What i've got so far is that it's a large biped reptilian with black colored flesh. It has PSI energies and must be contained with an aluminum box over it's head to prevent it from using it's PSI to cause damage. It communicates Via Telepathy, and occasionally american sign language (as it can't use it's telepathy with the box on). It highly enjoys human flesh although it won't usually attack those who come in to feed it. The foundation usually just gives it live goat or cow to play with and eat.
Please tell me what you think of this, and if it's too similar to any other current SCP's. (Have not read them all, so I might be similar to a real SCP)
