CSI: Phantom

Chapter 1

A Ghostly Warning

The noise of New York traffic can be heard from the lobby of the Roosevelt Hotel as four certain teenagers entered the lobby. The oldest of the four, Jasmine Fenton or "Jazz" as everyone calls her, turns to the other three.

"Why don't you guys go sit down while I get us checked in?"

"Sure, Sis," yawned Jazz's younger brother, Daniel or "Danny" as he prefers to be called.

Danny and his best friends Tucker Foley and Samantha "Sam" Manson went to the couches, dragging their luggage in tow. They plopped down, exhausted. Danny was not your average everyday teenager. In reality he can change into his half-ghost alter ego, Danny Phantom.

"Remind me again why we're going to this stupid ghost convention?" whined Sam.

"Because my parents were banned for life last year for destroying half the Chicago Convention Center," said Danny. "They thought a guy dressed as a Ghost Pokémon was a real ghost."

"Let me guess: they now want us to go to GhostCon in their place," said Sam.

"Bingo," replied the raven-haired teenager.

"Which Ghost Pokémon?" asked Tucker.

"I don't know. They don't know Pokémon!"

Jazz walked towards the trio with room keys in hand. "We'll be on the fourth floor. Room 410 will go to Sam and me. You and Tucker will get Room 411." She tossed a room key to each member of the trio.

Team Phantom went into the elevator and up to their respective rooms. Bidding each other good night they disappeared into their respective rooms, hoping for once they can enjoy an uneventful vacation.

Danny's ghost sense went off at around three in the morning, waking him up. Not wanting to wake up Tucker, Danny transformed into Danny Phantom. His pajamas were replaced with a black jumpsuit complete with white boots, white gloves, and a white DP insignia on his chest. Turning intangible, Phantom flew out of the window and came face to face with the ghost of a woman Danny has never met before. She looked to be in her late 20s and Danny could see she was Italian American. She had her arms crossed with a serious look on her face.

Danny stared at her with an equally serious face. "Can I help you?"

The woman smirked. She raised her hands, showing she was unarmed. "You can start by taking it easy, kid. I'm not here to pick a fight." There was a small hint of a Long Island accent in her voice.

Danny didn't buy it. "If that's the case, then why are you floating in front of my hotel room? It's the middle of the night!"

The woman chuckled. "It's called the 'City That Never Sleeps' for a reason."

"Don't change the subject! Why are you here?" Danny was getting annoyed now.

"All right," the woman sighed, "I came to warn you."

"Warn me? About what?" asked Danny now confused.

"Something is going to happen at GhostCon tomorrow," the woman said, now serious again.

"What's going to happen?" asked Danny.

"I don't know exactly, just that something fishy is going to happen tomorrow and it won't be pretty."

"And how do you know this?"

"I saw three talking green vultures talking amongst themselves back in the Ghost Zone. Something about their boss trying an experiment during GhostCon tomorrow. I overheard one of them saying that the 'Ghost Kid,'" she added air-quotes at that, "would be in New York City and that their boss should be on his toes. I already knew that they were talking about you."

Danny didn't have to ask how she knew he was the Ghost Kid. Danny had quite a reputation in the Ghost Zone. Wait… three talking green vultures? His thoughts immediately went to his archenemy and rival, Vlad Masters aka Vlad Plasmius.

"I know those vultures," said Danny, "They work for a ghost by the name of Vlad Plasmius. He hires them to do his dirty work, which I don't know why he hires them in the first place because Plasmius is plenty strong without henchmen."

"I take it you and your friends are going to investigate?" asked the woman.

"I'll see what I can do."

"That's good enough for me, Danny Phantom," she smiled and started to fly away.

"Wait! Who are you?"

"Detective Aiden Burn."
