Voting Rules
Vote up the creatures you think are the most powerful.

Star Wars has long been home to some of science fiction's most interesting and devastating creatures, monsters, and beastly beasties. Since the franchise's earliest days, Star Wars fans have enjoyed giant trash monsters, abominable snowmen, and terrors lurking just beneath the sand. Many new dangerous creatures have since been added to the franchise, thanks to series' on Disney+, which houses similarly big baddies in the MCU.

While it's well known that there are some terribly powerful creatures in the Star Wars franchise, it's challenging to determine which is the most powerful. After all, it depends on the situation, so a Rancor may seem terrifying on the ground, but blasting them from the cockpit of an X-Wing is something altogether different. Regardless, the choice is yours, so take a look at some of Star Wars' biggest creatures and be sure to upvote the ones you think are most powerful to see which one rises to the top!

    Zillo Beasts

    Zillo Beasts were long thought to be extinct, but one was awoken on its native planet of Malastare. That belief was proven untrue when the Clone Wars came to the planet, and an electro-proton bomb unearthed what was believed to be the sole surviving member of its species. Zillo Beasts are massive, measuring 318 feet (97 meters) in both length and height. They have a third arm extending from their back, massive spikes along their tails, and huge jaws capable of eating whatever gets in their way. They also weigh in at around 60,000 metric tons, so "massive" is truly the best word to describe them!

    Another interesting characteristic of the Zillo Beast is its hide, which is impervious to any and all damage. Blaster fire won't dent it, and a lightsaber won't cut through it. Ultimately, the Galactic Republic had to slay the Zillo Beast on Malastare using a special toxin because blasting it had no effect. Though the beast was dead, Palpatine ordered for it to be cloned. At the time, he appeared to want to use its hide to benefit the Grand Army of the Republic, but in reality, he wanted it for his own nefarious purposes.

    During the Imperial Era, another Zillo Beast was known to exist on the Benathy home world. It was worshipped as a god and played a central role in their culture. When the Empire battled the Benathy, Darth Vader was able to defeat it but not kill it. Years later, Vader's grandson, Kylo Ren, managed to successfully slay what was likely the last Zillo Beast in existence. After doing so, he ordered the Benathy to swear allegiance to the First Order.

    Summa-Verminoth

    The summa-verminoth may be the largest creature in the entire Star Wars universe. They measure as long as 24,383 feet (7,432 meters) and live in space. They could be found in the Akkadese Maelstrom around the planet Kessel. A summa-verminoth has numerous eyes and electrified tentacles, each covered with suckers and electrified stingers. They use their tentacles to grab prey, which can be anything that gets close to them, though they do enjoy eating starships.

    Summa-verminoth look a bit like giant space jellyfish, and there's a good reason for that. They weren't originally in the script for Solo: A Star Wars Story and only exist thanks to a wild pitch. James Clyne is quoted in The Art of Solo: A Star Wars Story with the following explanation of how he got the giant creatures into the movie:

    The jellyfish in the Kessel Run, again, came from throwing dumb ideas out in a meeting. I literally opened my sketchbook and pitched, "What if the Falcon had to fly through a jellyfish?" [laughs] "Yeah. All right. OK." But we come back and, "There's a jellyfish in the presentation."

    Director Ron Howard gave the idea the thumbs-up, and before long, the crew was calling this gigantic beast that eats starships "Space-o-pus," which is certainly fitting!

    Krayt Dragons

    When you think of a krayt dragon, there's a good chance you might imagine a different beast than another fan. That's because "krayt dragon" is an umbrella term for any giant reptilian beast native to Tatooine. Several different species fall under this name, including the canyon krayt and the greater krayt. Canyon krayts are smaller than many of the other species. That said, canyon krayts are large, formidable beasts with brown skin and yellow eyes. They can be found in rocky caves and canyons, where they hunt whichever unfortunate creature stumbles upon it.

