Top 10 Dumbest Alien Weaknesses In Movies And TV

They may hail from out of this world, but they still have to follow some sort of logic. Welcome to WatchMojo.com, and today we’re counting down our picks for the Top 10 Dumbest Alien Weaknesses in Movies and TV. For this list, we’re scouring all of science fiction to locate the most ridiculous things that aliens have been vulnerable to in film and television. You thought Kryptonite was bad? You ain’t seen nothin’ yet.

This Canadian sci-fi series established the power of the Gua from the beginning. These aliens came to Earth, captured humans for their experiments, and made plans to take over the world. Therefore, it’s surprising to learn that one of their weaknesses is the commonly found mineral we know as salt. The Gua can become addicted to salt much like humans can become addicted to drugs. Watching the Gua be harmed by a simple mineral makes it hard to feel threatened by them. At least now we know that if they ever invade Earth in real life, all we need to do is to carry around a saltshaker. Huh; what do you think pepper would do?

#9: High-Pitched Sound / Slingshot “2001: A Space Travesty” (2000)

Top 10 Movies to Watch While High

This sci-fi spoof isn’t exactly a shining star on Leslie Nielsen’s résumé, but one specific alien death takes the campiness to the next level. It’s a story jam-packed with aliens, terrorists, clone sand – for some reason – the Three Tenors. In an onstage kerfuffle between Marshall Dick Dix and some of the baddies, Dix ends up hitting Pavarotti where the sun don’t shine, and the resulting high note is enough to hurt anyone’s ears. However, it does more than that to the alien holding the giant weapon: she’s transformed from her human form back to her extra-terrestrial appearance, and sent floating around the theater. That leaves the alien vulnerable to the slingshot attack that ultimately sends it packing. Right.

#8: Crotch Shots “The Watch” (2012)

Top 10 Movie Crotch Shots

This critically panned comedy finds a suburban neighborhood watch trying to stop an alien invasion. Obviously. In their quest, the crew ultimately discovers that the aliens’ brains are located inthe most unlikely of places: their crotches. Naturally, this gives them permission to hit below-the-belt. Watching the group tear aliens’ genitals off is cringe-inducing, to say the least, and funny ina 9-year-old boy kinda way – we guess. But for that to be the vulnerability that ultimately fells an extra-terrestrial race is silly. We’ve heard of thinking with your you-know-what, but this is just ridiculous.

One of the less successful teen horror flicks of the ‘90s – despite its star-studded cast – “The Faculty” throws some sci-fi into the mix in an attempt to truly terrify its audience. Aliens are in control of an Ohio high school, and it’s up to a diverse group of students to stop them. Leave it to the stoner character to figure out that the aliens need water to survive, and that if they inject them with his homemade, ecstasy-like drug they’ll dry up and die. The best part? The teens decide that to decipher which of them is an alien, they have to take the drug themselves. Hey movie studios: whatever happened to the “DON’T do drugs” message?

#6: Hits to the Z-Logo “Mighty Morphin Power Rangers” (1993-95)

Top 20 Mob Hits In Movies

In season two of “Power Rangers,” the Putty Patrollers are seen as strong, threatening, and nearly invincible. You’d think that these aliens would have a weakness that is really difficult to get at, right? Think again. The Rangers find that all it takes is a hit to the Z-emblem on their chest armor for these clay warriors to explode into pieces. As a result, the Putty Patrollers are actually very easy to defeat. That’s kind of a major design flaw, dontcha think?! Especially considering these are supposed to be Lord Zedd’s upgraded version of Rita Repulsa’s foot soldiers… A weakness this, well, weak certainly doesn’t make for the most entertaining television…

#5: Head & Shoulders “Evolution” (2001)

Top 10 In Their Head Characters in Film

Think of a few things you could use to kill an alien. Did shampoo even come close to popping into your head? No? Well, maybe you should think outside the box. The humans in this sci-fi comedy certainly do when they realize that Head & Shoulders uses selenium disulfide as an ingredient, and that could be poisonous to the nitrogen-based aliens. There’s a fancy movie justification involving the periodic table, and the poisonous relationship between arsenic and carbon-based life forms on Earth, bla-bla-bla. But we think the simplest explanation for this weakness is two words: product placement.

#4: Computer Virus “Independence Day” (1996)

In “Independence Day,” aliens plan a massive attack on Earth by strategically placing flying saucers in major cities and even enacting a force field around their entire mother ship. So, what could possibly bring down such an obviously technologically advanced race? A friggin’ computer virus! With a plan to use a Mac laptop to infect the mother ship, computer expert David Levinson and volunteer pilot Captain Hiller head to their target, during which time the aliens’ force field is destroyed and the humans attack the ship with missiles. Easy-as-pie! Of course, now that we’ve fended off the aliens, Apple rules the world… Maybe for the sequel, the aliens will finally get Norton AntiVirus.

After aliens come to Earth and capture three warships in a force field, the people on the USS John Paul Jones must find a way to defeat them – man, aliens and their force fields! Eventually, the humans discover that the aliens’ simple but crucial weakness is something as readily available as sunlight. As you can imagine, this makes them extremely vulnerable to attacks while they’re on Earth. For example, in one scene, the crew shoots out the alien ship’s windows, which blinds the aliens and disorients them. Talk about an easy shot. Hey, the movie’s based on a board game; did you really expect something highly complex?

Bombs can cause serious damage to a large area, yes. Now, we’re not bomb technicians or engineers or scientists or anything, but we figure saying that a nuclear bomb can destroy an entire planet is pretty preposterous. Leave it to this classic “bad” movie for a single nuclear explosion – caused by an atomic bomb in this particular example – to make the planet go bye-bye. The explanation is some highly scientific – albeit outdated – one about the atmosphere of the Psychlo planet reacting with the radiation and thus exploding to smithereens. Logical? Not according to today’s science. You’d expect more from a story written by a SCIENtologist… Before we reveal our top pick, here are some honorable, or in this case, dishonorable, mentions: - Pleasant or Cute Things, Kindness, etc. “The Fairly OddParents” (2001-) - “Indian Love Call” by Slim Whitman “Mars Attacks!” (1996) - Destruction of the Central Command Center “Battle: Los Angeles” (2011) - Earth Bacteria / Microbes “War of the Worlds” (2005)

#1: Water “Signs” (2002)

3 Reasons To See The Shape Of Water - Review! Mojo @ The Movies

Before M. Night Shyamalan’s career went down the toilet, he made a few thrilling films that were well received by audiences. “Signs,” for the most part, was a suspenseful movie about discovering an alien invasion. However, at the end of the movie, the aliens were infamously defeated by water - of all things! Did the aliens not notice when they were plotting a course for our planet that most of the Earth is covered in the stuff? That’s almost as absurd as having trouble with pantry doors. This seemingly gaping plot hole notwithstanding, audiences and critics seemed to like the story. Do you agree with our list? What do you think is the dumbest alien weakness?
