But here's the finale with the two meeting for the very first time. Unless of course you want me to post the hijinks that ended their relationship (for now) with Dark Avengers #1-3.
From Iron Man vol. 1 #150 ah first meetings:
You do what Doom? Boink her? Heh.. but alas Iron Man for the cockblock when Morgana cuts and runs after Tony attempts to stop the zombie army she raised at the source (being her). Doom of course is not amused at being abandoned and thus leads us to where part 1 is about into the reunion.
