10 Worst Godzilla Monsters That Almost Ruined the Franchise

Godzilla is arguably the most famous and powerful movie monster, spreading fear and destruction everywhere he appears. While many other giant monsters, known as kaiju, also feature in these films and have gained popularity, some characters from the Godzilla series are simply awful and disliked by fans – and with good reason.

As a lifelong Godzilla fan, I’ve seen a lot of monsters, and honestly, the worst ones are usually just…embarrassing. They’re often silly and weak, and really drag the whole franchise down. Sometimes, they’re not even developed enough to be interesting, which leads to pretty forgettable battles. Ultimately, these monsters weren’t just defeated by Godzilla – they kind of defeated the movies themselves, making for some seriously low points. They almost managed to ruin the fun, not just in the fights, but for the whole series.

Fairy Is the Smallest Mothra Kaiju

Mothra is a massive, queen-like monster, but she’s generally gentle, especially when compared to creatures like Godzilla. While her larval form is also huge, this isn’t true for all similar beings. Fairy Mothra, also known as Fairy, appears in the Rebirth of Mothra series.

Though named after a strong form Mothra takes in some 1990s Godzilla films, Fairy Mothra is actually quite small – only a little bigger than a regular moth. He mainly serves as a way for Mothra’s tiny priestesses to travel. While Fairy Mothra does have some powers, they aren’t very notable when compared to the other giant monsters in the series. He hasn’t been featured much since, likely because he’s not as impressive as most versions of Mothra.

Megaguirus Is Creepy Yet Generic

Megaguirus, inspired by the Meganulon insects from the film Rodan, is a much larger version of that bug species. She first appeared in Godzilla vs. Megaguirus and was one of the few entirely new monsters created during Godzilla’s Millennium series. While she had a frightening appearance and a dangerous stinger, many fans found the character ultimately disappointing.

Godzilla vs. Megaguirus wasn’t a bad movie, but it wasn’t particularly memorable either. Like the film before it, it benefited from being a step up from the American Godzilla movies. Ultimately, Megaguirus didn’t really leave a lasting impression, and the whole movie is easily forgotten. As the series went on, the filmmakers started focusing on reimagining classic monsters rather than creating brand new ones.

Moguera Has One of Toho’s Worst Designs

Moguera first appeared in the sci-fi film The Mysterians as a large, mole-like robot. It didn’t make a big impact compared to other monsters in films from that time. A redesigned version later appeared, but it mainly served as an opponent for the main monster, taking a lot of damage.

Moguera never stood out as a particularly exciting villain in the Toho films, and its version in the later Godzilla movies felt like a weaker take on the popular robotic enemy, Mechagodzilla. A big part of the problem is its design, which is based on the rather unremarkable mole. Without strong defenses or weapons, it’s simply an easy target for monsters to defeat.

SpaceGodzilla Is the Silliest Godzilla Derivative

The Heisei period of Godzilla films featured a lot of memorable monsters, and one of the last major villains was SpaceGodzilla. He was created when some of Godzilla’s DNA mixed with material from space, hence the name. Although his crystal-like body looked impressive, SpaceGodzilla himself wasn’t a particularly unique or intimidating monster – he came across as a bit silly and over-the-top.

SpaceGodzilla wasn’t as compelling a villain as characters like King Ghidorah or Mechagodzilla. It’s interesting to note that he was designed as the space-based threat, while Ghidorah, who is normally an alien, was given an origin on Earth in this series. Though some fans would like to see SpaceGodzilla return, a different, more engaging concept might be a better fit for that role.

King Caesar Was One of Toho’s Ugliest Kaiju

King Caesar debuted near the end of the film looking less like a fearsome monster and more like a worn-out lion costume. As the protector of a secret island, he battled Mechagodzilla but was quickly defeated. Luckily, Godzilla arrived to help, and this ended up being King Caesar’s only significant appearance in films for many years.

