Back in the day, a Marvel Comics series containing alternate history stories of the major Marvel characters. The Watcher would introduce each tale with an account of something that happened in Marvel continuity and then show us what would have happened if things had turned out differently. The ones I remember were:
There was another cool
one I can't remember the title of, but was essentially "What If The Thing
Just Went Totally Nuts?", in which Ben Grimm
's mind snapped after he turned into the Thing and he went on a rampage
. He fought the Hulk
and had an atom bomb
dropped on him and stuff.
