The tag alias #70966 nav -> nav_(disambiguation) is pending approval.

Reason: Several characters and copyright holders going on here.
On a related note there's kiba_(nav), kiba_the_skunk_(nav), and kiba_the_lion_(nav). I don't know for sure what's going on here- if these are two characters owned by the same person with the same name, one character with an alternative species form, or something else, but this could probably be cleaned up and have implications or aliases.

you're gonna have to change the consequent tag's category to invalid too

The bulk update request #8360 is pending approval.
