the predator is as strong as 10 men, but so is the average alien drone. it is possible for an expierienced predator warrior to take out a drone with no more than wrist blades{ keep in mind that this is an expierienced warrior, and it is still no easy task.} but give the predator any other sort of weapon and the alien almost doesent stand a chance. As far as a predator fighting a queen. no contest! the queen would smear him all over the egg chamber. It takes a team of eight predators to detain a queen.. Aliens have their numbers and generational knowledge, and the predators have their technological supiriority with 100 percent deadly combat styles. and humans...well...were gonna loose. But between the aliens and predators it could go either way
