Zen Daemons are Inter-species Hybrids consisting of genes from a Daemon, and one other species, most commonly are those bred with a human female and a daemon male, most births leading to the mother's death 90% of the time. Being born with both half daemon and other species genes, it leads to instability of the mind and physical form; their bodies are constantly fluctuating between the two species, but make for very powerful weapons and adversaries.
