Maybe for Galactic? The people here seem fairly respectful of Pokemon when they have their spirits intact.

[Who knows why Galactic isn't going after this one, though. Maybe a Pokemon that controls nightmares isn't exactly something they need when they already control everything.]

I don't know. It's not like I want to go test the idea myself, but maybe it's not something it can control. Like how Uxie looking at you removes all of your memories.
