It’s important to note that this isn’t simply anger but rather aggression born from fear. The importance of this distinction is simple: if it were simply anger, then all you would need is to teach your kommo-o calming techniques. However, because there is clearly an element of fear to its behavior—or at least I gather that there is, judging by its reason for being aggressive towards a particular species—then you would need to address that fear specifically.
Granted, yes, it’s also important to help your kommo-o deal with its aggression in a positive manner by training him to calm on command (Tip: Use positive reinforcement to teach your kommo-o to heel. Reward your kommo-o each time you tell it to heel and it sits or otherwise remains still. Combine this with extra training to let out pent-up aggression), but that’s simply step one of a longer process.
Once your kommo-o learns how to heel and calm itself in high-stress situations, you’ll need to begin exposure therapy. It may be worth it to catch or breed your own wimpod to give your kommo-o regular exposure and thus consistent training; otherwise, set up a regular schedule with your friend. Either way, have your kommo-o interact with a wimpod in a comfortable setting. Begin with a short time period (and have the wimpod’s poké ball in hand) and be firm and quick about heel commands. Also be sure to reward kommo-o every time it holds back instead of outright attacks wimpod to reinforce the idea that it can have positive interactions with members of the wimpod line.
You’ll notice that I avoid telling you to help your kommo-o train and defeat a golisopod. While some trainers prefer doing this, the truth is that this avenue carries a lot of risks. It could help your kommo-o get over their latent fear of the wimpod line, yes … but it could also teach your kommo-o that wimpod and golisopod are easy to bully. It’s far safer to promote positive interactions and to help your kommo-o master its aggression.
Unfortunately, as a partial fighting-type that, in the wild, spars with other hakamo-o to hone their skills, your hakamo-o is responding to the instinctual drive to better himself through fighting. It just so happens that your pyukumuku, being a pokémon that doesn’t normally move on his own, is an easy target in your hakamo-o’s eyes.
I would highly suggest increasing the amount of time you train your hakamo-o. Allow him to spar with your other pokémon if you don’t already, and increase the amount of time he spends sparring if you do. Also consider allowing him to battle against other trainers’ pokémon. The goal here is to satisfy his daily need to spar—basically, his daily need to let off steam. The more active he is, the easier this will be.
Luckily, when he evolves once more, he may calm a bit more. Kommo-o are territorial and prone to intimidating others, yes, but they prefer to intimidate over engaging in battles with just anyone.
I’ll answer both of these at once, as taking care of both lines is actually astoundingly similar.
In many ways, taking care of jangmo-o or axew is a lot like taking care of any other reptilian pokémon. For one, temperature is important, especially in the case of the tropical jangmo-o (although axew also shy away from cold as well). Thus, always be sure your jangmo-o has a flat rock for sunning during the day and hiding beneath at night. For axew, be sure you have a shelter with nesting materials (such as straw) for nights and a clear space for sunbathing during the day. In colder weather, move both pokémon indoors and provide them with enough space to roam about and a sunlamp. As both are mountainous and cave-dwelling pokémon, they don’t need much more than that to sleep on, so beds aren’t necessary.
Also, be sure they both have clean water dishes, and change this every day. Likewise, line their enclosures with poké litter or straw and change this often. Both axew and jangmo-o, being reptiles, are at a high risk for carrying nasty bugs such as E-coli and salmonella, so changing their enclosure linings frequently minimizes the risk of allowing diseases to spread to you or your other pokémon. Grooming consisting of giving them warm baths every so often further minimizes this risk and, in the case of jangmo-o, helps polish pokémon scales.
As with most dragons, jangmo-o and axew are also primarily carnivorous, but their diets can be supplemented with leafy greens and berries as well. Cleaning their enclosures also removes stray food and prevents rot (especially if you choose to supplement their diets), but when your jangmo-o or axew lives outdoors, you can easily sweep these to an inaccessible corner for easy composting.
