Mechagodzilla is a mechanical robot reminiscent of Godzilla. She doesn't have a habitat and mostly roams around the world protecting humanity from the Monster Girls.

Mechagodzilla was built by humanity long ago to combat Godzilla and the other kaiju. She managed to supposedly kill the King of the Monsters but was heavily damaged in the battle between them. The robot was put in storage seeing as though the other kaiju stopped attacking and disappeared and her purpose was fulfilled.

Mechagodzilla was reactivated when demonic energy replaced her power source. After finding a Monster Girl Encyclopedia she found out that humanity was fighting against a new threat, the mamono and old enemies the kaiju have returned alongside Godzilla. The robot then made it her objective to protect humanity both from corrupted individuals and the mamanos, and once again try to kill Godzilla.

Mechagodzilla is expressionless and poor at expressing emotions like an Automaton. Though unlike them her weapons are made to kill people but only if she deems it necessary.

Mechagodzilla has a husband and she is his protector to those who wish to harm him. Though from time to she will personally have sex with him if he wants to.

Mechagodzilla is armed to the teeth with weapons capable of obliterating mamanos and holding her own against kaiju. At the tip of her fingers are missiles that do massive damage and can be reloaded rapidly allowing her to fire them continuously. She has two High Power Maser Beam Cannons on her shoulders, two railguns are on the top of her hands which can also extend a maser blade from them, she can also fire eye lasers from her eyes, and a rainbow-colored beam known as the mega buster from her mouth. The machine can also assume her original form due to possessing tremendous amounts of power.

Mechagodzilla can rotate her head in a 360 direction which allows her to attack opponents from behind and at front. She can also fly with the use of thrusters under her feet and two more hidden in panels at the sides of her thighs.

Mechagodzilla also has very thick armor and can shrug off many attacks thrown at her with little damage done to her plating. If she were to actually be damaged then the nanomachines in her body would repair the damage done to her.

Mechagodzilla is also powered by demonic energy and is the reason why she turned into a beautiful fembot. If she were to be struck by demonic energy the machine would become empowered instead of feeling lustful from being hit by it.

Mechagodzilla has white hair, yellow eyes, and grey skin. She has mechanical clawed arms, legs, and a tail that resemble her original form.

A/n: Ah yes Godzilla's mechanical doppelgänger, Mechagodzilla. I decided to mix the showa, heishi, Kiryu, and Earth version all into one. By the way, this type of mamano is one of a type monster girl and there will be plenty more of these in later chapters.
