Here is the Zevers, a species similar to the Arzaics, but in their prehistoric form. They are aggressive and bestial in combat, being the most feared troops in the Kingdom of Arza. Obviously to develop the Zevers, I was inspired by the DC Comics character Doomsday, especially the character's spikes and bestiality. So enjoy. Thank you.

The Zevers
The Zevers, which in Arzaico is "beast", are the prehistoric race of the Arzaicos, that is, the Zevers with the passage of time evolved to be the Arzaicos, but many of them preserved their prehistoric nature.
Its characteristics are similar to the Arzaicos, but with the difference that, in its extremities, its neck, its torso and back it is made up of scales and bone structures, which function as spikes. On the face, they have horns and ears of a wolf like an arzaic, in their snout their teeth stand out for their size. In the center of the neck, it has hard scales that function as protection, in the same way in the torso. On the back of the neck and shoulders they have spikes and scales, and in the same way on the torso, on its back it has hard scales that protect its spine. In the extremities, in the part of the forearm and the leg, they are formed by scales and on top of it bony parts that work barbs to hurt their opponents, especially in their hands or forearms they have retractable barbs that they use as weapons.
It is an immensely powerful species for combat, since its thick and hard scales function as an armour for vital organs in the face of bladed weapons, and even fires, its exposed bone structures, used by sharp spikes to attack their enemy, possess great strength like the Arzaicos, and great speed, but not like a Dracher. In addition, that their appearance is terrifying for their enemies, causing a psychological fear and, they can get used to extreme temperatures and any ecosystem due to their prehistoric past.
Zevers are extremely aggressive creatures at the time of combat, but they have control over their animal instincts. The males are trained for combat and hunting, having a demanding training at an early age, while the females are dedicated to taking care of the young, gathering food and caring for the wounded, but they are also extremely skilled in the attack. and espionage. And although these gender roles were stricter in the past, they are now more equitable, with females being more included in combat.
During the expansions of the Arza Kingdom, many emperors did not want to send it to the battlefield mainly because of its limitless aggressiveness and bestiality, something that is against the Arzaic War Codes, although some emperors sent them to instill fear in opponents. With the expansion of Spiker, one of the most bloodthirsty chapters of the Zevers, was the invasion of North Indochina, where the tribes were slaughtered by the Zevers without mercy, attacking adults, abducting women and destroying their homes. After the defeat of the Kingdom of Arza, the Zevers also suffered isolation, but in addition the use of troops made up of Zevers, by the aristocracy of the kingdom, was prohibited. Although this angered several Zevers, because it was their way of life, many emperors tried to integrate the Zevers into other fields of the kingdom, although several resisted denying their fighting personality.
There is no doubt that the Zevers are the most ferocious creatures of the Kingdom of Arza, their abilities and bestiality, make them one of the most dangerous troops that the Kingdom and the emperor have.
