- Kim Possible: "what if... Shego's plasma powers had side effects" (any time in the series)

-.

-old version:

Kim has been showing signs of being extremely ill, when Wade scanned her he found traces of Shego's plasma energy inside her, from their constant battles and getting hit by the blasts, which is killing Kim like radiation poisoning, they try multiple ways to help her but all come up short, they contact Shego, informing her of what is happening and out of respect for Kim's skill's in fighting her she helps them.

By transferring some of her D.N.A along with some cyber implants to replace the damaged tissue in her body, Kim gains the same powers as Shego along with cyber enhancements, making her a plasma-wielding cyborg, Shego stays around to help teach Kim how to use her powers, because of this the two get close and Shego becomes neutral instead of evil, working with team Possible on occasion.

-new version:

Kim was tired, now this wouldn't be odd given her active life, but for a while now she had been feeling really slow and heavy, like she was moving through thick mud, which is why after just an average day of school she was sitting back on the couch like she had just taken 3 missions back to back, she only moved when her twin brothers came running pass and grabbing her Kimmunicator, she jumped up and ran around the room trying to get it back, but that's when she suddenly went dizzy and weak, she stumbled for a few feet, making her brothers stop and watch as she fell down and bounced off the coffee table, the boys cried out and rushed to her side, seeing her unconscious and sweating they shouted for their parents, who came rushing in, Ann went into doctor mode and check her daughter out as the twins explained what happened, she had James call an ambulance while the twins called Wade.

Kim was soon rushed to the hospital and checked out, her vitals were weak, when she woke up hours later and asked what happened she explained she had been feeling weak for a while, thinking she was just stressed, but Ann and Wade said it wasn't, her body was weakening and Wade performed scans, it seems she was exposed to high levels of energy that have seeped into her body and were causing her body to break down, and that is they couldn't find a way of stopping it...she would die.

Kim was kept in the hospital for days, constantly monitored, Wade came in person to help run scans along with Global Justice coming in to help, there were points when her body spasmed and needed to be rushed into operations with Ann helping out, parts of her body had been so damaged and infected by the energy that they needed to be removed. Ron and Rufus came by as often as they could to try and keep her spirits up while everyone tried to figure out how to cure her.

Wade finally found a match to the energy that was inside Kim, it was the same as Shego's, he, along with others, theorized that Kim's constant exposure and hits from Shego's plasma blasts must have left so much residue that Kim's body didn't have time to naturally filter it out so it built up and was now affecting her. the only way to find a cure and save Kim was to get Shego and perform scans and tests to try and make Kim immune to the energy, Ron was quick to go along with Betty Director and Will Du.

They were able to locate Drakken's lair and made their entrance, after beating his henchmen and stopping him from trying to launch a satellite into space they told both him and Shego that they weren't there for his evil plan but for Shego, she wanted to know what they wanted and they explained what was happening to Kim, Shego wasn't too sure about helping but Ron asked if there really wasn't any form of respect she had for Kim and their fights, that she would really let something like this take her out, Shego hated how much the idiot made sense and decided to help if only so she can beat Princess herself.

After returning they got to work, many tests were performed on them both, and tests with their blood, they found that Shego had a natural resistance to her energy because it came with her powers, that it was infused with her D.N.A and the only way to help Kim was to infuse her with Shego's D.N.A to give her the same resistance, but this was taking a lot of time that they didn't have, Kim needed to have more operations and machines to stabilize her, for something this complex they had to call in others to help, DNAmy and the Senior's, Amy for her D.N.A mastery and the Senior's for their resources.

Amy helped because Kim was a fellow Cuddle Buddy lover and Senior helped because he respected the teen hero, they soon had all the tools and equipment needed for what they needed to do next, for they needed to not only infuse her with Shego's D.N.A but also remove the deeply infected areas and replace them with advance cybernetics, such tech being created by the hands of Wade, James and the twins of the days of waiting for any sign of a cure, knowing Kim wouldn't come out of this unscathed given the operations she had already gone through.

It was the most complex and tasking operation to date, the careful removal of infected muscle, parts of organs, and replacement of said areas, while also constantly infusing and injecting new strands of Shego's active D.N.A into the right parts, all took twenty-four straight hours. in the end they needed to remove 39% of Kim's flesh and replace it, from her left eye, her left hand, back of her right forearm, part of her mid-upper back, right section of her waist, left outer thigh, her kneecaps and the bottom half's of both feet. It was hard but they did it, Kim was saved.

It took a few days for her body to settle and Kim to wake up, she was taken aback by her new additions but was thankful so many fought to save her, she was especially surprised by some of her villains helping out, Junior brought her a large vase of flowers and just said life would be boring without her with a slight smile that she returned, Shego said she better not get used to it and that she will be getting her butt whooped by her in the upcoming training she will get when back on her feet, when asked what she meant Shego grabbed her hand and forced her energy into her and suddenly orange flames like Shego's own burst into the palm of the teen's hand, Shego explained that with her D.N.A she has powers like her own and will need training to get them down, Wade also stated with her new cybernetics she can have gadgets built in to help her with missions, further enhancing her capabilities.

Time passed with healing and training as Shego stated, said woman becoming more of a mentor than a villain over time, soon Kim had learned enough for them to part ways, and with Shego stating she better give her a good fight next time they face off, Kim promised her and with that, they went to more rivals than foes.

The villains weren't ready for a cybernetic superpowered Kim Possible and got taken down easier than ever, which led to them powering themselves up with either tech, magic, or altering their own D.N.A. to try and stand a chance of winning, which never worked.

Overall, things went on as normal for all.
