Zyuman is not your standard or typical deinonychus. For starters he stands just over four feet tall at the hips - this is cause theropods are measured at their hips. His underbelly is scaled for most of the year, this only changes during the colder months as those feathers are also used for incubating eggs. These underbelly feathers are a dull, ash gray to match the natural scale coloring. 

Along the arms the feathers here are darker in color. The color starts as a glossy black, slowly turning to a vibrant red. The very tips of the primary and secondary feathers end with a white tip. So when he swings his raptor arms out or holds them close, it creates a fine white line. The shades of red and black on the convert feathers are similar but without the white. All of the feathers have a unique feature, they are iridescent. Depending on his movements and his attitude, these reds and blacks create an illusion used to either warn, threaten, or attract a mate. The illusion created looks like blood is flowing from his wings. The white outline aids in this by making Zyuman seem larger than he really is. 

His tail feathers share this same feature and coloring pattern. The only real change is that near the tip of his tail the red and black pallet swap. So when he lowers his head and arch his tail up, it creates another illusion. Something bigger than him, glaring down with blood red eyes. This is only down to scare or intimidate rivals males instead of attracting a potential mate. 

The feathers along his back and heckles are a dark gray to match with his reptilian snout. Along the legs these feathers are a lighter shade of gray to better blend with the ash gray of his scales or downy feathers. 

The feathers that make up his crest behave much like that of the modern greater roadrunner, allowing a range of motions or signals for others. Like the feathers around the neck, they are a dark gray, but have a little iridescent so they tend to shift in brightness or darkness depending on the lighting. However, there's a pair of feathers that are blood red. When relaxed, the two are side by side with little overlap. When he starts to get his heckles up, the two red feathers part slightly, forming a very closed V shape. This turns into a more wider V, making him look more imposing, especially when angered. This is normally the last thing a person sees before he make a full on raptor lunge at them. 

Another difference between him and the earth holotype is that he has three digits plus a thumb on his hands. The claw on the thumbs are slightly curved for extra utility. His feet consist of three toes, instead of the standard two, plus the "terrible claw". These extras digits serve more to aid in scaling trees or vertical cliff faces, much like climbing cams and spikes for mountain climbers and loggers . He won't hesitate to poke an eye out or puncture flesh if it means escape or an easy meal, like a compy or velociraptor. 

Eyes are a dull topaz color. They can dilate  from a large, wide circular shape to a narrow slit that makes him look more reptilian. This allows him to hunt expertly no matter the light level. 

He has two evolved forms, depending on situation. His first evolved form his body shifts so that it is  mostly upright, but it's not perfect as the form has no defining human-like characteristics. His tail is shortened as balance when moving isn't as important. His arms are longer and shows some muscular definition, as well as his legs being still digigrade as he's still mostly feral in this form.  Feathers are also shorter and duller, losing their iridescent hues to them. He's roughly eight feet tall, but that's cause the shift only pulls the skeletal structure to an upright position. Cloaca is still part of this form, shifted slightly so it's not seen from the front, unless they try to peak under. 

The second form is more dangerous as it's humanoid in design. He loses a foot in overall height, but he makes up for it with raw bulk. Broad shoulders, meaty pecs, washboard abs, fit trimmed waist. Powerful legs. He still has the three fingers and toes, with the thumb and "terrible claw", but the build of the legs are clearly human in design. As are his arms. The feathers are mostly a fur-like fluff now, though not exactly fluffy. He does have a couple feathers on his forearms and calves, but they are more for show than anything else. His overall weight makes him too heavy to aid in slow falling when scaling cliff walls or trees. A pair of feathers on the forearm can do something as a very last resort. They are thin pin feathers that can be propelled when he clenches his claws tightly. This is extremely painful and will leave an obvious gap when returning to his feral form. His feathered tail is more like a fluffy whip as the fanned out feathers no longer exist. This tail is almost three feet in length and isn't afraid to spin around to knock you out with it.  His crest is still feathered and just as expressive based on mood. However, his male parts are now external instead of internal like feral and first evolved forms.

When he chooses to wear human attire, he tends to wear a red compression tank top and black spandex shorts. He does like being a show-off. Along with that, is rock climbing harness with several carabiners around the belt clips and a couple sets of climbing ropes. When he does wear the harness, he wears khaki colored cargo shorts. Foot gear is non-existent since he still has his clawed feet. They give him more grip than any footgear can provide.  The cargo shorts tend to be on his first evolved form or anytime the need for climbing is needed. 

On his left wrist, he was fused with a device that allows him to transform into any of his past dinosaur bodies. He called this device the "Dino-Volver". The upper half of the device can spin, but it doesn't normally move unless Zyuman decides to slap this section to make it spin. This is what activates the transformation sequence or any of finishing moves. It has a hex-shaped indentation that will fit the coins that The Den was able to create. This device can appear and vanish with just a thought, so it's not always there. This section can also be pressed slightly to create different effects. After inserting a coin, each press will change which form he'll take. Just placing the coin will result in the feral form or "normal form". One press of the Dino-Volver and he can turn into the first evolved form, if it is capable of standing slightly upright. Not all dinosaurs are capable of this first evolved form. A second press of the Dino-Volver prior to spinning will result it "Super Evolution" form, the humanoid form. Nearly every dinosaur in his collection can turn humanoid. There are a few rare exceptions, but he never carries these coins. 

Finishing moves are done exclusively in the humanoid form as it allows the greatest of ease. With one press and spin allows for the most basic of finishing attacks, a single powerful punch. Two presses before the spin activates the Kamen Rider style kick. Three presses will make for the ultimate finishing move, it's normally a full body attack, sometimes ending with his tail striking the target. 

On The Den's bridge there is a sections that houses all these coins as well as the prototype Dino-Volver. This prototype was the original intention of the device, to show a holographic image of his past lives. It also contained info on when he was that particular dinosaur. Along with Earth's timescale as compared to the world he currently resides in. Take note, most of the dinosaurs currently surviving on the world are from different earth eras. The two worlds have similar evolution lines, but most are existing in the same era as others would later emerge. Case in point, the eoraptor is still thriving on this world, along side those that should have replaced them, such as compy.
