While I do not have a true idea down for them, here’s a baseline I’ve had for a while:
Ghetsis. He’s back. And he is not happy.
But rather than just rerun Team Plasma, he’d have long since established rule over a new group. Once again, I lack a name for it. Regardless, it’s not truly lead by Ghetsis, he stepped down at some point and now just oversees it, but it is now instead led by a much more humane character. Unlike Ghetsis, who is completely merciless when it comes to Pokemon, this group is led by yet another person with a Crobat.
But the main kicker of this group is not of their origin, but rather their actions - They’ll probably be the first professional Evil Team the world of Pokemon has seen (at least, in their specific region). The Grunts, while likely much less abundant than other teams, are well-trained with codes, strength, and most of all, Strategy. Doubt the protagonist would get little more than hints about their existence until that first run-in with a Grunt who blundered terribly.
But they’re prepared for a rumble. Remember how Ghetsis used to lead the team? Well, he knows of the threat that a Pokemon Protagonist has. And he’s done his research. One strong child trainer’s a coincidence - Two’s a trend. And both are not only silent, but also children.
And this research is now in the hands of a Leader who cares.
With this in mind, when you run into their base(s), you’ll see many posters up on the walls - Phrases like “Hear nothing? SAY SOMETHING!” and “Silence KILLS!” headline the tops of each one of them, with explanations of problems. Yet all of them have the phrase “SPEAKLOW” plastered somewhere in the words, usually referred to if someone “sees something suspicious”.
And later on, you discover a major problem about it. Remember how the leader has a Crobat? Well, a Crobat means they care about even the lowest of their grunts. So what if they employed a catchphrase to hint towards any drills they might’ve been taught?
Well, enter SPEAKLOW protocol, which you learn the meaning of yourself at some point:
Stop whatever it is you’re doing
Prepare an escape route
Eavesdrop onto the suspect
Alert your higher-ups if threat is genuine
Keep calm
Log any details you can about them
Out yourself from the situation
Walk away, your life is worth more than your job.
My friend, by the time you learn this catchphrase, not only do they know what you look like, but they also know that you are a huge threat. Not just to the job, not just to the team and its goals, but to each and every single member of the team. And now you know why that first Grunt encounter had them nearly at a panic attack.
And with a leader who cares, you know that the whole entire team is gonna do its absolute best to make sure you do not interfere, by any means necessary. And you know that they are heavily trained specifically for the moment they run into you.
From then on, you better watch your back and you better watch it closely - You now need to outsmart a group of professionals at their own game before they either end you or fulfill their goals. And lemme tell you - with Ghetsis involved, even as merely a spectator, those goals will not end well for the world if carried out in full.
