KASAAVIN
The Kasaavin were beings that could phase through walls, even those of the Doctor's TARDIS. Their actual appearance is unknown but when the Doctor encountered them, they took on a humanoid appearance made of light because the shape "amused them"]. When they emerged through a surface, they temporarily took the image of that which they had passed through.
The Kasaavin planned to "take" the Doctor's universe.
