Welcome, dear readers and writers. After rediscovering Kim Possible and falling in love with the Kim/Ron coupling, I wanted to write a Kim Possible FanFic. I wondered, what's Kim and Ron been up to these since graduation? After reading some old comics on SHIELD, I decided on combining the two universes and came up with this theory. Now, I present to you this story and hope you all enjoy reading it as much as I enjoy writing it.

REBORN DARK PHOENIX PROUDLY PRESENTS

KIM POSSIBLE: AGENT OF SHIELD

Prologue: Unstoppable

*Remote SHIELD scientific/weapons storage research base; Fiji. Night. Location known to only a select group of SHIELD personnel*

The night was quiet, except for the constant chirp of crickets and other insect wildlife in the jungle brush. The guards, heavily armed as they are, were suffocating in the island heat. Clothed with above standard SHIELD Kevlar uniforms and bulletproof vests, the circulation of air through their body pores was minimal at best. The five of them didn't understand why they had to be outside keeping watch near the large adamantium-laced metal gates, while the other guards were inside the post tower, where there was air conditioning, snacks…hell, even a TV and the Super Bowl was on tonight, too.

Little did they know that they wouldn't have to worry about such details after tonight.

"Damn, I wish we were taking the inside duty. I'd give anything for Lorenzo's shift on monitor duty," one agent said.

"Quit complaining, mon ami," another agent said as she leaned against the gate, resting her assault rifle on her leg. "Qu'est-ce que je donnerais pour la climatisation."

"Enough with the French, Celeste," the squad leader smirked as he walked forward, closer to the jungle. "If you want to say you want AC, just say it."

"Fine, mon capitan-I want le AC."

"Did you just tell Alec not to complain?" the sniper agent asked from his position up in the tree near the gates. "And now you're complaining, too?"

"You all talk too much," the last agent mumbled as he chewed on his cigar.

"Oh c'mon Vladmir, cheer up," the squad leader chuckled as he checked the radar on his hand held scanner; again, as it was five minutes ago, and 20 minutes ago, and the last three years, there was nothing on the radar. "Actually, I could go for a beer about now."

"I'm sure they have a bunch of beer inside," the sniper said. He again scanned the jungle with his rifle scope, and again like always, there was nothing. "How much y'all wanna bet that if we ask, they'll hold out on us?"

"I'll take some of that action," Agent Celeste replied.

"Gate Squad, you know we can hear you, right?" a female voice chuckled through their comm links. "If you want some beer, all you need to do is ask. Oh, and the Patriots just landed another touchdown."

"Merde!" Celeste muttered.

"You're from Haiti, since when you love American football?" Vladmir smirked.

"Post command, all clear out here…again," the leader said with his own smirk as he walked back to his team.

"Yeah, we know, Lieutenant, we can see on our radars there nothing out there."

"Then either bring out the beer or wait for our next call in."

THUNK!

A sniper rifle suddenly fell from the tree next to the gate, startling every one. It was the same rifle the sniper agent used. A sudden rustle was heard in the leaves above, and the team raced to the tree. "Trevor, you ok up there?!" Alec shouted up to the tree. They were all shocked to see a gloved hand slip through the foliage and come into view. The hand remained unmoved and stiff. It took them a minute to see the slow trickle of blood descending from the fingers.

"Mon Dieu, he is dead!" Celeste gasped.

"Post command," the captain shouted into his comm as he grabbed his assault rifle, the rest of the agents doing so as well. "We got a situation! Unknown assailant just came out of nowhere, and they just killed Trevor! Repeat, unidentified assailant is in the vicinity, we do not have visual!"

Static.

"They've cut the-!" Vladmir began to yell out before a dagger suddenly was thrown out of nowhere into his jugular, causing an eruption of blood as the agent fell to his knees, grasping at his fatal wound as he died in front of his teammates. Celeste screamed in horror.

"Vladmir!" Alec yelled as he ran over to his fallen agent. "He's…he's dead!"

