The more I try to think of a decent action scene, the more I realize I've made a mistake.
Zoro is far too strong for the vers. Especially with the advantage I gave him by negating the cursed energy with Haki.
Currently, absolutely no one can beat him except perhaps Kenjaku (and that would only be by attacking him by surprise when his observation haki is not active). And I'm almost certain that by the time the plot gets going, he'll be able to obliterate the entire vers.
I can't think of a serious and coherent action scene that doesn't end with a single slash.
I'm at a dead end. What should I do?
