Originally introduced in the early 1990s as Superman villains, Blaze and Satanus are powerful twin demons who are among the rules of Hades. They are also the estranged children of the Wizard Shazam, from his younger days as the ancient Canaanite superhero Vlarem The Champion. While Satanus has a soft-spot for his father and assists him from time-to-time (including giving life to Tawky Tawny), Blaze hates the Wizard and stages attacks on both him and the Marvel Family, believing the power of Shazam to be her birthright.