"Oh my God!" Celeste said with fear as she repeatedly aimed her assault rifle at the vegetation. "What the hell is goin-!" She was interrupted by a silenced bullet to her head from an unknown position, sending her body staggering a few feet until she fell onto the floor, dead, as blood oozed from the bullet hole. Alec didn't even get a chance to react as he was met with the same fate, his dead body falling onto the dead body of Vladmir.

Only the squad leader remained.

"Dammit, Post Command, respond!" he yelled into his comm as he desperately aimed his assault rifle at random points at the jungle. All he got in response was static in his ear. Before he could do anything else, however, he felt two powerful hands grab his head, and his life was instantly ended as they snapped his neck, killing him.

"No help's coming for you, pal," the assailant sneered as he walked over to the dead Russian agent and took his blade out of the man's neck. Checking to see that his sidearm was still silenced, the assailant then did a remarkable back flip over the gates and proceeded to his objective. His virus would keep the cameras all over the base on loop for the next minute; he had until then to complete the next part of his plan.

Too easy.

*50 seconds later*

"Um…guys?" Agent Lorenzo said as he looked more closely at the security monitors. "I think we got something over here."

"I'm sure it's nothing Lorenzo," the captain said with ease as she and the other agents continued watching the Super Bowl. "Oh, yeah, touchdown again!"

"Cap, I'm serious…I think this is on a loop sequence."

"Lorenzo, it's nothing," another agent said as he drank some more beer. "Give it a rest and come watch the game, mate."

"Guys, I'm serious, I think something is really wrong with this-!"

Before he could finish the sentence, the air vent grate on the ceiling suddenly fell to the ground with a bang, followed by a series of gas-filled vials that cracked open upon crashing onto the ground. Instantly, the room was filled with a hazy gas that in just a few seconds enticed unnatural coughing and wheezing amongst the seven SHIELD agents. Within 30 seconds, all their lungs collapsed in failure and they each fell onto the floor, dead. A minute passed before a well-built male wearing all black clothing-kevlar armor uniform, boots, leg side arm holsters, fingerless gloves, a combat utility belt and knife sheathes on his arms-descended into the room on a rope, a gas mask on his face. He had dirty blonde hair and black shades covering his eyes, which actually served as an all-purpose visor and detector. Upon touching the ground, he went for the monitors and finding a few USB ports, he installed drives in each of them, uploading multiple viruses and effectively crippling the base's security system. All cameras and alarms, unless activated manually, were now useless.

Step 2 was complete; now for the hardest part-obtaining the target.

Making for the door, the black-clad intruder suddenly noticed the TV. "Oh, cool, the Patriots are winning." After that, he exited the monitor room.

He made his way through the base, his shades serving to see through walls and alert him of any guards and agents coming his way. He was moving at a rather slow pace, something his master really didn't smile upon; he preferred moving at this pace though. By his training, he was mostly an infiltrator and scrapper type of spy/agent/assassin. He preferred stealth, agility, precision and well placed strikes over brute force and open assault.

Of course, he also liked to get his hands dirty. He occasionally would sneak up on a pair of patrolling agents and snap their necks.

After 15 minutes of stealthily moving through the base, the intruder came across a forked hallway; this was in the plans he had of the base, of course, and he wasn't worried. Taking the handheld scanner from his belt, he brought up a 3D map of the base complex. Finding his current location on the map, he scanned the blueprints and found that the most efficient and stealthy way to get to the target was to the hallway on the left. From there, after reaching the target, there was an air duct in the adjacent hallway from the target's room from which he could sneak out of the complex and return to the jungle, and SHIELD wouldn't be the wiser. If all went accordingly as he had planned, the base personnel wouldn't realize he had been there until 16 hours from now. Setting a path for himself, and checking on his handheld that the virus was still messing with the base security systems, the intruder started walking to the left hallway…

Only to be seen by a lone patrolling agent that was also coming out of the hallway. For a few seconds of surprise, the two individuals stared at each other. But the intruder, thanks to years of training and conditioning, quickly regained his senses and knew what to do.

"Excuse me, sir, I think I'm lost; can you point me to the little agent's room?"

