The ponies and mobians watched as the two Apocalypse magic users fight from their view in the floating island. Some of the mobians had unsure expressions, knowing full well what the Metal Overlord could do. Meanwhile the ponies stared with their mouths open, shocked at Metals transformation. Rainbow and Luna on the other hand stuggled to keep their wings down at the sight, they had come to find themselves attracted to Metal in his base form somehow, so this was kind of a turn on for them.

The group watched as Metal raised his claw-like cannon into the air and created a red shield around the battlefield to avoid collateral damage. "What is that thing?" Applejack asked.

"That's Metal Overlord, a form that Metal Sonic can achieve if he copies enough data." Shadow (our Shadow not Jack) explained with his arms folded. "I suspect he had already gathered enough data awhile before this, he just saw no need to use it."

The group all watched through the red dome as the two beings clashed.

Discord teleported out of the way of a huge beam of red energy that had been shot at him. He warped from spot to spot as Metal tried to blast him. Discord teleported behind Metal and threw a huge fireball at the back of his head.

Metal grunted in pain before he quickly turned around, grabbed Discord in his claw cannon before slamming him into the ground and repeatedly blasting him. As Discord healed himself he shakily got up to see Metal gathering energy and his body being coated in a dark red aura. "CHAOS BLAST!!!"

A huge wave of energy swept Discord off his feet and burned his flesh as the waves of blood red embers flowed over him. As the explosion faded Discord shakily snapped his fingers and his body was healed. He flew up in the air and stared bombarding Metal with huge spheres of compressed magic. Metal but his arms up to block the explosions, lessening the amount of damage he took from each blast.

Discord then flew up to Metal and summoned a giant steel boxing glove, he swung it back before bringing it down on his foe, causing a massive shockwave to ravage the battlefield from the force of impact.

Metal roared and opened his jaw. He lunged forward and caught the unsuspecting Discord in the rows of his large razor sharp teeth. Me then began violently chewing, crushing Discord and stabbing him before spitting him out and driving his claw into his body.

Grunting Discord summoned a swarm of red clouds that shot forks of lightning at Metal. Overwhelmed by the wave of electricity Metal pulled away and formed a shield around himself. Discord kept summoning more and more red clouds until the entire dome was filed with them, all working to destroy the shell around Metal so they could tear him apart.

As the shield was about to break Metal charged up his cannon with Apocalypse magic and chaos energy, creating a large sphere of blood red and green energies. As the shield broke he slammed the sphere into the ground. Time stopped briefly as the point of impact twinkled before creating a huge wave of energy, destroying the clouds and creating a large smoking crater inside the dome which was now cracking from the amount of damage it was taking.

The group looked down at the huge cloud of smoke, the silhouette of Metal Overlord visible as the dust cleared. Metal and Discord were staring each other down, both severally injured and breathing heavily. Discord snapped his fingers and a huge boot tried to stomp Metal, but was destroyed by a blast of his cannon.

Metal aimed one last shot at the injured spirit of chaos who no longer had the strength to heal himself. As the shot charged up Discord growled and tried to summon any object he could, but all that appeared was a tiny cotton candy cloud.

"Goodbye, Discord." With that Meral unleashed the final beam of energy, burning Discord and causing him to fall unconscious in a near death state. As Metal watched Discord slowly fall to the ground he caught his breath and looked up to the group and gave them a thumbs up with his claw. The group cheered and Metal fell into unconsciousness, still in his Metal Overlord form.

Meanwhile

Mephiles looked down at the battle and gave an evil chuckle. "Now that Discord is immobilised, I can take his body as a replacement for Iblis and create Solaris. I can finally fulfill my purpose and bring time itself to an end." Smirking Mephiles teleported down to the unconscious Draconequus and hid from the group that were converging on the limp Metal Overlord.

Mephiles placed his hand on Discords head and pulled out a chaos emerald.

"Now then Discord..." He floated up into the air slightly and began glowing. "... Lets plunge the world into chaos!"

As Metal came to, he opened his large eyes and looked down ta the smiling group that had gathered in front of him. Luna and Rainbow flew up to his eyes and gave warm smiles. "Have I died and gone to heaven, because I see two angels in front of me right now."

Rainbow and Luna couldn't contain their laughter. "Oh my gosh Metal that was the cheesiest thing you've ever said!" Rainbow exclaimed as she held her sides.

"Well then that's the last time I ever give you girls a compliment, that means there's no one to feed your ego Skittles." Rainbow stopped laughing but Luna's only intensified.

"Now now let's not get crazy here."

Metal chuckled and slowly rose from the ground, but kept his head down at a level where the group could talk to him.

Luna calmed down and kissed his forehead. "Regardless of how cheesy that was, it was still really sweet, thank you dear."

Metal gave a soft smile and sighed in relief. "Oh what a crappy few days these have been." He was about to speak when his eyes widened in horror. "Oh fuck, Mephiles!"

He was about to return to normal and fly up to the floating island but turned around as he saw the sky become filled with grey clouds, with Mephiles floating high in the air with all the chaos emeralds around him. As the emeralds glowed a large amount of blood red energy and Discords chaos magic started to converge on the crystal hedgehog. With a blinding light, which Metal shielded then group from with his size, there was now a new creature in the sky, a being that could erase time itself. Solaris.

Metal looked up at the sun god and back to his friends. He sighed and opened a portal to Gales world and pushed them all in. "Sorry guys, but I can't risky you getting hurt." Closing the portal before anyone could get back through he used the master emerald to teleport everyone else in Equestria to Green Hill Zone where they would be safe from the sun god.

The two stared each other down, Metal formed wings and took to the skies. The both let out roars before charging towards each other.
