Monster Name: B-Class Cyborg
Physical description: humanoid figure, much larger than the average human. The B-Class is the second mechanical transplant of human consciousness to be utilized for combat. Consisting of soldiers who opted for the experiment after suffering loss of body functions due to various injuries, these cyborgs are the domineering forces of Earth's infantry. They share a communication disk in their brain that alerts them to any orders from HQ and possess some independence and creativity, which makes their assaults on the enemy open to diversity.
Additional abilities: the body uses an advanced flexible lead core that grants immunity to radiation and also utilizes state of the art technology that makes them immune to explosions and hazardous gases.
Weapons: brute force, Arsenal of weapons ranging from a standard infantry rifle to an advanced Davy Crockett style RPG depending on placement in the infantry. Nanobots ensure transmissions from the conscious "brain" are able to control the machine.
Background details: After the ability to transfer consciousness from a body to a machine was discovered and made available to the military, the growing issue of injured veterans not being able to fight in war was solved by giving them a new body. After incredible successes with the A-Class Cyborgs, the B-Class was issued for everyone who opted to use them and met qualifications (exceptional skills in combat and injury that prohibits their use)
Weakness: Acid attacks can destroy much of the cyborg mechanics, causing malfunctions that lead to immobilization and system failure. Radio transmissions can disrupt the nanobot signals, leading to system failure.
