From the 1st world of EARTH, shadow blood is evil risen out of the dirt.  He was created by the blood of the EVIL ONE and brought to life with the formula and the Magic of the Beast of Sound.  Some feel there is no more EVIL than shadow blood. He is able to give yes or no binary style choices to many in crisis situations.  Often times he reveals a way out of the evil circumstance by infusing it with his own agenda.  Some think he works for the beast of noise.  This is clearly not the case as often times he acts on his own evil free will using blood of animals and dead immortals from the spirit worlds, he has the power to create creatures much like himself.  He is 50 percent shadow spirit and 50 percent immortal blood.
