shenanigans.
    • In the rare chance that Sasuke gets pregnant (in the NaruSasu pairings) it's usually because of the Kyuubi's chakra that causes his pregnancy. That or Orochimaru/Kabuto did some rather interesting experiments on poor Sasuke, leading him impregnated by everyone and anyone, including his own brother. Occasionally it's Sexy no Jutsu gone wrong, but since he has the Sharingan wouldn't he just be able to perfectly copy the jutsu?
    • The second part of Sasuke's goal is to repopulate the Uchiha clan... but in Self Reliance (Original story deleted, archived version in HTML and PDF format available), he doesn't trust any females he knows to carry his child. So he decides the logical course of action is to carry the child himself.
    • Kyuubi the Btch is a deconstruction of the biological aspects of stereotypical MPREG stories. You want to know what happens when a pubescent boy spontaneously develops a functional uterus without a vagina? He menstruates, and the pressure relieves itself by punching a hole in his rectum.
  • The Assassination Classroom fanfic There Is No Sweeter Innocence Than Our Gentle Sin focuses on a pregnant-by-Karma Nagisa, with the pregnancy being written surprisingly realistic for an mpreg fic.
  • This Fairy Tail fanfic, which manages to keep everyone in character for roughly three chapters before slowly derailing (though one character does have a justified, plot relevant character change).
  • There's a Suzumiya Haruhi No Yuutsu fic which involves a rare heterosexual version. What happens when a couple wants a kid, but the girl doesn't want to carry a baby? Usually, adoption or nothing. However, when said girl is a Reality Warper...
  • This video features a couple of fangirls trying to get Johnny Yong Bosch to sign Bleach M-preg fanart.
  • This Bleach Mpreg fic actually does some rationalizing... a bit. The author fully admits that it isn't really good science but that it works for her. She then takes it Up to Eleven by having the character give birth... in enemy territory.
  • Parodied in the Code Geass fanfic Ambiguous wherein Suzaku mysteriously gets pregnant by Lelouch. The natural way. The biological impossibility of this is lampshaded, amongst other improbabilities found in Mpreg fanfics such as the credibility of the doctor to reach such a conclusion, and male seahorses.
  • Done many times in Yu-Gi-Oh! GX Fanfic. Usually justified by Jaden/Judai's fusion with Yubel granting him (some of) the necessary equipment.
  • There is an entire Tumblr dedicated to the idea that Vash and Knives get pregnant by Wolfwood and Legato, respectively (with the resulting offspring having their own RP blogs). It's explained that since Vash and Knives are plants they're not "male" in the truest sense of the word.
  • In Evangelion fanfic "A New Life", it's heavily implied Asuka got Shinji knocked up during the time they spent gender-swapped and he was the one actually delivered their daughter Yui.
  • There are many, many Yuri!!! on Ice fanfics involving Yuuri bearing Viktor’s children, most popularly mixed-gender twins. Them being the Official Couple doesn’t hurt. Oh, and most of it is Omegaverse.
  • ''Your Best Kept Secret And Your Biggest Mistake'', a My Hero Academia Todoroki/Midoriya Transplanted Character Fic, is one of the better examples from that fandom, with many readers commenting how much they enjoy the story despite usually hating this trope. It helps that it's not Omegaverse, unlike most other examples in that fandom.
  • The JoJo's Bizarre Adventure Doujinshi JoJo's Bizarre Married Life aka CLAMP in Wonderland is notorious for having Kakyoin lay an egg that hatches into his and Jotaro's child.
    Fanfiction based on Comic Books 
  • Based on a Mighty Avengers arc where Tony Stark was turned into a woman temporarily; a mpreg fic called Moth has been written.
  • A decent Affectionate Parody of the genre is That Damn MPreg.
    • It features the Young Avengers characters Wiccan and Hulkling. Oddly enough, these two characters are relatively easy to explain away in terms of an MPreg: Hulkling is a shapeshifter, and Wiccan can alter reality in a limited fashion (by way of example, the character who he is based off of, Scarlet Witch, got pregnant off a robot, which is on a level of insanity equal to MPreg).
      • Actually, Wiccan has been revealed to be the lost son of the Scarlet Witch, as is Speed, so he has similar powers to his mother, like his twin has similar powers to their uncle.
    • The universe also has Grace Summers, the daughter of Sean Cassidy-Guthrie and Christian Summers. Carried to term by Christian though the circumstances regarding what allowed the pregnancy remains a mystery.
