Fan Theories About Movie Monsters That Actually Make Sense

List Rules
Vote up the most plausible fan theories about movie monsters.

In horror and fantasy films, movie monsters are prevalent. Many of these monsters go on to be just as or even more iconic than the films that feature them, and now, Redditors are exposing movie monster fan theories that are actually quite plausible. 

Some of these monster theories are a bit more "out there" than others. However, all of them have the capacity to make even the most hardened of viewers drop their jaw, even if it's just a tiny little bit.

    Xenomorphs Are Designed As The Perfect Living Weapon In The 'Alien' Franchise

    From Redditor u/-Demos-:

    Alien Theory: The Xenomorphs' overly complicated reproduction method was intentionally designed to make them the perfect living weapon.

    In nature, animals evolve to adapt themselves to the surrounding environment, and there are a lot of different environments in a single planet, and even more in different planets and galaxies, so my theory is that the Xenomorph was designed as the perfect adaptive killing machine, by giving it a reproduction system which allows it to copy the evolutionary adaptations of the living creatures native to any planet they are invading, and use those specific adaptations to become the Apex Predator of that planet's ecosystem.

    Instead of trying to design a hunter that would be successful in every possible environment, which would have been impossible due to the sheer amount of ecological variants, they designed a hunter that injects its embryo in their prey, copies the DNA, and in doing so, copies all their adaptations to the environment, so they created a beast with the ability to quickly evolve to the top of the food chain of any planet by stealing the evolutionary work that the native species have been accumulating during thousands of generations. Truly a brilliant and monstrous design.

    Why 'Godzilla' Reserves His "Special Attack"

    From Redditor u/PHD_Cassowary:

    One of the main complaints I tend to see about the 2014 Godzilla movie is the fact that Godzilla didn't use his atomic breath at the beginning of his fight with the M.U.T.O.s. But the reason for this is actually pretty simple. In past installments, it has been established that this attack is, of course, radioactive. We can infer from this that the Legendary Godzilla's atomic breath also uses radiation as fuel. We know from Serizawa's exposition on Godzilla that he is from a time where monsters used radiation as a food source.

    From there, the connection is easy. The reason Godzilla reserves his atomic breath weapon is because it's his source of energy - using it is the equivalent of vomiting on an enemy, albeit much more powerful. This also explains the lightshow on his spines; while it could be explained as him "charging" his breath, it's far more likely that this is a threat display. It's a last ditch effort to drive away his enemy, rather than waste energy with the atomic breath.

    Kong In 'Godzilla vs. Kong' Is An Adolescent

    From Redditor u/DungeonsAndMagicShow:

    If you pay attention during the Hollow Earth scenes, you'll notice that everything is oversized for him. The doors, the chair, even the statue (or petrified ancestor?) is hilariously huge by comparison.

    Additionally, in the artwork you see in the film, you'll notice previous Kongs are roughly the same height as Godzilla. In this film, there's a sixty-foot difference.

    This is also why he isn't King... he's just a Kong.

    'Godzilla' Actually Cares About Civilians

    From Redditor u/TheTjTerror:

    In Godzilla (2014), Godzilla actually cares about civilians.

    Watching this movie again, I noticed a few things. He never goes out of his way to hurt civilians. Actually waiting before getting involved. In the bridge scene, he waits for the bus to pass before pushing through/destroying the bridge, despite the tank shells causing him pain or annoying him. In Hawaii, he seems to be trying to subtly lure the evil creature out to sea instead of towards the city.

    In the city, as the wife watches when the bunker door closes, Godzilla seems to keep the creature in place instead of attempting to throw it in any given direction, possibly crumbling buildings. (side note: Would a creature as old as Godzilla even be able to understand what buildings are?)

    In the finale, Godzilla being clearly weakened during the fight, avoids any confrontation between him and the soldiers, even though they previously showed intent to harm...

    Those Darn Scarabs In 'The Mummy'

    From Redditor u/tapsoda:

    The reason there are so many scarabs in Hamunaptra...

    Is because they ate and multiplied from all the dead soldiers at the beginning of the movie. Notice how all the [cadavers] were missing when they returned to Hamunaptra.

    King Ghidorah Wiped Out Godzilla's Entire Species

    From Redditor u/whiplash10:

    Judging by Skull Island's post-credit scene and King of the Monsters, Godzilla and King Ghidorah have some bloody history. The question is: why are they fighting? My guess is that King Ghidorah was responsible in destroying Godzilla's entire species. Dr. Serizawa's claims that Godzilla was the Alpha Predator is very much true. They were the apex species rivaling Mothra's and Kong's. However that all changed when King Ghidorah arrived.

    King Ghidorah was such a threat that the entire Godzilla species attacked the monster. It did work, but at the cost of the destruction of almost the entire Godzilla species. Because of this event, the balance has been disrupted. The M.U.T.O.s and Skullcrawlers, for example, were free to expand and grow, causing the M.U.T.O.s to harvest the Godzilla corpse to become more powerful and the Skullcrawlers decimating Kong's race. Before Godzilla went into slumber, his powers were severely weakened due to King Ghidorah, and Godzilla could not regain his lost abilities.
