Pesky Dust for instance can enter dreams and is basically all powerful in them, but there could very well be some limit or way to turn the tides in the same way Ben did when Enoch was invading his dreams(not with the same powers as Pesky Dust mind you). And against a powerful unrestrained foe you're probably not going to get them to sleep all that easily; even with the fairy dust I'm sure a lot of people could just tank that without effect. But could Pesky Dust best some sort of god figure in their own dream if they do something like sleep? Unconfirmed.
Whampire's hypnosis is what you're talking about I'm guessing. That's kind of on the weaker end of crazy stuff. Toepick's power is pretty potentially crazy, though Omniverse had to ruin it in the Ma Vreedle episode by making her immune, which is a gigantic antifeat for the alien. There's also the matter of "just close your eyes nigga" being a perfect counter. But yeah, he can apparently make Celestialsapien personalities scared, at which point they can't vote on anything and you could Jetray express them into Anur Vladis. But they might get so scared that they reactively agree to wipe you from all of existence immediately so they're a slightly bad example.
Some more situationally ridiculous transformations: Big Chill, Ghostfreak, Jetray, NRG, Chromastone, Echo Echo, Upgrade, Grey Matter...Clockwork. If you want to go off of what the show demonstrates alone(which really downplays what Celestialsapiens can do) then Clockwork restoring the timelines was arguably a bigger feat than Alien X's. If Maltruant wasn't so full of himself he may have very well been able to kill everyone.
