Although there are strong rumors stating that X-Men 3: The Last Stand will be the last X-Men movie, I do agree that it will be the last in this trilogy. Here's hoping for X-Men's 4, 5, and 6, but who should star as the main baddie. Magneto was perfect, however with a possible new team, a new villian should emerge. There are so many to choose from. I have only listed a few.
