Nova wouldn't side with her, he has no reason to. But it would also make no sense for him to just jump in and splat Cyano if he knows that she's not hostile to him. 

Of course that's my if. It's an If that he could sense Cyanos plans. It's an If that he wouldnt jump into save the ethereal. Though I will say it's unlikely he would save the ethereal, considering the ethereal tried to keep nova from regenerating.

I don't know about Biollante, I haven't seen much of her power. But I assure you. Cyano isn't the only thing to worry about.

Also, love the terminology. I designed Cyano three years ago, and that term was basically what I started with. She has evolved past that and is an interesting character, but that was the base personality I used.
