Iv'e yet to come up with a name for this SCP but the idea is of a sapient, telepathic and telekinetic "Spirit" or other dimensional being. It can also tap into and use a type of energy from this dimension where it can then use this energy as it is on it's own, or convert it to other forms of energy such as electrical, heat, light and sound energy.
I picture it being a humanoid, appearing as a translucent or solid aura of color which it can change as to whether it wants to appear solid or translucent along with the actual color of the aura e.g. changing from black to red.
It would be a Euclid/potential Thaumiel as it's telepathic ability can be used to calm down and make docile most things that can think, such as Keters or breached SCPs. As well as this, it's ability to convert it's other dimensional energy could be used as a power source after more research. However, since it is capable of free will, it will never be fully predictable giving it's Euclid classification.
My main concern is that it will turn out as a "Mary Sue" SCP. Give me your thoughts on what you think works and what doesn't and if there are any SCPs already like it? Also feel free to suggest names for it. If I use a suggested name, the person whom suggested it will be credited in the final piece if they wish so. Another thing I would like to know is whether "Euclid/potential Thaumiel" SCPs are allowed as iv'e found nothing to say they aren't?
