When Gin refuses to kill Sanji, Don Krieg, who cannot stand traitors on his crew, releases a poison gas in the area. Luffy seems to have the advantage in the fight until Krieg pulls out his explosive Battle Spear.
Don Krieg starts to release the poisonous gas, forcing Luffy to grab gas masks for Gin and Sanji but panics as he can't find one for himself. Luckily a mask falls in front of Luffy so he wears it and is safe when the poisonous gas is released. Chefs are seen floating in the water a good distance away and they comment on how cruel Don Krieg is. After the explosion of MH5, Gin is in severe danger of dying. Luffy realizes that Gin had given up his own mask and given it to Luffy. Sanji orders Patty to help him but Zeff tells him to put the mask on Gin, giving him a few more hours to live as it will intoxicate the toxic gas within him.
A battle between Luffy and Krieg starts; Krieg shoots lots of arrows but Luffy runs through them and into Krieg's spiky shield, punching it into his face while ignoring his own injuries. Everyone watches in amazement. Zeff lectures Sanji on Luffy and his fearlessness, and how he isn't afraid of death.
After a while Krieg gets back up and takes out his Battle Spear. Luffy becomes very heavily wounded as he continues to get caught in the explosions caused by the spear. Krieg's spear soon starts to fall apart because Luffy punched it about five times. He then mocks him by saying the spear is tired and needs a rest. Zeff tells Sanji that even though Krieg has many men and weapons, he will never have the kid`s heart. Luffy says it`s his turn and the episode ends.
