Had an idea to transform a slender, but overly-curious Ryoko Hakubi into a lumbering rhino beast monster.

Still a WIP, but I wrote a pile of universe building fluff;

"Get Gurmed, dummy"

Rumors still persist about the disappearance of space pirate Ryoko Hakubi. Some say greed got the better of her (and good riddance), whilst others theorize she somehow forged a new identity to escape her debts.

As it turns out, both are kind of right!

Those thinking they’d find the skinny and fluffy-haired space pirate somewhere in the fringe worlds would never recognise her as the huge lumbering rhinocerous-like Gurm bureaucrat waddling toward them out of the fungal forests of Lumboi. Ryoko is now happily absorbed as Gurm Collector Ryu’kooga, having foolishly sat herself on a Gurm Throne designed to “reward” lower Gurmoids by promoting them into battle-hardened Rhinoforms. Ryoko, overcome with sensation rising through her on throne, let herself become gleefully led astray and her body transformed completely by the enticing charms and chemical ecstasies of the curious Gurm slime mould; who was not accustomed to human females in his midst, and intoxicated her far beyond what was typical for a transforming Gurmoid. Ryoko, soon to become Ryu’kooga, emerged from the throne room several weeks later a heaving and horny mass of transforming Gurmoid, playing with her ballooning body and feeling around her budding rhino-muzzle and utterly enthralled by her mental and physical ruination. With no regrets she was spotted wandering into deep into Gurm territory to find some ‘appropriate clothing’. Ryoko returned jittering with excitement to the throne room shortly after, wearing baggier clothing she knew she’d be bursting out of imminently. Ryoko soon became Ryu’kooga, edging over the threshold into true Gurmhood during an intense frenzy of body exploration and increasingly depraved sexual fantasy. The new 350 lbs Ryu’kooga, compelled to please her new slime master, left the throne room and joined the soldier-sect, the “Guukur’ank” with immediate command over a band of incompetent sloogs. It wasn’t long before her greedy nature and newly discovered hypersensitive sense of smell turned her into a natural Collector — the Gurm sheriffs who prowl occupied farmlands to intimidate villagers and steal food or “tithes”.

Ryu’kooga is described by the the occupied villagers of Lumboi as a morbidly obese doorframe-wrecking bully with a strange obsession with embarrassingly large comfort underwear. Ryu’kooga has been known to lessen the tithes if villages produce such huge cotton undergarments for her, lessening chafing and cushioning the movement of her enormous and growing frame.


You know you shouldn’t sit on a Gurm Throne human girl, they do strange things to Gurmoids. Gurm is all around us and these devices channel his dark energies... if a collector sees you in one you’re in trouble!!

You sloogs are seriously both spineless *and* superstitious. Those tubby Gurm collectors wouldn’t even know what they were looking at. That witch doctor donated it no strings attached, and I’m selling it to the monastery as an overpriced relic. Now get lost, I want to see if this thing is even capable of taking even my weight.


Greetings pirate Ryoko, I, the Glorious Defiler and Supreme Fungus, Gurm, ancient ruler of all seeded worlds, welcome you with a warm, loving embrace.

I represent the primordial slime that binds us in my eternal truth. I am impressed to find a lost human girl embarking on a path to eternal ecstasy in the service of slime.

“G...gurm? You’re real?! Holy fuck, I can explain, I didn’t mean to play on your throne! I just couldn’t help myself! It just feeels, mmmnnf, so nice and... different?!”

I am pleased with how… receptive you are to its delights...

“I… just really like the feeling! C…can I come back and... play some more?!”

“Yessss, I would love you to continue your journey…”

My newest acolyte, Ryu’kooga, you show great desire to grow, swell and bathe in the glow of your Lord Defiler. Feed on the succulent bounties of every world you visit to honor both my grandeur and your budding corpulence. As a new servant to slime you will experience perpetual joy and bliss during your transformative surrender to my love and teachings.

“I… I’m cumming again! Oh fuucck!!”
“Gurrrnfff Grrooowiinnnnggg! ”
“Me luv wearin ugli soft BIG BOY pants!”
“Mmmnnfff me want fatty fooopa even biggr! Me naughty Gurm!”

5. Gurm worlds exhibit superstitious and backward culture, guided by a supreme, highly intelligent hive mind [DEBATABLE]
6. Interplanetary conveyance/communication methods [UNKNOWN].
7. War modes:
1. Siege

Gurmoids organise into a highly collectivised but outwardly medieval society subdivided into semi-autonomous colonies on multiple planets. Gurm society is heavily militarised, with production focussed on the manufacture of small arms, siege engines, artillery and infantry armor.

Ideologically, Gurm-kind believe their destiny is to attain pure symbiosis with a host planet through domination of its biosphere. Gurm armies will seize new territory before rapidly turning over any food generation source to serve the collective ‘appetite’, furthering their growth and spread. Each conquest of food or nutrients is partitioned to offer tribute to the Supreme Fungus, which follows closely behind any invasion.

