I'm slowly filling in the gaps in my collection of the original run of Defenders, and I recently picked up #111. Defenders #111 attempts to resolve a thread from the Six Fingered Hand storyline, where it's stated that Hellcat is Satan's daughter.
In Defenders #111 Satan shows up while Hellcat is looking for her dad. He first appears in the guise of Nicholas Eblis. He turns into Satan who tortures Hellcat briefly, then explains how the underworld works and gives her a pep talk. He admires Hellcat and appreciates that she made his son (Hellstorm) fall in love.
Eblis shows up a year later in a Marvel Fanfare story featuring Man-Thing (vol 1 #9, I think...). In that story Eblis is gathering souls for his demonic boss, but ends up losing the souls and getting punished by his boss.
SO, I'm left wondering what it all means. Is Elbis a "catch all" identity that any demon uses? That doesn't feel right.
It's possible that Eblis really is Satan, and in the Marvel Fanfare story he pretended to be subserviant to another demon, but it seems more likely to me that Eblis is some other demon who was manipulating Hellcat's search for her dad for some reason we never learn.
Anyone happen to know these stories well enough to concur or disagree?
Nicholas Eblis is just a lackey that channeled his boss, Satan.
