He is not normal. He will never be normal. You see, unlike literally every other monster in the world...

He didn't have a soul. 

He was born without one. He was a scientific mystery to many, but other than that, he seemed like a normal kid. He never really had any friends nor did he ever want one. Lacking a soul meant he lacked feelings, which stopped him from really caring about people, even his mom and dad. He was the smartest kid in the batch, but the most quiet one too. 

But as of lately, he had found a way of "feeling". What you don't have...you can just take.

Which he was trying to do now.

This was something he had done many times before. He was currently leading a "friend" down the street "to his house". "Here, I've got a shortcut down this alley." He beckoned them towards the alley, which they followed. Midway through though, he stopped walking abruptly. "Um, shouldn't we keep going?" In a quick snap, he turned around and grabbed their arms, stopping them from running away. 

It was so simple. Their soul was completely unguarded and granted him access to take whatever was in it. His eyes went completely black and an insane grin lit up his face as the emotions of the other flowed through his system. In a few seconds, the poor student was completely drained of life, and crumpled uselessly to the floor. He blinked a few times, his white eyes turning grey as it flooded with color. 

He never got caught for it, as skeletons had no prints they could leave behind. He made sure to be discreet about it, making sure no one saw him communicate with a soon-to-be victim. They would connect the dots after a while, and he would be found out. He can't have that now, can he? Draining the soul meant draining it of everything, so when the victim would wake up, they wouldn't remember anything. Not their name, their parents, that he drained them of any use they had to society...Besides, he was the "role model", the smart kid. Who would ever suspect him?

He laughed quietly. That soul should last him a good two weeks. He was about to teleport out when someone grabbed him through a door in the alleyway. He was about to shout and run away but immediately shut up when he saw who was looking at him.

"Well, well, well...look what the cat dragged in."

That was Nightmare, head of mafia.
