Rip Jagger's Dojo
That list includes two Marvel covers - one featuring Satan and one featuring Mephisto. I always got a bit confused over that- Mephisto was Marvel's version of Satan but in Ghost Rider and Son of Satan it's Satan himself we see and Mephisto is absent. But Mephisto is still important in the Marvel Universe as it was him who unmarried Peter and Mary-Jane in the Brand New Day controversy.
No kidding! Add Satannish to the list too and Thog. A lot of these guys were demoted to minor demons, but when they showed up the first time, I think they were all supposed to be the real deal. Rip Off
