Usopp/Personality and Relationships

Personality
Usopp is one of the more sentimental Straw Hat Pirates, and cries or loses his temper in moments of emotional stress. At the start of the series, Usopp was an easily frightened, anxious, insecure, compulsive liar. Unlike Nami (whose cowardice is linked to just wanting to stay alive), Usopp's cowardice was the result of his fear and insecurity, especially when faced with uncertainty. Usopp is able to put aside his fear during more desperate times: despite being afraid, he faces those fears for the sake of his friends and people he barely knows. Most of his lying was intended to make him feel better as Usopp is easily overwhelmed by his opponents, such as Aokiji, and used to run from them. Though some of Usopp's lies actually help and inspire people like Chopper and the dwarves of Dressrosa   He used to be the first to come up with an excuse to avoid doing something or to avoid putting himself in danger. One of the most frequently used excuses is that he gets a disease named, for example, "Can't-get-on-this-island disease". Before the timeskip, he also had delusions of acting like the captain, referring to himself as "Captain Usopp" when talking to Chopper, opponents, or strangers.

It is this which leads to his feud with Luffy - specifically his refusal to part with the ship he had come to love. This was the result of all his insecurities about his usefulness as a member of the crew culminating within him and finally exploding under the stress of having just been badly beaten by the Franky Family and then losing his ship. He was worried that since he was not as physically strong as Luffy, Sanji, and Zoro, he was just a burden to their crew. Though he is very intelligent and a talented sniper, he had trouble seeing his better qualities and his strengths until the fight at Enies Lobby opened his eyes. After said fight, Usopp was able to finally see his better half and realized that even though he was not as strong as the others, he was still quite powerful in his own right.

After meeting the giants Dorry and Brogy in the Little Garden Arc, Usopp began to want to travel to Elbaf one day and meet the proud warriors there. Usopp gave his first glimpse of understanding the ways of the warrior and the pride of a duel during the giants' battle. As a result Usopp often sees the Elbaf warriors he has met in his travels as sources of inspiration in his journey to become "a brave warrior of the sea".

Throughout Thriller Bark, many members of the crew fell victim to the effects of Perona's negative powers, causing them to become incredibly depressed to the point where they could not move. However Usopp, though slightly affected by the power, got to his feet claiming he could not become negative, because he already is negative, even saying it in a brag-like way. Perona claimed he was the only person who was ever immune to her powers; to the point using her powers on him causes her to become severely depressed, so she fled from him in fear. After finding out about Ace's death, he developed the courage to escape and help out Luffy through the hardship or else he will not call himself a crewmate. Usopp shows an unusual lack of fear in his attempts to get off the island to rejoin Luffy, showing no hesitation in facing the giant beetle who was bigger than he was.

He also has a dislike for mushrooms, due to eating a poisonous one when he was younger.

One, two, on the third step you will get shot by me and that'll be it!... Oh man, I'm losing my edge. I used to bluff better in the past, but now I can actually do these things!

After the timeskip Usopp becomes more confident in himself, especially in terms of his fighting abilities, and boasts that he has become a warrior. Prior to the timeskip Usopp freaks out about joining his crew in the fight at the Human Auction House. However, on his return to the Sabaody Archipelago, he shows no fear of the Impostor Straw Hat Pirates despite them having guns and attacks them without hesitation, and then turns his back to them to talk peacefully with Nami. Later in the battle of Gyoncorde Plaza, when facing off against Daruma, an officer of the New Fishman Pirates, he is shown to be smiling, seemingly excited about his imminent fight, though at the time, he was under the impression that Chopper would be providing him with backup. He now comically smacks people (mostly Luffy) more frequently when they annoy him or say something stupid. However, now he is willing to stand and fight with the rest of the crew. He is still reasonably frightened of danger that is beyond his ability though, such as Luffy and Zoro popping the coating bubble while deep under the sea or the White Strom or when traveling on Green Bit he was adamant that he and Robin stay close together. His "I-can't-go-on-this-island-or-I'll-die-disease" is still the same as shown when he did not want to go to Punk Hazard, even despite the fact he understood the strength of his crew members. His habit of lying also remains, as displayed on Green Bit, where he adapted quickly to the naive dwarves, and immediately proclaimed himself to be Usoland, descendant of the hero Noland, after discovering the connection between the two.

