As the two formidable warriors stood facing each other in the middle of a desolate wasteland, the air between them crackled with tension. Luffy cracked his knuckles, a look of determination etched onto his sun-kissed face. Mahito smirked wickedly, his eyes flickering with dark magic. Luffy wasted no time in charging towards Mahito, his body blurring with incredible speed as he utilized his gear 2. Mahito's eyes widened in surprise at Luffy's sudden acceleration, but he quickly composed himself and erected a dark barrier to protect himself. Luffy smashed into the barrier with a powerful blow, but it remained steadfast. You bead of sweat trickled down Luffy's brow as he realized the full extent of Mahito's power. Suddenly, he leapt back and concentrated, closing his eyes as he activated his advanced observation haki. Mahito watched in confusion as Luffy's body flickered and vanished from sight. Suddenly, Luffy reappeared behind Mahito, his fist glowing with a menacing black aura as he utilized his advanced armament haki to bypass Mahito's guard. Mahito cried out in pain as Luffy's fist struck him squarely in the back, sending him hurtling forwards. Luffy wasted no time in chasing after him, his body blurring with incredible speed as he utilized his gear 3 to increase the size of his fists. Mahito turned to face him, a wicked grin playing across his face as he prepared to utilize his soul multiplicity. Suddenly, Luffy cried out and his body began to transform, his arms and legs extending in a grotesque manner as he activated his gear 4 snakeman. Mahito's eyes widened in horror as Luffy's fists slammed into him again and again, changing direction each time with incredible precision. Finally, Mahito crumpled to the ground, unable to withstand Luffy's relentless barrage. As Luffy breathed heavily, his body returning to normal, he looked down at Mahito and chuckled. "Sorry pal, but you were no match for me. Next time, bring something better to the fight." And with that, Luffy turned and walked away, not even bothering to check if Mahito was still alive. For in the world of pirates, only the strong survive.
