House of M: Civil War

In this 2009 Marvel one-shot, writer and artist Mike Perkins explores an alternate reality where the House of M's mutant-ruled world collides with the ideological schism of the Marvel Universe's Civil War. The issue reimagines the superhero registration conflict through the lens of a society where mutants hold power, offering a compact but potent "what if" scenario. As a singular, self-contained story, it provides a standalone glimpse into a divergent timeline without continuing beyond its initial release.
