Deception

"Muhahaha!" Laughter reverberated around the small cavern, bouncing off all the scientific equipment lining the walls, "I've finally found a way to gain world domination," shouted a short, blue man hysterically, standing in the middle of the room.

"Uh huh. Right. What is it this time?" replied a sarcastic, pale green woman reclining in a chair, filing her long, painted black nails, "Wait, don't answer that; I don't care."

"Ah Shego, you have no faith in m-"

"Doy!"

"-grr don't interrupt! Anyway, with these two ray guns I invented-"

-cough-

"SHEGO! These two ray guns will be the end of Kim Possible as we know her and then there will be nobody who can stop me in taking over the world!"

End of Kimmie? Yeah right, how many times have I heard that one?"Well what do they do?" Shego asked in a bored tone, hiding her deep interest in the conversation.

"Well..." Drakken aimed the gun in his right hand at Shego and fired. A yellow beam, shot out of it and smacked into the surprised woman. Even her lighting fast reflexes couldn't help her here but when nothing seemed to happen, anger with a side dish of betrayal rose in Shego. She stood up and stalked over to Dr Drakken who was shaking and hitting the gun whilst nervously glancing up at Shego approaching.

"What the hell do you think you're-" then, to Drakken's relief, Shego halted. Her brow furrowed as she simply stood on the hard ground glancing over her body which seemed to be changing. Shego could tell she was getting shorter and when she looked walked over to one of the many consoles she noticed her face had gained a more youthful look. Her long black hair had also shortened, stopping half way down her back and her green tinted skin, paled even further and lost the green hue.

"Well, in short, I knocked your age down a few years. Guess who you're now the same age as?" He asked in an annoying sing song voice.

"Kimmie. Hmm, for once you've got a useful invention. Thanks Dr D," she said quietly whilst smiling slyly at her renewed youth.

"Not a problem. Now, hold still while I use this one," Shego looked suspicious, but did as her employer told her, seeing as the first one worked wonders. This time a blue beam hurtled towards Shego. Well at least they aren't rays to directly kill my Princess. Wait, I meant that would be disrespectful to her...I should be the one to kill her, and in hand to hand combat! With plasma too...Shego thought while they waited for the invention to its job.

They didn't have to wait long as Shego's already defined muscles grew, pushing against her green and black cat suit, her shoulders widened, hips decreased and chest flattened.

"WHAT HAVE YOU DONE TO ME?! What's happened to my chest and what is...OH MY GOD!"

"Yes Shego! I have turned you into a guy!" Drakken cried triumphantly. Shego stood there frozen, obviously 'uncomfortable' with the situation, when suddenly she turned deadly calm and looked straight at Drakken. "Ah this is my best plan yet! From investigating the minds of teenage girls, I've discovered that all they think about is 'boys boys boys!' and now with you as a boy you can attend Middleton High School and get into Kim's head! Maybe even...distract her," he winked, "while I conquer the world!...Shego? Shego, why are you looking at me like that? SHEGO! What did I say about throwing plasma at your employer?!"

A high pitch scream could be heard as he dove under the desk, prolonging the inevitable.

XXXXKPXXXX

I don't believe this. It's not happening. Just a very bad, long, life-like dream! Shego desperately thought to herself as her first day of High School approached. Grr! I liked being a woman! Actually I loved it! And now I'm a man? Ah jeez, if Kimmie finds out about this, I'll never live it down.

She was in her room at Drakken's lair, collapsed on her soft bed. She had to change out of her favourite cat suit, as it didn't exactly fit properly anymore. It seemed Drakken had thought of this and bought her some new clothes. Needless to say she wasn't impressed. Shego liked to shop, or rather browse and then steal, for her own clothing, but what had been supplied wasn't TOO bad.

Now she wore a pair of baggy, black, hipster jeans with a black tank top with netting over it. On the material of the top was a green triangle stretching all the way down; thick at the neck and pointed at the bottom. What she particularly liked about this top was how it clung to her and showed off her, now manly, defined muscles. She also had a loose, black studded belt slung around her hips, or what used to be her hips anyway.

It had been a day since she'd been hit with the ray and, too her, a lot had happened. Drakken had pointed out that she couldn't keep her hair the way it was, much to her horror, and so after many possibilities flew around, Shego was forced to have it cut. Therefore, it was cut short (compared to what it had been like), but it was still quite long and she styled it so it looked purposefully rough and fell over her face slightly. Her nails were the next concern. Those incredibly long, sharp, strong and painted black claws were cut, filed and removed of colour. She also wore bright blue contact lenses, after all they didn't want to give Kim too many clues.

