"Encephalon" is a demon which was created apparently out of nothing by the powerful demon Blackheart. Encephalon was one of four villains (known collectively as "Antitheses"), all of whom were created by Blackheart to be the opposite of the dark heroes he was facing: Venom (Flash Thompson), Red Hulk, X-23, and Ghost Rider (Alejandra Blaze).
Encephalon, who was essentially a giant and powerful brain, was created to be the opposite of the brawny Red Hulk.
