Written by PETER DAVID. Penciled by RYAN SOOK & DENNIS CALERO. Cover by RYAN SOOK. In the fallout from HOUSE OF M and following the surprise film-noir hit MADROX, a new mutant team is forged! X-Factor is an investigative mutant agency that includes Madrox, the Multiple Man; Guido, the Strong Guy; Wolfsbane, the shape-shifter; Siryn, the chorus girl; Rictor, the living earthquake; and Generation X's Monet, the pompous witch. Drawn together in the heart of District X, this rag-tag band of heroes has a lot of answers to find, and fast! Bonus: A key player from House of M will play a major roll in X-Factor! (No, it's not Wolverine - sigh.) Collecting X-FACTOR #1-6. 144 PGS.