Usopp has also, on a few occasions displayed a subtle perverted side of him, that is often not noted upon. The best example of this is when he, Zoro, and Brook are trapped in a suspended cage in Ryugu Palace and Brook explains his newfound ability to extend his soul over long distances. He also explains that his soul can travel through solid objects, including walls, to which he begins to have a small nosebleed, indicating that he used this ability to peep on girls over the duration of the timeskip. Usopp begins crying to Zoro, stating that Brook was, "making him jealous."

He seems to have become more prideful in himself after Dressrosa, after he was ecstatic that he received a 200,000,000 bounty, when before, he would be terrified of any bounty he received.

Alter-Ego (Sogeking)
I've heard the entire situation from him. It seems as though you wish to save a young lady. I need no cause to lend my aid to you. Let us fight together! Sogeking is Usopp's alter-ego developed during the Water 7 and Enies Lobby Arcs, when he left the crew. Later, seeing the others trying to save Robin made him feel guilty for leaving, so he stated to Sanji and Franky that he cannot help them fight for this reason. He hastily disguised himself in a mask and cape and began calling himself "Sogeking". This name is a pun between "sogeki" ("sniper" in Japanese) and the English word "king." He is called "Soge King" in the FUNimation subs. In the Viz manga and FUNimation dub, he is called "Sniper King". Sogeking's trademark mask is from the Sea Train Puffing Tom: as Sanji leaves the last car of the Sea Train, the mask is visible sitting in an open suitcase. It was probably left over from the mask festival that was taking place on a nearby island at the time. The Sogeking costume is only complete when Usopp incorporates his favorite goggles into the mask's eye holes.

During this facade, he sometimes dons a deeper voice to disguise himself, which can be seen as the "true" Sogeking. Sogeking refers to nearly everyone with a "kun" suffix (Luffy-kun, Zoro-kun, Robin-kun, etc.) and, when asked for the whereabouts of the 'Island of Snipers' he supposedly comes from, maintains that it exists "in your heart." As Sogeking, he changes the name of his attacks from Japanese to English, such as the "Firebird Star" when shooting at the World Government flag. The "true" Sogeking has been known to break character on occasion, speaking in Usopp's normal voice and temporarily dropping his fearless demeanor. For example, he briefly lost his cool when Nami called him "Sogepp." Everyone except for Luffy and Chopper realized right away that Sogeking was Usopp at the sight of Usopp's significantly long nose. Chopper was even fooled to such an extent that he accepted an autograph from Sogeking thinking him to be a celebrity, and now keeps it hanging up in the sick bay of the Thousand Sunny as a gift from Usopp once he learned the truth. Tamanegi, Ninjin, Piiman and Kaya were also able to recognize him, though they claimed no one else in Syrup Village did.

As his alter-ego, Usopp was able to fight alongside the others without having to address the issue of his departure. During his time spent as Sogeking, Usopp began to realize that while he was one of the weaker crew members, his role as the crew's sniper and a supporting crew member made him more valuable than he thought. Ultimately, he was recorded as Sogeking on his wanted poster. The fact that Usopp himself is not technically wanted by the law later allows him to slip through enemy lines seemingly undetected, as shown when Oars originally let Usopp go because (being Luffy's shadow) Oars did not recognize him as Sogeking.

Sogeking: Calm down! Fight, Usopp-kun! Usopp: Shut up! I'm done for. There's no way I can win this! Sogeking: That's not true! You can do it! Usopp: Do you have any basis for that? Sogeking: None! Usopp: You don't!!?

During his fight with Perona, Usopp started arguing inside his head with his alter ego over their situation. Once he put on the mask, he gained the confidence that enabled him to defeat Kumashi. This indicates that he compartmentalizes this aspect of himself to deal with the stress of the situation.

The genuine Sogeking has not yet made an appearance since the two year time skip. However, during the Straw Hats' return to Sabaody Archipelago, when Usopp and Nami face four of the Impostor Straw Hat Pirates, Usopp sees the mask worn by the Fake Sogeking. While he says "Sogeking", it does not indicate whether he is merely surprised that someone is impersonating him or actually believes it is the real Sogeking. Although when he reunites with Chopper, Usopp and Nami tell Chopper that they are impostors.

Crew
Usopp does get along with his crew. However, as the comic relief character, he is often made fun of. When he left the crew, he said that he felt inferior to the rest of the crew because of their courage and superhuman strength.

