Mechagodzilla

Mechagodzilla (メカゴジラ Mekagojira) is a mecha Titan that was shown in the Godzilla: Lord of the Galaxy teaser.

Mechagodzilla was sent here by the Xiliens as an imposter to frame the real Godzilla, and was wearing a disguise, dubbing it Fake Godzilla.

Name
The name "Mechagodzilla" comes from "mecha," which is derived from the word "mechanical," and Godzilla's name."

Design
Mechagodzilla's design was based on Kiryu and Ready Player One Mechagodzilla.

Episode Two - The Impostor
Mechagodzilla will fight Godzilla as Fake Godzilla.

Abilities
Mechagodzilla retains same abilities as Fake Godzilla, however he can unleash all of his weapons due to his exposed metallic body.

Blue Heat Ray
Mechagodzilla possesses a blue heat ray that is comparable in power to Godzilla's atomic breath. It's impossible to tell the difference between these abilities by apperance. However, Mechagodzilla's beam doesn't leave radioactive traces, which ultimately called the EDF to dub this "Godzilla," an imposter.

Electromagnetic Pulse
Mechagodzilla's electromagnetic pulse can disable EDF's shields and prevent Godzilla from using his Atomic Breath.

Physical Strength
As a mechanical Titan, Mechagodzilla is incredibly strong and is capable of overpowering monsters like Godzilla.

Durability
While the Mechagodzilla's fake skin was much softer than Godzilla's and could've been damaged by Hyper-Masers, his metal body is composed of Space Titanium and is incredibly resistant to damage.

Radio Receiver
Mechagodzilla can receive radio waves that contain orders from the Xiliens.

Trivia

 * Mechagodzilla staring into Godzilla's eyes was an unintended reference to when Mechagodzilla was going to kill Godzilla in Godzilla vs. Kong.
