Allen discovered an Ancient Kingdom outpost and took the Ark Core, a control unit for Uranus, while escaping Jerome and his CP0 squad. After rescuing Ace, Luffy, Sabo, and Dadan from noble soldiers, he found that the core had detected a resonance connected to Poseidon and resolved to protect his family as the pursuit intensified.

• During rainy-season training, Allen discovered that the Power of Zhulong could bend light and alter a flying ball’s path.
• Allen followed the growing underground energy fluctuations, opened a hidden door, and found an Ancient Kingdom outpost containing the Ark Core, a control unit for Uranus.

• Allen reached Dadan’s hut, defeated noble private soldiers who were confronting her and Ace, and hurried the group to a shelter before CP0 caught up.
• The Ark Core projected a map of ancient ruins and marked a Poseidon resonance near the Goa Kingdom; Allen recognized the possible connection to Shirahoshi and vowed to protect Ace, Luffy, and Sabo.

Allen and Ace investigated a mysterious underwater signal and found a conch holding fragments of Poseidon's power, but World Government and noble forces surrounded them at sea. As Allen summoned Sea Kings to defend them, Sabo sensed an enemy attack on the shelter.

• Allen used the Ark Core to gain deep-sea adaptations and left the shelter with Ace to investigate a resonance near the Goa Kingdom.
• Allen and Ace drove off a sea monster, and Allen descended into a seabed fissure where he found ancient ruins and a crystalline conch.

• Allen detected an approaching pirate ship, and he and the brothers defeated its first attackers until the one-eyed leader summoned the Krieg Pirates, including Gin.
• Allen led the group toward Mount Colubo to escape the Krieg Pirates, then decided in a cave to investigate the Ark Core’s ancient legacy for a way out of their predicament.

Allen explored the Ark Core, uncovered secrets about the Ancient Kingdom and the D. Clan, and trained in simulations to strengthen his abilities. After sharing some of what he learned with Ace, Sabo, and Luffy, he learned CP0 elites were closing in and decided it was time to strike back.

• Allen used the Ark Core to learn that Eden was one of seven cores, the D. Clan inherited the Ancient Kingdom’s will, and Uranus was an ancient system that had gone out of control.
• The Ark Core detected an active core on Amazon Lily and increased activity in the World Government’s Uranus replica at Mary Geoise.

• Allen used the Poseidon Conch to summon Sea Kings, and the group fled toward the deep sea as Borsalino arrived and Kizaru pursued them.

Allen and his companions reached the Sea Kings’ sanctuary, where Luffy’s connection to Poseidon helped restore the Sea God Altar and awaken Sea Emperor Neptune. After Kizaru attacked and was driven away, Neptune warned them of the approaching crisis, and Allen chose Loguetown as their next destination.

• Allen and his companions entered the Calm Belt, where the Sea Kings recognized Luffy as Poseidon’s emissary and agreed to guide them to the Sea God Altar.
• At the altar, Allen and the others learned that the Ancient Weapons were mediums for communication with nature, while Luffy and Allen repaired the crystal sealing Sea Emperor Neptune.

• Allen followed the Ark Core’s signal to Roger’s execution platform, where it detected lingering energy resembling a Conqueror’s Haki.
• Allen encountered Zoro and Dracule Mihawk, then fought Mihawk until Luffy’s straw hat resonated with the Ark Core and Shanks intervened.

• Makino recognized Allen as her cousin and revealed that her father was Rouge’s younger brother; she gave Allen an Eternal Pose pointing to Amazon Lily.
• After a Marine soldier reported that Akainu had arrived with warships, Makino helped Allen and the others escape Loguetown by boat toward Amazon Lily.

Allen and his brothers reached Amazon Lily, where Boa Hancock tested Allen before allowing them to stay. After discovering the Olympus Core and learning more about the Kuja Tribe’s ancient history and the coming threat involving Poseidon, they trained on the island and then set sail for Water 7.

• Allen presented Makino’s snake-shaped token to the Kuja warriors and went ashore alone to meet Boa Hancock, who challenged him before granting the group temporary shelter.
• Allen followed the Ark Core’s signal to a hidden temple, where he found Olympus and its giant python guardian; Hancock revealed the Kuja Tribe’s ancient ancestry and the core’s role in their strength.
• Olympus projected a warning that Poseidon had awakened, a Uranus replica system had activated, Pluton’s coordinates were exposed, and a 279-day countdown had begun.
• Hancock trained Allen and allowed Ace, Sabo, and Luffy to train with the Kuja warriors, while she explained the tribe’s distrust of men and acknowledged Allen’s family alliance with them.
• Hancock gave Allen an Eternal Pose to Water 7 and a letter for Iceburg, then bade him farewell as the group left Amazon Lily.

