In trailers
Gipsy Danger appears to be one of the main jaegers in the film; it is shown throughout the trailer more than any other Jaeger as well as its pilots. Gipsy Danger is seen battling a Leatherback in a mass of containers and tackling an Otachi with a ship. However, it is also shown in the trailer falling to its knees with its arm ripped off and the pilot climbing out of the head, although the second pilot isn't seen following...

Trivia
It is speculated that the second pilot of Gipsy Danger (the other being Raleigh Becket) dies after an unseen battle that severely damages Gipsy Danger's left side, costing it it's arm as well as a deep wound on its left breastplate. Of the two pilots piloting Gipsy, only Raleigh emerges from the wreckage. After this incident, Becket and Gipsy Danger retire for a unknown period of time, but are later called back to service when humanity begins losing the war against the Kaijus. The replacement pilot is an untested trainee called Mako Mori.

Moguera (モゲラ Mogera) is a Kaiju (Japanese giant monster) featured in two of Toho's science fiction films. The name is derived from mogura (土竜(もぐら) the Japanese word for mole.

Appearance
The Mysterians and Godzilla vs. Spacegodzilla

Showa
In The Mysterians, Moguera is a robot used by the Mysterians to assist in destroying humanity to make them bend to their will and supply them with a sufficient amount of land and women. It attacked a small village with its eye beams, and proved immune to machinegun fire, flamethrowers, and mortar rounds. It was destroyed when the bridge it was standing on collapsed due to the military dynamiting it.
A second Moguera appeared as Markalite beam cannons assaulted the Mysterians' base. This Moguera tried to destroy one of the Markalites by burrowing underneath it, but the weapon fell on top of it, crushing and destroying the short-lived second Moguera.

Heisei 
In Godzilla vs. SpaceGodzilla, M.O.G.U.E.R.A (Mobile Operation Godzilla Universal Expert Robot Aero-Type) was a UN-built mecha designed to fight Godzilla following the failure of G-Force's Mechagodzilla.
Mogera has an expansive arsenal of weapons. The most heavily-utilized and standard weapon are the plasma laser cannons built into its eyes, which rapidly fire yellow plasma shots. A drill bit is located in the center of its face, which can be used for close range fighting. It's cone-shaped hands are capable of releasing blue energy beams, known as autolasers. Furthermore, the hands can open up and launch spiral grenade missiles. Its chest secretly conceals a plasma maser cannon, a powerful energy weapon. It can fly through earth's atmosphere at Mach 1 and through space at Mach 44. It is also capable of moving on land via independent leg action, or with the treads built into its feet and legs. Moguera is the aggregate form of two vehicles: Land Mogera, a tracked armoured fighting vehicle able to drill through the earth; and Star Falcon, a VTOL craft capable of space flight.

Moguera's first assignment was to intercept SpaceGodzilla, which was discovered on a course toward Earth. A battle ensued in the asteroid belt leaving Moguera seriously damaged, though able to return to Earth for repairs. It was during the repairs that it was fitted with the spiral grenade missiles, and the plasma maser cannon. Following the devastation caused by SpaceGodzilla, Moguera (under its new pilot Yuki Gondo) aligned itself with Godzilla to destroy the greater threat. It shattered SpaceGodzilla's shoulder crystals (thus preventing SpaceGodzilla from absorbing power from crystals), but was damaged beyond repair during the battle; its remains were subsequently obliterated by Godzilla's spiral ray.
Originally, Godzilla was planned to battle Spacegodzilla and a second Mechagodzilla, but it was thought it'd be too onesided for Godzilla to face the same robotic twin that very nearly killed him the year before, so the weaker Moguera was revived as an ally to Godzilla.

Other Appearances
In the ending credits of Godzilla: Final Wars, we see a boy playing with Godzilla plastic-designed figures; one certain figure among the toys was Moguera from the Showa series.
It appeared in one of the Toho website non-commercial cartoons, Retro Moguera, directed by Miles Rilehoff.
Moguera appeared in the TV show Godzilla Island (1997-1998), and was known as "Proto-Moguera". In the "Proto-Moguera Saga", the machine is taken over by the series' villianess and used to fight Godzilla in a bizarre Whack-A-Mole-type conflict.

Trivia
Ironically, Moguera's name is derived from the term Mogura meaning "mole" since it is a robot that is not only used for combat, but for digging purposes as well.
Moguera was the first robot monster in the Toho universe.

