Usopp/Abilities and Powers

Overview
According to Oda in a discussion with Mayumi Tanaka, Luffy's voice actress, 'no matter who joins, he always wants Usopp to be the weakest' since it would upset the balance of the story. Oda also states that this is because Usopp is the only one in the entire crew who is the closest in strength as compared to a regular human. Since early in the series he has struggled to match the physical feats of the stronger characters, and needed his weapons or ammunition to take out foes. He used to be a huge coward and often wanted to run away immediately, a trait he still carries to a lesser extent after his two years of training. This, coupled with him getting easily distracted or confused in battle have often made him less effective than his real potential as a sniper. So far, he appears to have moved past this after his training and takes better advantage of his wit and strategy.

Both his physical and mental strength have all increased greatly during the two years timeskip, as he was able to quickly dispatch all of Caesar's men on his own. While many of his attributes lie mainly in his ability to hit nearly anything he sets his sights on with his slingshot, he is now shown to be strong enough to keep both Robin, Luffy, and himself afloat in freezing water.

Marksmanship
Usopp is an extremely skilled sniper. Since early in the series, he was shown to have inherited much of his father Yasopp's exceptional marksman skills. Usopp has outstanding marksmanship abilities with the slingshot, his favourite weapon. His skills when used in conjuntion with unique ammunitions such as the Firebird Star, Usopp can deal devastating damage in long range combat. In addition to his slingshot, Usopp also has great skill in using Naval Artillery such as ship cannons and the Gaon Cannon of the Thousand Sunny.

His marksmanship is nearly unmatched, accurately hitting Spandam and some Marines from a vast distance of over a mile out-distancing even the guns the Marines had with the wind against him. In order to stop Sugar a second time, he demonstrated his ability to calculate and predict trajectory angles, influence of wind and distance, and even incorporating booster shots into his projectile; thereby allowing him to hit his target located indoors, physically located too far away to even be visualized, through a small opening in a window.

Usopp also has extremely sharp eyesight, and has on more than one occasion seen or noticed things before his crewmates. Examples of this include being the first one to see Gekko Moriah inside the stomach of the gargantuan zombie, Oars, and being the only one able to see the harpy Monet watching them on Punk Hazard.

Engineering Expertise
One of Usopp's prominent abilities is his resourcefulness and understanding towards engineering (such as easily understanding the tunnel networks made by Miss Merry Christmas). Prior to Franky joining the crew, Usopp served as the Straw Hat's sole unofficial gadgets and mechanics specialist. His creative and resourceful engineering has resulted in the creation of both the Clima-Tact and Kabuto which he can further modify with dials and pop greens. He also appears to be highly knowledgeable in chemistry, being solely responsible for manufacturing the highly innovative slingshot pellets, or "stars", that he uses for ammunition. An example of scientific knowledge is in his battle against Caesar Clown. He understood that even though Caesar Clown had the Gasu Gasu no Mi, therefore making him a Logia type, he would still explode if he was exposed to fire as he was still just gas. He also understood that a plan would not work as Caesar Clown was in control of the gases around him and that if he removed the oxygen from the atmosphere, the flame would no longer burn. For other more complex activities, such as acting as the shipwright for the Going Merry, he is largely inexperienced, as he was barely able to keep the Going Merry going doing patchwork repairs. As Franky pointed out, his skills are amateur and he barely knows how to use a hammer correctly for such jobs. After Franky joined the crew, Usopp gladly let him take over maintaining the ship, even agreeing to Franky's request to assist him. In return, Franky provided a workshop for Usopp to work on his gadgets and creations, something he is more at home with. Even Franky admitted that his skills in gadgets are incredible.

Tactical Skills
Usopp is also a highly analytical tactician with incredible ingenuity in battle, able to use deception and cunning strategies to fight and defeat enemies who are physically more powerful than him. In his battle against Chew, a fishman and an officer of the Arlong Pirates, Usopp threw a bottle of rum at him catching him off guard before Usopp destroyed the bottle and ignited the alcohol with a Kaen Boshi, setting him aflame before exploiting the chance to hit him hard with his hammer multiple times, defeating him.

While aboard the Puffing Tom, Usopp used a smokescreen to catch the CP9 off guard, allowing him to quickly grab Robin to escape, although the plan ultimately failed due to Blueno's Devil Fruit abilities and Robin's traumatic fear of the Buster Call.

