Nice crossover. Personally I think Erza would beat Zoro but that's just me. She's mastered a multitude of weapons while Zoro has only mastered a few. Of course, both of their weapons could break but Erza could simply summon more ones while Zoro could not.
Yeah. That's why I made a Death Battle where the two of them fought. Erza ended up winning. I thought the one ScrewAttack made sucked since Erza was OOC for one...but if you want you can read mine...
