Usopp/Misc.

Anime and Manga Differences
In the anime, when the Pacifista was locking onto to Usopp for its next attack, its bounty detector labeled him as Sogeking, even though he was not wearing his Sogeking mask. Though his nose or the Kabuto could've given him away.

Trivia

 * According to Mr. 2, Usopp has the funniest nose in the world.
 * It is possible that Usopp's long nose was inspired by the fairy tale "Pinocchio", as Pinocchio was a wooden puppet whose nose grew longer whenever he told a lie.
 * In addition to the Straw Hats' Jolly Roger, Usopp also has one of his own, like all the other members of the crew. The flag was first seen when Luffy asked him to design and paint a Jolly Roger for the crew. Though it was supposed to reflect everyone, Usopp designed his own Jolly Roger as their symbol, reflecting his delusions of captainship. It has Usopp's nose, bandanna, a star, and a slingshot for a cross-bone. Usopp's design was immediately rejected.
 * Usopp is described as being like the third son of a family.
 * Ironically, most of the tall tales he told Kaya have came true at some point during the Straw Hats' voyage. These include meeting a Giant Goldfish (as the crew was leaving Little Garden) and fighting against a giant mole (against Miss Merry Christmas during the climax in the Arabasta arc).
 * In the 4th Japanese Fan Poll, Usopp was voted the eleventh most popular character in One Piece.
 * Usopp's favorite food is pike from an autumn islands as well as other fish of the season. He hates mushrooms because when he was young he ate a poison mushroom.
 * Usopp's_shadow.jpg can be seen in the corner of Luffy's wanted poster and Zoro's wanted poster. In Luffy's he is simply viewed from behind. In Zoro's his silhouette is faintly seen through the smoke in the background of the poster doing a Crocodile impersonation. However, in the anime, the latter was cut out of Zoro's poster most likely due to the fact that it's not easily visible and was thus overlooked. It was later corrected in Episode 152 but omitted again in the second bounty poster.
 * Kappei Yamaguchi, Usopp's Japanese VA, came up with the notes to the Sogeking song. Oda-sensei provided the words and then asked him to develop the notes himself. Kappei also stated that the Sogeking song is the most requested song for him.
 * He is the one who introduced the rubberband to the Skypieans.
 * Usopp would be African in the real world.
 * Sonny Strait, the FUNimation VA for Usopp, has stated several times during the Funimation DVD commentaries, that Kappei Yamaguchi is his favorite Japanese voice actor, saying that whenever he listens to Kappei's performance in recording it's like he's saying "Top that American voice actor!".
 * "Hercules" and "Kabuto" are both types of beetles and incidentally represented by both Heracles and Usopp respectively (in Usopp's case it is his weapon).
 * Usopp's name is likely inspired by the great story writer Aesop, whose most famous book is titled "Aesop's Fables." This would make sense in that Usopp is notorious for telling "fables" (lies or exaggerated tales) all the time. It could also come from the Japanese word uso, meaning lie or lies.
 * Usopp's personality could also come from The Adventures of Baron of Münchausen, who said he had traveled around the globe on a cannonball, a lie Usopp himself said in episode 19, though no one gave him any attention.
 * In an SBS, when asked which flower Usopp resembles the most, Robin's Voice Actress replied he most resembles a daisy.
 * He and Sanji both claim to have never been sick, and thus do not know what it feels like.