King Caesar’s appearance highlighted how low-budget the Godzilla films had become during the later Showa years, and his role in the story felt tacked on. It wasn’t surprising that Mechagodzilla easily defeated him, and a more fitting ally for Godzilla against the robotic monster would have been Mothra. King Caesar signaled a decline in the series, and unfortunately, he wasn’t a strong character to mark that ending with.

MUTOs Are the Biggest Waste in the MonsterVerse

The MUTO creatures were among the first monsters featured in the 2014 Godzilla film, serving as the main villains. Their design blends characteristics of insects, bats, and reptiles, and some have noted similarities to the monster from the Cloverfield movies. However, they didn’t make a very strong impact in the film and were actually a significant weakness.

The fight scenes in Godzilla (2014) were the weakest part of the film because the quick, constant cuts made it hard to follow the action. While Godzilla himself was still impressive, the MUTOs felt underdeveloped and like brief appearances. Later MonsterVerse installments haven’t improved their impact, making them a prime example of wasted potential for Legendary Pictures.

Megalon Is Another Unimpressive Bug Kaiju

Aside from Mothra, insect-based monsters often aren’t very popular and tend to be weak villains. This was definitely true in Godzilla vs. Megalon, where the main enemy was a giant, mutated cockroach. The concept itself isn’t great, and the final result is even less impressive – which, unfortunately, matches the overall quality of the movie he first appeared in.

Godzilla vs. Megalon is often considered one of the silliest Godzilla films. The battles and monsters are over-the-top and feel like cartoonish gags. The movie attempted to address environmental themes through the monster Megalon, but this message didn’t really come across, especially considering his bizarre origin in an underground civilization. Megalon hasn’t appeared often since, and while later versions of the character have been better, his debut didn’t make a strong impression.

Many Godzilla Fans Hate Minilla

Minilla, also called Minya, is a young member of Godzilla’s species and is considered his adopted son. Though he comes from a powerful lineage, Minilla looks quite different from Godzilla – he’s chubbier and has a more cartoonish, almost human-like face. He’s also noticeably weak and doesn’t have the ability to consistently breathe atomic breath. Instead, he puffs out smoke rings, which he surprisingly used to defeat King Ghidorah.

Many fans don’t care for Minilla, particularly because he embodies the more lighthearted and childish direction of the later Showa-era Godzilla films. He also comes across as weak, especially when considered as Godzilla’s son, even an adopted one. Although the American Godzilla cartoon’s Godzooky, who was presented as Godzilla’s nephew, shared some similarities, later versions of Godzilla’s offspring were much more powerful and intimidating.

Jet Jaguar Was the Worst Fit for the Godzilla Franchise

Jet Jaguar was a new character in Godzilla vs. Megalon, and originally, the movie was planned around him. However, Godzilla was added to draw a bigger audience. Jet Jaguar was a Japanese-made robot with the ability to grow to the size of a monster, and he helped Godzilla fight both Megalon and Gigan. By the end of the battle, Jet Jaguar and Godzilla seemed to become friends, even sharing a handshake.

Jet Jaguar felt like a product of the franchise’s increasingly playful direction, often appearing more as a teammate to other characters than a true hero. Created through a contest for children, his design is undeniably silly and lighthearted. While a size-changing, almost magical robot wasn’t entirely out of place given the series’ increasing absurdity, it was difficult to see him as a serious threat or savior alongside monsters that once represented unavoidable doom.

Zilla is Still the Worst Version of Godzilla

Many fans don’t consider the 1998 Hollywood Godzilla to be a true Godzilla. Its design, origins, behavior, and even what kind of creature it is were all significantly changed. Unlike traditional Godzilla, this version was much weaker and was actually defeated by the American military. It was essentially a giant iguana without iconic powers like atomic breath, and its unusual movement was another letdown for viewers.

The 1998 film featuring Zilla didn’t kickstart a successful American Godzilla series, and on its own, it was simply a forgettable monster movie. Zilla has made a few appearances since then, but usually ends up being defeated by the real Godzilla. Fortunately, Legendary Pictures and the MonsterVerse have delivered much better American Godzilla films, though Zilla will always be remembered as a disappointing attempt.
