The Evil Army - Transform! Germa 66

Hemmed in by the Big Mom Pirates, Bege triggers Rook In Voller Größe: Big Father, swelling into a massive castle and urging his allies inside as the Fire Tank Pirates lay down covering fire. Racing toward him, Nami, Chopper, and Carrot are knocked into cake by Caesar barreling past. Katakuri snags Brûlée from Caesar's backpack with a mochi arm, frees her after a tussle, and leads his crewmates onward, peppering the Fire Tank Pirates with jellybeans. The three Straw Hats pull loose, but Smoothie seizes Nami, Oven grabs Chopper, and Daifuku's genie snatches Carrot.

Lu Feld, having scavenged mochi earplugs, moves to loot the Tamatebako, only for Big Mom's scream to blast the chest clean off the Chateau roof. At the Vinsmoke table, Big Mom Pirates close in to finish the assassination, and Sanji sees his friends in peril. The Vinsmokes pull on their Raid Suits and turn the tide: Niji's Dengeki Blue catches bullets, Reiju's Poison Pink neutralizes arrows, Yonji's Winch Green crushes boulders, Judge's spear whips up a whirlwind, and Ichiji's Sparking Red incinerates incoming fire.

Ichiji punches Perospero aside, Niji's electric kick frees Chopper from Oven, Yonji slams Saint-Marc into Daifuku's genie to release Carrot, and Reiju's poisoned kick forces Smoothie to drop Nami, whom Sanji catches and carries to Bege. With Luffy clearing the entrance, the group makes it inside the fortress. Bege then fires on Big Mom, but Perospero shields her with a candy wall, Katakuri jams the cannons with mochi to make them burst, and Perospero pins the rolling fortress with candy. Bege concedes the assassination has failed and warns his allies they must now fight under siege.

Bege transforms into the fortress Big Father to shelter the alliance. Katakuri rescues Brûlée from Caesar. Lu Feld's attempt to rob the Tamatebako fails when Big Mom's scream hurls it off the roof. The Vinsmoke Family dons their Raid Suits and beats back the Big Mom Pirates, freeing the captured Straw Hats so all can retreat into Big Father. Bege's final assault on Big Mom is blocked by Perospero and Katakuri, and he declares the plan a failure. Bege and Perospero debut new techniques.

Part of the Whole Cake Island Arc. The anime fully depicts Bege's transformation into Big Father, his cannon fire, and Chopper's excitement, plus the Raid Suit showcase and Vito's reaction to the Vinsmokes. It also shows Big Father's tank treads and Bege trying to run Big Mom over before Perospero stops him. In the manga Yonji only tackled Daifuku's genie, but the anime first has him throw Saint-Marc into it.
