Charging at full force against the Celestia duplicate, they ultimately ended up in a struggle. Kicking and clawing away at each other, they fell onto a platform where Discord could watch them. Due to the dark magic that was imbedded within Spike, he had access to a multitude of spells. But even then, the Celestia duplicate was evenly matched against the dragon. The alicorn started firing flame-based magic spells at Spike, but they were impervious due to the fact that he was a dragon and he has leveled up to the point where he can withstand even the strongest attacks.

"Ha! Fluttershy is more of a threat than you!" Spike taunted.

Enraged by that insult, Celestia charged towards Spike and tried stabbing him with her horn. However, he jumped on her back and rode on her. Immediately, he started slashing and clawing away into her body. Seeing this, Discord tried swatting Spike, but but the latter jumped off and the former unfortunately hit the Celestia duplicate. Falling in the sky, Spike struggled to fly at first. His only best was that he could glide while trying to figure out how to kill Discord.

"So what do you plan to do now?" the creature asked.

"I have an idea, but there's gonna be a little risk involved. Would you care to hear?"

"Hmm?"

Spike explained his plan while he continued to run. Whatever he was planning, it needed to work. Otherwise, everything that Spike would work for would be in vain. But he knew that this plan had to work. It had to. As he continued to run, he was suddenly spotted by the Celestia duplicate and she gave chase. She started to shoot more beams of magic at him while he kept running. Just then, he spotted a cliff ahead of him. Knowing he had no other choice, he ran towards it and jumped off it. He started falling down at the speed of sound as Celestia watched in confusion.

"Okay! Let's do this!" Spike shouted as he spread his wings out.

He started flapping them with as much strength as he could to reach the other platform, but only with so much effort as he hadn't grown use to his flying abilities yet. But he knew he was making progress. Seeing this, the Celestia duplicate decided to shoot his wings off if he were to make his way to Discord. Running across platform after platform, the duplicate felt that something was off as she continued to fire at him. Instead of shooting at him this time, she decided to charge him with her horn. Seizing the opportunity, Spike slid off a falling platform and jumped on the next one.

"C'mon, Sunbutt! Is that all you got?" Spike taunted in a sinister voice.

This time, Celestia fired a full blast of magic, attempting to destroy the entire platforms. At the next moment, Spike leaped off the last platform and landed on Celestia. He drove his claws deep into he skin and steered her towards Discord. Immediately, Discord took notice of this and started hurling pillars at the two. Dodging every pillar that was thrown at him, Spike was above Discord and ready to finally kill the treacherous Draconequus. But he knew that the Celestia duplicate was in his way, so he moved his way around her body and started pummeling her. As they fell from the sky, flashbacks were ranging around at random as he remembered the times he was mistreated by the Mane Six and mostly everypony else. The rage and hatred that welled up within him enough to having him headbutt Celestia multiple times as the fell. In a last-ditch effort, Celestia charged a large blast of magic. However, Spike grabbed her horn and broke it off. With the horn in his claws, he stabbed her in the throat with it and she started choking as the blood oozed out of her mouth. In a feeble attempt to get him off, he gouged her eyes out and snapped her neck as they fell, turning her back into the Discord duplicate. Unbeknownst to them, Discord opened his mouth and swallowed them after they fell.

"Oh, what a tasty treat! Shame I will be feeling it in the bathroom!" Discord shouted as he laughed.

Just then, he felt something in his stomach. As if he were having a belly ache, Discord moved his arms to feel how his stomach was doing. Groaning in pain, his stomach was ripped out and Spike was carrying the real Discord who holed up inside the false body. The giant body started to disappear into thin air, leaving Discord with a now angry Spike. Now severely weakened and defenseless, Discord started backing away.

"Listen Spike, I know what I did to you was beyond unreasonable and deplorable, but I was-"

Just then, Spike punched Discord in the nose. The impact was so hard that his nose started to bleed.

"Augh! Okay, so maybe I did deserve that, but listen to yourself. The more you travel down this road, the more-"

Spike then kneed him in the face and proceeded to beat him even further. Because Discord had no more magic left, he was rendered defenseless and had no means of escape. He couldn't even snap his fingers in order to escape. He tried to get away, but the angry Spike grabbed him and started to lay the smackdown on Discord. Using all sorts of moves on the immobile draconequus, Discord was now severely crippled and couldn't escape at all.

"Are you... happy... now?" Discord asked as he coughed up blood.

"Oh, you have no idea what I plan to do with Equestria. When I head to Canterlot, I intend on bringing the end to these ponies you have now come to call your friends. Everypony that you care for and love will suffer the wrath of all those who wronged them and I will see to it that their extinction is imminent." Spike said as he turned his back.

"Who... are... you? You sound nothing like the Spike I knew."

Spike turned around and said,

"I am the Shadow King Bahamut, and you will meet your end."

"What?"

Just then, the creature started to summon something behind Discord. The latter turned around immediately took notice as he turned around. It was a black hole. Knowing the horrors that awaited him, Discord tried crawling away, but the hole's pull was too much to evade.

"No! Y-You can't do this!"

"Oh, but you deserved this. Just like how you let him suffer from obtaining this. I promise that everypony will suffer and everything that you did to him, I will make known."

"Please! You're making a big mistake!" Discord said as he clung unto the ground.

"Really? Because I seem to recall a certain group of ponies who let you out. But don't worry, you won't be around to witness the havoc and chaos I will unleash upon everypony that you love. Especially your beloved Fluttershy."

"What? No! Not her. Anypony but her!"

The pull started to get stronger as Discord started to lose his grip.

"No! No! NO! FLUTTERSHY!!!!!" Discord tearfully shouted as the black hole finally pulled him in.

With that, the battle was over. Spike turned back to the Dragon Badlands to see how Torch was doing.

Meanwhile back at the Crystal Empire, everypony was wondering what to do next as Celestia suddenly started to feel Discord's magic dwindle along with the other alicorns.

"I don't believe it..." Celestia said.

"What in the hay are you talking about, Princess?" a confused Applejack asked.

"Discord... I can't figure out how... but... he's dead." Twilight said.

"WHAT?!" everypony shouted simultaneously.
