I don't own Danny Phantom.
Danni's icy blue eyes fluttered open slowly. She shot up, expecting the flaming-haired ghost to be there. To her surprise, she was lying in her bedroom.
"My… bed?" the female halfa asked, to no one in particular. "How did I get here?"
Her door opened. "Allow me to answer that." A teen in a black sweatshirt that masked his face, blue jeans, and red sneakers walked in, carrying a tray with a bowl of chicken noodle soup and a glass of water.
"Who are you?" she demanded. "And how did I get here?"
"I'll tell you my name later," the teen said, placing the tray at the foot of her bed. "I carried you here. Dan knocked you out really good, probably due to shock."
Danni narrowed her eyes. "Who's Dan?"
The boy took a breath. "The ghost who attacked you."
In a flash, Danni shot up and lunged at him. He flipped to the side and landed on his feet.
The female Phantom's head shot up and she growled at him. Two of her teeth had sharpened into fangs and were barred at him. She growled and fired an ectoblast.
He absorbed it in one hand and shot it back at her. "Listen, girl! I don't want any trouble!"
She dodged the attack and fired another from her foot. "Well, sorry, pal! You know something and that's dangerous!"
He brought up a ghost shield to block the blast.
Danni stalked up to him, ectoplasm charging in both of her hands.
"STOP IT, PHANTOM!" the boy yelled in a voice filled with authority. "YOU'RE NOT THE ONLY HALFA HERE!"
The results were instantaneous. The energy around her hands faded away and fangs retracted back into teeth.
"B-b-but that's not true!" she stuttered. "Vlada, Daniel, and I are the only halfas…"
"In this dimension," the teen said.
Her blue eyes were wide. "Y-y-you mean…"
"Yup, Phantom," he said. He pulled down his hood. "I'm you from another dimension."
Danni stood there gawking for a minute.
"Y-you're me?" she asked, finally.
Danny nodded. "I'm you from another dimension."
She raised a black eyebrow. "I'm a boy in another dimension?"
He laughed. "I'm Daniel Fenton AKA Danny Phantom. Call me Danny. D-A-N-N-Y."
"I'm Danielle Fenton AKA Danni Phantom. Everyone calls me Danni. D-A-N-N-I," Danni introduced.
"Judging by the fact that you called the other two halfas Vlada and Daniel," Danny started. "I'm going to say that your dimension is a gender bent version of mine." He paused. "Wow, that's hard. We'll call my dimension Dimension 1 and your dimension Dimension 2."
She nodded. "So the guy who attacked me is a male version of Daniella…"
"Daniella?"
"My evil alternate future self," Danni explained. "Dan's yours right?"
He nodded. "And I'm guessing Daniel is your clone and Vlada's your archenemy."
A ringtone interrupted the two halfas' discussion. Danni reached into her pocket and pulled out her cell phone.
"Hello?" she answered.
"Hey, sis! It's James!" Danni's version of Jazz answered. "What's up?"
Danni glanced at Danny. "Not much," she lied.
"Okay… are you out on patrol?" James asked.
"Yes," Danni lied again.
"We're coming home. The final college tour was cancelled."
Danni's eyes widened. "O-o-okay, bro. Tell Mom and Dad that I'm out with… Val. Bye!" She hung up quickly and grabbed Danny's wrist. "Go ghost! We've gotta move!"
"But-but what if someone sees us together?" Danny asked, turning into Phantom.
She rolled her eyes. "If they ask, you're my twin bro, okay?"
He nodded and watched as she went ghost. "A miniskirt while flying?"
She growled. "It's a skort."
….
Two black streaks flew across the sky over Amity Park.
"I am so beating you!" Danny yelled back to Danni.
The female Phantom rolled her eyes. "Only because I'm letting you!"
Danny laughed but it was cut short when Danni used a strong burst of speed and ended up in front of the male version of herself.
"Ha!" she yelled, rocketing off.
The boy frowned and attempted to catch up to her.
Suddenly, Danni stopped short. Danny flew up next to her.
"What's wrong?" he asked.
"Something's up," the girl whispered.
