Blockbusters are major events in the Marvel Megaverse. Certainly, what qualifies as an event is subjective: Generally, it is a combination of alliances of characters not usually banded together; intricacy of plots; significance of effects (either on the main participants, or civilians, affecting whole cities, nations, planets, etc.); and having a title helps, too. As always, space limitations dictate the content included in this handbook, so this appendix was created to be more complete; but even this list, which contains over 230 more events, had be trimmed, limiting description length and cutting some events entirely. Additionally, Acts of Vengeance, Contest of Champions and War of the Seven Spheres have been previously covered in the OHotMU A to Z hardcovers #1, 2 and 13, respectively. Future handbooks in 2011 and beyond will cover other events we could not fit into the Blockbusters handbook. Issues listed represent the first appearance of the event itself, not the prologue or build-up to the events; this listing is somewhat subjective, of course.
