Im sure I missed a couple
Some mad woman pretending to be the devil
A Long dead queen/goddess who possessed data
Another (different) Q
the care taker
Lots and lots of Q
there are a fair few
The funny thing about all these godlike beings (post TOS anyways) they all start out as technological beings, and then steadily grow into supernatural ones instead. Early Q clearly travels in a starship, he stops the enterprise with a device of some sort, beams in and out, beams the crew away to his trial.
The Wormhole aliens are just that, wormhole aliens. They use the orbs as probes and transport vessels, but it is clear they are still beings grounded in reality.
The Care Taker was a friggin blob like being in a spaceship.
Then the series goes on and they become more and more supernatural, and that just bothered me a little.
