X-Men Forever #13

In "Black Magik Part 3," the X-Men confront the Cossack’s twisted transformation of Illyana Rasputin into the dark sorceress Black Magik, as the team battles his Tartar werewolves while Kitty Pryde is drawn into a dangerous alliance that reshapes her with the powers of Firecat. Meanwhile, at the mansion, Beast and Jean share a quiet moment, Xavier and Nick debate the fragile nature of the mutant gene, and Sabretooth silences a rogue SHIELD agent with cold precision. Written by Chris Claremont and illustrated by Tom Grummett, with inks by Cory Hamscher, colors by Wil Quintana, and letters by Tom Orzechowski, the cover by Tom Grummett and Terry Austin captures the rising tension of this pivotal chapter.
