Story (c) Me

Eventually all the ponies reached Sugarcube Corner. Tucker whistled at the bakery. "Man, that place looks like a gingerbread house. Sweet!" he said. Pinkie Pie nodded, excited.

"Yep! And the party's inside! I-"

"I finally caught up with you guys!" Spike cut off Pinkie Pie, running in and almost crashing into the three new ponies. He stopped and looked up at them. "Who're you three?" he asked, surprised. Twilight stepped forward.

"Oh, Spike, these are, um, our new friends. They're here under unusual circumstances which I'll explain later." she said. Spike shrugged.

"Good enough for me. What are your names?" he asked.

"Danny."

"Sam."

"Tucker." After all three said their names, Spike's eyes caught Tucker's cutie mark.

"Hey...you have a strange cutie mark there. What is it?" he asked, peering at it, interested. Twilight Sparkle coughed.

"Again, they're here under unusual circumstances, Spike. They're not exactly from here. I'll explain everything. Also, did you mail that letter I wrote to Celestia?"

"What letter?" he asked, frowning. Twilight frowned as well.

"You know...the letter I left on the table next to the other note...that was supposed to be mailed to Celestia?"

Spike tried to think back. He had saw the note and another paper by it, but he had grasped onto the first note and forgotten about the other one on his way out. "...Oops." he said, almost chuckling a little.

"It's kind of important; do you mind going and sending it and coming back? No rush. The party's still going to be here when you get back." Twilight said. Spike sighed.

"Okay. Be back soon. Nice to meet you new ponies!" he said, running off. Sam smiled.

"Aww, he was so cute!" she said. Twilight giggled.

"That's my assistant, Spike. He's a baby dragon. He'll be happy to tell you all about himself later. C'mon." she said. They went inside and Pinkie guided them to a room- they looked inside, surprised by all the party decor and snacks that Pinkie set up. Balloons hung around the room. Pinkie Pie bounded in the room.

"Let's have some fun, guys!"

All the ponies including the trio couldn't help but smile. Danny found a place to put down the bag full of stuff they carried and began to have a fun time. Spike showed up soon and had fun as well. Tucker was snacking a lot- not unusual for him at all- and Fluttershy began to open up a little bit around them. Rarity decided to ask a question. "So, guys, I know you're not from here...but, um, what exactly are your cutie marks inspired by?" she asked. They shared a look. Danny shrugged.

"Well, I've always wanted to be an astronaut, and I enjoy stargazing, so I suppose my cutie mark would be from that." After him, Tucker was happy to answer.

"I'm guessing that since I love technology so much- don't know where I'd be without it- and I love my PDA so much, that's what it would be."

Sam was next. "Well...I like to garden and I'm interested in the environment, so that might explain the roses. But I'm also goth, so that's why I'm assuming they're dark purple."

"Goth?" Rarity asked. Sam smiled.

"Yes; it's a style- we typically like dark things and that sorta stuff."

"Interesting!"

"Thanks!"

They chatted and had fun for awhile longer. Danny stopped short for a moment when a puff of blue air came from his mouth. Everyone saw it. "Hey...what was that? Are you cold?" Rainbow Dash asked.

"But it's decently warm in here." Applejack put in. Danny and his friends shared a nervous glance.

"Um- if you'll excuse me, I'll be right ba-"

"Going somewhere, Danny Phantom?" a familiar voice of a pestilent ghost came from behind. All the other ponies and Spike with the exception of Pinkie Pie screamed and ran for a hiding spot. Danny, Sam, and Tucker turned around to see a blue ghost with a glow about him and a box cutie mark floating in the air, waving his hooves up and down, trying to be scary. "I am the Box Ghost Pony! And I will not allow you to defeat me once again!"

"Okay, you know what? I don't even know how you got here, why you're here, or how you manage to annoy us everywhere we go."

"It is my job to inflict terror into hapless people or ponies! For I am the Box Ghost Pony!"

"We know!" all three said at the same time. Pinkie Pie grinned and stuck her tongue out at the ghost.

"I won't fear you!" she said. The Box Ghost grinned.

"Is that so? Well, you will not be saying that after I unleash pure terror!" he declared. With that, boxes surrounded by a ghostly aura flew through the walls, earning more screaming from the ponies. The Box Ghost threw them around Pinkie Pie, pushing her against the wall and then down to the ground to hold her down. She let out a cry of surprise from it. Danny grimaced. While he doubted that the boxes could do any bad things to Pinkie, he was worried that if he didn't go ghost to at least throw a few punches and get the Box Ghost down, that he could actually cause a little damage.

