In episode 1053 of One Piece, titled "Sanji's Mutation - The Two Arms in Crisis!", the episode opens with Sanji engaged in a fierce battle against Page One, one of the Tobiroppo of the Beasts Pirates. Sanji is initially confident, using his Diable Jambe technique to deliver powerful fiery kicks. However, Page One reveals his Zoan-type Devil Fruit ability, transforming into a dinosaur hybrid, which significantly increases his strength and speed.

As the fight intensifies, Sanji attempts to use his Raid Suit, which enhances his physical abilities and grants invisibility. He activates the suit's invisibility function to gain an advantage, but Page One quickly adapts and counters with his own ferocious attacks. During the clash, Sanji's right arm is severely injured, showing visible damage and impairing his fighting capability.

Sanji struggles to maintain his composure and continues to fight despite the pain. He tries to land a decisive blow using his left leg, but Page One's dinosaur form proves resilient. The battle reaches a critical point when Sanji's right arm begins to mutate unexpectedly, showing signs of a strange transformation. This mutation causes Sanji great distress as it affects his fighting style and control.

Meanwhile, the scene shifts briefly to the larger battlefield on Onigashima, where the Ninja-Pirate-Mink-Samurai Alliance continues their assault against the Beasts Pirates. The tension rises as the alliance faces overwhelming odds, and the fate of Wano hangs in the balance.

Returning to Sanji, he makes a key decision to rely more heavily on his left arm and legs, compensating for the compromised right arm. Despite the mutation and injury, Sanji's resolve strengthens, and he pushes forward with renewed determination to protect his comrades and defeat Page One.

The episode concludes with Sanji preparing for a critical counterattack, signaling that the battle is far from over and setting the stage for further developments in his fight and the overall conflict in Wano Country.

Expanding on the ending scene by scene:

The episode opens with the people of Wano celebrating their liberation after years of oppression under Kaido and Orochi. The atmosphere is warm and festive, marking the first grand festival in over two decades. Luffy and Zoro awaken after a week of recovery, and Momonosuke, now the Shogun of Wano, orders a grand banquet to honor the victory and the new era of peace.

During the banquet, the camera shifts to the wider world, where the news of Kaido and Big Mom's defeat spreads rapidly. The bounties of the Worst Generation captains, including Luffy, Law, and Kid, are revealed to be 3 billion berries each, signaling their rising threat to the world order. The Marines announce the new Four Emperors of the Sea: Shanks, Blackbeard, Luffy, and surprisingly, Buggy. This marks a significant shift in the pirate world's power dynamics.

Amid the celebrations, a tense moment arises as Admiral Green Bull is shown making his way toward Wano. His arrival foreshadows a new threat to the Straw Hat crew and the fragile peace in Wano. Green Bull is depicted as a powerful and ruthless Marine, having defeated strong opponents in Udon prison, and his personality is reminiscent of Akainu, indicating his uncompromising nature.

The episode then focuses on Sanji, who is experiencing a severe crisis with his arms. The title "Sanji's Mutation - The Two Arms in Crisis!" reflects this personal battle. The details of his condition are not fully explained in this episode, but it is clear that Sanji is struggling physically, which adds a layer of tension to the otherwise celebratory mood.

The episode closes with a mix of hope and foreboding: Wano is free and celebrating, but the arrival of Green Bull and Sanji's condition suggest that the Straw Hats' journey and battles are far from over. The fate of the main characters at this point is:

• Luffy: Celebrated as a new Yonko, recovering but ready for future challenges.
• Zoro: Also recovering, part of the victorious alliance.
• Sanji: In physical crisis, his condition uncertain but critical.
• Momonosuke: Ascended as Shogun, leading Wano into a new era.
• Admiral Green Bull: Approaching Wano as a new antagonist threat.

This ending sets the stage for the next saga, highlighting the shifting power balance in the pirate world and the personal struggles within the Straw Hat crew.

For One Piece, season 21, episode 1053 titled "Sanji's Mutation - The Two Arms in Crisis!" produced in 2023, there is no official post-credits scene. The available information about post-credits scenes in One Piece mainly refers to the Netflix live-action adaptation, which features a scene after the episode but before the credits start, showing Smoker looking at Luffy's wanted poster. However, this is not a post-credits scene in the traditional sense and is unrelated to the anime episode 1053 from the Wano Country Arc.

Specifically for episode 1053 of the anime, there is no indication or report of any post-credits or after-credits scene. The episode focuses on Sanji's mutation and crisis with his arms, but no extra scene after the credits is documented.

Therefore, episode 1053 does not have a post-credits scene.

In episode 1053, Sanji's body undergoes a significant transformation due to his genetic lineage factor manipulation awakened during the Wano Country Arc. This mutation is linked to his use of the Germa Raid Suit, which triggers a monstrous physical change enhancing his strength and combat abilities, reflecting his Germa heritage and scientific modifications distinct from his brothers' more extensive alterations.

Sanji's mutation in episode 1053 results in a more monstrous and powerful physical form, which he uses to fight Queen. This transformation grants him enhanced strength and resilience, allowing him to better withstand Queen's attacks and deliver more powerful blows. However, the mutation also causes some internal conflict and physical strain, indicating a crisis with his two arms as they adapt to the new power.

Sanji's self-reference as a 'Seraphim' during his mutation highlights his evolving role as a warrior who follows a strict personal code and executes justice according to his own laws, especially in protecting his friends like Nami. This metaphor underscores his transformation not just physically but mentally, as he embraces a more disciplined, soldier-like identity aligned with his scientific enhancements and combat duties.

Sanji's mutation is directly connected to his Germa lineage and the Raid Suit technology he received from his siblings. Unlike his brothers, whose bodies were heavily modified, Sanji's mutation is more subtle but still significant, triggered by the Raid Suit's activation. This technology enhances his physical capabilities and unlocks latent genetic traits, marking a critical development in his character's power progression within the Wano Country Arc.

During his mutation in episode 1053, Sanji experiences a crisis involving his two arms, reflecting both physical strain and internal conflict. While his body gains monstrous strength, he struggles with the changes and the implications of becoming more like a cold-blooded assassin or soldier, which contrasts with his usual personality. This tension highlights his battle to maintain his identity and willpower amid the powerful genetic changes.
