Crius was one of the Titans, who favoured humans more. He was restored from stone form by Gabrielle and later killed by his brother Hyperion over a disagreement over humans.
Crius is a wind Titan, he is portrayed as being extremely stupid, and somewhat 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 don't want to change". He is the first of the group to be thrown into Tartarus.
