Chapter 1: The Meet
It was a clear, starry night in Ponyville and everypony grew tired. Twilight Sparkle and her companion, Spike, were in bed and so were the main six, Rainbow Dash, Fluttershy, Pinkie Pie, Applejack, and Rarity. But everypony didn't know someone who ruled an empire was coming back.
Prince Shining Armor was on the balcony of his and his wife, the Crystal Princess Cadence, balcony thinking about the sinister pony who once ruled the Crystal Empire, King Sombra. Shining Armor still felt like he wasn't gone forever. "I know you're still out there, Sombra," he said with a little anger. "and if you come back, we'll be ready for it."
"Shining Armor?" a familiar voice asked nervously.
"Cadence?" he replied.
"Are you alright? You look like you are about to face a war!" she said with a little more nervous voice.
"I'm fine. I'm just...thinking about something,"
"About what?"
"Nothing, just forget it. Let's get some rest," Shining Armor said tiredly.
One clear, starry night, the one ghost halfa teen named Danny Phantom flew in his bedroom window and morphed into his human form and leaped into his bed. "Man, what a tiring ghost fight against Skulker. Good thing it's over with," he said with weary.
The next morning, Danny's only sister Jazz woke him up saying, "Wake up, Danny! You've got to see this!"
"Alright, just let me get dressed," he said weakly.
"Okay, but hurry up!" she said.
Danny came downstairs with his everyday clothes. A white shirt with a red spot on it and blue jeans with red and white shoes. Danny gasped when he saw a filly laying on the chair in the living room. This filly had fire hair like Danny's alternate self, but it was purple with a lighter purple further in and same thing with the tail. The filly also had a grey body with a mark on its hip. The mark was a little flame the same color as its hair.
"What in the world?! What kind of a pony is that?!" Danny exclaimed.
"Uh, I believe it's a filly," Jazz said with annoyance.
"I can see that. Just-why is its hair like that? And why is its body color grey and why does it have a mark on its hip?" he said.
The filly started to groan and then opened her eyes. She quickly looked up at Jazz, Danny and his parents. She cringed a little when she saw them, but calmed down afterwards.
Jazz patted her on the head as she said, "Ssh, its okay, little filly. There's no need to be scared. We're not going to hurt you,"
The filly looked up at her as she asked, "Are..Are you sure you're not going to hurt me?"
Everyone gasped after hearing the pony speak. How in the world can an animal talk?! That's what everyone in the room was thinking.
"How-how can you talk?!'' Jazz asked curiously.
The filly sighed as she introduced herself. "First, my name is Aron. I come from a world with only ponies there. There are three kinds of ponies there. There are pegasi, earth ponies, and unicorns there,"
"Are there humans there?" Jazz interrupted.
"No. There are no humans there. Just ponies. As I was saying," Aron continued, "There are four alicorns there. They are Princess Celestia, Princess Luna, and Princess Twilight Sparkle,"
"Who's the other alicorn?" Danny suddenly asked at the steps.
"Me," Aron answered as she showed them her tiny horn and tiny wings.
"Is there more?" Jazz asked.
"Yes, but I don't want to waste time. Everypony in Equestria must be worried about me since I am Twilight's sister," she said proudly.
"Every'pony'? Seriously? Why couldn't you just say 'everybody'?" Danny asked with annoyance.
"Because we're not humans, we're ponies. But I won't say it here in this world," Aron answered him.
Danny's dad, Jack, looked at the clock and saw that he should work on his inventions for fighting ghosts. "Well, Maddie, we have to get back to work. The kids can take care of this filly!" he exclaimed.
Danny's mom, Maddie, said while walking down to the lab, "Well, I suppose so. Take care of her, Danny and Jazz!"
"Sure thing, mom! I'll take good care of her!" Jazz exclaimed as she picked up the filly.
Throughout that moment, they didn't know they were being watched.
"Alicron, hmm? That's useful," Plasmius said as an evil laugh followed after when he flew off to his castle in Wisconsin.
"Princess Cadence! Shining Armor! We came as fast as we could!" Twilight exclaimed as she and the main six ran in.
"I wonder what the problem is this time," Rainbow Dash wondered.
"Ooh! Maybe it's a party!" Pinkie Pie blurted out.
"It didn't sound like it when Twilight read the letter Cadence sent us," Applejack said with a little worry.
"Everypony, listen to me," Cadence started. "if you all remember King Sombra, he has returned."
Everypony gasped when hearing the news. Impossible! How can that pony be back if the power of the crystal ponies finished him off?!
"How-how is this possible?! We destroyed him!" Rainbow yelled out.
