Summon the Villain: Marvel.

Kang's back suddenly split open, revealing a row of long limbs. These limbs were covered with hard shells like insect limbs, and the end of each limb flashed with sharp light. They stretched out quickly, as if they had their own consciousness, dancing flexibly in the air, ready to launch a fatal attack at any time.

Kang laughed, his laughter was full of madness and distortion, his eyes flashed with lustful light. "Hahahaha! Look at my new toys, Sephiroth!" he said arrogantly, "These limbs are specially prepared for you. You know what? I like to feel the pain and despair of the opponent in battle, just like playing with a helpless woman in bed!"

Kang's words were full of obscure sexual innuendos, and his voice was low and grotesque, as if he was enjoying the morbid pleasure of the moment. "Come on, Sephiroth, let me see your performance, let me see how you struggle in front of me!" Kang's limbs were waving quickly in the air, bringing gusts of wind, and his body quickly rushed towards Sephiroth, attacking with his limbs and rapier at the same time.

Sephiroth's eyes remained calm in the face of Kang's crazy attack. His sword trembled slightly in his hand, flashing with cold light. His movements were elegant and precise, and his body dodged lightly in the air, and each dodge was like a graceful dance.

"Do you have any other skills?" Sephiroth said coldly, with a strong sense of sarcasm in his tone. His sword swung rapidly in the air, and each strike was fatal, hitting Kang's arthropods and rapier accurately.

Kang's limbs danced wildly in the air, trying to entangle Sephiroth's body, but each time they were easily resolved by Sephiroth's sword. Kang's laughter became more and more crazy, and his attacks became more fierce, but he could not break through Sephiroth's defense.

"I'm tired of it." Sephiroth said calmly, the sword flashing coldly in his hand, and every swing of his sword was elegant and cold.

Kang's face was covered with an arrogant smile, his eyes were full of madness and distortion, as if he was enjoying the morbid pleasure of this moment. His body kept twitching, his hands were waving wildly in the air, and his limbs were dancing wildly behind him, causing gusts of wind.

"Hahahaha! Let me show you my other abilities!" Kang laughed wildly, his voice so sharp and piercing that it seemed to penetrate a person's soul. His eyes flashed with a cold light, and a twisted smile appeared at the corner of his mouth.

Kang's body suddenly became distorted, his skin began to become transparent, and the complex mechanical structure inside could be seen. His limbs grew wildly, becoming more pointed and sharp, and each limb was covered with venom, emitting a disgusting smell. His hands became as sharp as claws, and his fingertips flashed with cold light.

"Look at this, it's specially prepared for you!" Kang growled, his voice full of morbid excitement. His body moved quickly in the air, and his limbs and claws attacked simultaneously with deadly force and endless venom.

Kang's attack was swift and fierce, his limbs left afterimages in the air, accompanied by the sound of tearing the air. Each of his attacks was accompanied by a morbid pleasure, as if he was enjoying the other's pain. His laughter became more and more crazy, and his eyes flashed with endless fanaticism.

Sephiroth finally felt the pressure, his eyes became sharper, his body dodged flexibly in the air, and every movement was like an elegant dance. He swung his sword quickly in his hand, bringing out cold light, trying to block Kang's attack.

"Finally, it's getting interesting." Sephiroth said coldly, with a hint of disdain and vigilance in his tone. His movements became faster, and every time he swung the sword, it brought strong wind pressure, trying to suppress Kang's crazy attack.

Kang's crazy attack was like a storm, his limbs and claws kept waving in the air, with sharp wind sounds and deadly venom. Each blow was swift and deadly, as if to tear Sephiroth into pieces. His body moved quickly in the air, his limbs swept towards Sephiroth like a whip, and his claws kept stabbing out, trying to find Sephiroth's flaws.

Kang's laughter was high-pitched and piercing, as if he was enjoying this bloody game. His eyes flashed with madness, and his whole body was filled with morbid power as if possessed by a demon.

"Hahaha! Try this!" Kang growled, his voice filled with endless morbid excitement. He waved his hand suddenly, and a stream of black venom shot out from the tip of his claws, heading straight for Sephiroth. The venom turned into a black lightning in the air, carrying a pungent fishy smell, as if it could corrode everything.

Sephiroth dodged quickly, his body sliding in the air like a ghost, and the sword in his hand swung quickly, bringing with it a series of cold lights. The venom brushed against the corners of his clothes and corroded the ground, making a "sizzling" sound, and a pungent smell filled the air.

Kang was not satisfied with this. He waved his limbs wildly, with sharp edges and deadly power. His body spun in the air, and his claws kept stabbing out, as if he wanted to crush Sephiroth completely. His attack speed was extremely fast, as if he didn't give Sephiroth any chance to breathe.

Sephiroth calmly faced Kang's crazy attack, his body flexibly dodging in the air, every movement like an elegant dance. His eyes were calm and sharp, the sword in his hand flashed with cold light, and every swing brought deadly power.

"Your attack is disorganized." The sword swung quickly in his hand, bringing up sharp wind blades that hit Kang's limbs and claws directly.