I hate this plan! How am I meant to have fun without my feminine, seductive charm? This is too sneaky as well! Okay sure I'm a thief, but I like my work to be known. Elaborate plots aren't my styleand I am SO not going to seduce Kimmie!...well...No! Shut up you-

Her internal ranting was interrupted as Drakken continued to shout new name suggestions from the other room, "Steve!" Oh for the love of- "No I don't think that suits you Shego. Hmmm," he continued to ponder, "How about we go for some uncommon names like...Shea?"

"It sounds like a girls name," she shouted so she could be heard.At least he didn't like Steve.

"It's Irish and it IS a boys name, but fine if you want to be fussy!" Shego could hear him tapping his foot and figured he probably had he lips slightly puckered with his hand on his chin; his usual thinking face. "Shen?"

"Not bad. What else you got for me Dr D?"

"Erm...I can't think of anything better that's close to your name, as you requested. I don't know why you didn't want Frank to be honest," he mumbled to himself.

"Shen it is then! I guess it will have to do," Shego, or rather Shen, grumbled, while getting up and going through to where Drakken was standing with a rucksack in his hands, modeling a rather nice burn on the side of his neck; evidence of her outrage towards this plan.

"What's that for?" she asked as Drakken passed the bag to him.

"Well, you need a bag for school! I have all the things you'll need as well, so you just have to pack it. I'm just going to write your new name on all the official documents and send them off, so we can get you into that school. Apparently, you've recently moved to the area and are living with your 'guardian'; me!

"Swell," Shen sarcastically retorted, rolling his eyes.

XXXXKPXXXX

The cursed day arrived far too quickly for the angry Shen, who was still opposed to this plan and never ceased grumbling, making sarcastic comments and predicting the doom of yet another plot to take over the world.

He stood just inside the front doors of Middleton High School, where students busied themselves around lockers and rushed through the corridors. Having reported to the reception desk, Shen had been given his timetable, a map of the school and a combination for his locker.

He had to be complicated with his plan, didn't he? Couldn't just have me younger and in a removable disguise to waltz in here and kill Kimmie. Just as he thought that, the well known crime-fighting cheerleader walked down the corridor, laughing with two friends; the buffoon and a dark skinned girl, whom Shen thought he had met before, but couldn't place it. Would you have killed her though?...Of course i would!...yeah right.

Now angry at himself as well as the situation, Shen walked forwards to the point where the map said his locker was located. Dread started to grow in his stomach, as he neared Kim and her friends who were standing around a locker, which appeared to have a computer in it.That must be Kim's locker, he thought, oh crap! This is soooo typical! Must be a mistake. He checked the number of his locker and the one in front of him, as well as the position on the map, oh man! two lockers away from Kimmie's.

Shen stopped in his thinking when he heard Kim talking into her locker, "So, whats the sitch? Anything going on in the villain world? Drakken got a new plot for world domination?"

"Nope, it's pretty quiet out there. Drakken seems to have disappeared off the face of the Earth, along with Shego." Replied Wade, the Nerd-linger, Shen thought as he recognised the voice.

"Shego's disappeared?" Kim asked, sounding and looking rather disappointed, an observation not missed by an onlooking Shen, who quirked an eyebrow and smirked to himself, "Ah well, I guess I don't get to kick her butt for the time being," Kim quickly covered.

Shen heard Wade laugh, obviously he didn't notice the cover up. I wonder what she's thinking. Just then a bell rang signaling first lesson, so , ignoring the trio and computer nerd, he quickly shoved a few things into his locker and went off in search of room 11.

XXXXKPXXXX

"Soo, how was school?" asked a curious Drakken, as Shego shuffled into the apartment they purchased.

"Fine." she replied in her now deep, monotone voice, without stopping on her way to her room, and slammed her door closed, Well actually it went brilliantly for your plan, just not so much for me.

- - -

As Drakken watched Shego enter and then leave the front room he thought,Wow, she's even good at acting like a teenager!

- - -

Shego threw her bag down onto the cream carpeted floor and collapsed on her bed, sighing. The day hadn't been too bad. After looking around for room 11, Kim had noticed Shen looking a bit out of place and so ended up walking with him to the class, which they had together along with Ron. During that class a 'Mr Barkin' had assigned Kim the task of 'looking after' the 'new recruit' which, of course, being Kim, she accepted and so they basically spent the entire day with each other.

Lunch, if it could be called that, was, to say the least, interesting. It was even worse than when Shego had first been in high school. Grey slop had been slapped onto Shen's lunch tray and after getting a sympathetic look from Kim, who also had something grey on her tray, he was guided towards a table where Ron and Monique (he found out her name in period 2) were sitting.

They all chatted to each other, with the trio asking Shen many questions he didn't want to answer. He held back quite a lot during any discussion, but opened up a little bit more when Kim practically shouted at the entire cafeteria to stop staring at him, because of his pale skin. She didn't have to do that, Shego thought as she smiled at Kim's protectiveness, but her thoughts soon soured, she only did it because she's a good guy.

