Dyitzu are the most commonly found devil in the labyrinth, though how they replenish their numbers is as yet unknown to us. Dyitzu range in size from around 4 feet on the small end to as large as 7 1/2 feet. It is unknown if the smaller breed are true Dyitzu or just a large version of Pigmydytz. Variation in color also exists, ranging from a brighter, stereotypical devil red to a shade more akin to that of dried blood. Some have a more hunched, ape-like posture, while others stand as humans. Stunted wings protrude from their back, though they are not capable of flight. Their five fingers taper off into sharpened claws and, like us, they have opposable thumbs.
While not technically a compound eye as images are not delivered to the dyitzu’s brain via tubes, the dyitzu eye works under similar principles. There are no lenses or pupils to speak of, giving the dyitzu eye surface a glossy red appearance. Focusing appears to be an act of mental calculation. Dyitzu tend to communicate with each other through hisses and grunts. This communication is thought to be roughly analogous to a wolf pack’s on old Earth. Dyitzu sense of smell, while oft purported to be superior to a human’s, is not noticeably so. Kent performed several tests and found that human olfactory experience seemed to be slightly sharper, although he warns his tests might have been colored by the fact that the dyitzu were not highly motivated as test subjects.
The most significant danger when encountering a dyitzu is its ability to throw fire. The fire generates out of seemingly nothing, is not affected by gravity, and travels in a straight line at a constant speed until acted upon by another force. However, the dyitzu can make them curve by throwing the fire with a spin in much the same way as a baseball pitcher. This does not conform to old earth rules of physics, as air resistance does not appear to affect dyitzu fire. The combustible substance of the fireball is liquid, which splatters upon impact. After impact, the dyitzu fire will burn for some time. If possible to capture and extinguish, this liquid makes an excellent fire source.
Minotaurs, if they so choose, can cause other characteristics in the dyitzu to express themselves. One such expression is known as the dark dyitzu whose wings are fully developed. Such dyitzu are capable of flight and their wings can double as a shield against bullets. These dyitzu seem to have a higher level of kinesthetic intelligence, perhaps correlated with the additional coordination needed to fly and have been observed to throw multiple fireballs at the same time with a higher degree of accuracy than their dyitzu cousins. When dissected, the dyitzu’s medulla oblongata and hippocampus are much larger and denser than on a normal dyitzu. Dark dyitzu tend to be of darker shades. It is not known if this deeper pigmentation occurs during its metamorphosis or if minotaurs are simply more likely to pick darker dyitzu for the transition.
A second expression is commonly called high dyitzu. These dyitzu are capable of human speech and are notably more intelligent than their plain counterparts. They often lead dyitzu packs. When high dyitzu brains are dissected, their cerebrum appears to be thicker and heavier than common dyitzu. Broca's and Wernicke's areas of the brain do not appear to be denser, so their language abilities do not appear to be directly analogous to ours. It has been noted that high dyitzu have a poorer sense of direction than their less intelligent counterparts. If a minotaur so chooses he can cause a dyitzu to be both high and dark. In these cases, such devils are called archdyitzu.
Dyitzu bodies appear to have similar thresholds to that of a human in terms of strength and damage. Dyitzu meat is strong and gamey, but as tough as one might expect. It is extremely nutritious and is considered a staple food source in Hell. In practice, almost every portion of the dyitzu is edible. Cultures have even been known to grind down their claws and ingest them with liquid. The taste of such a liquid is acrid and bitter and one must question the motivations of such cultures.
