Karen Plankton, your newly married wife.

Here is your new wife, after some very heated back and forth between Sheldon Plankton and Karen which led to them having been separated. As she just wanted to help her ex-husband to achieve his dream but soon lead to her wanting to stop his nonsense and live without scheming or plotting world domination. But with Sheldon Plankton old habits die hard and he remained steadfast on stealing the Krabby Patty formula with or without Karen. So Karen decided to distance herself from Bikini Bottom as far as possible resulting with her on mainland and later adopting her new body from an abandoned android body from a failed start up tech business. Which lead her to you whether or not you aided in her updating and upgrading her body or simply finding her afterwards is entirely up to you.

In this AU of Spongebob Squarepants, of my own making as far as I'm concerned, Sheldon Plankton only focused on his world domination and only viewing Karen as just another means to steal the Krabby Formula. Not the love that resulted in her creation or the love that had made Sheldon's life realize the importance of his partner. So if you are wondering she is the average relative height of a female she just found the bigger body in the back alley of a failed tech business that attempted to make artificial partners only to be met with severe backlash from concerned individuals. And some backers backing out from the backlash.
