Zorkus

Have you heard of the legendary monster Zorkus? A being of complete darkness, that steals souls.

Appearance
Zorkus is, for the most part, a deep black color. He's lanky, and has only one thin arm, along with two legs. His face has a permanent white glow, as well as other parts of his body. He posesses two horns, and bushy hair.

Personality
Zorkus has a personality that.. can't really be described, since it happens to change frequently. In other words, Zorkus has severe mood changes. He could be chanting evil plans the one moment, and be completely confused with himself in the next.

The keypoints to his personality, though, include him being pretty coldhearted. He is - frankly - a psychopath. He doesn't know, or care, how others are impacted by his actions. He does not feel sympathy, guilt, or responsibilty.

Zorkus usually refuses to show any kind of weakness in himself, as he absolutely hates being looked down on.

The way he acts makes it seems like he has absolutely no regrets. Although..

Soul Energy Absorption
"I'll take away your SOUL! I'll make everyone DEAD!!"Zorkus prior ability is absorbing the soul of another, or rather, the energy of it. He can fill himself with power of others. Doing this will create a supernatural bond with the individual, meaning their death impacts Zorkus' strength.

Zorkus can potentially destroy a soul, if he exaggerates the pulling of energy.

Life Creation
Zorkus can create Living beings from scratch using dark matter. Though only when involving a soul, resulting beings will form into a unique, and sentient creature. His most remarkable creations are the Shadowlings.

Shapeshifting
Zorkus can change the shape of his body, such as extending his arm or growing bigger or smaller.

Liquid Mimicry
Zorkus can shift his body into some sort of ooze, which is highly toxic.

Illusion Manipulation
Zorkus can make things be perceived differently than as they truly are. For example, he can make things disappear, multiply, move etc.

Though, Zorkus tends to make mistakes while doing this. Which makes it possible to see through them if you pay close attention.

Trivia
