Crocodile arrived at Skypiea and learned that Gawain had built Avalon, a warship based on the Pluton Blueprint and more powerful than the original. As the world’s forces gathered to attack Britannia, Katakuri received Crocodile’s warning that Britannia had an Ancient Weapon and was urged to flee.

Gawain and Britannia unveiled Pluton, a ley-line-powered Ancient Weapon built in just over two years, and used it to devastate the forces surrounding Britannia. The Five Elders realized the threat Pluton posed, just as an unfamiliar figure entered Mary Geoise.

• Vegapunk and Britannia's officers gathered around Pluton, while Franky served as its central control system and Gawain ordered him to fire.
• Avalon unleashed a massive pillar of light that spread across the surrounding seas, prompting Akainu, Kizaru, Katakuri, and other forces to retreat.

Blackbeard delivered the Five Elders an ultimatum on behalf of an unnamed ruler while Avalon annihilated the fleet attacking Britannia. As the Marines reckoned with Britannia’s power and debated humanity’s escape from the rising sea, Tsuru insisted that reaching the moon was the only lasting solution.

• Blackbeard appeared before the Five Elders, told them to give up their positions after Britannia’s affairs were settled, and warned that their lives depended on what they did next.
• Avalon’s bombardment devastated the pirate fleet surrounding Britannia, leaving wreckage, burning survivors, and cries for help across the sea.
• King and Queen washed ashore gravely wounded; Queen urged King to stop fighting Knight Gawain and think of himself, then died as King lost consciousness.
• Akainu and Aokiji assessed the destruction and questioned whether Britannia could be a better choice than the World Government, while Akainu doubted that the promised escape ships to the moon existed in the claimed numbers.
• Sengoku argued that humanity had no choice but to rely on whoever could survive the coming flood, and Akainu suggested that floating islands might provide refuge.
• Tsuru rejected floating islands as only a temporary refuge and declared that reaching the moon was the only way to preserve humanity until the seas receded.

Akainu accepted the World Government’s order to attack Britannia for the sake of humanity’s survival, but he and the Marines considered joining forces with Gawain instead. Meanwhile, Gawain used the Float-Float Fruit to raise Britannia into the sky, while Imu learned of the continent’s flight as the final battle approached.

• Saturn ordered Akainu to invade Britannia, arguing that the Moon Ark was humanity’s only salvation and that Gawain would personally intervene.
• Akainu rejected the idea of sacrificing his Marines for the Celestial Dragons and asked whether they could seize places aboard the Moon Ark for others; Aokiji suggested allying with Gawain.

• Imu gathered his forces in Mary Geoise and declared that their performance in the coming battle would determine who could board the Moon Ark.
• Gawain confirmed that Kuro had evacuated Britannia’s civilians, then used the Float-Float Fruit and ley-line energy to lift the continent from the sea.
• Big Mom recognized that Gawain was raising all of Britannia into the sky, and a CP0 agent reported the continent’s flight to Imu.

Gawain lifted Britannia into the sky, giving survivors a possible refuge from the rising sea and the World Government’s Moon Ark. As pirates and Marines considered what the feat meant, Sengoku realized it might connect to Britannia’s legend of immortality.

• The Marines debated whether Gawain had used the Float-Float Fruit, and Garp wondered how many people Britannia could shelter.
• Sengoku realized Gawain may have chosen Britannia for more than its suitability as a battlefield, and Tsuru connected his insight to the kingdom’s legend of immortality.

As Britannia rose into the sky to shelter humanity from the sinking world, Sengoku and the Marines turned against the World Government, while Luffy and Kid headed toward the flying continent. Imu saw Britannia's ascent and struggled to understand how Gawain had achieved it.

• Sengoku explained that Gawain had pursued the Float-Float Fruit to raise Britannia into humanity's last refuge, and Aokiji and Kizaru confirmed that Britannia had no nobility or Celestial Dragons.
• Garp urged Sengoku to fight the Celestial Dragons, and Marines including Doberman, Kuzan, Onigumo, and Akainu threw their Justice cloaks into the sea and resolved to oppose the World Government.
• Sengoku warned that Britannia would become the next battlefield as Imu's malice swept toward the flying continent, and Akainu told the Marines to act according to their beliefs.

• Imu watched a projection of Britannia above a sea of clouds and questioned whether Gawain had used the Float-Float Fruit or another means to raise the continent.

Imu and the Five Elders feared that Gawain had planned to secure eternal life and raise Britannia above the coming flood, while Gawain successfully lifted the continent into the sky. He then ordered Avalon to fire toward Mary Geoise, as Kizaru realized too late that the weapon was targeting the Celestial Dragons' home.

• Garling proposed that Gawain had found a substitute for the Soul-Soul Fruit and intended to make Britannia immortal before lifting it above the flood.
• Saturn and Imu concluded that Gawain had manipulated the Marines, Blackbeard, and other powers as part of a long-term plan, while Blackbeard admitted he had served as Gawain's scapegoat.

• Gawain approved Bullet's suggestion to attack Mary Geoise, and Avalon charged up while the approaching Marine fleet watched.
• Kizaru flew toward Britannia to propose an alliance against the World Government, but Avalon fired a beam toward Mary Geoise before he could reach Gawain.

Imu vowed to seize Britannia, but Gawain’s Ancient Weapon destroyed Mary Geoise in a massive strike. As Dragon and the Revolutionary Army feared the loss of the Moon Arks meant humanity had no hope, Sabo reported that Britannia was rising into the sky.

• Imu and the Five Elders prepared to seize Britannia, confident Imu could defeat Gawain.
• A barrage of Ancient Weapon beams struck Mary Geoise, vaporizing Pangea Castle, the Celestial Dragons, and much of the Red Line.

• Sabo called Dragon and reported that Britannia was flying, revealing Gawain had prepared a way to survive the sinking world.
• Dragon told Sabo that Mary Geoise had been erased and an enormous gap had been carved into the Red Line.

After Mary Geoise was destroyed, Imu and his surviving allies escaped to Britannia, where they confronted Gawain and his assembled fighters. Gawain challenged Imu to face divine punishment, while Imu vowed to take Gawain’s body and power.

• Gawain appeared before Imu and challenged him to face divine punishment, while Imu declared that he would take Gawain’s body and power.

Gawain took Imu away from Britannia and repelled her attempt to possess his body, identifying her as the will inside a Mythical Zoan Human-Human Fruit. Meanwhile, the World Government’s forces were overwhelmed by their opponents, and Saint Ethanbaron’s plea for Imu’s help ended as a vast black aura erupted around him.

• Gawain recognized that Imu wore Queen Lily’s face, then seized her and carried her away from Britannia to prevent their fight from sinking the island.
• The battle erupted across Britannia as Sanji attacked Saturn, Zoro fought Saint Nusjuro, and the other combatants engaged their assigned opponents.
