Eevee
Mutatiovulpes octuplumiter
Overview
Eevee have experienced an astounding rise in popularity over the past quarter century. Previously they were an unpopular species confined to a dwindling range in Europe. Now they are consistently ranked as one of the most desired pokémon in the world. Before eevee ownership was mostly limited to scientists working with radiation or attempting to unravel the secrets of pokémon.
Currently pokémon science is mostly limited to figuring out how things work. There are eighteen (or so) variations of elemental energy and every pokémon links better to some parts of the spectrum than others. Moves are similar patterns of energy use employed by multiple pokémon, even those without the anatomical support for such an attack. Flash evolution occurs in some species but not in others for reasons unknown. Eevee, with their multiple elemental evolutions and high sensitivity to radiation, might be the key to beginning to figure out why things work instead of just how they do. Or they might not. Research so far on the species has not actually answered any of the biggest questions scientists want answered.
In the meantime, eevee became one of the most popular pokémon in the world thanks to a few well-placed coordinators and pop stars as well as a TV series about a bandit in the American Southwest. Some eevee are cute, although their mutations can easily trigger the uncanny valley effect or make them outright disturbing to look at. Its evolutions are at least more genetically stable. As breeders have bred more and more eevee to keep up with demand the species has become a popular alternative starter for even middle-class families. One starter can potentially evolve into one of eight forms down the road, letting the trainer figure out what they want once they have actual experience working with pokémon and a vague idea of what their final team will look like.
Eevee are generally friendly. They are also not nearly as mischievous as most other foxes. Trainers willing to put up with their health issues until the pokémon evolves may find one to be a rewarding companion.
Physiology
Eevee are classified as normal types. Some have a very deep connection to this element and can charge their attacks with neutral elemental energy. Others have no particular affinity. Eevee can also take on the traits of different types as they age, even before evolution. Normal is a sort of a placeholder typing in most cases.
Eevee are vaguely canine quadrupeds. They usually have brown fur, although variants with white, black, silver, red, and even blue coats have been observed. The average eevee has long pointed ears on top of their head. Their eyes are typically large and front-facing. A mane of light-colored fur covers their neck. Their bones are usually lighter than the average dog pokémon but sturdier than the average feline.
It is hard to be more specific when discussing eevee because of their most notable quirk: rapid mutation. The same ability that lets eevee evolve into at least eight different forms also means that their appearance and anatomy are constantly in flux. Traits from nearby pokémon and even humans can be gained or discarded over the course of the pokémon’s life. An eevee raised primarily around furfrou will gain a very fluffy coat, while one that grows up in the presence of reptiles may gain some crude scales. There are many reports of an eevee’s face coming to resemble that of its trainer. The resulting face can be cute, awkward, or disturbing.
Eevee lifespans are variable. Most do not live past two years in the wild or captivity. Those that grow up around extremely long-lived pokémon can live for up to ten years without evolving. In any case, evolution increases the pokémon’s lifespan.
Size and weight are also variable. Most eevee grow to be around twenty-four inches long, including the tail, and weigh around ten pounds. Some are heavier, some are lighter.
Behavior
Eevee are generalists by nature. They can eat insects, small mammals, fruits, and fungi. Their exact diet depends on the local conditions. Most are good at climbing and digging but struggle to swim. Those in coastal areas may sometimes become strong swimmers as they age. In fact, behavior patterns, from sleep cycles to diet, vary considerably by region and parentage.
Eevee spend most of their early life under the protection of their families. Childhood experiences depend on the exact parents. This applies to the evolution (vaporeon raise their young kits in dens only accessible from the water, espeon build nests in trees) but also to the evolution’s mate. In most species crossbreeding is rare in the wild. Eeveelutions crossbreed about as often as they mate with other eeveelutions. Some of the other parent’s natural childrearing practices will be incorporated as well.
Wild eevee are usually shy around humans. This comes as a shock to many trainers as captive eevee are generally quite friendly and will actively seek out affection. They have been selectively bred for these traits. Wild specimens are not so quick to trust and will sometimes be wary of trainers they have known for months or even years, only coming close to accept treats. The explanation is relatively simple: eevee are a prey species and humans are a large, unfamiliar creature. Against most predators eevee’s best defense is to remain hidden. If that fails they will attempt to run, dig, or climb away before resorting to combat. Most wild evolutions are similarly wary, with espeon and sylveon as notable exceptions.
