The outcome of a hypothetical battle between Roronoa Zoro, one of the main characters in "One Piece," and Dracule Mihawk, one of the most powerful swordsmen in the series, is unknown. The story is still ongoing, and the outcome of potential future battles has not been revealed.

Enma is one of Zoro's swords, which he obtained during the Wano Country arc. Enma is considered a powerful and legendary sword with unique abilities. However, the exact extent of its power and how it matches up against Mihawk or other formidable opponents has yet to be explicitly shown in the series.

Mihawk, known as "Hawk Eyes," is currently regarded as one of the strongest swordsmen in the "One Piece" world and is considered Zoro's ultimate goal to surpass. Mihawk's skills and abilities have been demonstrated throughout the series, making him a formidable opponent for any swordsman.

To determine if Zoro, wielding Enma or any other weapon, can defeat Mihawk, it would require future developments in the story and battles within the "One Piece" narrative. As the series progresses, fans will have to follow the official releases of the manga or anime to discover the outcome of potential conflicts involving Zoro and Mihawk.
