X-Factor

X-Factor: The Original X-Men Omnibus Vol. 3 is the transition toward the end of the original-team experiment, carrying the fallout from Apocalypse, Nathan Summers and the team's public identity into a changing 1990s mutant line. The appeal is completion and Cyclops, Jean, Beast, Iceman and Archangel closing the chapter before X-Factor becomes a very different book.

X-Factor: The Original X-Men Omnibus Vol. 2 is the emotional crisis volume of the original-team era. Inferno forces Cyclops, Jean Grey, Madelyne Pryor and baby Nathan into one of the X-line's cruelest family knots, while Judgment War pushes the team into a stranger science-fiction register. It is central for understanding why X-Factor matters beyond the reunion premise.

X-Factor: The Original X-Men Omnibus Vol. 1 is the reunion volume with a cost: Jean Grey returns, the original five form X-Factor, and the team publicly pretends to hunt mutants while secretly rescuing them. Louise and Walt Simonson turn what could have been a nostalgia gimmick into myth, introducing Apocalypse and transforming Angel into Archangel.
