black uruks

The Black Uruks were extremely rare, elite Uruk-Hai, and possibly the greatest orcs Sauron ever had in his armies; made after his diminishing at the end of the Second Age, even before his return to Mordor.

 

An advanced breed of orcs that serve Sauron and Saruman. The first uruks appeared out of Mordor in attacks on Gondor in T.A. 2475.
