Now, let's see: Corsine was first mentioned by name in the comic way back in the middle of our 17th storyline, "Cradle to Grave." There are more references to his mob here and there in the subsequent storylines, but Corsine himself first appeared at the very beginning of our 27th storyline, "Foreign Correspondence," only to meet his well-deserved and fairly messy end in the 28th storyline, "This Mortal Coil."
This being the sort of comic it is, however, that wasn't the end of him: he next showed up as one of the conspirators trying to overthrow the Devil and drive him out of Hell during our 50th storyline, "Adagietto," but he's been pretty quiet since then...
