What would happen if a Borg cube were in the Aliens' universe and it assimilated a ship. Unknown to them it is infested with Aliens. The ship is taken into the
cube, our battle starts there. This is different since I like having the battles in the same place (the parking lot of my old high school) but putting a number of these species there and letting them fight seemed stupid.
so this is more like an "Out of Their Element" from the Crossover Universe. The Aliens
come out to hunt. The Borg, seeing this unknown species, begin to hunt as well. There are hundreds of Borg drones on one cube and only a few Aliens could have been born on that ship.
Let's say that a few drones boarded the ship to scan the cargo and a few face huggers get them, therefore more aliens. The aliens' claws will
cut through the drones' armour. First Contact showed us that the Borg are vulnerable to matter based weapons. The aliens' speed will help them overcome the slow moving drones.
If the drones happen to do any damage to the aliens, the acid blood will make them think twice. The aliens will basically run
amok, the Borg can do anything. The Borg could trap them with shields but that would just drain their energy. The Borg adapt to situations but they aren't inventive enough to stop them.
