From Halopedia, the Halo wiki
Tukduk was one of the sixty Unggoy who were assigned to the Jiralhanae-controlled cruiser Rapid Conversion during the First Battle of Harvest. He had only one eye, and had numerous scars, a hint that he was a battle hardened veteran, or perhaps just rowdy among his fellow Unggoy.
Along with Guff, Tukduk was essentially a toady of Flim. He and Guff were assigned to Flim's post on the Tiara, orbiting Harvest. The three had a rocky relationship with Dadab, Rapid Conversion's Deacon, during their time on the Tiara. Later, Tukduk, Flim and Guff began looting human containers looking for food and Forerunner artifacts.
During the human attack on the Tiara, Tukduk was among the Unggoy who held out the longest, but eventually fell to the human onslaught.
