As per Trafalgar Law's account, the Underworld could be compared to a crime syndicate of tremendous scale, essentially gathering the most influential figures of the world (such as the Four Emperors, Seven Warlords of the Sea, World Nobles, and Super Rookies), though any individual partaking in its activities usually acts autonomously and for their own benefit. Although it is mainly active in the New World, it may also exist in other regions, like North Blue and West Blue.
Above all, the Underworld is based on a principle of absolute secrecy, and all connections are shrouded in mystery. Ironically, this is mostly so as to avoid to catch the Marines' attention, since some agreements are sometimes common knowledge around the Underworld. Furthermore, to ensure the anonimity of the different participants, it is customary to take an alias on.
Due to the Underworld being highly secretive, it allows the existence of illegal, or morally reprehensible activities, such as slave trading, weapons smuggling and goods dealing. It is also very active regarding mercenaryism and hitmen for hire.

The most influential man in the Underworld was previously said to be Donquixote Doflamingo under the alias Joker. However, with the dismantling of his criminal enterprises by Monkey D. Luffy and Trafalgar D. Water Law and his arrest by the Marines, his connections to the Underworld have been permanently severed. Other important figures are the Emperors of the Underworld (裏社会の帝王達 Urashakai no Teiō-tachi?), who are often the leaders in their specific activities.
CP0 is shown to have a history in the Underworld, having been previously involved in deals with child traffickers such as Mother Carmel in the past. She provided strong children to the World Government and even planned to sell Charlotte Linlin with CP0 acting as a go between before her disappearance and death. Additionally, Stussy, one of the Underworld Emperors known as the Queen of the Pleasure District, is actually a deep cover CP0 agent which presumably allows CP0 to both monitor and give it some control over it as Stussy was able to convince fellow Emperor and media tycoon Morgans to publicly frame Du Feld for the theft of the Tamatebako with a falsified story so she could obtain it. Another CP0 agent known to be involved in broker affairs, at least as an observer, is Rob Lucci.

Over a century ago, Carmel, otherwise known as the "Mountain Witch", started an orphan trading business. Every two years, she would sell her best "products" to the World Government, who would enter the ranks of either of the Marines or of the Cipher Pol groups. 100 years ago, she made up an act with the World Government in order to be regarded as a Holy Mother, win the Giants' trust and enter Elbaf. This was all done in order to trade John Giant over to the Marines. Then, 63 years ago, as she was still living in Elbaf and running the Sheep's House, she encountered a young Charlotte Linlin and wanted to sell her as well to the Marines, considering her as her "best product ever" and contacted the CP0 in this objective..
At some point in the past, West Blue fell under the control of the Five Families of the West, one of which was led by Capone Bege. Bege had the habit of targeting the leaders of rival families in order to leave their organizations in disarray due to power struggles, as a way of amusing himself. Once Bege got bored of the gangster lifestyle, he set out to sea and started employing similar tactics to rival pirate captains, becoming infamous enough to earn a place in the Worst Generation.
The Sabaody Archipelago also had a tradition of slave trading, notably in the Human Auction House situated on Grove 1 and owned by the previous most influential man in the Underworld, Joker. Several years ago, Doflamingo was acknowledged as the principal figure of the Underworld, and made use of his country, Dressrosa, as a smuggling platform for his purchasers. 4 years ago, Caesar Clown became his subordinate after escaping from the World Government's grasp. Joker had Caesar Clown produce SAD, that would be used in a factory on Dressrosa to cultivate artificial Devil Fruits, which would in turn be sold to the Emperor Kaidou.
The Franky Family also often sold the valuables procured from ship dismantling on the black market.
The Warlord Crocodile made use of Dance Powder to provoke a terrible drought for the Arabasta Kingdom that led to a civil war that would allow him to get his hands on the country. When he and his criminal organization were ultimately defeated by the Straw Hat Pirates, his plan was uncovered and he was dismissed from the Shichibukai.

Upon visiting the Sabaody Archipelago, the Straw Hat Pirates were confronted to the discrimination against fish-men and to the slave trading tradition of the archipelago. In fact, their mermaid friend Camie ended up being captured and sold in the Human Auction House to a World Noble, Saint Charlos.

