Haven't written a one shot in over a month and I thought it was about time. Enjoy my attempt at giving Dani some sort of character.

Dani Phantom was on a mission. Well, it was more of a 'I really want to fuck shit up' kind of situation, but it might as well have been a mission.

She had been working on the finer details for a while, making sure everything was in place and ready. She measured herself every day for a month and cut her hair short specially. She had tried to get it as close as possible to Danny's choppy cut, although it was quite difficult when all she had were a pair of kitchen scissors she had stolen from someone's kitchen. She had every intention of returning them. at some point.

Now, after months and months of planning, she was ready. She had grabbed one of Danny's shirts from his closet when he was at school along with a pair of his scruffy jeans. Pulling them on and grimacing when the jeans were just a little too long, she surveyed herself in her clone's mirror. Just right. She figured that Danny usually wore his pants long anyway so they wouldn't be a problem.

Time to have some fun.

Danny would be home from school in ten minutes or so, according to the clock on the wall. Great. Just enough time for Dani to lay out that bucket of ectoplasm on his door and then go and see his parents. They would be her test subjects before she brought her mischief into the rest of the world. If they figured out she wasn't Danny and locked her in a ghost proof cage, he would be home in no time to let her out. If they bought it, she could carry on with her plan. Dani giggled.

She went down the stairs to the lab, not bothering to tiptoe like usual. Maddie and Jack Fenton were messing around with something that looked like it could definitely kill Dani, so she steered clear of the actual machine, choosing to clear her throat instead to alert them to her presence.

It worked like a charm.

"Ghost!" Jack shouted, spinning round with an ectogun pointed right at her. Dani, who was not quite used to people pointing large guns at her, gulped.

"Jack!" Maddie scolded. "It's Danny. Hi, honey."

"Hi mom." Dani said, hoping her voice sounded deep enough. She knew Danny's hadn't broken yet, but he was still naturally deeper than her.

"How was school?"

"Fine. You know, the usual."

"Were there any ghosts?" Jack boomed. Dani couldn't quite get over how loud his voice was.

"Nope. No ghosts, dad."

It felt strange calling the Fentons 'mom' and 'dad', mostly because her only experience with parental figures was not exactly positive and she spent most of her time alone or in the ghost zone. She never had need for parents. Danny had also given her clear instructions to stay away from Maddie and Jack because they had scanners and guns and things she really didn't want anywhere near her.

"Aaaw." He whined. "There are never any ghosts."

That stupid Danny Phantom fights them all. You know, Danny," Maddie said. "We were wondering if we could you and Jazz to keep an eye out for him. You could call us and we could come and calm the situation and capture Phantom."

"For dissection!" Jack put in happily. "We want to tear him apart molecule by molecule!"

Dani tried not to throw up right there. "That's great." She choked out. "I'll call you if I see him. I'm gonna go and do my homework now. Lancer gave me loads."

"I swear they give kids way too much homework nowadays." Maddie muttered under her breath as Dani ran up the stairs. "They get virtually no free time."

Dani puffed as she lay her hand on the wall. She really needed to build up stamina, she thought distantly.

Operation fool Fentons had been a success. Now it was time for operation fool Sam and Tucker. This one would be a lot harder.

She flew invisibly along the streets until she saw the trio of friends. Sam was complaining about something – her mother probably – and Tucker was cradling his PDA. Dani still didn't understand what his obsession with that thing was. Danny himself was wandering a few paces behind. Perfect. Now all she needed was a distraction.

As if on cue, Skulker materialised in the air above. Dani quickly rushed up and turned both of them invisible, flying them out of the range of Danny's ghost sense before he could pick up on either of them.

Skulker spluttered, revving his engines and preparing to fight whoever had attacked him.

"Whelp?" he growled. He looked at Dani properly. "You're not the whelp."

Dani, who had switched to her ghost form which did look different to Danny's, grinned. "You got that right." She said. "I'm Dani. Nice to officially meet you. I need a favour."

Skulker looked understandably confused at her bluntness, and his gun swivelled round to point at her. "Who are you? Why do you look like the whelp? What do you want?"

She smiled sweetly at him, making him shudder. "Already said, I'm Dani Phantom. With an i." She answered. "Plasmius cloned the Danny you know, and I'm the result. I'm playing a prank on him."

"A prank you say?" Skulker mused. Dani nodded. "I'm in."

"Really?"

"I've always wanted to pay back the whelp for all the times he's beaten me into the ground. What do you need me to do?"

Dani grinned again. She could tell Skulker was getting excited. "Just need a distraction." She told him. "Up for it?"

He nodded gleefully in response, flying back into town where Danny was still with Sam and Tucker.

Brilliant.

With Danny safely out of the way fighting Skulker, Dani made her way to his friends. She stayed hidden for some time, making sure it would be plausible. Danny did take some time to finish fights after all. After about ten minutes, she jumped out of her hiding place and landed on the pavement with the two teenagers.

Tucker started, dropping his PDA on the ground. "Danny!" he whined. "That was new! I could have cracked it."

"That was quick." Sam commented. "Skulker not feeling up to you?"

Dani shrugged. "Nah. He can't hold a candle to me. Just took a few ectoblasts and some ice. You, know?"

Sam laughed, beginning to walk again. "Speaking as someone who doesn't have ghost powers, no I don't." her eyebrows drew together. "Anyway, as I was saying before Skulker turned up, my mom bought me that new dress the other day, and it was bright pink with those little flowers she knows I hate and then when I tried to dye it black, I only got dye all over my hands because I forgot to wear gloves and the dress is still pink! It's not even a horrible dress – it's not got like, frills or anything. It's just pink. It's not fair! Then mom came in and started laughing her stupid blonde head off."

