Be sure to check out the Invisible Woman appreciation thread!
I'm kinda hoping this isn't part of that Avengers sub plot. Mephisto messing with the Marvel Universe from it's inception is an intriguing idea but if the end result is basically to fuse a bunch of random characters together that would be a let down. I mean this looks like it could be fun but I'd be expecting something better out of Mephisto manipulating all the major players of the Marvel Universe that than this.
I think you may be on to something.
Marvel was once "The House Of Ideas"
Then it became a "Condo Of Concepts"
Then an "Apartment Of Atrophy"
Then a "Trailer Of Terrible"
Then a "Tent City Of WTF"
Now it's a "Cardboard Box Filled With Bulls***"
"The Marvel EIC Chair has a certain curse that goes along with it: it tends to drive people insane, and ultimately, out of the business altogether. It is the notorious last stop for many staffers, as once you've sat in The Big Chair, your pariah status is usually locked in." Christopher Priest
... so if the Malibu characters can't "directly" be used (I doubt it) why not come up with some pastiche characters of them?
