Known History: In 2008, A.G.M.U. II (Anti Giant Monster Unit) was built with state of the art technology and the most durable of materials in order to fufill a near impossible task: kill a giant monster.

The first assignment issued to this mech and its team was to drive away or kill the creature known as Rhinosaur [link] , which at the time was the scourge of Seattle, Washington. Using missles designed to pierce even to toughist armor, A.G.M.U. rendered Rhinosaur "unconscious", reinforcing the belief that A.G.M.U. was quite the weapon.

A few yeas later, this unit was upgraded thanks to the help of the extraterrestrial known as The Keeper, augmenting his weaponry and transportation systems, giving him the ability to fly.

Eqiupment: Originally built by the World Self Defense Force (WSDF) from reversed enginereed tech from the corpse of Mecha-Borodan [link] , A.G.M.U. has a claw on its left arm that is able to generate 200 MV of electricity. On the right arm is a missle launcher, designed to harm even the strongest monster.
