Expugs wear a form of exoskeleton for the upper body. It serves as armor, but most importantly, it connects with their helmet when expugs ram their enemy or obstacles. Seen from the back, their helmet looks like the beak of an eagle – or an anvil – pointing towards the sky.
Their armor incorporates thrusters which accelerates them towards their targets when ramming. There is a weakness. There is a rod running along their leg. The leg pointing forwards when in shooting or fighting position. The rod is joint at the knee and attached to the knee and ankle. This rod is detached when they ignite thrusters and armor and helmet connect. The rod is a grounding mechanism. If it does not touch the ground, then the guidance system of the armor malfunctions and the expug will fly in a random forward direction.
