Mystique, although I would not call her a villain. To be fair, you have two flavors of Mystique. When she is working for Magneto, Mr. Sinister, or the Hellfire Club, she is the best covert ops agent you can get. She can walk into any building in the world, no matter how tight the security is, and get what she is after. She can also act like other people with flawless precision.
When she does things on her own, however, her agendas involve her kids in some form. This sounds weird considering how she's treated Rogue and Nightcrawler over the years, but even bad parents still want to do right by their kids. When she is working for someone else and if Nightcrawler or Rogue are in danger, she turns on her employers to get her kids out of harm's way. When she poses as someone not related to a job, it usually as a friend of Rogues or Nightcrawlers. But that does not mean she will not betray her kids if that is a part of someone else's plan. She will not do any real harm to them in the process.
When her third son, Graydon Creed was murdered, her agenda was to find out who did it and how to best make them pay.
