Whiles trying to develop smarter weaponry, the military tried to fuse people with machinery to create cyborg weapons but the process usually proved too much for the subjects and the mental strain and anguish killed most of them after seeing what they had become.
It was devised to cut off signals to parts of the brain in order to literally 'programme' them, combined with the plan of just using the mind instead of a whole human body, the bodies in which these new minds controlled could be any size, shape or form and so the battle pod was born. A quadrapedial structure (more stability on four limbs as past tests showed that some neural instability caused balance issues and many earlier machines toppled) with multiple plasma based weaponry and signal antennae.
However, this progress didn't last as they soon began to build up electrical charges within their brain cases (an inner case for the brain to keep it safe whiles feeding nutrients, and an outer shell for primary defence) and this drove them to insanity. The new 'crazed' battle pods turned on everything that wasn't another battle pod and served as the vanguard for a new race of neural cyber-organic weapons.
Bought the TMNT Kranng Lab Escape mainly for the dome as I'd been thinking about mechs and submarine type builds with it. My first experiment yielded these results. A fairly simple little system pod with a centre brain and a mechanical form.
