Arc 6The Magnetic Calamity
Boer allied with Kaido and Linlin to forge Devil Fruit weapons and wage war on Cipher Pol, then returned to Bernia and fought Garp and Aokiji before the Superconducting Ring erupted. After surviving as a half-magnetized body in East Blue, he reached Hamlet Village and began helping its people trade salt, while Nami continued working toward her goal of setting sail.
- Boer brought Kaido to Totto Land, where he demonstrated a Devil Fruit weapon made from a captured user’s heart and Linlin’s soul infusion, and Linlin accepted their deal.
- Boer persuaded Kaido and Linlin to target Cipher Pol rather than individual ability users, then led them in destroying Cipher Pol bases and turning captured powers into living weapons.
- The Marines raised Aokiji, Kizaru, and Akainu to Admiral, while the Five Elders ordered Sengoku to mobilize against Boer, Kaido, and Linlin.
- Boer’s alliance faced Whitebeard and Red-Hair, but Boer said his revenge targeted Cipher Pol, and Shanks later negotiated terms that the Government accepted before secretly plotting to provoke Boer in Bernia.
- Boer reunited with Robin in Baltigo, but she ended their relationship, and he left after Dragon warned him that Saint Charlos’s visit to Bernia was a trap targeting Chloe and Allison.
- Boer killed Saint Roschard in Bernia and fought Garp and Aokiji, awakening his Magnet-Magnet Fruit and using the Dominator Armor before the Superconducting Ring erupted and he disappeared.
- Boer reconstructed himself in East Blue, learned to manage his magnetic powers, and reached Hamlet Fishing Village, where he offered salt and protection to help the villagers prosper.
- Boer helped Hamlet trade salt and promised to deal with sea beasts, while Arlong consolidated power in Fish-Man District and Nami escaped Omar’s coercion and resolved to keep saving money to set sail.
