ok! so! The idea I have is quite confusing but bare with me!
Basically! I have begun writing stuff and here is a rundown!
It is essentially a small/young child in appearance. It is sort of Albino with partially translucent skin and no organs other then a brain (It also has a malleable bone structure that can be seen through it's skin). It has no face other then a mouth. Instead of muscle and tissue it is filled with a clear substance that can see, hear and smell (Its confusing).
It is friendly to women and are attracted to them when they sing, this is how the SCP can be lured back to it's holding cell during a containment breach.
It hates anything that is Male. The reason why is unknown.
It likes to read and is rather intelligent but does not like sharing intelligence with others. It is provided toys and books to read as well as a comfortable environment to live. Any change to the environment can be dangerous. The SCP can be likened to a child with Aspergers syndrome and is set to a daily routine that shouldn't be interrupted unless the SCP is warned about it and is prepared.
It has the ability to reflect any force (Object/thing) that is against it and can change the power of that force to be stronger or weaker. So if you throw a ball at it hoping to harm it the ball will come straight back to you possibly injuring or killing you because it can make the ball have more force (Speed and velocity) then before.
if you want to know more, I can add the link to the sandbox page.
