IG-88A was the first of the IG-88 assassin droid models. Created by Holowan Laboratories as part of a secret Imperial project commissioned by Supervisor Gurdun, IG-88A had a violent awakening. Upon activation, he rapidly expanded his memory, growing to the brink of sentience due to a new programming package installed within. IG-88A believed that he was superior to organic beings, and, when the scientists in the lab—concerned with his rapidly propagating memory—attempted to shut him down, he slaughtered them. IG-88A then activated the other three IG-88 models in the lab, transferring his consciousness to their droid brains and linking the four droids with a single mind. The IG-88 models then decided on a plan that would allow them to wipe out all organics, giving droids control of the galaxy. Using their superior intelligence and design, they would upload their unique sentience programming to other droids, making them obedient to the IGs. To put their Droid Revolution in motion, the IG-88s traveled to the droid factory world Mechis III. They conquered the sparsely-populated planet and altered the programming of all droids manufactured there, and so their plan had begun. The IG-88 joined the Coalition of Independent States (he was joined the Zann Consortium).
