Despite being apex predators, Xenomorphs in the Alien franchise have many weaknesses, and Alien: Earth seemingly confirmed another one in its second episode. With this rare weakness added to the canon, there are now more ways to take on the mighty Xenomorphs.
Here is a list of every weakness the Xenomorphs have in the Alien franchise.
List of all weaknesses of Xenomorphs from Alien: Earth and before
Electricity
Electricity is the latest weakness of the Xenomorph revealed in the recent Alien: Earth episode. Apart from the weaknesses shown earlier in the films, this is another factor that can subdue the extraterrestrial creature.
Alien: Romulus previously teased electricity as a weakness. The new series confirmed that electricity can temporarily, or in large quantities, permanently disable the Xenomorph. Morrow subdued the alien with a prolonged bolt of electricity from a taser in the second episode of Alien: Earth.
Bullets
Despite being very strong, the Xenomorphs are not bulletproof. However, using bullets against them can still be complicated, as their blood is acidic. As seen in previous movies, their blood can melt through human skin and even spacecraft, making the use of bullets or explosives risky when facing this creature.
Space
The relatively safer weakness of the apex predator, ejecting the creatures into space, has been one of the more reliable methods of killing them in the Alien franchise. Alien and Aliens focused on this method. Though Alien: Romulus depicted how space may not be enough to completely kill off every Xenomorph, it remains among the most effective ways of eliminating the creature without collateral damage.
Extreme Temperatures
Extreme temperatures have also been a recurring method in the Alien franchise for killing Xenomorphs. From flamethrowers to extreme thermal heat, Xenomorphs struggle to survive in such conditions.
Alien 3 had a memorable sequence where the prisoners tried to drown the Xenomorph hybrid in molten lead. Though it did not kill the creature immediately, the use of cold water afterward caused thermal shock that killed the Xenomorph. Alien: Resurrection also showed Xenomorphs being controlled in captivity with extreme cold.
The first two episodes of Alien: Earth are now streaming on Hulu.