Danny was about to ask what it was when an ectoblast shot him out of the way.
"DANNY!" Danni shrieked as he hit the ground and was masked in a cloud of smoke. "Danny, can you hear me?"
"Well, well, who do we have here?" a sickening voice asked. "The Phantom girl!"
Danni froze, recognizing the voice. "You."
"Yes, me."
The girl spun around, fists blazing with ectoplasm and slammed her fist into Dan Phantom's jaw. He was sent spiraling backwards before he shook his head and looked back up, just in time to have Danni Phantom ram her whole body into him.
He regained his balance faster this time and threw some green fire at her. She flew over it and fired an ectoblast from her hands.
"You may have taken me by surprise earlier but I was too in shock to fight back." Her ectoblast hit him in the chest. "But I'm ready to fight now."
Dan's head shot up and he growled. She got into a flying fight stance.
"Look!" a girl yelled from the sidewalk.
A crowd of people gasped and looked up as they watched their own protector Danni Phantom and an older, muscular, male ghost with the same DP symbol circle each other.
The whole town was silent as the ghost and halfa waited to see who would make the next move. It was the calm before the storm.
With a yell, Dan shot forward, taking Danni by surprise. The two tumbled to the ground battling for control. Dan gained it, landing on top and pinning Danni's wrists to the sidewalk.
The female Phantom growled. She brought her feet up and kicked him over her head. He landed on his feet and slid back a little.
The destructive ghost charged at Danni, raising his fist for a punch to her gut. She dropped back into her battle stance…
…Only to be grabbed by a duplicate of Dan. He pinned her hands behind her back and shot ectoplasmic goo over her mouth and around her feet.
Her eyes widened as the real Dan came closer.
His punch was blocked by an invisible force. The ghost's red eyes widened as Danny Phantom became visible, holding his alternate future's fist with his gloved hand.
"Forget about me, Dan-Dan?" Danny taunted.
The boy adjusted his grip and slammed his whole body into Dan, throwing the latter back about 20 feet.
Danni's eyes drifted to the Dan-duplicate restraining her. Her transformation rings appeared around her waist and split, but instead of transforming her into human form, they knocked the duplicate backwards into a tree, causing it to dissolve out of existence.
She grabbed at the ecto-goo muffling her and yanked at it. It didn't budging and she fell over due to her feet being restrained. Her eyes gained a mischievous glint as she got an idea. In a flash, she shot into the air.
Dan fired a green ray at his past self. Danny's eyes glowed blue as he shot ice rays out of them, freezing the ray. The teen caught it before it could hit the ground and threw it into the air. He slammed the heel of his boot into the chunk of ice, sending tiny ectoplasmic ice shards flying at Dan.
The ghost didn't have time to dodge and the shards dug into his skin. He howled in pain. "You little brat!"
Danny narrowed his blazing blue eyes as his hands glowed neon blue. Dan narrowed his blood red eyes as green fire danced in his hands.
Suddenly, both stopped.
"Hey, old man," Danny said. "Do you hear that?"
Dan nodded. "Yeah, it sounds like a—"
Green sonic waves flew out of Danni's mouth as the ecto-goo melted away.
"—GHOSTLY WAIL!" Dan finished, as both he and Danny were sent flying backwards.
Dan slammed hard into a tree knocking it down and Danny flew past him, landing in a bush.
Danni struggled to keep her green eyes opened as she fell to the ground, weakened.
"Danni!" Danny yelled as he jumped out of the bushes and ran over to her.
"Danny?" the ghost girl asked as her eyes fluttered shut.
A chuckle lit up the silence. Dan had gotten up. "Oh how sweet! I could puke." He raised a hand and created a portal. "But I have better things to do."
Laughing manically, the evil ghost flew through the portal.
Danny's eyes narrowed. He picked Danni up and held her bridal style before jumping into the portal to follow Dan.
The onlookers watched as the portal disappeared behind their heroine, some boy who looked like her, and an older male version of her.
Yes, the next chapter will be another dimension. And I think you guys are gonna like the version of Danny from that dimension.
