Night Parade · Halloween
Xia Chen joined Luffy’s crew and helped recruit Zoro, Nami, and Usopp while the group battled pirates from Alvida, Buggy, and Kuro. After reaching Baratie, Zoro challenged Hawk-Eyes and was wounded, while Don Krieg threatened to take the restaurant.
Xia Chen helped the crew free Nami from Arlong, then led them through Loguetown and across Reverse Mountain into the Grand Line. The crew reached Whiskey Peak, where Zoro confronted the welcoming townspeople and Xia Chen revealed he had captured Mr. 9 and Miss Wednesday.
Xia Chen trained the crew, fought Dorry and Brogy, and secured a route to Alabasta before taking Nami to Drum Island for treatment. The crew defeated Wapol, welcomed Chopper aboard, and sailed onward after rescuing Mr. 2.
Xia Chen helped the Straw Hats expose and defeat Crocodile, then reunited with them after Aokiji captured his real body. After Vivi stayed behind in Alabasta, the crew sailed on and found their Log Pose pointing toward a ship that had fallen from the sky.
Xia Chen killed Doc Q and fought Golden Lion Shiki on Jaya, then recovered and helped the Straw Hats reach Sky Island. As the crew entered Upper Yard and battled Enel’s priests, Xia Chen moved to seize the Ark-Ark Maxim, leaving Zoro fighting Enel.
Xia Chen and the Straw Hats defeated Enel, Nami ate the Rumble-Rumble Fruit, and the crew entered Thriller Bark to help Brook reclaim his shadow. Xia Chen met the resurrected Rocks, while the crew toppled Oars before Moria revealed his strength and badly injured Luffy.
Xia Chen defeated Moria, led the crew through Water 7, and fought the World Government before being rescued by Dragon. After learning Luffy and the others were imprisoned and Ace was headed for execution, Xia Chen infiltrated Impel Down and freed allies and powerful prisoners for an assault on Marine Headquarters.
Xia Chen broke out of Impel Down, rescued Robin, and joined Whitebeard’s war at Marineford while confronting the World Government’s forces. The battle left Saint Saturn blasted apart as Xia Chen faced the truth that he was the real target of the conflict.
Xia Chen defeated the World Government’s forces at Marineford, rescued the pirates, and killed the Five Elders before faking his death. After reuniting with his crew, he recruited Franky and set plans to strengthen everyone before entering the New World.
Xia Chen gathered power by facing the guardians of Dark Night Island and learned from Hades about the origins of Divine Authority and his own status. After leaving the island, he arrived at Amazon Lily and reunited with Hancock.
Xia Chen secured Amazon Lily’s safety, granted Whitebeard his final wish for a battle, and reunited with Luffy’s crew after their training. The crew prepared to sail toward Fish-Man Island while Xia Chen searched for news of the missing Sabo and Franky unveiled their new ship.
The Straw Hats received the Thousand Sunny, reached Fish-Man Island, and became entangled in the island’s growing danger. While Hody Jones moved against them and Neptune was captured, Xia Chen descended into the pit, awakened Jörmungandr, and confronted the serpent.
The Straw Hat Pirates helped Fish-Man Island defeat Hody Jones, while Xia Chen recovered the ancient robot Vegito and placed the island under their protection. After sailing into the New World and encountering Zephyr, the crew reached Punk Hazard, where Kin'emon searched for his son and Caesar Clown fled from the intruders.
Xia Chen killed Oden and Momonosuke, helped Luo bring down Vergo, and set Doflamingo’s downfall in motion while facing Kaido in a fierce battle. The stretch left Kaido newly strengthened and Luffy trading increasingly powerful blows with Doflamingo in the Flower Field arena.
After defeating Doflamingo, Xia Chen rescued Sabo from Imu’s control and continued his journey through Gran Tesoro, where he confronted Tesoro and Stephen Gek. The Five Elders learned Imu intended to face Xia Chen, while Xia Chen joined Luffy and the others on their way to the Pirate Expo on Delta Island.
Xia Chen defeated Bullet at the Pirate Expo, but Gar used the Time-Time Fruit to send him into the past. There, Xia Chen joined the Rocks Pirates as Rocks’s equal, demonstrated his strength to Whitebeard and Kaido, and began teaching the crew Observation Haki Killer.
Xia Chen led the Rocks Pirates in an attack on a Heavenly Tribute convoy, killing two Admirals and defeating the other fighters before setting his sights on God Valley. As the Native Hunting Competition began, Xia Chen arrived ahead of Rocks and confronted the Five Elders, promising to wait until they killed Rocks before fighting them himself.
Xia Chen defeated Rocks, the Five Elders, and Imu during the destruction of God Valley, awakening god-level Haki and learning that Imu had taken Queen Lily’s body. After returning to his own era, he came upon the Straw Hat Pirates fleeing Big Mom with her Road Poneglyph rubbing.
Xia Chen returned from the past, tested his awakened Nika powers, and arranged for the Straw Hat Pirates to face Kaido and Big Mom’s forces in Wano. The arc leaves Luffy’s crew fighting the enemy elites at Onigashima as Zoro battles King.
Zoro and Sanji defeated King and Queen as Luffy and the Straw Hats fought Kaido, Big Mom, and their forces on Onigashima. Luffy awakened his Nika Form, while Chen Dragon and the World Government’s masked fighters arrived and began battling the Straw Hats and Kaido.
