I mean outside of just being a cool character with a badass design, I’m very interested in what his lore is.
He represents the suffering from success/lonely at the top type and I’m looking forward to seeing how he reached that and how Oda handles it.
Why his origins are still classified as ‘unknown’ in the vivre card?
How his rivalry with Shanks began?
Who are some of the notable swordsmen he defeated on his journey?
How his grudge for the marines began which led to him hunting them?
What was the ‘great betrayal’ that he suffered?
Lots of potential there.
Why his origins are still classified as ‘unknown’ in the vivre card?
It's because he's from the Nerona family, Mihawk is a royal noble,... it remains unknown because Imu is still unknown, once Imu and everything about the Nerona family are revealed, only then will more be known about Mihawk
How his rivalry with Shanks began?
Mihawk was at Roger's execution, which means he heard of him or maybe knew him,... this makes Mihawk interested in the genius of his crew, who is Shanks, even Gaban called Shanks the chosen one,... Mihawk proved that Shanks wasn't the only genius by surpassing his rival in powerful sword ability.
Who are some of the notable swordsmen he defeated on his journey?
They must have been powerful rivals, since Mihawk fought with Shanks, who is very strong
How his grudge for the marines began which led to him hunting them?
When Mihawk gets bored, he usually travels. Most likely, he hunted them when he found them on his travels.
What was the ‘great betrayal’ that he suffered?
It will probably be known when more things about the nobles are revealed.
