Here is everything you need to know about the best mentors to the Straw Hats in One Piece.

Haredas

Haredas is a citizen of Weatheria, one of One Piece’s sky islands, which is where Nami ended up during the time skip. After a rocky start to their relationship, he agreed to tutor her in the weather of the New World, as well as his invention known as Weather Balls.

Both subjects of Nami’s education proved incredibly useful when the Straw Hats reunited and entered the New World. Additionally, her ability to use Weather Balls as weapons has allowed her to greatly contribute to various fights throughout the New World saga.

Hack

Hack is a Fish-Man member of the Revolutionary Army. He is also a master in Fish-Man Karate. During the One Piece time skip, Nico Robin eventually found her way into the care of the oppositional group and grew close with Hack and others as a result.

It was revealed during the Wano arc that he was something of a mentor to Robin during the time skip, teaching her how to use Fish-Man Karate. Considering the skill directly led to her victory over Black Maria, he’s undoubtedly one of the better Straw Hat mentors in the series.

Dracule Mihawk

Dracule Mihawk trained Zoro in swordsmanship and Armament Haki during the One Piece time skip, resulting in the Straw Hat swordsman becoming incredibly strong. The power he wields once the crew reunites is much closer to Mihawk’s level than his old strength, emphasizing just how significant this training was.

While Mihawk’s training doesn’t directly benefit the crew like other mentors’ lessons, his making their first mate stronger does have many indirect benefits. As a result, he’s solidified as one of the best Straw Hat mentors in the series.

Shanks

Serving as Luffy’s initial mentor on how to be a pirate, Shanks is one of two mentors on this list whose teachings took place before the time skip. Much of the Straw Hat captain’s outlook, attitude, and actions on being a pirate are directly influenced by the lessons he learned from the Yonko.

Arguably, Shanks’ role as a mentor to Luffy is still in play, even if only as an ideal or goal to strive towards rather than direct teachings of right or wrong. There’s little doubt he’s one of the best Straw Hat mentors there is in One Piece.

Silvers Rayleigh

One Piece’s Dark King narrowly wins the number one spot for a variety of reasons. One of the most significant reasons is that he served as something of a mentor to the crew at large. He helped them along on their post-time-skip journey and educated them on Raftel.

Additionally, Silvers Rayleigh trains Luffy during the time skip and is directly responsible for the absolute powerhouse he’s become throughout the New World saga. Many of the Straw Hats’ achievements wouldn’t be possible without their captain being as strong as he is, solidifying Rayleigh’s number-one rank here.
