I would probably fare pretty well.
The rest of existence, maybe not so much~

Though, for real, if all powers/abilities are fair play, then I'd probably spend the entire first day trying all kinds of shit, altering reality, history, etc.
Throughout the first year, I'd probably let more people be their sona, but more within reason (otherwise, the planet would probably be wiped out in moments; that's for later)

For the rest of time? Probably just keeping myself entertained, and likely getting desensitized over time.

I usually pay little mind to micros, but they tend to seem pretty eager to serve my pits/paws/crotch. Guess the musk gets them going.

I'm always up for nanos getting eaten just like micros do~
Though, they'll have a hard time in there when even the gut bacteria is planet-sized to them 😏

I'd usually say clothed. If nude then not the nsfw kind.

Soul vore can take so many forms, and depending on mood I prefer one or the other.
Anywhere from your, essentially ghost, remaining where you last were forever, to experiencing life via one of my body parts for the rest of eternity.

You could even find yourself in a whole new reality of my creation, along with all the others who suffered the same fate. My toys forever, to do with as I please~

Utter domination.
Aware or unaware.
This ranges from intentional teasing about how big/small one is, to just simply flattening a building/city/etc. by accident. The scenario of "this nearly unnoticeable motion to them is a calamity for the smalls"

Infinity can be quite lonely yes. But that's why I tend to enter realities with an avatar to have people to interact with. Lots of scenarios and size fun to be had~

Personally? I tend to enjoy non-graphic digestion that either ends in soul vore or reforming the day after. Though, more often than not I'm open to what the prey is comfortable with.

I'll risk sounding like a broken record and say unaware, since it's the good stuff. I imagine macros just traveling trying to find other civilizations to trade with but never bothering to look at the strange little "stuff" on the ground they keep stepping on. Could also always be to invade and expand their territory... except they are literally crushing the opposition without even knowing it~

So the fate of those little guys would be to be flattened without ever standing a chance, or even being noticed for that matter~

Oh, that fully depends on the size of the micro, I could see them stuck in pizza cheese though~

Unaware in my shoes, I'd say. Either that or having a freshly shrunken micro worship my paws.

Uhh... in essentially just alphabetical order per category:
Arexu - keep
Ciel/Julian - keep
Javier (Javierowo) - keep
Quinn/Threefolder - keep
Mocha - keep
Danathius - nom
Dem/Theo - nom
JetLaudir - nom
Ohkuri - nom
Toki - nom

Not necessarily, there's some musk to be had, but not excessive.
A good bit of hypnotizing musk is hot. But not to the point where you'd say it's actually stinky.

I'll let you keep your anonymity, would take the fun out of it otherwise

Not just your planet, your universe, multiverse, omniverse or reality... whichever you think is the biggest of those. They'll be ground like dust beneath my heel~