Upon Usopp's introduction, the crew only consisted of Luffy, Zoro, and Nami. When they arrived to his village, he immediately attempted to scare them off with his typical lies about his large following, but Luffy instead found him very amusing. He told them about Kaya and the ship that her family owned, and the Straw Hats decided to try her as an option. They instead arrived to witness Usopp defending his pirate heritage to Kaya's servant; this prompts Luffy to remember Usopp's father, Yasopp, and the many stories he told Luffy about him when he was a child. This immediately creates a bond between Luffy and Usopp. Usopp fully befriends the crew when they decide to help him defend his village from the Black Cat Pirates. He thinks they don't take him seriously because he shows obvious fear by his legs shaking as he talks, but Usopp is touched when they reveal that they are helping him because they admire his courage and determination.

Despite his own fears and shortcomings, Usopp continues to draw strength from this faith in him as the crew grows larger, and decides that he will always do his utmost to help the crew. He eventually passes this philosophy on to Nami and Chopper as well, who also don't possess the monstrous physical strength that the "Monster Trio" does. However, while Nami and Chopper aren't as strong, their roles as navigator and doctor respectively are still absolutely essential to the crew. After facing an opponent as powerful as Admiral Aokiji during the Long Ring Long Land Arc and not being able to do much, the seeds of doubt as to his usefulness to the crew are planted. They grow larger after he loses a large sum of money for the crew after being abducted and beaten by the Franky Family, and come to a head when Luffy decides that the crew must say goodbye to the Going Merry at Water 7. Although Usopp leaves the crew, he never loses his attachment to the ideal that he must still do what he can for them, which prompts him to go as far as to create an alter-ego (Sogeking) to still help them rescue Nico Robin. Most of the crew still recognizes him however, and even though they didn't agree with his decision to leave, still grant him support, advice, and trust.

Although it doesn't come easy, his re-entry to the crew shows that the love is still mutually unconditional. Usopp has grown exceptionally from this experience and now trusts Luffy and the crew implicitly; dedicating his time-skip training to becoming stronger for his captain's sake.

Luffy
He was inspired by Luffy, Zoro and Nami and decided to go out to sea, following his dream of becoming a "brave warrior of the sea". He will often goof off with Luffy and shares a strong, brotherly relationship with him. He and Luffy share a common path towards an eventual meeting with the Red Haired Pirate Crew: Luffy to reunite with Shanks and Usopp with his father. Through this small connection and the fact that they are the same age and, thus, at the same level of maturity, Luffy and Usopp had a very special bond from the moment they met. Usopp fully believes Luffy will become the King of the Pirates and got furious when Miss Merry Christmas laughed at his dream, but even with this faith in Luffy it took a long time for Usopp to truly respect Luffy as Captain. Usopp had difficulty going along with all of Luffy's decisions, the breaking point came over the fate of the broken Merry, Usopp couldn't stand the idea of throwing the ship he loved aside and fought with Luffy over it. Naturally Luffy won (but took a lot of damage from Usopp) Luffy gave Usopp the Merry and left with the rest of the crew, both Luffy and Usopp cried over the turn of events. Usopp was depressed and felt he could't faced Luffy again but when Robin was taken by CP9 Usopp disguised himself as "Sogeking" who awed Luffy and Chopper (as they didn't know it was him). Usopp was one inspired Luffy to get up and beat Rob Lucci revealing himself in midst of a battle and even challenged Lucci to fight. but miraculously Luffy got up and beat the assassin before he could kill Ussop. After the battle at Enies Lobby, Luffy was more than willingly to let Usopp back into the crew but Zoro put his foot down saying Usopp had still disrespected Luffy as captain and he would only accept Usopp back if he apologised. When the crew were leaving Water 7 Ussop thought they accept him back with open arms, but he saw them leave without him the Sniper broke down in tears and yelled his apology, Luffy (likewise crying) stretched himself to Usopp and told him "grab on you idiot" with Usopp part of the crew again Luffy and the others were jubilant to have the cowardly Sniper back. When Usopp heard that Ace had died and that they would meet again in two years, Usopp swore he'd become stronger for his captain and trained relentlessly with Heracles for two years straight. After the time skip Usopp was happy to see his Captain again.

