I’d like to answer all of these asks at once for the sake of saving time. Many of these asks have very similar responses: I don’t have enough context to know for certain why your pokémon are arguing or lashing out at teammates (or guests, in the case of the above mentioned sylveon).
You see, a pokémon is never aggressive for no reason, but that reason is entirely circumstantial and dependent on a wide variety of factors. So the first step is to observe your pokémon to determine a trigger. Sometimes, it’s jealousy—a pokémon becomes jealous of another or of a human you’ve chosen to spend more time on. Other times, it’s simple personality conflicts, a personal dislike of each other, competition for resources that are actually less abundant than you realize, or anxiety over a new person or pokémon.
In each case, it’s important to find out what the specific cause is by observing your pokémon carefully. Read its body language, see what it and its target are doing just before violence breaks out, and see if there’s anything in particular that seems to provoke your pokémon. Consider also simply communicating with your pokémon and asking them if they can tell you what the problem may be. Although pokémon can’t often literally speak to us, they’re highly intelligent and may be able to indicate what’s upsetting them with gestures, barks, or simply by showing you.
Once you determine the cause of the issue, it will be far easier to resolve it. If two pokémon are arguing, serve as an objective mediator by suggesting compromises. Couple this with increased double training off the battlefield (that is, train your pokémon together outside of battles and have them perform tasks as a team) to strengthen teamwork.
If a pokémon is aggressive towards another who isn’t reciprocating, be sure to introduce them slowly, rather than at once. Set up a comfortable environment and allow your pokémon (both the aggressive one and the target) to enter this space, first for a short period of time and then over increasingly long periods until your aggressive pokémon can tolerate being in the same room as the other. (You may wish to teach your pokémon to heel before this.) Yes, even if your pokémon has never displayed aggressive behavior towards other members of your team, it may be worth it to go through this process with it and its target anyway. Think of it like meeting a new person. You may not like everyone you meet, or you may have gotten a bad first impression. However, if you’re in a comfortable atmosphere and you’re asked to interact with that person, the more you do this, the easier it will be to tolerate them.
If a pokémon is aggressive towards a human, it’s important to pay attention to why, especially if your pokémon is psychic or an absol. (The one in the above asks is not, but even so, this doesn’t rule out the possibility that your pokémon is sending you a warning.) If your pokémon is acting out of fear for either you or your safety, promise them that you’ll take their warning into consideration but reassure them that they don’t have anything to fear, especially if you know your human company well enough to determine right away whether or not such fears would be unfounded. If, however, your pokémon seems to be jealous or seems to dislike a person on a personal level, teach your human guests the best ways to interact with your pokémon partners and have them do so (cautiously at first). Let your guests feed your pokémon treats and play with them as you would. Allow them to connect with your pokémon as friends. All the while, reassure your pokémon that you’re not replacing them with human contact.
In each case, the point is that aggression in pokémon sometimes happens, but it never happens for no reason. It’s up to you as a trainer to determine what that reason is and to take steps to alleviate it, depending on what the specific problem may be.
Best of luck to all of you!
