This article contains spoilers for One Piece's Final Saga.
When it comes to the character of Roronoa Zoro, fans know very well that there are still many mysteries, but the biggest of them all is the one that concerns his left eye. As fans know, Zoro returned from the timeskip with just one eye, and much to the surprise of the fans, nobody ever questioned this. No Straw Hat brought it up, and Oda never addressed it either. However, there is a big reason for this, and Oda has already revealed the truth about it in his manga once.

The D name holds a lot of mystery in One Piece. Its true nature might have just been revealed.
Zoro's Left Eye Is A Big Mystery
- Zoro Lost His Eye At Kuraigana Island
- Oda Has Refused To Answer Questions About Zoro's Left Eye
One Piece fans know very well that when it comes to Oda, changes such as taking someone's eye can never simply be a character design change. It is almost always more than that and for a good reason. While some argue that Zoro only closed his eye because Oda wanted to change his design, the truth couldn't be further away. Oda closed Zoro's eye because it was important, and it is going to be brought up in the Final Saga of the story, which goes without saying.
You look like a blood thirsty demon. — Kaku to Roronoa Zoro in One Piece
As fans know, Zoro lost his left eye at Kuraigana Island, where he trained with Dracule Mihawk, the World's Greatest Swordsman. At some point, something must have happened to him during this fight that compelled Mihawk to take his eye.
If Zoro's left eye was not a big deal, Oda would've already revealed the truth about it, especially when important people press him. When One Piece began serialization, Oda had already told his mentor, Watsuki, that Zoro would go on to close one eye in the future.
In 2021, Watsuki asked Oda again about the mystery behind Zoro's left eye, but Oda refused to answer the question, which confirms that there is a bigger reason for this.
Zoro's Left Eye Holds Demonic Powers
Zoro Has Been Called A Demon On Many Occasions
Zoro's left eye is clearly linked to his inner demon. This shouldn't come as a surprise to any fan. Zoro has been called a demon on many occasions. In Enies Lobby, people could actually see Zoro manifest a demonic aura. Against Kaku, he was labeled a blood thirsty demon. He even manifested a demonic god with six arms during the fight, which fans now know as Asura. Oda canonically calls Asura the demon god.
It's The End Of An Era For The One Piece Anime
The One Piece anime is entering a new era, and major changes are ahead.
Boy, don't tell me, you have the Color of the Supreme King as well? — Kaido to Roronoa Zoro in Wano
Furthermore, whenever Zoro's inner demon is channeled, it is his left eye that glows. Clearly, Oda is making a connection here. What can be assumed safely here is the fact that Zoro's left eye holds demonic power.
Zoro's Eye Will Help Him Beat Mihawk
Undoubtedly, when Zoro fights Mihawk, the left eye that he has closed will help him greatly. Zoro's inner demon will come out eventually, and when he masters this power, he will be stronger than ever before. This eye could make all the difference in the fight against Mihawk, and fans know very well that Zoro will bring it up when they fight.