  • In the Superman fan fic Superman Starts family, a female-to-male transgender Superman gets pregnant after being sexually assaulted by Lex Luthor. Superman looks through the rubble of a destroyed building for survivors and then battles Darkseid while twenty-seven weeks pregnant. What makes Superman extra ferocious when fighting Darkseid is that Darkseid had children as hostages.
  • The two-part fic, X-Men: Saber tooth Mpreg, puts an interesting spin on the genre. Unlike most other Mpreg fics, the characters aren’t turned into Out of Character woobies or softies, and the story is far from your typical fluffy kid fic.
    Fanfiction based on Film 
    Fanfiction based on Literature 
  • Harry Potter fanfic writers love this to death. At least the unpredictably of magic gives it a fair reason/excuse. Most of the time. It's perfectly common to see Harry knocked up with twins, usually, from Draco or Snape, or anyone really.
    • A Snape/Lupin mpreg story can be read here. It's not a slash story and surprisingly well written, despite the first chapter being a bit OOC.
    • There was a Harry Potter fanfiction in which Ron and Draco had a fertility potion spilled on them during a private detention in Snape's dungeon, leading to Ron becoming pregnant by Draco, who left him, so Ron ran off to have sex with Harry, who dumped him after finding out Ron had slept with Draco; then Ron started going out with Gary Stu!Neville, who just so happened to have a crush on Blaise, leading to Ron and Neville making out in front of Blaise and Draco in order to make them jealous, which preceded Neville finding out about Ron's pregnancy and declaring that he wanted to be the baby's father, while Mentor!Snape helped them along. There wasn't a female character in the fic.
    • There is a fanfic where Harry gives birth to a kitten, after having gay sex with Voldemort while transmuted. Couldn't make this up if I tried, people.
    • This script fic parodies nearly every Harry Potter Mpreg fic ever.
    • My Immortal unintentionally references this in the line where Harry fends off two peeping toms by yelling "ABRA KEDAVRA!" and "pointing his womb".
    • A Most Unlikely Family is a Harry Potter-Discworld crossover, in which Neville finds himself in Ankh-Morpork, pregnant with Harry's baby. Apparently the magical accident responsible gave him a womb but not a vagina.note  Sadly the mother didn't survive, but here's something to ponder: which Discworld character kinda resembles both Harry and Neville?
    • There is also Rise Of The Drackens, where Harry gets pregnant several times with many babies, carrying five at the most, and his mood swings get very high. The fathers are his four lovers, who are male Drackens.
    • The entire premise behind Deserving.
  • The Lord of the Rings:
    • The creators of Bag Enders are also known for comedic mpreg, and described it thus in their "Horrifically Honest Guide to Fanfiction Terms": "Since there exists no fanfic genre of ‘M-PMT’ or ‘M-bloody awful period pain’, this is one outlet to make your characters get all the suffering of being female with none of the benefits. Bwahahaahahaa!"
    • Feel free to alternate between cringing and cracking up while reading the ultimate Legolas/Aragorn. "My assumption is correct: your birth canal has formed." NO. WORDS.
    • While most Frodo-slash stories have Frodo be the one who gets pregnant, The Depths of Love mixes things up by makes SAM the "mother".
  • One Redwall fanfic unintentionally references this. The Mary Sue heroine's sidekick was supposedly the daughter of the canon characters Brome and Keyla. Brome is a male mouse, and Keyla, despite the Gender-Blender Name, is a male otter. As they didn't appear in the fic, one can only assume the author forgot the gender and/or species of at least one of them, but the mental image wasn't fun.
  • In The Hobbit fanfic series A Hobbit's Hole (er I mean SMIAL!), male Fallohide hobbits are capable of getting pregnant. Bilbo is one such hobbit, and over the course of the series he becomes pregnant by Thorin and gives birth to Frodo and his Original Character siblings Frerin and Jewel.
    Fanfiction based on Live-Action TV 
  • This Star Trek: Voyager fanfic is a classic parody of mpreg fanfic cliches.
  • A number of Heroes fanfics feature Mohinder giving birth to Sylar's baby. This is normally justified by the good doctor's experimentation with a defective Super Serum. In an alternate future, the formula transformed him into some sort of bug mutant, so who's to guess what all else it might have done to him. Though, one has to imagine it could just as easily be written the other way around since Sylar is a shapeshifter.
  • I've Heard Nothing If It Wasn't the Wind, an Alternate Universe CSI: NY fanfic that treats the trope as horror and features Danny as Mister Seahorse and Mac as the father, sort of (via a vengeful and very nasty demon).
