Uncanny Treks: New X-Men Vol. 1- “E is for Extinction” (2002, Comic)

Grant Morrison's X-Men starts with a genocide. Bob and Matt begin the landmark run with E Is for Extinction — Cassandra Nova, Xavier's evil twin, annihilates 16 million mutants on Genosha in the opening arc, and nothing about the X-Men is safe afterward. New black-and-yellow uniforms, new students, new rules. Matt's bracing for the weirdness; Bob's already converted. The most important X-Men run of the century starts here.
