T'evgin is an Omec, an eighth alien race. The Omec are all kinds of badass, having been the overlords of all the other alien races (Irathients, Castithans, Indogene) before everyone fled their dying universe to come to Earth. T'evgin is their leader, so you really don't want to mess with him. Some poor fool probably will, though.
