The Jimmy is a twiggy humanoid robot with an armored chest plate that has much of its machinery showing on its lower body. Ze-J1 droids are built on steel alloy skeletons and their chestplate and faceplate are made of fullerine. They're slightly stronger and faster than the average Nepleslian or Human. Its head has a slightly V shaped eyepiece that conceals its optical system.
The Jimmy possesses a somewhat rudimentary intelligence, focused on basic infantry tactics. They can't really carry on a conversation, but they can follow orders; they communicate by audio or via radio. The Jimmy almost always carries a rifle. Jimmy robots currently ship with a Zen Armaments 10mm Submachine Pistol, but can utilize any weapon a human can hold.
The Ze-J1 is battery powered. It can operate at full capacity for up to 48 hours. A hydrogen fuel cell system (an optional part not all Ze-J1 droids have) can extend their operation to two weeks. They aren't power intensive machines.
Cost: 250 KS each. Available through the black market.
These are fairly generic battle droids, kind of like the common ones in the newer Star Wars ™ movies. They're not super tough - basically something for the PCs to fight, where large numbers of them wouldn't be necessarily ultra-fatal.