"Yes, you have. But the crystal ponies magic weren't as powerful when they powered the Crystal Heart. It seems that is dark magic was too powerful to have him be gone forever,"
Shining Armor said.
"Where is he now," Twilight demanded.
"We're not sure, but he's out there somewhere and we need Cadence to put up a shield so he won't get in," he said as he looked a Cadence who was sitting on the throne beside him.
Cadence looked up at him with worry. She doesn't want to go through all that protecting thing again! She knows someday she'll get too tired to hold it up any longer and her magic will just die out until she gets some rest! She knows she wouldn't make it.
"That's not going to work, dear," she said sadly to him. "remember when we did that last time he was trying to break in? My magic died out and I couldn't protect any of the crystal ponies here. You know that!"
Shining Armor just stared at her and sighed. Then he looked back to the main six and demanded, "I need you all to find a more powerful way to stop him and to banish him for good,"
"We'll do as you wish," Twilight said as she and the main six ran out after her.
"Be careful out there," Cadence said with worry.
Aron was standing on the rooftop of the Fentons' home as she was thinking she was being watched while having that conversation with the Fentons.
"I hope that person wasn't thinking of having me as his or her apprentice or something," she said with worry.
"Actually, you're wrong. I do want you on my side,"
Aron was looking around cautiously to find out where that voice was coming from and who it belonged to. "Who are you?! Where are you?!" she exclaimed.
Aron gasped as she saw a ghost with blue skin, a black and white jumpsuit which is mostly white, a cape that's red underneath and white on the other side, and he had blood red eyes and fangs.
"Who are you?! And what do you want with me?!" Aron asked him with anger.
"Hey, relax. I just want to talk. Then, you will be on my side," he said as he smirked.
"I said, who are you?!" she said while getting angrier by the second.
"I am Danny Phantom's arch enemy, Vlad Plasmius. I always try to get him on my side, but he keeps refusing. But, since I was spying on you and the Fentons, I learned all about your little pony world. So, I think you're good enough on my side," he answered.
Aron blinked in surprise. She was just a filly! Why would he want her if she was too young? Aron then frowned at remembering what the older hybrid just said. She didn't want to be with a creep like that! She'd rather be with people who would understand her!
"Yeah, well, I rather be with these people! They don't look as harsh as you! So leave me alone before I grab a chainsaw, rip out your heart and rip it to pieces!" she said as she sounded a bit cruel.
Plasmius cringed a little when he just heard the filly's statement if he didn't leave her alone. But that just made him smirk once more. Having a cruel pony on his side would be even better. "Ghosts don't have hearts. They have cores," Plasmius corrected her.
"Whatever! I don't care! Just leave before I rip your core out with a chainsaw!" Aron exclaimed.
Aron tried to run away until she felt Plasmius' hand grab her fire tail and gave her a dirty look.
"I don't have time for your little games, horse! You either join me or I'll rip your heart out with my claws!" he growled.
Aron just looked at him with fear in her eyes. She couldn't decide whether or not to join Vlad or to just stay away from him!
"DANNY! HELP ME!" Aron yelled as Vlad pulled her closer to him to cover her mouth to keep her from calling Danny.
Vlad finally got Aron close to her and covered her mouth. "I don't care if you want to join me or not! You will join me!" he said as he tightened his hold on the little filly.
In the living room, Danny jolted when he heard Aron yell his name out really loud. Danny then jumped out of his chair and morphed into his ghost form. He didn't hear any more calling or screaming from the rooftop, but he phased through the ceilings and to the rooftop.
Danny gasped when he saw Vlad just starting to fly away with Aron.
"Let her go, Plasmius!" Danny yelled out to him when he sprinted over to him.
Vlad quickly got out of the way before the boy could sprint over and hit him so he would let go of Aron.
"Sorry, Daniel! Since you won't join me, then I'll just have to take this filly!" Plasmius said as he shot a pink ghost ray at Danny. The attack missed by an inch over Danny's head then he charged over to Vlad.
Just as he did, the Fright Knight and his horse landed right in front of him.
Danny was startled when that happened. Just then, Vlad quietly escaped with Aron so Danny wouldn't notice.
But Danny did noticed. He ignored the Fright Knight and quickly charged over to Vlad and shot him with his ghost rays.
But the Fright Knight and his horse flew over to the fight and shot Danny with one of his ghost rays from his soul shredder-or green ecto-sword-and Danny started plummeting to the ground.
But the Fright Knight caught him by the back of his jumpsuit with his sword before he fell to the ground.
"DANNY!" Aron screamed as she struggled to get out of Vlad's hold.
But Vlad wouldn't let go. He was also confused when he saw the Fright Knight. Why was he here? Was he working for Pariah Dark again? How could he if he was locked back into his keep for forever sleep?
