Luffy: (with a big grin on his face) "Alright, Kaido! Let's show these guys what we're made of! Gomu Gomu no... Elephant Gun No Jutsu!"
Kaido: (laughing heartily) "Worororo! I like the way you think, Luffy! Let's do this! Kaido Style: Thunder Bagua No Jutsu!"
(As Luffy and Kaido charge forward, Xebec Madara and Kaguya Imu watch in disbelief.)
Xebec Madara: "What is this? Who are these clowns?"
Kaguya Imu: "I don't know, but they seem to be enjoying themselves."
Luffy: "Gomu Gomu no... Bazooka No Jutsu!"
Kaido: "Kaido Style: Breath of the Wild No Jutsu!"
(Their attacks collide, sending shockwaves throughout the battlefield.)
Xebec Madara: "What power! These guys are no joke!"
Kaguya Imu: "But we cannot be defeated! Let's show them our true strength!"
Luffy: "Gomu Gomu no... Red Hawk No Jutsu!"
Kaido: "Kaido Style: Thunder Bagua... Barrage!"
(Their attacks land, but Xebec Madara and Kaguya Imu are still standing.)
Xebec Madara: "You two may be strong, but you are no match for us!"
Kaguya Imu: "Now, it's time for us to end this! Infinite Tsukuyomi No Jutsu!"
(Luffy and Kaido are trapped in a genjutsu, but they're not about to give up.)
Luffy: "Hey, Kaido, this isn't so bad. It's like being in a dream!"
Kaido: (laughing) "Worororo! I kind of like it too, Luffy!"
Xebec Madara: "What's going on? They're not even trying to fight back!"
Kaguya Imu: "Something is not right here..."
Luffy: "Hey, Kaido, I have an idea! Let's use our ultimate attack!"
Kaido: "Worororo! I like the sound of that, Luffy! Let's do it!"
Luffy: "Gomu Gomu no... Giant Elephant Gatling No Jutsu!"
Kaido: "Kaido Style: Dragon Twister No Jutsu!"
(Their attacks break free from the genjutsu, and a massive explosion engulfs Xebec Madara and Kaguya Imu.)
Xebec Madara: "What?! This can't be happening!"
Kaguya Imu: "We... we've been defeated?"
Luffy: (panting) "That was... awesome!"
Kaido: (laughing) "Worororo! I couldn't agree more, Luffy!"
(The two victorious pirates high-five each other, as the rest of the battlefield cheers for them.)
And that's how Luffy and Kaido saved the day in an alternative version of the final war from Naruto manga![
