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