Here are his stats:
Powers: Shuma-Gorath is a extradimensional demon and is therefore immune to disease and aging. In his native dimension he is virtually omnipotent. He generates his own mystical power, but is also able to draw energy, mystical or otherwise, from others. Shuma-Gorath can release destructive magical energy blasts and can manipulate magical energy on a planetary scale. He is able to communicate telepathically and compel others to do his will, even across dimensions. His skin is rubbery and armored, preventing physical damage. He has between 6 and 8 appendages, depending on his form. These are used to grasp/crush his prey and to project his energy blasts. It also may be impossible to permanently destroy him.
