Thuris is the second World Eater that Revya encounters and is, physically, the weakest of the three. He has the ability to become invisible. Following the defeat of Gig, Thuris created the Cult of Thuris by leading his followers into worshiping him as a god. When Gig converses with him, he tells Thuris that he had become more like a human. Later on in the story, he reveals that it was he who brought the plague of Scarlet Iago upon the world. Gig describes him as the most intelligent World Eater and the one he disliked the most. Before the second battle, Thuris reveals that he was the one who brought back Scarlet Iago to the public 15 years prior to the story, at which Kanan first made contact with him. He taught his followers how to create it and spread across the land, setting up Shauna's and Trish's separation and Shauna's hatred for everything. Upon his defeat, Thuris commits suicide by blowing himself up and spreading the disease Scarlet Iago as a result.
