Identity Thief
Chapter 4
Museum Melee

Kigo, sporting the full Kim look ever since she released her grip on the ceiling, glared at her half mother with her evil, yellow, reptilian eyes which immerge now when she loses control of her emotions. Shego, half disappointed Kigo wasn't her childhood employer and half confused to see something in the image of Kim Possible viciously decapitate a cheap animatronic robot thinking it was her, cautiously stepped forward, her hands readied with their signature green pulsing glow. "Well, aren't you a clever freak show," Shego taunted. "You lure me out here knowing I would love to get Tsubohachi for the shit he put me through and you jump me right before I steal the hat."

Kigo snarled and back flipped to the top of the glass display case of the aforementioned hat. "But Tsubohachi would be the kind of asshole who would get you before the agreed meeting time so you used Drakken's dummy robot. Shit, why didn't I think of that?" she asked angrily.

"Alright then, who are you? I know you're not Kim Possible; she doesn't fight to kill and her eyes aren't yellow," Shego said, taking her final step into the display room.

Kigo grinned and turned her back to Kigo. "Well, that's a valid question. Maybe I should show you who I really am." With that, Kigo began, to Shego's surprise, to strip off the clothes she stole from Kim's room by ripping them apart at the seams until there was a pile of ripped clothes on the floor and a perfect duplicate of Kim's uncovered backside facing Shego. This strange action was soon explained as Kigo's size increased slightly, her skin paled to a familiar color, her hair grew and changed color, even her skin changed to appear as a form fitting jumpsuit of black and gray. As she turned around, Shego stepped back and growled in anger; this false Kim was now in her own image. "I'm your dark side."

As Kigo jumped back down to the ground, Shego took a fighting stance. "This world can barely handle this Shego; I'll do it a favor and get rid of the excess waste."

Kigo grinned and made a mirror image stance of her genetic parent. "I was thinking the same thing," she said, before she took flight toward Shego with a kick. Shego ducked and spun around with a long arched kick only to have it grabbed in mid-air. "You suck mom!"

Shego was thrown down the museum hallway and she barely rolled to safety behind an old suit of European armor when she saw Kigo's rain of black energy bursts began to hail down on her. "Shit, why is she so good?" she asked herself. "I can't react that quickly." When the torment of black energy stopped, Shego rolled out and tried to attack Shego to see she was gone. "Shit, where did she go?"

Kigo dropped down from the ceiling but Shego stepped back in time and began to unleash a flurry of moves at her full strength. Kigo predicted every move, dodging, weaving, and swatting Shego's limbs off target with ease. When Kigo when on the offensive, Shego did her best to defend herself as well but was being hit with quick jabs and short kicks. In desperation, she jumped over one of Kigo's kicks and delivered a spinning kick right to Kigo's face. This made Kigo drop to one knee and when Shego tried to end it quick with a powered up doubled fisted hammer drop to Kigo's head, Kigo threw a powerful black lighted punch to Shego's midsection. This sent Shego flying back until she painfully crashed into a wall, a section of her jumpsuit burnt from Kigo's plasma fist. Kigo rushed forward before Shego could recover and delivered a hard kick to her head, knocking her flat on her face in pain. "See, I have your strength and Kim's skills. Mix that with my willingness to kill, you never stood a chance."

As Kigo walked toward Shego to finish it off, the original article stopped playing possum and quickly twisted her body toward Kigo before firing a double shot of energy bolts from her hands to Kigo's gut. The sudden attack sent Kigo reeling back, landing ass flat on the floor. Shego knew that if she kept fighting normally, she would be at a disadvantage since obviously this freak show was made to be stronger then her. So Shego quickly grabbed the suit of armor she was hiding behind earlier and chucked it to Kigo before she could get up off the floor. "Hey, if it makes you feel any better, I'm willing to kill you too."

Sure that last attack was enough to render Kigo helpless, she walked forward and cautiously began to move the armor aside. Suddenly, Kigo's hand grasped Shego's throat and lifted her into the air as she stood up from the metallic rubble. "Your soul is willing, but you're too damn weak!" she declared. Shego tried to retaliate but Kigo pulled back and hurled Shego to the wall head first. Shego was on the verge of passing out; that last blow opened a small wound on her head and blood was now starting to soak into her long, flowing, raven hair. Kigo, sadistically excited with the knowledge that Shego has reached the end of her rope, began to pummel once proud criminal mercilessly until she let out a cough that showered blood on Kigo's feet. "That's enough for now," she said with an evil grin, taking hold of Shego's head and chin. "Now to hear my favorite bodily noise; SNAP!"

Before Kigo could continue with her cruel act, a sudden hard impact to her side pushed her away from Shego and sent her tumbling down to another corridor of the museum. Kigo growled and looked to see the heroic figure of a certain red head in a black mid-drift shirt and cargo pants. "It's over Kigo," Kim said with a determined face.

"I don't need this, I was here kill Shego; your time will come soon enough, cheerleader!" she hissed.

"Sorry, but even Shego doesn't deserve this and you have to be destroyed since you're a freak of nature."

"Destroy this bitch!" Kigo spat, giving her the finger.

"Cute," Kim said indifferently. When Kigo rushed forward to attack, Kim quickly aimed her arm out to Kigo and shot from her wrist a brown blob. The blob hit Kigo's arm, making it stick to the wall. Kigo hissed in anger, trying to pull free from the sticky brown web of goop. "Don't worry, it'll be over soon" Kim said, pulling out a bottle of Dr Pepper. (SHAMELESS PRODUCT PLACEMENT!!!)

Kim shook up the bottle and sprayed its contents over Kigo's body. Instead of melting into a puddle of green ooze, Kigo simply shrunk in disgust and shook the beverage off her free arm. "Why the hell did you do that?" she asked.

