Urdnot Wrex is a fictional character in BioWare's Mass Effect franchise, who serves as a party member (or "squadmate") in the first game of the Mass Effect trilogy. He is a krogan, an alien race near-sterilised by other galactic races for their violence and high population growth. Introduced as an experienced krogan mercenary, his role changes in Mass Effect 2 and Mass Effect 3 where he becomes leader of an expanding krogan clan and eventual head of state for the krogan as a whole. After over 1000 years of aimless apathy, Wrex seeks to bring back hope to his people and reverse their fate by undoing the genophage. He is voiced by Steven Barr.
