Long Summary
At the royal palace's first floor, after fighting through several of Doflamingo's men, Rampo, Kabu, and Thunder Soldier were intercepted by Gladius. The two dwarves attempted to attack him in order for the Thunder Soldier escape, but the officer effortlessly caught them. Gladius then attacked them with his Devil Fruit powers, knocking them out with the explosions by rupture of his arms. He then went after Thunder Soldier, stating he can't outrun him as a toy. He tackled the toy soldier from behind and, while explaining his ability, inflated the soldier's head. Right before it exploded, Luffy knocked Gladius away with a Jet Stamp, saving Thunder Soldier from certain demise. Luffy was about to continue the fight with the officer, but Viola pulled him away, stating that Gladius was too dangerous. Upon seeing Viola, Gladius ranted about her betrayal and exploded his helmet, hurting her with the helmet's shards, managing to wound Viola which forced Luffy to carry her. Seeing no stairs to advance further up, Viola, Luffy, and Thunder Soldier jumped out a window and Luffy used his leg to stretch to the second floor conveniently outside the Room of Suits. As they overheard Doflamingo trying to get Law to tell him what the Straw Hats' plan was, Luffy asked if he can attack Doflamingo, only to be denied and told to wait by Viola, while Thunder Soldier places his faith in Usopp to gon with the plan.

After losing sight of them, Gladius ran into Kin'emon, disguised as the Doflamingo with Wicca hiding in his pocket. Fooled by the disguise, Gladius informed him that Kanjuro had disappeared from the scrap house.

At the underground trade port, Robin used her Devil Fruit powers in an attempt to knock out Sugar with the spice the dwarves were going to use. Unfortunately, she let her guard down for a moment and Sugar touched one of her arms, transforming her into a toy.

Trebol has had enough and attempts to crush the Dwarves with a boulder while Usopp watches in horror.
