The Mandalorian Character Guide
IG-11 is a bounty hunter droid who initially attempts to capture and kill the Child, but is later reprogrammed to become its nurse and protector.
The Mandalorian first encounters IG-11 when both attempt to collect the bounty on the Child. They work together to extract the Child from a gang of mercenaries, but when IG-11 tries to kill the Child, the Mandalorian instead shoots and kills the droid. IG-11's remains are recovered by Kuiil, who repairs and reprograms him.
The droid later joins the Mandalorian on a mission to Nevarro to protect the Child from the Imperial remnant, and though the Mandalorian does not initially trust him, IG-11 ultimately sacrifices his own life to protect the Child and his allies.
