What it is. OCD stands for Obsessive Compulsive Disorder. The person who has it pretty much gets thoughts based on fears or unreasonable thoughts that causes repetitive behavior. Here's an example because I didn't explain it very well... I don't really know how to explain it better. Somebody with OCD may have to touch a door handle a certain way or pick things up, put them down, or pick them up again. If they don't do things right, they may believe something bad is going to happen to them or someone else.

Quirk time.

It's called Repeat

The person has the ability to make someone repeat anything. Whether it was an action, or something they said

A drawback is, when they use it too much, they start to repeat random actions themselves

If you have any other disease or disability, be sure to let me know and I'll add it
