If the Yautja discovered a new Mass Relay that was previously unknown, or if they developed ships capable of traversing space faster than those in ME to the point that not having ME Relays didn't hinder them in terms of travel, could the Yautja defeat the various ME races individually?
1.) Which race is superior biologically? How would you rank them?
2.) If instead of Major Dutch Schaeffer (Predator 1) and his men the Predator came across Commander Shepard and his/her crew from Mass Effect 1 would the outcome of the movie have changed plot armor aside?
