The bulk update request #1063 is pending approval.

create alias jack_the_kobold (0) -> jack_(nonimousmate) (90)
create alias tom_the_cat (0) -> tom_(nonimousmate) (96)

Reason: I'm the artist (NonimousMate) and both are my original characters. All my other OCs are already tagged in the name_(nonimousmate) format, like ignir_(nonimousmate), max_(nonimousmate) and gwen_(nonimousmate). These two were the exceptions, and this brings them in line so they're consistent and easier to find. jack_the_kobold has 90 posts and tom_the_cat has 96, all mine. Neither target tag exists yet.

I'm only voting no to this because it's possible these names could be taken by someone or something else (franchise) in the future. It's probably very unlikely especially for the jack one, although "tom" and "cat" in character names does pop up now and then obviously because of the string to tomcat. It would be extremely rare but the alias could technically lead to mistagging if someone wants to use tom_the_cat for a different character but they end up not seeing that it gets changed to tom_(nonimousmate) and uploads a post that isn't of your character.

That said, what I have done here now is tag script the change you want for you. All of those posts of both characters are now on the new tag that you proposed for each of them.