Vlad shot Fright Knight in the chest causing him to let go of Danny and falling off his horse. His horse then flew over to him to keep him from falling to the ground. Vlad then grabbed Danny by the neck-but not too tight-and flew away. "I'll have both of them join me, then," he said as he flew the direction to his castle.
Twilight and the main six ran to the Crystal Heart and Twilight used her magic to put a shield around it and only the main six and other good ponies can go through it. Afterwards, they all ran to the edge of the Crystal Empire to see any dark clouds coming towards them.
"I don't see anything. Are they sure he's coming back?" Applejack asked Twilight.
"I don't know, but we're going to check just in case," Twilight answered.
"Uhh, guys?" Fluttershy asked quietly. "I think I see something over there. Do you think that's him?"
But no pony heard her.
"What was that, Fluttershy?" Rarity asked.
"Look over there," Fluttershy said to her.
Rarity and the others gasped when they saw some dark clouds coming towards them. Then a face started coming out of the darkness.
It was King Sombra.
"IT'S KING SOMBRA!" Pinkie Pie screamed.
"Pinkie Pie, calm down. All we have to do is fight back!" Rainbow Dash exclaimed while slamming her hooves together. She then quickly flew over to the darks clouds and tried to hit Sombra in the face.
King Sombra moved out of the way so he wouldn't get hit. Rainbow then flew too fast into the darkness. "RAINBOW!" the main six screamed. Rainbow Dash came out with the edge of her feathers pointy and with some red on them, and had some of that dark purple hue coming from her eyes and her eyes were black and her pupils were green lizard like pupils.
She was possessed.
"Rainbow, NO!" Twilight screamed again.
"I'm with King Sombra, now. All Crystal Ponies, bow down to King Sombra," Rainbow said in a monotonous voice.
"We have to get Rainbow back if we have to beat him!" Pinkie exclaimed.
"We don't have the Elements of Harmony, remember? We put them in the Tree of Harmony!" Applejack blurted out in her face as Pinkie Pie backed away a little. "Okay, but we should still get her back!" Pinkie cried out.
"Let's get all the crystal ponies in the Empire and have them power up the Crystal Heart to keep him away for a while so we could prepare some more and see if we can save Rainbow Dash," Twilight demanded.
"Got it!" everyone declared.
The main six-except Rainbow Dash-ran to every crystal pony to tell them that they need to power the Crystal heart immediately. All the crystal ponies then ran to the Crystal Castle quickly and powered up the Crystal Heart.
All the roads in the Empire lit up with blue neon light and caused all this light to explode and knock King Sombra away and to have all the darkness from Rainbow Dash escape. "Yes! I'm free!" she cried out as she flew over to the castle.
As King Sombra was knocked back, he turned to his regular sized self and went through a green portal that appeared. The portal takes you to a place that is full of these creature that can be invisible.
The Ghost Zone.
King Sombra landed on a nearby floating island face first. "I may not be gone forever, but I don't even know where I am!" Sombra yelled in anger. He paced until he saw a red, wicked castle that was floating on a near island. "Hmm, I wonder who rules this place," Sombra pondered. He jumped on some close by rocks that were floating like a path to the red castle on the floating island.
He then landed on the edge of the island and walked in. Just as he took a few steps in, the walls were closing in. He tried to teleport with his dark magic, but it wouldn't work. He then tried to run through the trap so he could see what was on the other side. but he walls were too fast. "Looks like I will be gone forever," he whispered sadly. However, when the walls closed in, he wasn't crushed. "What in the world?!" he exclaimed. He started walking forward and he phased through the walls. "Strange," he said as he continued forward.
He came down a hallway and then to some two huge doors. He opened them and saw a keep with a green keyhole in the middle. He walked up to it and found a green key with a skull on one end with red eyes. He picked it up, put it in the keyhole and twisted it. The huge door opened slowly and revealed a ghost that a green crown with fire on it and was wearing a green ring with the same skull on it as the skull on the key.
It was King Pariah Dark.
"Who dares to free me?" he ordered.
"Do you rule this place," a voice came.
Pariah looked down and saw King Sombra standing there looking up at him as Pariah smirked a little.
"What, are you going to laugh just because I'm a pony," Sombra asked angrily.
Pariah just looked back up and walked passed him as he said, "No, since you let me out and now I can rule both the human and ghost world,"
"I will help you rule those worlds I you help me rul not just the Crystal Empire, but Equestria," Sombra suggested.
Pariah looked at him as he stated his suggestion. "Equestria? What kind of a place is that?" he asked confused.
Pariah explained to him about Equestria and the two alicorns ruled it.
"I see. Well, doesn't sound too hard. I accept your request." Pariah said as the two rulers nodded in agreement.