  • There is an Andromeda fic (NSFW) where Tyr finds himself a highly evolved lover who cannot have children due to her body rejecting the sperm. So, her eggs are implanted into Tyr (no operation - a subconscious desire come true). Her nanobots even rebuild him so he gives birth the natural way.
  • There's a House fanfic that fits the trope, with a crackfic-ish inspiration. Read it here.
  • Star Trek: The Original Series slash writers are fond of this trope, often utilizing Spock's alien-human hybrid status or random alien-induced mutations as a justification for some truly bizarre biology.
  • Star Trek: Deep Space Nine
    • For Freedom's Sake has Odo conceive through BizarreAlienBiology. Actually pretty well thought out, because it was the baby Changeling from the canon episode The Begotten. As it changed Odo back into a Changeling, it integrated into his body using his morphogenic matrix and biomolecular structure to rebuild itself, thus making Odo its new progenitor.
  • Doctor Who:
    • There are a couple of fairly squicky Doctor/Master slash fics involving the Master (usually in a position of some power) forcibly impregnating the Doctor through magic Time Lord science. Whilst these rarely raise the question of why he would make the Doctor carry a fetus to term only to have to surgically remove it, some are well-characterized enough to point out that the Master is bat-shit insane. Here it is.
  • This trope has finally, officially reared its ugly head in the Big Bang Theory fandom with this charming little tale. If you can't face it, but are still curious as to who the victim is: It's Sheldon.
  • It's not exactly surprising that Torchwood fanfic authors latched onto Jack's throwaway line "Well, at least I won't get pregnant. Never doing that again," while talking about oestrogen in the rain from contraceptives getting in the water supply. And considering that he's from the 51st century, this is less ridiculous than in most fandoms.
    • Despite that, it's still more common for fanfic writers to make Ianto the pregnant one.
  • It happens in the Merlin/Arthur-ridden Merlin fandom, and is parodied in Caught in a Slash.
    Arthur: "You think that my male manservant is PREGNANT?"
    Gaius: "Yes, Sire."
And when Gaius reveals that there's something worse
Gaius: "It's yours, Sire."
Arthur is understandably horrified... Considering that they've never had sex.
  • An extremely long American Idol fanfic titled Cambios narrates the entire life chronicles of David Cook and David Archuleta's kids, beginning with their daughter Reyna who was conceived accidentally during their time at AI (meaning Archie was 16, people!), with very little explanation (something about some guys being able to get pregnant). The two go on to have four more children, and Archie looks 'exactly the same' a decade later. It ends with Reyna auditioning for American Idol, and the judges proceed to tell her that she looks like both Archie and Cook, and her singing voice is a mixture of the two.
  • Very common in the Glee fandom with Kurt/Blaine shippers. Finn supposedly utters the line 'don't get my baby brother pregnant' a lot.
  • Numerous Sherlock fanfics. Usually Sherlock/John. By far the weirdest one is this one.
  • Given that the favorite characters of most Stargate Atlantis fans are McKay, Sheppard and their kind but harried medical support Dr. Beckett, that the favorite fanfic genre (by far) is Sheppard / McKay slash usually involving Aliens Made Them Do It, and that the show's canon features entirely unpredictable Ancient technology that is triggered into activity by especially Sheppard's genetic make-up and that they spend a lot of time actively searching for and experimenting with, the M-Preg practically writes itself. Usually it's McKay who ends up getting knocked up, apparently mainly because he's a neurotic hypochondriac who hates kids. Fanfic writers are cruel.
  • How the Light Gets In: Discussed, in a Seinfeldian Conversation kind of way, in one flashback. Laurel hates being pregnant, and tells Dean they're only going to have multiple kids if he became a seahorse.
    Dean: What?
    Laurel: Male seahorses carry the eggs.
    Dean: Oh. (Beat) I'm sorry, are you saying you'd fuck a seahorse?
    Laurel: Dean.
    Dean: Kinda sounds like you're saying you would fuck a seahorse.
    Laurel: Obviously in this scenario we're both seahorses.

  • DragonForce:
    • There's a story where Sam Totman gets "womb implant" surgery while drunk in Paris. And it will never stop being funny. Ever.
    • Another one (by the same author) where a hermaphroditic Fred Leclercq conceives sextuplets after being raped by one of his bandmates from Maladaptive. It's significantly less funny.
  • There's a Beatles mpreg fic in which Paul gets pregnant.
  • As if twincest wasn't squick enough, many Tokio Hotel fanfics involve Tom impregnating Bill somehow.
  • At least one person has done fanart and fanfic for The Who that involves Pete Townshend knocking up Roger Daltrey.