M.O.G.U.E.R.A. is the only monster that cannot roar. It only can say it's name. In fact, this attribute makes M.O.G.U.E.R.A. the only giant monster who can say his own name, let alone speak English. It is a reference to Pokemon, as many of them says their names.
As the purpose for M.O.G.U.E.R.A.'s construction was to do what Mechagodzilla had come so close to doing, killing Godzilla, it is quite possible that M.O.G.U.E.R.A. was, or was going to be, outfitted with a G-Crusher system like Mechagodzilla's. Without one, M.O.G.U.E.R.A. would be no more useful against Godzilla then Mechagodzilla was before it was outfitted with it's G-Crusher. However the Spiral Grenade Missiles that are equipped to M.O.G.U.E.R.A. could possibly have been made to preform the same function, as they clearly have the power to penetrate a kaiju's hide when they demolished Spacegodzilla's shoulder crystals.
In a strange way, M.O.G.U.E.R.A. could be considered the "grand-child" of Mecha-King Ghidorah, as it was constructed from the wreckage of Mechagodzilla, who was himself constructed from Mecha-King Ghidorah's wreckage.

Hedorah (ヘドラ Hedora), also known as the Smog Monster, is a fictional character in the 1971 film Godzilla vs. Hedorah. The monster was named for hedoro (へどろ), the Japanese word for sludge, vomit, slime or chemical ooze. He is the main antagonist of the film.

Description
Hedorah is an extraterrestrial kaiju formed from pollution that could feed on pollution. Falling to Earth as a cloud of spores, Hedorah hatched into millions of microscopic tadpole-like organisms which began to feed upon the toxins with which mankind had poisoned its air and water. As they increased in number and power, they began to merge into a giant monster of living sludge capable of reducing the entire planet to an uninhabitable wasteland.
Hedorah's transformations and composite physiology are thought to be the inspiration for the Heisei monster Destoroyah. Surprisingly, Hedorah has become one of the most famous Godzilla monsters.
At the time of his creation, he was without a doubt, alongside King Ghidorah, Godzilla's most challenging enemy. In the course of their fights, the King of the Monsters was continuously injured and found it very difficult to defeat him. Hedorah, with King Ghidorah, Mechagodzilla, SpaceGodzilla and Destoroyah, are considered to be some of Godzilla's most powerful enemies. Although in Final Wars, Godzilla defeated Hedorah with ease, he is still considered to be a powerful enemy of Godzilla simply because of the fact that he was at the wrong place at the wrong time.

Powers and abilities
Hedorah possesses many special abilities. As a composite kaiju formed from millions of smaller organisms, Hedorah is capable of assuming a number of different shapes to suit the particular situation. For traveling through water, Hedorah transformed into a giant tadpole monster similar to the base organism that composed it. For traveling on land, Hedorah became a four-legged pile of slime resembling a gigantic salamander and it also could assume a saucer-like shape which granted it flight capabilities. After being driven back by Godzilla several times, Hedorah assumed a gigantic humanoid shape that even dwarfed the king of the monsters. Thanks to the protean nature of its body, ordinary weapons passed right through Hedorah while even Godzilla's atomic ray was unable to inflict any lasting harm. Finally, since Hedorah fed on pollution, so long as a piece of it remained alive then Hedorah could retreat to absorb more pollution in order to regenerate itself.
Hedorah's primary form of attack was by spurting globs of its own corrosive sludge at its opponent. The slime was so acidic it was even capable of scarring Godzilla's usually impenetrable hide. It was also able to project crimson energy beams from its eyes while its flying form created a byproduct of sulphuric acid mist that melted any living creature that came in contact with it down to its skeletal frame just like the Oxygen Destroyer.

Origins
Showa
Hedorah was an alien life form that landed on Earth and began feeding on pollution. Hedorah's actions soon gained the attention of Godzilla, who attacked the Smog Monster as he was feeding off of a smokestack. At the time, Hedorah was still in a young form, and was easily trounced by Godzilla. The two creatures had a series of battles across Japan, and Hedorah continued to grow bigger and stronger, and achieved a flying saucer-like form, allowing him to fly and spread sulfuric acid mist across Japan while destroying many factories. Hedorah and Godzilla had a final showdown near Mt. Fuji, in which Hedorah achieved his final form, a bipedal, humanoid pile of sludge. Thanks to his acidic, poisonous body, as well as his lethal eye bolts, Hedorah very nearly put an end to Godzilla in their struggle. However, mankind had built a pair of gigantic electrodes near the warring kaiju with the intention of creating a superheated zone that would dry Hedorah out. During a period of the fight where Godzilla was knocked out, Hedorah was lured between the electrodes. Unfortunately, a fuse was blown, and the electrodes were useless.
Thankfully, Godzilla quickly came to the rescue again, using his breath to re-energize the electrodes. Badly dehydrated by their electricity, Hedorah tried to escape when in the film's most famous moment, Godzilla used his atomic ray as a jet to propel himself through the air after the sludge monster whereupon he returned Hedorah to the electrodes to be dried out completely. Sensing still wet sludge within Hedorah's husk, Godzilla proceeded to rip out Hedorah's innards and then used the electrodes to finally slay the last remnants of the polluted monster.

