Darkus

The main character of imMortal, Darkus was formerly a human and a member of Shadow Beast Special Force who after his death was turned into Umbralyth against his own will after being experimented on by corrupting him with a shard of Dark Entity's remains which gave him incredible power but uncontrollable desire for destruction. He was later merged with the weakened Light Entity who gave him the power to overcome the corrupting side effect of the shard's power. Along with the Light Entity he fights other Umbralyth turned creatures while trying to put an end to the Great War and to prevent the resurrection of the Dark Entity.

As a human
Darkus appeared as a muscular and tan-skinned man with androgynous face, average height, and long black hair with bangs on either side of his face, he usually kept his hair as low ponytail and he wore a lipstick.

First Stage
After being resurrected and mutated by the Dark Shard, Darkus underwent a violent mutation that caused him to grow in size, his skin became pale and gruesomely scarred with blood sometimes flowing out of them due to the forced growth by the mutation. Some of his hair fell off leaving him with much shorter hairstyle. His eyes were red and blood was flowing out of them. He gained claws on his hands and feet as well rows of sharp teeth in his mouth.

Second Stage
In this form Darkus became slightly bigger and he gained shark/fish-like attributes after absorbing some sea creatures such as Ginsu Shark, Scorpionfish, and Viperfish. His head became a mix of human and shark while his hair completely fell off. His skin became darkened as if it was burned, the scars across his body became more prominent. He gained shark gills on each side of his neck as well a dorsal fin and spines running down from the back of his neck all the way to his back. His hands and feet became webbed allowing him to swim better.

Third Stage
After absorbing more sea creatures such as Bull Shark, Goblin Shark, Moray Eel, Armored Searobin, and Electric Ray, Darkus' appearance became more much less human. His head became more shark-like with two pairs of long fangs on each jaws and he gained pharyngeal jaws. He gained a shark-like tail which nearly as long as his body. Bony armor grew from his snout all the way to his tail which gave him more durability against attacks. The claws on his hands and feet became longer and sharper. The spines on his back became more developed and jagged in shape, they sometimes emitted red electricity.

First Metamorphosis
After merging with the Light Entity and undergoing metamorphosis to undo his mutation, Darkus managed to turn his body back to look more human. In this form he had similar build to his true form albeit with bleached and scarred skin, red eyes, and short hair.
