IG-88B

One of the four identical, sentient killing machines of the IG-88 line. It was agreed by all four of the units that this one be chosen as a bounty hunter, as to distract any attention from Mechis III where the droid revolution was being conducted. It was this one that was onboard the Super Star Destroyer Executor during the hunt for Han Solo. While onboard, it learned of the new Death Star project underway at the forest moon of Endor. It relayed the information to the other three IG-88's. Afterwards, it started placing trackers on all of the bounty hunter's ships that were present, he would use them to find Solo. Boba Fett wasn't tricked by this, he allowed IG-88B to follow him to Bespin, where he ultimately fries the assassin droid. IG-88B was left as scrap in the bowels of Cloud City.
