IG-88 B

Constructed at Holowan Laboratories, IG-88 B was a counterpart to IG-88s A, C, and D and possessed the same capabilities. A "family" of four, each droid shared a collective conciousness as well as a goal of galactic conquest. The IG-2000 is IG-88 B's modified Trilon Agressor assault fighter. IG-88s A, C, and D fly identical ships. Of the four, it is the droid designated IG-88 B that accepts Darth Vader's assignment to track down and capture Han Solo.
