Megalon (メガロ,   Megaro?) is a giant insectoid kaiju created by Toho that first appeared in the 1973 Godzilla film, Godzilla vs. Megalon.


Megalon's name likely comes from the combining form "megalo," which means 'abnormally large' or 'great.'


Megalon superficially resembles a cross between a cockroach and a rhinoceros beetle, though standing upright. Despite being an underground creature, Megalon is noticeably colorful, combining silver and grey tusks and claws with an orange-and-black carapace and wings. Megalon's forelimbs terminate with two sharp, drill-like appendages, which are never seen to be individually prehensile, at least in Godzilla vs. Megalon, always moving in tune with the monster's arms.


Megalon is sometimes considered one of the least intelligent Toho kaiju. This is demonstrated by the fact that he is easily manipulated by external stimuli. For example, Megalon followed Jet Jaguar simply because he was curious, and he is also very temperamental, as seen when he goes into shock when he loses sight of Jet Jaguar and begins to jump and thrash about. His battle tactics also seem to be lacking in terms of strategy, as he never once utilizes his lightning horn beam against Godzilla nor Jet Jaguar. Additionally, he seems to enjoy charging at both his enemies headfirst, although all said enemies had to do was simply step out of the way to avoid him. Without Gigan by his side, Megalon would probably not have lasted as long as he did during the film's climactic last battle.


Megalon is a gigantic insectoid being that lives deep underground in the subterranean kingdom of Seatopia. Megalon is seen as the Seatopians' god, and is called upon by them to defend their home from threats.

Jet Jaguar vs Megalon

Megalon battles Jet Jaguar in Godzilla vs. Megalon

Megalon is the god to the Seatopians, and he was their way to take revenge on the humans who were damaging their world with nuclear tests. They called upon Megalon to destroy the humans and sent the captured Jet Jaguar to guide the monster on his rampage through Japan. The people of Japan revolted and attacked the beast, to no avail. Help arrived when Goro Ibuki, the scientist who created Jet Jaguar, managed to free the robot from the control of the Seatopians. He sent Jet Jaguar to Monster Island to find Godzilla. In the time that Jet Jaguar was gone, Megalon was lost and confused. Jet Jaguar returned to Japan and reprogrammed himself to grow to kaiju size then attacked Megalon, causing the Seatopians to contact the M Space Hunter Nebula Aliens and ask for Gigan's assistance. Gigan arrived and he and Megalon double-teamed Jet Jaguar. Eventually, Godzilla arrived and joined forces with Jet Jaguar against Gigan and Megalon. After a long battle, Gigan retreated back to outer space, leaving Megalon at the mercy of Godzilla and Jet Jaguar. The two monsters pummeled the helpless Megalon before he finally burrowed back to Seatopia, defeated.

Godzilla Island

Cast megalon

Megalon in Godzilla Island


Megalon possesses a sizable array of abilities. He is capable of firing a lightning beam from the horn on his head, and can spit napalm bombs from his mouth. Megalon's most notable feature is his drill hands. These drills are useful in hand-to-hand combat, and can combine together into a single rotating drill which allows Megalon to burrow underground at the speed of mach 2. Megalon can jump high into the air, and travel for up to ten kilometers at a time using this method. Megalon can use his wings to fly at a speed of mach 3, and can travel underwater at a speed of mach 4.

In video games such as Godzilla: Save the Earth and Godzilla: Unleashed, Megalon's abilities vary from his film appearance. He can no longer fly for extended periods of time, only use his wings to briefly hover in the air. Each of his drill hands is now prehensile, making his punches capable of drilling into an opponent's flesh. He can also discharge electrical energy through his punches. In these games, Megalon's special ability consists of him generating a magnetic field that draws opponents towards him, before unleashing a powerful electromagnetic pulse that damages enemies and sends them flying.

Video Game Appearances

Even though Megalon only appeared in one film, he remains a popular character, and has appeared in several computer and video games based upon the Godzilla franchise, including Godzilla: Destroy All Monsters Melee, Godzilla: Domination, Godzilla: Save the Earth, and Godzilla: Unleashed.

Godzilla: Domination!

In Domination!, Megalon has the power to do a leech probe, in which Megalon grabs on to his opponent and bites them four times, each time hurting the opponent and healing Megalon. This move can only be done if Megalon is next to a enemy. He also has the ability to unleash three blasts of energy from his horn, which will quickly fly around him before slamming into the ground. In the same game, Megalon's napalm bombs are altered to resemble real bombs or naval mines.

Godzilla: Save the Earth

Megalon has the ability to execute an energy punch and create a damaging arc of energy. As a Rage Attack, Megalon can create a Magnetic Vortex, in which Megalon shuffles his wings and all the monsters get drawn close to him. When one is close he releases a mini-pulse of energy, dealing immense damage.

