Arc 18The League and the Kryptonite Trap
After defeating Kaido and the Impel Down escapees, Garen founded the League of Heroes, moved Fish-Man Island, and manipulated the World Government and CP0 over Kryptonite. Teach chose to protect Garen, the Whitebeard Pirates considered joining the League, and the Five Elders sent Kizaru to East Blue with Kryptonite to target the League.
- Garen and Dragon trapped Kaido in a gravity-laden tornado, and Garen killed him underwater before collecting his Devil Fruit energy and defeating the Impel Down escapees with Golden Lion's help.
- Garen persuaded Dragon and the Revolutionary Army to form the League of Heroes, with Garen as Speaker-General and Dragon as Deputy Speaker, while the Five Elders learned that Wano had been taken and Golden Lion and Stussy had joined Garen.
- Garen revealed his fabricated history of Demacia to Robin and asked her to create fake Laugh Tale ruins, then used Golden Lion's Float-Float Fruit to lift Fish-Man Island into the sky and move it toward Wano.
- Garen staged a chance for CP0 agents led by Raiga to steal Kryptonite, but Ace and Teach joined their mine expedition, where Bell took the stone and the agents escaped through a collapsed tunnel.
- Bell revealed himself as Thunder God and, with Raiga, used Kryptonite to subdue Garen, but Teach crushed the stone and helped Garen, choosing not to betray him.
- Raiga and Bell used an artificial moon to trigger Bell's Sulong form, but Garen and Golden Lion pursued them, Teach helped bring down Bell, and Garen later took Bell's Devil Fruit energy.
- Garen offered the Whitebeard Pirates a League membership that would let them keep their flag and governing system in a special zone, and Ace agreed to ask Whitebeard to consider it.
- After two CP0 agents brought Kryptonite to Mariejois, the Five Elders chose Kizaru to lead an operation in East Blue and ordered him to carry one piece of the stone.
