Aliasing バルタン → vartan
Link to alias

Reason:

Google Translated artist name. First tagged as such by N7 on post #483493

Apparently pronounced as "barutan", in case that would be preferred. In which case, there are currently only six vartan posts that would need retagging.

EDIT: "baltan_(artist)" would be more appropriate. Justification below.

As usual, Google fails at translating Japanese.

I figured as much; Seems to happen every time. Probably requires someone with knowledge of Japanese language to translate some of these Pixiv user names.

Correct me if I am wrong: "Alien Baltan" is "(バルタン星人", and the artist is "バルタン" minus "星人", that is just "baltan"?

And if "baltan" alone can refer to the Ultraman character, we should use "baltan_(artist)" for the artist in question?

Again, probably requires someone more savvy than me to decide on this.

Yep, exactly.
It's basically the same 'difference' as ウルトラマン (urutoraman) and Ultraman.

Baltan seems like the best way to tag it, though Barutan would work too; and I agree that the *_(artist) disambiguation might be needed. ...I wouldn't be surprised if someone uploads porn of the species someday. _{^{Though I haven't seen many anthro lobsters here..}}

I've made the following changes:

• Alias: バルタン -> vartan (denied)
• Alias: バルタン -> baltan_(artist) (approved)
• Alias: vartan -> baltan_(artist) (approved)
