"Army of One," the 990th chapter, sees the Mink rulers go Sulong against Jack, King clamping down on the Tobiroppo, and X Drake exposed as a traitor before he leaps to Luffy's side after the Straw Hats trade blows with the Numbers.
Freed from the tree that bound him, Sasaki learns the assault inside the Skull Dome is already underway and that Kyoshiro, secretly Denjiro, has betrayed the Beasts Pirates. On the rooftop, the Sulong-empowered minks tear through Kaidou's troops, yet Jack's mammoth form overpowers them. When Kin'emon moves to join in, Inuarashi and Nekomamushi wave the other Scabbards off and transform into Sulong themselves to take the elephant on directly.
On the castle balcony, King berates Queen over the mass escape from the Prisoner Mine, then radios the Tobiroppo. In a nearby room, X Drake urges Basil Hawkins that the chaos is the moment to switch sides, but Hawkins declines and predicts a certain man has only a one percent chance of seeing tomorrow. King informs the Tobiroppo that roughly 5,000 intruders face their 30,000, and he cancels their shot at challenging an All-Star after capturing Yamato.
Down on the Live Floor, the Udon escapees and Denjiro's yakuza collide with Beasts Pirates, the Mimawarigumi, and the Oniwabanshu, urging the Straw Hats to save their strength for the castle. The Numbers spot them anyway; Zoro shears through a mace while Jinbe blocks it from crushing their allies. Comparing the giants to Oars from Thriller Bark, Luffy shifts into Gear 4, a form Hyougoro likens to a Wisdom King.

When I first decided to commit to watching One Piece seriously, I knew I was embarking on one of anime's longest and most beloved series. With over 100...
Elsewhere, Queen and Who's-Who beat Drake after Hawkins grills him over freeing Law, all three intending to kill him. Drake smashes a window and drops to the Live Floor, striking Juki with his blade and axe just as Luffy lands his own attack on the Numbers. Now an open enemy of the Beasts Pirates, Drake asks to fight alongside Luffy. The chapter confirms Hawkins is on Onigashima and that the Tobiroppo's All-Star challenge is off. The cover serial shows Bege's crew aiding Pound.
