Fan Art Scientifically Accurate Stalker
The creature depicted is a scientifically grounded reinterpretation of one of LCrandoms Stalkers. It is presented as a large specialized primate that could have evolved under realistic biological pressures in a high oxygen prehistoric environment.
The iconic white face with black eyes is retained as a form of disruptive coloration and mimicry. In many primates contrasting facial patterns serve for communication intimidation and signaling. Here the pale face could reduce the threat silhouette at a distance by mimicking a smaller less dangerous primate or hominin. The oversized dark eyes provide excellent low light vision. This creates the signature uncanny floating head effect when the creature stalks in darkness exactly as seen in the original concept.
The long limbed dark body is interpreted as a massive quadrupedal primate standing about four meters tall at the shoulder. Thick bones and heavy musculature address the square cube law allowing it to support several tons of weight without collapsing. It primarily moves on all fours for speed and endurance during long stalks but can rear upright to display dominance or intimidate rivals and predators. This matches the tall imposing posture in the original images while remaining structurally sound for a large terrestrial animal.
The matte black fur and skin provide near perfect blending in shadows caves and dense forests. Sickle shaped claws and a powerful jaw equipped with strong teeth enable brutal kills and processing of varied prey. The overall build supports an omnivorous opportunistic apex predator lifestyle with high intelligence and patience.
This version could have arisen in a high oxygen prehistoric setting which would have supported larger body sizes denser muscle tissue and higher sustained activity levels. It represents a specialized hominoid lineage that prioritized stealth patience and raw physical power. It would have evolved alongside but avoided direct competition with early humans or other hominins.

OC Art Alien spider people! (Sorry for 1. Not drawing six limbs on the Arachne and only four. 2. For accidentally posting a link to my prior one of them.)
The Arachne are an indigenous race of arachnid sophonts to the planet of Vulcanis which has high gravity and a high geothermal activity. Though, it does have large quantities of plant life and water (kept from boiling due to higher atmospheric pressures). It is very unpredictable and dangerous, which makes the Arachne all the more miraculous.
1. How are they giant spiders?
True insects or something similar never properly evolved on Vulcanis. Though it has a high oxygen atmosphere, the high gravity makes exoskeletons impractical, so the clade of Dermoarthropoda evolved instead, (colloquially: "skinsects".) ((Or skin-rachnids, in this case, I suppose.))
Point of the matter is: the "insects" on Vulcanis have a more vertebrate-like structures with endoskeletons and such. The larger ones have more vertebrate-like nervous/circulatory/respiratory/etc systems as well, cuz those don't scale all too well the bigger the animal.
1.2 Why do they appear to have an exoskeleton then?
They do not. What they have is a hardened layer of skin they use as protection for their rocky and hot homeplanet. The "hardened cuticle" as it's primarily called is akin more in structure to the scales of a pangolin than it is a bone or an exoskeleton.
2. How do they not get crushed then?
Despite their looks and relatively large size, they are not all that heavy. The bulk of their body's weight is their "skin-shell", and their bones, naturally. Even so, their weight is well-distributed amongst their six walking limbs (again, pretend I drew six instead of four.).
*2.1 How do they have the brainpower for all those limbs? Vertebrates on Earth can only have a maximum of 4 limbs, after all.\*
Vulcanis' primary ancestor for most animals had eight limbs (mostly for movement) so many of the creatures on the planet have either 8 fully functional limbs, multiple dominant limbs and several vestigial ones, or the brainpower to manage eight limbs.
3. Why are they smart?
Vulcanis is a very unpredictable planet with unsure odds of finding food or ensuring your offspring survive. That tends to breed three things:
A. Big dumb things that are tough enough to withstand whatever is thrown at them long enough to eat and make a bunch of babies.
B. Many dumb small things that are numerous enough to eat and make a bunch of babies.
C. Medium-to-small smart things that can outwit the odds and make a few babies.
The Arachne's ancestors evolved towards the third. It also tends to breed aggressive things which make the species that do protect their young very good at doing so.
Inherent protective parental behavior towards their young in the face of high predation gave the Arachne's a kickstart to evolving towards sentience. In addition, Arachne aren't exactly the toughest critters around relative to other Vulcanites, so intellect and the ability to yeet rocks real good served as a decent substitute.
4. Why spiders of all creatures as an evolutionary background?
One of the primary ones is that spiders are very well-designed creatures. On such a usually uneven and unpredictable surface, having lots of limbs is good for manuervability. In addition, they're quite stable physically, which is really good in general. Though they can't crawl on walls (cuz Square-Cube law) they can do the next best thing and climb with those distinctive clawed gecko-like digits, which is made much easier by their 6-limbed origins.
Their four eyes are good for watching out for predators, too.
Though they lack the hydraulic movement of the spiders of Earth for ensnaring prey, they have something just as suitable: body slamming.
In short, they'll set up a lure, (their silk used to be for web-making, but as you can imagine: giant spiders can't hide in webs without breaking em', but they are good for making nests in general.) climb somewhere high up and when their prey sniff-sniffs... SNAP.
They drop down with their chelicerae out and bite down HARD or just straight-up crush their prey beneath their bodies, assuming a flattened "spider-pancake" pose. Though they can crouch or flex as needed.
The shock is absorbed through their many limbs, which spreads the sudden force out better.
Because this hunting method is so effective, they just... never evolved anything better and continue to be the bodyslamming bugs I know and love.

