Slime Girl

Go To
Without beating around the bush, a slime girl is a girl made of slime.

Slime girls are a thicker variation on the idea of being made of water. They tend to come in a variety of colours and substances, which range from fairly harmless unspecified slime to piles of living waste.

Slime girls usually follow a similar pattern. Their lower halves will usually be spread in puddles in which they could be mistaken to be bathing. If they do have legs, expect their feet to create "splashes" of slime with each footstep or at least deform on contact with the ground. When they eat they simply ingest the desired object, without leaving any waste substance. The "hair", if there is such a thing, will generally be a darker shade than the rest of the body and will appear to flow down the slime girl's back like a cascading waterfall.

Whilst slime girls don't mind small droplets of water, if deposited in a sufficiently large body of water they're likely to dissipate and die.

This trope could be considered Blob Monster meets Cute Monster Girl, and like a regular Blob Monster, Gelatinous Encasement is a common attack method.

Their personality varies as with most races, although they tend to be rather laid back and gentle unless provoked. In fictional nature, slime girls are usually the bottom rung of the ladder. Those made of liquid metal, on the other hand...

    Anime & Manga 
  • Princess Vina from Dragon Half is a slime-half.
  • In Fresh Pretty Cure!, one of the villains creates a shadowy facsimile of Setsuna who morphs her body into tentacles as well as melts into the shadows of her opponents to ambush them.
  • Sloth from Fullmetal Alchemist (2003) can turn her body into slime, but unlike most examples she's not a Cute Monster Girl as she never mixes her slime form with her human form.
  • A spoof of the T-1000 appears as the main antagonist of a special two-part episode of Kochi Kame. She can not only mimic forms but also turn into weapons, though whatever non-character object she turns into retains the shades of her true and civilian forms.
  • Monster Musume:
    • Suunote  is a blue and green slime girl who can assume humanoid form, is able to mimic anyone she knows, and has an antenna that lets her share others' feelings. She is an illegal immigrant into Japan and appears to be mostly harmless, though at times, she can forget her own strength and smother her friends to the point of suffocation if not careful. As slimes are so rare and unknown to even the monster community, cultural exchange coordinator Ms. Smith refuses to name her a "monster" to avoid all the paperwork dealing with a new species an illegal immigrant would bring, given that she never receives a pay raise.
    • According to the anime's bonus materials, there are also various slime girl subspecies, including the acid-based red slimes, the poison-based green slimes, the nectar-feeding pink slimes, and the black slimes, transformed by human pollution.
  • The Slime Sisters that work under Wilhelm in Negima! Magister Negi Magi, who are extremely resilient to physical attacks, capable of shape-shifting, and possess some control over water.
  • Queen's Blade has the immensely popular Melona (so popular in fact that the second season's first ED is sung completely from her perspective with the lyrics and visuals emphasizing how erotic she is). She has all of the hallmarks and perks of an amorphous creature with every part of her body being her weapon, including and especially her breasts. Her base form is a pink gooey mass that she can mold into anybody she chooses, regardless of gender or body mass; she can even copy weapons and fighting styles, the only telltale sign between her and the real thing being the shape of her pupils (and a pink outline drawn around her, but it's implied that only the audience can see it). While not shown in the anime, she's very capable of absorption and can use the mass to either restore herself or make herself even stronger. Under the right circumstances, she is very much immortal. In short, the best way to describe her is as a pink T-1000 with weaponized acidic breast milk.
    • Despite her appearance, she's more than capable of taking on even the strongest of the fighters and has shown to be implacable incarnate and a Magnificent Bastard. Not only does she have good manipulative skills, she's not afraid to fight against anyone as she goes up against Leina several times, almost winning each time and surviving techniques and ploys that would have killed anyone else, fights the champion Aldra twice in a row and survives both times, and holds her own against Menace, a necromancer. In Rebellion, she fights under the influence of a set of armor pieces that, although supposed to make her stronger, also disorient her focus and form with the constant perverted vibrations, subdues most of the main cast with a simple water spell, and survives a direct hit from Claudette. Damn.
    • Even moreso, while not seen in the anime, Melona in Rebellion is turned up a few notches after absorbing an ancient demon, sporting a spiffy new outfit to go with it.
  • Sailor Moon:
    • In the Monster of the Week category is Jamanen, known as Jellax in the dub. She has quite a fanbase as it is and even makes it as a recurring enemy in one of the SNES games.
    • Interestingly, slimes are a slightly recurring type of monster; the later episodes feature a bunny slime-girl named Peropero who manipulated malevolent hard candy. In one of the closing episodes, an army of female humanoid slimes are born from the many unused demon seeds.

