Arc 6The Marineford War
Natsu joined Whitebeard’s campaign to save Ace and restored Whitebeard’s strength with Hashirama Cells. As the battle at Marineford escalated, the Uchiha arrived in force, while Natsu’s whereabouts remained unknown.
- Fugaku brought Drake Vallen into the Uchiha’s underground laboratory, where Drake and the clan’s researchers began sharing expertise, while the Uchiha took control of three islands and reorganized their forces.
- Natsu awakened his Sage Mode and set out rules for marriage into the Uchiha Clan, then learned that Ace would be executed at Marineford and prepared to help Whitebeard rescue him.
- Natsu joined Whitebeard’s fleet, explained the risks of a Hashirama Cells transplant, and operated with Drake to restore Whitebeard’s failing body before the fleet sailed for Marineford.
- Sengoku strengthened Marineford’s defenses and recalled the Admirals, while Garp visited Ace in Impel Down and struggled with the order to stop Whitebeard.
- Whitebeard arrived at Marineford with his strength restored and fought through the Marines’ defenses, keeping the Admirals occupied as Sengoku watched for Natsu’s spatial abilities.
- Garp confronted Whitebeard, while Luffy arrived with the Impel Down prisoners and declared that he would protect Ace, and Sengoku revealed Ace’s parentage and Luffy’s connection to Dragon.
- The Marines raised the encircling walls and deployed Pacifistas, but the Uchiha attacked and destroyed more than half of them before Fugaku appeared in a towering Susanoo.
- Sengoku and Kizaru searched for Natsu as the Marines recognized the Uchiha threat, while Sakazuki urged them to stand firm.