"What the-?! Intruder!" the agent yelled out as he went for his ear piece. Unfortunately, he was unable to use it as the intruder quickly pressed a button on his scanner, sending a short EMP pulse out and rendering the SHIELD agent's comm useless.

"Let's keep this between us, pal," the intruder smirked as he took out his combat knife. Without a sound, he lunged at the agent, his blade at the ready and the knowledge to use it to back him up. But SHIELD agents are among the best combatants in the world, and despite being caught off guard, the agent knew how to hold his ground in a fight. He was staggered by the impact of the intruder's lunge but quickly made up for it as he lashed out a fist in an uppercut, barely missing his opponent but giving him the distance he needed to assess the situation and get a look over at his opponent. "Finally, an opponent who can fight back," the intruder smirked as he sheathed his knife, no longer wanting to use it, and he took up a fighter's stance. After a few seconds of circling each other, the two men charged at each other. The intruder feigned a right hook and when the agent made to block it, he was met with an uppercut to the chin; the agent wasn't out that easily, though, and retaliated with a sweep kick and a haymaker to follow up, surprising the intruder as he made impact with his attack. As soon as the intruder crashed onto the ground, however, he instantly jumped back up and fired a jumping roundhouse kick, sending the agent flying a few feet back. The hit rattled him-HARD. Struggling to get up, he felt like a few ribs were his opponent had hit him had cracked, maybe even broke…his head was starting to ring now, and he felt a bit dazed from the hit. But he refused to give up; he had to hold out until back-up arrived and this intruder was down and being interrogated. Looking up, he saw the intruder jumping at him, ready to land with an axe kick, but the agent dodged at the last second and lashed back with a snap kick, sending the intruder's momentarily unbalanced from sprawling onto the ground. The agent then made to do like wrestling and pile dived at him, only for the intruder to roll out of the way very quickly and grab him by the neck with his legs and grabs his flailing arm.

"You tried, I'll give you that," the intruder smirked as he applied pressure to the agent's wrist joints. "But it takes more than that to beat me." At that, the intruder snapped the agent's wrist, breaking it and enticing a pitiful scream from his mouth that could barely be heard and ended abruptly when the intruder expertly adjusted his legs and snapped the agent's neck. The intruder got up and looked at the dead body. "Can't beat the unstoppable." He checked his watch; this little dance had cost him a precious 22 seconds. He'd need to avoid any and all guards now. With a silent dash, he raced down the hallway, the scanner in his hand to guide him to where he had to go.

Two minutes later, he reached the room where his target would be. Stopping just before where the hallway ended and bonded with a large room, the intruder activated the infrared vision on his shades. He looked at the wall and with the enhanced heat motion sensors also installed in his shades, he could make out seven heavily armed agents guarding a 7ft by 10ft metal vault door. Behind that door lay his target, the entire reason he was even here in the first place. Reaching into his combat utility belt, the intruder calculated the angle necessary to fire his projectile as he took out his gas mask and two small circular vials filled with the same colored gas he had used to kill the agents in the security monitor room. After he put on the gas mask, he waited an additional two seconds before throwing the vials into the room, straight for the seven agents; two seconds later, the intruder walked into the room, his sidearm at the ready, but seeing the agents suffocating due to the gaseous poison and unable to even try and stop him, the intruder smirked to himself and holstered his weapon. By the time the gas has dissipated, the agents were dead and he had connected his scanner into the passcode keypad, hacking the encrypted code to enter the room guarded by the vault door and get to the target. In just 15 seconds, the encryption was cracked and the vault door slowly opened. With a smirk, the intruder said to himself, "Again, too easy," and walked into the room…

And was confronted with four more heavily armed SHIELD agents…in a second room serving as a second buffer, complete with a second vault gate.

This was not in the blueprints.

"Well…damn."

