Films: Monsters (2010), Monsters: Dark Continent (2014)
Location: Civilized Area/Desert
Height/Weight: Ranges from that of average horses to that of mountains.
Summary: Sometimes, we dread to think of what might happen if aliens attempt to communicate with us or even try to live with us. On one hand, we could be best friends. But on the other, we could just royally screw it all up. And it'd be twice as annoying if we were the ones who started the whole "invasion" in the first place.
History: One day, a NASA probe said to contain alien life forms crashed into Central America, yet the creatures still lived. They grew and multiplied, and soon became a major concern for America. A great wall was being constructed on the border to keep them out, yet both man and beast cannot tolerate this quarantine. It won't be long before the Infected Zone becomes irrelevant.
Notable Kills: None.
Final Fate: In the end, it is unclear whether the aliens we see were killed, but we know that they do not mean us any harm. However, in the time after the incident, the monsters began to spread across the world and even into the Middle East, where they became positively gigantic. And yet, almost all casualties are of human action, never monster. Humanity is just really damn stupid sometimes. Either way, the fate of both species remains uncertain...
Powers/Abilities: These aliens can evolve over relatively short time periods and into all sorts of diverse forms.
Weakness: Heavy artilery.
Scariness Factor: 3.5-The sheer size and oddity of these beings and their many different looks can be unnerving, dangerous even. Provoking an alien is the same as poking a bull elephant, except it's at least five times the size. But then you realize that these things are mostly docile, only attacking that which attacks them. If they weren't taking up so much space, perhaps they'd be more welcome. But for now, we've made monsters out of ourselves...well, some of us, anyway.
Trivia: -The first film was the directorial debut of Gareth Edwards, who did all of the effects by himself with the miniscule budget, and would still go on to direct the 2014 incarnation of "Godzilla". Definitely a glow-up.
-Edwards is...rather insistent that that there are no immigration metaphors in his movie. This is despite taking place near the border, the storyline being about getting over said border, and on top of all of that, how it demonstrates just how inept Americans are at accepting foreigners most of the time.
