Alright! Here it is, my first fanfic! Hope you like! Oo R&R please! :) Oh, and I forgot, I don't own either Kim Possible or Danny Phantom.

Chapter 1: Box Ghost

It was a sunny day at Casper High; Danny Fenton was taking a biology test. "Ugh, how am I supposed to know which side of your heart is your left!" Danny said quietly to himself. Suddenly the fire bell went off, right as blue mist came out of Danny's mouth.

"Oh no," Danny complained to himself. The class lined up and filed out of the classroom, except for Danny. When he was alone, two bright blue rings appeared around his waist and separated. One went upward while the other downward. When the rings disappeared Danny Fenton no longer stood, a boy with a black and white jump suit, white hair, and glowing green eyes now stood where Danny Fenton used to, Danny Phantom was back! Danny went intangible and fazed through the wall, into another empty classroom. He easily spotted the box ghost, of course, playing around with some boxes. "Hey box geek!" Danny yelled out before shooting ecto plasm at the ghost. "I'd like to see you make a box out of THAT!" Danny remarked. The box ghost turned around to face Danny, "BEWARE!" he yelled out before charging Danny. Realizing how close the ghost was he smirked and right at the last second side stepped out of the way, sending the box ghost flying into a wall. "Hey ghost!" Danny yelled as he whipped the Fenton Ghost Thermos (sorry I forgot what it's called!) and shot the blue beam at the box ghost, sucking him inside. Danny fazed through the wall and out to the football field he quickly turned invisible and flew over to his class. He landed behind Sam and Tuker, his two best friends. They covered him while the rings reappeared and turned him back in to Danny Fenton.

Kim Possible was racing down the crowded school hallway, screaming "RON!" when Mr. Barkin stepped out in front of her.

"Hold it Miss Possible, there's no running in school hallways. Now, what seems to be the problem?"

"Sorry , and I got a mission finally!" she said excitedly, suddenly Ron Stoppable stepped out of from behind Mr. Barkin . "Really?" he asked. "YEP!" Kim practically screamed. "YAY!" Ron yelled. Ever since that Danny Phantom kid revealed himself, we haven't gotten any missions! Kim thought before racing out the school doors to her purple sports car, with Ron right behind her. She jumped into the drivers seat at the same time Ron jumped into the passengers, both crime fighters slamed there door shut. Kim imediatly drove to her house and changed. She through Ron's mission clothes (they always kept a seperate pair at each othere's house) at him, hitting him smack in the face. "Oof, hey watch it KP!" Ron said before taking his clothes into the bathroom to change.

A while latter, Kim was driving down the enterstate. Finally, we get to meet and fight along side this Phantom kid. Kim thought. When they drove into Amity Park, Kim saw a boy with snow white hair, glowing green eyes, and a black and white jumpsuit on, hovering in mid-air. "Holly crap, it's Danny Phamntom!" Ron yelled. Jump suit, soooooo last year. Kim couldn't help but think. She pulled over and stopped the car, before climbing ontop of it. "HEY!" she yelled, he seemed to be day dreaming, when out of no where he disapered. Kim looked around, before turning to look beside her, and nearly falling off the car, he was standing, well floating right beside her. "Oh, hi!" She said. He simply looked worried and pointed behind her. She turned just in time to duck as an ecto blast came right toward her.

•••••••••••

"WHERE DID THAT COME FROM!" Kim yelled. Danny replied, "It came from my arch foe, Vlad Plasmius. He's stand-well er floating over there." Danny nodded over toward a ghost wearing a black and white suit, his hair up in two giant black points, his skin was a slight blue color,and his eyes were a bloody red. That is the scariest living thing I've seen! Kim thought, here eyes were as wide as sawcers. Danny walked in front of her, and shot an ectoplasm blast at Vlad to get his attention. Vlad turned to him "What is it you want Daniel?" He asked, venom dripping from every word. "Don't include her," Danny yelled, pointing towards Kim,"this isn't her fight!" he said. He handed Kim a belt and told her quietly, "When he gets near you, strap this on him, he'll loose his powers and he won't be able to take it off." Kim nodded. Danny flew up to Vlad, turned invisible and flew behind him. He raised his fist and yelled "Hey Vlad!", as soon as Vlad turned around Danny hit him in the face, sending him crashing into the ground. "You seriously are, one crazed frootloop." Danny says. Vlad smiles then turns invisible. "Where'd he..." Kim started when suddenly Vlad put his hand over her mouth. "Hey! GET OFF OF HER!" Danny yelled as he started to fly over. "Ah ah ah, fly any closer and Kimmie here will get a mouth full of ecto plasm."Vlad said. His hand started to glow green menecingly. Kim lokked at Danny,winked,and grabbed Vlad's hand, and in one swift movement, flipped him over her shoulder. As soon as he hit the ground, Kim jumped ontop of his chest. "Ow!God, how much do you weigh!" Vlad shriecked. "None of your buisness." Kim and Danyy said at the same time. "Jinx!" Kim yelled, then looking at Danny said, "You'll never beat me to the acursed jinx button." Kim and Danny started laughing. "Laugh all you want, children, because I will be the victor." Vlad said. Kim looked at him then whiped out the belt, and said," Actually, we will." And with that she straped the belt onto Vlad, then did a double back flip off of him. She landed in a crouch. "You sure that will hold 'em?" Kim asked looking up at Danny. "It'll have to do for now. We'd better get outta here." Danny explained, "He won't be very happy when he gets that belt off." And with that, Danny flew off,leaving Kim to run to her car. " I'll get you for this!" Vlad screamed after them. "Ya ya, whatever." Kim and Danny both yelled over their shoulder.

•••••••••••

"Soooo,how did you get your powers?" Kim asked Danny. Wow,she has a lot of questions. Danny thought. Kim, Ron, Rufus, and Danny were all sitting in Danny's room. Danny was on his bed, Kim was sitting criss-cross-applesauce on the floor, and Ron was in a chair, Rufus was sitting on Ron's shoulder of coarse.

"I got my powers in a lab accident. My parents built a portal to the ghost zone and it didn't work, so I looked inside to see if I could fix it. Sadly, I did. My elbow brushed up against an On/Off swich and a bright light appeared. Next thing I knew, I had snow white hair and glowing green eyes."

"Sooo...do you think I could get those powers as well?" Kim asked.

"Oh, believe me, you don't want 'em."

Kim gave Danny the puppy-dog pout.

"Awww, alright, common." Danny surendered.

"YES!" Kim yelled, pumping her fist into the air, then pulling it back down.

Kim, Danny, Ron, and Rufus made their way down to Danny's parent's lab.

"Woah...this is your lab? It looks like one of Drakken's lairs. Just, less evil." Kim and Ron echoed each were looking at a room, with weapons scattered all over the place.

"Yup, but I wouldn't suggest you touch anything, who knows what types of sideaffects these things have." Danny walked over to a arch with swirling green mist in it, he grabbed a well hidden orange cord, and unplugged it, turning the portal off. He then walked inside and pressed the switch, walking back outside of the portal, he plugged it back in, but nothing happened. "Alright, it's ready for you to-" Danny started, but Box Ghost came flying out of no where. "BEWARE!" he screamed before flying off again. "Um, okay was random." Kim said, arching and eyebrow. "Anyways, it's ready." Kim gulped and stepped in. "So all I do is flip the on/off switch and stand here?" Kim called from inside. "Yeah!" Danny replied.
