Peter David's X-Factor

Peter David's first X-Factor run (1991-1993) reinvented the team as a government-sponsored mutant squad. After the original X-Factor members rejoined the X-Men, Havok, Polaris, Multiple Man, Strong Guy, Wolfsbane, and Quicksilver were assigned to Val Cooper's program. David brought his trademark character-driven humor to the title, culminating in the legendary issue #87 — an entire comic devoted to a therapy session that remains one of the most acclaimed single issues in X-Men history. The run also ties into X-Cutioner's Song and the Genoshan political storylines.
