Chapter 308: Arc 18: The Pact Between Men! The Fierce Fighting of Brachio Tank

Big Mom? Chopper gawked in shocked. Why is she here? She'll eat me.

"Tank Commander Chopper!" Usopp hissed. "Since we're disguising ourselves as the Beast Pirates crew, I'm sure she thinks we're her allies."

"Okay..." Chopper stammered. "Let's do it. I have a report! This is Tank Commander Chopper. I'm on security detail for the banquet."

"You're on patrol." Big Mom blinked and slid the door shut. "Wait!" she shot out of the changing room, having recalled who Chopper was. "You're that raccoon from Straw Hat's group."

"Driver Usopp, retreat at full speed!" Chopper panicked. "Retreat at full speed."

"Roger." Usopp reversed the Brachio Tank V.

"I won't let you get away." Big Mom chased the Brachio Tank V on foot.

"I knew it wouldn't work!" Chopper wailed.

"Of course not!" Usopp cried. "Retreat at full speed!" he drove the Brachio Tank V back across the bridge.

Underwater...

"Good luck." Kin'emon bubbled.

With Cat Viper...

"Are they all okay?" Izo asked, his shotgun already in hand.

"Yeah, of course they are." Cat Viper assured. "Izo."

"Thank you for everything, Cat." the marksman nodded.

"He said everyone's already entered the island, so I guess the raid is underway." Cat Viper reasoned.

"That lonely island is called Onigashima, huh?" Marco mused as their target came into view.

"Kiku..." Izo muttered.

"Anyway, you left before me but you're arriving the same time as me." Marco joked.

"Anyway, I can't believe you came, Marco." Izo turned to his former leader.

"Yeah, because I always liked Oden." Marco admitted. "It's my friend's home which he risked his life to save. How can I not help?"

"Thank you." Izo responded. "I'm indebted to you."

"Don't say that." Marco chided. "I should've done something sooner. I can't believe how much Oden's country has changed. Information about the Land of Wano doesn't cross the sea. I didn't know the once rich Land of Wano was in such state."

"It's all because of Kaido." Izo glared.

"I wonder how he is." Ace mumbled.

"I guess you're now determined." Cat Viper noted. "Let's hurry to Onigashima."

"We must catch up to everyone." Izo declared.

"But what should we do?" Marco asked. "Their raid has already started. How do we join them in the presence of the enemy?"

"Count on me." Cat Viper replied. "I have an idea."

"I have a bad feeling about this..." Ace remarked.

Meanwhile...

The fight between Big Mom and the Brachio Tank V had already started, with the Brachio Tank V firing off its cannon at Big Mom.

"How annoying those fools are." Big Mom sneered, barely fazed by the blast. "Where did you do, raccoon? You've got to pay for the wedding cake."

"Your Majesty!" an entire platoon of soldiers arrived to the fight. "We heard you want to destroy a tank, so we came in haste."

"Then, why don't you take up your positions already to smoke them out?" Big Mom suggested.

"Tank Commander Chopper, what should we do?" Usopp asked.

"It doesn't look good." Chopper peered through his binoculars. "They're each setting traps with the intent to shoot us. We're finished." he moaned.

"Tank Commander Chopper, don't you remember our purpose?" Usopp reminded. "Our mission is to rejoin Franky and the Kurosai FR-U IV at the promised hill and combine to become the General Franky. That combo is our best shot. Your animal instincts are the only hope we have to get through this situation."

"You're right." Chopper admitted. "I guess I got too frazzled. If we can't trust this Brachio Tank V, who else will?"

"Tank Commander Chopper, your order please?" Usopp returned to the driver's seat.

"Let's go." Chopper instructed. "Charge at full speed. The enemy's lying in ambush at the slit of the wall." he started formulating plans. "When I give the cue, turn around by drifting. Now!"

"Go, Brachio!" Usopp made a sharp turn.

"Fire back!" Chopper barked, Usopp dodging enemy fire and taking out a group of soldiers. "Leave it to me." he exited the cockpit, with a missile launcher on his shoulder, Usopp having dodged enemy fire. He fired his missiles, taking out another enemy group on the hill.

"There are massive cannons ahead." Usopp reported.

"Charge, don't hesitate." Chopper returned. "We'll get them at close range. Driver Usopp, show them what you've got." he shouted, Usopp driving through the smoke.

"Leave it to me." Usopp blasted the Brachio Tank V's cannon, taking out the enemy's cannons.

"They took them all down." Big Mom was impressed. "Not bad. But now I know where the raccoon is. Do you know the weak point of a tank?" she used the rock ledges as footholds to close the distance between herself and Brachio Tank V. "It's an attack from right above. Big Mom Bomber strikes!"

"She's above us." Usopp instantly spotted Big Mom. "Let's get away at full speed."

"Stop the tank!" Chopper shouted. "Trust the thickness of Brachio Tank V's armor. There must be a way out."

"Okay." Usopp relented. "Let's rest our fate on Brachio Tank V." he stopped the tank and Chopper closed the cockpit's hatch.

"Here you go!" Big Mom threw t he rocket bomb in her hand at the stationary tank. "Go to hell." she pulled back a punch when Brachio Tank V was thrown right into her face by the impact.

"Driver Usopp, now!" Chopper shouted.

"A point-blank shot." Usopp fired Brachio Tank V's cannon straight into Big Mom's face.

"Here's some extra candy." Chopper tossed a hand grenade into Big Mom's mouth for good measure.

"You guys don't really think you can bring me that so easily, do you?" Big Mom scowled. "Screw you!"

"Commander, what is your order?" Usopp gaped.

"You know what I would say." Chopper responded. "Make a strategic retreat!" he had Usopp make a run for it.

With Kin'emon...

"Even though they're frightened, they ran in the opposite direction." Kin'emon noted, his group hearing the explosions in the distance. Thank you, Commander Chopper, Drive Usopp. Let's move on. Everyone, don't let their sacrifice got to waste."
