One Piece is an iconic story that has continuously introduced powerful characters who are strong enough to single-handedly overcome any challenge and emerge victorious. Among these characters, there is Dracule Mihawk, who was introduced early in the series as the strongest swordsman in the world.
Now that the story has reached the Final Saga, fans have still been wondering about Mihawk as the creator has continued to keep this character mysterious. Even though we don't know about his past, there is an undeniable presence across years of storytelling. He has no crew, no kingdom, or even a proper backstory.
Yet everyone in the world of One Piece accepts him as a pillar who would dominate over anyone who challenged him in a sword fight. He has set a benchmark in One Piece, especially around the skills of swordsmanship. Every time a new swordsman enters the narrative, the fanbase instantly measures them against Mihawk.
Fans end up looking at the other characters' swords, and speculating if they would have a black sword, and gauge their techniques. These comparisons help highlight just how overpowered Mihawk truly is. Because, for one, we have next to no information surrounding his character.

Mihawk's situation is unlike that of Shanks, who also barely had any screentime but is now getting a backstory. We know that his life is intertwined with the World Government, Rogers, and Luffy. Mihawk, however, stands on his own. It seems like he has no allegiance to anyone and likes to live by himself.
Additionally, he is a lone wolf, operating from a gothic castle on Kuraigana Island, with nothing but monkeys for neighbors. Yet, no one questions his throne. Eiichiro Oda, ensuring that he is absent for most of the story, has become an anomaly at this point.
Fans understand that the story of One Piece has a lot of lore that is left to be unraveled, but somehow not having any idea about him is terrifying. In a world where strength is often measured by the overall strength of a crew, the power of Devil Fruit, and allies, Mihawk is the exception.
Currently, the only information we have is that he is part of the Cross Guild, but even in this new alliance, Mihawk stands apart. It seems like he does not care about titles or chasing after money and fame. The only thing that gets him remotely interested is partaking in a battle with a worthy opponent.
As we approach the climax of One Piece, all signs point to Mihawk becoming the final gatekeeper for Zoro’s journey. Just as Luffy must surpass the Yonko, Zoro must surpass Mihawk. And when that day comes, it won’t be a war or a chaotic battle in the middle of a larger arc.
Fans of One Piece are obsessed with Black Blade because of Mihawk

It has been noticed in the One Piece community that whenever a new character is introduced in the story who seems to be a swordsman, the first thing fans look for is whether they have a black blade. Because Mihawk’s “Yoru,” the black sword, is not just a weapon, it is a benchmark.
Only a few characters in the world of One Piece are known to have permanently blackened their blades, a process hinted to involve extraordinary Haki control and countless battles. And Mihawk was the first to showcase such a weapon, wielding it with precision and elegance in his early duel against Zoro.
At this point, it has become a ritual for fans to look at even the subtle hints left by Oda. This is a famous practice by fans as they desperately want to know more about the character and simultaneously try to gauge Mihawk's level.
In conclusion, even though he had not taken a significant action that affects the narrative, it is heavily implied that he remains a massive threat. That is the power of myth. Oda barely needs to show him, and yet he continues to dominate conversations.
