Xenocite is the strongest of the Four Cites and is the natural leader. He has a brother/sister relationship with Genocite, who is almost as strong as him. Xenocite has a thing for Suicite, but doesn't openly admit it for most of the BSSC season. It isn't until a visit from Homocite, his future son from the 31st century, that he confesses his love for Suicite.
