MEPHISTO FIRST APPEARED IN SILVER SURFER #3 IN 1968 AND....

RIGHT THAT'S BETTER, NOW WHERE WAS I?
Oh, sorry, now where was I? So yeah, Mephisto first cropped up in the Marvel Universe in 1968 and he's pretty much been the big bad ever since.

Mephisto is also immortal, has magical powers, can alter time and he's practically invulnerable.