By source material: By work:
  • Several show up in FREAKIN GENSOKYO as common monsters.
  • The Jellax Saga reveals that Jamanen is the last of a race of slime beings known as the Jellax.
  • Vow of Nudity: One story takes place on an island infested with oozes, and their matriarch has evolved into a massive slime girl who serves as the story's final boss.

    Films — Live-Action 
  • Parasite Eve features this in a particularly surreal scene of the Mitochondria Eve taking form while she dances and promptly has sex with the bystander witnessing it.
  • Terminator 2: Judgment Day gives us the Spear Counterpartnote  to this in the T-1000. Although he spends nearly all his time solid, he's fully capable of melting to hide on the floor, slip through bars, or liquify his head around a punch and reshape it into his arms as a counter.

  • Agape in the Apprentice Adept series is a giant ameoba who normally uses her Voluntary Shapeshifting abilities to appear as a human woman but has to revert in order to absorb nutrients.
  • A variation in The Great God Pan when Helen Vaughan turns into a shapeshifting primordial ooze after dying.
  • Monster Girl Doctor has Lime, the green slime girl nurse working at the central hospital and Molly, the purple shoggoth serving as the manager of the Deadlich Graveyard City district. The anime also adds an unnamed slime girl patient of Dr Glenn that has a servant cart her around in a bathtub.
  • Overlord (2012): Solution Epsilon, the "Shoggoth Assassin" of the Pleiades Battle Maids, is slime-girl played for Fanservice. Taking the form of a beautiful meido, she's actually a sadistic man-eating shapeshifting Blob Monster who eats people for the sheer pleasure of their agony as she digests them — the sheer delight she takes in her kills, and the horrific way she eats, makes her even scarier than her fellow man-eaters, since they do it out of hunger and having no reasoning to exempt humans from the menu in contrast to her doing it purely For the Evulz.
  • Rimuru Tempest, the main character of That Time I Got Reincarnated as a Slime, plays with this trope gender-wise. First off, he has a male identity due to his past life. Despite that, his human form is heavily based on the first human he ate, a female friend of his who offered her dying body to him, resulting in him having an appearance that primarily looks like a girl. However, while he may look like a girl at first glance, when it comes to his physical body outside of his face, he's completely sexless, no breasts or genitals whatsoever, just like his regular Blob Monster form. So at first glance he's a straight example, but when you get to know him, he's a Gender-Zig-Zagging example.

    Tabletop Games 
  • Surprisingly, Dungeons & Dragons does have a canonical slime girl monster or two:
    • The Yochlol is a demon in the service of Lolth, Demon Queen of Spiders, whose natural form is a yellow slime with tentacles and a single massive woman's eye, but it can also freely transform into an attractive drow woman.
    • The Ghaunadan is a sapient green-colored slime that can freely transform into the form of a humanoid, typically favoring whatever will pass most easily in the society they are infiltrating — which usually would be a drow woman. They are servants of the evil god Ghaunadaur, so they are Always Chaotic Evil.
    • Dungeons & Dragons 5th Edition has the Plasmoid race, a heavily modified reinterpretation of a monster from Spelljammer. These are non-malicious sapient slimes who travel the universe in magical flying ships, and a fully playable race.
  • Parodied by Pathfinder with the "Apostheotic Mimic". Mimics, if they survive an encounter with an adventurer, become Intrigued by Humanity and may eventually attempt to become one-and inevitably fail horribly at it. They go irrevocably insane, desperately trying to forget how to take on humanoid form but are never able to become mere mimics again.

