Episode 1016

"The Battle of the Monsters! The Three Stubborn Captains" is the 1016th episode of the One Piece anime.

Short Summary
Kaidou gets up, but Luffy, Law and Kid begin to quarrel amongst themselves. Meanwhile, Sanji is caught and interrogated by Black Maria in what he calls “heaven.”

Long Summary
As Big Mom scoffs at Luffy's declaration, Kaidou is surprised that Luffy was able to injure him, a feat only done by a few of the most powerful pirates. He unleashes his Raimei Hakke move, and Luffy mostly avoids the attack. Big Mom attempts to intervene but Zoro cuts Prometheus in half, though Prometheus survives and is reunited.

Kaidou attempts to strike Luffy off guard but Law saves him. He, Luffy and Kid begin bickering just as Prometheus shoots fireballs at them. Luffy suggests a contest where the last to dodge the fireball would win. Since they were focused on winning this contest, they all ended up being hit by the fireballs. Although they all emerge from the rubble, Zoro and Killer are left to battle Kaidou. They charge at Kaidou and manage to shallowly cut him.

In the banquet hall, Sanji is kept bound by Black Maria but is too charmed by the women to attempt to escape. Eventually, he decides to free himself by burning the webs with Diable Jambe flames, then uses the webs to fight off the ladies. However, he could not find himself to attack Black Maria, and Maria starts interrogating him about his crew's whereabouts, especially Robin.

The three captains declare they will defeat Kaidou. Luffy transforms into his Gear Fourth form, Kid gathers metallic objects and Law creates a Room. They prepare for battle, and Kaidou calls them "monsters."