Chopper
Chopper loves Usopp's stories and often falls for his tall tales, and Usopp in turn loves Chopper's hero worship of him and makes a point to act cool in front of his "younger brother". Chopper was very upset when Usopp left the crew and were elated when he begged to rejoin. Chopper was in awe of "Sogeking" and asked for his autograph.The other crewmates often request that Chopper make cure for Usopp cowardliness to which Chopper says it's hopeless cause. Usopp and Chopper (and sometimes Nami) are easily terrified running like the wind when monsters and strong foes appear and the pair will often cower behind stronger crewmates. Despite this cowardly nature the Sniper and doctor make a surprisingly good fighting team, seen when they defeated Mr 4 and Miss Merry Christmas and after the time skip when they bested the New Fishman Pirates.

Nami
He gets along with Nami but, like Chopper, is often intimidated by her sometimes violent behavior. Usopp and Nami have a special bond as they are the only "normal" crew members. At some point during the Alabasta arc, Nami approached Usopp and asked him to make a weapon for her, convincing him to do so by confessing her feelings of inadequacy when compared to the awesome strength of Luffy, Zoro, Sanji, and even Chopper. Nami said that Usopp was the only one who could understand these feelings, and thus was the only one who could help her. Usopp and Nami are usually the ones to prevent Luffy making the crew go on super dangerous adventures but they are rarely successful and will sulk afterwards. Usopp cares for Nami and did his best to stop foes like Absalom and Shiki from getting their hands on her. Like Sanji Usopp does find Nami attractive and does make noticed of her body a few times, like in Thriller Bark when he saw her naked he bowed and said "thank you" much to Chopper's shock and upon them reuniting after 2 years apart while Nami hugged him, complimenting on how he has grown, Usopp noticed she grown too as she obliviously hugged his face to her breasts.

Zoro
Zoro gets along well with him, but before the timeskip, often admonished Usopp for his cowardice and sentimentality. Zoro displayed unusual caring or loyalty for Usopp by attempting to slash Nami when she lied that she had killed Usopp during the Arlong Arc before being stopped by the recently joined Sanji. Zoro has also been similar to an older brother for Usopp, demanding to the others that they must let him step up and deal with the consequences of leaving the crew, attempting to help him become a "Brave Warrior of the Sea" on his own. Usopp will often cling onto to Zoro's legs leading to Swordsmen shaking him off. Zoro while showed no outwards signs of grief he was nerveless concerned when Usopp left the crew and was happy to fight with him when he was disguised as "sogeking" even when they got handcuffed together. Though he was pleased Usopp was safe Zoro still prevented Luffy from letting him rejoin the crew as Zoro wouldn't let anybody (even friends) disrespect his Captain When the stubborn Sniper finally gave in and apologised Zoro was happy to have him back. After the time skip Zoro and Usopp get on well, Usopp was able to beat him up at one point in Fishman Island when the Swordsmen was going to pop the bubble shieding the ship wile submersed (though it was more of a comical moment than actually fight) later in Dressrosa Usopp like Bartolomeo was awed when Zoro defeated the stone giant Pica, Usopp will still cower behind Zoro as seen recently in Zou when facing the Minks Usopp hid behind Zoro but still verbally threatened them and even used Zoro's arm to point at them.

Sanji
Usopp did not get on well with Sanji at first, when they met Usopp was annoyed that Sanji was giving Nami free food while Usopp had to pay for mushrooms that he hates to which Sanji asked why he asked for them in the first place but Nami broke up the argument. When they met again Sanji accidentally knocked Usopp out, when Usopp came around Sanji tried to make it up by calling him "buddy but to no avail. After Arlong Park  the Cook and Sniper got on well enough. both Sanji and Usopp deeply enjoined Whiskey Peak and slept though the midnight battle. Usopp soon became to awe Sanji's strength and battle prowess and would request that Sanji be his personal bodyguard but the Cook will shrugged him off (only wanting be Nami's bodyguard). Sanji will often act like he cares little for Usopp, but this is far from true as Sanji has saved Usopp life countless times like when Enel fired his "God's judgement"  lighting attack at Usopp Sanji kicked him out of the way and took the blast himself, and in Tower of Justice when Jabra was about to kill Usopp Sanji return in the nick of time to kick him away and then fight him. Sanji even kicked Luffy when he about to tell Usopp to leave the crew and was one the most upset when Usopp did leave and  chased  after him along with Nami and Chopper. Sanji was the one to ultimately inspire Usopp to see the value inside himself saying that while he (Sanji) was physically stronger and could do what Usopp couldn't do, Sanji also stated that only Usopp possessed skill to save Robin and could do what he couldn't do. Usopp and Sanji make quite the comic pair as seen in Skypeia and Strong World as Sanji will fearlessly charge in battle while dragging a terrified Usopp behind him.