During the Timeskip
Punk Hazard Arc
During Caesar Clown's broadcast for the selling of Shinokuni, the Straw Hat Pirates, Trafalgar Law, and Smoker's G-5 unit defeated him in order to deprive Doflamingo of his supplier of SAD, the main ingredient in the SMILEs production. Several major figures in the underworld, some hailing from the Kid Pirates, Big Mom Pirates, and the Beasts Pirates, witnessed Caesar Clown unleashing the deadly weapon on his own subordinates as a means of showing off its destructive potential, but when the scheme failed, his prospective buyers were left in disorder.
The defeat and kidnapping of the scientist caused a riot in the underworld and characters such as the Emperor Big Mom and Jack were informed about it. Later, Law blackmailed Doflamingo into resigning from his Warlord position in exchange for Caesar's return and not become a target of Kaidou's fury. However, Doflamingo was able to deceive Law with false news.
Caesar Retrieval Arc
The pirate, Breed, attempted to kidnap Caesar from the Straw Hat Pirates in order to produce his own SMILEs and build up a Zoan army. He was defeated by a combo attack of Luffy and the Kung-Fu Dugong, captain of the Sea Animal Pirates.
Concludes non-canon section.
A lot of Underworld personalities (to name a few: the Funk Brothers Bobby and Kelly, Suleiman, Hajrudin) gathered in Dressrosa and competed in the Corrida Colosseum in order to win the Mera Mera no Mi. Don Chinjao, Sai, and Boo of the Happo Navy also took part in the tournament in order to investigate Doflamingo's weapons smuggling operation, which was supporting a nation in its war with the Kano Country.
They finally discovered that the weapons were traded beneath the country, in the Underground Trade Port, to various customers over the world. In this port was also situated the SMILEs Factory, that produced SMILEs which would in turn be sold to the Emperor Kaidou. However, the factory was later destroyed by Franky and the Tontatta Tribe, ruining their business.
Upon Joker's defeat at Luffy's hands, all of his buyers were negatively impacted, and amongst them the Beasts Pirates in particular. Additionally, Doflamingo's defeat and subsequent arrest left a massive power vacuum in the Underworld that caused many parties such as Buggy and the Pirate Dispatch Alliance scrambling to make a bid for power. Doflamingo himself stated that a global scale war between all the major powers in the world, among which are the Revolutionary Army, Four Emperors, Marines, Seven Warlords of the Sea, and the Worst Generation was inevitable. In the meantime, the Revolutionary Army also gained many victories around the world due to how many countries were involved in arms dealing with Doflamingo.
Hajrudin also left Buggy's Delivery in order to join the Straw Hat Grand Fleet along another Underworld mercenary, Suleiman. On the orders of Kaidou, Jack attempted to retrieve Joker from the Marines, but failed after clashing with Sengoku and Issho and sinking two Marine battleships.
Whole Cake Island Saga
Upon arriving at Zou, the Straw Hats learned that Sanji had been kidnapped by Capone Bege on the orders of the Emperor Big Mom while they still were at Dressrosa. Indeed, the captain of the Big Mom Pirates had planned, together with Sanji's father to wed Sanji to one of her daughters, Charlotte Pudding, so as to seal the alliance she was seeking to form between the Charlotte and Vinsmoke houses.
When meeting up with Pekoms, the Straw Hats learned that Sanji's family is a family of killers, and that its patriarch is a very influential man throughout the Underworld, capable of influencing the Marines' bounty system. The mink also told them about the Germa 66, the mythical evil army led by the Vinsmokes and operating as mercenaries.
As the Sanji Retrieval Team then set off to Totto Land to retrieve Sanji from his political wedding, Kaidou learned of Jack's failure and was terribly mad at Luffy and Law upon realizing he could no longer obtain artificial Devil Fruits.
Whole Cake Island Arc
Three days prior to their brother's wedding, Vinsmoke Ichiji and Niji led a regiment of Germa 66 in order to stop Broc Coli Island's civil war, that had been ongoing for two years. After successfully doing so in less than four hours, they departed for Whole Cake Island where the wedding ceremony was to be held.
In the meantime, the Germa Kingdom had begun to assemble at Whole Cake Island so as to attend the wedding between Sanji and Pudding. However, unbeknownst to Judge, Big Mom had actually planned to slaughter the whole Vinsmoke Family during the ceremony, so that she could obtain the mighty Germa 66 for herself.
In parallel, Family of the West leader Capone Bege, who had previously aligned himself with the Big Mom Pirates, plotted to take Big Mom's head during the tea party. Availing of being in charge of the event's security, he allied himself with the Straw Hat Pirates and planned to poison the Emperor after having destroyed the picture of Mother Carmel.
On the day of the wedding, the Emperors of the Underworld, who had been invited by Big Mom, showed up on the island and were greeted by Charlotte Perospero, who took them to the wedding venue atop Whole Cake Chateau. As the tea party began, they showed interest in the Tamatebako, and proceeded to offer Big Mom the presents they had brought for her. They then enjoyed themselves in the party, until Luffy and the Straw Hat Pirates trespassed into the event. After some of them witnessed Jinbe leaving the Big Mom Pirates, Big Mom unleashed a powerful scream, forcing them to rely on earplugs.
As chaos ensued, Du Feld seized this opportunity to try and rob the Tamatebako. However, Big Mom's powerful scream projected the chest on the edge of the Whole Cake Chateau. Du Feld then tried to reach it again, but he was discovered by Stussy, who shot him and revealed herself to be an undercover agent from CP0. She knew that Morgans was eavesdropping, and demanded of him to report to the world that it was Du Feld who stole the Tamatebako. However, the prized treasure chest suddenly fell to the base of the Chateau, exploding and causing it to topple over.
As the Whole Cake Chateau was about to fall over, Stussy used Geppo in order to get out of harm's way, while Morgans tried to escape as well as he could. Both of them were later discussing with Charlotte Mont-d'Or and Tamago, and Stussy revealed to them that it was the Tamatebako that had caused the Chateau to collapse. Stussy and Morgans later snuck away from Whole Cake Island. While riding in a balloon, Morgans shared with Stussy his belief that the next Pirate King would be born from the Worst Generation.
- Both Donquixote Doflamingo and Smoker insinuate that Kuzan may have dealings in the underworld, though Kuzan neither confirms or denies this.
