Jacques Tenebrae is the host body of Apelpisia, also referred to as the Demon Shape. Jacques sans Demon Shape is the future part of Behemoth, and the Demon Shape is created using Jacques' body by the Princes of Hell. When first created, Apelpisia was an unstable being and nearly destroyed its host body, therefore the Demon Shape was forcibly put into hibernation by the Princes. Jacques was cast off to Lucifer's realm, where he and his parasite started a symbiotic relationship. The next time they entered Separ, the Demon Shape culminated and turned its relationship with Jacques back into full-on fusion, albeit a more stable one due to the both of them having grown accustomed to each other. From this point on they are considered to be one being.