Robin, Franky, and Brook

Usopp was scared of Robin, as well as Brook when they first appeared to the Straw Hats; however, he changed his views over time and sees them as good friends, as seen when he wanted to stay close to Robin on their journey in Green Bit.

As for Franky, while he did beat up Usopp during the Water 7 arc, they began to understand each other once they talked about the Going Merry. Franky also told Usopp that he liked him and asked him to join him as a ship dismantler, but Usopp declined because he would rather stay as a pirate. Usopp is usually the one who tests Franky's cannon-type inventions. They have also bonded over their ability and mutual fondness for engineering. They both tend to the ship together, upgrading and maintaining it. After the Dressrosa Arc, Franky has gotten a small grudge on Usopp, because now his bounty is higher than his own, but they are still friends.

Kaya
He shared a deep fondness for Kaya back in his village due to her losing her parents and often tried to keep her happy. Unfortunately, his lies backfired when he tried to protect her when Kuro put his 3 year plan into action and Kaya lost all respect for him, until the truth has been revealed. After Kuro's plan is stopped, she decided to try to remain happy for him while he was gone and Usopp is left happy that she is safe. When his "Sogeking" bounty is made public, Kaya is able to identify him and seemed proud of his accomplishment. Just seeing his poster inspired her to get back to her medical studies, wanting to be able to take care of his injuries upon his eventual return. Kaya is in debt with her friend Usopp and has grown very fond of him since he saved her life, more so than she ever had been in the past. She was willing to listen to Usopp's tales knowing he was a liar, yet incapable of accepting some of the grim realities when the stories become serious about Klahadore, believing the butler to be loyal and faithful to her.

Partially due to Kaya's influence, Usopp found it virtually impossible to part with the Going Merry, having a strong bond with the ship. Usopp refused to relinquish the ship despite the rest of the crew already gave up on it due to it being irreparable and dying, to the point of nearly breaking his ties with the Straw Hats solely to keep the Merry for himself. Usopp has knowingly deluded himself that the Merry can be saved, until he was made to see the undeniable fact, that by forcing the Merry to go on would just cause it pain. When the Merry was finally given a Viking's funeral, Usopp cried deeply.

Usopp Pirates
Back at the village, his old pirate trio also await his return. Originally they were a small crew who would create minor mischief together for fun, they instantly believed him when he had claimed the butler Klahadore is a pirate. Usopp lied to them by claiming that he lied to get back at Klahadore, in order to keep them safe; although they act disgusted at first for their captain's supposed cruel jokes, they remained skeptical and knew deep down Usopp was simply hiding the truth from them. They unhesitatingly went down to the battlefield to attack Kuro, and protected Kaya with their lives under Usopp's request.

When they last met they parted ways with him to lead off on their own dreams. They have been following the reports of him ever since via the newspapers and are proud to have called him captain. The former members of Usopp Pirates (Ninjin, Tamanegi, and Piman) were seen again after Enies Lobby was raided, reacting to Usopp's new bounty. Even though it said "Sogeking" and he was wearing a mask, they could recognize him because of his nose. Two years have passed and they were recently seen reading news of the Straw Hats' return in the newspaper that shows the current look of their former leader, Usopp.

Dorry and Brogy
When Usopp first met them, they heavily inspired Usopp's dream to seek out the land of Elbaf and train with Giants to become a great warrior of the sea. Usopp looked up at them like heroes and found their personal duels to be very moving. When their duel was interrupted it heavily enraged Usopp, and sought out the perpetrator. When fighting to protect the Giants, it was one of the few moments Usopp showed absolute bravery and confidence against a superior opponent. The two giants befriended Usopp and helped him and the Straw Hats leave the island. Even when the Merry was swallowed by a giant goldfish, Usopp's belief in them did not waver that they would keep their word and let nothing stand in their way.