Tucker who had been ignoring her for most part, butted in with, "Aren't you blonde, Sam?"

"Well yeah," she admitted, "But in case you couldn't tell, I dye my hair because no one wants to look at something that infuriatingly bright!"

"So, what did you guys think of Lancer's lesson today?" Dani said, getting sick of the topic of how much Sam hated her parents. "Macbeth is boring." Danny had said they were doing Macbeth in class the last time they had spoken and she hoped that hadn't changed.

"Dude, you weren't even there for most of it." Tucker pointed out.

"And you were asleep for the rest." Sam added.

"Yeah, because it's boring."

Sam sighed. "I don't know why you two hate Macbeth so much." She said. "It's one of the only plays we study with a strong female character who isn't completely dependent on a man. Not that I agree with murder or anything, but you can see why she thinks what she thinks and why she wants all that power."

"Who's lady Macbeth?" Dani asked, getting rather interested. She might actually have to read Macbeth at some point. Power hungry character and murder? It sounded like just her sort of thing.

"Trust you not to know one of the most important characters in the play." Sam scoffed. "Macbeth's wife? Arguably the character who causes the pivotal moment in the play. Ring any bells?"

"Like you said, I was asleep!" Dani defended. Hopefully Danny did actually sleep through enough of it that he was just as ignorant as her. she wasn't sure how much longer she could pretend to be Danny. Sam and Tucker were exhausting. "Hey, looks like we're at my house. See you guys tomorrow."

"But dude!" Tucker said. "You said you'd go to the park with us."

Shit. "Yeah, well." She stuttered. "Sorry, Skulker got me with one of his guns. I gotta go bandage it quickly. I'll see if I can meet up with you later. Sorry guys."

"You're injured?" Sam asked, brows raising. "Let me see."

"I can really take care of it myself!" Dani assured her. she felt sure her voice was rising again and she did her best to keep it low.

"If you're sure, dude?"

"Yep. Totally sure. See you later!" Dani ran up the steps to the front door and phased through. Gosh, this was more stressful than fun as she had originally intended. Well, there was always time for more. She snuck out of the window as she heard Danny come in through the front door.

This time, she didn't try to impersonate Danny again. She just hid in the pond at the park and splashed people passing by. Mostly that blonde jock that bullied Danny. His face when he got sopping wet was hilarious and she had to stifle her giggles. When she got bored of the pond, she moved on to picking up pieces of food while invisible and whistling through her teeth. She terrified a few older couples with that.

Dani didn't have the longest attention span, and she soon grew tired of that too. Then she spotted a gaggle of high school age girls, quite possibly from Danny's class, near the water fountain.. She grinned.

Turning visible again and checking over her clothes to make sure they were still suitably Danny like, she wandered over to them.

"Ew!" one of them – the one with the hideous pink crop top - screamed. "Loser!"

Well that was rude. Dani pushed her into the fountain.

The screaming grew louder, but it was well worth it from the look on her face. One of the other girls stepped forward to ask, "Fenton?" but Dani simply gave her a shit eating grin and pushed her in as well.

She supposed she should probably feel bad, but she was pretty sure these were the girls Danny complained about whenever they met. She didn't have it in her to be sorry.

"Oh my god!" she gasped in mock astonishment. "Don't know what came over me. So sorry!" with that, she pushed in the last girl in the group. Then she realised what she'd done. "Oh shit, Valerie!"

Valerie glared up at her from the fountain, hair plastered to her forehead and looking absolutely livid. "What the hell, Danny?" she spluttered. "Are you even Danny? Are you overshadowing him, ghost?"

Shit shit shit shit shit. Dani ran for it, followed by a soaking wet and angry Valerie. She decided she should probably end her fun now. She just needed to prank Danny.

Hopefully he had already found the present she left in his room, but she wanted to confuse him. On her way to Fentonworks, she thought up all the wonderful things she could do.

She rang the doorbell this time, trusting that his parents would be in the soundproof lab downstairs. Danny answered it, drawling something about his parents working before he did a double take as he saw who was at the door.

"What the hell?" he muttered. "Amorpho?"

"Who?" Dani asked.

"Come on, dude. You promised you'd stay away!" Danny said. "I really don't want to have to fight you."

"I'm not 'Amorpho'!"

"Yeah right. Who else do I know who loves pranks and goes around looking like me?"

Dani giggled. "Me!" she said. "It's me, Dani!"

"I'm Danny." He corrected. "Go away, dude."

"No, stupid. Dani. Your clone? I cut my hair and stole your clothes. Hope you don't mind."

Danny facepalmed. "Of course you did. I guess that bucket of ectoplasm that I had to wash out of my hair was you as well?"

"Yep!"

"Dani! Ectoplasm's hard to get out!"

"Oh, I know."

"I hate you sometimes." He groaned.

"I am basically you." She pointed out. "How can you hate yourself?"

He grinned. "Why don't I show you? I'm gonna take you to Klemper's lair and leave you there. See how you like that."

She gasped. "You wouldn't!"

"Try me."

"Fuck you, dude." She said. "I'm outta here."

"Dani!" he cried, scandalised. "You're far too young to be using that kind of language!"

"Danny, I'm you. Any and all swear words I say are your fault."

"Shut up." He muttered.

"You shut up."

"No you shut up."

She shut him up with a gag of ice, laughing at his misfortune. She absolutely did not regret making a detour to Amity Park.

I didn't realise there was so much swearing in this until I read it over just now. Oops.
