Fake Godzilla

Fake Godzilla (にせゴジラ Nise Gojira) is a doppleganger kaiju who appeared in Godzilla: Lord of the Galaxy.

When the Xiliens came to Earth to attack and enslave humanity, Fake Godzilla was dispatched to frame the real Godzilla by attacking a city. The Xiliens "saved" the day by sending out a wave of energy that led Fake Godzilla to flee to the ocean. Underneath its disguise, is a metallic Titan that was built in the image of Godzilla called Mechagodzilla.

Name
The "fake" in Fake Godzilla's Japanese name is sometimes spelled in either kanji (偽), katakana (ニセ), or hiragana (にせ) characters, though all of these spellings are pronounced "nise."

Design
Fake Godzilla retains the same design as Godzilla in Episode 1. However, one key design choice is that his eyes glow whenever he is transmitted a signal.

History
Godzilla was seen attacking Shizouka after the humans have made contact with the Xiliens where he was seen destroying the city. The Earth Defense Force (EDF) launched planes and cannons to fire him with cadmium missiles, but to no avail. They then tried to shoot down Godzilla with Masers, with the bigger, Hyper Maser Cannon managing to cut Godzilla's skin, and with their shield, could not be damaged badly by Godzilla's atomic breath. Suddenly, Godzilla let out an Electromagnetic Pulse which disabled the Maser Cannon's shields and masers. The planes had the same issue, with their weapons and shields out of commission as well. Godzilla shot a plane out of the sky and torn the larger Maser Cannon with his hands. Suddenly, another Titan entered the city.

Anguirus confronted Godzilla and after a stand-off, he blew Anguirus off-guard with his atomic breath. Anguirus, realizing something was wrong, fought Godzilla head on. With support from the EDF, Anguirus was able to wear down Godzilla well. However, he couldn't take him out, and after a wrong move, Godzilla managed to bite his neck and make him bleed. Anguirus retreated after unsuccessful taking out Godzilla.

A UFO (the one that contacted the EDF) supposedly scared away Godzilla with a ray. The Xiliens then told the humans that a new monster will emerge and destroy the world.

Two scientists, Tom and Polly, have "telepathically" arrived at Infant Island, at which the Shobijin said that the Godzilla that attacked the city was not actually Godzilla; it was an impostor. The real Godzilla was trapped inside the UFO for 2 weeks. To make things better for the humans, there was no radiation in the area where Godzilla supposedly blasted his atomic breath, as the Godzilla species cannot survive without absorbing and exhaling radiation, exposing the aliens.

During the end scene, Fake Godzilla was sent a transmitting ray which made his eyes glow.

Blue Heat Ray
Fake Godzilla possesses a beam that has the destructive capabilities of his real counterpart. The only major difference is that fact that there was no radiation from it. The Xilien master planned to implant the nuclear reactor, but the Xilien commander said it would've been a waste of time.

Electromagnetic Pulse
Fake Godzilla was able to let out an Electromagnetic Pulse, which disabled the EDF's weaponry and shields, however does not disable the mobility power, hence why some planes and cannons were able to escape.

Physical Strength
Fake Godzilla possesses incredible physical power. The jaws of Fake Godzilla were able to make Anguirus's neck bleed and easily tore a maser cannon apart. It was able to hold its own against its fight against Anguirus and prevailed, even coiling Anguirus around the neck with its tail and tossing it toward the other side.

Durability
Fake Godzilla withstood the EDF's maser cannons, however the large Maser cannon was able to pierce its skin. It managed to hold its own against Anguirus, able to survive tail blows and stomps.

Radio Receiver
Fake Godzilla can receive radio waves that contain orders from the Xiliens. When doing so, his eyes flash yellow.

Weaknesses
Fake Godzilla cannot unleash its full arsenal, due to its disguise. Also, his skin is still vulnerable to powerful convention weaponry and can be punctured through as well.

Trivia

 * There is a notable difference when Godzilla and Fake Godzilla fires his Atomic breath. When Fake Godzilla shoots his breath, his entire dorsal plates lighten up. But when the real Godzilla uses it, only "lines and cracks" of his plates light up.
 * The Fake Godzilla vs Anguirus fight has notable references. Godzilla tail wacks Anguirus when he curled into a [wrecking] ball, like he did in Final Wars. Anguirus has a supersonic roar, like in Godzilla Raids Again and the Atari games. However, the entire fight scene is a reference, because Anguirus fought Fake Godzilla, just like in Godzilla vs Mechagodzilla.
 * In a deleted scene of Episode 1, Anguirus's tail club sliced Fake Godzilla's skin, revealing metal underneath.