Oimo and Kashi
"Sogeking" also made friends with the giants Oimo and Kashi after he revealed the truth to them concerning the Usopp (still disguised as Sogeking), who had been accidentally left behind, hears them lament about their tragic existence. After this he realizes their leaders were none other than Dorry and Brogy, whom the Straw Hats had met during their adventures in Little Garden. He told the two the real truth and how he had met them and proved this by showing Dorry and Brogy's unique laughs and combat style. Angered at being deceived for fifty years, Oimo and Kashi switched sides and swore vengeance upon the World Government and Naval forces that had kept them in the dark for so long. They arrived just in time to save the Franky Family from being overwhelmed by the marines when Yokozuna gets knocked out, as well as take over it in guarding the door to the inner courthouse, keeping the marines out — But not before flinging Sogeking up to the rooftop to rejoin the Straw Hats.

Heracles
After landing on the Boin Archipelago, Usopp was rescued by, and quickly befriended Heracles, who tried to stop Usopp from injuring himself any more than he already had while he tried to escape Greenstone. Heracles also saved Usopp from being eaten by the Stomach Baron when Usopp became fat. He later became Usopp´s sensei and helped train him in the 2 years the Straw Hats were separated to become "the true king of snipers".

Tontatta Kingdom
Due to Usopp's lies with the Dwarves of the Tontatta Kingdom about him being a descendant of Montblanc Noland, the Dwarves view him as their hero. Leo in particular worships Usopp and values him as a hero. Due to his lies, Usopp was refered to as "Usoland". However, Usopp was terrified of the thought of fighting against a Shichibukai as powerful as Doflamingo and intended to leave when he got the chance. When he did try to abandon them against Trebol, Usopp, hearing Leo and the others refusing to doubt Usopp, caused the Pirate to be filled with guilt in his actions and ultimately return to face the stronger Donquixote Family members to save the Dwarves and become their hero. Though he was easily defeated by Trebol and Sugar, he was able to make Sugar pass out due to the Tobasco ball shoved in his mouth which made him make a terrifying image and ending her Hobi Hobi no mi powers in Dressrosa. Because of his actions, the Dwarves weaped over his success with Leo promising they'll make a statue in honor of his heroism. Even with the truth about who Usopp is, none of the Dwarves turned on him and protected him during Doflamingo's "Bird Cage" game.

Hajrudin
Due to Usopp's actions in saving the toy slaves, the Giant Hajrudin came to greatly respect Usopp for his courage. Having been saved by Usopp from the Hobi Hobi curse, Hajrudin immediately grew to admire Usopp to the point where he held Usopp in the air before all the other slaves to proclaim him as their savior.

Abdullah and Jeet
Because Usopp save them from the Hobi Hobi curse, the two criminals came to respect him for his selfless deed. In fact, when Usopp was held in the air by Hajrudin and declared as their savior the two had shed tears of joy and happily followed his order of saving the dwarves and destroying the SMILE Factory. Unlike the other former toys who pursued the bounties of Doflamingo's enemies the two stayed on their "God's" side and wanted to take Doflamingo's head as repayment. Additionally, Abdullah even called those that pursued the bounties of the Donquixote Pirates enemies "shameless" for their lack of gratitude to the ones who saved them from slavery.

Kuro
He has a deep personal grudge for Kuro, whom he fought against to protect Kaya. He mocked Usopp when he called himself a pirate, calling his act a "childish game", and sees him as equal to an insect. Usopp dislikes him for this, and comes to hate him after realizing his true intentions and plans for Kaya. Upon discovering Kuro's true identity, Usopp came to fear him for his reputation, and even regretted punching him, a fear that only intensified when he saw Kuro's superhuman speed. However, when Kuro openly insulted Kaya, breaking her heart in the process, Usopp forgot his fear and flew into a rage, attempting to strike Kuro once again.

Perona
Due to Usopp being the first (and only) person immune to Perona's negative powers, he made an enemy of the Ghost Princess Perona. While he had difficulty in defeating her due to her toy zombies, Usopp was able to defeat her after making her believe she was going to be crushed by a 10-ton hammer which was really just a balloon. Because of her defeat, she harbors a grudge against Usopp for losing her first fight. She even stated that "the long-nose" is her natural enemy when addressing Nami.

