Zombot

The Zombot is pretty much exactly what it sounds like; a robot, except on wheels. A rifle is seen being held by said robot. The casting has a unique ability that allows it to stand up on its two feet without falling over. In 2017, the tooling for the Zombot was changed; the base and machine gun were altered, with the machine gun being a full piece sort of integrated into the body and riveted to the base.