The rest of the day was pretty uneventful. Most of his classes were with Kim and her friends, which worked out great for Drakken's plan. He received many stares from other students and even teachers when walking around the school. Kim seemed to want to comfort Shen and once put her hand on his shoulder and smiled at the shocked looked she got back. Kim had even offered to walk home with Shen after school, as it's in the same direction as hers, but Ron reminded her, in an annoyed tone, that they were going to Bueno Nacho. She didn't give up though, as she asked if Shen would join them, but he declined and walked home alone.

XXXXKPXXXX

Two well known friends were relaxing in a yellow booth at their favourite fast food establishment, well it was the favourite of one of them at least. The girl with long red hair just watched as her blonde friend across the table devoured his selection of Bueno Nacho food, while she slowly tucked into her salad.

"Ah. That's some good, healthy food right there, right Rufus?" Ron sighed as he finished.

"Uh huh," the naked mole rat nodded enthusiastically, as it patted it's bulging stomach.

"Somehow I don't think it's healthy. Weren't you listening in your health class with Mr Barkin?" Kim asked, while raising a curious eyebrow.

"Heh nah! Besides he insulted this establishment, so I'm just gonna carry on eating here to spite him."

"Riiight. Somehow I don't think he really cares about what you do with your life."

"Whatever KP, I'm still eating here anyway," he smiled and changed the subject, "You were rather chummy with that new kid today."

"Well it's hard moving somewhere new and Mr Barkin did give me guide duty. Why is it a problem?"

"No, no course not," he answered awkwardly, "it's just...he's a bit...weird."

"Define," Kim demanded in a threatening tone as he eyes darted up from the tomato she was stabbing to fix on her companion.

"He doesn't exactly talk much. It's like he's hiding something and well his appearance..."

"Isn't important...and we all have our secrets," Kim finished his sentence and gave Ron a look that told him she wasn't impressed by his views.

"Oh come on! He's as pale as a newly made piece of white paper thats been bleached too much! His clothes hardly help the matter."

"So your against him for his skin colour?"

"Damn, thats not what I meant," I don't like the way you look at him.

"Too many people are judging him for what he looks like. He needs some friends and I would've thought you'd look past something like that. You don't normally act like this."

At that, Monique rushed in to join them at their usual booth and chatted away, effectively distracting them from the conversation that had just taken place. Eventually, though, she got onto the topic of the new guy, but her views were rather positive.

"Omg GF! He's so cute!"

XXXXKPXXXX

By the end of the week, Shen was knackered. It had been quite a trying first few days of school and he hardly made it easier for himself. There were a some positives however. For example, Shen's ego sky rocketed from all the attention he was getting, and not the staring because of his appearance attention, but the romantic kind. Women were literally throwing themselves at his feet, of course they didn't know Shen was in fact female and the well known villainess, Shego, but he didn't care. It seemed even Kim's friend Monique kept hitting on him. Of course not all the girls were like that; many looked at Shen with outright disgust and didn't bother hiding their views.

Another positive would be how Kim had turned out to be quite a lot of fun. Shen could taunt and tease on a much more regular basis than when he was Shego and an opportunity was never missed. The only times Shen didn't tease Kim was when he felt he was pushing her too far, after all he was starting to quite like this friendship, mustn't get attached! It's only gonna be like this until Dr D gets his plan under way and then it's back to fighting...the way it should be. Her good, me bad...simple.

Although this new friendship was valued by both parties, even if Shen wouldn't admit it to anyone, they did have many disagreements and a few small arguments. The most frequent topic had been how Shen didn't hold much respect towards school and how it was run. The first time this came up Kim had asked about some homework that was due in the next day.

-Flashback-

"Hey, Shen!" Kim called from her locker to get her friends attention, who happened to be stacking something in their own locker.

"Oh. Hey Kimmie. What's going on?"

"I was just wondering if you've done the History homework that's in for tomorrow?" She asked innocently. Shen merely smiled slyly, closed his locker and leaned against it to look straight at her.

"You're kidding me right?" he quirked an eyebrow when the question was returned with a confused look.

"Look, Princess, I don't do homework. It's a waste of my time. End of."

Princess? Kim thought.

-End Flashback-

However, Kim didn't let it drop there and she tried to get Shen to do his homework, but to no avail. She continued to do so with everything that Shen didn't do, that he should when it came to school. Shen found himself in quite a few detentions, usually because of not doing homework, classwork (apparently it was below him), talking back to the teacher or fighting, even being 'inappropriately dressed' when Shen wore something that showed a bit too much skin for Mr Barkin's liking. Shen's argument had been that nobody else seemed to be complaining and gestured towards the drooling students. What followed? An even longer detention!

Kim had been quite upset; she didn't understand his attitude. How was she supposed to spend time with him out of school if he was in detention all the time? With her missions on top of that, it was practically impossible. What annoyed her even further was that Ron hadn't dropped his quest to make Kim see how 'not worth it' Shen was and his bad arse attitude was not helping her to prove him wrong.

