Went with the last option in the poll, because that's the closest it got to "who cares?". I think a super-powerful entity as a character in a work of fiction has a huge potential for making much of what happens meaningless. Either everything can be resolved super-tidy (in a good or bad way) with little effort or drama, or there are arbitrary reason why it doesn't. Either outcome has its huge pitfalls to step around.
I'm not saying amazingly powerful characters can't be a thing. But I don't see how they apply to QC. You could have a character that's just too apathetic to do much (like Dr Manhattan). But that's honestly super-depressing, and works best for deconstructions and very cynical works of fiction. You can scale everything up (like Superman stories), but QC is charming in large part because it's slice-of-life, so almost by definition low-importance, local, low-stakes-in-the-grand-scheme-of-things-stuff. Y'know, normal people problems, just with robots.
You can explore the nature of power and humanity and go all philosophical, but I'm not convinced that works as a side theme of a story.
And as someone pointed out, Spookybot is not dissimilar to Q, but - again, as I think someone mentioned - Q tends to get his comeuppance at least some of the time. He highlights how much potential humanity really does have in the end, which enhances the usual characters in the show and works with ST's themes very well. Spookybot has not given me that vibe, at least not yet.
When I think about what Spookybot might want, I can't think of a single answer that would engage me more than the more mundane goings-on in QC tend to. I don't wanna be a hater, but I have yet to think of a reason Spookybot might work for me. There's plenty of places this character might go, but all that I can think of (the ones I listed and perhaps a few more) just clash with the comic's usual shenanigans. I think I might happily read a Spookybot-centred story *apart* from QC, in the right circumstances. But for QC specifically, I'm afraid it'll steer away from what made it charming for me in the first place.
