- This article covers the Showa incarnation of Moguera. For the Heisei incarnation of the character, see MOGUERA.
One of the weapons of the Mysterian invaders, Moguera was unleashed in Japan, where it destroyed a village by triggering severe earthquakes while underground. Moguera soon surfaced and began rampaging through the countryside before the JSDF blew up a bridge as the machine was crossing it, destroying Moguera. The Mysterians would deploy a second Moguera to defend their dome when the Earth Defense Force began attacking it with Markalite Cannons. The second Moguera accidentally burrowed too close to a Markalite Cannon, which toppled onto it and destroyed it. The Showa Moguera was the inspiration behind the G-Force mecha MOGUERA from Godzilla vs. SpaceGodzilla, and has been featured in some non-film media since its debut, such as video games and the television show Godzilla Island.
Moguera's Japanese name, Mogera (モゲラ), is derived from mogura (モグラ), the Japanese word for "mole," due to the fact that Moguera possesses the ability to dig, similar to a mole. Additionally, before Toho decided to make the Moguera a mecha, it was drawn as a giant quadrupedal animal similar in appearance to a mole in early concept art for The Mysterians. In Godzilla Island, it is instead called Proto-Moguera (プロトモゲラ in order to differentiate from Puroto Mogera)G-Guard's Moguera.
Moguera's name has been spelled several different ways in English. While the character's trademarked English name is "Moguera," concept art for The Mysterians offered the English spelling Mogera, which has been used in other media and merchandise since then. Additionally, both Bandai's 1984 Godzilland merchandise line and the 1988 NES video game Godzilla: Monster of Monsters! utilized the English spelling Mogela.
During initial story development for The Mysterians, Moguera was originally envisioned as a fully living biological creature, with related early concept designs and storyboards showing off a quadrupedal reptilian mole-like monster. Ultimately, however, the production staff changed Moguera to a robot in order to differentiate it from previous Toho film monsters. The robot Moguera design retained several elements of the original organic design, such as the drill-tipped mole-like nose, the saw-shaped ridge on its back, and the shape of its tail.
A 30 centimeter prototype model of Moguera was constructed as a reference for the proportions of the suit to ensure it would be able to fit a human actor. This concept model differed in a few ways from the final design of the suit, possessing larger eyes, a more pronounced metal jaw, a larger drill nose, a thinner, more humanoid body shape, and more human-like hands with a single large triangular finger and thumb. This model was used in promotional materials for the film, and merchandise from Marusan and Bullmark in the 1980's used it as a reference instead of the suit.
The head of the Moguera suit was modeled by Teizo Toshimitsu, with the Yagi brothers Kanju and Yasuei handling its body. The suit's head, upper body, and lower body were all composed of separate pieces that had to be put on individually. The suit's metal surface was painted over with a vinyl material. Both suit actors Haruo Nakajima and Katsumi Tezuka wore the Moguera suit. Because the suit's upper and lower bodies were separated, the actor was filmed only wearing the bottom half of the suit for scenes of Moguera's legs stomping and kicking buildings and jeeps. After The Mysterians was completed, the suit was kept in storage in one of Toho's soundstages. It was destroyed in a fire resulting from a pyrotechnic accident on the set of 1974's Prophecies of Nostradamus.
A miniature puppet one-half the size of the suit with a rotating drill nose and rotating arms was created to depict Moguera No. 2 burrowing underground. Initially, the filmmakers had planned to construct a self-propelled puppet of Moguera's upper torso with a caterpillar track for this scene, but found it too difficult to realize. However, photographs exist of this self-propelled miniature under construction, with built-in gears visible inside it.
Moguera is a giant bipedal robot with a bulky segmented body. Moguera's chest and upper legs are steel gray in color and possess numerous horizontal indentations that give them a striped appearance. Moguera's upper arms and the lower part of its legs are a light bluish-green color, while its head, neck piece, hands, and feet are gold. Moguera has a large drill for a nose, and its eyes sit atop its head while flaring out to the sides of the nasal drill. Moguera has two antennae sticking out of the top of its head that move back and forth. Moguera tucks these antennae behind its head while burrowing. Moguera has a barely visible mouth under its nose with a transparent lower jaw. Moguera's hands are cone-shaped with a gap in their center, giving the vague appearance of them possessing two fingers. Its feet are rectangular, and consist of two pieces. Moguera has a large circular saw blade protruding from its back, and a fat gray tail.
In The Mysterians, Moguera is a war machine constructed by the Mysterians to aid in their invasion of Earth. The Mysterians constructed at least two Mogueras, as after the first one was destroyed a second one was deployed to defend the Mysterian Dome from the Earth Defense Force.
