"The Pact Between Men! The Fierce Fighting of Brachio Tank" is the 989th episode of the One Piece anime.

Short Summary

Long Summary
Big Mom recognizes Chopper as a Straw Hat and chases his tank into a canyon, with her forces setting up cannons and mortars to fire at the tank. Although Chopper fires back and destroys the cannons and mortars, Big Mom throws a missile at the tank from above. The tank is unharmed but it is sent flying into the air. Chopper uses the chance to fire at Big Mom's head, then throws another explosive into Big Mom's mouth. Big Mom is still unharmed and chases the tank away.

Kanjuro comes to Orochi with an unconscious, beaten Momonosuke. He states that Momonosuke attempted to escape by cutting the rope with the knife, but Kanjuro beat him unconscious. However, Kanjuro reports that he failed to thwart the Nine Red Scabbards' plans, and that the allied forces are in Onigashima. However, Fukurokuju reports that since there were no enemy ships at the port, the island was safe from enemy attacks. Still, Orochi prepares to execute Momonosuke to damage the enemy morale.

Marco's ship approaches Onigashima. He states that he is joining the raid in Oden's name.

Denjiro leads the southern forces up the mountain path only to find the map is out-of-date, as they encounter an unmapped gate. Sasaki exits the gate, and recognizes Kyoshiro, unaware that he was Denjiro. Although Sasaki was trusting of Denjiro, Denjiro's men ambush Sasaki, tying him with Seastone chains. From there, the southern forces split up into two groups; one would enter the Skull Dome while the other continues down the path.

Since Big Mom has been lured away, Kin'emon's forces are able to safely come out of hiding. They make their advance, but Nami's group is spotted by Prometheus. Meanwhile, Ulti insists that Page One carry her down the hall, but they fall down the stairs and encounter Luffy.
