The demon beasts were bizarre, he was no different. Head and body of a tiger, with teeth that could tear apart scales and claws that could severe bones; leathery wings of bat with 2 vicious talons that could puncture steel on the thumbs of the wings; 3 tails like that of a snakes, yet ending in sword like blades so fine it could slice leaves in layers; thorns protruding from each leg and shoulder, that render flesh at the slightest touch; fur like fine steel needles, making his whole body a weapon.
His body was so dangerous that the slightest movement could cause mortal wounds. But every beast had bodies just as dangerous. He was different in one way alone. His unparalleled tenacity ensured his victory in every skirmish.
As he established his territory, all beasts before him prostrated in fear of death. He made a den made with the bones of his enemies alone, his throne a bed of skulls.
As he reigned a region, he felt the thrill of conquest and moved onward. He faced the strongest of demons before taking their heads. The subdued who followed him had no hand in his battles. He did not care for them, it was only natural for the weak to follow the strong.
Eventually even those lords could no longer satisfy his thirst for war. He sought even higher opponents, and soon heard from an elder demon he subdued, of the monarch of the abyss.
The monarch wasn't so easily found, and had long grew bored of worldly matters, and only slept his years away in a secluded place. After scouring the abyss, he was found. His den was in the deepest of oceans, at a depth so dark that the abyss itself couldn't compare.
With his strength, he could hold his breath for days. He dove deeper and deeper, before making his challenge.
Out the expansive cavern came an enormous beast. The body of a bear, wings of an eagle, head of a lion, tail of a lizard ending with an enormous great sword like blade. There were visible pores on his body, from which abyssal flames was released with every breath.
This was the Abyssal Monarch, Pluto.