Kim wasn't the only one getting annoyed at his persistence, Monique was as well. Ron had been pestering Kim about Shen even more as they got considerably closer. Shen was still holding out and Ron didn't like this secretive side of him and was worried for Kim's safety in case he wasn't who he seemed to be.

Nearing the end of the week, Monique pulled him aside and asked Ron what was going on in a very impatient manner.

-Flashback-

Noting the tone Monique was using, Ron figured he would just say it. An angry, impatient Monique was not one he wanted to be around for too long. "I...think I might...be-"

"Spit it out!"

"-erm, jealous?" There was a pause and suddenly Monique's face turned to one of understanding, which soon changed again, as she burst out laughing. After a lot of whining from Ron and seeing that he was truly hurt, Monique finally calmed down.

"Oh come on Ron. It's not like she's gonna ditch you. You'll always be her best bud."

"Exactly," at that Ron stormed off to his last classes of the day.

-End Flashback-

XXXXKPXXXX

Shego was crashed out on her bed, thankful the school week was over for now and was thinking about how much she was starting to like this plan, but also how she was still hating it considering how it would end. Shego was really starting to enjoy being in Kim's company, but there was a persistent side of her that told her she was evil and this was all a plan. Also, that if Kim knew who Shen really was, then none of this would've happened and they'd still be fighting, but Shego's more lenient side figured that she was still acting like herself, she just looked different...so maybe...in a tiny chance...something could happen? Grr! Stop this pathetic talk right now! Kim is the enemy and you are a bad, evil, hedonistic villainess!

Just then she heard the phone ringing in the main room of the apartment, stopping her internal feud temporarily. Drakken never answered the phone, after Shego scolded him. Someone might recognise his voice after all and then everything would be for nothing, so she slowly got up and exited her room.

"Hello?" she spoke into the receiver, "Oh! Kim, hi, sorry I wasn't expecting you to call. What's up?" After a few minutes of talking into the phone with Drakken listening intently from the sofa, pretending to watch the TV, Shego put down the phone and abruptly said, "I'm going out."

"Ah, getting close to the enemy, are we? Good good! Remember I need you to get as much sensitive information from her as possible!" Drakken called to Shego as she walked out the door. He could just hear a bored "Yeah, yeah" as the door closed.

XXXXKPXXXX

"Shen!" Kim called her friend over to her usual booth in Bueno Nacho, "That was quick."

"Well, I didn't have far to come. Home is full of excitement though, I could hardly get away," Shen replied sarcastically and sat down opposite the red head. She laughed and they ordered some food. Kim had a salad and Shen, having never been there before and not wanting something too unhealthy, chose the same, trusting Kim's taste. "So, you come here often?" he asked rather awkwardly, not being one for casual conversation.

"Yeah, it's a nice, simple place and Ron basically lives here!" Kim explained, "Do you like it?"

"It's alright, but I prefer to be classy with where I eat, still the atmosphere is good," referring to how the place was lacking customers, so there wasn't much noise. Kim didn't really know what to say to that and wasn't sure if it was sarcastic, so she dug into her salad, while Shen subtly watched her and poked at his own.

"I hear you got in a fight yesterday. What was that about?" Kim asked, finding the silence uncomfortable.

"Ah, yeah, well he deserved it. I'm sick of everyone looking at me like I'm a freak and I don't take crap like that from people, so I smacked him up a little bit. No big." Shen shrugged as if it wasn't anything special or out of the ordinary. He didn't even realise he'd used one of Kim's phrases.

"Shen...he's in hospital for a fractured skull!" she sighed when Shen didn't seem bothered, "Do you enjoy fighting then?"

"Definitely!" he perked up at this and showed immediate interest in the conversation, "It's so exhilarating...but he was hardly a challenge. Not many people are up to my standard," he finished while looking Kim right in the eyes.

"Oh really?" Kim took the remark as a challenge, finding Shen's arrogance amusing.

"Doy! I take it you wish me to prove it?" Shen smiled at Kim with mischief clear in his eyes, which only grew when she nodded, "Very well then, Princess. We'll have to set up a meeting some when."

Princess? Again? Only Shego calls me that. Maybe he just likes the nickname...he also said 'doy' and I only know of Shego saying that. Oh stop being so paranoid! You finally meet a guy you like and you start looking for something bad right away! There's simply nothing going on.

And so the encounter continued without a hitch. They laughed about many things, like what had happened during the week, but also some more serious subjects, including Ron's dislike for Shen. He wasn't bothered by it. He could tell that Ron was just jealous that Kim paid attention to him, which made the plan all the more fun, especially considering Kimmie had no idea. Shego had never backed down from a challenge or a bit of fun and neither would Shen. So let the battle commence.
