It seems to me that the toughest bad guy in any movie that could not lose to anything is the T-1000 from terminator 2. Can anyone think of anything that could take it? The only way it lost to Arnold was because he fell in a pit of hot lava. Without hot lava, how would you kill it? This is LAME, I know, but after reading Predator vs. Alien in the Fantasy matchup forum, I was forced to think of it.
