The air was thick with the clash of Haki, the scent of blood, and the screams of the fallen. In a vast chamber littered with shattered pillars and scorched earth, Missandei, her dark curls tied back, stood resolute.
Opposite her loomed Jack, his massive frame radiating menace, his ancient zoan mammoth form ready to crush all in his path. The hall shook as their battle began, a clash of nature's wrath against a beast's might.
Missandei, her eyes sharp with determination, channeled her Mori Mori no Mi, the forest floor beneath her erupting with roots and vines. Her voice was steady, laced with defiance. "Jack, your rampage has crushed Wano's spirit for too long. For Wano's people, I'll bind your strength and end your terror with my forest's might."
Jack (roaring, trunk raised): "Puny bitch! I'm Jack the Drought, Kaido-sama's unstoppable force! My mammoth strength'll trample your weeds, and Wano's mine to crush! You're nothing but a twig under my feet!"
Jack transformed fully, his ancient zoan mammoth form towering, tusks gleaming with Armament Haki, his massive weight cracking the stone floor. He charged with Mammoth Stampede, his Haki-coated tusks swinging like battering rams, shattering pillars in his path.
Missandei dodged and unleashed Verdant Snare, thick vines bursting from the ground, coiling around Jack's legs.
The mammoth roared, snapping the vines with brute force, but Missandei followed with Thorn Barrage, Haki-infused thorns erupting from the floor, piercing Jack's hide, blood dripping.
Jack swung his trunk in Tusk Swing, a Haki-charged arc that cleaved through vines and stone, forcing Missandei to leap, her cloak torn by flying debris. She countered with Forest Surge, roots surging like spears, their Haki-coated tips stabbing Jack's flanks, drawing a bellow of pain.
Jack's durability was immense, his Iron Hide, a Haki-enhanced defense, shrugging off most strikes. He stomped with Calamity Quake, the ground splitting, shockwaves buckling the chamber.
Missandei vaulted over the cracks, her Vine Shield absorbing the impact, though her arms trembled from the force.
Missandei pressed forward, her Sylvan Wrath summoning a storm of Haki-infused branches that lashed Jack's face, one gashing his eye, blood streaming.
Jack roared, charging with Tusk Drill, his spinning tusks glowing with Haki, aimed to impale her.
Missandei sidestepped and struck with Bramble Fang, Haki-coated roots piercing Jack's shoulder, slowing his charge.
The mammoth's raw power pushed her back, his Trunk Smash slamming the ground, sending stone shards flying. A shard grazed Missandei's side, blood soaking her tunic, but she stood firm, her forest powers undeterred.
The battle intensified, Jack's mammoth form a relentless force, his Haki-enhanced attacks shaking the chamber like an earthquake.
Missandei countered with endless growth, vines and roots reforming faster than Jack could destroy them. She unleashed Emerald Tempest, a whirlwind of Haki-infused leaves and thorns that slashed Jack's hide, tearing gashes across his legs.
Jack retaliated with Mammoth Roar, a Haki-charged bellow that shattered her vines, the sonic force knocking Missandei back, her ears ringing, blood trickling from a cut on her forehead.
Jack's Iron Tusk Charge followed, his tusks spinning like drills, Haki crackling as he barreled forward. Missandei conjured Ironwood Wall, a massive Haki-coated tree trunk that cracked under the impact but held, buying her time. She leapt onto the trunk, striking with Vine Lash, Haki-infused tendrils whipping Jack's face, one wrapping his trunk, pulling it taut.
Jack snapped the vines, his Calamity Slam stomping the ground, collapsing the trunk and sending Missandei tumbling, her ribs bruised. She rose, summoning Forest Spire, a towering tree that pierced Jack's side, blood gushing, but his durability kept him standing.
Jack's relentless assaults tested Missandei's stamina, her Haki draining as she wove through his attacks. His Tusk Barrage, a flurry of Haki-charged swings, tore through her Vine Cage, shredding it to splinters.
Missandei dodged, but a tusk grazed her shoulder, tearing flesh, pain searing. She countered with Sylvan Crush, roots erupting to bind Jack's legs, their Haki tips digging into his hide.
Jack broke free, his Mammoth Quake splitting the floor, forcing Missandei to leap onto a pillar. She struck with Thorn Tempest, a storm of Haki-coated thorns that peppered Jack's back, slowing him, though his roars shook the chamber.
Missandei's agility and forest powers kept her a step ahead, but Jack's sheer endurance was overwhelming. He charged with Drought's Wrath, a full-body tackle, his Haki-coated frame like a fortress.
Missandei's Emerald Aegis, a Haki-infused root barrier, cracked under the impact, sending her skidding, blood dripping from her wounds. She noticed Jack's charges grew slightly slower, his hide riddled with cuts.
Baiting another Tusk Drill, she dodged, unleashing Verdant Spear, a massive Haki-charged root that pierced Jack's chest, blood spraying. Jack staggered, roaring, and swung his trunk in Calamity Arc, forcing Missandei to dive, her leg gashed by debris.
Missandei (gritting teeth): "You're a calamity, Jack, but even calamities fall. My forest will outlast your destruction."
Jack (bellowing): "Outlast me? I'm Kaido's wall! You're bleeding, bitch—your forest's burning, and I'll bury you!"
Missandei's edge emerged as Jack's stamina waned, his massive form slowing under her relentless attacks. She unleashed Forest Dominion, the chamber floor erupting with Haki-infused trees, their branches coiling around Jack's limbs, anchoring him.
Jack shattered them with Mammoth Frenzy, a Haki-charged rampage, tusks and trunk flailing, but Missandei dodged. She struck with Ironwood Lance, a Haki-coated root spear that pierced Jack's flank, cracking ribs, his roar shaking the walls.
Jack's Tusk Apocalypse, a final Haki-charged charge, aimed to crush her, his tusks glowing like molten steel.
Missandei met it with Sylvan Judgment, summoning a massive Haki-infused tree that impaled Jack's shoulder, roots burrowing into his hide. He staggered, blood pooling, but swung his trunk in a desperate Calamity Strike.
Missandei, battered and bleeding, channeled her last reserves, unleashing Eternal Grove, a forest of Haki-coated roots and vines that engulfed Jack, binding his limbs, piercing his hide, and squeezing until his mammoth form collapsed, reverting to human, unconscious.
Missandei (collapsing to one knee, panting): "For… Wano… for freedom… you fall."
Missandei, bloodied but unbowed, stood over Jack's fallen form, her victory a testament to her skills. The rebels surged forward, their katanas gleaming with renewed vigor, as the Beasts Pirates faltered, their ranks crumbling under the loss of Jack.
