To escalate
Z0a was being cornered. However, this doesn't mean that she is at her end yet. It's just that she had a much harder time dealing against the seven people than back then when having to deal with the Queen who only had subordinates that didn't counter her special ghostly abilities.
These seven, or rather, the six masters, they all had their own means to hinder her from ever thinking of a way to attack. It was impossible for Z0a to make a move, and in fact, she might have already been on the losing side if the seventh opponent of hers was not the plant guy but the one master who was remaining neutral.
Fortunately, Z0a wasn't alone. Of course, not being alone had brought some trouble for her as well since she had to be watch out for those that were by her side. This trouble wasn't too big however, because those around and with her, they were quick to adapt to the situation, and had abilities to counter against those of the enemies in order to be of assistance of Z0a.
