Okay maybe we should stop trying to use an indirect word and go for the direct approach.

"Big bad" itself requires no opposite, unlike antagonist. It is also generally confirmed by writers or otherwise extremely obvious. Every season/plot arc has a big bad, with two tops for 2B. The only thing you could argue is whether or not the Queens of Darkness are big bads for 4B, but the writers confirmed that Rumple is 4B's big bad, so.
