The Alien creature born from a Predator is commonly called Predalien. From what is known the host defines most of the Alien's characteristics. For instance the common Alien Drone from a Human is tall, has a vertical posture and isn't very fast nor strong. On the other side the resulting Alien from a Dog stands in four feet and is very fast.
So it's no surprise that the Predalien is usually very strong, possesses a great strength and can jump very long distances.
The first appearance of the Predalien creature was in a picture from Dave Dorman, a famous illustrator.
More recently the Predalien was introduced in a Video Game called Aliens Vs Predator 2.
In the ending scene of Alien vs Predator movie we see the fist cinematographic appearance of a prealien chestburster.
