One Piece: Stampede

As the Straw Hat Pirates dock at Delta Island for the Pirate Fest, a grandiose gathering of swashbucklers orchestrated by Buena Festa, they're unwittingly drawn into a complex web of intrigue. Festa dispatches the pirates to a floating isle in search of a fabled treasure once belonging to Gol D. Roger, the illustrious Pirate King. The ensuing chaos unfolds as various pirate crews, including those from the notorious Worst Generation, embark on a Knock Up Stream adventure, engaging in high-stakes battles and cutthroat tactics to claim the loot. However, this spectacle is merely a ruse, cleverly orchestrated by Festa in cahoots with the enigmatic Douglas Bullet, who had spent two decades imprisoned within Impel Down's formidable walls before being freed just two years prior.

Meanwhile, Trafalgar Law uncovers the true nature of Festa's plan and narrowly escapes a brutal attack to warn his comrades on the Thousand Sunny. Robin, Sanji, Chopper, and Brook join him in investigating the conspiracy, accompanied by the stealthy Smoker. As they infiltrate Festa's lair, they uncover the shocking truth: he has conspired with the Marines to unleash a devastating Buster Call on Delta Island, resulting in its destruction and the annihilation of all who call it home.

The treasure hunt reaches its climax as the pirates discover their prize, only to be confronted by the arrival of Bullet's ship, which promptly obliterates the floating island. The pirates plummet into the surrounding bay, where Bullet claims the treasure and issues a brazen challenge to the Worst Generation crew members. Luffy and his comrades are swiftly overwhelmed by Bullet's formidable strength and Clank-Clank Fruit powers. In a desperate bid to turn the tide, Usopp intervenes, diverting Bullet's attention and allowing the other pirates to attempt a hasty retreat from Delta Island.

As the pirates scramble to escape, they're met with an unforeseen challenge: the Marine Buster Call fleet hurtling towards them. Amidst the chaos, Law's group encounters Smoker in Festa's lair, prompting Sanji to engage him in combat while Law and Robin make their escape.

As Sanji (Sanji) candidly shares the revelation that Festa orchestrated the arrival of a Buster Call, Smoker's expression contorts in shock and dismay, as he becomes acutely aware that the Marines were unwittingly manipulated. Meanwhile, Law and Robin stumble upon the enigmatic Crocodile, a former Warlord, who proposes an alliance with Law, entwining him in his scheme. In a separate development, Bullet confronts the approaching Buster Call fleet, unleashing the full fury of his awakened Devil Fruit powers, thereby annihilating the fleet and transforming the surrounding landscape into a colossal behemoth that subsequently overwhelms both pirates and Marines. Festa, ever the mastermind, reveals that the treasure in Bullet's possession is an Eternal Pose capable of guiding vessels to the fabled location of Laugh Tale, where lies the most coveted treasure in the One Piece universe - a prize that has captivated Bullet's imagination, fueling his ambition to supplant the world's strongest pirates and assume the mantle of Pirate King. Festa, intent on ushering in a new era, will stop at nothing to realize this vision.

As news of Bullet's actions spreads, Marine Fleet Admiral Sakazuki orders a second Buster Call deployment, aimed at crushing any opposition to his authority.

Sanji, Robin, Chopper, and Brook converge, with the former duo seeking an escape route from the island while the latter two embark on a mission to locate their missing friend Luffy. In a stroke of good fortune, Chopper and Brook stumble upon Luffy and Usopp, both gravely injured, and Chopper sets about treating them. Upon regaining consciousness, Luffy sets his sights on confronting Bullet, but is swiftly overwhelmed by the sheer magnitude of his adversary's powers.

The enigmatic Warlord Boa Hancock sets out to track down Luffy, inadvertently crossing paths with Buggy, Smoker, Law, and Sabo along the way. Law shares his plan to vanquish Bullet by dismantling his colossal behemoth, with Crocodile and lurking Rob Lucci joining forces to execute this strategy. United in their quest, they manage to destroy one of its arms, before Luffy, fueled by his Gear Fourth abilities, annihilates the other limb. A barrage of shots fired by Usopp subsequently brings down the remainder of the colossus.

Luffy and Bullet engage in a fierce fistfight, with Luffy ultimately emerging victorious. Undeterred, Crocodile and Rob Lucci attempt to claim the Eternal Pose, but Luffy anticipates their move, destroying the treasure before claiming he will find the One Piece alongside his crew without relying on external assistance.

As Festa broods over the collapse of his schemes, he finds himself in a precarious predicament at the mercy of Sabo (Sabo). Meanwhile, Luffy is reunited with his trusted crew members, who collectively strive to extricate themselves from their precarious position alongside other pirates. However, their escape plans are promptly derailed by the arrival of the second Buster Call fleet, whose imposing presence threatens to snuff out any hope of liberation. Yet, just as all seems lost, Smoker discreetly conveys a message to his superiors, informing them that the Buster Call's mission has been rendered obsolete, paving the way for Sabo's extraordinary abilities to facilitate the pirates' safe passage through the formidable fleet. As this unexpected turn of events unfolds, a long-held secret is revealed: the legendary Roger had disdainfully rejected the Eternal Pose, believing it was incongruous with his vision of a pirate who wouldn't be bound by conventional means of achieving the One Piece. The revelation sends shockwaves throughout Luffy's crew, leaving many in stunned silence - all except for Usopp, whose unyielding optimism remains unwavavered. With characteristic candor, Luffy asserts that had they clung to the Eternal Pose, they would have missed out on countless thrilling escapades, a notion that resonates deeply with his free-spirited nature and inspires a renewed sense of adventure within his band of merry pirates.
