Villain

I think my favorite villain would be the computer from Eagle Eye. The computer, or ARIA, is a defense system for the world in case the president was killed along with every other person in congress. She communicates with two people, and tells them to do certain things, like "Get into the Porsche and drive", or my favorite "Lay flat on the floor now. Your escape is being recalculated." She can connect to any electronic object from a cellphone, to a cargo plane, to a subway tram.  She is a great villain because she can connect to and control anything electronic. Her motivation is to kill the president, leaving an open space for another president, so she can have full access in all electronics, so she can "Protect the Earth". The runner-up president activated the plan coded "Failsafe" so he could become president. ARIA tends to cause a huge mess, like when she crashes a crane into the police department, but she never gets discovered, until the end. ARIA looks like a giant mechanical eye on a moving platform.