"Sound the alarm!" one of the agent said as she fired her assault rifle and began launching a bombardment of bullets at the intruder; he was able to dodged the rounds, but just barely as he was caught by complete surprise. He saw another agent dash for an alarm switch near the second vault gate. He instantly saw that that alarm was not connected to the base's main security system, but rather on a whole other back-up system, and if the alarm was activated, the whole base would know what was going on, and he couldn't have that. And so, as he leaped out of the way of the bullets, he flung two knives-one at the shooter, the blade embedding into her hand as she screamed in pain and dropped the rifle; the second blade embedded itself directly into the other agent's neck, severing his artery completely and making him collapse just inches away from the alarm, bleeding out from the vicious wound in his neck. The intruder to a second to sigh; he was still safe.

WAH WAH WAH WAH WAH WHA

"Oh, come on!" he roared as he snapped back up to his feet, his side arms in his hands. Scanning the room, he saw that there were in fact TWO alarm switches, and as he had killed the agent heading for the first alarm switch, he had completely missed another agent dashing for the second alarm and activating it. Now, as the intruder heard the blaring alarms echoing across the base, he knew it'd be three minutes tops before he was swarmed by heavily armed tactical strike teams searching for his head. He turned his attention to the other three agents, who were now aiming their assault rifles and, in the case of the agent who had been hit with his knife, sidearm. "That was completely unnecessary," the intruder snarled as he cocked his guns. "And I don't handle unnecessary complications that well."

"Take him down," the bleeding agent said with anger and the three agents fired their weapons. The intruder easily dodged their attacks with uncanny agility and athletic skill, jumping and sliding and racing with unimaginable grace and reflex as he raced towards the agents, a sneer on his face and a murderous glint in his eye. He was conditioned and trained so that he couldn't be hit by bullets and be able to easily dodged them. These agents were wasting their time and last minutes doing so. As he leapt above their bullets in a twirling motion, he fired his guns three times, each time hitting an agent directly in the head each time, instantly killing them. The intruder landed on the floor with grace and precision as the bodies of the agents collapsed onto the ground.

A minute left. He had to give it to SHIELD; adding an extra buffer room not on the blueprints was actually a smart idea.

Quickly, he connected the scanner to the second passcode keypad, and within another 12 seconds he had cracked the encryption and opened the vault door. Dashing inside, he used his scanner's advanced technology to close the vault gates and seal himself in, the gates closing just as he saw SHIELD strike teams enter the room. With a smirk, he waved at the shocked agents as the gates closed with a loud bang.

Making sure that they wouldn't be coming in after him any time soon, thanks to the 10 inch thick titanium/adamantium alloy gate, the intruder turned around. There, finally, lay his target.

The blonde intruder walked up to the large technological wonder before him; a machine with multiple thick coiled wires and apparatuses blinking various colored lights. The machine pulsated with the power that the energy source gave it. A nearby laptop confirmed that the machine wasn't active. Walking up to the machine, the intruder gazed at the technology before reaching for the middle bit of the machine, a large hole with spiked projectiles used for data and energy gathering. There, he grabbed a handle and pulled up, revealing a glass and metallic cylindrical case, and inside the case was a blue pulsating cube.

He smiled; torturing the SHIELD agent he had captured days ago proved to be not only fun but useful. Their intel was right.

"HYRDA X to Strucker," the intruder said into his ear piece comm as he looked over the prize. "Intel has proven correct; SHIELD's artificial Tesseract is in my possession."

"Excellent work, my boy," a voice replied. "No complications, I presume?"

"Not initially, but there was an extra buffer room not on the blueprints and an alarm was triggered. Nothing I couldn't handle. The Tesseract will be in your possession in 6 hours' time."

"You serve me well, my boy. I knew you were the one for this job. Be at the rendezvous point as planned."

"Yes, Baron Strucker."

"Hail HYDRA!" the voice said with a sinister feel to it as the link went dead. The intruder turned to the vault door, from which could be heard the sound of thumping as SHIELD agents tried to force open the gate vaults. The intruder smirked as he walked over to where he had sealed the gates. Placing a small grenade there, he then walked back to where he was previously standing and readied himself and his two side arms for battle. They wanted to come inside so badly?

"Hail HYDRA."

He'd let them in himself…and they'd be in for a surprise.

"Boo-yah."
