Movie: Terminator 2: Judgment Day (1991)

With its creepy chrome skeleton and tireless drive to eliminate human targets, the 800 series cyborg Terminator forever associated with Arnold Schwarzenegger was supremely badass when it debuted in 1984's The Terminator.

Then, in 1991's sequel, James Cameron introduced the T-1000, a more advanced, chameleon-like shape-shifting liquid metal assassin capable of rapid restoration, spot-on physical and vocal mimicry of people as well as objects, liquefaction to squeeze through tight spaces, and the formation of simple tools and weapons using its malleable "skin."

Suddenly the T-800, which was now a good guy sent back in time to protect John Connor, looked like a toaster with a queer Austrian accent. —JM