    Video Games 
  • Anvil of Dawn features mud-like goo girls as sturdy enemies near the end of the game.
  • Crush Crush adds Cute Monster Girl variants of some of the main girls in its DLC, including Jelle, who resembles Elle except made completely of slime.
  • Dot Kareshi has a slime boy as a love interest... though it's easy to mistake him for a slime girl.
  • Kingdom of Loathing has the Special Challenge Path "Gelatious Noob", based on Pathfinder's Apostheotic Mimic mentioned above, a Blob Monster who is Intrigued by Humanity and does their level best to become a person. Luckily, this is a Lighter and Softer take on it, and they're eventually rewarded by becoming a real human being if they can rescue the King. They can't eat, drink, or read books, or properly equip armor and weapons (they gain the attack range but none of the special effects), but instead can absorb a number of certain items permanently (such as the Robartender's disgusting cocktails) for new abilities — including the ability to eat and drink, in a very literal version of You Have Researched Breathing.
  • Lobotomy Corporation features Melting Love, a pink and seemingly innocuous slime girl, as one of its numerous Abnormalities. Her threat level is ALEPH (generally reserved for extremely dangerous Eldritch Abominations) and she may "bless" employees with a slime heart which can spread to others and transform them into Blob Monster minions. Should she escape containment, she transforms into a massive, hunchbacked Blob Monster herself, hellbent on killing everyone in the facility unless Suppressed.
  • In Magical Starsign, one part of the quest causes you to open a door in the robot's Gummi factory. The resulting Gummi Girl is an Optional Boss that carries a lot of Fridge Horror.
  • Nursery Slime features a very cute sky-blue-colored slime girl that originally appears as a normal slime being that the Protagonist names "Qu", but eventually retains herself as her slime girl-self over the course of the game who develops along with the story. The MC Oz has the potential to develop equal feelings for Qu and even marry her as one of the endings that concludes beautifully.
  • Mutantheart from OMORI is an imperfect clone of Sweetheart who appears to be made out of slime. Her creator is one-third of a trio of sea witches called the Slime Girls, but ironically, they are not actually made out of slime.
  • Pokémon Sword and Shield has Alcremie, which is a cream-based variant that turns into a giant cake for her Gigantamax form.
  • Princess Maker 2 has one enemy encounter be a reddish slime creature vaguely shaped like a long-haired woman. It tends to be one of the less hostile monsters.
  • In the final chapter of Resident Evil 6, Carla Radames becomes a rather nasty combination of this and Grey Goo who decides to just eat the entire ship you are trying to escape through to kill you, along with creating multiple clones of herself to attack you as well.
  • Shantae: Half-Genie Hero:
    • Slimegals resemble pink blobs when moving around but can take the appearance of cute girls made of pink slime when they spot Shantae. The animation of their sole attack actually shows that the "tongue" snatching Shantae is the Slimegal giving her a heartfelt hug resulting in Gelatinous Encasement.
    • The Wetgal enemies also invoke this but are blue, less cutesy (despite how they curtsy), and more aggressive. This comes from being a Cute Monster Girl counterpart to Wetmen, who prefer more of a bipedal fish monster cyclops form for fighting.
  • Double from Skullgirls, a rare slime girl variant, is a mimicking dark blob disguised as a nun.
  • Slime Date Maker, a downloadable title by Jamie Barker, plays with this by letting you make Slime People of any gender, not just girls.
  • In Space Station 13, there is a high probability that any member on the science team working in the Xenobiology lab will become one of these after spending enough time breeding green or black slimes. Greens will turn the character into this, blacks will turn the character into a normal slime that you'd find in the lab.
  • The Inklings and Octolings from Splatoon are a somewhat odd variation, being cute humanoid squids/octopi made of ink. The Sanitized Octolings from Splatoon 2: Octo Expansion, on the other hand, are a creepier example, having been more or less fused with the liquefied remains of test subjects from the Deepsea Metro who managed to assemble the very blender used to kill them, convinced it would take them to the "Promised Land".
  • String Tyrant has a distinctly horror-based version called Claygirls. They are definitely female but lack any attempt at human features, instead having a featureless blank space for a face. The fact that they spend most of their time disguised as objects around the manor also sets them apart.
  • Witch Hunter Izana: Slimes are a late game enemy type. They can turn your party members into Slime girls. They are very, very stupid. Also the hidden gem vendor Vivia is a slime girl witch.

