I can't find the creator of this fan character, but I know its name.

"Swing." - the arachnid-like Guardian Spirit.

I know the image's artist didn't create them because of the comments on the source post (https://x.com/SaphiraButNSFW/status/1806729886725214221) (or https://xcancel.com/SaphiraButNSFW/status/1806729886725214221 if you don't have an X account)

So, how do I tag this fan character?

My first guess was swing_(unknown_artist), but the character's owner might not be an artist.

"oc belongs to 图牙"

I'm looking around to see if I can find any accounts owned by this "图牙", but I'm not having much luck.

this other post by the same person romanizes the name as "Tuya", so swing_(tuya). but I'd still prefer an actual look at something of the dude's online presence.

(to answer the question posed, if the character owner is unable to be found, I think <name>_(<species>) is probably the way to go untill the owner can be identified)

EDIT: there

图牙 -> Tuya (Romanization) for literal translation of "tooth diagram"?

Most of the English replies call them 'Tuya,' yeah. I really hope they're l3534795389328.

Thanks for the help, both of you!
