Smily

Smily (Aka: DSD: Destructive Smile Demon) is a large smile with two white eyes, everything behind it is completely black, it was created by demons, it can destroy walls and doors, it does that by just touching them and they will be obliterated, this happens because of a shield, anything that touches the shield will be destroyed, the only thing that isn't destroyed are demons which created it, it does not have a gender, past life or a soul, it seems to love red, if a living has red anywhere on its body will alert it and it will immediately attack the living thing even when it is not in its field of vision because it wants more red, it can even destroy blessed walls to see more red, the only way to not be killed is by having a different colored blood, when Peter was walking by its cell with a backpack with a red decoration it attacked him but after realizing his blood was blue, it then breached containment

Containment procedures
Standard containment cell blessed with holy water

Destruction Procedures
Its shield is not untouchable, blessed things can go through the shield, if you bless a gun and its ammo the bullet will go through the shield and hit Smily, however this will only keep it away for a year, one year later it will return to kill more

Method of killing
Heavy torturing, so much torture that the victim bleeds more blood than a whale, it seems to create the blood just to see the bleeding, the victim won't die until it has felt enough pain

Trivia
Smily is based on Specimen 9

Smily was originally gonna be called "Taker" which is Specimen 9's name

Just like most shades Smily will create a light under itself

Smily was never going to be a specimen, it only became a specimen because Peter didn't create a specimen based on Taker and he couldn't just leave it alone so he picked up one of his old ideas which was a smile in a dark background and used it as a specimen
