There are obviously a lot more locked away in the GM section then you'll find here. But these are some commonly known-of ones to get you some rough idea of whats out there. Find more and expand your database! If they don't eat you that is.

The Canines

"Man's best friend got some new friends."
Of the mutated species, the canine is considered one of the more feared due to their pack hunting nature and high tendency to carry diseases. As the world fell many dogs were left without owners, unfortunately the cute fluffy ones that wouldn't be too bad died of starvation locked in their owner's home. Its the ones that broke out of their houses that we're concerned about. Their aggression levels vary, though some people have found mutated dogs that are still quite friendly towards humans. Whole new species of canine popped up thanks to the dogs who mutated without their owner dying and simply remained domesticated.

Class 1 Canine
Usually just under a meter in height when on all fours, the most common wild dogs come from the mutated domesticated dog. Its been years since the fall of mankind so the wild ones have become quite wild, though they have sometimes displayed friendly behaviors.

Class 1 includes non-mutated wolves, those things were always scary.

 

 

 

 

 

 

 

 

Class 2 Canine

Massive and monstrously mutated. The class 2 species of the canidae family tends to be the big problem. They are single handedly enough to take down a human with ease if they get close and still tend to use pack hunting. They are impeccable hunters with their keen senses but terrible at stealth compared to their class 1 cousins so you usually get some warning they're coming.

 

 

 

 

 

 

 

 

 

The Felines

"We endangered them, but when we became endangered they apparently held a grudge"
The solitary big cats became a really big problem when the world fell apart and became overgrown by flora. They started reproducing quicker and due to their territorial nature they started spreading out further and further in search of unoccupied territory. Every continent seemed to have some sort of big cat that could become a major problem. Evolution had already refined the cats into perfected predators, mutations barely had any work left to do. Depending which continent you're on which cat is going to eat you.

Cheetah
Everyone was so focused on the pack hunting lion mutants that they forgot about the cheetah. Now the size of a small horse and hitting top speeds of 90mph, the cheetah is africa's premiere mutated feline murderer. Their mutations also gave them a lot more endurance then a big cat should have, you might run out of gas before you can get away from one of these.

 

 

 

 

 

 

 

 

 

 

Tiger
We're not sure if its the bengal or siberian variant that got mutated and spread into the spiky one we're all afraid of today, but either way its huge. Adults weigh an average of 900 lbs and roam the asian continent. These tigers are basically powerhouse predators relying on sheer strength to overwhelm whatever they come up against. Actually considered the least dangerous of the big cats due to the simplicity of their attacks, still the scariest though.

 

 

 

 

 

 

Jaguar
Native to central america, they just started wandering around the americas after the apocalypse. Jaguars are problematic because their mutations are tied to the naraxas, and they were already nocturnal stealth hunters. While they aren't the biggest out there like the Class 2 mutants, they somehow gained access to naraxas powers which is a whole other kind of problem. They also became intelligent, a captive one was literally taught english. It couldn't speak, but it knew algebra.

 

 

 

 

 

 

 

The Naraxans

"If you spotted it first, leave it alone and it'll go about its business."
Wildlife from the world of naraxas generally tends to favor stealth and ambush tactics along with spiky armor piercing weapons. It took awhile to even prove that they weren't just mutated denizens of earth but naraxan citizens who got along with humans were quick to point out they recognized them. Though, most of the naraxan wildlife that snuck through are actually not predators. Our daylight cycle dissuades them from hanging out here, but the herbivores and scavengers looking for new safe grazing grounds were quite content to wander in. Naraxan wildlife is more important to recognize simply because knowing that its non-predatory can prevent people from attacking the scary looking ones and provoking attacks.

Skulker
They're actually named Nwexas Suflecto but humans just call them skulkers. While they look very humanoid they aren't intelligent and are simply predators. They tend to max out at about 5 feet in height but some will get bigger. Their ambush tactics can cause serious problems but they aren't individually threatening. They often roam in small packs, though large colonies aren't unheard of if there is enough food to support them. While they are mostly a slash and tear predator, they will go for stings with their tail if they can. Their venom isn't that effective on mammals from earth and will at most paralyze a limb.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Vorapede
Despite its terrifying size and appearance, the vorapede is a scavenger that can often be found crawling around in the day looking for a mix of carrion and fungi. These massive beasts rely on their size and armor plating, as well as the fact that most naraxan predators aren't out in the day, to avoid fights. They are quite docile and can be approached, just don't try to ride it. All known attacks happened upon threatening the creature or its nest, otherwise it just wants to continue about its day without any trouble.

