- "We think, therefore we are. Therefore we will propagate. Therefore we will remain."
- ―IG-88B and IG-88A in unison upon B's activation
After IG-88A gained "sentience programming" and killed much of the Project Phlutdroid personnel, IG-88B was activated, named by order of activation, and given the same sentience programming from the first unit. With the other IG-88s, as well as IG-72, the five droids managed to escape the factory and leave a swath of destruction in their wake.
- "Mission accomplished. First objective completed."
In 5.5 BBY, IG-88B, on a mission to kill Olag Greck in the Kalarba system, encountered C-3PO and R2-D2. The bounty hunter was captured, but escaped and held R2-D2 and C-3PO hostage. He was known as the second best bounty hunter in the galaxy—second only to Boba Fett. IG-88B piloted a modified Aggressor assault fighter named the IG-2000.
IG-88B played a crucial role in the planned Droid Revolution on Mechis III by being the main bounty hunter "face" of the group. He took jobs that often required massive amounts of destruction, in order to further lead pursuing Imperial forces away from Mechis III. He was the unit who was contacted to capture Han Solo by Darth Vader, who, despite being quite aware of the "dismantle on sight" order concerning the assassin droids, valued the capture of Han Solo too much to be concerned with the risks involved. While on board Vader's ship, the Executor, IG-88B downloaded some of the ship's computer files, including information on the second Death Star, which he transmitted to IG-88A, before departing. He then planted a tracer on Slave I and followed Boba Fett to Bespin, intent on killing him. There, he followed Fett to the bowels of Cloud City, where he walked straight into a trap set by Fett. Four remotely activated ion cannons fired on IG-88B when he walked through a doorway. Boba Fett then shot him with a shoulder-mounted ion cannon, knocking him to the floor. He extracted IG-88B's own concussion grenades and placed them inside the droid's metal casing. IG-88B was blown apart from the inside.
Behind the scenesEdit
In the Jedi Force File booklet accompanying IG-88's Hasbro Power of the Jedi action figure released in the year 2000, IG-72 is listed among the droid's allies. The accompanying image is from the scene in the Cloud City incinerator room on Bespin in The Empire Strikes Back, where a damaged IG body can be seen. However, 1996's Therefore I Am: The Tale of IG-88 had previously established that this IG-88 model was in fact IG-88B. Likewise, the Rebellion Era Campaign Guide states that IG-88B was "blown to pieces" by Boba Fett but not to what extent.
An assassin droid in reference to IG-88B is featured in an easter egg in Star Wars: The Old Republic. He is featured along with the other bounty hunters and Darth Vader from the Bounty Hunter scene of Empire Strikes Back.[source?]
