Usopp emerges as a boastful yet cowardly teenager from Syrup Village, son of pirate Yasopp and the late Banchina. His father's departure with Shanks' crew and his mother's childhood death drove him to cope by spinning wild tales of pirate attacks and fantastical adventures, branding him a liar among villagers. He founded the "Usopp Pirates" with three local children and befriended the bedridden heiress Kaya, regaling her with his stories. When the Straw Hat Pirates arrived, Usopp tried deceiving them with false claims of commanding a vast crew. Bonding with Luffy over their link to Yasopp, he uncovered pirate Kuro's plot—posing as Kaya's butler—to assassinate her. Villagers dismissed his warnings due to his reputation, yet Usopp joined the Straw Hats to defend the village. After Kuro's defeat, he disbanded his crew, accepted Luffy's invitation to become their sniper, and departed on Kaya's gifted ship, the Going Merry. Early adventures underscored his cowardice and insecurities, often fleeing danger or inventing excuses to avoid fights. He fought using trickery, specialized slingshot ammunition like explosive pellets and hot sauce rounds—later enhanced with Skypiean Dials. His inventive skills shone in crafting the Clima-Tact for Nami. During the Water 7 Arc, his attachment to the damaged Going Merry sparked a rift with Luffy, prompting his temporary departure. He returned disguised as "Sogeking" to aid Nico Robin’s rescue at Enies Lobby, embodying his struggle for courage. Post-timeskip, Usopp sported longer hair, a goatee, increased muscle, and new attire including a sun hat and headphones. Trained by Heracles on the Boin Archipelago, he adopted "Pop Greens"—seeds that instantly sprout combat plants—replacing conventional ammo. Though gaining confidence and sniping precision, he retained cowardly tendencies against foes like the Four Emperors. In Dressrosa, posing as "Usoland" (falsely claiming descent from hero Noland), Usopp inspired the Tontatta dwarves. His accidental defeat of Sugar—freeing thousands from her toy-transformation curse—earned him the epithet "God Usopp" and awakened his Observation Haki, enabling aura sensing over vast distances. His bounty surged from 30,000,000 Berries (as Sogeking) to 200,000,000 Berries, later reaching 500,000,000 Berries after Wano Country, despite his terror at the increases. Usopp’s core traits blend cowardice clashing with reluctant heroism. He employs psychological warfare, exploiting foes' fears like Perona's entomophobia or Sugar's trauma. Advocating survival over pride, he berated Kin'emon and Kiku for accepting death during Wano’s raid. His dream to become a "brave warrior of the sea" progresses through incremental bravery for his crew—standing against Trebol to shield the Tontatta or enduring Big Mom’s Conqueror’s Haki. Non-canon appearances, like the *Dream Soccer King!* short, featured him in a soccer match against "Villain All-Stars," scoring a penalty shootout goal, showcasing agility and crew compatibility within Luffy’s dream framework. Relationships include admiration for father Yasopp, rivalry-turned-camaraderie with Sanji, and mentoring Chopper. His loyalty to Luffy remains steadfast post-conflict, often supporting weaker crewmates like Nami. The live-action adaptation mirrors his Syrup Village backstory and role in thwarting Kuro.
