Charming Thunder walked up the stairs which led to the roof of the school to see what is going on from above. When he opened the door, a magic blast flashed in front of him. He covered his eyes with his arm as he slowly walked to the edge of the roof. The flash faded away and revealed Sunset Shimmer now with demon wings and teeth sharp as a thorn on a rose. He hid until the moment came to reveal himself to her. "I've had to jump through so many hoops tonight just to get my hands on this crown, and it really should have been mine all along," Sunset growled. "But let's let bygones be bygones. I am your princess now, and you will be loyal... to me!" She then broke the front of the school and the students inside screamed. Sunset calmed things down by using her mind control spell on everyone in the building. She turned to Snips and Snails and ordered, "Round them up and bring them to the portal." She then flew out and confronted Twilight and the others. "Spoiler alert: I was bluffing when I said I was going to destroy the portal. I don't want to rule this pathetic little high school; I want Equestria! And with my own little teenage army behind me, I am going to get it!"
"We meet again, Sunset Shimmer," Charming Thunder said. Sunset Shimmer turned to face the armored figure and laughed.
"Well, well, well. If it isn't my old friend. Charming Thunder."
"Save your welcomes. You are dealing with someone important. Bow before the son of King Sombra."
"The only person who should be bowing is you."
"Kneel!!" Charming Thunder shot lightning out of his finger tips which caused Sunset Shimmer to fall to the ground and forced her to bow. Lightning faded away as Charming Thunder lowered his arm. "Your powers will soon wither away. Soon the crown will be returned to its rightful owner. Yet you struggle to keep it for yourself. And you betrayed me and Celestia."
"I was betrayed by Celestia. She had secrets that she could never tell me about this magic mirror which led me here to this world."
"You know that Celestia would never relinquish her magic." Charming Thunder walked to the edge of the roof and jumped down behind the mind controlled students. "Die or defeat me. Either way, Celestia taught you well. But you still have much to learn." He then activated his lightsaber and readied himself for combat.
"She has nothing left to teach me, old friend." Sunset's eyes glowed and Flash Sentry stepped fort to oppose Charming Thunder. "Deal with him, my minion." A lightsaber hilt levitated off of Charming Thunder's belt and was caught to Flash Sentry's hand. He activated it and jumped to strike the dark figure but his opponent blocked the attack. Charming Thunder then shoved Flash back and backed up a little.
"He may serve you well, Sunset. But his usefulness to you will come to an end." Charming Thunder force pushed Flash through the crowd and jumped to the roof. As Flash got up, Charming Thunder levitated giant rocks and tried to hit him with them. Charming Thunder got angry even more. "I will show you the true mastery of the force but this time the dark side." Flash jumped to the roof and slashed some strikes at him. Charming Thunder blocked the strikes then shoved him back. He then levitated a large metal object and threw it at him. Flash grabbed it and threw it back him but Charming Thunder used the force to throw it aside. Flash then repulsed him to the ground and levitated a giant rocks. He then dropped it on his foe and moved them aside. Charming Thunder's suit is now damaged with cuts on the sleeve and all of his gloves were destroyed in the process. His breathing sound became different as well. When he got up, his cape was damaged as well. He then activated his lightsaber and tried to strike Flash but his opponent blocked his strikes. Flash slashed at his opponents leg and Charming Thunder knelt back to the ground. He blocked the strikes until he got tired. Flash hits his helmet to reveal his face. Charming Thunder had enough so he levitated Flash and slid him on the ground and threw him back to the army. He jumped down in front of the downed Flash Sentry and deactivated his lightsaber.
"That is why I wont let you," Twilight said.
"Oh, please! What exactly do you think you're going to do to stop me? I have magic, and you have nothing!"
"She has us," Rainbow said as she and her friends stood beside Twilight.
"Gee, the gang really is all back together again." Sunset began to charge up a fire ball in her hands as she continued. "Now step aside! Twilight has tried to interfere with my plans one too many times already! She needs to be dealt with!" She threw the fireball at the group and the fireball exploded. She then laughed but when she took a look back, she saw Twilight and her friends being protected by a magic shield. "What!?"
Twilight smiled as she realized something important and said, "The magic contained in my Element was able to unite with those that helped create it!" The crown on Sunset Shimmer's head glowed and fired a magic beam and Twilight and her friends. "Honesty! Kindness! Laughter! Generosity! Loyalty! Magic! Together with a crown, they create a power beyond anything you could imagine, but it is a power you don't have the ability to control! The crown may be upon your head, Sunset Shimmer, but you cannot wield it, because you do not possess the most powerful magic of all: the magic of friendship!" A rainbow beamed towards Sunset and surrounded her. It also came close to Charming Thunder as he tried to hold on. "Here and in Equestria, it is the only magic that can truly unite us all!"
"You have betrayed my aunt and her allies both," Charming Thunder shouted. "You have betrayed me as well. And now, you have doomed your self, Sunset Shimmer." Charming Thunder fired lightning out of his finger tips to keep her still. A tiny beam fired at Flash's head and connected to the other students as they were no longer in control by Sunset Shimmer. The rainbow also hit Snips and snails as they tried to get away. Charming Thunder screamed in rage as a white explosion pushed him away. He then impacts a wall and landed on the ground.
