Uncanny X-Men #379 (4/00) - The X-Men try to relax after their confrontation with Apocalypse with a baseball game. However, their afternoon of recreation is interrupted when the High Evolutionary appears and tells them that he believes mutants and their powers will be the doom of mankind. In his attempt to "save" humanity, he causes every mutant on the planet to lose their powers. Marrow still has small horns on her head after her transformation.
