I play a not very nice person who has, on occasion, definitely sat on the villain side of the line. It's been said a few times already and because it is a very, very important thing I will say it again: communication. I've had to coordinate a lot more on the OOC level than I have with any other character. Figuring out directions to take stories and plots, developments and characterization, and the ever important making sure that folks don't get OOC burned by whatever IC stuff goes on.
Also something I have found to be very important to consider: motivations. It's well and good being a jerk, but if your character is a jerk for the sake of being a jerk then it might read more like a gimmick than genuine characterization. Also super important to keep in mind that being a jerk will have its consequences. Another reason why OOC communication is super important. My lady avoids places like, say, the Quicksand because it makes zero sense for someone with a record like hers to just shoot the breeze in so public a place. She's had several attempts at her life and doesn't really have a lot of people she would call friends so really it's been kind of a lonely life for her. But communication and coordination can help you keep things rolling and keep yourself and whoever you RP with involved so you don't end up feeling isolated because, well, your character is a jerk!
