A sentient and constantly evolving neural parasite hosted by Al Simmons once he became a Hellspawn. Made of necro-plasm, Hell-born parasites like K7-Leetha bond for life with their host's central nervous system. Daughter of the 7th House of K, K7-Leetha's name is first revealed in Spawn Blood Feud Issue #1. A similar neural parasite, K3-Myrlu, bonded with Billy Kinkaid before he entered the Malebolge.
