Nami tries to fight Enel but her efforts are in vain. Meanwhile, Usopp and Sanji get onboard the Maxim and separate hoping to distract Enel. Usopp gets to Nami first and they try to escape using the Waver. Enel gets angry and tries to use God's Judgment but is stopped by Sanji, Sanji then takes the blow for Nami.
Unfazed by the previous attack, Enel comments on Ussop successfully making his way to the deck. Ussop frantically looks around for Sanji and runs away once he realizes that the latter has yet to make his way to the deck. Nami scolds Ussop for cowardliness. Doubting himself, Ussop debates on whether or not he should go back and face Enel. Ussop decides to face Enel once more, but he gets struck by a great flash of lightning. Ussop asks Nami for her to save him, but a furious Nami grabs Ussop by the collar and yells at him because he was supposed to be rescuing her. Enel strikes them again with his lightning, missing them only by a small margin.