Due to his ingenuity, Usopp can even defeat powerful enemies with Devil Fruit Abilities such as Miss Merry Christmas and Perona. In Alabasta, Usopp exploited Mr. 4 and his partner's teamwork against them by imitating Miss Merry Christmas's speech pattern. He took advantage of Mr 4's blind obedience to his partner command, resulting in Miss Merry Christmas taking the full force of Mr. 4's four-ton bat head on, defeating her with sheer tacticality. When fighting Perona, Usopp accurately deduced the true capabilities of her Horu Horu no Mi and correctly figured out that Perona was actually using Astral Projection, hiding her physical body inside a room instead of seemingly being intangible like a Logia.

After the timeskip, Usopp's tactical prowess significantly improved. On Fishman Island, he used different pop greens to implant a series of traps to gain an overwhelming advantage against an energy steroid enhanced Daruma, an officer of the New Fishman Pirates, and ultimately defeated him. He could stop Caesar Clown from escaping by surprising him with a pair of Seastone handcuffs that he fired at him, effectively negating his Logia powers. Usopp also has an uncanny understanding of psychological warfare. When Sugar regained consciousness and attempted to transform Luffy and Law into toys, he chose to exploit Sugar's new found trauma towards his tatabasco agonized face by having Kanjuro use his Devil Fruit to create the Bagworm, a doll shaped bullet in the visage of his Ganmen Bikkuri Bako, which he fired towards Sugar, effectively stopping her. In the One Piece Film: Gold, Usopp quickly thought of a counter measure against Baccarat's immense luck that she stole from her subordinates to gain an invincible advantage for combat. Usopp used a slot machine to fully deplete all the luck Baccarat stole, which allowed him to blast Baccarat with a SkullBomb Grass at point blank range.

Physical Abilities
While not at the same level as Luffy, Zoro, and Sanji, Usopp's endurance and willpower is considerably strong. After a major battle, Usopp tends to have severe injuries often caused by his determination to reach his goal. He will attempt to continue even with his injuries. A prominent example of his incredible durability can be observed when Usopp was hit in the face by Mr. 4's 4-ton bat, and smashed repeatedly through walls by Miss Merry Christmas, and not only survived, but was able to continue fighting. This has been seen more recently with their fight against the legendary Golden Lion Shiki where he was the only Straw Hat that managed to remain conscious after the battle, also during the Water 7 arc, He endured physical abuse from the Franky Family twice while trying to retrieve the stolen money. After being beaten up, Usopp managed to focus enough stamina to fight Luffy and later endured attacks from CP9 and the marines in Enies Lobby. In Thriller Bark; Usopp is tough enough to withstand the detonation of Perona's exploding ghosts multiple times and a ruthless beating from Kumashi, a bear zombie with immense strength, without losing consciousness. While heavily injured, he can withstand using the Impact Dial to blast the Hippo zombie despite the excruciating backlash that nearly broke his arm. At Punk Hazard, when he was attacked by a giant child, Usopp got back up almost immediately and prepared to attack. He was then suffocated by Caesar Clown with his Gasu Gasu no Mi abilities before taking a direct attack from Caesar's "Gastanet" only to come out of the massive gas explosion with a few bruises.

Another one of Usopp's attributes is that he is a fast runner, which makes him an evasive fighter. In battle, Usopp uses hit-and-run tactics and works best as part of a team where there are more physical fighters to watch his back. This is due to the fact that he is so high-strung and jumpy, and he often gives into his basic survival instincts: fight or flight (usually choosing flight), although this seems to have changed after the timeskip where he is shown to be more confident in his abilities.

Usopp's close combat abilities are still noticeably limited. Before the timeskip, Usopp admitted that he could only lift 5 kg at most and that he and Nami were dangerously underpowered and normal compared to the other Straw Hats. He prefers to use improvised weapons (like his hammers) as he lacked martial art skills.

Haki


Usopp has awakened his Kenbunshoku Haki during the latter half of the Dressrosa revolt, as he was able to see auras of Luffy, Law, and Sugar, who were in the royal palace, from the old King's Plateau near the Corrida Colosseum. With this, he was able to pinpoint Sugar's location and snipe her down from such a distance. Usopp does not yet have control over it as he just awakened it during his attack to knock out Sugar.

Artistic Skill
Usopp is also a great artist, as he proved in the beginning of the series when he designed the Straw Hat's Jolly Roger after seeing Luffy's poor art skills. A running gag involves Luffy and Chopper building simple snowmen or sand castles only for Usopp to show off his vastly superior skills with a professional work of his own, which ended up being destroyed in a comical way.

Arachnology
Usopp used to make spiders fight when he was young and knows how to handle them without being bitten by their fangs or being poisoned in the process.

Lying
Usopp is also an adept liar, which can be useful in certain situations. Although many of his lies are outrageous, they've been shown to be a useful distraction at times; especially against gullible opponents. At times, it even succeeds as a deterrence albeit for a short period of time until his enemies figure out his bluff. He often incorporates his bluffs into his arsenal with mixed results.

