X-Men: Genesis #4 (4 of 5)

The X-Men’s day takes a deadly turn when a feral and relentless attacker infiltrates the mansion grounds—one with claws as sharp as his temper. But when the dust settles, the team is stunned to learn this savage warrior isn’t a stranger… he’s an old acquaintance of Professor Xavier, and he’s here with a warning: the Brotherhood is deadlier than they can imagine. As Cyclops and the newcomer clash over leadership and trust, Sabretooth strikes, proving that Magneto’s game is already in motion. But was this battle just a feint for something far worse? With tensions rising and danger closing in, the X-Men may be walking straight into a trap.
