Belial is a fallen angel—and one of the first primal beasts ever brought into being.  He is the manifestation of cunning, earning him the sobriquet "Serpent."  He plays dirty and is irreverent, and his mind swims in the gutter. The only man he respects is his own creator, Lucilius, to whom he has given the pet name "Cilius."

But recently, the Singularities Gran and Djeeta have managed to catch Belial's eye.  Toying with them gives him a visceral thrill.  He loves nothing more than to sow chaos with Exia, then watch Gran or Djeeta struggle to restore order.
