"Symposium."

Ooh, wordy one this week. 

So this one is probably directly drawn from old Silver Age Superman comics, which often featured Supes casually smashing an asteroid or something heading toward earth before the plot even started, just part of a normal Tuesday for him. Any time Superman gets removed from the timeline, then, the story should be over before it starts! Lex Luthor (or whoever, but probably Lex) goes back in time, stops Kal-El's rocket from getting to earth, or kills him as a kid, whatever; and he would return to a destroyed planet. A destroyed planet probably dozens of times over, for that matter. 

The other one would be around Excalibur #50: Merlyn, for reasons of his own, manipulated the team from day one, to get the right players at the right time to save the multiverse. He's a total dick about it--he expected to lose more of them--but I don't think he ever came back after that? Not in that book, anyway.

Morbius has seen a ton of weird crap, but this is outside his wheelhouse, so he has questions. Remember in Endgame where the Ancient One was fighting the Chitauri during the battle of New York? You don't see Marvel's magic types vs. aliens very often, do you?  Have you ever seen Ghost Rider fight aliens? Probably at some point, just because there's been a ton of GR stories, but still.

I feel like someone has actually done part of this but then backed of; where Kang would go back in time to kill some baby Avenger or another: I absolutely could see him doing it, then feeling bad and erasing it, but definitely doing it. Kang was also going to mention, that the Avengers probably deal with these crises  (plural of crisis! I don't think it looks right either.) with far less collateral damage than he or Doom would have. But Doom had a line about "only dealing with problems once," which sounds Doom-like and ominous, but would also be an outright lie. Everyone there would probably have been "Cough! Richards! Cough!" and that would've derailed things even further...
