[BOSS BATTLE: PRINCESS MIDNIGHT SPARKLE]

Seraphic Delta Brony began by sealing up the portals that Midnight Sparkle had created. She tried to counter Delta's movements by ramming into him, but time and time again he dodged. Once he sealed most of the rifts, he took to battling Midnight Sparkle directly. He fired a few magical orbs of energy at her, but she countered with one sweep of her magical beam. She fired her own projectiles at Delta Brony, one of them made impact with him, the others creating dimensional rifts. Delta used his own magical beam to temporarily blind Midnight, while he took to sealing the rest of the dimensional rifts. Eventually, he managed to seal them all.

"You will PAY for this!!!" Midnight cried out as she charged a massive beam of energy.

[BOSS BATTLE: PRINCESS MIDNIGHT SPARKLE PHASE 2]

Delta countered with his own magic beam. Delta Brony and Midnight Sparkle locked their energy beams in a decisive battle for both the human world and Equestria. It became a very swift close call, but eventually Delta managed to deflect Midnight's energy beam back at her, defeating her.

[PRINCESS MIDNIGHT SPARKLE DEFEATED]

Princess Twilight Sparkle is Back to Normal

Princess Midnight Sparkle's energy beam was pushed back at her, along with Seraphic Delta Brony's energy beam. She screamed as the force of the beams impacted her, ultimately resulting in her defeat.

[MISSION ACCOMPLISHED]

Twilight was turned back to normal, and she woke up, feeling weak. "Delta...is that...you?"

Delta Brony laughed in joy. "Twilight, you're OK!!"

Sunset Shimmer, as well as the human Twilight Sparkle, looked on, happy that the world was saved. "He did it, he finally did it!" Sunset said with glee.

"Incredible. That Delta guy was able to use his magic was able to use his magic to turn Twilight back to normal." the human Twilight spoke, almost as if she had a great admiration for Delta Brony.

Princess Twilight got up, as Delta Brony summed up what just happened. "Princess Dark Matter wanted you to take human Twilight's place as Midnight Sparkle. That's why she took her device, so you could wear it."

Twilight was very confused. "What? Princess Dark Matter was behind all this?"

"Yes."

Twilight approached Delta, resting her hand on his shoulder. "Oh Delta, I was so worried because of what she did. Thank you so much, I didn't know it was going to happen. How could I ever repay you?"

The two ponies-turned-humans locked arms together. "We could start by sealing the portal between these two worlds." Delta said as he and Princess Twilight were teleported back to Equestria, and the final rift closed behind them, as the human Twilight waved them goodbye.

"Bye, Delta Brony."

Sunset turned to go back inside the building, with the human Twilight following close behind. "Thank you Delta, for saving our world."

Back in Equestria, all of Twilight's friends were waiting for her return. "I'm back!!" Delta called to the others.

Pinkie Pie immediately noticed Delta had some company. "Look, there's Twilight!"

Princess Twilight Sparkle was glad to be back to normal. "Hey, let's party."

And so, another end to another adventure for Delta Brony and company.
