IG97 & Rom Mohc
"Rom Mohc is an Imperial general involved in the testing of advanced battle droids known as dark troopers. One of these droids ends up on Tatooine and becomes activated by scavenging Jawas. The dark trooper attacks three friends camping in the desert. But things change when the prototype encounters a clumsy IG97 battle droid on Tatooine, and the two machines battle each other.
