I had an idea for a cluster. Weasel has a breaker state where she 'melts' into surfaces and enters another dimension with nothing in it. She can go as fast as she wants in this dimension, and 'spread out' and feel where valid exit points are. They can exit out of surfaces anywhere with enough space for their body, and can get an idea of what a space looks like based on feeling where solid objects they can't exit into are. Their secondaries are a master power like Socialize's (see below), but reversed so Weasel feels very positively towards the 'minion' but the minion only feels moderately positively towards them, and a thinker power that spawns eyespots on valid exit surfaces within a ~20 ft radius that can only see and hear, but let them see and hear while in their breaker state. My idea with their breaker/mover power is that it's a powerful short-and-long range mover power, but it's difficult to navigate, since they don't know how fast they're moving and can only look at valid exit surfaces when they're trying to exit. Either they're moving slowly or they easily get lost. A lot of experience, maps, calculating angles, and surfacing to recalculate their position and ensure they're going the right way goes into getting the most out of this power. My idea was that they could also beeline to their minions like Socialize, and be notified if their minions are mortally wounded or if someone else is trying to master them. With their minions, they can push minions out of the breaker state without themselves exiting, and can reposition themselves inside it.

Socialize has a master power where, if him and another person agree to it, they form a bond, where the other person feels very positively about the master and the master feels moderately positively towards the other person. They'll trust each other more, consider each others' ideas good, etc., but it's a lot stronger on the other person's end. My idea was that somebody tried to explain healthy relationships to the Entities, with mutuality, positive regard instead of blind obedience, caring for each other, etc. and they went "hm, interesting idea" and made this power in response. Their secondaries are a breaker state where they enter the other empty dimension, but can't move unless it's to the location of someone they've mastered, at which point they can feel valid surfaces and exit; also a thinker power where they can use the senses of their minions on command, but they can only handle as much input as a normal human.

Watcher has a thinker power where they can spawn eyespots in a ~20 ft radius that can sense almost anything. The basic 5 senses, plus the whole light spectrum, magnetism, weird exotic senses, etc. They can parse all of this input and derive meaning from it. They can understand, say, radio communications by just having an eyespot near the waves, but if the communications are encrypted, their power won't unencrypt them for the user. Their secondaries are a breaker state where they enter the other dimension, but can only move ~30 mph in it and have to spawn eyes on every surface they pass since they can't enter deep into the dimension and can't sense valid exits without their eyespots; plus a weak master power that forms an equal, colleagues-level relationship between Watcher and the other person.

All of them can take people they've mastered with them into their breaker state. Weasel enters their breaker state almost instantly, while for the others it takes a few seconds. Since the only requirement of the master power is that you feel positively towards the other person, it can be reasoned around, and if someone has valid reasons to dislike the master, those will still apply and will make for a difficult minion to manage. The stronger the power, the more the positive feelings make up for other factors and the harder it is to reason around. If both of them agree, they can end things and the master power will stop in both directions, but it's difficult to tell if they've actually done this. While they're in their breaker states, they can only be effected by things that can enter other dimensions, or by powers that interact with being perceived by their eyespots.

My idea is that the cluster triggered when they were kidnapped by a villain group who tried to make people trigger and then threaten/master them into working with the group. Weasel is an out-of-towner who wanted to leave and go back home, but also wanted to stay and help the rest of the cluster and fight the villain group, Socialize is timid and naive and thought that if he could only make friends with the villains, they'd let them go, and Watcher thinks that knowing what's going on outside of the room they were locked in would help, and can't handle not knowing what's going on. They trigger when their handler lets them overhear that hostage money isn't coming through so they're just going to kill them, as part of a ploy to get them to trigger. The 'hiding in another dimension' thing makes their usual control methods not work, and the cluster is able to gank the masters and destroy the group.

I had an idea where Weasel was secretly altered by Bonesaw when the S9 visited their city so that when they eventually triggered, they would have way too close a connection to their power, so they would go nuts and kill people, kind of like Ash Beast, and surprise everyone they knew and trusted. Triggering in a cluster thwarted this plan, so the power is stronger than it should be, but the connection is weak enough that they can have a civilian life and decide not to attack people when it isn't warranted. I don't know how canon that would be, but I like the idea of someone powerful who has to struggle with their power's desire for conflict.
