Terminator vs Predator vs Alien

im not sure but i think they made a comic book about this

It definately depends on how many there are but if there is one of each the would be killed by the alien because predators see heat and aliens are coldblooded. The terminator would most likely kill the alien especially the T-1000 or the T-1000000.

But the predator is my favorite so i don't know

they did make a comic some time back. Id say fully armed a Predator.
unarmed? the Queen or T-1000

and Pedator is my fav as well

If the human can beat the Predator. Why cant the Terminator?

What about Robocop?
