Malachai "Kai" Parker was a siphoner-vampire hybrid that was the son of Joshua Parker and his wife, the twin brother of Josette, and the older brother of Olivia, Lucas, Joey, and three other siblings. When his nature as a siphoner was revealed in adolescence, his family began to treat him poorly and referred to him as an "abomination," which, led to him being a sociopath and killing most of his family. Kai is a very handsome and charming man with dark brown hair, blue-grey eyes and a slim build.
