Many characters make their first appearance after the timeskip. The characters (in the order they were reintroduced) are: Tashigi, Smoker, Chadros Higelyges, Trafalgar D. Water Law, Eustass Kid, Rob Lucci (silhouette with a top hat), Killer, Scratchmen Apoo, Basil Hawkins, Donquixote Doflamingo, and Aokiji (silhouette). More of the Eleven Supernovas' statuses after the timeskip are revealed; according to Brownbeard, they have been causing anarchy in the New World and have been labeled, along with Blackbeard, as the "Worst Generation" of pirates. Trafalgar Law is revealed to have become a Warlord of the Sea and gained a former bounty of Beli.png440,000,000.[6] His Devil Fruit is also revealed to be the Ope Ope no Mi.[8] He is also revealed to be a former subordinate of Doflamingo. Kid has received a bounty of 470,000,000 and Killer a bounty of 200,000,000. Kid and Killer are shown attempting to form an alliance with the On Air Pirates and Hawkins Pirates. The captains of both crews' bounties have risen to 350,000,000 (Apoo) and 320,000,000 (Hawkins). Brownbeard's bounty of 80,060,000 is revealed. He has become an alligator centaur, thanks to the power of Trafalgar Law's Devil Fruit abilities. More information of G-5 branch of the Marines is revealed. Their head members include Vice Admiral Smoker, Commodore Yarisugi, and Vice Admiral Vergo, who is revealed to know at least three forms of Rokushiki. More information on Dr. Vegapunk is revealed. He used Punk Hazard as a research facility until an experiment went wrong. More of his creations are revealed also, as he created artificial beings such as Dragons that inhabit Punk Hazard. Caesar Clown was also his former colleague, and the pair had a bitter rivalry and Caesar attempts to prove he is better than him in his creation of mass-murder weapons. More of the World Government's secret experiments are shown that Caesar Clown has experimented on children and grown them larger to make them giants. As stated by Law, the World Government has been doing human growth projects for hundreds of years as a method of creating an army of super soldiers. It was later discovered that Big Mom ordered and financed the renewal of that research for her own personal reasons. Caesar's defeat at the hands of Luffy would result in the Big Mom Pirates hunting them to capture Caesar, which was later revealed to be because of Big Mom wanting Caesar to continue his gigantification experiments. Gigantification will be used in the creation of the Seraphim. Following Caesar's defeat, Tashigi would take the children to see Dr. Vegapunk to work on curing them of the side-effects of the gigantification experiments. They would later be seen again during the Egghead Arc, where they are now at the G-14 base, and the children are taking medicine which is slowly undoing the gigantification effects so they could return to their normal size. The concept of alliances gains significant momentum starting with this arc. Trafalgar Law proposes an alliance with the Straw Hat Pirates to dethrone Kaidou, one of the Four Emperors. Although Law reveals in the Dressrosa Arc that he initially had only used this as a façade to bring down Donquixote Doflamingo, this would eventually result in them continuing and expanding their alliance to form the Ninja-Pirate-Mink-Samurai Alliance, whose purpose indeed is to take down Kaidou. This alliance would remain into effect until conclusion of the Wano Country Arc, when it disbanded as their primary purpose of defeating Kaidou had been completed. The Kid, Hawkins, and On-Air Pirates are shown discussing their own alliance to bring down a Emperor, revealed to be Shanks in the Dressrosa Arc. The Emperors Linlin and Kaidou would eventually form their own alliance in the Wano Country Arc. The Underworld is officially introduced via Trafalgar Law's explanation. Donquixote Doflamingo is revealed to be a very powerful criminal underworld broker, utilizing the alias of Joker and a major part of an illegal trading web of powerful figures in the New World. Vice Admiral Vergo is also revealed to be a mole for Doflamingo. Also, more of Doflamingo's subordinates are revealed and his base of operations is a location named Dressrosa.
