Crius was a Titan who had a relatively favorable view of humans more. He was one of the many titans turned to stone when the Olympians won the war against them ages ago. Crius was released by Gabrielle and was later killed by his brother Hyperion over a disagreement over humans. (XWP: "The Titans")

Another Crius, or possibly the same one in a different form, was a wind Titan. This version appeared to be rather dim and seemed to be romantically linked to Mnemosyne. He is dark blue in color, with a light grey underbelly and hands and small horns. In some scenes he is portrayed as having a pot belly and in others he is in relatively good shape. His form is later altered by Hera, giving him large wings, a VERY loud scream and more wind related abilities, this transformation leaves him, as more of an animal than the others, walking on all fours and speaking in only screams. He is the least reluctant of the group to accept these new forms, actually going so far as to say in his sleep "no, I dont want to change". He is the first of the group to be thrown into Tartarus.
