SomethingUncommon

Not sure how uncommon you're looking for, but I think I already did this.

I chose Sage.

According to some quick googling (read: not sure how accurate this is), Sage wasn't in the top 500 names for my birth year, but my given name was top 100.

Though both names I've used have been trending towards more common for most of my life. Looks like my original name is now a top 35 most common, but Sage is still outside the top 100 for females and outside top 300 for males.(Really wish there was more data for the popularity of nonbinary names. I think Sage is probably one of the more popular enby names, so maybe it's not all that uncommon, depending on how you define it.)

Something old, like a name from Sumer, Akkad, Elam, maybe something Hittite.

Epirmupi, Shamsaki, Puzur-Inshushinak, Ninurta, Lugalzagasi, Tiglath-Pileser, Hattusili, Suppiluliuma.

I'm loving the creativity here! To me though, "uncommon" implies that it's not like completely unheard of either. so, my choice would be "Midge"

Dekkia.

I already use that name everywhere online, might as well put it on my passport.

Nebuchadnezzar. It has an air of nobility about it and no-one would be able to spell it, ever.

My username is my first name, and I'd say it's already pretty uncommon!

New full name: Theophrastus Bombastus

Batman bin Suparman

Common, the Rapper.

Not to be confused with Common, the rapper

I always thought Ziggy was a cool name.

Biggus. Now guess what would I change my last name to.

the ascii null character

Jimothy

Belize

I always thought that Fox was a cool name for a dude ever since I watched the X-Files. If I had to change my first name, that's what I'd pick.

Throckmorton. Saw it in an example problem in my highschool physics textbook and I still think about it

Puck like Puck from A Midsummer Night's Dream

Reason: that'd be hot

"nil" or "null"

I already did, but I won't be sharing it in a public forum :P

Doesn't apply for me, but nonbinary folk are great for this question because they all name themselves after random inanimate objects (which is 100% valid)

Zach, short for Zachariah. Variation of my fursonas name Zachary (well, technically Zach because he prefers using that over the full name).

Also the name of a Fire Emblem Heroes character I totally want to get more screen time because I think he's cool, as a casual.
