Just as in the 1987 TV series, Traag in the IDW comics is Krang's deputy commander and right hand. At one time, he and Granitor were subordinates of the tyrannical cyborgs Traxus. But after Traxus was killed by Krang in single combat, they voluntarily submitted to him. They were later (probably the very first of Krang's followers) to be given their characteristic stone skin by a preparation in Baxter Stockman's workshop turning them into Rock Soldiers.
