Hau-karas's Army

Hau-karus holds the secret of necromancy and quite a lot of mummies, golems, zombies, and skeletons. His aura of fear helps him in negotiations, but demons tend to be resistant to it.

King Ovnunu

The Ovnunu are a big force, and King Ovnunu commands a lot of them. He is one of the members of the Demon Council, the equivalent of the U.N. but with more squabbling and power ambitions.

Lord of the Ice Castle

The Lord's pesky control of weather patterns is what makes others fear him

Puncher's Gym

Puncher's Gym is not entirely a major force, and they do not fit in the Demon Council, but they do have some control, because they hold a monopoly on proper hand-to-hand training.

Technodem

Technodem is not a malevolent nor incredibly powerful force, but he does hold the monopoly of technology in the Demon Realms. His technology, in some areas, is equal to or better than the Company's or the Chaos Temple's. Thus, he is the newest member of the Demon Council, and is feared by many there. His great diplomatic advantage is that he sells to all of the forces, and this also makes him a lot of money. Although each force would like him to sell exclusively to them, they also would fear the retribution such an act would make towards them.