Godzilla: Unleashed


Megalon in Godzilla: Unleashed

Height: 88 meters
Weight: 64,000 tons

"Megalon is a guardian monster of the Seatopians, who live beneath the earth's oceans. Having no special love for human beings, he has once again aligned himself with the alien invaders in hope of eliminating the human population once and for all. Megalon is a very well-rounded combatant, with decent melee, grappling, and ranged capabilities. He has a special affinity for electricity, allowing him to employ lightning and EMP attacks without danger to himself. Megalon's hands are high-speed drills, which allow him to burrow underground or simply gore his opponents in hand-to-hand combat."

As a part of the Aliens faction, Megalon has aligned himself with the Vortaak in their quest to take over the Earth. He retains the same abilities he possessed in the previous Atari games, Godzilla: Destroy All Monsters Melee and Godzilla: Save the Earth.

Kaiju Guide

Megalon, the Insect Monster

Megalon 0

A descendant of a civilization from the Lemurian continent, which sank to the bottom of the ocean 3 million years ago. Adversely affected by weapons-testing carried out on the Aleutian Islands, the undersea kingdom retaliated by launching a land invasion. Megalon can move at high speeds underground by using its arms, both partitioned drills, in tandem. Its attacks include the spitting of napalm bombs from its mouth and the shooting of anti-beast lasers from the tip of its horns.

Megalon was born as a rival to the TV special-effects giant monster heroes during its day, and was designed as an amalgam of the beetle, the cicada, and other insects that were popular with children at the time. When moving, it makes great leaps like a grasshopper.

Cinema Shares' Godzilla vs. Megalon Adaptation

Megalon in the promo comic

Megalon in Cinema Shares' Godzilla vs. Megalon comic adaptation

In the American promotional comic produced by Cinema Shares for Godzilla vs. Megalon, Megalon is depicted as not being Seatopian in origin, but rather appearing from beneath the Earth during an undersea eruption, and coming to attack cities to satisfy his "Energy Hunger." He is killed brutally by Godzilla after having the back of his spine bitten into.

Godzilla, King of the Monsters

Megalon returns from underground in this manga, although it is never stated whether he was under the control of the Seatopians or not. He emerges from underground while Godzilla is fighting Biollante Neo and attacks using his drills, ripping into Godzilla's chest. He accidentally kills Biollante Neo with his lightning beam after Godzilla throws her at him, and is defeated when Godzilla swipes the top of his horn off, and burns him to death with his Atomic Breath.

Godzilla: The Half-Century War

Godzilla: Rulers of Earth

Megalon first appeared in Godzilla: Rulers of Earth issue #9 where he fought the monster King Caesar in a flash back explaining the monsters' origins. Megalon would fall into the Earth's crust with King Caesar when an alien ship crash-landed into the ocean near them as they fought. Megalon's image would be later seen in the mural on Infant Island, next to the other "fire monsters."

According to Matt Frank, Megalon was supposed to appear throughout the series, originally being Godzilla's opponent in Las Vegas, but was left out of the story due to time constraints.

Godzilla: Rage Across Time

Megalon appeared in issue #1 of Godzilla: Rage Across Time, where he, alongside Gigan, were controlled by Zhenjin Khan, the dragon master, as he lead them and his Nebulan/Mongolian troops, as sent and ordered by the Chinese emperor Kublai Khan, to obliterate Japan in 13th century Japan. The soldiers of Japan fought back against the Mongolians while the two monsters laid waste to the land. Just when it looked like all hope is lost, the monsters were suddenly hit by an atomic beam that pushed back Megalon's napalm bomb. The user revealed himself to be Godzilla, who was drawn towards the duo's location to fight them. At first, Godzilla had the upper hand in battle by dodging the monsters' attacks and striking hard at them, but then Megalon and Gigan fought back and soon dominated over Godzilla with their well-coordinated teamwork. When it seemed like the leviathan was about to lose to these alien monsters, the Mongol relic that controlled them was destroyed by a fire arrow shot from Akio, the infamous woman warrior. Soon, with the monsters dazed and confused, the atomic leviathan shot an atomic breath at Gigan and swung his thick tail at Megalon. Afterwards, the two monsters decided to retreat and flew off into space while Godzilla destroyed the remainders of the invading army.

  • Megalon and Godzilla are seen in a magazine in Friday the 13th Part 3.


Like Baragon and Gorosaurus, Megalon's roar is an edited pitch of Varan's roar, whose roar was originally from Godzilla at the end of the original Godzilla film. In addition, Megalon also produces screeching sounds which are adapted from Ebirah's chirps and screeches. Megalon can also emit a deep laugh, created by altering his normal roar.