  • Homestuck: Trolls in general are common targets of this, thanks partially to their having frequently-vague Bizarre Alien Biology in canon, even though said canon does specify that trolls of all genders don't exactly do the whole pregnancy thing. There are also some fics that depict them as laying eggs instead, which is sometimes played similarly to pregnancy, still includes male characters, and still is clearly not a normal thing in canon (since that's specifically the Mother Grub's job). Assorted stories have depicted such things as being anything from a rare mutation to a vestigial trait that certain trolls still have, when they don't just decide to leave it unexplained. Eridan is the most popular target of mpreg, the trend originating from the fact that his lusus is a seahorse. A common trope is the idea that his Skunk Stripe is a natural trait signifying that he can be impregnated.
    • Referenced in Promstuck where Terezi suggestively says that she's going to get Dave "so pregnant" (it doesn't work). Played for Laughs, and is a sign of Terezi's lack of understanding of human biology.
    • "The Baby Is You" is this trope in music form, and aggressively bizarre to boot. Dave is not only pregnant, but specifically pregnant with his friend John, who is also standing next to and conversing with him. John offers to be the midwife but is told that he can't deliver the baby, because he is the baby. It's a Troll Fic which was created in mock protest of a forum rule forbidding certain characters (including Dave) from being depicted as pregnant.
    John: "How is that possible?!"
    Dave: "I don't know. Such is the magic of Skaia."
  • One of the plot devices in the Crack Pairing thread in the Order of the Stick forums. It doesn't get used very often, though, but when it does, it is hilarious.
  • Even Sweet Bro and Hella Jeff is not immune. Definitely Played for Laughs and Fan Disservice.

    Fanfiction based on Western Animation 
  • There's male pregnancy as horror fanfic. There is a Teen Titans animated series fic where Robin was used (quite unwillingly) for a Mad Science experiment...and impregnated with several hundred sea monster embryos. Monsters in the Closet - it can be found here in all its debatably wonderful, horrific glory.
  • The Mind of a Hero. The circumstances behind it, while Weird Science, are far from happy. It involves an odd device to bring Danny's inner shadow forth... and his first words: "Why my mother?!"
  • Transformers Mpreg is fairly common, starting with the fact that you can count the number of females in G1 on one hand but the number of males ranks in the thousands, and ending with them being robots. The tougher question should be how they can get pregnant.
    • In The Tyrant's Heir, this trope leads to the end of the Autobot-Decepticon war when Starscream becomes pregnant with Megatron's sparkling, and Megatron decides that he doesn't want to raise his child during a war.
    • Fifth makes Megatron the pregnant one.
    • Double-subverted in Couvade - Starscream's so-called 'pregnancy' turns out to be merely a phantom pregnancy, but he ends up getting pregnant for real.
  • Some Avatar: The Last Airbender slash writers have the disturbing tendency to get Zuko knocked up, usually with Jet's spawn.
  • Common in Invader Zim fanfic: even though the show depicts Irkens as "born" from machines, the idea that Zim and Dib could conceive a child is very popular (Smeets being one such example). (The "mom" varies.) In Short Supply is (or was) a popular story that Justified this trope more for the unusual pairing of Zim and Purple.
  • The My Little Pony: Friendship Is Magic fanfic A Royal Pain goes into depth about how male seaponies, and any male pony who has sex with a female seapony, will end up pregnant, even going out of its way to explain how this works using the magic of the setting. The sequel Heritage even points out that, because of this, seapony mares acts like stallions when it comes to dating and one night stands, being akin to pick-up artists.
  • In the My Little Pony: Friendship Is Magic fanfic Black Queen, Red King, this applies to any changeling that identifies as male, since changelings are biologically capable of holding both reproductive roles.
  • The popular My Little Pony: Friendship Is Magic fan-child Pandora is the child of Discord and Twilight. Discord layed her egg.
    Miscellaneous Fanfiction 
  • Fanfiction which is based on an Alpha/Beta/Omega hierarchy in general (such as a lot of Werewolf AU fic) will often have omega males being capable of being impregnated and giving birth (and in most settings alpha females being capable of impregnating others, though those scenarios are rarely explored outside lesbian-focused works).
  • Christian Humber Reloaded, a fanfic that includes references to anime, video games and other media, has the Original Character Season-Bringer, a dragon that's several miles long. Season-Bringer somehow gets pregnant with thousands of eggs, with no indication as to how this happened, and Vash is forced to get him medical attention before the eggs put too much pressure on his internal organs.


How well does it match the trope?
