IG-11 is an IG-series assassin droid created for The Mandalorian (2019) and voiced by Taika Waititi. He is introduced as a rival bounty hunter on the job that opens the series, is destroyed within the first episode, and is rebuilt by the Ugnaught Kuiil as a nurse and protector.
The rebuild is the point. IG-11's defining trait as an assassin is his self-destruct protocol — he will not be captured — and the second half of his arc turns that same absolute, unhesitating logic toward keeping the child alive. The droid does not change. Its instructions do.
He is the first IG-series unit the franchise has ever given interiority to, forty years after IG-88 stood silently in a line-up in The Empire Strikes Back. He returns, reconstructed again, in the series' third season as a marshal on Nevarro.
