After Princess Luna turn into Nightmare Moon once again, every ponies show total horror in their eyes, including her mutilate sister. Monster X, on the other hand, shows delight. He whisper to himself, “All acquiring to plan.” Then, he slowly walks toward the nightmare and shouted, “Nightmare Moon!! I am Monster X!! Join me and we will bring destruction upon this worthless world!!”

The dark princess grinned about his offer. Then, she shouts, “Monster X! Your proposal has to be… DENY!!” She blasted him up against a wall. She landed next to her sister and yelled, “You had harmed me and my powerless sister!! You shall not stand in my way!! For that, I SENTENCE YOU… DEATH!!” Finally, she fires upon the devilish alicorn and finish him off. After eliminating the invader, everyone were speechless for a while. She roared, “NOW, TO BRING DARKNESS TO EQUESTRIA FOREVER!!!”

Now, everyone is in total fear. Except for Pinkie Pie and Loony Turtle as they cheered. They both jump around and shouted with joy, “YAY!!! Princess Luna destroyed Monster X!!”

Rainbow Dash head bung them and yelled, “HELLO!! Now, we got one more problem, Nightmare Moon!”

They both look at each other and spoke, “We mean booo.”

The corrupted alicorn spotted the others and began firing upon them. The others quickly took cover and spotted Twilight is still alive. Applejack rushes toward her friend and said, “Twi, are ya alright?”

The young princess got up, ignoring the scratch wounds, and answered, “I’m fine.”

Sunset Shimmer spoke up, “Twilight, how are we going to stop Princess Luna?”

“I… I don’t know. If only we have the elements of harmony, then we could turn her back to normal.”

“Then, what are we going to do?”

Princess Cadance spoke up, “I know what are we going to do. Me and Shining Armor will distract Nightmare Moon. While the rest of you take my mother to safety.”

Twilight interrupts and demanded, “I’m going to with you.”

Shining Armor look at his wife and she spoke, “Twilight it's too dangerous. What happen-”

“I know it’s dangerous, but you two can’t handle her alone. With two alicorns, she won’t stand a chance.”

The princess of love was thinking and finally answered, “Alright, you can help.”

She turns back to her friends and Rarity spoke, “Be careful, darling.”

She responded, “I will. Just take care of Princess Celestia.” Her friends nodded and they finally move out.

Twilight and her step sister lift off into the air and head toward the corrupted princess and start attacking her. While they were blasting her, Nightmare Moon began firing back, but Shining Armor form shields around his sister and wife. The evil alicorn spotted the guard and ready to fire, but Cadance tackle her aunt. After she attack Nightmare Moon, she holds her down while the others escort Celestia to safety.

Suddenly, the wicked alicorn knock her niece off of her and blast down Twilight. After seeing his baby sister got shot, Shining Armor charge toward the nightmare, until she blasted him out of the way. Princess Cadance attack his aunt again, but the evil princess shocked and throw her toward the wall. When Twilight finally got up, she was in horror when she spotted her sister and brother been torture.

After she was finished harming Cadance and Shining Armor, she turned to the young princess and spoke, "Tell me young princess, are you prepared to die?"

Twilight stands tall and respond, "No. But I'm going to stop you Luna." Then suddenly, the corrupted princess roared in anger and begins charging toward the princess. Twilight also charges toward Luna as well.

Meanwhile, Sunset Shimmer and the others manage to take the injured princess to safety. Then suddenly, she heard a blast from the battlefield and believe that Twilight needed reinforcements. She shouted, "Twilight is in trouble! We need to help her!"

Applejack spoke up, "But sugarcube we're no match against Nightmare Moon. We're not even alicorns to even the odds."

Until, Pinkie Pie interrupted, "But we could buy Twilight and the other more time to regain their strengths for a another rematch!!"

Then, Rarity said, "You know you're right, darling. We could give Twilight enough time to heal and fight again."

Rainbow Dash step forward and spoke bravely, "Alright then... Lets do this."

