Zombies (or other such horrors) combined with supers can get really fearsome! In DC’s “DCeased” comic, the Flash got infected by that comic’s version of zombies and the results were about as bad as you would expect. A good portion of the story takes place off planet once that happened!
Can the Xenomorphs exert control over the host? (I honestly can’t recall.) Even if they don’t retain traits of the host after they’re born, having control over that kind of power could make it really easy to obtain new hosts to infest.
