In his first adventure, the Master Mystic battled Rango, an evil Slovanian scientist who made himself a giant to exact revenge upon those who foiled his attempts at world domination.

He had a tower "at the top of the world".

Master Mystic had developed to the utmost the power of mind over matter, which allowed him to defy gravity, project his voice to thousands, turn into vapor, create materials from nothing, emit "liquidating rays" from his mind that destroy objects by "melting" them.
