Interrupted Demon Transformation

Dio's Hamon energy reached the pinnacle in this fight. He even saw the real Mephisto was sitting on his throne in hell through the projection of his Hamon Energy clashing with the Demonic Energy of Mephisto's clone! Dio then used his [Metal Silver Overdrive], and powered up the [Reaper's Gaze] even further!

"Reaper's hunt!" Dio shouted as he dragged the huge scythe forward, cutting everything in his field of vision. The air was heavy as it was filled with a compressed air blade from Dio's scythe, and it even destroyed Mephisto Black Great Sword into pieces!

The compressed air blade even aimed to cut Mephisto's clone into pieces, but Mephisto retreated swiftly before that happened. He knew that some Demon Lord would mock him later for backing off against a human, but it was still better than being mocked on for actually losing to a human!

Seeing that he had no winning condition, Mephisto immediately demonized his arm to create a pair of sharps weapons! A faint sulfuric smell was clear in the air as a towering volcano appeared behind Mephisto. The compressed air blade hit the volcano, and it exploded, sending shockwaves across the Mirror Dimension. Dio was worried for a second as the Mirror Dimension became unstable due to the massive impact of the shockwave.

Dio quickly stabilized the Mirror Dimension with his mental prowess. He knew how to stabilize the dimension thanks to the Ancient One's memories! But still, Dio knew that the shockwave resulted from his attack and Mephisto's demonization was too powerful! Hadn't he used the mirror dimension, entire Hong Kong would be levelled to the ground right now!

When the dust from the shockwave dissipated, Mephisto showed up looking miserable with his fine suit shredded. His demonic arms were also cut off from his body, and the small horns on his head were also cut off! He couldn't believe what just happened as he could say that it was his first time to suffer damage to this extent, even if it was just his clone!

Nevertheless, the clone could still regenerate back to health later. Mephisto looked pissed as now, his weapon was destroyed, and he got beaten up by a mere mortal! Even when he faced the Ancient One in the past, he never sustained this much damage as the Ancient One would try to banish his clone back to hell.

"This clone is too weak! Next time, you won't be so lucky! You will wish you would die sooner as you will die in the most painful way possible the next time we meet!" Mephisto said coldly. "But for now, let's see if you can withstand some of my real power!" Mephisto said as his clone was suddenly covered with a crazy amount of Hell Fire, it wasn't meant to regenerate the clone, but instead, it could transmit Mephisto's real power directly to the clone!

Although the multiverse's rule was applied here, he knew that he would sustain damage to his real body if the clone died, but then again, he wanted to teach this Earthling some lesson for laying his hands on the great Demon Lord! The multiverse law was being weakened by the Dark Dimension's integration to the Earth, so he knew that it was his last chance to summon more power to Earth before the Dark Dimension was expelled from the Earth! If, by any chance, the Dark Dimension successfully integrated fully with Earth, he would lose all the fun to Dormammu!

Mephisto's clone suddenly increased in stature as its height already reached 2.5 meters! The clone itself now wore a red suit instead of black, and the Hellfire that covered him earlier began to twirl as it was absorbed into the clone's body!

. . . . . . . .

"What do you want?" Dormammu said as he glared at the human who dared to enter his dimension. He already killed this human hundreds of times already, but he kept coming back without any sign of stopping!

"Leave the Earth and take your fanatics with you! Stop trying to invade the Earth and never come back! Once you promise me all that, I will break the cycle of time. Otherwise, you and I would be forever stuck here like this!" Stephen said confidently.

Stephen knew that Dormammu's patience was running thin and that he couldn't comprehend the concept of time as this Dark Dimension didn't have one! He knew that Dormammu would be forced to agree here! Sure enough, not long after, Dormammu accepted the condition and took Kaecillus and all his men back to Dark Dimension before leaving the Earth.

Stephen returned and reverted Hong Kong to what it used to look like before Kaecillus' attack. Everything seemed to return to its original appearance. Still, Stephen didn't know what consequences he would bring for breaking the law of time like this! At the same time, he took a look at where Dio was supposed to stand and saw the flicker of the Mirror Dimension was still there, meaning that Dio wasn't done dealing with the demon just yet.

. . . . . . . . .

"What is your name, human?" Mephisto curiously asked as he transformed back to his normal human appearance.

"My name is Monkey D. Luffy, and soon enough, I will become the king of the universe! You better remember this name!" Dio said with a smirk on his face.

"Very good, Monkey D. Luffy! I will remember your name. The next time we meet again, your soul will be mine!" Mephisto said as he began to laugh, and then a strong hellfire emerged around Mephisto's feet.

Dio thought Mephisto was about to run, but he didn't know that Mephisto wanted to blow up the clone itself! He changed his mind to attack the human as he sensed the Dark Dimension was already gone from the Earth, meaning that the Multiverse law has returned to normal!

He knew that the new Sorcerer Supreme would be waiting outside of the Mirror Dimension, so he didn't have anywhere else to run. The only option left was to destroy this clone before it could serve as a link to connect anyone to his real body!

Once Dio noticed that the clone was about to explode, he frowned as he knew the explosion would be huge this time. He activated [The World]'s power and stopped the time as he made his escape. As the time returned to normal, Mephisto's clone already turned to dust, and the area was destroyed, making a huge crater similar to that of a huge missile impact!
