In another thread, we were asked to reinvent the X-Men's history for funsies. I went back to the very beginning, but spent a good chunk of my ideas moving pieces around in the formative decade of the 80s. I decided the most essential formative events of the 80s were 1. Dqys of Future Past, 2. Mutant Massacre, 3. Inferno, and 4. X-Tinction Agenda.
I'm not asking to revised history here, but to debate what do YOU all feel are the 3-5 most significant roster-changing, concept-turning events of the 90s ... and I'm including Morrison's early 2000s run in the decade since it kind of caps off the era.
X-cutioner's Song? Fatal Attractions? Phalanx Covenant? Operation: Zero Tolerance? I think Age of Apocalypse and Onslaught are easily the two biggest. What do you think?