Allen and his brothers reached Water 7, where Iceburg revealed Pluton and helped them escape a Cipher Pol 9 attack. After Allen’s bloodline awakened the battleship, they set course for Laugh Tale as the World Government prepared a larger response.

• Allen sensed Pluton beneath Water 7 and delivered Hancock’s letter to Iceburg at Galley-La Company.
• Iceburg revealed Pluton’s prototype and explained that Cipher Pol 9 was searching for a way to activate it.
• Iceburg gave Allen Pluton’s control key and sent him and his brothers toward Dock Seven as Cipher Pol 9 attacked.
• Rob Lucci confronted Allen and his brothers at the dock, and the two sides fought until Pluton awakened through Allen’s Portgas bloodline.
• Allen boarded Pluton with Ace, Sabo, and Luffy, set Laugh Tale as their destination, and escaped Water 7 as the Five Elders ordered CP0 deployed and discussed using Uranus.

Allen and the others battled Kizaru aboard the Pluton Battleship, using seastone ammunition and Pluton’s final mode to wound him before the Sea Kings helped drive him away. With Pluton depleted and the crew battered, they sailed toward their next destination as an ancient being awakened beneath the sea.

• Kizaru caught up to Pluton and attacked, damaging its shields and starboard cannons while Allen used his domain to deflect a light-speed kick.
• Ace, Sabo, and Luffy tried to limit Kizaru’s movement, while Allen blocked his attack on Pluton’s main turret and wounded him.
• Kizaru overwhelmed Allen until Sabo reminded him about seastone ammunition, and Pluton’s scattershot weakened Kizaru enough for Allen to strike him with Light and Darkness Burst.
• Allen unlocked Pluton’s Firmament Dragon God final mode and fired its Destruction Cannon, badly wounding Kizaru before the battleship ran out of energy.
• The Sea Kings surfaced to protect Pluton at Luffy’s command, and Kizaru withdrew as Pluton descended onto the sea.
• Allen and the others set course for their next destination, while an ancient being opened its eyes beneath the sea.

After recovering from the battle with Kizaru, Allen led Ace, Sabo, and Luffy to Raijin Island to strengthen their Haki and abilities through extreme training. They left for the Sabaody Archipelago stronger, unaware that the Five Elders had ordered their elimination and that Shanks sensed a storm approaching.

• Allen woke aboard the damaged Pluton Battleship and told Ace, Sabo, and Luffy they needed to rely on their own strength rather than external weapons and allies.
• Allen concealed Pluton in a seabed trench, then took his brothers to Raijin Island to train in its constant lightning.
• The four improved their Observation Haki by predicting lightning strikes, then strengthened their Armament Haki by deliberately enduring bolts.
• During a twenty-four-hour trial on the island’s peak, Ace, Sabo, and Luffy developed new ways to use their abilities, while Allen achieved the Thunder Radiance Form.
• The group departed for the Sabaody Archipelago as the Five Elders ordered the Marines to eliminate them and Shanks warned that a storm was coming.

Allen and his brothers reached Sabaody to find Rayleigh and secure a Poneglyph rubbing, but their search drew them into battles with Supernovas, the Donquixote Family, CP0, and the Marines. Rayleigh agreed to coat Pluton, while the rubbing revealed that Uranus lay beneath Marineford and that activating it would provoke the World Government’s ultimate countermeasures.

• Allen, Ace, Luffy, and Sabo fought their way past Hawkins and Diamante’s men to Shakky’s bar, where Rayleigh recognized Pluton and challenged them to prove their strength.
• After defeating the four in a test, Rayleigh agreed to coat Pluton and directed them to an auction house where a Poneglyph rubbing was for sale.
• The brothers confronted Saint Charlos when he tried to seize the rubbing, and Allen fought Rob Lucci amid the ensuing battle between the Supernovas, guards, and Marines.
• Allen touched the rubbing and received an incomplete message about the three Ancient Weapons before Admiral Fujitora arrived and Rayleigh intervened to secure the group’s escape.
• At Shakky’s bar, Allen used the Ark Core to translate more of the rubbing, learning that Uranus was beneath Marineford and that the coating would take three days.
