I would say (well, as a note, try not to make too many threads on roughly the same topic XD), but I'm going with "Someone we wouldn't know".

The Savior is like (coincedentally) a super "hero". The Savior keeps a realm at peace, but has a villain that will trump them. Then a hero bests the villain. Then another Savior emerges. Repeat.

Emma's kept the peace with everyone anyone mentions, thus her villain has to be someone she'd never beaten. This is likely mainstay villain Rumple or someone new.

Akin to Aladdin who's villain that beats him wouldn't be Jafar. Could just be that the Savior defeats themselves.

Though a solid theory, it's more of a split plot where Regina's fighting her darkness (since Emma did that last season) and Emma's fighting fate (which Regina did in a previous season). Plus, the whole "potential vs Actual darknesss" was a confused storyline and by confused I mean the writers kept mixing them up which is one of the reasons 4b tends to be lower on ranked seasons threads.