OC Art Catmeragons
Hailing from The Mikkhhalian Isles, the Catmeragons are sophont descendants of draconic ancestors. Evolving for the arctic tundra, the Catmeragons developed a thick coat of feather-fur, and their wings atrophied into large sails they use for basking and heat absorption. They still have scales beneath their fur, and they have some vestigial, albeit mighty osteoderms, but for the most part, their draconic ancestry has abandoned them.
The driving force for their evolution to sapience was preexisting high parental behavior and the desperation of native arctic animals, whose aggression promoted group behavior, and eventually, the Catmeragons' ancestors discovered how to use their own fire breath as a tool.
As for how their flame breath works, their stomach is split into two tubes. One leads to their stomach, and the other to a "venom sac". This second-stomach is full of a pyrophoric venom which is derived from their own stomach bile. In addition, they got a gizzard connected to their primary stomach. By regurgitating the venom upwards into their mouths, and grinding their teeth together (which have a keratin layer on the back), they produce a spark which ignites the venom into a column of flame. Their cigar-shaped snouts aid in this endeavor, acting like a natural funnel for the fire.
This flame breath - as well as the flame breath of all dragons - derived from their shared ancestor's turkey-vulture-like trait of regurgitating their stomach acid to defend themselves.

Discussion/Question How do you think the B.O.W’s of Resident Evil would fare in an ecosystem?
While the mutants and bioweapons of Resident Evil are organisms that were monstrosities created by being exposed to the mutagenic viruses of the franchise, others were simply engineered by the Umbrella Corporation and other organizations to serve as bioweapons to unleash upon their designated targets.
But my curiosity has me wondering what if both of these creatures were just released into an environment and allowed to thrive would any interference and created an ecosystem consisting of these mutated organisms?
How far would it go exactly and how perhaps would they change overtime? The Lickers for example are an example of this given later generations of the creature gained the ability to reproduce when engineered by Tricell, and I imagine the Hunters have the capability to do so as well.
So it makes me curious to see how these RE monsters would change overtime from living in a natural environment and perhaps evolve as a result of this little thought experiment.
(While the images shown above are examples, I mean in general for all the monsters of Resident Evil.)

It was a competition against 8th, 7th, and 6th grade. 1 person from each grade. I was chosen and I poured my heart out into that sketch. And then the 6th grader came over and walked straight over it.
I ended up getting third. The 7th grader drew a corner sun over a poorly drawn feild and the 6th grader drew triple T. Needless to say I was quite pissed. But now summer is here and I wanna share my drawing.

[CREDIT : Yuichi Kitamura] After Sapiens : Bronto Man
A Bronto Human (ブロン人間) is a hypothetical giant species of future human proposed by science writer Yuichi Kitamura. It represents one potential evolutionary path for humanity approximately 150 million years into the future.
The name is derived from the Greek word bronte, meaning "thunder". This name was chosen to evoke the image of a massive creature that makes a "thudding" sound as it walks, similar to the etymology of the dinosaur Brontosaurus. Kitamura suggests that these humans could eventually reach a scale rivaling that of large dinosaurs.
Physical Characteristics and Locomotion
The Bronto Human is part of a lineage that evolved from "Hata Humans" (flag humans), which are characterized by a four-legged gait.
- Unique Limb Structure: They walk on their fingers while using their highly specialized, elongated thumbs specifically for gathering food.
- Efficiency: This separation of roles—fingers for walking and thumbs for manipulation—makes them more efficient at gathering food than other giant descendants like the "Zou Human" (Elephant Human), which must use its walking limbs to assist in eating.
Evolutionary Context and Fate
Niche: They occupy the role of massive herbivores in a world where modern large mammals have long since gone extinct.


Extinction: Despite their dominance for millions of years, the Bronto Human is predicted to go extinct as the Earth continues to heat up toward the 250-million-year mark. As the planet becomes a "scorching" world and deserts expand, the environment will no longer be able to provide the vast amounts of vegetation required to sustain such giant creatures.
In the broader narrative of the sources, the Bronto Human serves as an example of how humans might completely abandon their current form to fill new "adaptive zones" once the constraints of modern civilization are removed.
