On Level Four, many of the guards flee, not wanting to get caught up in Magellan's poison. Luffy laments at being so close to Ace, as Bon Kurei tries to discourage him from fighting. He tells Luffy to run, but he stands his ground and prepares to fight. Magellan informs the pair that all the exits are blocked and activates his Devil Fruit, the Doku Doku no Mi. He attacks Luffy, who manages to evade, as well as several other guards who could not escape in time. Luffy escapes onto a wooden rafter, but is hit by the heat of the level, and barely manages to dodge Magellan's Hydra. The warden hits Luffy with a Chloro ball of tear gas, blinding him, then transports himself to Luffy's position with Venom Road. Luffy is forced backward by the fierce onslaught, as Mr. 2 runs away, believing the fight impossible. In the meantime, Buggy and Mr. 3 prepare to escape onto the next level, while Luffy enters Gear Second. Sacrificing his arms, Luffy hits Magellan with a Gomu Gomu no Jet Bazooka, proving his determination to save Ace.
