I would honestly be good with either ' An Entirely New Villain' or 'Zachary Varmitech'

Because with Zach getting a hold of only Aviva as a prisoner; it'll be like "The Joker" captureing "Batman" in a way, I mean those two go way back to their childhood years so it would be quite interesting.

As for a possible new baddie who I hope would be another female; I just like the idea of another evil woman taking Paisley Paver's place, now that she turned good pretty much out of nowhere I'd be satisfied if she never came back again.

I'd also wouldn't mind seeing just Koki getting caught by an old or new antagonist but that's a differnt topic all together.