    Larger beasts known as greater krayt dragons are massive, monstrous creatures that move so quickly beneath the sands of Tatooine that they effectively swim through it. They accomplish this with their 10 strong legs and long, whip-like tails. Greater krayts spew acidic saliva capable of dissolving almost anything it touches. They are feared across Tatooine, and for good reason. They're incredibly dangerous and often require dozens of people carrying some heavy ordinance to bring them down.

    Jawas are particularly fearful of the greater krayt dragon, as they have no defense against them. Tuskens are equally fearful of them, though they do hunt canyon krayts for their pearls. This is an important rite of passage for a young Tusken. When a young Tusken boy reaches the age of 15, he must slay a canyon krayt and remove the pearl found inside its stomach. Once this is complete, the boy becomes an adult in the clan.

    Geonosian Brain Worms

    The Geonosians were the sentient species native to Geonosis and played a significant role in the galactic civil war. Geonosis was the location of the first major battle in the Clone Wars, and the planet continued to provide the Separatists with droids for its armies throughout the conflict. Geonosians also helped design the Death Star, so they significantly impacted the events of the films and television series.

    The Empire eradicated Geonosis when its usefulness came to an end, leaving only one individual alive in the galaxy. The species itself is not monstrous, but an aspect of its lifecycle certainly places it on that side of the line. A queen was capable of breeding brain worms, a parasite that entered a host body and took complete control of it. This included the dead, so brain worms could be used to reanimate the dead, making them particularly nasty. Once infected, one person can infect others, making brain worms particularly dangerous creatures.

    Rancors

    The rancor is probably one of the most recognizable beasts from the Star Wars universe, and that's entirely due to its depiction in Return of the Jedi. In the movie, Luke Skywalker finds himself without a lightsaber, trapped in a rancor's lair. Using the Force (and a big rock), he manages to call down the gate, pinning and slaying the beast. That was the first rancor seen on film, but it was hardly the last. Because of their popularity, rancors have appeared all over the expanded universe, and as it happens, there are tons of different kinds of rancors.

    Rancors are semi-sentient creatures native to the planet Dathomir. On their home world, they formed a semi-symbiotic relationship with the Nightsisters, but that was a long time in the ancient past. More recently, rancors have been exported all across the galaxy, where they're prized possessions in various menageries like Jabba the Hutt's. They're often seen as mindless monsters because of their size and fierce appearance, but they're much more than that. Many rancors are passive creatures who only tear people apart because they're thrown into pits with them.

    Because they've been exported to different planets across the galaxy, different types of rancors have emerged over time. While they're all large, some are smaller and more agile. They come in a variety of colors, and some are more violent than others. They're formidable creatures, and their armored hide is strong enough to withstand blaster fire. In canon, there have been several subspecies introduced, including jungle, shadow, and rage rancors.

    When they're young, rancors are given blinders so they cannot look upon a person. This is done because they imprint on the first person they see. This creates a strong bond between the rancor and their "person," such that they might one day be able to ride them into battle.

    Rathtars

    Love it or hate it, the sequel trilogy introduced a whole bunch of extraordinary creatures to the Star Wars galaxy. The most interesting has to be the rathtars, which Han and Chewie were transporting aboard the Eravana. Moving these monsters was a high-paying gig, entirely due to how insanely dangerous they are. Once they were let loose, they tore through the ship, destroying everything and eating anyone who got in their way.

    Their voracious appetite makes sense when you learn that they share a common ancestor with Sarlaccs. Both creatures evolve into giant beasts with massive mouths that dominate their heads. Rathtars are known throughout the galaxy as some of the most dangerous creatures around. They grow to about 1,433 pounds (650 kilograms), and with their tentacles, they measure about 20 feet (6 meters) in length, so they're not the biggest beasts in the galaxy. That said, they are some of the nastiest!

    Rathtars reproduce via fission, so if you have one, there's a good chance it will split into two, and so on until things get really bad. This makes them particularly dangerous if population control measures aren't taken, so there's nothing about a rathtar that isn't incredibly scary. Instead of "handling with care," it's probably best to blast away and get out of their reach (which is quite far, thanks to their tentacles).
