The Rydraxian

The Rydraxian is deployed from orbit when the occupied planet's future habitability is no longer of concern. In it's right hand is a plasma torch capable of burning nearly anything into glass and even triggering fire storms. In its left arm is a rail gun capable of shooting down a star cruiser. And in its center is a rotary gatling cannon able to deliver 1000 rounds a minute each with a mass disconcertingly close the that of a car. It's shear mass is so great it must rely on tensor fields and anti gravity mechanisms to carry its own weight.