When it comes to toys, while they do enjoy chew toys and bones, many axew and jangmo-o do just as well without them. You may even find that your dragons will prefer exploring their environments or sunning to occupying themselves with objects. In a way, this means they’re a little bit more of a challenge than most pokémon to satisfy in terms of enrichment, but that’s where the battling part of their lives come in.
You see, in both cases—but especially jangmo-o’s—it’s necessary to train and battle with them, even if you don’t claim to be a trainer. Even setting up a training dummy would be sufficient, but ideally, you should set up sparring matches between your dragons and other pokémon, as well as create specialized training exercises to develop specific attacks or skills. Either way, it’s important to keep in mind that unlike many other pokémon, battling is mandatory for them, else they won’t be able to develop the skills they need to survive later in life. For example, although haxorus are gentle pokémon, fraxure most certainly are not, and the fact that they aren’t is both the contributing factor to why their tusks are so long and sharp as well as their main method of keeping them pared down to a reasonable length. Hence, training axew from an early age and instilling a strict regimen of fighting and battling allows it to build up the strength, skills, and endurance needed for proper battling as a fraxure.
In a similar manner, jangmo-o comes from a line that eventually gains the fighting element in its more advanced stages. Additionally, just like fraxure, both hakamo-o and kommo-o are well known for their battling prowess and their predilection to battle each other on sight. Thus, a battle regimen is in a way especially important to jangmo-o, as battling is essentially a part of its nature.
Here’s where the two species diverge, however. While axew and haxorus may be able to get along with their own kind, fraxure actually cannot, as the fraxure stage represents a departure from one’s birth nest to lay down the groundwork for their territory and breeding nest. Fraxure see one another as competition for the same territory, so keeping multiple fraxure of the same gender may get complicated. By contrast, jangmo-o are a more tribalistic species in that they form groups that are highly dependent on one another. Raising multiple jangmo-o is thus sometimes preferred, as members of the jangmo-o line feel most comfortable battling one another. On the other hand, members of the jangmo-o also get particularly enthusiastic about battling one another, so a match between two or more jangmo-o may be just as destructive and violent as a match between two or more fraxure.
In other words, always hold your dragons’ battles outdoors.
Jangmo-o The Scaly Pokémon Type: Dragon Official Registration #: 782 Entry: A small, dragon-like pokémon native to the rocky canyons of Alola’s Poni Island. Although they look fierce, jangmo-o are actually highly timid pokémon around anything but other jangmo-o. As a result, they reside deep within Poni Islands’ cave and canyon system, in rugged terrain that’s very difficult for most humans and pokémon to traverse. There, they train against each other, bashing into one another with their rock-hard crests in order to harden their hides into steel-like armor … which of course is perhaps not the most advantageous thing they could do to preserve their reclusive lifestyle, seeing as the sound of one jangmo-o bashing itself against another jangmo-o produces a loud clang that resonates throughout their native cave system and thus alerts any possible outsider to their nests’ specific locations, but who is the author to judge?
Hakamo-o The Scaly Pokémon Type: Dragon/Fighting Official Registration #: 783 Entry: The evolved form of jangmo-o, by battle experience. As this pokémon grows, it sheds its scales. Through this process, each hakamo-o develops a coat of scales that grows harder and sharper with each subsequent shedding. On a hakamo-o, these scales are invaluable and become integrated in their owner’s vicious, physical techniques. Their sharp edges can serve as weapons in a pinch and can inflict lacerations upon the slightest touch, especially as hakamo-o grows older or nears evolution. Off of a hakamo-o, however, they’re either great for slicing vegetables or a fantastically easy way to earn yourself a visit to one of Alola’s many lovely emergency medical facilities, depending on whether or not you were able to spot these shed scales before stepping on them.
Kommo-o The Scaly Pokémon Type: Dragon/Fighting Official Registration #: 784 Entry: The evolved form of Hakamo-o, by battle experience. In order to intimidate any enemy it spots, kommo-o vigorously jingles the metallic scales on its tail. The author assures you that when facing a five-foot tall, 173-pound dragon that can either maul you with its claws, throw you, or slice you in half with the aforementioned tail, this jingling is a lot more intimidating than it sounds.
