Roronoa Zoro's left eye was damaged during his two-year training with Dracule Mihawk on Kuraigana Island.
It got injured during his training with Mihawk. I think it's just an aesthetic change at the end of the day. It doesn't get any mention and after Wano it's pretty safe to say it's not some kind of "holding back until a serious fight" situation.
Zoro's left eye is closed due to an injury he sustained during his training with Mihawk after the time skip. He lost his eye while training with Mihawk, likely due to a blade accident during practice. The scar on his face suggests a vertical cut, potentially from a sword or knife.
During the two-year timeskip after the events of Marineford, Zoro traveled to Kuraigana Island to train with Dracule Mihawk, the world's strongest swordsman. When he did come back, he left fans stunned with his new scar and a now permanently closed left eye.
ð¿ As a child, Zoro could never defeat Kuina. It's known that he didn't lose just once or twice—he lost **2,001 times**, even in battles with real swords. ☠️ After Kuina's death, Zoro swore to become the strongest swordsman, a name that would be known even in heaven.
Actually not just 1, he can eat 3 devil fruits. Yes. Boom!
And against Page One he overwhelmed him with his speed and stealth, but he did almost no visible damage. He has had other fights, but these are his strongest opponents so far. ZORO -Zoro in base form is stronger and has more stamina and durability than Sanji though only if Sanji doesn't use the Raid Suit.
Zoro's Eye | Fandom. Let us for a moment consider that Zoro can actually still see out his left eye and also drop all the theories about him having Hawkeye's eye or the even more ridiculous ones about him having the sharingan.
Shu and the rust rust fruit are 100% canon. He grabbed Zoro's sword on the bridge of hesitation, rusted it to dust, and Zoro buried the sword on Thriller Bark alongside Brook's crew.
So the longer you train with one eye, the stronger you theoretically become when you open it. When the time comes where Zoro knows he can't win, he will open his left eye to give himself a significant boost of observation haki or senses that will essentially boost his current strength by double.
In episode 575 at the time 7:40 you can see Zoro in a clear view of his scar on his left eye and that eye is open and so far every time I search about it I always get the same answer - Zoro has never opened his left eye after the time skip and Oda never explained why.
Though Mihawk easily won their first encounter, he grew to respect Zoro, and agreed to mentor him in further swordsmanship during the timeskip.
His dream is to become the greatest swordsman in the world, to honor a promise he made to his deceased childhood friend and distant cousin, Kuina.
Their father modified them while their mother was still pregnant in order to endow them with superhuman abilities. However, due to Sora's own attempt at ensuring her sons would keep their emotions using a counter-drug, Sanji's genetic modifications were repressed, and he was born a normal human.
So, his current power level surpassed his power level in Wano arc. If the Straw Hats are to fight Shanks and another opponent stronger than Shanks, then Luffy will defeat the stronger opponent and Zoro can defeat Shanks despite Shanks being stronger.
Usopp demanded respect and the ship, so Luffy gave him respect via a proper fight. Sanji was hiding his true feelings so he could silently sever all his ties and sacrifice himself so no one gets hurt. Thus Luffy gave Sanji the chance to see that Luffy will stop at nothing to save his friends.
After the Timeskip. During his two-year training period with Mihawk, Zoro learned to imbue his sword with Armament Haki, drastically increasing the power behind his sword attacks, including Nine Sword Style.
Blackbeard and Loki are the only characters confirmed to wield two Devil Fruits; however, they use them in completely different ways—Loki seeks peace, while Blackbeard aims to conquer the world. . .
Hair color in anime and manga is often used to reflect a character's personality or powers. For Zoro, green can symbolize his vitality and energy, traits that are essential for the pirate hunter turned legendary swordsman.
Zoro gave Luffy a promise that he would become the best swordsman in the world and protect Luffy until the end. This promise is proof of Zoro's commitment and loyalty to Luffy. He views his promise as an honor and would never betray Luffy.
While Ace's death is undeniably sad and avoidable, it ultimately benefited the series and solidified its ability to kill off characters and create dramatic tension. Of all the deaths in One Piece, Ace's is the one that's often regarded as both the saddest and the most infuriating.
He only showed up at Marineford because his status as a Warlord obligated him to. He fought only as much as duty required. Fighting Shanks would've been reckless, risking unnecessary casualties and potentially reigniting a pointless battle.
