TecSeks were modeled after the Xenomorph. They are bipedal, digitigrade automatons with a silvery-white chassis. This metal is acid-proof and resistant to other elements, such as fire and explosions. A yellow visor acts as the "eyes" of the robot. They have clawed hands and feet and alone their spines are dorsal tube-like appendages they are configurable and can be weaponized. Two plasma weapons are mounted on each shoulder and they lack tails.
They are roughly the size of a Queen, perhaps 2 or 3 feet shorter.
