Thrown into the Blue

 "How dumb! Why did I let them do that!?" Zoro snapped mid-run, shaking off the shame. Then he muttered under his breath, "No... let's just forget it ever happened..."

"If only you guys had joined in! We could've become the robot warrior—BIG EMPEROR!!" Franky howled from inside the crater, voice full of heartbreak.

Chopper sniffled dramatically. "I never saw this betrayal coming!"

"Luffy would've docked with us without question!" Usopp yelled, eyes brimming with betrayal.

"Never mention 'docking' again," Robin said flatly, walking away with the dead eyes of someone who's seen too much.

Mel fell in step beside her, arms crossed. "Yeah... it kinda sounds wrong anyway."

Franky, Chopper, and Usopp pulled themselves from the rubble, covered in dust and pride, shouting in unison:
"LET'S START OVER, DAMN IT!!"

"Franky! I'm borrowing this!" Zoro suddenly shouted, stabbing his katanas into a tall white column.

"AH! My Heavy Nunchaku! Take it!!" Franky replied dramatically.

Sanji launched a rock at Oars' face to distract him, then zipped around the giant's massive body. "Robin! I'll get his left arm—lock his joints!"

Robin smirked coolly. "Got it."

Nearby, Mel had both arms raised as she bent massive streams of water out of the forest trees. She sent sharp water slices flying at Oars to draw his attention, the attacks slashing harmlessly across his towering body—but the distraction worked.

Zoro, dragging the white column behind him, ran toward Sanji. "Hey! Give me a boost!"

"With that thing?!" Sanji barked, eyes wide. "You're insane!"

"Just do it!" Zoro yelled back.

Zoro leapt—Sanji grit his teeth and launched him skyward.

"Armee de l'Air: Power Shoot!!"

Zoro soared through the air, white column spinning with momentum before he brought it crashing down:
"DAI GEKKEN!!"

The blow smashed into Oars' left arm, sending the giant lurching backward.

"Cien Fleur: Big Tree!" Robin declared as dozens—no, hundreds—of arms sprouted from Oars' back, forming one enormous limb that snatched and twisted his right arm behind him, locking it painfully in place.

Mel's voice rang out like a war cry:
"Water Whirlwind of Fashion Crimes!!"

A spiraling torrent of water wrapped around Oars' one remaining leg, making balance impossible.

"Wah! He's gonna fall!"
"He's falling!!"

Oars' eye flickered in panic as he tried to shift his weight—but it was too late.

"TAKE A GOOD LOOK AT MY IMPROVISED MIDAIR STAIRCASE!!" Franky bellowed.

He and Chopper had built an on-the-spot staircase from planks and debris. Franky sprinted up it, Chopper right behind him.

"Franky Sky Walk!"
"This staircase won't last long! Let's go, Chopper!"

"SUPER FRAPPER GONG!!"
Their fists slammed into Oars' jaw simultaneously, the shock rattling his skull and body. He staggered wildly, unable to regain footing.

"No matter how big he is," Chopper shouted, "the human body's weak points don't change! If the jaw takes damage, the brain shakes too!"

"He's only got one leg left!" Sanji sped forward, legs glowing.