Kim raised an eyebrow, she was at a lost for words. "You should have been broken down into your basic elements after that. The soda trick worked on Drakken's clones just fine."

Kigo smirked smugly despite being stuck to the wall. "I'm in a whole new league from those cheap knock offs. One good thing I'll say about dad is that he's a better inventor that Drakken could ever be."

Before Kim could act, Shego, bleeding from the mouth, part of her hair was flatten down from the blood coming out from her head, her body limp from the beating she took yet her eyes blazed with a green flame of determination as well as her hands, pushed her aside as she walked toward Kigo. "Fine by me," she said, trying to convince herself that her injuries were not bothering her. "Its pay back time," she said with an evil grin, cracking her glowing knuckles.

All of a sudden, there was a panicked scream and a crash of glass from overhead. When all 3 girls looked up, they saw Ron Stoppable, dressed in his mission clothes, dangling from his grappling rope. "Aw man, this is supposed to be my time to save the day," he whined.

During the confusion, Kigo, using another skill granted to her from her reptilian DNA, ripped her own arm off her body and ran under Ron. "Well, you certainly are my hero spaz," she said mockingly. "I'll remember to kill you quickly the next time we meet!" The other two girls tried to stop her but Kigo leapt straight up through the broken skyline window. "Here's something to remember me by!"

She cut the rope and Ron plummeted down to earth. To Kim's surprise, it was Shego who rushed forward and caught him before he landed. Ron looked up at Shego, confused at first, then smiled innocently. Shego rolled her eyes and dropped him like a rock. "I just wanted to make sure you got hurt before Kimmie could save you," she said. But her battle with Kigo had left her to the breaking point, she could no longer stand on her own strength and so she collapsed.

It was near midnight when Shego awoke on the couch in the living room of the Possible household, her bruises and injuries tended for carefully and bandaged, her jumpsuit laid out under a ceiling fan to dry after having the blood cleaned off it and the rips sewn shut. When she tried to sit up, a jab of pain from her midsection forced her back with a groan. She almost jumped when a soft hand on her shoulder gently pushed her back down on the couch. "You shouldn't move," said Marsha Possible.

Shego looked away and grunted. "I don't like pity," she said.

"You're in no condition to argue," she said, sitting down on a chair next to the couch. "Luckily I took some general first aid courses in college before I became a brain surgeon but I might be rusty. Are the bandages tight enough?"

Shego wouldn't look her in the face. "You know who I am, don't you?"

"Shego, Kimmie's arch-nemesis's assistant right? Don't worry, we're not turning you into the police, Kimmie just couldn't leave you there. You had quite a tussle in that museum; it's amazing how you can push yourself so far."

Shego growled. "Is everyone in this damn family so bloody upbeat or are you just trying to make me puke blood?"

"Well, I don't care what you say. As a doctor, it's my duty to make sure you recover while maintaining a positive bedside manner. Besides, I want to get to know you."

"Why?"

"To see if I can get you to stop living a life of crime. You know, an honest life is much more rewarding; a job, a house, a family, your own children."

"I hate children, they're loud and obnoxious."

"Why do you feel the need to push people away?"

"I thought you said you were a brain surgeon. Why are you babbling like you're some kind of shrink?"

"No reason, idle chitchat I guess. I really think you're fascinating since you're so mysterious."

Shego slowly rolled so she was facing the ceiling and closed her eyes smiling. "Well, I guess I can break the ice a little since you stopped me from having gangrene."

Meanwhile, back in Kim's room, Kim conversed with Wade while Ron stared unceasingly at Kigo's severed arm. Now away from its mistress, the arm was now a light, pale green color, the skin now scales, the fingers now sporting sharp black claws, truly, it was a reptile's arm. "This is just sick and wrong," he said to Rufus who nodded in agreement. "Hey Kim, how did you get in the museum before I did?"

Kim turned to Ron. "That ride Wade setup really knew how to haul ass. Besides, it was probably for the best that you didn't face Kigo alone, you saw what happened to Shego," she said.

"Yeah, it's kind of funny she's in you're living room right now though. Especially what she said to you before she escaped Drakken's lair."

Kim growled and threw a Cuddle Buddy at Ron. "Never bring that up again! I hate myself for telling you in the first place."

Ron held his hands up defensively and picked up the Cuddle Buddy. "Ok, Ok, so now what?"

Wade interjected to answer Ron's question. "Unfortunately this DNA sample is just what I was afraid of; Kigo, though composed of several complex beings in one body, is genetically stable. The soda method won't work, no matter how much you use but there is a way," he said.

Kim turned to the computer. "What you got for me Wade?"

"There's a genetic destabilizer in the research center where their holding Gill that might be able to break apart Kigo's DNA structure like soda did with Drakken's clones."

Kim smiled. "When can you get it here?" she asked.

"By morning if I ask them right now."

"Please and thank you."

Kigo walked the streets of Middleton, not a strip of clothing on her, exhausted from losing her arm and in her true form. She was defeated for now, but what bothered her most was Shego. Kigo had her right where she wanted her until Kim butted in. Then to have Shego, approach her with that kind of strength and courage nearly on the verge of death almost scared her. "She's just a stubborn bitch," she hissed to herself. "If I would've stopped playing around for two seconds I'd have her head as a coffee mug and her body to feed some guard dogs. And that Kim Possible, she couldn't have done shit without her gadgets!" She was on the verge of losing it until she reached her destination. Then her scowl turned to a grin and her tongue hissed happily through her teeth. "Here we are, 335 NE Main." Kigo turned her body into Kim's minus the arm and clothes and went around the side of the house where she jumped up and through an open window on the second floor. "Your dream girl is here, Josh Mankey!"
