Sailor Moon Villainess to be captured

So I recently put up a poll in the group about continuing my An Experimental Afternoon story - one where Ami invents a 'uniform simulator' to try and understand the Senshi's powers better, only to find she's created a body-control device. Some experimentation with Usagi and Makoto leads to a revelation of Ami's fantasies of sexual submission.

The poll was to help me work out some ideas I had of what to do after Ami talks to Michiru - Sailor Neptune - to try and work out her feelings.

After only about a day of polling - so take this with a grain of salt - one option that seems to be quite popular is having the pair use this technology to seize control of a villainess.

Now, this is a big field of possibilities. Sailor Moon has an enormous cast of female enemies from dark overlords to expendable monsters of the day. Plus, there is nothing that rules out original foes or characters from other sources.

So I thought I would ask here, as the forum allows for easier discussion: For a situation where a villainess is forced into the service of a heroine, what would be good qualities for that enemy to have? If you would like to suggest a character, that's fine, but I'm more generally interested in what type of person would make for interesting story in a situation of this type.

And I supposed the associated question is: What purpose would that character be put to?

Thanks in advance.

well she should be tough to break and possibly try to at several points to seize control of ami and neptune.
arrogance and being extremely self confident would also be some requirements

Manipulation should be a must unless you just want a story with the villainess being brought down a peg(which if you where, the best route would definitely be comedic for me, but that's just me). To achieve this end they should be able to act humble, like a servant, in order to achieve their main goal of either trickery of getting Ami into the suit, mental dominance of the submissive Ami, or corruption of Ami.

As for services, maid would be something, doing good for soceity, or if you take one with some hypnotic powers(Giwaku for example), you could use her to convert more enemies to the light side, or just to servitude.

Though truthfully I must confess that I have not gotten around to reading your first story, so these are pretty much outside speculations and suggestions.

link to your previous story would be helpful too

Aaah. I though I'd put that on the yahoo group already, but it looks like I did not.

It is up now, the link is http://f1.grp.yahoofs.com/v1/0CLqTxgrZbqt7tDaS2YvOys25jptoXu83vqnsfQY9BhoUcAJxWdpvgWwTb6ydedpLWoYgExmwHOy-Q38DYfX26rHPvPl6WY/Stories/An%20Experimental%20Afternoon.txt

Okay, votes on the poll dried up after about a week, so I closed it.

As for villainesses to be captured and controlled, I was thinking it might be an idea for Berthier to pick up some new power and need correcting again. Also allows Michiru to add to her water girl harem. Berthier is also smart, tactical, ambitious and fashionable. A good addition to the 'set'.
