A Nuppeppo; appearing at midnight in ruined temples or near graveyards–a chunk of dead flesh walking by itself.

A barely discernable humanoid head and a pair of pseudopods are the only appendages on what is best described as a heaving mass of red clay and mud. Aside from pock marks and dents where the eyes and nose should be, the head is featureless. Indeed, so too is the entire form. From time to time, it seems as if something buried beneath the creature’s mass struggles to pushes free. As it reacts to your approach, shuffling aggressively towards you, whatever lies within the creature becomes even more animated.

A misshapen, damned being native to the Nine Hells of Perdition. Bearing a passing familiarity to the better known lemure and sharing many of the same duties, the nupperibo is even more detested by the devils of Hell than its lower ranked cousin. Interestingly enough, it can never be promoted into another form of devil; instead, it must be demoted to a lemure in order to progress. Even more intriguing is the fact that cornugons, gelugons, and pit fiends do all they can to ensure that they never advance beyond 9 HD; conversely, barregons often attempt to secretly coral dozens of nupperibo secretly in order to allow them to advance to 14 HD.

At about 5 ½ feet tall and weighing about 250 pounds. Blind, deaf, and mute, a nupperibo is susceptible to telepathic messages from other devils.

Nupperibo are shambling, ambulatory meat sacks – vaguely humanoid blobs of pus and flesh with a putrid yellow-green pallor – with the horrified faces of the accursed damned. Damned souls raised from the Styx to do the bidding of the princes of Hell, nuperribo are largely mindless and attack in mobs with found weapons or slashes from their rotted claws. They stand five feet tall and weigh about 100 pounds.

Devils constantly punish these tortured spirits, which they consider even lowlier than lemures and manes. They are used as fodder in their never-ending wars, with a typical nupperibo army consisting of thousands of these creatures. Nupperibos unerringly follow the orders of their commander. They are relentless in their pursuit and attack and continue to assault anything in their path until ordered to stop by their commander. A nupperibo killed in battle is 99% likely to be reformed (by a duke or arch devil) into another nupperibo; the remaining 1% are “promoted” to lemure status, having proved their worth in combat.

It is dedicated to physically harming and oppressing other creatures. Although utterly mindless, it is instinctually driven to attack those creatures unassociated with Lawful Evil. It will attack any non-devil as soon as it is aware of such a creature’s presence and can only be stopped by being destroyed or order to cease by a devil. Needless to say, it has no strategy or tactic other than to seek and destroy.

A nupperibo’s natural weapons, as well as any weapon it wields, are treated as evil-aligned and lawful-aligned for the purpose of overcoming damage reduction.

Burning Strike (Su): Its slam attack leaves behind a slimy residue that eats through the flesh of those it strikes. Creatures struck by the nupperibo’s slam take one-half the damage the following rounds for a number of rounds equal to the its Constitution modifier (one round for the average nupperibo).

Metamorphosis: A nupperibo that is left on its own will continue to advance, eventually beginning a metamorphosis into something greater. For every HD beyond 9 that a nupperibo advances, it gains a 1 point increase to all of its mental ability scores. It loses the Mindless trait and replaces it with telepathy 50 ft. The nupperibo also begins dealing 1 point of Wisdom damage on its slam attack. Nupperibos of 12 HD and greater grow vestigial wings, developing a Fly speed of 20 feet with poor maneuverability.

At 14 HD, a nupperibo gains the spell-like ability greater teleport (self plus 50 pounds only) at will. It should be noted that very few nupperibo survive to evolve that far. Usually they are demoted into lemures long before any of these changes can take place.
