Trivia

 In one of the SBS sections of One Piece, in reference to Shanks and Buggy's 'which is colder' question, a fan asked Oda who got it right. He went on to explain that the Arctic was just a mass of ice and the Antarctic was a continent, which was made of land. Since land is colder than the sea (and the Arctic is frozen sea whereas the Antarctic is frozen land), Shanks was correct and the South Pole is colder.[39]

   Voice actor Shūichi Ikeda is best-known for having voiced "Red Comet" Char Aznable in the original Mobile Suit Gundam anime, where the aforementioned character was known for only piloting red mechas.

    Even though he has traveled the world, Shanks believes the best sake can be found in his hometown in the West Blue. He also refers to alcohol when with Whitebeard as "healing water".

    Shanks is one of the many characters in One Piece with a unique laugh, starting it with a "Da" (i.e. Dahahahahaha!).

    Shanks' nickname for Luffy as a child ("anchor") is partly ironic as a "Shank" is part of a ship's anchor.

    Shanks starred in the Mugiwara Theatre - Red-Hair of Class 3 - Sea Time written and drawn by Oda. The strip was done after he claimed first place in a poll for characters fans wanted to see appear in the Mugiwara Theatre series.[40]

    During the JUMP Festa 2008, Shanks' voice actor was absent for the One Piece stage show where all the One Piece voice actors put on a act together. During this, the Mugiwara High School was acted out. In Shūichi Ikeda's place, Oda himself went on stage with a chalkboard while wearing a hot pink wig and introduced himself as "Shanks".[41]

    Shanks shares the same birthday as Franky (March 9).

    In the 4th Japanese Fan Poll, Shanks is ranked the 8th most popular character in One Piece making him the most popular of the Red Hair Pirates and the Yonko.

    When Shanks first lost his arm, part of his arm can still be seen remaining, however later he is seen with everything from the shoulder joint onwards missing completely. However, a doctor may cut off the remaining flesh of a patient who has lost a limb at the nearest joint to create a new cleaner cut. This is done to avoid some serious medical issues that can kill a patient.
    Shanks appears to have favored his left arm before he lost it, as he is always seen holding his sword in his left hand during flashbacks.

    The only duel actually seen between Shanks and Mihawk is in the game One Piece Unlimited Cruise 2. It was used as an intro for both of them as bosses.

    In the anime when Ace meets Shanks, he is seen with both arms. This was an animation error.
