X-Men #10

In "Vielleicht auch träumen ...", Xavier leaves Earth with the mutant Skrulls to become their teacher, leaving the X-Men behind as the High Evolutionary declares that the only solution to the mutant problem is to erase the mutant gene and revert all mutants to ordinary humans—exactly what he proceeds to do. Written by Chris Claremont, Alan Davis, and Jürgen Petz, with art by Tom Raney and colors by Brian Haberlin, this 2001 issue from Panini Deutschland captures a pivotal moment in mutant history, its cover by Adam Kubert and Tim Townsend reflecting the gravity of the departure.