Millennium
In Godzilla: Final Wars, Hedorah, along with Ebirah, is seen being blasted out of Tokyo Harbor by Godzilla and crashing into a building, with one of Ebirah's claws piercing one of Hedorah's eyes. The Smog Monster and the Sea Monster are then knocked out by a blast of Godzilla's atomic ray.

Appearances in other media
Hedorah appears as a villain in the 1988 NES game Godzilla: Monster of the Monsters, as well as the sequel, War of the Monsters. Hedorah was also an enemy in the Godzilla Game Boy title, in which it, along with King Ghidorah, was the only monster unaffected by Godzilla's blows.
Hedorah also makes a cameo appearance in the video game Godzilla: Destroy All Monsters Melee, where it randomly appears in disc form and slows the energy recovery. It can be killed, though this is difficult.
Hedorah is a boss in Godzilla Unleashed: Double Smash.

Gaira
Dwelling within the pitch-blackness of the ocean depth, a powerful green giant lurked. Armed with unquestionable strength and a bloodlust matched by nothing, Gaira showed itself to be a murderous creature. Acting like the right hand of the devil, the ape like creature not only defeated the Giant Octopus, but attacked the very ship that the sea beast was just latched upon. Shoving the vessel beneath the waves, Gaira devoured most of the crew members that managed to flee the boat. Like rats from a sinking ship, they paddled their way through the waves. Unfortunately their efforts would be in vain, as the beast swam after them hungrily. But the monster's belly called for more than just a few scrapes of humans on ships, and Gaira made his way to land.
First arriving at an airport, the sea beast made its presence known to the mainland. After eating a poor woman he snatched up, Gaira finally left as the sun pulled itself from the darkened clouds. Mulling over the destruction, the Japanese military went into action shortly after and set a trap for the beast. Waiting for the right time, the brave men and woman lured the creature deeper and deeper into the mainland. Burning villages and blasting with tanks together forced the creature to the electrified lake. Once he stepped into the sapphire waters the trap was sprung and Japan now had Gaira on the ropes. Electrified with over a million volts of sizzling power, the monster looked that its reign would be over, that is until his brother Sanda intervened. Saving his kin, the twin giants ran. However, it was not long before their differences in regards to human life tore them apart. Realizing that human life meant nothing to Gaira, after gazing at the torn tourists cloths that laid beside the killer, Sanda attacked his brother. However, even in his weakened condition, the murdering beast Gaira was able to flee.
Within a few days the brothers made it to Tokyo and continued their battle where they had left off. Like Cain and Able they fought, each knowing that only one would survive. So intense was their battle, that not even the land could contain their fury. Throwing themselves into the harbor, the gargantuas continued to battle in the ocean's waters. Even the countless bombs that mankind dropped from their helicopters did little to detour their lust. Yet, as fate would have it the bombs trigged an undersea volcano. Erupting with godly force, their bodies were soon engulfed in the flames. Their bodies soon destroyed in the molten fires, burning their images from existence…

Sanda
Dwelling within the mountains, Sanda, the offspring of Frankenstein, lived. Finding peace and solitude in his mountainous lair, the giant grew with love for humankind. As a child, he was found and cared for at Doctor Paul Stewart's lab, where he quickly befriend one of the doctor's aids: Akemi. The warmth of human kindness stayed with the giant, even as it escaped the laboratory. However, blood is thicker than water as they say, and Sanda, upon hearing the screeching cries of Gaira, rushed to his brother's aid. Tearing the electrodes from their generators, the monster lifted, and carried, his kin away from the stunned military.
However, in time, Sanda realized that his brother didn't share his same compassion toward humanity, as Gaira continued to kill and eat innocent humans. The act angered the brown giant beyond anything, sending him to attack his bloodied brother with malicious hate. The green gargantuan was sent into retreat from the assault, running straight to Tokyo, traveling through the dark waters of its harbor. Citizens ran in fear from the killer, until Sanda arrived again. Pleading with his brother, the brown gargantuan tried to get his kin to turn away from civilization, but the call went unheard and the two giants fought.
Dragging their battle into the ocean, both of the monsters were destroyed in an undersea volcano. Taken by a power greater than their own.
