Whenever someone orders a McBAT from the MARS corporation they always ask "Do you want Small Fries with that"?. The McBAT's are self sufficient, but in battle they are accompanied by these less imposing ammo carrying and repair robots. They have no weapons and no real armor to speak of. They wouldn't even be a problem except they are cheap to produce and make the McBATs even deadlier. Take one out and another one will come to take its place.
This figure came about as a fun, tension relieving side project for the horrors of making the McBAT. I put the helmet on the art doll figure and thought it kind of looked like Twiki from Buck Rogers.
