Wandered across post #1437175 where a character was mistagged. Was tagged with character tag group17 (see footnote-1), but character named Commodore ... so changed tag for that upload from group17 to commodore_(group17).
While looking for other images of Commodore character i found post #1413397 which is tagged with commodore_dea_v2.5 (currently e621 has as a character tag)
I suggest the character tag should be commodore_(group17) because
1) most of the uploads for character just refer to him as Commodore
and
2) https://www.furaffinity.net/view/25733742/ says "Commodore DEA v2.5 units" which makes Commodore DEA v2.5 a species of sorts (synthetic species) ... so maybe commodore_dea_v2.5 could be species tag instead of character tag.
***
by the way,
10 uploads at FA with Commodore and DEA https://www.furaffinity.net/search/?q=commodore+dea (seven in group17's gallery)
33 uploads in folder https://www.furaffinity.net/gallery/group17/folder/490080/Commodore

footnote-1 = group17 tag was a mix of some of group17's characters. Maybe change group17 tag from character tag to copyright tag?
Group17's main character apparently "Halogen "Group17" Greaves" (according to https://www.furaffinity.net/user/group17/ ),
so tag that character as halogen_"group17"_greaves ?
