V-004 may appear to be a large robotic insect at first, but this is incorrect. The real V-004 is a small cat creature, which operates the robot from inside its head. The creature rarely reveals itself and makes sure the coating on the cockpit (which can change opacity) is always working. 

V-004 gets nutrition via an interesting mechanism on the robot, and its primary function. The robot is built in a way that it can "eat", which simply brings food into the cockpit so V-004 itself can eat. The robot swings its tail at prey, impaling it on the sharp end of the tail. It would then bring the dead animal up to its mandibles, where it would cut it to pieces and bring it to the cockpit via several brushlike objects in the center of the space between the mandibles. It grips prey items in its claws while doing this.