Husbandry
Eevee can eat a wide range of items. Live insects and raw meat can be the staples of a diet. So can fruit and nuts. Ideally there would be some mix of both, with emphasis on the items the teammates primarily eat. Cat and dog kibble can also work, with occasional raw meat thrown into to provide taurine. Any meat will do. Some eevee enjoy maize as a food that is somewhat difficult to eat (and can be wrestled by small eevee).
Captive-born eevee are generally affectionate. They will follow their trainer around and crave cuddling, playing, and brushing. Some are very fond of sitting on their trainer’s upper back or head whenever they bend forward. Wild-born specimens, as mentioned above, are usually content to watch from a safe distance.
Eevee scentmark their territory. They can be trained to only mark outside but they will still need frequent walks or they will begin to pee on everything they find and consider to be theirs. Eevee also naturally have a distinct scent. This can be somewhat reduced with fox-specific grooming products but will probably not go away. Eevee are also fond of making caches of food in secluded places. Sometimes they will get back to this food before it rots. Sometimes they will not. Trainers will need to either watch their pokémon eat or do frequent inspections of their territory.
The ideal outdoor enclosure for eevee has a variety of places to explore. There should be opportunities to climb and dig. Boxes just big enough to fit in are excellent toys and hiding places. Mulch attracts insects, which are excellent prey and/or toys. Plants give shade and interesting scents, as well as drawing insects. Oleander, however, can be toxic and should be avoided. Slides are also an excellent toy. Jury-rigged water slides are twice as interesting.
Eevee are social creatures by default. They should be provided with some sort of companion at most times, either the trainer or a teammate. Wild-caught eevee will prefer playing with other small-to-mid-size mammalian pokémon. Captive-born eevee prefer attention from their trainer.
Eevee have an unfortunate habit of seeking out radiation of all sorts. At its most benign the impulse manifests as sitting in direct sunlight for hours at a time. Sometimes they will also seek close contact with microwaves, which double as box-like hiding places. Take care to ensure your eevee cannot get in. In the worst case scenarios eevee will attempt to run away to uranium mines or nuclear power plants. Trainers near these areas will need to take great care in building their eevee’s enclosure to make it escape-proof.
Illness
Eevee have inherently unstable physiology. This makes them versatile pokémon that can adapt to almost any environment and evolve into at least eight different forms. It also saddles them with less useful adaptations. Eevee are particularly prone to cancer due to their unstable genetics. Even if they do not get cancer the growth of new traits from nearby pokémon can sometimes mesh poorly with existing ones. Regular checkups are required for eevee, even in mutation-resistant specimens. Eevee are drawn to the radiation in some medical equipment and will gladly go to Pokémon Centers to investigate.
In addition to their more unique problems, eevee still suffer from some of the same issues as ordinary mid-size omnivorous mammals. They must receive a rabies vaccine within two weeks of birth or capture and then again every six months after. Eevee’s rapid changes can sometimes render old vaccines ineffective or lead to new ones being required, such as avian flu if the eevee has picked up adaptations from birds on the team. Eevee will also need regular deworming and anti-flea medication as long as they are allowed outside on a regular basis and have not developed a means of naturally combatting parasites.
Evolution
Eevee can evolve into at least eight different evolutions. Covering all of these in one article would be impractical due to the length of the resulting entry and the differences in care requirements between all eight. The requirements for triggering each evolution will be discussed in the articles for each.
Some eevee cannot evolve. A handful of breeders have been selecting for eevee with less mutation potential. In minor cases the eevee will have a deeper connection with normal-type energy and more resistance to adverse mutations, in exchange for higher thresholds for evolutions. A few of the resulting eevee cannot evolve at all but are also highly resistant to all mutations. Cancer has not been observed in so-called static eevee to date, although the small sample size makes it impossible to draw broader conclusions at this point. Static eevee also seem to have some enhanced connection to the eight elements that a normal eevee could specialize in upon evolution.
In Galar eevee can gigantamax. The process increases the size of eevee’s mane and appears to make them more playful, something that is extremely dangerous when the pokémon is upwards of ninety feet tall. Gigantamax is legal in Galar within stadiums built to handle the unique challenges associated with the phenomenon. It is impossible everywhere else.
Battle
Eevee are versatile pokémon, but they are not particularly strong ones. Sometimes they can compare favorably with other pokémon their age, but if they do not evolve they will find themselves quickly falling behind on the second island of the island challenge.
