So I plan on applying to a video game company as a character artist. Will that company be able to sue later if I bring out my cartoons that I created before I began working at that company?
I posted this on Yahoo!Answers and would also like your opinion! It's greatly needed...

I plan to apply for a job at a video game company as a character artist. I have years worth of original characters that I have already made. Along with stories, background on them. When I apply for this job, would I need to make it so that the company wouldn't be able to sue me later on for working on my own work? Example: if during the job but on my own time, I draw from what I already have made before working there. Just being my hobby and yet I want something to become of them one day. Would the company be able to claim these drawings and ideas? I recently read about the trouble between Barbie and Bratz. But the creator of Bratz drew the sketches while working at Mattel. My work has already been drawn out. Will I need a patent?