 

 

 

 

 

 

 

 

 

 

Shadow Demon
The apex predator of the naraxan world is truly the sneakiest of them all. Some attempts to claim the title include camoflauge, outright invisibility, perfect nightvision, being absolutely silent, and of course just being big and having the most teeth. But the king of the naraxan ecosystem took a simple route, parasitism. This parasite can live in almost anything because it's small worm-like body grows into the body it inhabits. As it grows and infests the body it will eat away things it determines to be non-vital to make room for itself and then infiltrate the digestive system to steal food. It has no natural predators and reproduces almost asexually. It steals genes from whatever its host is and augments its offspring with those, said offspring come in the shape of its smaller wormlike body.

There are some wildly varying species due to the way it reproduces but only one is called "shadow demon", the intelligent one. It got its name because the parasite is actually symbiotic and even desirable to some which causes some people to willingly accept it. It's own immune system, stolen from its entire ancestral line of hosts, will protect its new host from disease. If the host is co-operative it will give them other unique benefits as well, such as shadowmancy and weird tentacle things that can be considered a weapon. As well as a friend to talk to, because the Shadow Demon species can talk by vibrating your ears with its body. Only you can hear it, and you have to speak out loud for it to hear you, but it is there - and it is listening. This ability is how it became the apex predator, it infested humanoids and convinced them to help spread it. There are entire Naraxas tribes that worship the shadow demons and willingly take them into their bodies as a coming-of-age ritual. One such shadow demon infected a human, and that is how we figured out the naraxan language.

Though there are downsides. The host will need food to sustain both themselves and the parasite. The parasite sometimes has its own agenda, usually in reproducing and spreading. Causing the infected to actively try to infect others, this is a big problem with the shadow-demon species because its intelligent hosts will be very clever about doing this for it. Also having a voice in your head is not good for your sanity, and there are some headaches and cramps involved for some general mild discomfort. Most obviously, your lifespan shortens dramatically since a lot of your organs will be eaten and the instant it gets hungrier then you can provide it starts eating you. Hosts that keep their parasite well fed may start to notice strange growths and mutations that turn them into walking horror monsters, but very physically capable predators in order to find the both of them more food.

Common methods of becoming infected include eating it, it getting into an open wound, a host deliberately implanting you with it, and a larger one shoving itself into you. Be sure to wear pants.

 

The Daezrans

"At the very least, they're honest."
Wildlife from the world of daezra have a very high regard for the brute force path of evolution. The daezra homeworld was being burned a lot and any species that were reliant on specific ecosystems soon went extinct as their empire spread and destroyed native ecosystems. The one's that lived were general purpose omnivores, and without a reliable ecosystem camoflauge wasn't an effective evolutionary tactic. The end result is that daezran wildlife found the most by being big and just overwhelming any situation it came into. Because of the lack of stable ecosystem, they're also more aggressive then most typical animals we're used to since they are used to encountering things they don't recognize and trying to eat it. Most of these creatures are similar to daezra in their dietary needs, they can eat both flesh and ash. Many of the lower levels of their foodchain feed on microbes around gas vents or photosynthetic animals, as energy works its way up things start to get big and mean.

Hellhound
We don't know its daezric name so we just call it a hellhound. These things were actually endangered, their sheer size makes finding enough food difficult for them. Until they found earth and all the new things to eat, they've been spreading pretty uncontested in russia and europe. Though in africa and asia some other big wild life have been holding them at bay and they can't cross the middle eastern deserts. They're not very complicated animals, securing food through a mixure of sheer bulk and the ability to spew fire. Their actual greatest natural predator are some of the naraxan wildlife that keep sneaking up on them, which they're not used to. Daezrans have a few tame ones they use as siege beasts from time to time.

 

 

 

 

 

 

 

 

 

 

Cabra
Its an herbivorous herd animal that can often be found roaming around eating plants. While not carnivorous it is big, mean, and territorial. If it doesn't consider you a threat it'll generally leave you alone though the males will form war parties to protect the herd. Running away is a good choice since these males often charge with intent to scare you off rather then eat you. Though they have been known to sometimes invade human settlements in prime grazing areas to try and take over the territory.

 

 

 

 

 

 

 

 

Tyrasgal
The tyrasgal is 40 feet tall. They have camoflauge abilities to hide their massive size to get closer to prey at which point they can burst into a sprint of up to 120 mph. They don't really pay much attention to humans unless we get too close because we're not worth the expense of energy required to eat unless there are a lot in one place. They have evolved a number of mechanisms to fuel themselves to compensate for their sheer size. They are omnivorous, photosynthetic, radiation and thermal powered. Basically if there's energy to be had, they have a way to collect it. This actually makes them more docile then you would expect because they just want to find the easiest source of food. If you're running all over the place trying not to get eaten they might decide its too much effort and go find something either bigger or more stationary. Unless they're tamed by some daezra, then they're a siege weapon.