Marines
While he himself is at ease with the Marines, his plainly obvious alter-ego carries a bounty. In the anime, the Pacifista was able to associate Usopp with Sogeking, with Sentomaru commenting that his epithet, "King of Snipers" (Sogeki no Ō-sama), was ridiculous. In the New World the Straw Hat Pirates had new pictures taken, with an image of Usopp titled "Sogeking". It is likely that he is as recognized as any crew member, minus Sanji, despite his name differing on the wanted poster.

However in the wake of Donquixote Doflamingo and the Donquixote Pirates defeat at the hands of the Straw Hat Pirates and Heart Pirates Alliance, the Marines have issued new bounties for the entire Straw Hat crew, resulting in Usopp's wanted poster being upgraded with his true name and face (albeit an unflattering photo of Usopp while he was unconscious), while his bounty was increased to 200,000,000 along with his new epithet, God for his role in knocking out Sugar and freeing all the Toy slaves which ultimately led to Doflamingo's years of deception being exposed. This has apparently caused the Marines to view Usopp as a far greater threat than they did in the past as his current bounty is the third highest among the Straw Hats.

Trebol
Usopp was very afraid of Trebol after he saw the Donquixote executive set several dwarves on fire, causing him to run away. However, he overcame his fear after he realized the dwarves' dependence on him, and attacked Trebol. He was easily defeated by Trebol, but did not regret his choice.

Sugar
Due to frightening her so much that she passed out, which in turn undid the effects of the Hobi Hobi no Mi on hundreds of people on Dressrosa, Sugar both hates and fears Usopp greatly. In fact, she has extreme reactions whenever she sees someone with a long nose or anything that resembles a long nose such as sausages. As for Usopp, he hates the fact that she caused him to completely forget about Robin and became determined to prevent her from turning Luffy and Law into toys when he learned that she woke up.

Donquixote Doflamingo
Because of Usopp knocking out Sugar and freeing all the toy slaves in Dressrosa, Usopp has earned the Tyrant King's hatred as his actions led to the people realizing Doflamingo's true nature as well causing him to lose control over the island. When listing the bounties of the twelve "criminals" on the island, Doflamingo gave Usopp the highest bounty while proclaiming him as the person who "pissed him off the most".

Yasopp
Yasopp is Usopp's father. While Usopp has yet to be shown interacting with his father, Usopp has remained proud of him even though he took the path of a pirate. Yasopp also seems to care deeply about his son despite being absent for the majority of his life. It is also unclear as to how well he knows his father, as it was never said when exactly Yasopp left (except for the flashback during the fight between Usopp and Daddy Masterson with Yasopp saying "I left when he was just a baby to sail with Shanks' crew").

Usopp is revealed to be Yasopp's son. Usopp does not know much about his father, only that he is a member of Shank's pirate crew. It is said by Merry back at Syrup Village that Usopp started lying that pirates were coming to the village, hoping that his father would come back. When Monkey D. Luffy was younger, he remembers Yasopp telling stories about his son that he had left back home. Both Yasopp and Usopp are great sharpshooters, which seems to be somewhat of a shared trait. One clue is in Chapter 41, it is said Usopp's mother died not that long after Yasopp left, in the flashback, Usopp looks like a small child. Usopp either knows about his father from stories told by his mother or from actual memories, which one it is remains a mystery.

It is currently unknown if Yasopp is aware his son has also become a pirate and that he is a member of Luffy's crew, however given the fact Usopp's current bounty now shows Usopp's true name and face, it is likely that he will become aware of it (unless he was already aware of it due to him recognizing Usopp's long nose on his Sogeking poster as it was a trait he inherited from Banchina) due to the Red-Haired Pirates' tendency of keeping tabs on Luffy's (and by extension his crew's) progress as a pirate, as well as the fact that the Doflamingo Pirates defeat by the Straw Hats and their allies is headline news.

Banchina
Banchina was Usopp's mother. He deeply cared about her well being, to the point of creating his original set of lies about his father returning in an attempt to give her hope and keep her alive. Every day he would tell the same lie, that his father had returned to take them away, hoping it would keep her hopes high and help her to recover. However, she knew he would never return and before her death she told Usopp that she was glad he had gone out to sea. When she died, he suffered a deep loneliness that led him to keep on lying even though he no longer had a reason to do so. His mother's death eventually led him to develop sympathy for Kaya, and caused him to devote his time to helping her overcome her parents' death.
