The Crusher is a mutated Xenomorph after the nuclear explosion on LV-426. It is not known if the crusher has any relationship with the queen, or if it is solitary. It is only known that the crusher has a great head shield which cannot be penetrated by bullets and serves to push or smash enemies. The Crusher also has a brownish tone for its skin. It walks on four feet and sometimes climbs along low walls. Its speed is very fast and it has the size of a Praetorian. The crusher's best known weakness is that its heavy armor plating only protects its crested head; damage incurred to other portions of its body will still cause injury as normal.
