Doug: Here's a weekend poser for you: given the Silver Age, and predating the deaths of Gwen Stacy and the Green Goblin in 1973, which single character's death would have totally reshaped the Bronze Age as it actually played out? So in other words, as Silver gave way to Bronze, which character's death (from any company), would have forever altered the landscape as we've come to know it? This is sort of a combined Open Forum and What If? post all in one -- but I want everyone to feel free to chime in with their own suggestions. Also feel free to play off of what others say; it's certainly fine to have multiple conversations flying around within the comments on this post!
Doug: I'll start by offering that the death of Reed Richards would have changed not only the lives and future of the Fantastic Four, but of the Inhumans, Avengers, potentially the X-Men, and indeed the entire Marvel Universe. Does Dr. Doom win in the end? Or, without his lifelong nemesis, does he lose all motivation and become a benevolent middle-European monarch concerned on whether or not his tiny fiefdom should join the EU? Does Sue take off with Namor? What if Doom, in his newfound niceness, cured Ben? What of the FF? Do they even exist at all? If Reed isn't there to cure Crystal from whatever was ailing her just before she took off to shack up with Pietro, does she die, pushing Johnny over the edge? One thing's for certain -- we wouldn't have to deal with that modern Civil War or Illuminati crap!
Doug: So who's your game-changer? Lois Lane? Doom himself? Peter Parker? Maybe Professor X was never "revived"? Let's hear it!
