As Seen In: Terminator 2: Judgement Day (1991)

How a being made of liquid metal is a robot is beyond us, but that's what he's pegged as. With no power supply, an ability to withstand multiple bullet wounds, and the ability to morph into any object or being he wants, the T-1000 is still the ultimate terminator in our eyes. Yeah, he was evil, but he was just doing his job. We can't knock him for that, can we?