Once established, the Gurm Fungus will release mood-altering chemicals that can control the hoards of receptive Gurmoids in an area. Most often, these chemicals will result in collective hallucination, extreme feelings of love, happinesses, and arousal, promoting an implacable affinity with the Gurm.

Gurm territory is teeming with fungal life, some of which is extremely toxic to humans. The atmosphere at the surface is perpetually damp with an odour of decaying plant matter. Nevertheless, the Gurm fungus is capable of reinvigorating soils and promoting further life, “healing” overexploited farmland or desertified regions.

For reasons we can only speculate, Gurm appear immune to ageing, are capable of extreme body mass changes and can regenerate exceedingly fast after injury. Intelligence on the matter is limited but suggests that Gurm spores are capable of specific gene activation and cell repair.

Social status in Gurm life is gauged mostly by body mass, which, for a Gurm-follower, signifies devotion and the quantity of energy consumed in the name of the “god fungus”. The highest Gurm honor (and personal ambition of all Gurmoids) is to finally grow too large to move, becoming immobile akin to a true fungus — at this point you are willingly consumed into the greater Gurm Fungus and finally achieve eternal and exquisite “living death” as an enormous fungal hybrid. Consumed Gurmoids often retain a good semblance of their former selves, and report a feeling of bliss and nirvana, espousing the “Gurm Afterlife” to a cadre of listening cultists — the basis of Gurm mythology. Gurm “monasteries” are often built around the most vocal of these bloated “prophets”.

The most common Gurmoids are Tusked Sloogs; an underclass of servile helpers who perform a number of assistant roles to larger beasts or superiors within the Gurm hierarchy.

Two middle castes of Gurmoid based on roles within the colony.
1) Worker/Farmer — “Guukur’aey”
Mostly tasked with cultivating slime pools or the Mooga bean; the main staple and ingredient of the gruel most Gurmoids seem very fond of.
2) Soldiers/Grunts — “Guukur’ank”
The standard foot soldiers of Gurm, who come in a variety of shapes, sizes and disciplines.

Specialised castes
1) Clergy — “Oomk’jur”
The religious and spiritual sects that often form around a given prophet fungi, chronicling history and writing new scripture to add to the turgid and extensive Gurm canon.
2) Collectors/Sheriffs — “Mulkur’t”
Administrators of Gurm colonies. The most feared and respected of Gurmoids, they command the law and collect tithes from occupied regions. Often promoted from within the ranks of Guukur’ank.
3) Metallurgers — “Klankur’t”
Gurmoids that have mastered smelting and smithing. Klankur’t are mostly artisans that work independently in their own workshops, they are impelled to work constantly to arm the hordes of Guukur’ank and provide tools to the local Guukur’aey.


#Absorption and Phenotypes

When originally non-Gurm lifeforms, sometimes willingly, devote themselves to spread of the Gurm fungus, physical attributes alter significantly according to a set of dominant phenotypes. Absorption usually begins after prolonged exposure to Gurmoid ecosystem or high concentrations of slime mould spores. Human absorptions are not unheard of, but very rare owing to a general repulsion at Gurm life that precludes long exposure to spores. Witnesses in fringe regions report that Gurm-absorpees become grossly and deliberately overweight, develop fetishes or unusual obsessions, lose interest in social matters and are solely driven by an insatiable, almost masturbatory, need to consume. Until a Gurm infestation/infection is cleared from a planet, human commanders should be incredibly wary of these warning signs among their civilian population.

In general, Gurmoids appear to lack any sexual dimorphism, with many speculating that they are in fact asexual and reproduce as such. No mating or courting rituals have ever been observed, rather, a Gurmoid appears most enamoured by individual fetishes and their own physical attributes and resemblance to the typified and ‘ideal’ amorphous fungal form; the latter explaining why extreme weight gain, limb atrophy and gradual engulfment of former shape are deemed a desirable outcome for Gurmoids.

# Slugforms
The most common form of a Gurmoid is a mollusc-like slug, with or without arm appendages. The majority of slug forms are the native, and numerous types of Sloog inhabit Gurm territory. Absorpees and members of any caste can develop slugform characteristics at any time.

# Rhinoforms
A heavy set build with tough hide impervious to sharp projectiles, dense skeletal build, low center of gravity and often adorned with large horns. Superficially similar to Earth Rhinoceros in cranial structure, Rhinoform appearance shows gradually in Collector/Soldier castes as they progress or receive promotion, presumably driven by unseen Gurm spore-mediated mutation. Cranial shape appears to limit speech function but increases impulsivity; we assume this may create problems managing temper, as well as sexual and eating urges.

# Fungoforms
A late stage Gurmoid phenotype where mobility and limb appendages are lost to an amorphous chitinous fungal mass — a hybridization with the greater Gurm fungus. Associated with fungal prophets stage development, fungoforms may be connected together to produce a sort of hive mind.
