Terminator vs RoboCop

Terminator vs RoboCop.

For what is essentially a fan-made mishmash thing, these are extremely well done and totally badass.

(EDIT)

From the same creators of the above:

Neo vs RoboCop. This one isn't quite as good as the other two, and the cameo appearance is just nonsensical (even more so than the cameo that was in the first Terminator vs RoboCop video).

Schwarzenegger vs Stallone. This one's pretty good. I particularly like the bit where they're both standing in the open about ten feet from each other blasting away with machine guns for about a minute straight. :) You'll see what I mean if you get that far.

Also, from rabbitucker, Captain Harlock vs Han Solo (scroll down as there's some other stuff above it). Interesting ending to this one. I haven't watched the Harlock vs the Empire one yet though. Currently downloading it.Will download later, because it's dl-ing at a snail's pace.