He wouldn't let that happen. He let out a sigh of defeat. "I really, really hate you right now, Box Ghost...but I guess the others were gonna find out my secret eventually..." The pegasus nodded to his friends. The rest of the ponies were wondering what on earth he was talking about, but found the answer in seconds. "Going ghost!" Danny jumped into the air and allowed a glowing ring to surround his waist. It split apart and traveled up and down his body. His white body became a pitch black, and his hooves became white. His hair became white and his eyes green. His cutie mark changed into the DP symbol. With a flash, the transformation was complete. Gasps came from about the room.

Danny floated up and launched himself at the Box Ghost, knocking said ghost to the ground. He hit him with an ectoblast for spite and then froze him. He looked to his friends- Sam already had the thermos in her mouth. She popped the cap open and dropped it, Danny jumping back. The Box Ghost was captured in a blue light from the thermos with ease. Tucker pushed the cap back on the thermos with a sigh. Danny floated down and his friends walked up beside him. Pinkie Pie had pulled herself out of the pile of boxes and was slowly approaching Danny. The rest of the ponies began to carefully come out of their hiding spots, with the exception of Fluttershy, who was still cowering under a table. They walked up to the three, watching them with cautiousness. Pinkie was the one who came up closest and was the first to ask a question.

"What was that?" she asked, eyes wide. Danny groaned.

"I knew you guys would figure out eventually..." With the ring forming again, he changed back to normal. "It's a long story. Basically, well...I'll be honest. I'm...half ghost."

"What?" Rainbow Dash asked, confused. "How's that possible?"

"It was an accident in my parents' lab. They had built a portal to the ghost world...it didn't work. So, with my friends here watching, I decided to try to go in, maybe see if I could fix it. But...I accidentally pressed the on button when I was there. I ended up being electrocuted and blasted with ectoplasm, the basis of ghosts. As a result, I became half ghost. I decided to fight crime as a superhero known as Danny Phantom. I have ghost powers. That's probably why that ghost unicorn tried to get rid of me and my friends- we'd try to put a halt to whatever she's planning. My parents don't even know I'm like this- only my friends here and my sister, and you guys now. Oh, and my arch enemy, but I'd rather not talk about him."

There was a long silence. Spike finally whistled. "Twilight was right; you guys aren't from here at all."

"No kiddin'." Applejack mumbled, eyes wide. Danny saw Fluttershy somewhat interested in the story, but still too afraid to come out. He frowned.

"Fluttershy, I...I don't blame you for being scared, but I'm not dangerous. Cross my heart. I'm sorry if I scared you." he said. Fluttershy carefully came out of her hiding spot, timidly getting a little closer- but not too close. Rainbow Dash managed to smile.

"Well, Danny Phantom, thanks for saving our behinds there."

Danny grinned. "Don't forget Sam and Tuck, too. They captured him. Really, that was the Box Ghost. He's pretty much the lamest ghost ever. I've faced guys way worse than him."

"I wanna see your powers!" Pinkie said excitedly. She looked at Danny pleadingly. "Please?"

Danny blushed and shrugged. "Well...they're a bit dangerous to try in here. Maybe tomorrow if any of you guys know a good spot where no one can see us? I have a secret identity for a reason." he said. Applejack grinned.

"I think I know the perfect spot. Tomorrow is fine."

"I-I can come, too..." Fluttershy murmured timidly. The trio couldn't help but grin. Fluttershy, even the most timid, had some level trust in them. Twilight frowned.

"Wait- you said your parents don't know about this?" she asked, surprised. Danny cringed.

"Um...no. Well, I used to be afraid they'd reject me- they are ghost hunters- but now that's not it. I know they'd love me, but I'm just not ready yet. I'll tell them when I'm ready." he said. Twilight frowned, but nodded.

"In all truth, Danny, it was probably better that they found out now. They see how unique you are- and in a good way." Sam pointed out. Danny softly grinned. Tucker looked at the two ponies sharing a gaze, then deviously grinned.

"He didn't mention that it was Sam who convinced him to go in. He'd do anything for Sam,the two lovebirds." he said. Danny and Sam blushed violently and turned to glare at Tucker.

"We are not lovebirds!" they both snapped. All others gave an 'aww'.

"You're sure you're not together?" Rarity asked. Both Danny and Sam shook their heads.

"Of course not!"

"Oh, really?" Rarity giggled. "What a shame."
