The Great Black Wizard has now his official thread!
It's a mysterious and evil guy and the only thing we know is that he created Draego-Man! (source: bio of Draego Man).
He has 2 indistinct appearances in the 3rd new mini comic. The GBW seems to be awesome IMHO.
He could be one of the evil mystics from the Dunes of Doom (Bcrduke)
He could be "the unnamed one".
Similar to the Chaos Sorcerer from Heroquest:
What are your opinion, assumptions and ideas about him?
