Hollow Ynot, abbreviated HY, is Ynot's split personality. How he came to be is not known. He usually only surfaces when Ynot is taking a major beating and all else has failed. The shift to him is usually indicated in Ynot's eyes, as they change from their standard to black and yellow. To a further extent, if he REALLY starts to take over a bone white mask with red markings will cover his face.