She began to move out, until Sunset block her and said, "Rainbow Dash you can't come with us. You're no conditions to face Nightmare Moon. Plus, we need you to stay behind and protect the princess."

The wounded pegasus shouted with rage, "WHAT!! You guys need me out there!! You'll need all the help to-"

"Please Rainbow Dash," Princess Celestia interrupted. She can only speak in a for a little while due to her injuries against Monster X. "Please... Let the others handle my sister. I need a loyal protector by my side. I need you... Rainbow Dash." Then, the injured princess went into unconsciousness.

After Celestia was passed out, the rainbow maned pegasus rushes toward her ruler. Finally, she tells the others, "Okay. I stay with the princess. Just take care of Twilight for me."

Sunset Shimmer nodded and turn her attention toward the others, "Alright girls lets go and save Twilight."

Nightmare Moon kept battling against the young princess, but Twilight is beginning to grow weaker by the minute. She's trying to keep her strengths up, but Luna is showing no signs of mercy towards the young princess. Finally, the evil alicorn tossed Twilight aside and laughed. "Poor little pony. You never stand a chance against me. Surrender and I may show you mercy."

However, the young princess began to rise up slowly and respond, "I will never betray Celestia, my sister, my brother, and my friends. I will stand for them and all of Equestria!!"

The evil princess began to laugh and roared, "Then fall before me!!"

The corrupted princess was about to eliminate the princess, until her faithful friends knock Nightmare Moon to the ground. Twilight was surprised by the presence of her friends and yelled, "Girls, I thought I told you guys to defend Princess Celestia!"

Sunset set her hoof on the wounded princess shoulder and responded, "Don't worry Rainbow Dash stay behind and protect her. Plus, you can't handle Nightmare Moon alone."

"Oh yes. We couldn't bare seeing you get hurt by anyone, Twilight," whispered Fluttershy.

"That's right, Twi. We will never abandon y'all, no matter what," Applejack spoke up.

"Oh yes, darling," Rarity spoke. "We will always be with."

Then, Pinkie Pie pops up and shouted, "YEAH!! We're family, Twilight. And families always stand together!!" Tears are developing in the young princess eyes and began hugging them. Finally, all of them form a family hug.

Sadly, the moment ended when the evil voice occurred, "How touching, but that will not save!! Hahahahaha!!" Nightmare Moon had risen again and began firing upon the mare friends, plus Spike and the colt unicorn.

The dumb unicorn spoke, "Maybe we should watch that evil lady before she got back up and attack us."

Spike grabbed and shaken the idiot colt, then yelled, "You think!!!"

Then, the ponies ready themselves for battle. All except for Fluttershy, Spike, and Loony Turtle, which they are hidden cover from the fight. As the five of the mares are ready for battle, Pinkie Pie brings out her party cannon. "Wait a second, I thought that cannon of yours was destroyed there," Applejack questioned the goofy pony.

The pink pony responded, "I kept a spare just in case." Finally, the young brave ponies charges into battle.

As the ponies charges toward the evil princess, Nightmare Moon resumed firing at them. While the three unicorns distracted the corrupted alicorn, Applejack manages to tie the rope around her horn and pulled the princess with it, causing her to misfire. Then, Pinkie Pie fired her party cannon at Luna, buying Applejack enough time to tie her up. Then suddenly, Nightmare Moon broke free then throw the cowgirl toward the party pony. Twilight and the others fire upon the evil princess, but she teleported behind them and blast them away.

Then, the wicked princess spotted Fluttershy and the other two hiding from the battle. She levitated the structure that covering them away, then dash in for the kill. Until, her attack was prevented when a shield thrown towards and hit her. They turn around and spotted the earth guard back to his normal form. He spotted his dummy friend and yelled, "Thanks for turning me back to normal!!"

The green unicorn laugh and said, "Oh ha buddy. How you been?" While they were arguing, Fluttershy and Spike were on the sideline, both felt completely confused.

"Oh, I was fine, UNTIL YOU TURN ME INTO A TORTOISE!!"