Hairdressing
Ussop also has some skill with hair cutting since he and Robin act as the crew's hairdressers.

Gardening
Likely due to Usopp's time with Heracles, he has gardening skills, which he uses to cultivate Pop Greens for his arsenal after the timeskip.

Medical Expertise
While working undercover as a medicine peddler in the Wano Country, Usopp has shown sufficient medical knowledge to invent an ointment named the Toad Oil which can instantly heal small cuts and stop bleeding.

Other Skills
Usopp also enjoyed boasting, much like Luffy and Sanji, that he has never been ill during his life (which impressed Vivi).

Weapons
Usopp's weapon of choice is a slingshot which he used in combination with a variety of pellets for long-range combat.

Usopp has developed other attacks unrelated to projectiles, though they are mainly jokes. These include the 5 Ton Hammer and others. After the Skypiea Arc, he has started using Dials for attacks such as using the Breath Dial to house explosive gas, using the Flash Dial to blind his foes, and using the Impact Dial to absorb and return blows.

Usopp improves his sight and/or focus with special goggles. He purchased an upgraded pair in Loguetown, but the actual scene of him purchasing them was cut out in the 4Kids dub. The scene was also absent in the original manga due to a lack of room. Since the timeskip, he has discarded those goggles, and gained a new pair which he typically wears around his neck.

Ginga Pachinko
His first slingshot also known as the "Ginga Pachinko", was his primary weapon for combat, and he had many different types of ammunition in which he carried inside a large shoulder bag of his. He also often uses eggs in order to blind his opponents and rocks whenever he runs out of ammunition (before the timeskip).

Kabuto


In the Enies Lobby Arc, Usopp introduced a new weapon, the "Kabuto", his second slingshot with five bands connected to a long staff. It has much greater power than his normal slingshot because it is powered by Skypiean Dials. Its range is enormous, and Usopp can use it to strike individual targets quite accurately from seemingly impossible distances over a mile.

The exact workings of the Kabuto are unknown, except that the five bands increase stability (and thus range), and the Dials in the instrument add spin to the ammunition similar to rifling to increase damage and accuracy, as well as allowing Usopp to choose a variety of different Dial effects to add to each shot. Usopp explained some of the workings of Kabuto to Perona during their fight, but was interrupted before he could finish.

Kuro Kabuto
After the timeskip, he uses a new slingshot called "Kuro Kabuto", which retains the five band design of the original "Kabuto". The only immediately clear difference is that it is colored black and has a smaller size (whereas the first Kabuto was a staff, the new one is nearly the same size as his original slingshot).

Grow Up Kuro Kabuto
His new Kabuto also has the ability to take on a more powerful and larger form that he calls "Kuro Kabuto Chomping Grass". After being given water, it eats up anything in the immediate area, such as rocks and boulders, to use as ammunition. This technique allowed Usopp to capture Caesar, along with Buffalo and Baby 5. He can expand it to an even larger size which he dubs "Super Grow Up Kuro Kabuto" which is useful for particularly long range attacks.

Pop Greens
After the timeskip, Usopp is shown to be very adept in using Pop Greens, as shown when he defeated some of the Impostor Straw Hat Pirates by creating a carnivorous plant that resembled a monstrous venus flytrap with tendrils. During the Fishman Island Arc, he also manages to save the crew and the Thousand Sunny from being crushed by boulders by using Pop Greens to grow sea weed like plants to trap the boulders, and again, when they encountered the New Fishman Pirates in the Ryugu Palace, he used a giant flower with a terrible smell to deter them.

In another battle with some of the New Fishman Pirate lackeys, Usopp is also seen using a particular type of Pop Green that makes bamboo shoots erupt from the ground, impaling or gouging his enemies. Later in a fight with Daruma he shoots a special exploding Pop Green into the tunnels made by Daruma's teeth, which explodes in the shape of a skull. He later uses one that transforms into a giant wolf, with the bulb that it grew from acting as its nose, which releases a stunning shockwave that is 3 meters in diameter, to finally defeat Daruma.

During his trip to Green Bit with Robin, Law and Caesar, Usopp's Pop Greens have been shown to be powerful enough to take out a full grown adult Fighting Fish.

Usopp has also been shown to be able to catch opponents off guard by using the Pop Greens in intricate ways. Also while Pop Greens are useful for battle purposes, some can also be used for utility functions (likes boats and paddles), as seen in Punk Hazard.

He keeps a small garden on the Thousand Sunny for growing more Pop Greens, in order to maintain a continuous supply of seeds.