    Web Animation 

  • Talps from Cassiopeia Quinn is pretty much this, when she wants to be (for her Kettering).
  • Teal from Delve. Her family members are more traditional horrific slimes; Teal just prefers human form.
  • Averted in El Goonish Shive: Instead of becoming this, the Omega Goo merely becomes stunned by Ellen's Female Variant #5 beam. The title of the relevant strip refers to this though.
  • Marcus Snoburgher from A Modest Destiny is a male version. He was a regular Slime before he took a shine to Maxim and mimicked his shape. Being a living bogey, he's actually got a Line-of-Sight Name: he introduced himself as Mucus SnotBooger and the guard mentally translated.
  • The King Slime (actually the slime Queen gender-wise) in Nast the Enchanter.
  • The premise of the webcomic Slime Star. Regular "slimes" are the R-selecting larvae of slime people. The protagonist is a slime who lived long enough to achieve sapience after being befriended by an adventurer.
  • Synthea from the webcomic of the same name was put into a stasis pod and woken up with experimental biotechnology by a good Mad Scientist far in the future. The result was a green jelly-like body with a confused amnesiac human mind. She can change shape at will, stretching body parts, creating mallets, etc., although this is not perfect, as her body drips and oozes constantly — her "at rest" state is a puddle, and she is stuck sleeping in a big barrel. She's also more or less immortal — she has survived being cut into pieces and having an exploding weapon go off inside her head with nothing more than a headache.
  • Tales Of Gnosis College has a bonus sequence called Goo Girl Genesis which is Exactly What It Says on the Tin. A female undergraduate is turned into one of these as a mad science experiment.
  • Ditto for Myrrh from The Wotch, a maid who tried to clean up a pile of magical ingredients (with a pinch of ginger) that her insane Wizard master left out. The mess fought back, and the resultant mass vaguely took on the maid's shape, memories, and personality (with a slightly better body). She maintains the shape of a nude woman, though she often shapeshifts her body to give the appearance of clothes as a sight gag. Originally a bit of fanart from a sub-comic who was made a bit character in the main comic, and later becomes a secondary character, a roommate for Unlucky Everydude Ming.

    Web Videos 
  • An infamous moment in Vinesauce history occurred during Vinny's final stream of 2019, in which he played AI Dungeon 2 and tried to create a slime girl by using the maclankey on a slime that wished for life. The result was "a beautiful woman wearing nothing but white lingerie". Whether she was actually still made of slime at that point is open to interpretation, as he shut down the session when it took a turn for the pornographic immediately afterward.

    Western Animation 
  • Adventure Time has Slime Princess, who looks like a small blob with nubby arms and a face. In one episode, we see the whole Slime Kingdom, including her nearly identical (but apparently hot) sister, Blargatha.
  • Inque from Batman Beyond. She has nearly killed Terry and Bruce and still serves as a real threat no matter what episode she shows up in. She can shapeshift, as well as being super strong and has telescopic vision.
  • The Batman: The Animated Series episode "Growing Pains" has one in the form of Annie, a girl with Laser-Guided Amnesia who spends much of the episode clinging to Robin and crying on him because thus far he is the only person she can trust to save her from the mysterious man who has been following her and begging her to come home. Robin reciprocates her apparent feelings, and we even get an Imagine Spot of them together that makes him blush. The man pursuing Annie turns out to be Clayface, who survived his last fight with Batman and had been laying low to recuperate ever since. Using what power he had, he made a clay person that was intended to take a quick look around the area for Batman and tell him if the coast was clear. Strangely, the revelation that his new love interest is not only made of slime but essentially Clayface doesn't deter Robin's feelings any. He even demands that the hardened criminal bring her back after finding out.
  • Ben 10: The Lenopans/Sludgepuppies are mud-like aliens who naturally look like amorphous blobs but can shapeshift into humans. They are also shown to be able to take on a more humanoid sludge form. As it just so happens, we've only seen females take on the latter form.
  • The Darkwing Duck episode "Slime Okay, You're Okay" has Gosalyn get transformed into a slime creature after being exposed to a concoction created by Bushroot.
  • Madame Rouge of Teen Titans (2003) is possibly one of the scariest examples of this, being a "slime" girl by virtue of having total control over her body structure with enhanced speed, strength, endurance, and the ability to not only change her appearance and voice but also to shape her limbs into weapons à la the T-1000 to boot.