Then, Spike cut in, "Hold up, how did you turn back to normal?"

Sword Light answered, "Well, luckily the spell wear off like about forty minutes or so. And I never want to turn back into a tortoise again." After he answered, Nightmare Moon manages to get up and attack the helpless victims. When her blast nearly hit the guard, he screamed and shake his best friend, "Turn me back into a tortoise!! Turn me back into a tortoise!!" Then, they began running away from the horrifying princess.

While the evil princess were chasing them, Twilight hurry and aided her brother and sister. "Shining Armor!! Cadance!! Are you both alright," cried the young princess.

The princess of love rose up and spoke loving, "We're fine, Twilight. What about our mother?"

"Don't worry, Rainbow Dash is guarding her."

Unfortunately, their conversation was ended when Nightmare Moon has returned and began terrorizing the innocent ponies. As they were taking cover, Shining Armor tell the others about his plan. "In order to contain Princess Luna, we need to make her stay in one position so we can drain her power." He pointed at Sunset and Rarity. "You two are with to trap her while Twilight and Cadance are draining her power."

Sunset Shimmer cut in, "That show great sir, but we need someone to distract her."

Rarity agreed, "She's right, darling. Applejack and Pinkie Pie are still wounded from Luna attack." The five ponies can't figure out about who will do all of the distractions.

Loony Turtle was listening to their plan and he assists in helping them by pushing his best friend into the open. After he pushes Sword Light, he shouted, "Ha, Nightmare Duke!! Come and get me!!"

The red guard through a ragged look toward his friend and whispered, "Loony, if there a chance I survive out of this, I will kill you." After Nightmare Moon began firing, the earth pony ran like the dickens.

As Twilight and the others were watching the frighten guard distracting the terrible princess, they quickly spring into action. As Sword Light was running for his dear life, he accidentally trips to the ground. Then, as Nightmare Moon stood before the paralyzed guard, he quickly gets down on his knees and beg for mercy. The wicked princess laughs and was going to kill him, until she was trapped in a force shield by three unicorns. Finally, the two alicorns step in and began draining her power.

As Nightmare Moon kept continuing to attack her way out of the shield, she could feel her energy is growing weaker. Finally, she discovered what they were doing and roared, "You fore mortals!! You will never imprison NIGHTMARE MOON!!!" Then, she released a massive amount of blast. They others try to form the shield with everything they got, but the shield beginning to crack. Even the two princesses aided them, but it still won't matter. Finally, the shield has broken and an explosion occurred.

After the smoke finally faded, every pony was completely knocked out from the blast, but luckily no one got killed. When Twilight awakens, she found herself next to Sunset and were happy seeing her friends are alive. Until, she spotted someone with Nightmare Moon. It's Monster X! Somehow he survived Luna blast earlier. She doesn't understand why is he holding Nightmare Moon in his arms. Then suddenly, he kisses her.

Pinkie Pie pop behind the young princess and whined, "Ewwww!! He's kissing her!!"

When Sunset Shimmer awake, she noticed something wrong between them. Finally, she cried, "Twilight!! Look what's happening!!" Then, she examined closely, she noticed that the alien alicorn isn't kissing Luna, he's sucking out her nightmare.

After the venomous Monster X sucks all of the nightmare, he shoved Luna aside and shouted, "Finally!! I have gathered enough energy to destroy this foolish world, ONCE AND FOR ALL!!" Then, he begins to change form.

As the devilish alicorn were changing, Sunset cried to Twilight, "What's happening to him?"

There is a complete horror in the young princess eyes and answered, "Monster X and Nightmare... they're fusing... together! They're being as one!"

Monster X body was beginning to change. His mane tail was dissolve and form two tails. Then, his horn expand about three feet long. Dark red flame was form as his hair. His shoulders formed into two mini monster heads. His wings turn into dragon wings as well. Finally, he turned into his true immortal form. Then, Pinkie whispered from behind, "Nightmare X."
