User blog comment:Roranoa zoro/Defeating Logia users without using Haki/@comment-8823907-20130706101429

Zoro beat monet with haki not speed. But technicaly you are right. Logia userse have to make a conscious effort to be uneffected by objects, blows, etc. so if the user is fast enaugh before the fight he could technicaly catch the user off guard and kill him but i dont think it would work without the element of surprise.