Kang's limbs were cut off by Sephiroth's sword, making a sharp cracking sound. Kang's body shook violently, but his laughter was still high and crazy, and his eyes flashed with a cold light, as if the battle had just begun.

"It feels so good!" Kang laughed shrilly, his voice full of climax and morbid excitement. His body rushed towards Sephiroth again, and his limbs and claws attacked at the same time, with violent power and deadly venom.

"Your madness can only lead you to destruction." Sephiroth's sword drew a graceful arc in the air and hit Kang's heart directly.

Kang's laughter stopped abruptly, and a flash of fear flashed in his eyes, but was soon replaced by a stronger frenzy. His limbs swung wildly, trying to block Sephiroth's attack, but the speed of the sword was too fast for him to react.

"It's over." Sephiroth whispered, and the sword pierced Kang's heart with a sharp sound of wind.

Kang's body shook violently, his eyes widened, and an expression of disbelief appeared on his face. His limbs and claws hung limply in the air, and his entire body lost all strength in an instant. His laughter gradually became weaker, and the light in his eyes gradually dissipated.

"Haha...ha..." Kang's laughter became intermittent, and his voice revealed deep despair and unwillingness.

Sephiroth watched Kang's body fall down coldly, and shook the sword in his hand slightly to shake off the blood on the blade. His eyes were still calm, as if he had just fought an ordinary battle.

"You are nothing but a pathetic lunatic," Sephiroth whispered.

“Hehe…haha…”

Kang appeared in front of Sephiroth again, his laughter was sharp and piercing, as if he was mocking the whole world. His movements were exaggerated and funny, like a crazy clown, his body spinning and dancing in the air, as if he was performing an absurd dance. Every step was accompanied by a weird rhythm, and the expression on his face was unpredictable, sometimes ecstasy, sometimes twisted pain.

"Sephiroth, do you think this is the end?" Kang's voice was full of madness and teasing, and his eyes flashed with an indescribable light, as if he was enjoying the chaos and destruction at this moment. "Do you know who I am? I am the traveler of the endless world, the master of fear and chaos!"

Kang's fingers moved in the air, as if sketching some mysterious symbols. His laughter was like the cry of a night owl, piercing the silence in the air. His body kept twisting, as if he had no bones, and every movement carried a strange power.

"Do you want to know my origins? Haha, I came from endless darkness, born from countless broken worlds." Kang's voice was low and mysterious, as if it had some kind of bewitching power. "My interest is not just in fighting. I like to admire, to admire the opponent's struggle in despair. That kind of pain, that kind of helplessness, is simply the most beautiful music in the world."

Kang's expression became more manic, his eyes flashing with morbid pleasure. His voice was low and full of temptation, as if he was telling a long and obscure history. "You know, Sephiroth, I am optimistic about you. Your strength, your elegance, and your coldness all fascinate me. I hope that you can become a special toy of mine, one that will never make me feel bored."

Kang's laughter rang out again, with an indescribable pleasure. His body spun in the air, his hands dancing, as if summoning some dark power. The limbs behind him danced wildly, each limb flashing a deadly light.

"You think you can kill me? Hahahaha, you are too naive." Kang's voice was full of contempt and mockery. "I am an immortal being, an eternal being. You can cut off my limbs, you can pierce my heart, but I will always come back, again and again, until you are completely desperate."

Kang's body twisted in the air, as if it had no substance. Every movement he made carried an indescribable strange power, as if he was showing Sephiroth his immortality. His laughter echoed in the air, carrying endless sarcasm and arrogance.

"I will be your eternal nightmare, Sephiroth. No matter where you go, I will be behind you, waiting, watching you struggle in despair." Kang's voice was low and full of bewitching, as if telling an unknown prophecy.

Sephiroth stared at Kang in front of him coldly, with a hint of disdain in his eyes. His sword flashed coldly in his hand, as if responding to his master's fighting spirit. Facing Kang's madness and weirdness, Sephiroth still remained calm and elegant.

"Really?" Sephiroth responded coldly, his voice low and powerful, as if an invisible sense of oppression was looming over Kang.

"Do you think your ridiculous immortality can scare me?" Sephiroth continued, his tone full of contempt and disdain. "No matter where you come from, no matter how many times you have the chance to revive, it can't change the fact that you are nothing more than a crazy clown, a meaningless existence."

His eyes were cold and firm, as if they penetrated Kang's soul and struck the fear deep in his heart. "I have faced countless powerful enemies and seen too much despair and death, but there has never been a moment when my will will waver." Sephiroth swung the sword lightly, and the blade drew an elegant arc in the air, flashing a deadly light.

"What you call eternity is nothing but repeated failures." Sephiroth leaned forward slightly, his body emitting a strong fighting spirit in the air, "And every blow I strike will be your eternal pain. I will make you understand that even the immortal body has unbearable despair."

His voice was firm and cold, like a sharp blade, pointing directly into Kang's heart. "Come on, Kang, let's see how long your so-called eternity can last under my knife."
