Snover (the Frost Tree Pokemon) is an uncommon Grass/Ice-type Pokemon found among icy mountaintops within the Sinnoh and Kalos regions. Surprisingly inquisitive and isolated among Grass-types, Snover are adorable creatures that can fight back with considerable strength in battle despite their small size. You probably won't see many of these creatures in the wild, but if you do, chances are that you'll end up seeing far more than just one; it may sound cute at first, but you would be surprised how awkward it would feel to be hiking and suddenly have five or more of these strange plants staring at you in the middle of nowhere!
Snover are the only species of Grass-type Pokemon that are adapted to the cold and enjoy living in what may seem like a nightmare to other plants. Believed to have originally descended from an ancient type of pine, Snover and their evolved form Abomasnow are completely unique to the Sinnoh region, having developed in isolation among the region's icy peaks and frozen plains. As such, their lifestyle has been the subject of much study and research over the past few decades. Snover are able to survive in their freezing habitats by using fine hairs on the bottom of their root stumps (their feet) to warm the snow and ice below them into a liquid that they can them suck up and extract nutrients from. Snover have adapted to the cold so well, in fact, that they do not use photosynthesis to produce energy but a slightly more advanced form that allows them to survive solely on the energy obtained from breaking down complex impurities within the water they drink. This also allows them to actually lower the air temperature around them so much that it facilitates the crystallization of water vapor, transforming even a sunny day into a blinding hailstorm; this particular Ability, known as the Snow Warning Ability, is completely unique to the species and Abomasnow but is generally only an issue when outside cold environments in the case of Snover. Unfortunately, this has made the species extremely wary of warmth and virtually impossible to take care of outside of a fairly cold environment; this also means that the only time Snover will move out of their natural territory is when spring comes, in which case they will move to higher elevations in order to remain as cold as possible. Interestingly enough, though, the coming of spring still triggers the production of fruits among the species, resulting in the formation of small berries that quickly become frozen from the cold temperatures. The seeds within them are hardy enough to survive this, though, so the reproduction of the species has never been a serious issue; moreover, the berries actually taste quite sweet when frozen (but are normally goopy and bitter when warm), so they are often times a popular treat among tourists and are generally given by Snover to strangers they find lost within their territory until some form of external help can arrive.
The fact that the Snover family has effectively developed in complete isolation among the few other species that occupy the Sinnoh region's colder areas has left them with almost no knowledge of the outside world; needless to say, then, the sudden appearance of humans was likely quite a shock to them. While other creatures and even Abomasnow saw humans as a threat and merely tried to avoid them at all costs, Snover quickly became enraptured with the strange beasts and started studying them intensely. To this day, wild Snover still seem to hold an intense curiosity towards humans and more often than not will follow just about any set of human-like footprints in the snow in hopes of finding a subject to interact with. In practice, this can lead several or even entire hordes of these plants to follow said footprints for hours and even days in the hopes of finding a person, which can in turn generate quite a surprise for any person they actually happen to be tailing when they catch up. Thankfully, Snover seem to bear no ill will towards humans, nor do we bear any to them, so the history between our two species has been little else other than peaceful as far as written history goes back.
While they might be unable to survive in anything less than freezing conditions, Snover are hardy little plants that will gladly give it their all just to please their friends. Their very existence and powers might scream unconventional to the traditional fighter, but with a little practice and patience, these strange pines can easily be made into worthy combatants in any battle. If anything else, you can at least see them as a bit of a saving grace if you find yourself lost in the coldest reaches of the Sinnoh region; you might not be able to make it to the safety of the outside world ever again, but it's unlikely that you'll freeze to death without at least a little company by your side!