In Godzilla Island, Moguera is called Proto-Moguera and is a prototype of G-Guard's Moguera. Proto-Moguera is stolen by the Xilien agent Zagres and used as one of the invaders' pawns in their scheme to destroy Godzilla Island.
Before the Mysterians revealed themselves to humanity, they sent Moguera to attack a village and destroy its shrine. Moguera moved up the river and was attacked by policemen. Moguera then destroyed a power plant, and attacked a town. The JSDF provided cover for the evacuating residents with rifles, mortars, machine guns, flamethrowers, and 24 Twin Rocket Cars, but their weapons had no effect. However, they were able to lure Moguera to the edge of a bridge rigged with explosives. Upon detonation, Moguera toppled into the river below and exploded.
Moguera (No. 2)
After the first Moguera was destroyed, another Moguera named Moguera No. 2 (モゲラ(2号) was released and it attacked from underground. It dug up too close to a Mogera (2-gō))Markalite Cannon, which collapsed on it, destroying the machine.
Moguera appears as a background character in the addition and subtraction Get Going! Godzilland OVAs. Moguera is frequently seen burrowing or popping out of the ground, but never has any dialogue or interaction with the other kaiju. In the opening sequence, Moguera can be seen with its upper body poking out of the ground while holding an umbrella with a small ornament of a Mysterian hanging from it.
Moguera appeared in the TV show Godzilla Island, and was known as Proto-Moguera (プロトモゲラ so that it would not be mistaken for the Puroto Mogera)other MOGUERA that appeared in Godzilla vs. SpaceGodzilla. Proto-Moguera was ultimately stolen by Zagres after Black Mechagodzilla was captured by G-Guard. Proto-Moguera was then sent retreating into space with Zagres after Torema piloted the superior Mechagodzilla against it.
Moguera's body is constructed with space steel, an extraterrestrial counterpart to steel which is over 200 times as strong.
Moguera has the ability to burrow underground.
Moguera can fire lasers from its eyes. They are relatively weak, but pack enough explosive force to disable a 24 Twin Rocket Car. Its eyes glow blue a few seconds before firing. Moguera also emits a high temperature.
While Moguera is impervious to the JSDF's conventional weaponry, it can be easily destroyed with enough force. The first Moguera deployed by the Mysterians was destroyed when the bridge it was crossing was detonated and it fell into the river below. The second Moguera met its end when it burrowed too close to a Markalite Cannon, which toppled onto it.

Appearing on the first world with Gezora, the giant mecha Moguera will follow Godzilla and Mothra throughout the game, attacking them on each world. Moguera lacks versatility as he is only able to walk across the stage rather slowly, usually in response to the player's movement; in fact, if the player advances on Moguera there is a chance he will back himself into the corner. On top of that, a strange glitch triggers that makes Moguera unable to attack or fight back at all until the player moves backwards. Moguera can jump, not very well however, but it will still be enough to knock Mothra to the ground if she is too close. While Moguera lacks the maneuverability of Gezora, he makes up for it with fire power as his Eye Beam will deal noticeable damage to either Godzilla or Mothra; furthermore, the beam is incredibly accurate and its very rare that either Godzilla or Mothra will be able to dodge it. Moguera has two variations on his Eye Beam, one a bright red and the other a brown; which he uses depends on who he is fighting against, bright red against Godzilla and brown against Mothra. The difference in the beams, however, is purely cosmetic.

Like the Heisei Moguera, the original Moguera did not have an actual roar, although its weapons, engine and attacks did make sounds. As it walks, Moguera emits a continuous beeping sound.
- Moguera was the first mecha to appear in a Toho film.
- In Godzilla: Final Wars, a Canadian child portrayed by Jordan Fleming is seen playing with several Godzilla toys, and a figure of the Showa Moguera is among them.
- Episode 48 of the anime Sonic X features Sonic and the gang venturing into a volcano, only to be attacked by a robotic monster named "Mongroun" that looks almost identical to the Showa Moguera. The episode also features numerous other references to Toho kaiju films.
- The monster Megarion from The Justirisers and Super Fleet Sazer-X serves as a visual homage to Moguera, with a mole-like mechanical appearance and drill-like appendages.
- While Space Steel is a fictional metal, making strong alloys in space has basis in real life science, by manufacturing metals or other material in microgravity. The lack of gravity allows alloys or other substances to better mix more effectively than in an environment with gravity with fewer defects and better control in removal of impurities or sedimentation, resulting in a better product.
