Nice to see an OC that isn't a teen

Gender: male

Okay

Oh, similar to one my OC's, except mine has a specific doll they possess, they refuse to possess anything else.

Realistic and believable weaknesses!

Fair enough.

Do they kill: they do not kill, they make others kill

Cool!

How they kill: they cause children to grow into odd creatures that then grow obsessive hunger. These children keep there normal form accept when they kill someone by tearing through there body and eating there bones there teeth get sharper and their hands become more like claws.

This actually sounds quite unique. I love it!

Powers: bit of mind control that is only powerful enough to work on children and the mutation the children go through when under his control

Okay! Cool powers!

Creepypasta name: Glitch

Reason for killing: Glitch had lost his morals. He can no longer feel sorry for what he has done. He just needs to "care" for the children.

Fair enough.

Species: spirit

As someone who is fascinated by ghosts, spirits and the paranormal, I think it's really cool that your OC is a spirit!

Backstory: Rob used to work at a toy factory. He always loved bringing smiles to children's faces. But, his family wanted him to continue the bloodline. But every time he had adopted a child he would have to return the child to the adoption center because he did not have the skills to become a parent. His family was ashamed of him and would barely talk to him. He tried many times to get a child but was completely terrible at taking care of them. Finally, after Rob stopped trying to get a baby, his family had enough. His family got a book about dark magic and decided to use it on Rob. It was a spell to force anyone to have a child. Soon, Rob had gotten sick and eventually passed away. But before he passed away, a baby bursted out of his chest. His family pretended to mourn his loss but knew he was just holding the family back. They had raised the baby like there own until they turned 8 After the child turned eight they began acting strange. The child would always talk to there toys like they were talking back. Soon, the child began bringing other children in with no explanation and sit them next to a toy. Usually, this would confuse the parents but they did not think to much of it. But one night, they kept hearing the front door open and close. They went down stairs to see what's going on when they see there kids and multiple other children singing "Ring Around The Rosie" while spinning around a teddy bear in the center of their living room. Ten children grabbed the parents and rushed them to the center of the circle with the toy. Soon, the song stopped and the original child looked them dead in the eye. "He took care of us, but that wasn't good enough for you" the child said. The parents were confused until they realized something. All of the children were people there actual son adopted. "Time for you kids to feast" said the toy from a voice box in a somewhat glitching voice. The children rushed at the parents each scratching them and biting them in attempts to get to the bone. Soon, the father was dead and the last thing the mother saw was the toy, smiling.

Wow, this sounds like it should be the plot of a novel or a horror movie! I love it!

Overall, you have a great OC, and I can't really think of any faults. They're backstory is really creative too!