Eevee bred to have a deeper connection to normal energy are the most dangerous in battle as their take downs and even quick attacks can do serious damage. Other eevee must rely on a mix of weaker normal attacks, coverage moves, and options like sand attack to gradually wear an opponent down.
Alternatively, eevee can use their wide utility movepool and decent durability to act as a cleric. The combination of wish and heal bell can keep the team healthy or be used to heal up the eevee itself. Wish can be difficult to teach, but a teammate that knows the move can greatly accelerate the process.
Finally, eevee have access to a unique Z-move in Alola, Extreme Evoboost. When used the Z-move charges the eevee with energy from across the spectrum, dramatically increasing its defenses, offenses, and attack. This boost can also be baton passed to another pokémon. At least one trainer has combined the Z-move, a static eevee, baton pass, and a sweeper to good effect. The first problem with this strategy is that it requires using an eevee. Even static eevee lag well behind most adult pokémon. Obtaining the necessary Eevium-Z is also difficult as only a few are in existence. The Tapu and Lunala can apparently produce more by converting more common Normalium-Z crystals, but they are difficult to contact and not prone to answering small requests.
Acquisition
Eevee can be purchased from most high-end pet stores. A few breeders on Akala also regularly produce litters. A few escapes from these ranches, combined with releases of undesired evolutions, has allowed for a small but stable feral population to establish itself in central and northwestern Akala. Capture is currently limited to one per trainer. The rule is not based on environmental protection as eevee are invasive. Rather, it is to keep the wild population as a tourist attraction. The Commonwealth government has openly discussed releasing eevee on Akala to bolster the population’s numbers.
Eevee can be purchased, adopted, or captured with a Class I license.
Breeding
Every evolution creates and raises its children in a different way. These topics will be discussed further in the articles on the individual evolutions. Instead, a brief overview of the care of orphaned newborns will be given here.
Sometimes eevee are orphaned, rejected, or otherwise taken from their mother before the point of self-sufficiency. They can still survive with human intervention. The first two weeks before the eevee opens its eyes are critical. A warm, secluded place must be provided. A popular setup is a box lined in blankets with a weak artificial heater underneath. Other pokémon or at least plush replicas should be provided for the eevee to cuddle. Eevee will accept milk from more or less any mammal. Miltank milk is the cheapest and contains all necessary nutrients, although the eevee might overindulge and put on too much weight if allowed. In any case the baby fat will probably be lost fairly quickly after the pokémon begins to exercise.
Eevee are also very accepting of other pokémon as surrogate mothers. If they are inserted into a litter of other newborn pokémon and the surrogate mother agrees to raise the eevee it will grow up healthy, although its physiology and behavior will be tweaked to match its surrogate mother and siblings. Bottle-fed eevee will need to be regularly cuddled by a human or adult pokémon to learn the scent of its ‘mother.’
Relatives
Eevee DNA is extremely difficult to analyze. More static specimens appear to be related to ninetales and thievul. Some eevee’s DNA can become closer to cats, rabbits, or even fish. Some scientists argue that their closest relatives are not foxes but ditto.
A somewhat more interesting question is where eevee came from and why their relationship to elemental energy is so strange. Most early writings from Europe were lost in the Bronze Age Collapse, the fall of the Imperium, or the subsequent rise of the Church of Life. What we do know is that 3,000 years ago the population of Kalos dramatically declined and a monumental graveyard was constructed south of Cromlac’h. There are different accounts of the event: it may have been a plague, the intervention of Yveltal or Xerneas, or even an ancient weapon of mass destruction.
Some scholars have argued in favor of the last point citing eevee as evidence. They do not appear in any early cave drawings or the surviving records of the ancient world. Eevee and its evolutions also do not appear in the fossil record until approximately 3,000 years ago. Wild eevee also appeared to undergo a dramatic population increase following the invention of atomic weapons and power plants. Perhaps they emerged following a nuclear blast near Cromlac’h.
This theory is undercut in a variety of ways, however. The economic and industrial support network needed to mine the necessary ore and construct the bomb simply did not exist before the Industrial Revolution. Bronze Age Kalos did not have firearms, so making the jump to atomic weaponry seems unlikely. It is also quite possible that the timing of eevee’s rise and the population decline in Kalos is simply a coincidence.
