The IG-86 sentinel droid was a model of sentinel droids manufactured by Holowan Mechanicals as a subsidiary of Holowan Laboratories, the same company that created IG-88. It was designed to function as a bodyguard, or home security system for the wealthy, but was usually used for more sinister purposes.
IG-86 sentinel droids were similar in appearance to the earlier IG-series droids such as the IG lancer combat droid. Considered to be some of the deadliest droids in the galaxy, they were more intelligent and agile than standard battle droids, able to think logically and creatively. They were capable assassins working individually or in groups.