Plasmius landed in one of his guest rooms and placed the unconscious teen on the bed and placed the unconscious filly on top of him as he phased through the floor and into his secret lab.
Danny slowly opened his eyes then gasped as he noticed he wasn't in his room or house. Then he noticed that he was in human form and that Aron was laying on him, unconscious. He slowly moved his hand through her purple fire hair as he continually rubbed her on the head.
Aron slowly opened her eyes as she noticed she was lying on Danny and he was petting her on her head. "Danny, what h-happened? A-and where are? Last time I remembered where we were, we were at your house,"
Danny just looked at her as he continued to stroke his hand through her fire hair. "I don't know, I think we're in Vlad's castle," he replied.
Aron looked at him with wide, purple eyes. "I think we should get out of here. He is your arch-enemy after all," she said as she tried to fly.
Aron fluttered her wings as hard as she could, but then fell to the floor. "Looks like no pony taught me how to fly or use magic," she said as she sighed when trying to get up, but she was too weak to even walk.
Danny was still strong enough to walk and stand, but not strong enough to morph. Danny got out of bed, picked up Aron and put her on the bed. "Maybe we can find someone, or somepony, to at least to teach you how to fly," he said as he pat her on the head. "now let's see if we can escape out the window."
Danny then picked up the filly again and walked towards the window. He pushed it open and tried to climb out without dropping Aron. "Hold on, I don't want to drop you," he warned her.
Aron quickly grasped Danny's shirt as he went down from the window. "Well, not that tight," Danny told her. "I'm sorry, you said to hold on," Aron said with wide eyes.
"Look, I know you're scared, but we have to get out of here," he said as he let go of the castle and landed on the ground beside it. "You can let go now,"
"Not 'till we get home," she demanded. "Well, okay, but we need to get out of here before Plasmius notices us escaping," he said as he ran toward the direction of Amity Park.
Then all of a sudden, Plasmius materialized in front of the teen and the filly as he startled them both, but mostly the filly.
"Where do you think you're going," Vlad said darkly.
Danny tried to morph into his ghost half, but the two white rings wouldn't appear around his body. "Leave us alone, Plasmius! You're going to scare this filly to death!" he said as he pointed at Aron. Aron stared at Plasmius with wide, fearful eyes.
Plasmius was about to attack them both when a familiar voice came to freeze them in time.
"Time out!"
Clockwork materialized in between Vlad and Danny as he put a time medallion around Aron's and Danny's neck.
Danny and Aron blinked until they saw Clockwork in front of them. Aron (finally) let go of Danny and backed up behind him. Danny saw Aron back away and picked her up, saying, "Aron, relax. This is Clockwork. He's a friend of mine." Aron looked at his red eyes with a little fear but then she calmed down. She looked down at the time medallion and asked, "What's this supposed to do?" she asked quietly.
"We can explain later. For now, I have to tell you something. But you two will have to come with me, and Danny?" Clockwork asked as he looked over to Danny.
Danny looked away from Aron and looked at Clockwork. "We're going to need to take Vlad with us," Clockwork added.
Clockwork took out another time medallion and put it around his neck. He then quickly moved Danny and Aron out of the way so the ghost ray wouldn't hurt them. "Huh? What happened?! Who are YOU?!" Vlad then demanded. Clockwork said he would explain as soon as he took them to his lair outside of time. Vlad frowned but came anyway.
They materialized in Clockwork's lair and looked at the screens in front of them. They showed King Pariah and King Sombra conquering the Crystal Empire. Vlad and Danny had confused looks on their faces while Aron's mouth was dropped open and stared right at the screen. "Holy sh!t! How'd he return?!"
Danny looked at Aron and then looked back at the screens. As he looked closely, he notice Pariah Dark with Sombra. Danny then had a surprised face when he saw him. He looked at the other screens by the one big screen. It showed crystal ponies running away from the empire but were suddenly stopped by an invisible shield.
The ponies didn't have their beautiful hair and sparkling body that looked like crystals. All they had were scared faces on them and they kept banging on the invisible shield.
"Looks like they're stronger than before," Danny commented as he made a shocking face when he saw a few crystal ponies laying in a puddle of blood.
"We might need a little help," Clockwork said as he looked over to a dark area where a table was that had a thermos on it. Danny looked with wide eyes and backed away a little. "W-we can't let him out," he said. "he'll try to kill me. Please, Clockwork. We can't."
"It's the only way to stop them and lock them away forever," Clockwork said as he floated over to the thermos and floated back. "I'll try to have him not kill you." he said as he smirk.
Danny just looked at him. He put Aron down and twisted the cap of the thermos open.
"He better not kill me…"
